Herd Behaviour in Occupational Choice

In this paper we examine why many professional labor markets are disturbed by cycles in the supply of new workers. We present a model where cycles in labor supply are the consequence of herd behavior in occupational choice. We also present evidence from nearly 150 West German labor markets which supports the herd behavior model of labor supply cycles.analysis of education, occupational choice, professional labor markets

Efficient Estimation in Semiparametric GARCH Models

It is well-known that financial data sets exhibit conditional heteroskedasticity.GARCH type models are often used to model this phenomenon. Since the distribution of the rescaled innovations is generally far from a normal distribution, a semiparametric approach is advisable.Several publications observed that adaptive estimation of the Euclidean parameters is not possible in the usual parametrization when the distribution of the rescaled innovations is the unknown nuisance parameter.However, there exists a reparametrization such that the efficient score functions in the parametric model of the autoregression parameters are orthogonal to the tangent space generated by the nuisance parameter, thus suggesting that adaptive estimation of the autoregression parameters is possible.Indeed, we construct adaptive and hence efficient estimators in a general GARCH in mean type context including integrated GARCH models.Our analysis is based on a general LAN Theorem for time-series models, published elsewhere.In contrast to recent literature about ARCH models we do not need any moment condition.garch models;estimation

Cyclical Occupational Choice in a Model with Rational Wage Expectations and Perfect Occupational Mobility

In many professional labor markets the number of new workers follows a cyclical time path. This phenomenon is usually explained by means of a cobweb model that is based on the assumptions of myopic wage expectations and occupational immobility. Since both assumptions are questioned by the empirical literature, we develop an alternative model that is based on the assumptions of rational wage expectations and perfect occupational mobility. Depending on the production function, the model can generate cycles in the number of workers who enter a professional labor market.Occupational choice, Rational expectations, Occupational mobility, Linear dynamics
