The role of agricultural productivity in economic development is addressed in a two-sector model of endogenous growth in which a) preferences are non-homothetic and income elasticity of demand for the agricultural good is less than unitary, and b) the engine of growth is learning-by-doing in the...

This paper builds models of nonlinear dynamics in the aggregate investment and borrower net worth and uses them to study the causes and nature of endogenous credit cycles. The basic model has two types of projects: the Good and the Bad. The Bad is highly productive, but, unlike the Good, it...

This paper endogenizes the elderly's labor force participation in an overlapping generations economy under the assumption that retirement is a luxury. In a developed economy, the agents earn a high wage income when young and retire when old. This reduces the labor supply (through a low...

We consider equilibrium selection in 2x2 bimatrix games with two strict Nash equilibria in a random matching framework. The players seek to maximize the discounted payoffs, but are restricted to make a short run commitment. Modeling the friction this way yields equilibrium dynamics of the...

A pairwise random matching game is considered to identify the social environments that give rise to the social custom and fashion cycles. The game, played by Conformists and Nonconformists, can generate a variety of socially stable behavior patterns. In the path-dependence case, Conformists set...

This paper considers a simple pairwise random matching game in the society populated by two groups of agents: Conformists and Nonconformists. Depending on the relative frequencies of intergroup and intragroup matchings, the best response dynamics show three types of asymptotic behaviors: global...

We propose a new approach to model costly international trade, which includes the standard approach, the “iceberg” transport cost, as a special case. The key idea is to make the technologies of supplying the good depend on the destination of the good. To demonstrate our approach, we extend...

One critical aspect of economic development is that productivity growth and a rising standard of living are realized through more roundabout methods of production and increasing specialization of intermediate inputs and producer services. We use an extended version of the Judd-Grossman-Helpman...

In recent years, monopolistic competition models have frequently been applied in macroeconomics, international and interregional economics, and economic growth and development. In this paper, I presenta highly selective review in this area, with special emphasis on the complementarity and its...
