We develop an evolutionary model of growth in which agents choose how to allocate their time between private and social activities. We argue that a shift from social to private activities may foster market-based growth, but also generate social poverty. Within a formal framework that merges a...

We examine how interaction choices depend on the interplay of social and physical distance, and show that agents who are more central in the social network, or are located closer to the geographic center of interaction, choose higher levels of interactions in equilibrium. As a result, the level...

We develop a model where workers both choose their residential location (geographical space) and their social interactions (social space). In equilibrium, we show under which condition some individuals reside close to the job center while others live far away from it. Even though the two...

This chapter focuses on neighborhood effects in housing markets. Households in effect choose neighborhood effects, or more generally social interactions, via their location decisions, which renders them endogenous. Across several classes of models that it examines, it emphasizes how we may...

We develop a model where workers both choose their residential location (geographical space) and social interactions (social space). In equilibrium, we show under which condition the majority group resides close to the job center while the minority group lives far away from it. Even though the...

This paper explores the effects of fiscal competition on local land use. A theoretical analysis considers the tradeoff faced by a local government deciding about the amount of land made available for commercial or residential uses, when its expansion has adverse effects on the quality of life....

We seek to explain the stylized fact that poor households form the majority in the inner city of most American metropolitan areas. Using numerical simulations, we show that (1) typically there exist two equilibria: One in which the poor form the majority in the inner city and the other in which...
