This paper reviews the exciting and rapidly expanding literature on realized volatility. After presenting a general univariate framework for estimating realized volatilities, a simple discrete time model is presented in order to motivate the main results. A continuous time specification provides...

In this paper we study the impact of the international migration of unskilled workers on skill formation and the average skill level in the home country. We analyze what appears to be the least threatening scenario from the point of view of its effect on the supply of skills at home: namely,...
