Why in some urban areas do rich and poor households cohabit at the community level while, in others, we observe a sorting by income? To answer this question I develop a two-community general equilibrium framework of school quality, residential choice and tax decision. The model predicts that in...

We present a new version of the overtaking criterion, which we call generalized time-invariant overtaking. The generalized time-invariant overtaking criterion (on the space of infinite utility streams) is defined by extending proliferating sequences of complete and transitive binary relations...

We study equity in economies where agents are endowed with different, non-transferable, personal talents. To compensate them for such differences a given amount of money needs to be shared among them. We axiomatize a family of social orderings over allocations based on efficiency, fairness and...

Probabilistic measures of a priori voting power are useful tools to access actors‚ influence on collective decision-making either for the purpose of designing a voting organ or to model particular policy cases. This paper makes an attempt to reduce a dynamic voting process into a cooperative...

Many acts of sacrifice cannot be accounted for as instances of sophisticated selfishness, altruism, Kantian duty, or collusion of the powerful. Economists find these acts puzzling and seek to accomodate them within standard instrumental models of increasing complexity. The paper argues in favor...

This article addresses the important issue of anchoring in contingent valuation surveys that use the double-bounded elicitation format. Anchoring occurs when responses to the follow-up dichotomous choice valuation question are influenced by the bid presented in the initial dichotomous choice...

In this paper we develop a theoretical model of the mechanisms behind the voluntary provision of public knowledge goods in coalitions in presence of social preferences. The model builds on the large empirical literature on voluntary production of pooled public knowledge goods, such as source...

This paper studies the effect of liberalizing the international mobility of college-educated workers on the world economy. First, we combine data on effective and desired migration to identify the net pool of foreign talents (NPFT) of selected high-income countries. So far, the EU15 has poorly...

This paper quantitatively investigates the short- and long-run effects of liberalizing global migration on the world distribution of income. We develop and parametrize a dynamic model of the world economy with endogenous migration, fertility and education decisions. We identify bilateral...
