Abstract: In this paper, we use an event-study approach to assess the effect of an extended school time program on college admission test scores. We find large positive effects on Humanities, Language, Math, Sciences, and Writing scores. Furthermore, results suggest that these effects are driven by the increased instruction time component of the program.  


Abstract: Distortions tied to firms’ characteristics are usually associated with some degree of misallocation of resources and loss of aggregate productivity. Although the estimation and identification of production functions have received many contributions recently, there is not a discussion on the performance of those methods under the presence of severe endogenous distortions. We show that under these circumstances a necessary assumption of recent production function estimators is violated and estimation became problematic. Empirically, we show that this identification problem creates systematically biased estimates of firm-level productivity and TFP dispersion. Ignoring these effects may drive misleading policy conclusions.
