We study the effects of a conditional cash transfers program on school enrollment and performance in Mexico. We provide a theoretical framework for analyzing the dynamic educational process including the endogeneity and uncertainty of performance at school (passing grades) and the effect of a...

This paper considers the semiparametric identification of endogenous and exogenous peer effects based on group size variation. We show that Lee (2006)’s linear-in-means model is generically identified, even when all members of the group are not observed. While unnecessary in general,...

Self-reported data on sexual behaviors have been criticized to be unreliable. In recent studies, risky sexual behaviors have therefore been measured using biomarkers for curable sexually transmitted infections (STIs). Nevertheless, no previous research have tested how reliable such data are. In...

It is well understood that the two most popular empirical models of location choice - conditional logit and Poisson - return identical coefficient estimates when the regressors are not individual specific. We show that these two models differ starkly in terms of their implied predictions. The...

This paper examines the impact of fiscal incentives on the level of R&D investment. An econometric model of R&D investment is estimated using a new panel of data on tax changes and R&D spending in nine OECD countries over a nineteen-year period (1979-1996). We find evidence that tax incentives...

This Paper analyses the choices of exchange rate regimes in developing countries since 1980. Static and dynamic random-effects multinomial panel models are estimated using simulation-based techniques. Explanatory variables include OCA fundamentals, stabilization considerations, currency crises...

We investigate the determinants of the remarkable increase in intra-regional migrations since the 1980’s in Spain, using a large administrative micro dataset on migrants. Conditional migration probabilities are identified by comparing the migrants’ joint distribution of characteristics to...

While the literature has established that there is substantial and highly selective return migration, the growing importance of repeat migration has been largely ignored. Using Markov chain analysis, this Paper provides a modelling framework for repeated moves of migrants between the host and...

The determinants of the dramatically rising expenditures on health care in general, and on hospital care in particular, have been of prior concern to policy and to research. Using a rich panel data set this paper contributes to this literature by investigating factors determining the demand for...

Several recent studies based on 'exogenous' sources of variation in education outcomes show Instrumental Variables (IV) estimates of returns to schooling that are substantially higher than the corresponding Ordinary Least Squares (OLS) estimates. Card (1995a) suggests that these results can be...
