We study firm heterogeneity in economic development in an overlapping-generations general equilibrium model in which manufacturing firms engage in oligopolistic competition. Individuals differ in their productivities in the manufacturing sector and choose to become entrepreneurs or workers. The...

In this general equilibrium model, banks and manufacturing firms engage in oligopolistic competition. A more advanced manufacturing technology has a higher fixed cost but a lower marginal cost of production. We show that manufacturing firms located in a country with a more efficient financial...

While financial or trade integration between countries may increase the size of the market and helps the adoption of more advanced technologies, will it also increase the level of urban unemployment for a developing country? In this model, there is unemployment in the urban sector. Manufacturing...

In this general equilibrium model, firms engage in oligopolistic competition and choose increasing returns technologies to maximize profits. Capital and labor are the two factors of production. The existence of efficiency wages leads to unemployment. The model can explain some interesting...

The impact of financial integration and product market integration is studied in a general equilibrium model with increasing returns in both the manufacturing sector and the financial sector. Firms engage in oligopolistic competition. An increase of the degree of competition in the financial...

Impact of the ability and the degree of openness of a manager on decision making is studied. Whether a more able manager increases or decreases the effort of a subordinate depends on the relative quality of information. Greater openness is a two-edged sword: it increases the likelihood that more...

The presence of circular causality in a region through factor returns is studied in a general equilibrium model in which firms producing final products engage in oligopolistic competition. The intermediate input is produced by capital and labor with a constant returns to scale technology. If the...

In a planned economy, state monopoly ensures that economies of scale are exploited. However, state monopoly could not commit to reward its workers. Anticipating this, individuals will exert less effort. In a market economy, competition among firms ensures that higher effort from workers will be...

Empirical evidence shows that firms located in regions with larger population size are on average larger and more productive. To explain this empirical observation, firms producing intermediate goods are assumed to choose their technologies with different levels of fixed and marginal costs. In...

This paper studies a general equilibrium model of economic geography in which firms engage in oligopolistic competition. This framework is conducive to analytic results. With increasing returns, oligopolistic competition leads to inter-industry trade between regions rather than intra-industry...
