Why Does Asset Inequality Affect Unemployment? A Study of the Demand Composition Problem

(with Jean-Marie Baland), Journal of Development Economics 35, 69-92, 1991.

Summary. This paper is devoted to a general equilibrium analysis of the relationship between the inequality in asset holdings and the aggregate levels of output and employment in a developing economy. Since luxuries and basic goods compete for the use of the same scarce resources, unemployment is conceived as a mechanism whereby the market demand for basic goods can be limited to a sufficiently low level so that the high demand for luxuries can be met. The ambiguous effects of capital accumulation on employment are also examined.

Nonpaternalistic Intergenerational Altruism

Journal of Economic Theory 41, 112-132, 1987.

Summary. The paper develops a concept of equilibrium behaviour  in a model of nonpaternalistic intergenerational altruism. When each generation’s utility depends on that of at least two successors, equilibria may be inefficient.

Labor Tying

(with Anindita Mukherjee), Journal of Development Economics 47, 207-239, 1995.

Summary. The co-existence of seasonal fluctuations in income and imperfect credit markets suggests that tied contracts should dominate rural labor markets. However,  empirical observation from India suggests that this is far from being the case, and indeed, that there is a declining trend in  labor tying. In our model,  casual labor markets are always active despite the presence of  seasonality, and a variety of implications are derived that  link economic growth, changing information flows, and the decline of labor tying over time.
