We derive bounds for the average of math and language scores of elementary school students in Italy correcting for pervasive score manipulation. Information on the fraction of manipulated data is retrieved from a natural experiment that randomly assigns external monitors to schools. We show how...

We consider a general sample selection model where unit and item nonresponse simultaneously affect a regression relationship of interest, and both types of nonresponse are potentially correlated. We estimate both parametric and semiparametric specifications of the model. The parametric...

Over the last decades spatial econometrics models have represented a common tool for measuring spillover effects across different geographical entities (counties, provinces, regions or nations). Unfortunately, no one has considered that when these entities share common borders but obey to...

This paper investigates the impact of the public smoking ban which came into effect in Italy on January 2005 on individual smoking behaviour. Current empirical evidence supports the existence of a negative effect of the Italian ban on smoking prevalence and consumption in the general population....

The aim of the paper is to relax distributional assumptions on the error terms, often imposed in parametric sample selection models to estimate causal effects, when plausible exclusion restrictions are not available. Within the principal stratification framework, we approximate the true...

Using a regression discontinuity design, we document the effect of publicizing a procurement auction on entry and outcomes. We collect a large sample of procurement auctions, which by Italian law are assigned different publicity levels on the basis of their reserve price. We find that auctions...
