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...

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 propose a theoretical framework to study the determinants of ethnic and religious identity along two distinct motivational processes which have been proposed in the social sciences: cultural conformity and cultural distinction. Under cultural conformity, ethnic identity is reduced by...

Poverty measures in developing countries often ignore the distribution of resources within families and the gains from joint consumption. In this paper, we extend the collective model of household consumption to recover mother's, father's and children's shares together with economies of scale,...

This paper studies the assignment of decision makers to two committees that make decisions by a simple majority rule. There is an even number of decision makers at each of various skill levels and each committee has an odd number of members. Surprisingly, even with the symmetric assumptions in...

We develop a model where formal sector firms pay tax and informal ones do not, but informal firms risk incurring the penalty associated with non-compliance. Workers may enter self-employment or search for jobs as employees. Workers with higher managerial skills will run larger firms while...

We propose a new methodology to estimate the share of household income accruing to children (i.e., the cost of children). Following the principle of the Rothbarth approach, the identification of the children's share requires the observation of at least one adult-specific good. However, our...

The aim of this paper is to investigate whether return migrants are more likely to become entrepreneurs than non-migrants. We develop a theoretical search model that puts forward the trade off faced by returnees since overseas migration provides an opportunity for human and physical capital...

The minimum wage rate has been introduced in many countries as a means of alleviating the poverty of the working poor. This paper shows, however, that an imperfectly enforced minimum wage rate causes small firms to face an upward-sloping labor supply schedule. Since this turns these firms into...
