The "common effect" model in program evaluation assumes that all treated individuals have the same impact from a program. Our paper contributes to the recent literature that tests and goes beyond the common effect model by investigating impact heterogeneity using data from the experimental...

Starting from Professor Kornai´s assertion about the necessity to focus on the long-termperspectives of the transformation process, we analyze in this paper the Lisbon performanceof the countries of the European Union from such a long-term, structural perspective. Wepresent in a simple form the...

In an evaluation of a job-training program, the influence of the program on the individualearnings capacity is important, because it reflects the program effect on human capital.Estimating these effects is complicated because earnings are observed for employedindividuals only, and employment is...

Based on a sample of 7,378 firms going public in the 1975-2005 period, we document a significant underperformance of IPO firms over the first year after going public, while there is virtually no underperformance thereafter. Moreover, by decomposing the Carhart-alpha we find that IPO...

We present a regression-based generalization of the calendar time portfolio approach which allows for decomposing the risk-adjusted performance of private investors (or firms or mutual funds) into multivariate and continuous subject characteristics. Our technique remedies several well-known...

Based on a new methodological framework we investigate IPO (under-)performance in asample of 7,378 firms going public in the 1975-2005 period. We explicitly vary the time horizonin our analysis and document a significant underperformance of IPO firms over the firstyear after going public, while...

The present paper examines the relationship between fixed-term employment and jobsatisfaction using individual-level data from the German Socio Economic Panel (GSOEP).According to theoretical expectations, fixed-term employment should be associated with arelative low level of job satisfaction,...

The present paper examines the wage effects of continuous training programs usingindividual-level data from the German Socio Economic Panel (GSOEP). In order to accountfor selectivity in training participation we estimate average treatment effects (ATE and ATT)of general and firm-specific...

We consider the possibility of estimating a Dickey-Fuller regression, constraining the autoregressive parameter to be at most one, and imposing prior knowledge of the sign of the drift parameter. ...

This paper tests whether out-of-sample hedonic value predictions can be improved when a large urban housing market is divided into submarkets.
