In Rawls’ influential social contract approach to distributive justice, the fair income distribution is the one that an individual would choose behind a veil of ignorance. Harsanyi treated this situation as a decision under risk and arrived at utilitarianism using expected utility theory. This paper investigates the implications of applying cumulative prospect theory instead, which better describes behavior under risk. I find that the specific type of inequality in bottom-heavy right-skewed income distributions, which includes the log-normal income distribution, could (...) be perceived as desirable. This optimal inequality result contrasts the implications of other social welfare criteria. (shrink)

From the 1980s onward income inequality increased in many advanced countries. It is very difficult to account for the rise in income inequality using the standard labour supply/demand explanation. Fiscal redistribution has become less effective in compensating increasing inequalities since the 1990s. Some of the basic features of redistribution can be explained through the optimal tax framework developed by J.A. Mirrlees in 1971. This Element surveys some of the earlier results in linear and nonlinear taxation and produces (...) some new numerical results. Given the key role of capital income in the overall income inequality it also considers the optimal taxation of capital income. It examines empirically the relationship between the extent of redistribution and the components of the Mirrlees framework. The redistributive role of factors such as publicly provided private goods, public employment, endogenous wages in the overlapping generations model and income uncertainty are analysed. (shrink)

Integrated assessment models (IAMs) of climate and the economy provide estimates of the social cost of carbon and inform climate policy. With the Nested Inequalities Climate Economy model (NICE) (Dennig et al. PNAS 112:15,827–15,832, 2015), which is based on Nordhaus’s Regional Integrated Model of Climate and the Economy (RICE), but also includes inequalities within regions, we investigate the comparative importance of several factors—namely, time preference, inequality aversion, intraregional inequalities in the distribution of both damage and mitigation cost and the (...) damage function. We do so by computing optimal carbon price trajectories that arise from the wide variety of combinations that are possible given the prevailing range of disagreement over each factor. This provides answers to a number of questions, including Thomas Schelling’s conjecture that properly accounting for inequalities could lead the inequality aversion parameter to have an effect opposite to what is suggested by the Ramsey equation.

How much should the present generations sacrifice to reduce emissions today, in order to reduce the future harms of climate change? Within climate economics, debate on this question has been focused on so-called “ethical parameters” of social time preference and inequality aversion. We show that optimal climate policy similarly importantly depends on the future of the developing world. In particular, although global poverty is falling and the economic lives of the poor are improving worldwide, leading models of climate (...) economics may be too optimistic about two central predictions: future population growth in poor countries, and future convergence in total factor productivity (TFP). We report results of small modifications to a standard model: under plausible scenarios for high future population growth (especially in sub-Saharan Africa) and for low future TFP convergence, we find that optimal near-term carbon taxes could be substantially larger.

Integrated assessment models of climate and the economy provide estimates of the social cost of carbon and inform climate policy. We create a variant of the Regional Integrated model of Climate and the Economy (RICE)—a regionally disaggregated version of the Dynamic Integrated model of Climate and the Economy (DICE)—in which we introduce a more fine-grained representation of economic inequalities within the model’s regions. This allows us to model the common observation that climate change impacts are not evenly distributed within regions (...) and that poorer people are more vulnerable than the rest of the population. Our results suggest that this is important to the social cost of carbon—as significant, potentially, for the optimal carbon price as the debate between Stern and Nordhaus on discounting. (shrink)

Thomas Piketty’s Capital in the Twenty-First Century makes hardly any reference to the ethics of inequality. Surprisingly, this is an omission shared by most of his critics. In this paper I investigate the literature on which he and his reviewers might have drawn and speculate on the reasons why they did not. I outline the four ‘views of society’ and the related issues in moral philosophy that were presented by Michael Schneider in his book on the distribution of wealth. (...) I then summarise the criticisms of Piketty made by those few reviewers who did show some interest in ethical questions and examine the slightly earlier and quite different case against reducing inequality made by one of these critics, N. Gregory Mankiw. I consider the economic, political and social costs of inequality identified in a book-length study of Piketty’s work by Steven Pressman, and conclude by reflecting on the reasons for the widespread neglect of moral philosophy by mainstream economists.

Recognizing the variety of dystopian science-fiction novels and movies, from Brave New World to Gattaca and more recently Star Trek, on the future of humanity in which eugenic policies are implemented, genetic engineering has been getting a bad reputation for valid but arguably, mostly historical reasons.

We present a general method for obtaining all Bell inequalities for a given experimental setup. Although the algorithm runs slowly, we apply it to two cases. First, the Greenberger-Horne-Zeilinger setup with three observers each performing one of two possible measurements. Second, the case of two observers each performing one of three possible experiments. In both cases we obtain hundreds of inequalities. Since this is the set of all inequalities, the one that is maximally violated in a given quantum state must (...) be among them. We demonstrate this fact with a few examples. We also note the deep connection between the inequalities and classical logic, and their violation with quantum logic. (shrink)

We study how the optimal contract in team production is a¤ected when employees are averse to inequity in the sense described by Fehr and Schmidt (1999). By designing a reward scheme that creates inequity o¤ the desired equilibrium, the employer can induce employees to perform e¤ort at a lower total wage cost than when they are not inequity averse. We also show that the optimal output choice might change when employees are inequity averse. Finally, we show that an (...) employer can gain, and never lose, by designing a contract that accounts for inequity aversion, even if employees have standard preferences. (shrink)

Modest difference in individual decisional skills may warrant substantial inequality in power. This claim has been illustrated in Ben Yashar and Nitzan (Economics Letters 174:93–95, 2019), applying the symmetric uncertain dichotomous choice setting and focusing on the skill-dependent (s-d) power of the decision-makers under the optimal decision rule. The same claim is valid when one focuses on the relationship between skill heterogeneity and the distribution of the second type of power, viz., the group members' marginal contribution (mc). This (...) has been shown in Ben Yashar et al. (Journal of Theoretical Politics 33(2):225–235, 2021), where mc has been formally related to s-d power. A preliminary study of the relationship between inequality of the distributions of the two measures has also been presented. The current paper considerably expands this investigation by applying simulations and sheds light on the reason for the increased inequality of the two types of power. Since reward (in terms of status, payment or both) depends on s-d power and mc, inequality of the distribution of rewards depends on the inequality of the two types of power. Comparison of the two types of power inequality is therefore interesting if one wishes to shed light on the role of the two types of power on reward inequality. In particular, the results of the comparison may clarify the effectiveness of the incentives to invest in skills, dependent on the prevailing norms and the institutional characteristics that determine the relationship between rewards and the two types of power. For this reason, the current study focuses on the comparison between inequality of s-d power and marginal contributions showing that, in small (large) groups, on average, the latter is more (less) unequal than the former and both are more unequal than the optimal weights of the decision-makers and much more unequal than their skills. The robustness of these findings is shown by applying alternative symmetric probability distribution functions. Another novel task undertaken in the current study is the sensitivity analysis of inequality of the power measures with respect to changes in the size of the group and the skills of the group members.

Compared to a charging scheduling and management problem characterized by predetermined trip assignment, this study takes bus and driver scheduling into account, and mealtime windows must be guaranteed as one of the major labor regulations. A discretized mixed-integer linear programming model is developed based on a single electric bus route. We aim to obtain fast and high-quality global solutions for this problem, and the model can be easily executed by bus operators by directly invoking an available optimization solver such as (...) IBM ILOG CPLEX. We test our model on a real round-trip bus route. Numerical experiments show that CPLEX takes approximately 6 sec to obtain an optimal solution. The model can not only reasonably arrange daily trips for each electric bus and driver but also effectively determine the optimal charging schedule and management for an electric bus line. Besides, we analyze the sensitivity of the key parameters in the model. With the increase in the drivers’ maximum workload, the drivers’ average idle time decreases by approximately 11.25%. The objective value decreases by approximately 38.71% and 40.04% with increases in the battery capacity and fleet size, respectively, and the objective value increases by approximately 30.06% with the decrease in the initial battery driving range. In addition, we compare the effectiveness of our time discretization modeling method in solving the same case study to that from other similar studies, and the validity of our method can be verified by the calculation time. We also compare the computational efficiency of CPLEX in solving the same case study problem with and without implementing valid inequalities, and the computational efficiency of the valid inequality method is greatly improved. Finally, through the testing of a multiline network, the potential application of the model to a large-scale traffic network is verified. (shrink)

The levelling down objection is the most serious objection to the principle of equality, but we think it can be conclusively defeated. It is serious because it pits the principle of equality squarely against the welfares of the persons whose welfares or resources are equalized. It suggests that there is something perverse about the principle of equality. In this paper, we argue that levelling down is not an implication of the principle of equality. To show this we offer a defence (...) of, and partial elaboration of, what we call a common good conception of the principle of equality, which principle favours states in which everyone is better off to those in which everyone is worse off. We contrast this with what we call a purely structural conception of the principle of equality. The common good conception of equality involves two basic components: (1) in each circumstance there exists an ideal egalitarian distribution, which distributes equally all the available good in the distribution with the highest average welfare and (2) in evaluating how just the world is, it will matter how far the actual distribution is from the ideal distribution. The ideal egalitarian distribution in the circumstance is Pareto optimal and the approximation rule implies that Pareto superior states are less unjust than Pareto inferior states. 1. (shrink)

As scientific progress approaches the point where significant human enhancements could become reality, debates arise whether such technologies should be made available. This paper evaluates the widespread concern that human enhancements will inevitably accentuate existing inequality and analyzes whether prohibition is the optimal public policy to avoid this outcome. Beyond these empirical questions, this paper considers whether the inequality objection is a sound argument against the set of enhancements most threatening to equality, i.e., cognitive enhancements. In doing (...) so, I shall argue that cognitive enhancements can be embraced wholeheartedly, for three separate reasons. However, though the inequality objection does not sufficiently support the conclusion that cognitive enhancements should be prohibited, it raises several concerns for optimal policy design that shall be addressed here.

Most people in the United States agree they want some income inequality but debate exactly how much is fair. High‐status people generally prefer more inequality than low‐status individuals. Here we examine how much preferences for inequality are (or are not) driven by self‐interest. Past work has generally investigated this idea in two ways: The first is by stratifying preferences by income, and the second is by randomly assigning financial status within lab‐constructed scenarios. In this paper, we develop (...) a method that combines both experimental control and the social experience of inequality—a simulated society experiment. Across two experiments (N = 138, observations = 690), participants voted on the distribution of rewards—first behind a veil of ignorance, and then when they were randomly assigned a status within a game of chance. Status varied repeatedly across five rounds, allowing us to measure dynamic preferences. Under the veil of ignorance, people preferred inequality favoring the top status. When the veil of ignorance disappeared, self‐interest immediately influenced inequality preferences. Those who randomly landed in top positions were satisfied with the status quo established under the veil of ignorance, whereas those who randomly landed in bottom positions wanted more equality. Yet these preferences were not stable; decisions about the optimal level of inequality changed according to changes in social status. Our results also showed that, when inequality grows in a society, preferences regarding inequality become polarized by social status. Individuals in low‐status positions, particularly, tend to demand more equality. (shrink)

Existing estimates of optimal climate policy ignore the possibility that carbon tax revenues could be used in a progressive way; model results therefore typically imply that near-term climate action comes at some cost to the poor. Using the Nested Inequalities Climate Economy (NICE) model, we show that an equal per capita refund of carbon tax revenues implies that achieving a 2 °C target can pay large and immediate dividends for improving well-being, reducing inequality and alleviating poverty. In an (...) optimal policy calculation that weighs the benefits against the costs of mitigation, the recommended policy is characterized by aggressive near-term climate action followed by a slower climb towards full decarbonization; this pattern—which is driven by a carbon revenue Laffer curve—prevents runaway warming while also preserving tax revenues for redistribution. Accounting for these dynamics corrects a long-standing bias against strong immediate climate action in the optimal policy literature. (shrink)

Quantum state targeting is a quantum game which results from combining traditional quantum state estimation with additional classical information. We consider a particular version of the game and show how it can be played with maximally entangled states. The optimal solution of the game is used to derive a Bell inequality for two entangled qutrits. We argue that the nice properties of the inequality are direct consequences of the method of construction.

In a supply chain system, the prices with which the suppliers supply its local commodity to the retailers should satisfy the requirements of the retailers and the consumers. The supply and demand scheme satisfying these requirements is reduced into fuzzy relation inequalities with min-product composition. Due to the difference between the min-product composition and the classical max-t-norm one, we first study the resolution of such min-product FRI system. For optimization management in the supply chain system, we further investigate a maximin (...) programming problem subject to the min-product FRIs. An algorithm is proposed to obtain the optimal solution based on the quasi-maximal matrix and corresponding index set. To illustrate the efficiency of our proposed algorithm, we provide a simple numerical example. The obtained optimal solution reflects an optimal pricing scheme, which maximizes the minimum prices of the commodity from the suppliers. (shrink)

Inequality of incomes is one of the significant factors forming the social capital. Two views dominate among economists dealing with the influence of inequality of income on economic growth. On the one hand, a too low inequality of income does not motivate people to increase the labour productivity. A low inequality of income might result from an extended social care system and overloading GDP with social transfers. A good example of it may be a situation when (...) the unemployed refuses to accept a job offer and prefers the unemployment benefit rather to a slightly higher salary. Moreover, a lack of incentives for the employee who fails to acknowledge the economic sense of increasing the productivity of his work might lead to the slower growth of economy. On the other hand, a contrary view suggests that an increase of the inequality of income has a negative impact on the economy. The accumulation of wealth by a small number of citizens raises doubts about good use of that wealth for investments necessary for the growth of the economy. An excessive inequality of income is confronted with disapproval of the significant part of society and regarded as unfair and unjustified. It may also increase the crime level and decrease the trust and, more generally, lead to the weakening of social capital. The arguments above lead to a hypothesis that the influence of the inequality of income on the growth of the economy has a non-linear character. We confirmed this hypothesis in growth models of the US and Swedish economies. We assess the historically optimal inequality of income measured by the Gini coefficient at 46% and 24% for the US and Sweden respectively. The optimal inequality of income in Poland was assessed previously at 29%. The dissimilarities may result from the cultural differences, educational level differences, ethnic differences and differences in diligence. (shrink)

Responsibility is a moral quality of caring that is central to child health policies. In contemporary UK these policies are based on behavioural psychology and underpinned by individualism, an ideology central to neoliberal governance. Amid the complexities of “obesity” and inequalities, there is a multi-layered stigmatisation of parents as moral associates. Few studies consider the lived realities of food policy processes from the standpoint of class. This critical qualitative research draws on theorists who explain processes of power and class: Foucault, (...) Gramsci, Bourdieu and Marx. Its objectives are: (a) to understand the lived experience of parents as they interact with food policy; (b) to explore how parents resist stigmatisation; and (c) to reflect on implications for policy and practice. Methods: Using purposive sampling, 31 ethnographically-informed interviews were carried out in a London borough, with policy actors: policymakers, implementers and parents as policy recipients, including 12 working-class mothers. Results: A core theme of “responsibilities” emerged with four interconnecting sub-processes that provide insight into how stigmatisation and resistance evolve through policy. Discussion: As have others, this study reveals the idea of responsibility as fundamental to the processes of soft power. Child health is a priority for participants and a “ruling idea”. The diffusion of responsibility throughout policy leads to confusion about where it lies. New subjectivities are formed in line with ideas of governmentality. Parents engage with policy at multiple sites that elicit symbolic violence, and stigma sows social divisions. Against this background, working-class parents are left in a state of cognitive dissonance between being made responsible (responsibilisation), and feeling responsible (self-blaming) for their children’s weight while lacking the material resources to provide an optimal nutritious diet. Resistance is interwoven and is essentially found in parents’ policy alternatives that diverge from UK government policy. Conclusion: Critical qualitative research using multiple theorists is valuable in understanding how parents interact with policy in a complex social world. With UK policy failing, useful insights are provided into how involving parents in policymaking might determine a meaningful collective responsibility, with a political ethic of care and unity between parents that would advance health equity.

A lifting is a map from the state of a system to that of a compound system, which was introduced in Accardi and Ohya (Appl. Math. Optim. 39:33–59, 1999). The lifting can be applied to various physical processes.In this paper, we defined a quantum mutual entropy by the lifting. The usual quantum mutual entropy satisfies the Shannon inequality (Ohya in IEEE Trans. Inf. Theory 29(5):770–774, 1983), but the mutual entropy defined through the lifting does not satisfy this inequality (...) unless some conditions hold. (shrink)

This paper draws on Friedrich Nietzsche’s work to defend the (admittedly non-Nietzschean) conclusion that a non-liberal egalitarian society is superior in two ways: first, as a moral ideal, it does not rest on questionable claims about essential human equality and, second, such a society would provide the optimal psychological and political conditions for individual wellbeing, social stability, and cultural achievement. I first explain Nietzsche’s distinction between forms of egalitarianism: noble and slavish. The slavish form promotes equality, defined negatively as (...) the elimination of privilege. It is non-liberal in its prioritization of equality over the interests of the advantaged. Nietzsche rejects both slavish egalitarianism and liberalism for the same reasons: they questionably assume the equal value of all persons, and they harm cultural achievement, sacrificing the potential of those who are most valuable to cultural development to the interests of the majority. Noble egalitarianism, in contrast, exemplifies Nietzsche’s conception of justice as ‘equality among equals’. It demands that individuals of equal worth or power (such as members of an artistic or political elite) treat each other as what they, in fact, are: equals. It avoids asserting essential equality, demanding instead—against both slavish and liberal forms—respect on the basis of shared superiority. And it escapes the charge of harm to cultural development, commanding respect only where equality already exists. Although Nietzsche quickly assumes that ‘noble egalitarianism’ requires the rejection of all forms of universal egalitarianism, concluding that we should ‘never make equal what is unequal’, in fact it only entails the rejection of slavish methods: equalization through harm to the advantaged. However, non-liberal forms of egalitarianism can be ‘noble’, promoting equality without harm to the advantaged—through, for example, unequal distribution of resources, the equalization of economic opportunities, and economic regulation to prevent the creation of substantial wealth disparities. If egalitarianism can ‘make equal’ without slavish methods, then Nietzsche’s demand for ‘equality for equals’ applies to the newly equal, too. More importantly, his moral psychology of power—the view that our source of happiness and incentive to self-development is the feeling of power in relation to equal resistance or ‘opponents who are our equals’ —supports the superiority of a nobly-achieved, non-liberal egalitarian society. For achieved, practical equality of wealth and opportunity would optimize conditions for the feeling of power: a balance of equal, oppositional powers serving as mutual limitation and resistance. Such a society is superior in three ways. First, it maximizes social happiness by promoting and maintaining the feeling of power in all. Liberal and aristocratic societies, in contrast, allow radical inequalities that not only diminish the power of the disadvantaged, but diminish the opportunities of the advantaged to encounter equal resistance, thus undermining the happiness of all. Second, it promotes social stability by preserving a balance of powers that prevents domination and exploitation, in contrast to the inevitable class conflicts of aristocratic and liberal societies. Finally, it promotes cultural achievement, since the feeling of power in relation to proportional resistance is the psychological incentive for self-development and cultural achievement. (shrink)

Expected utility maximization problem is one of the most useful tools in mathematical finance, decision analysis and economics. Motivated by statistical model selection, via the principle of expected utility maximization, Friedman and Sandow (J Mach Learn Res 4:257–291, 2003a) considered the model performance question from the point of view of an investor who evaluates models based on the performance of the optimal strategies that the models suggest. They interpreted their performance measures in information theoretic terms and provided new generalizations (...) of Shannon entropy and Kullback–Leibler relative entropy and called them U-entropy and U-relative entropy. In this article, a utility-based criterion for independence of two random variables is defined. Then, Markov’s inequality for probabilities is extended from the U-entropy viewpoint. Moreover, a lower bound for the U-relative entropy is obtained. Finally, a link between conditional U-entropy and conditional Renyi entropy is derived. (shrink)

In this stimulating work of political philosophy, acclaimed philosopher G. A. Cohen sets out to rescue the egalitarian thesis that in a society in which distributive justice prevails, peopleâes material prospects are roughly equal. Arguing against the Rawlsian version of a just society, Cohen demonstrates that distributive justice does not tolerate deep inequality. In the course of providing a deep and sophisticated critique of Rawlsâes theory of justice, Cohen demonstrates that questions of distributive justice arise not only for the (...) state but also for people in their daily lives. The right rules for the macro scale of public institutions and policies also apply, with suitable adjustments, to the micro level of individual decision-making. Cohen also charges Rawlsâes constructivism with systematically conflating the concept of justice with other concepts. Within the Rawlsian architectonic, justice is not distinguished either from other values or from optimal rules of social regulation. The elimination of those conflations brings justice closer to equality. (shrink)

Often, when several norms are present and may be in conflict, individuals will display a self-serving bias, privileging the norm that best serves their interests. Xiao and Bicchieri (J Econ Psychol 31(3):456–470, 2010) tested the effects of inequality on reciprocating behavior in trust games and showed that—when inequality increases—reciprocity loses its appeal. They hypothesized that self-serving biases in choosing to privilege a particular social norm occur when the choice of that norm is publicly justifiable as reasonable, even if (...) not optimal for one of the parties. In line with the literature on motivated reasoning, this justification should find some degree of support among third parties. The results of our experimental survey of third parties support the hypothesis that biases are not always unilateral selfish assessments. Instead, they occur when the choice to favor a particular norm is supported by a shared sense that it is a reasonable and justifiable choice. (shrink)

When someone hosts a party, when governments choose an aid program, or when assistive robots decide what meal to serve to a family, decision‐makers must determine how to help even when their recipients have very different preferences. Which combination of people’s desires should a decision‐maker serve? To provide a potential answer, we turned to psychology: What do people think is best when multiple people have different utilities over options? We developed a quantitative model of what people consider desirable behavior, characterizing (...) participants’ preferences by inferring which combination of “metrics” (maximax, maxsum, maximin, or inequality aversion [IA]) best explained participants’ decisions in a drink‐choosing task. We found that participants’ behavior was best described by the maximin metric, describing the desire to maximize the happiness of the worst‐off person, though participant behavior was also consistent with maximizing group utility (the maxsum metric) and the IA metric to a lesser extent. Participant behavior was consistent across variation in the agents involved and tended to become more maxsum‐oriented when participants were told they were players in the task (Experiment 1). In later experiments, participants maintained maximin behavior across multi‐step tasks rather than shortsightedly focusing on the individual steps therein (Experiment 2, Experiment 3). By repeatedly asking participants what choices they would hope for in an optimal, just decision‐maker, and carefully disambiguating which quantitative metrics describe these nuanced choices, we help constrain the space of what behavior we desire in leaders, artificial intelligence systems helping decision‐makers, and the assistive robots and decision‐makers of the future.

Psychodynamic theory and practice are often misunderstood as appropriate only for the worried well or for those whose problems are minimal or routine. Nothing could be further from the truth. This book shows how psychodynamically informed, clinically based social care is essential to working with individuals whose problems are both psychological and social. Each chapter addresses populations struggling with structural inequities, such as racism, classism, and discrimination based on immigrant status, language differences, disability, and sexual orientation. The authors explain how (...) to provide psychodynamically informed assessment and practice when working with those suffering from mental illness, addiction, homelessness, and cognitive, visual, or auditory impairments, as well as people in prisons, in orphanages, and on child welfare. The volume supports the idea that becoming aware of ourselves helps us understand ourselves: a key approach for helping clients contain and name their feelings, deal with desire and conflict, achieve self-regulation and self-esteem, and alter attachment styles toward greater agency and empowerment. Yet autonomy and empowerment are not birthrights; they are capacities that must be fostered under optimal clinical conditions. This collection uses concepts derived from drive theory, ego psychology, object relations, trauma theory, attachment theory, self psychology, relational theories, and intersubjectivity in clinical work with vulnerable and oppressed populations. Contributors are experienced practitioners whose work with vulnerable populations has enabled them to elicit and find common humanity with their clients. The authors consistently convey respect for the considerable strength and resilience of the populations with whom they work. Emphasizing both the inner and social structural lives of client and clinician and their interacting social identities, this anthology uniquely realizes the complexity of clinical practice with diverse populations.

Before the 2007–2008 global financial crisis, the vast majority of social scientists were not paying much attention to the politics of central banking, despite the fact that, since their creation, central banks have been pivotal institutions between private financial institutions and public authorities (Singleton, 2010). During the past decades, central banks acquired considerable independence from public officials under the Central Bank Independence (CBI) template (McNamara, 2002). Governments justified their decisions to delegate monetary competences by relying on a narrow conception of (...) monetary policy, in which central bankers should only seek to control inflation and ignore the implications of their policies on other economic issues such as financial stability or wealth inequalities (Issing et al., 2001; Marcussen, 2009). Heterodox economists and critical political economists opposed this view by declaring that monetary policy is fundamentally political as it deals with complicated policy trade-offs, which generates winners and losers (Epstein & Gintis, 1995; Forder, 2005). However, until 2007, their concerns were very marginal and remained at the fringes of the political debate. The vast majority of policy-makers, economists, and central bankers themselves agreed on the fact that the CBI template was the optimal institutional arrangement between fiscal and monetary authorities.

Recommender systems are recently developed computer-assisted tools that support social and informational needs of various communities and help users exploit huge amounts of data for making optimal decisions. In this study, we present a new recommender system for assessment and risk prediction in child welfare institutions in Israel. The system exploits a large diachronic repository of manually completed questionnaires on functioning of welfare institutions and proposes two different rule-based computational models. The system accepts users’ requests via a simple graphical (...) interface, calculates the institutions’ profiles according to user preferences, and presents assessment scores, trends and comparative analyses of the corresponding data using assorted visual aids. Based on the analysis, the system offers three different strategies for objective assessment of the institutions’ functioning and risks. Qualitative and quantitative evaluation of the system’s effectiveness and accuracy demonstrates that it substantially improves the assessment process of a welfare institution. Moreover, it provides an effective tool for objective large-scale analysis of the institution’s overall state and trends, which were previously based primarily on the institution supervisors’ subjective judgment and intuition. In addition, the proposed recommender system has great practical and social impact as it may help identify and avert potential problems, malfunctions, flaws, risks and even tragic incidents in child welfare institutions, as well as increase their overall functioning levels. As a result, as a long-term social implication, the system may also help reduce inequality and social gaps in the Israeli society. (shrink)

Many scholars have suggested that Aristotle’s famous aphorism ‘treat equals equally, unequals unequally’ is a formal, and thus impractical, theory of equality. This dissertation aims to criticise the popular view that Aristotle’s theory of equality is purely formal and to develop and defend an interpretation which will pay attention to the substantive elements. The first chapter argues that Aristotle provides us with a spectrum from formal to substantive equality. At the formal end, we have the abstract principles of formal fairness (...) and proportionality, while at the substantive end we can find information for the designation of the appropriate variable of comparison between people or treatments in various domains of social interaction. The second chapter argues for an account of commensurability based on Ph. VII.4. I claim that, in any comparison, the term ‘equal’ should be predicated synonymously of the people or treatment compared, while at the same time they should not admit to difference in species; such an account, I suggest, is also compatible with Aristotle’s theory of economic value in EN V.5. The third chapter presents the Aristotelian account of equality in distributions. I focus on Aristotle’s theory of political distribution in Pol. III, where he puts forward two distinct criteria: political capacity and contribution to the polis. I also examine Aristotle’s moderate suggestion for equalisation of property by the means of public property and taxation. The fourth chapter criticises the popular line that Aristotle holds an inconsistent theory of corrective justice, because in EN V.4 he suggests that people should be treated as equal before the law, while in the first lines of EN V.5 he allows for hierarchical considerations. I eliminate this apparent inconsistency by claiming that the former deals with the compensatory, while the latter with the punitive element of corrective justice. The fifth chapter explores the role of equality within the private domain, mainly in the household and in various types of friendship. I propose that Aristotle offers two types of superiority, one based on actuality and a second based on function, which are not mutually exclusive. To summarise, by examining Aristotle’s responses to various problems about equality and hierarchy I conclude that although he possesses the theoretical tools to argue for ‘inalienable’ metaphysical equality of human beings which will make equality an individual entitlement or right, based on his principle of individuation in Metaph. Z.8, he prefers not to utilise this thesis for political purposes. Instead, he reduces equality to justice (inequality is unjust, since it violates principle of formal fairness which is fundamental for justice) and a set of pragmatical considerations (e.g. concord and the optimal outcome for the polis). He prefers to argue that equality or hierarchy of people or treatments is related to, and defined by, the particular institution that we examine. (shrink)

According to the sufficiency principle, distributive justice requires that everyone have some sufficient level of resources or well-being, but inequalities above this threshold have no moral significance. This paper defends a version of the sufficiency principle as the appropriate response to moral uncertainty about distributive justice. Assuming that the appropriate response to moral uncertainty is to maximize expected choiceworthiness, and given a reasonable distribution of credence in some familiar views about distributive justice, a version of the sufficiency principle strikes the (...) optimal balance between the competing moral risks posed by implementing these views. In particular, it avoids the moral risk posed by views like Nozick’s libertarianism, which forbid redistributive taxation even for the sake of helping to provide for people’s basic needs: failing to do the latter, if it turns out that justice does require it, would be very morally wrong. This “uncertainty argument” has the advantage of minimizing reliance on controversial intuitions about distributive justice, helps to specifying a non-arbitrary threshold for sufficiency, and shows that the substantive moral implications of moral uncertainty are not limited to high-stakes applied ethics issues such as abortion and vegetarianism but instead extend to an issue at the heart of political philosophy.

In lieu of an abstract, here is a brief excerpt of the content:Guest Editors' NoteKevin Taylor (bio) and Johnathan Flowers (bio)Welcome to this special fall 2021 issue of Education & Culture. we are pleased to bring you the second installment of this special three-part issue on Deweyan approaches to contemporary issues at the intersection of data and technology.In his extensive writings on philosophy and technology, Luciano Floridi has argued that "the time has come to translate environmental ethics into terms of (...) infosphere and informational entities, for the land we now inhabit is not just the earth."1 This may be appropriate from a Deweyan perspective as Dewey's approach to aesthetic experience focuses on the living organism within its environment and we have become digital humans in digital environments. Our digital world feels unstable because it is in constant change, but Dewey reminds us that "all interactions that effect stability and order in the whirling flux of change are rhythms. There is ebb and flow, systole and diastole: ordered change."2 The rhythms of our digital world pervade all experience in what he termed "doing and undergoing." We are swimming in a sea of data and leaving behind what investigative reporter Julia Angwin terms data pollution.3 But in the data-driven world, that data pollution is collected, analyzed, and monetized by big data tech firms in a kind of societal harm that threatens digital democracy.Whereas part one saw contributions from five scholars throwing curriculum and technology into sharp relief, this issue asks questions such as "Where ought we to begin?", "What does feminist pragmatism have to tell us about the pandemic and online teaching and learning?", and "Do the aims and means of data and technology align with human experience?"John Machielsen's "Responsible Imagineering: John Dewey's Pluralistic Ethics and Technological Innovation" seems like a good place to begin. Machielsen argues for placing Dewey's ethics at the starting point from which technological innovation can flourish. Driven by Deweyan concepts of intelligence, education, and imagination, Machielsen explores, among other themes, socially disruptive technology from the perspective of pragmatists who constantly reconstruct concepts and values through the process of Deweyan inquiry. Human beings are imaginative and plastic with regard to problem solving, and what is needed here is to keep the barriers between technology and everyday life porous so that we do not risk compartmentalizing them as distinctly different realms.In the next two essays, we turn our attention to the growing concerns surrounding intelligent technology in online educational environments. Great strides have been made in the field of artificial intelligence, and intelligent technology has inserted itself into various aspects of data and technology, such as machine learning that creates personalized learning paths for students. Whether these technologies fall under the [End Page 1] category of algorithms, machine learning, or artificial intelligence, they raise questions about their potential impact on teaching and learning.Olivier Del Fabbro is also suspicious of the current state of intelligent technology in his article, "How to Teach Machines in Artificial Intelligence: Technical Education in John Dewey, Gilbert Simondon, and Machine Learning." Citing the Google machine learning model that classified African Americans as gorillas, Del Fabbro utilizes Dewey and Gilbert Simondon to argue that the human–machine relationship is still immature and at risk of creating an alienated situation out of undesirable bad habits. Intelligent technology requires constant care by engineers and programmers to form good habits and adapt to social life if their aims are to align with Deweyan pedagogy.As Del Fabbro focuses on intelligent technology, the human dimension of online learning comes under scrutiny in two articles that adopt feminist pragmatist methods. Krissah Marga B. Taganas's article, "Feminist-Pragmatist Perspectives on Online Education: Challenging and Changing Online Educational Conversation," rightfully acknowledges how the pandemic has magnified existing inequalities in society. The rapid migration to online learning was necessarily expedited in the face of uncertainties surrounding public health, but how do educators migrate classes that were not designed with online learning in mind to begin with? Dewey emphasized schools as sites and tools for change, but how does online education provide an optimal social environment for learning? Taganas utilizes feminist pragmatism as an important philosophical resource to... (shrink)

According to Zurek, the emergence of a classical world from a quantum substrate could result from a long selection process that privileges the classical bases according to a principle of optimal information. We investigate the consequences of this principle in a simple case, when the system and the environment are two interacting scalar particles supposedly in a pure state. We show that then the classical regime corresponds to a situation for which the entanglement between the particles (the system and (...) the environment) disappears. We describe in which circumstances this factorisability condition is fulfilled, in the case that the particles interact via position-dependent potentials, and also describe in appendix the tools necessary for understanding our results (entanglement, Bell inequalities and so on).

Certified nursing assistants (CNAs) provide the majority of direct care to nursing home residents in the United States and, therefore, are keys to ensuring optimal health outcomes for this frail older adult population. These diverse direct care workers, however, are often not recognized for their important contributions to older adult care and are subjected to poor working conditions. It is probable that social‐based discrimination lies at the core of poor treatment toward CNAs. This review uses perspectives from critical social (...) theory to explore the phenomenon of social‐based discrimination toward CNAs that may originate from social order, power, and culture. Understanding manifestations of social‐based discrimination in nursing homes is critical to creating solutions for severe disparity problems among perceived lower‐class workers and subsequently improving resident care delivery.

We consider the complexity (in terms of the arithmetical hierarchy) of the various quantifier levels of the diagram of a computably presented metric structure. As the truth value of a sentence of continuous logic may be any real in [0, 1], we introduce two kinds of diagrams at each level: the closed diagram, which encapsulates weak inequalities of the form $$\phi ^\mathcal {M}\le r$$, and the open diagram, which encapsulates strict inequalities of the form $$\phi ^\mathcal {M}< r$$. We show (...) that the closed and open $$\Sigma _N$$ diagrams are $$\Pi ^0_{N+1}$$ and $$\Sigma ^0_N$$ respectively, and that the closed and open $$\Pi _N$$ diagrams are $$\Pi ^0_N$$ and $$\Sigma ^0_{N + 1}$$ respectively. We then introduce effective infinitary formulas of continuous logic and extend our results to the hyperarithmetical hierarchy. Finally, we demonstrate that our results are optimal. (shrink)

A poset is well‐partially ordered (WPO) if all its linear extensions are well orders; the supremum of ordered types of these linear extensions is the length, of p. We prove that if the vertex set X is infinite, of cardinality κ, and the ordering ⩽ is the intersection of finitely many well partial orderings of X,, then, letting, with, denote the euclidian division by κ (seen as an initial ordinal) of the length of each corresponding poset: where denotes the least (...) initial ordinal greater than the ordinal. This inequality is optimal. This result answers questions of Forster. (shrink)

American Indian/Alaska Native (AI/AN) populations in the United States continue to experience overall health inequity, despite significant improvement in health status for nearly all other racial‐ethnic groups over the past 30 years. Nurses comprise the bulk of healthcare providers in the U.S. and are in an optimal position to improve AI/AN health by transforming both nursing education and practice. This potential is dependent, however, on nurses’ ability to recognize the distinct historical and political conditions through which AI/AN health inequities (...) have been produced and sustained. Nurse providers, educators, and leaders must in turn recognize how the sustained conditions of marginalization and expropriation that underpin current AI/AN health inequities continue to shape contemporary AI/AN health outcomes. This manuscript builds upon the extant literature of AI/AN historical health policy and utilizes decolonial theorizations of nursing and a cultural safety framework to propose a series of immediately actionable steps for nursing intervention into AI/AN health inequity. Ultimately, we suggest that it is crucial for nurses to collaborate with AI/AN individuals and communities across educational and clinical settings to further refine these approaches in alignment with the disciplinary obligation of promoting social justice within healthcare.

The purpose of the article is to draw comparisons between the major normative rules of distributive justice. This comparison is based on a kind of distribution of goods which is sometimes called the problem of pure distribution, i.e. the distribution of a homogeneous, infinitely distributable good in a situation when claims of different persons on the distributed good were in no way differentiated. This problem is defined against the background of typology of problems of goods distribution. Normative rules of distributive (...) Justice are defined formally as social welfare functionals. Eight rules of justice are distinguished: the rule of the utilitarian, Rawls’s maximin rule, Rawls’s lexicographical maximin rule, the maximax rule of the conservatives, the rule of lexicographical maximax of the conservatives, Nash’s rule, and two rules advanced by egalitarianists which differ by the meaning attributed to equality of distribution. Premises underlying the construction of these rules of justice and which indicate the measurement of preferences and possibilities of interpersonal comparisons are discussed. The same justice rules are also presented graphically. The method of the comparison amounts to examining if a certain set of ethical postulates is fulfilled by the rules under consideration. Several ethical postulates concerning the distribution of goods are formulated. Some of them define conditions any method of evaluating inequality of distribution of goods should fulfil. The remaining postulates involve more general requirements put to methods of making social decisions. Theorems about the fulfilment or nonfulfilment by individual rules of distributive justice of the considered ethical postulates are presented in a recapitulating table. The author demonstrates that almost a1l justice rules fulfil general postulates put to methods of social decision making. Nash’s rule and the two rules of the egalitarians are the exceptions, as they do not fulfil the postulate of separability with respect to unconcerned individuals. Besides, the two rules of the egalitarians do not fulfil the Pareto optimality principle. Significant differences between rules of distributive justice become manifest only when you compare way they fulfil ethical postulates concerning the manner of evaluating the inequality of the distribution. With regard to this set of postulates, they can be arranged along a definite continuum, with Rawls’s lexicographical maximin — the radical egalitarian rule, and the lexicographical maximax of the conservatives – the radical conservative rule as the extreme points of this continuum.

Expected utility maximization problem is one of the most useful tools in mathematical finance, decision analysis and economics. Motivated by statistical model selection, via the principle of expected utility maximization, Friedman and Sandow (J Mach Learn Res 4:257–291, 2003a) considered the model performance question from the point of view of an investor who evaluates models based on the performance of the optimal strategies that the models suggest. They interpreted their performance measures in information theoretic terms and provided new generalizations (...) of Shannon entropy and Kullback–Leibler relative entropy and called them U-entropy and U-relative entropy. In this article, a utility-based criterion for independence of two random variables is defined. Then, Markov’s inequality for probabilities is extended from the U-entropy viewpoint. Moreover, a lower bound for the U-relative entropy is obtained. Finally, a link between conditional U-entropy and conditional Renyi entropy is derived. (shrink)

The increasing use of pharmacotherapy raises specific ethical concerns for psychologists working with vulnerable populations. Due to a shortage of trained specialists, professionals without training in mental health, such as primary care providers, are increasingly prescribing and monitoring psychotropic medications. Vulnerable populations face additional barriers to mental health treatment and are at heightened risk when these factors intersect. Hence, these patients experience unique barriers to receiving optimal psychopharmacological care and are differentially vulnerable to deleterious outcomes associated with misdiagnosis and (...) overmedication. Taken together, these factors fuel inequities in the access, quality, and utilization of mental health care. Psychologists working with these patients are ethically mandated to protect patients from harm and ensure equitable care across patient populations. Specifically, psychologists must respond to the dilemma of how to effectively treat patients within these vulnerable populations who have been misdiagnosed or poorly medicated while remaining within the bounds of their competence. This article recommends pathways to address these dilemmas through education, training, research, and advocacy. (shrink)

The infant mortality rate in Liberia is 50 times higher than it is in Sweden, whilst a child born in Japan has a life expectancy at birth of more than double that of one born in Zambia. 1 And within countries, we see differences which are nearly as great. For example, if you were in the USA and travelled the short journey from the poorer parts of Washington to Montgomery County Maryland, you would find that ‘for each mile travelled life (...) expectancy rises about a year and a half. There is a twenty-year gap between poor blacks at one end of the journey and rich whites at the other’. (Marmot, 2004, p.2). There are two types of questions which it is important to ask about inequalities in health such as these. The first are social scientific questions about the extent of inequalities in health and the factors which are causally responsible for these inequalities. Examples of social scientific questions to ask might be: how do infant mortality rates in the UK differ according to social class? What is the difference in life expectancy between Japanese who emigrate to the US and those who remain in Japan? Why do civil servants in higher ranked jobs tend to live longer than civil servants in lower ranked jobs? The second type are normative questions about the reasons we have to care about inequalities in health. Important normative questions to answer are: which inequalities in health should we care about (all inequalities or merely some of them)? When is an inequality in health unjust? How should we weigh our concern for equality in health against other factors such as maximising the.. (shrink)

In this book Larry Temkin examines the concepts of equality and inequality, and addresses one particular question in depth: how can we judge between different sorts of inequality? When is one inequality worse than another? Temkin shows that there are many different factors underlying and influencing our egalitarian judgments and that the notion of inequality is surprisingly complex. He looks at inequality as applied to individuals and to groups, and at the standard measures of (...) class='Hi'>inequality employed by economists and others, and considers whether inequality matters more in a poor society than a rich one. The arguments of non-egalitarians are also examined. Temkin's book presents a new way of thinking about equality and inequality which challenges the assumptions of philosophers, welfare economists, and others concerned with these notions on a practical as well as a theoretical level.

Temkin presents a new way of thinking about equality and inequality that challenges the assumptions of philosophers, welfare economists, and others, and has significant implications on both a practical and theoretical level.

In this article, the author addresses two feminist issues: first, how to conceptualize intersectionality, the mutual reproduction of class, gender, and racial relations of inequality, and second, how to identify barriers to creating equality in work organizations. She develops one answer to both issues, suggesting the idea of “inequality regimes” as an analytic approach to understanding the creation of inequalities in work organizations. Inequality regimes are the interlocked practices and processes that result in continuing inequalities in all (...) work organizations. Work organizations are critical locations for the investigation of the continuous creation of complex inequalities because much societal inequality originates in such organizations. Work organizations are also the target for many attempts to alter patterns of inequality: The study of change efforts and the oppositions they engender are often opportunities to observe frequently invisible aspects of the reproduction of inequalities. The concept of inequality regimes may be useful in analyzing organizational change projects to better understand why these projects so often fail and why they succeed when this occurs. (shrink)

What constitutes enjoyment of life? Optimal Experience: Psychological Studies of Flow in Consciousness offers a comprehensive survey of theoretical and empirical investigations of the "flow" experience, a desirable or optimal state of consciousness that enhances a person's psychic state. "Flow" can be said to occur when people are able to meet the challenges of their environment with appropriate skills, and accordingly feel a sense of well-being, a sense of mastery, and a heightened sense of self-esteem. The authors show (...) the diverse contexts and circumstances in which flow is reported in different cultures (e.g. Japan, Korea, Australia, Italy), and describe its positive emotional impacts. They reflect on the concept of flow vis-à-vis modern social structures, historical phenomena, and evolutionary biocultural selection. The ways in which the ability to experience flow affects work satisfaction, academic success, and the overall quality of life are suggested; and the childrearing practices that result in the ability to derive enjoyment from life, considered.

The Enhanced Indispensability Argument appeals to the existence of Mathematical Explanations of Physical Phenomena to justify mathematical Platonism, following the principle of Inference to the Best Explanation. In this paper, I examine one example of a MEPP—the explanation of the 13-year and 17-year life cycle of magicicadas—and argue that this case cannot be used defend the EIA. I then generalize my analysis of the cicada case to other MEPPs, and show that these explanations rely on what I will call ‘ (...) class='Hi'>optimal representations’, which are representations that capture all that is relevant to explain a physical phenomenon at a specified level of description. In the end, because the role of mathematics in MEPPs is ultimately representational, they cannot be used to support mathematical Platonism. I finish the paper by addressing the claim, advanced by many EIA defendants, that quantification over mathematical objects results in explanations that have more theoretical virtues, especially that they are more general and modally stronger than alternative explanations. I will show that the EIA cannot be successfully defended by appealing to these notions. (shrink)

In a recent paper, Potochnik (Biol Philos 24(2):183–197, 2009) analyses some uses of optimality modelling in light of the anti-adaptationism criticism. She distinguishes two broad classes of such uses (weak and strong) on the basis of assumptions held by biologists about the role and the importance of natural selection. This is an interesting proposal that could help in the epistemological characterisation of some biological practices. However, Potochnik’s distinction also rests on the assumption that all optimality modelling represent the selection dynamic (...) involved in the system of phenomena being considered. Since this assumption does not hold for models belonging to optimal foraging theory (OFT)—one of behavioural ecology’s important modelling traditions—Potochnik’s proposal has to be critically reappraised. In this paper, we briefly discuss what is optimality modelling and what it means for a model to represent a dynamic of selection or of evolution. Then, we demonstrate that OFT modelling is unable to represent either past or contemporary selection dynamics. In order to make this point, we carefully delineate the theory’s rationale. This allows us to identify and analyse the assumptions on which the theory is built, and to circumscribe precisely the role that natural selection plays in it. Next, we show that the distinction of weak and strong uses of optimality modelling is seriously weakened when OFT modelling is taken into account. More precisely, the distinction is either irrelevant (if the assumption that selection dynamics are represented in all optimality modelling is held) or of a modest utility (if the assumption is dropped). However, we suggest that Potochnik’s original proposal could be saved, and that it even constitutes a tool to appraise the marks left in the literature by the evolution of optimality modelling practices in the last four decades, provided that it is made into a tripartite distinction.
