Housing developments (condos and suburban developments) are not necessarily homogeneous. Developers provide different types of units with various sizes and other characteristics catering to different types of customers. In this paper, we allow local consumption externalities within each...

We characterize efficient allocations and cyclical fluctuations in a labor selection model. Potential new hires are heterogenous in the cross-section in their degree of training costs. In a calibrated version of the model that identifies costly selection with micro-level data on training costs,...

This paper discusses uniqueness and efficiency of user equilibrium in transportation networks with heterogeneous commuters. Daganzo (1983, Transportation Science) proved the uniqueness of (stochastic) user equilibrium when commuters have heterogeneous tastes over possible paths but identical...

Using firm level panel data from twelve developing countries we explore if financial liberalization improves the efficiency with which investment funds are allocated. A summary index of the efficiency of investment allocation that measures whether investment funds are going to firms with a...

Scotchmer and Wooders (1987) show that efficient clubs are homogeneous when consumers are divisible in Berglas's (1976) anonymous crowding model. However, if consumers are not divisible or if clubs have multiple facilities with economies of scope, mixed clubs are efficient. In such a model, we...

Has financial liberalization improved the efficiency with which investment funds are allocated to competing uses? In this paper, we address this question, using firm level panel data from twelve developing countries. The basic idea is to investigate whether financial liberalization has increased...

Within the last decade kidney exchange has become a mainstream paradigm to increase the number of kidney transplants. However, compatible pairs do not participate, and the full benefit from exchange can be realized only if they do. In this paper, we propose a new incentive scheme that relies on...

We consider competitive markets for multiple commodities with endogenous formation of one- or two-person households. Within each two-person household, externalities from the partner's commodity consumption and unpriced actions are allowed. Each individual has two types of traits: observable...
