摘要：This paper addresses microeconometric evaluation by matching methods when the programs under consideration are heterogeneous. Assuming that selection into the different subprograms and the potential outcomes are independent given observable characteristics, estimators based on different propensity scores are compared and applied to the analysis of active labor market policies in the Swiss region of Zurich. Furthermore, the issues of heterogeneous effects and aggregation are addressed. The resu...

摘要：Strategic restructuring of firms through investment is key to a transition from plan to market. Using data on industrial firms in the Czech Republic during 1992-1998, we find that foreign-owned companies invest the most and cooperatives the least, that private firms do not invest more than state-owned ones, and that cooperatives and small firms are credit rationed. Given the large volume of nonperforming bank loans to firms and the high rate of investment of large state-owned and private firms...

摘要：This paper studies how the Hodrick-Prescott filter should be adjusted when changing the frequency of observations. It complements the results of Baxter and King (1999) with an analytical analysis, demonstrating that the filter parameter should be adjusted by multiplying it with the fourth power of the observation frequency ratios. This yields an HP parameter value of 6.25 for annual data given a value of 1600 for quarterly data. The relevance of the suggestion is illustrated empirically.

摘要：This paper analyzes differences in the likelihood that black and white families become homeowners. By following a sample of black and white renters over time, we are able to separately study racial differences in the likelihood of applying for a mortgage and in the likelihood that a mortgage application is accepted. Although its effect on the race gap in housing transitions is small, we find strong evidence that black applicants are almost twice as likely as comparable white households to be r...

摘要：This paper uses data from the Census Bureau's Longitudinal Research Database to describe the dynamics of geographic concentration in U.S. manufacturing industries. Agglomeration results from a combination of the mean reversion and randomness in the growth of state-industry employment. Although industries' agglomeration levels have declined only slightly over the last quarter century, we find a great deal of movement for many geographically concentrated industries. We decompose aggregate concen...

摘要：This paper seeks to reconcile the growth empirics technique of Mankiw. Romer, and Weil (1992) with the empirical results of Barro and Sala-i-Martin (1991) through the development of a new database covering the 1977-96 period. We create state-by-state capital stock and gross investment estimates by apportioning the national capital stock among the states. Using these estimates along with gross state product and employment data, we find evidence that the Solow growth model explains state-wide gr...
