Experimental data on social preferences present a number of features that need to be incorporated in econometric modelling. We explore a variety of econometric modelling approaches to the analysis of such data. The approaches under consideration are: the Random Utility approach ; the Random Behavioural approach ; and the Random Preference approach. These approaches are applied in various ways to an experiment on fairness conducted by Cappelen et al. :818–827, 2007). Various models that we estimate succeed in capturing the key (...) features of the dataset. Conclusions concerning fairness-related behaviour depend crucially on the choice of econometric model.

Abstract.The starting point of deontic logic is the distinction between non‐normative necessity and normative necessity. The first part of the paper shows that the distinction between normative necessity and non‐normative necessity occurs already in Aristotle's Orgunon. The second part of the paper makes a further distinction within normative deon itself: The distinction between deontic deon and anankastic deon. Anankastic deon behaves differently from deontic deon in a very important respect: Deontic indifference has no anankastic counterpart.

Panel data from the German SOEP is used to test for risk vulnerability in the wider population. Two different survey responses are analysed: the response to the question about willingness-to-take risk in general and the chosen investment in a hypothetical lottery. A convenient indicator of background risk is the VDAX index, an established measure of volatility in the German stock market. This is used as an explanatory variable in conjunction with HDAX, the stock market index, which proxies wealth. The impacts (...) of these measures on risk attitude are identifiable by exploiting the time dimension of the panel and matching survey months with corresponding observations from these time-varying factors. Both of the survey responses allow us to test for decreasing absolute risk aversion ; in one case, we find strong evidence of DARA, while in the other, we do not. Both survey responses also allow us to test for RV, and in both cases we find strong evidence. In the case of the hypothetical lottery response, we are also able to estimate a “coefficient of risk vulnerability”. This is defined as the absolute amount by which absolute risk aversion rises in response to a doubling of background risk. We estimate CRV to be between 1.03 and 1.27. (shrink)

This essay deals with the concept of negation in Deontics. In relation with this concept, the polish logician Jerzy Sztykgold seems to put forward these two thesis: a) a norm may have a negation; b) a norm may be a negation. Sztykgold studies the concept of Inegation of a norm through the analysis of other two concepts of a right or of a duty and the concept of opposition of behaviour), and, as early as 1936, he puts hirnself in a (...) clear position in relation to the problem of the possibility of a logic of norms: There is a deontic analogonof truth, which is the słuszność consequently, for the norms, entities of which the słuszność is predicated, are valid the thesis of the propositional logic that are valid for the apophantic sentences.

Spousal correlation in risk attitude is estimated using data from the German Socio-Economic Panel over the period 2004–2009. We apply the bivariate panel ordered probit model to the analysis of the simultaneous determination of the male’s and the female’s risk attitude, using the survey question about general willingness to take risk, provided on a 0–10 Likert-scale. The correlations between both the individual-specific effects of the two partners and the two within-individual errors are separately estimated, and found to be +0.285 and (...) +0.310, respectively. We consider the former to be a key parameter, since its positive sign may be interpreted in terms of positive assortative mating on risk attitude: individuals tend to form partnerships with others having a similar risk attitude. We also find evidence that this correlation increases with years of marriage, suggesting either a form of spousal socialization or a selection process in which marriage breakdown is more likely in poorly matched couples.

The author returns to a much debated topic, the so-called “Episode of Helen”, which has come to us only through indirect transmission, and endeavors to dismantle the prejudice against Virgilian authorship. G. P. Goold’s pugnacious intervention, dating back to more than half a century ago, contributed decisively – in fact, more than it should have – to the thesis that the text is spurious. A critical analysis of the text will demonstrate this claim to be groundless while offering arguments that (...) support the authenticity of the episode. (shrink)

The necessity to model the mental ingredients of norm compliance is a controversial issue within the study of norms. So far, the simulation-based study of norm emergence has shown a prevailing tendency to model norm conformity as a thoughtless behavior, emerging from social learning and imitation rather than from specific, norm-related mental representations. In this paper, the opposite stance—namely, a view of norms as hybrid, two-faceted phenomena, including a behavioral/social and an internal/mental side—is taken. Such a view is aimed at (...) accounting for the difference between norms, on one hand, and either behavioral regularities (conventions) on the other. This paper, in particular, is addressed to find out the internal ingredients required for the former distinction, i.e., to model norms as distinct from mere conventions, and defined as behaviors spreading to the extent that and because the corresponding commands and beliefs do spread as well. After a brief presentation of a normative agent architecture, the results of agent-based simulations testing the impact of norm recognition and the role of normative beliefs in the emergence and innovation of social norms are presented and discussed. More specifically, the present work will endeavour to show that a sudden external constraint (e.g. a barrier preventing agents from moving among social settings) facilitates norm innovation: under such a condition, agents provided with a module for telling what a norm is can generate new (social) norms by forming new normative beliefs, irrespective of the most frequent actions.

Inextricably bound up with the philosophy of John Searle is, famously among philosophers, the concept of constitutive rules. Less well known, however, is that starting in the 1970s, a conversation on this topic emerged in Italian legal philosophy, reaching a depth and complexity hardly matched anywhere else in the world. This is due chiefly to the work of Gaetano Carcaterra and Amedeo G. Conte. This chapter moves that conversation forward by connecting these different research lines: It shows how the (...) evolution of Searle’s concept of a constitutive rule can ground a critique of Conte’s own concept of a constitutive rule, and how, conversely, those developments in Searle’s ideas are consistent with some sound critiques Conte aimed at Searle’s original thinking on constitutive rules.

Under the assumption that all "rules" are recursive (ECT) the statement $\operatorname{Cont}(N^N,N)$ that all functions from N N to N are continuous becomes equivalent to a statement KLS in the language of arithmetic about "effective operations". Our main result is that KLS is underivable in intuitionistic Zermelo-Fraenkel set theory + ECT. Similar results apply for functions from R to R and from 2 N to N. Such results were known for weaker theories, e.g. HA and HAS. We extend not only (...) the theorem but the method, fp-realizability, to intuitionistic ZF. (shrink)

It is commonly assumed that personalization technologies used by Google for the purpose of tailoring search results for individual users create filter bubbles, which reinforce users’ political views. Surprisingly, empirical evidence for a personalization-induced filter bubble has not been forthcoming. Here, we investigate whether filter bubbles may result instead from a searcher’s choice of search queries. In the first experiment, participants rated the left-right leaning of 48 queries (search strings), 6 for each of 8 topics (abortion, benefits, climate change, sex (...) equality, immigration, nuclear family, Islam, and taxation). An independent sample of participants were then asked to select one of these queries for each of the 8 topics. With the exception of the topic of Islam, participants were significantly more likely to select a query corresponding to their own political leaning, compared to other queries, explaining between 12% and 39% of the variance. A second experiment investigated the effect of the political leaning of the same queries on the overall political leaning of Search Engine Result Pages (SERPs) in Google Search. The top six results of each SERP were rated collectively by a third group of participants, explaining 36.3% of the variance across all 48 search terms (p < .00001). That is, (1) participants in our experiments tended to select own-side search queries, and (2) using those queries tended to yield own-side search results when using the Google search engine. Our results are consistent with the notion of a self-imposed filter bubble in which query selection plays a salient role. (shrink)

This study draws on neo-institutional theory to examine how and why corporate environmental management practices might affect environmental performance. It contributes to the literature by using a large, global data set to investigate the impact of 10 corporate environmental management practices on greenhouse gas emissions or emissions intensity. It focuses on greenhouse gas emissions which pose an existential threat to the people and planet, and the environmental management practices of corporations whose effectiveness has provoked cynicism and claims of “greenwash”. Our (...) results are based on a dynamic, robust and large-scale econometric analysis, which includes tests of association and Granger causation in comparison with earlier research. A key finding, which is of interest not only to the academic literature but also to policymakers and managers, is that environmental performance impacts environmental management practices but not vice versa, supporting the hypothesis that corporations adopt these practices as a symbolic legitimizing device rather than a genuine attempt derived from moral obligation to reduce their greenhouse gases or carbon intensity.

Question and quotation marks tend to proliferate in articles which ask whether Homer can provide any historical information about early Greek society. In this article ‘Homeric’ society will refer to the society which is portrayed in the Iliad and the Odyssey. ‘The World of Odysseus’ will refer to the recension of ‘Homeric’ society which appears in M. I. Finley's book of that name. Finley claims that ‘The World of Odysseus’ is a faithful account of ‘Homeric’ society and that the latter (...) is a literary portrait of a real society that existed in Greece some time during the dark ages. As a result of Finley's influential book, ‘The World of Odysseus’, or something very like it, has found its way into most of the history books generally available in the classroom. In this article I wish to reconsider ‘Homeric’ society and to question the propriety of identifying it with either ‘The World of Odysseus’ or any real society. (shrink)
