The evidence for other-regarding preferences is extensive. How should an individual with other regarding preferences compare two distinct distributions of income? We show that the classical concepts of first and second order stochastic dominance are inadequate to answer this question. We develop the relevant stochastic dominance concepts for the case of the popular other-regarding preferences in Fehr and Schmidt (1999) that we call FS preferences; we consider the linear and non–linear forms of FS preferences. These new dominance concepts, that we call first and second order FS dominance provide sufficient conditions for ranking income distributions. We showthat our concepts can be extended to uncertainty and are applicable to some other models of other-regarding preferences. Our use of a discrete framework is empirically realistic and avoids measure theoretic issues arising under the continuous case.

We build a political economy model in order to shed light on the empirically observed simultaneous increase in university size and participation gap. Parents differ in income and in the ability of their unique child. They vote over the minimum ability level required to attend public universities, which are tuition-free and financed by proportional income taxation. Parents can invest in private tutoring to help their child pass the admission test. A university participation gap emerges endogenously with richer parents investing more in tutoring. A unique majority voting equilibrium exists, which can be either classical or “ends-against-the-middle” (in which case parents of both low- and high-ability children favor a smaller university). Four factors increase the university size (larger skill premium enjoyed by university graduates, smaller tutoring costs, smaller university cost per student, larger minimum ability of students), but only the former two also increase the participation gap. A more unequal parental income distribution also increases the participation gap, but barely affects the university size.

We show that the widely used Boston Mechanism (BM) fosters ability and socioeconomic segregation across otherwise identical public schools, even when schools do not have priorities over local students. Our model includes an endogenous component of school quality - determined by the peer group - and an exogenous one. If there is an exogenously worse public school, BM generates sorting of types between a priori equally good public schools: an elitist public school emerges. A richer model with some preference for closer schools and flexible residential choice does not eliminate this effect. It rather worsens the peer quality of the nonelitist school. The existence of private schools makes the best public school more elitist, while reducing the peer quality of the worst school. The main alternative assignment mechanism, Deferred Acceptance, is resilient to such sorting effects.

This paper sets out to explain the historical development of the skill premium in western Europe over a period ranging from the pre-modern era to the modern era (circa 1300 to 1914). We develop a model of the skill premium and technological change over the very long run which endogenously accounts for the transition across different growth regimes in this period. The model integrates two key elements in long-run growth, the human capital investment and the capital-human capital ratio, into the analysis and successfully explains the declining skill premium from 1300 to 1600 and the stable skill premium from 1600 to 1914. The explanation elucidates a number of well-known historical facts that have not been previously examined in the study of the skill premium.

We report the results of an experiment we performed to test the matching probabilities for the Ellsberg paradox predicted by the quantum decision model of al-Nowaihi and Dhami (2016). We fi…nd that the theoretical predictions of that model are in conformity with our experimental results. This supports the thesis that violations of classical (Kolmogorov) probability theory may not be due to irrational behaviour but, rather, due to inadequacy of classical probability theory for the description of human behaviour. Unlike earlier quantum models of the Ellsberg paradox, our model makes essential use of quantum probability. It is also more parsimonious than earlier models.
