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 in this study. First, it is shown that if intergenerational government transfers initially exist from the young to the old, the government can...

This paper develops a simple model that provides a unified explanation of the increased skewness of wage income distribution based on differences in flexibility of skills--modeled as differences in the setup costs required to combine/perform a given number of tasks. Our numerical experiments in...

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...

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 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...
