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...

The documented historical rise in female labour force participation has flattened in recent decades, but the proportion of mothers working full-time has steadily increased. We provide the first empirical evidence that the increase in mothers' working hours is amplified through the influence of...

The well documented rise in female labour force participation in the last century has flattened in recent decades, but the proportion of mothers working full-time has been steadily increasing. In this paper we provide the first empirical evidence that the increase in mothers' working hours can...
