This paper is about the alleged tension between methodological individualism and evolutionary ideas in the work of Friedrich Hayek. This issue is much debated, but I focus my attention on a quite original incompatibility argument by Geoffrey Hodgson. Hodgson sympathizes with the evolutionary Hayek, arguing that Hayek’s methodological individualism involves an “ontogenetic” approach to social sc...

In an important contribution to the problem of aggregating infinite utility streams, Svensson (1980) shows the existence of a social welfare relation—a reflexive, transitive and complete binary relation over all possible infinite utility streams—that accommodates the axioms of Pareto and intergenerational equity. This possibility result is in sharp contrast with the seminal contribution by Diam...

Single-sex programs have been implemented in a variety of educational settings to help promote greater engagement of women in STEM fields. However, the mechanisms through which single-sex programs increase women’s engagement in STEM fields are unclear. Drawing from research in social and health psychology, we examined two theoretically-guided predictors of women’s sense of belonging in their ST...

This paper investigates the ex post implementation of a social choice set with two agents. A social choice set F is ex post imple-mentable with two agents if F satises the conditions of ex post incentive compatibility (EPIC) and ex post monotonicity (EM) in an environment that is economic and has a bad outcome. Furthermore, if F is a social choice function, (EPIC), (EM), and an economic environ...

We introduce intention-based social preferences into a mechanism design framework with independent private values and quasilinear payoffs. For the case where the designer has no information about the intensity of social preferences, we provide conditions under which mechanisms which have been designed under the assumption that agents are selfish can still be implemented. For the case where prec...
