This paper shows that instrumental variables estimators currently in use, require strong but neglected auxiliary assumptions to be consistent in situations with partially missing instruments. We introduce an alternative instrumental variables estimator that does not require auxiliary assumptions.

Many empirical studies specify outcomes as a linear function of endogenous regressors when conducting instrumental variable (IV) estimation. We show that tests for treatment effects, selection bias, and treatment effect heterogeneity are biased if the true relationship is non-linear. These...

We study the effect of a reduction in employment protection on fertility decisions. Using data from the Italian Labor Force Survey for the years 2013-2018, we analyze how the propensity to have a child has been affected by the 2015 Labor Market Reform, the so-called "Jobs Act", which has...

We study the effect of a reduction in employment protection on workers’ fertility decisions. Using data from the Italian Labor Force Survey for 2013-2018, we analyze how the propensity to have a child has been affected by the 2015 labor market reform dubbed the “Jobs Act,” which reduced...

We investigate how academic promotions affect the propensity of women to have a child. We use administrative data on the universe of female assistant professors employed in Italian universities from 2001 to 2018. We estimate a model with individual fixed effects and find that promotion to...

Using Greek Census data for 1991 and 2001 and applying IV-estimation techniques suggested by Angrist and Evans (1998), we investigate whether parental preferences regarding the sex composition of children identify the causal effect of fertility on maternal employment. The results show that...
