We introduce a theoretical framework in which to study interdependent preferences, where the outcome of others affects the preferences of the decision maker. The dependence may take place in two conceptually different ways, depending on how the decision maker evaluates what the others have. In...

Health insurance in the United States is typically acquired through an employer-sponsored program. Often an employee offerred employer-provided health insurance has the option to extend coverage to their spouse and dependents. We investigate the implications of the “publicness” of health...

This paper axiomatizes an intertemporal version of the Smooth Ambiguity decision model developed in Klibanoff, Marinacci, and Mukerji (2005). A key feature of the model is that it achieves a separation between ambiguity, identified as a characteristic of the decision maker's subjective beliefs,...

During the postwar period, many countries have de-tracked their secondary schools, based on the view that early tracking was unfair. What are the efficiency costs, if any, of de- tracking schools? To answer this question, we develop a two skills - two jobs model with a frictional labour market,...

In this paper we present a model of implementation based on the idea that agents renegotiate unfeasible allocations. We characterize the maximal set of Social Choice Correspondences that can be implemented in Nash Equilibrium with a class of renegotiation functions that do not reward agents for...

This paper presents an idealized model of social interaction, where preferences are private information and individuals cannot condition their behavior on the identity of whom they are interacting with. An optimal decentralized benchmark rule is identified, where each individual imposes some...

This study is a preliminary exploration on the extent of labor market segmentation (LMS) in Europe and the United States, based on data of earnings mobility prepared for the OECD in the late Nineties. Assessing segmentation is important for a balanced view on the pros-and-cons of labor market...

Inefficiencies in the bureaucratic organization of the state are often viewed as important factors in retarding economic development. Why certain societies choose or end up with such inefficient organizations has received very little attention, however. In this paper, we present a simple theory...
