This paper presents a procedure to select equitable stable allocations in two-sided matching markets without side payments. The Equitable set is computed using the Equitable algorithm. The algorithm limits the set of options available for each agent throughout the procedure. The stable matchings selected are generally not extreme, form a lattice and satisfy the condition of being “Ralwsian” in each partition of the market. The Equitable algorithm can also be used to select a particular matching from the (...) Equitable Set favoring particular agents independent of the side of the market to which they belong. (shrink)

We consider two-sided matching markets with couples. First, we extend a result by Klaus and Klijn (J Econ Theory 21: 75–106, 2005, Theorem 3.3) and show that for any weakly responsive couples market, there always exists a “double stable” matching, i.e., a matching that is stable for the couples market and for any associated singles market. Second, we show that for weakly responsive couples markets, the associated stable correspondence is (Maskin) monotonic and Nash implementable. In (...) contrast, the correspondence that assigns all double stable matchings is neither monotonic nor Nash implementable. (shrink)

This paper studies welfare tradeoffs in two-sided, one-to-one matching markets. We begin by providing theoretical upper bounds on a utilitarian price of stability, and show that these bounds vary with the composition of participants’ ordinal preference lists. We then turn to simulation experiments to describe how changes in basic characteristics of agents’ preferences can increase or decrease the average price of stability as measured by both utilitarian and Rawlsian welfare criteria. Our results indicate that markets featuring moderate (...) degrees of correlation and positive intercorrelation in the preferences of participants exhibit the steepest tradeoffs between stability and utilitarian welfare and between stability and Rawlsian welfare.

Technology plays a very important role in virtually all areas, and has become an inseparable part of the industry. Currently, industry and technology are at a high point of development and research, but there is an ever increasing gap between the market needs and the skills that universities deliver to students. There is an increasing need for consolidation between university curricula and the industry needs in terms of qualifications. In this paper we will present a description of the current state (...) of the labor market in the field of technology, including the needs that arise in improving the existing curricula of the Universities. We review the different technologies that can be used, in order to automatically gather information about the market needs in terms of job offers, and how they can be compared against University curricula. We will also present the latest achievements on these methods, and the suggestions that the researchers provide. (shrink)

The study of matching degree between energy equipment manufacturing and market demand is crucial for energy enterprises to adjust business strategies, expand market share, and develop sustainably. Considering that the current electricity market evaluation indicators are rarely selected from a global perspective and a single evaluation method may lead to one-sided results, this article takes the technology and equipment related to electric energy as the research object and selects six indicators, including technical standards, qualification certification, export methods, after-sales service, (...) market concentration, and product concentration. By analyzing the supply and demand characteristics of major global regional markets and the situation of Chinese power enterprises in these markets, we propose matching model cluster including osculating value method, rank-sum ratio method, ideal point method, entropy value method, and efficacy coefficient method to conduct the matching degree study. The results show that the overall market matching degree of Chinese power companies is good, especially in Southeast Asia, Central Asia, and Africa. For markets with a low degree of matching, we analyze the reasons based on the matching indicators values to provide companies with corresponding strategies and recommendations. (shrink)

In Pelota matches, bets are made between viewers through a middleman who receives 16% of the finally paid amount. In this paper, a description of the way bets are made and an explanation of the existence of those markets are presented. Taking betting markets as a simplified analogy for financial markets we have searched for the explanation in a world where both sides of the market are not different in believes and preferences. We find that for a (...) bet to exist when bettors are rank dependent expected utility maximizers, they have to be optimistic. Taking observations from actually made bets a preliminary analysis about the biases of those markets is presented. (shrink)

The paper defines a measure on the set of stable matchings in the marriage problem. This measure is based on the minimization of the envy difference between the sets of men and women, while preserving stability and selects stable matchings with the least conflict of interest between both groups of agents. The solution concept proposed is called Sex-equal Matching (SEM) and the paper also provides an algorithm to compute the set of SEM.

As it has become more and more urgent to solve the problems of environmental protection, we consider it necessary to conduct multilevel studies to examine the impact of business strategy on both employees’ and firms’ performances in environmental protection. Synthesizing the perspectives of strategic orientation, corporate strategy, and firm performance, we propose a comprehensive theoretical model linking market orientation and environmental performance. Based on a survey of 134 matched chief executive officers, senior marketing managers and frontline workers from Chinese firms, (...) we found that market orientation positively affects environmental strategy which, in turn, influences both environmental product quality and employees’ environmental involvement. These latter two variables consequently have a positive influence on environmental performance. At the same time, environmental commitment moderates the link between market orientation and environmental strategy. (shrink)

The move from open outcry to electronic trading added another responsibility to futures exchanges—that of matching orders between buyers and sellers. Matching systems can affect the level and speed of price discovery, the distribution of revenue, as well as the level of price efficiency of a given market. Whether the matching system is procedurally fair is another important consideration. I argue that while FIFO (First In First Out) is a fair procedure in principle and is perceived as (...) the default matching system, it is not a fair procedure in practice. Likewise, while pro rata is a fair procedure in principle, it is not so in practice. Nevertheless, both FIFO and pro rata are relics of an open outcry system. Instead, I propose an alternative approach to matching systems that builds on the strengths of electronic trading—the ability to randomize in real time. I introduce random selection for service (RSS) as a matching system that is procedurally fair both in principle and in practice. (shrink)

We examine whether investors value the disclosure of first-time standalone corporate social responsibility reports, and whether market valuations differ between government-controlled and privately controlled firms. Using a matched sample of Chinese publicly listed firms, we find that CSR initiators have higher market valuations than matched CSR non-initiators, and CSR initiators controlled by the central and local governments have lower market valuations than CSR non-initiators and CSR initiators controlled by private shareholders. Additional analyses demonstrate that CSR initiators with high CSR reporting (...) quality and perceived credibility have higher market valuations than CSR initiators with low CSR reporting quality and medium or low perceived credibility of CSR reporting. We do not find convincing evidence that CSR mandate, litigation risk, and prior stock returns affect market reactions to CSR reporting. Overall, we find that the market values standalone CSR reports, and that CSR reporting quality and perceived credibility are important factors in market valuation. (shrink)

Özkal-Sanver (Theory Decis 59:193–205, 2005) studies stability and efficiency of partitions of agents in two-sided matching markets in which agents can form partitions by individual moves only, and a matching rule determines the matching in each coalition in a partition. In this study, we present the relationship between stability and efficiency of partitions that is analyzed for several matching rules and under various membership property rights codes, now allowing coalitional moves.

The fall of the former Soviet Union and the opening of the countries of Eastern Europe has prompted examination of why central planning failed, why capitalism with all its faults is succeeding, and what actions and institutions are necessary to move command economies toward successful, sustainable market economic systems. As they privatize State Owned Enterprises (SOE's) expectations are that the companies will function with the success experienced by western companies. Governments hope to derive tax revenue from company profits and expect (...) companies to provide jobs. Effecting the change is, however, far greater than changing the name plate on the door. Transition success will hinge upon institutional and infrastructure changes that need to be wide-spread. The ethical quagmire is that without changes in the infrastructure of the command economy system private enterprise is doomed to fail. Governments will then be deprived of the anticipated revenue streams emanating from businesses. Governments may then not be able to fulfill the economic and social expectations of their citizens. This would be not only counter-productive for businesses and government but also confusing and bewildering to the general populous. This paper explores structural impediments in transition economies and discusses how each blocks and distorts the formation of a true market economy. (shrink)

The labor market is an area with diverse data structures and multiple applications, such as matching job seekers with the right training or job. For this reason, the multilingual classification of European Skills, Competences, Qualifications and Occupations (ESCO) is a good example of the central role of ontologies in this area. However, ESCO cannot provide all the details of local labor market needs and does not provide links to other hierarchies of competences. For example, other taxonomies of occupations and (...) skills are widely used in German-speaking countries, but they are not in a state where they are easily accessible for interoperability and reasoning. In this paper, we present a first version of a German Labor Market Ontology (GLMO) that uses ESCO as a top-level ontology for the target domain. This makes it highly interoperable and comparable to existing ontologies by providing details for the regional structures in German-speaking countries. In addition, we present a detailed evaluation of the provided data and applications, as well as an extensive discussion of future work. (shrink)

The prevailing model for encouraging innovation based on patents and market-oriented raises at least two economic and ethical issues: it imposes barriers on individuals and developing countries governments' access to medicines by defining prices that do not match their income, and the unavailability of new or appropriate products to address the health problems of these populations. In the last decade, this scenario has undergone some changes due to the emergence of new actors, the contribution of aid resources, the introduction to (...) the market of new products against neglected diseases, the development of new governmental healthcare policies and research programs, etc. One example of such initiatives is the Fixed-Dose Artesunate Combination Therapy (FACT) project consortium, which brought together institutions with different natures from both the North and the South, for the development of two antimalarial fixed-dose combinations recommended by the WHO – artesunate-amodiaquine (ASAQ) and artesunate-mefloquine (ASMQ). This paper proposes to describe and analyze the ASMQ consortium, which is the result of a new pharmaceutical development approach, based on a different paradigm – needs-driven instead of market-driven –, collaborative, with strategic participation of institutions from the South, funded by alternative resources (public and philanthropic). Thus, it represents an interesting object of study for bioethical debates on intellectual property and innovation, and its analysis is justified in light of the current debate on ways of stimulating needs-driven pharmaceutical innovation.

We systematically examined the content of the websites of 46 agencies that buy and sell human eggs to understand how they market themselves to both donors and recipients. We found that these websites use marketing techniques that obscure the realities of egg donation, presenting egg donation as a mutually beneficial and fulfilling experience. Sites emphasize egg donors' emotional fulfillment and address recipients' anxieties by stressing the ability to find the perfect “fit” or “match”, suiting recipients’“preferences”/“desires”, and even designing/customizing a child. (...) Agencies attempt to create a sense of connection between the recipients and donors by reporting donors' personal characteristics — e.g., interests/hobbies, traits, mood/temperament, and self-reported childhood behavior/memories. Sites present donors as caring/generous and smart/successful/beautiful. These data, the first to examine several key aspects of egg donation agency websites, reveal critical aspects of how these companies communicate to prospective donors and recipients, raising several ethical concerns. Websites frame information in ways that may bias consumers, making emotional appeals that may distract from appropriate risk/benefit assessments and obscure the ethical challenges of egg donation. These data highlight needs for improved practices, adherence to guidelines, and consideration of enhanced guidelines or policy. (shrink)

The theory of competition has held a central place in economic analysis since Adam Smith. This book, written by one of the most distinguished of contemporary economic theorists, reports on a major research program to provide strategic foundations for the theory of perfect competition. Beginning with a concise survey of how the theory of competition has evolved, Gale makes extensive and rigorous use of dynamic matching and bargaining models to provide a more complete description of how a competitive equlibrium (...) is achieved. Whereas economists have made use of a macroscopic description of markets in which certain behavioral characteristics, such as price-taking behavior, are taken for granted, Gale uses game theory to re-evaluate this assumption, beginning with individual agents and modelling their strategic interaction. A strategic foundation for competitive equilibrium shows how such interaction leads to competitive, price-taking behavior. Essential reading for graduate courses in game theory and general equilibrium. (shrink)

This article focuses on the relationship of employer behaviour to labour market inequalities. Matched employer-employee data are casting an important new light on how variation in wage setting practices across firms can affect the structure of earnings and earnings mobility. It shows that very different wages are paid to equivalent labour across and within firms. It also argues that policies targeting firm selection of workers may affect inequality as much as policies of training and education.

Firm–employee relationships are dependent on the wider societal context and on the role business plays in society. Changes in institutional arrangements in society affect the perceived responsibilities of firms to their personnel. In this study, we examine mass media discussions about firm–employee relationships from a social responsibility perspective via a longitudinal study in Romanian society. Our analysis indicates how the expected responsibilities of firms towards employees have altered with the changing role of firms in society since the early 1990s. These (...) transformations correspond to the ideological developments, from communist to market-based thinking, which have taken place in post-communist Eastern Europe. More specifically, our study shows how the diminishing expectations of corporate social responsibility (CSR) are linked in mass media to increasingly important talk of human resource management (HRM). HRM is a modern business approach believed to address personnel needs and organisational objectives simultaneously. The congruency of goals in HRM may mistakenly lead to the conclusion that organisations are inherently responsible toward their personnel. We argue that this may not necessarily be the case. HRM, matching well the new free-market ideology in post-communist Eastern Europe, was eagerly embraced in that it defined firm–personnel relationships. In this study, we question whether this was an adequate theoretical perspective for Romanian firms to adopt as it lacks sufficient ethical grounding. We also call for a higher awareness concerning the role of mass media in the management literature, since its current role in constructing the ‘rightness’ and ‘wrongness’ in firm–personnel relationships is hardly considered.

We examine whether gender-diverse boards prioritize product market concerns over capital market incentives when proprietary costs are high. We argue that gender-diverse boards protect their firm’s competitive edge and maximize long-term shareholder wealth by ethically and carefully maintaining the confidentiality of proprietary information. Due to the reduced disclosure of proprietary information, firms with gender-diverse boards are likely to face more adverse selection when proprietary costs are high. However, the reduced disclosure of proprietary information enables firms with gender-diverse boards to enhance (...) and maintain their competitive edge and gain higher long-term returns. Using a matched sample of the United States-listed companies, we find that firms with gender-diverse boards, relative to similar firms with all-male boards, (1) are associated with higher adverse selection costs and (2) higher long-run stock returns when the firm faces high product market competition. Collectively, our results suggest that firms with gender-diverse boards, which initially experience higher adverse selection in a competitive environment, are rewarded with a net gain of about 10 percent of their stock price in three years. Our research contributes to the literature by highlighting the importance of board gender diversity in fostering the ethical redaction of proprietary information for proprietary cost-based motives as opposed to agency cost-based motives. Our findings have important implications for regulators, firms, and shareholders by identifying gender-diverse boards as an antecedent for the ethical redaction of proprietary information. (shrink)

We study envy-free allocations in a many-to-many matching model with contracts in which agents on one side of the market (doctors) are endowed with substitutable choice functions and agents on the other side of the market (hospitals) are endowed with responsive preferences. Envy-freeness is a weakening of stability that allows blocking contracts involving a hospital with a vacant position and a doctor that does not envy any of the doctors that the hospital currently employs. We show that the set (...) of envy-free allocations has a lattice structure. Furthermore, we define a Tarski operator on this lattice and use it to model a vacancy chain dynamic process by which, starting from any envy-free allocation, a stable one is reached. (shrink)

Employers’ access to and use of criminal records as a selection mechanism in the labor market makes it far more difficult for ex-offenders to find jobs, especially regular, well-paid jobs, than those without criminal convictions. The paper asks whether there is anything morally problematic about this practice. The aims of the paper are twofold. First, arguments based on premises of wrongful discrimination against the current, commonest use of criminal records are critically discussed. It is argued that employers do not necessarily (...) engage in morally wrongful discrimination against job applicants when they use criminal records in recruitment screening. But it is also argued that ex-offenders who apply for jobs are subject to what can be called “structural and morally wrongful discrimination” when laws allow employers to request (or directly access) a job applicant’s full criminal record. Second, preliminary proposals on how criminal records can be used by employers in a way that avoids wrongful structural discrimination of ex-offenders will be presented and critically assessed. I suggest that it should be lawful for an employer to access an applicant’s criminal records only where there is a relevant and special match or link between the crime on the records and the job being applied for and the crime is serious. This proposal is defended against two objections, one based on concerns about crime prevention and the other based on the employer’s interest in knowing whom not to hire. (shrink)

Impact investing is the fastest growing responsible investment strategy and has the potential to address many of the environmental and socio-economic challenges faced by humanity. Some scholars, however, claim that definitional ambiguity confounds impact measurement and hence reduces the attractiveness of this investment strategy. To investigate this claim, semi-structured personal interviews were conducted with 13 experienced impact investors in a large African market. Participants did not regard definitional ambiguity as a serious barrier, but found it difficult to identify and articulate (...) specific impact objectives that could match their financial return expectations. Investors called for more training and information sharing platforms. (shrink)

Alternative agricultural systems, like organic and local agriculture, are becoming increasingly important in Europe to the detriment of conventional methods. As a matter of fact, sustainable agriculture, which started as a niche sector, has been able to conquer a significant share of the European agro-food market. Institutional promotion along with increasing consumer demand has allowed for the development of different agricultural models, from the farm to the fork, with an increasing focus on the ethical issues associated with the agro-food production (...) system. For instance, the organic agriculture agro-food chain is based on four principles, namely health, ecology, fairness and care with the goal of competing in the global agro-food market while respecting the environment, livestock, producers, and consumers. Within these themes, the seed market represents an extremely complex part of the whole picture. The present paper analyses the historical evolution of the seed sector by identifying the main issues related to sustainable agricultural systems and protection of biodiversity. It follows the identification of different seed markets based on different farm types. The two aspects are then discussed and matched in order to identify the main issues characterizing the sector. A review of possible solutions to those problems, taking into account their ethics, is also provided. (shrink)

In a crisis, managers are confronted with a dilemma between their ethical responsibility to respond to victims and their fiduciary responsibility to protect shareholder value. In this study, we use a unique and comprehensive dataset of 223 non-financial crises between 1983 and 2013 to investigate how corporate apologies affect stock prices. Our empirical evidence shows that the stock price response from apologizing depends on the firm’s level of responsibility for the crisis. We find that to protect shareholder value, management needs (...) to match its formal response strategy with the degree of its responsibility for the crisis. Further, failing to match the proper response is harmful to shareholders: Both apologizing when the firm is not directly responsible for the crisis and failing to apologize when the firm is directly responsible reduce shareholder wealth. However, apologizing for a crisis when the firm is directly responsible mitigates losses to shareholder value that arise because of the crisis, as does refraining from apologizing when the firm is not directly responsible.

Interest in Aristotelianism and in virtue ethics has been growing for half a century but as yet the strengths of the study of Aristotelian ethics in politics have not been matched in economics. This ground-breaking text fills that gap. Challenging the premises of neoclassical economic theory, the contributors take issue with neoclassicism’s foundational separation of values from facts, with its treatment of preferences as given, and with its consequent refusal to reason about final ends. Contributions critically engage with aspects of (...) corporate capitalism, managerial power and neoliberal economic policy, and reflect on the recent financial crisis from the point of view of Aristotelian virtue ethics. Containing a new chapter by Alasdair MacIntyre, and deploying his arguments and conceptual scheme throughout, the book critically analyses the theoretical presuppositions and institutional reality of modern capitalism.

When organizations face the coexistence of multiple institutional logics for environmental management (e.g., maximizing market profit, protecting the environment), how do firms configure green human resource management (GHRM) practices to achieve sustainability in both environmental and market domains? Leveraging the fuzzy-set qualitative comparative analysis (fsQCA) technique, this study adopts a configurational approach to analyze the complex interdependence of GHRM practices with the underlying institutional logics for achieving firm sustainable performance. Employing a multi-source matched sample of 179 firms, the findings reveal (...) the existence of multiple configurations of institutional logics and GHRM practices that equally result in high environmental performance, market performance, or both. The analysis also identifies that firms vary in their selection between environment protection and market profit logics, and the need to match different control- or commitment-based GHRM practices to achieve high environmental and market performance.

Socialism is dead, though many of its academic proponents take no notice of its demise. With its death, private property in the means of production is not generally in dispute, and the action in political philosophy centers on the justification of the welfare state. The heart of the welfare state is social insurance programs, such as government managed and subsidized health insurance, retirement pensions, and unemployment insurance. The arguments about health insurance will arguably be among the most ferocious, difficult, and (...) important of the welfare-state debates: Ferocious, because proposals to alter government managed or subsidized health care strike at people's fears and concerns in a way matched by few other proposals. Difficult, because people can often not even conceive of a market alternative to the status quo in health insurance, and there is no real existing alternative to hold up as a model. Important, because if an intellectually solid case for market health insurance can be established, then supporters of the welfare state should be on the defensive, since social health insurance is an institution central to their vision of the just or good society.

In contrast to the conventional fund management industry with a profit-oriented logic based on risk and return, ethical and faith-based funds should follow the religious principles of their investment-style philosophy. Islamic funds should obey the theological teachings of the primary sources of Islam, the Quran and Sunnah, as stakeholders expect these religious teachings to influence the investment decisions of fund managers. In practice, Islamic fund managers use Accounting and Auditing Organization for Islamic Financial Institutions ’s screening criteria, based on secondary (...) sources of Islam, which allow investments that are only partially halal to be included in their portfolios. This study finds that a more religious logic in screening practices, although impairing diversification, does not necessarily harm performance. Thus, Islamic investment funds, and the wider ethical fund management industry, should, and could, adopt stricter screening criteria that match their investment mandates and bring more ethical business practices to the industry.

The paper examines the ethics of electronic monitoring for advertising purposes and the implications for Internet user privacy using as a backdrop DoubleClick Incs recent controversy over matching previously anonymous user profiles with personally identifiable information. It explores various ethical theories that are applicable to understand privacy issues in electronic monitoring. It is argued that, despite the fact that electronic monitoring always constitutes an invasion of privacy, it can still be ethically justified on both Utilitarian and Kantian grounds. From (...) a Utilitarian perspective the emphasis must be on minimizing potential harms. From a Kantian perspective the emphasis must be on giving users complete information so that they can make informed decisions as to whether they are willing to be monitored. Considering the Internet advertising industrys current actions, computer users and government regulators would be well advised, both practically and ethically, to move to a user control model in electronic monitoring.

In May of 2009, the Stockholm Convention added nine chemicals to its list of banned or restricted chemicals. While some businesses may be tempted to see further limitations on chemical production of persistent organic pollutants as an inconvenient hindrance, I argue that business ought to see strengthened rules as an opportunity to improve efficiency and to become more competitive in the global market place both financially and ethically.

This article is devoted to examine two theories on the origin of cognition. The first of them is a neurobiological theory by de authors V. Mountcastle and J. Hawkins working separately. The second one is a theory from the Cognitive Psychology by D. Gentner. It is interesting to check that exists a strong congruence between both of them despite they have absolutely different methodologies. Two different ways lead to postulate the analogy and their mechanisms as the main element of cognition. (...) The present article gives reasons for embracing the analogy as being the main cause of the origin of knowledge in the infant. Besides, it explains why language is the main cause of adult human intelligence and it also denies the need of existence of any innate lexicon or vocabulary. (shrink)
