An alternative to estimation ofmicroeconometricmodels under the assumption of normality of the distribution of the disturbances is semi-nonparametric maximum likelihood estimation. In a particular class of this kind of models, the density function of the disturbances is approximated by a Hermite...

In this paper we introduce a test for the normality assumption in the sample selection model. The test is based on a generalization of a semi-nonparametric maximum likelihood method. In this estimation method, the distribution of the error terms is approximated by a Hermite series, with...

This overview describes the development of methods for empirical research in the field of labor economics during the past four decades. This period is characterized by the use of micro data to answer policy relevant research question. Prominent in the literature is the search for exogenous...
