We construct a simple model incorporating various urban labour market phenomena obtaining in developing economies. Our initial formulation assumes an integrated labour market and allows for entrepreneurship, self-employment and wage employment. We then introduce labour market segmentation. In...

This paper develops a model in which the interaction of entrepreneurial investments and power of the owners of land or other natural resources determines structural change and economic development. A more equal distribution of natural resources promotes structural change and growth through two...

A society is characterized by the common attitudes and behavior of its members. Such behavior reflects purposive decision making by individuals, given the environment they live in. Thus, as technology changes, so might social norms. There were big changes in social norms during the 20th century,...

This paper investigates the role that idiosyncratic uncertainty plays in shaping social preferences over the degree of labor market flexibility, in a general equilibrium model of dynamic labor demand where the productivity of firms evolves over time as a Geometric Brownian motion. A key result...

This paper provides an introduction and overview of my research on the Economics of Language. The approach is that language skills among immigrants and native-born linguistic minorities are a form of human capital. There are costs and benefits associated with this characteristic embodied in the...

We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...

The traditional model of taste discrimination in labor markets presumes perfect substitution, making it unsuitable for the measurement of discrimination across job assignments. We extend the model to explain cross-assignment discrimination and test it on data from Major League Baseball. A...

We model individual careers in sports and games from initial entry to eventual exit or success as a discrete-choice, finite-horizon optimization problem. We apply this model to the international game of chess and study cross-country differences in the relative success of players. While we find...
