We construct a dynamic Ricardian model with a nominal exchange rate and trade costs. The model predicts that the nominal wages of the trading countries exhibit stronger positive comovements when the countries fix their bilateral exchange rates, while comovements of real wages are not affected by...

This paper develops a simple, general equilibrium model in which competition policies--both entry and antitrust policies--can change the skill premium for wages. The model shows that under variety-skill complementarity, entry deregulation that reduces the fixed costs of entry increases the skill...

Households have many economic roles in society. One of such roles is to share household-level public goods that are jointly consumed by members of the household. Several theoretical models have been proposed in the literature: the unitary model, the non-cooperative game theoretical model and the...

The effect of accepting more immigrants on welfare in the presence of a pay-as-you-go social security system is analyzed theoretically and quantitatively. First, it is shown that if initially there exist intergenerational government transfers from the young to the old, the government can lead an...

In the standard multi-period model, the consumption tax and the wage tax are equivalent. When a capital market is incomplete, such that the rate of return from capital is idiosyncratic, the consumption tax, in contrast to the wage tax, can play a role in risk-sharing. However, risk-sharing may...

This paper empirically examines whether and how experiencing climate-related disasters can improve the rural poorfs adaptation to climate change through community-based resource management. Original household survey data in Fiji capture the unique sequence of a tropical cyclone and the...

This article examines the substitutability, efficiency, and evolution of an important nonmarket institution in agrarian societies ? labor sharing. From analyses of field-level data on forest clearing through time among shifting cultivators in the Peruvian Amazon, we find: (1) no productivity...

This study proposes an approximation of European option prices under arbitrary diffusion processes of the spot price. The key is to approximate the characteristic function of the log spot price process as the solution to ordinary differential equations. The option price is then obtained by the...

As part of public procurement, many governments adopt small business programs to pro- vide contract opportunities for businesses often with preferences for firms operated by mem- bers of groups designated as disadvantaged. The redistribution arising from such programs, however, can introduce...

A rising skill premium in two countries can be explained by the Heckscher-Ohlin model assuming a "skill intensity reversal." This assumption, however, poses an empirical challenge since past research has found little evidence for the so-called "factor intensity reversal." We now show clear-cut...
