In high-tech industries, one important method of diffusion is through employee mobility: many of the entering firms are started by employees from incumbent firms using some of their former employers' technological know-how. This paper explores the effect of incorporating this mechanism in a...

Economists have suggested that the quality of higher education is not independent of the sources of funds used to fund that education. This paper examines the relationship between student measures of teaching quality and institutional revenue sources. The results indicate that a greater reliance...

On April 1, 1864 the Confederate Currency Reform Act reduced the money supply in the Eastern Confederacy by one third. The delayed implementation of the reform west of the Mississippi provides a counterfactual view of what may have happened in the east had the reform not been enacted. This...

This paper revisits the puzzle of low returns on Swiss Franc assets using a new data set of portfolio holdings of residents and non residents at Swiss banks. The main findings are as follows. First, we find that the return anomaly is present only for fixed income assets and not for equity....

The need for better targeting of active labour market programmes is evident from the many evaluation studies that find insignificant or even negative effects. A statistical system could contribute to a more precise targeting of labour market programmes to those individuals who are likely to...

We formulate an efficiency wage model with on-the-job search where wages depend on turnover and employers may use information on whether the searching worker is employed or unemployed as a hiring criterion. We show theoretically that ranking of job applicants by employment status affects both...

This paper uses factor models to identify and estimate distributions of counterfactuals. We extend LISREL frameworks to a dynamic treatment effect setting, extending matching to account for unobserved conditioning variables. Using these models, we can identify all pairwise and joint treatment...

This paper summarizes our recent research on evaluating the distributional consequences of social programs. This research advances the economic policy evaluation literature beyond estimating assorted mean impacts to estimate distributions of outcomes generated by different policies and determine...

This paper decomposes the participation process of a prototypical program into eligibility, awareness, application, acceptance and enrollment. With this decomposition, we determine the sources of unequal participation for different groups, and demonstrate that variables often have very different...

This paper develops two methods for estimating the effect of schooling on achievement test scores that control for endogeneity of schooling by postulating that both schooling and test scores are generated by a common unobserved latent ability. These methods are applied to data on schooling and...
