摘要：This article models the child support and welfare decisions of never-married parents on welfare as a Stackelberg game. The mother chooses whether to exit welfare, report paternity, and to obtain a formal child support order. If a child support order is obtained, the father chooses whether to comply with the order. Simulation results from the structural parameters indicate that increasing the child support disregard increases paternal compliance slightly and affects maternal paternity reporting...

摘要：This article analyses hard and soft budget constraints in a federation, where there is a moral hazard problem between the central and the regional governments. Regional governments can avoid a bailout from the center by exerting costly effort. In this setting, a hard budget constraint is not always optimal because it can provide excessive incentives for high effort, and thus discourage investment that is socially efficient. Thus, a hard budget constraint can imply the opposite kind of ineffici...

摘要：The U.S. economic development in the 19th century was characterized by the westward movement of population and the accumulation of productive land in the West. This article presents a model of migration and land improvement to identify the quantitatively important forces driving these phenomena. The conclusion is that the decrease in transportation costs induced the westward migration, whereas population growth was responsible for the investment in productive land.

摘要：This article's point of departure is that low-quality institutions, concentration of political power and material wealth, and underdevelopment are persistent over time. Its analytical model views an equal distribution of political power as a commitment device to enhance institutional quality, thereby promoting growth. The politically powerful coalition contemplates relinquishing of its power through democratization, weighing this advantageous consequence against the limit on own appropriative ...

摘要：We document and discuss a dramatic change in the cyclical behavior of aggregate skilled hours since the mid-1980s. Using CPS data for 1979:1-2003:4, we find that the volatility of skilled hours relative to the volatility of GDP has nearly tripled since 1984. In contrast, the cyclical properties of unskilled hours have remained essentially unchanged. We evaluate whether a simple supply/demand model for skilled and unskilled labor with capital-skill complementarity in production can help explain...

摘要：The article studies the effects of inflation on real wage dispersion in a search-monetary framework. The economy is characterized by frictions in both the goods and the labor markets. In the goods market, buyers and sellers bargain over prices, whereas in the labor market firms post wage offers. In equilibrium, a lower inflation rate increases the dispersion of real wages. This result is consistent with both the observed trends in wage dispersion and the inflation rate witnessed in the 1980s a...

摘要：This article tests between the standard random matching function approach and stock-flow matching while controlling for temporal aggregation bias. Consistent with previous empirical work, the random matching function fits the matching data reasonably well. But match flows are more highly correlated with vacancy inflows than is consistent with the random matching approach. Instead the data support stock-flow matching, where unemployed workers match directly with suitable new vacancies as such v...
