Motivated by Manski and Tamer (2002) and especially their partial identification analysis of the regression model where one covariate is only interval-measured, we offer several contributions. Manski and Tamer (2002) propose two estimation approaches in this context, focussing on general...

This paper explores whether investments in information and communication technologies (ICT) and firm?sponsored training programmes are complementary. Three approaches are applied to panel data from German service companies for the time period 1994?98. Results for a system of interrelated factor...

Using panel data for German and Dutch firms from the services sector, this paper analyses the importance of ICT capital deepening and innovation for productivity. We employ a model that takes into account that innovation and ICT use may be complementary. The results show that the contribution of...

This paper examines how capital is determined by German banks. We analyse whether the determinants found in the previous empirical literature hold for the special German banking sector with its three characteristic banking groups of savings banks, cooperative banks and other banks. On the basis...

The aim of this paper is to construct an indicator of potential growth for developed countries using the insights of the theoretical and empirical growth literature. The Pooled Mean Group Estimator of Pesaran, Shin and Smith (1999) that employs a panel data technique is used. This estimator is...

Between 1991 and 1997 West Germany spent on average about 3.6 bn Euro per year on public sector sponsored training programmes for the unemployed. We base our empirical analysis on a new administrative data base that plausibly allows for selectivity correction by microeconometric matching...

This paper analyses whether wages in Germany respond to firm-specific profitability conditions. Particular emphasis lies on the question of whether the extent of rent-sharing varies across different systems of wage determination. Those may be categorised into sector-specific wage agreements,...

We examine the empirical relation between CO2 emissions per capita and GDP per capita during the period 1960-1996, using a panel of 100 countries. Relying on the nonparametric poolability test of Baltagi et al. (1996), we find evidence of structural stability of the relationship. We then specify...

Our study is based on the traditional Becker-Ehrlich deterrence model, but we analyse the model in the face of currently discussed factors of crime like demographic changes, youth-unemployment and income inequality. We use a panel of the German Laender (states) that allows us to exploit...
