This paper considers the large sample behavior of the maximum likelihood estimator of random effects models. Consistent estimation and asymptotic normality as N and/or T grows large is established for a comprehensive specification which allows for serial correlation in the form of AR(1) for the...

The paper studies the determinants of labor force participation by East German women after unification. To isolate the role of preferences on labor force participation from individual characteristics, we develop a panel data model that simultaneously explains participation, employment, and...

Shortage of nurses is a problem in several countries. It is an unsettled question whether increasing wages constitute a viable policy for extracting more labor supply from nurses. In this paper we use a unique matched panel data set of Norwegian nurses covering the period 1993-1997 to estimate...

New multivariate panel cointegration methods are used to analyze nominal exchange rates and prices in the four major economic powers in Europe, France, Germany, Italy and Great Britain for the post- Bretton Woods period. We test for PPP and find that the theoretical PPP relationship does not...

This paper studies signs and reasons of decline of job stability in West Germany. Using data from the longitudinal German Socio-Economic Panel 1984-1997 (about to be extended until 1999), we look at two measures for job stability. Based on repeated cross sectional data we first show that medium...

This paper investigates the effects of monetary policy on firms' investment behaviour. The analysis relies on a comprehensive database of Belgian firms covering all sectors of economic activity and firms of all sizes. We proceed in two steps. First, we estimate a reduced-form investment equation...

Using a slightly modified version of the Kaplan-Zingales (1997) model we show that it is likely that firms facing high uncertainty rely more on cash flow. Next we illustrate this result using an investment panel data model of Dutch listed firms. Using a threshold estimator we determine the...

Cumby (1996) suggests that (i) deviations from MacParity are stationary, (ii) relative Big Mac prices converge rapidly and (iii) provide significant information on likely future exchange rate movements. This paper examines to what extent these results can be generalised to other micro-level...

An IV approach, using as instruments nonlinear transformations of the lagged levels, is explored to test for unit roots in panels with general dependency and heterogeneity across cross-sectional units. We allow not only for the cross-sectional dependencies of innovations, but also for the...
