Switzerland radically changed its migration policy in the mid-nineties from a non-qualified only policy to one that favors the immigration of highly qualified migrants. To analyze the impact of this change on the schooling outcomes of migrants, this paper compares the PISA (OECD Programme for...

We study how childbirth increases the likelihood of young, working mothers to claim disability insurance and how paternity leave could ease this effect. Our event study analysis uses Belgian data to show that the incidence rate of disability across gender only diverges after first-time...

We present a theorem helpful in estimating the mean and variance of a linear function with arbitrary multivariate randomness in its coefficients and variables. We derive a generalized decomposition result from two random linear functions in which the result can be applied to most models using...
