"This paper illustrates the effects of item-nonresponse in surveys on the results of multivariate statistical analysis when estimation of productivity is the task. To multiply impute the missing data a data augmentation algorithm based on a normal/Wishart model is applied. Data of the German IAB...

"In many countries fairly large and persistent regional disparities can be observed for a variety of economic indicators. Since these disparities can not be reduced to one single dimension, a classification system is needed to give a parsimonious overview. The article presents a system which is...

"In the last years the analysis of flow figures turned out to highly informative for labour market research and policy advice. Among researchers it is a well known fact that cross-sectional information about labour market is not sufficient to understand ungoing development. A pure sequence of...

"Recent theoretical research deals with economic costs and benefits of cultural diversity related to immigration. However, empirical evidence regarding the impact of cultural diversity on economic performance is still scarce. This paper investigates the significance of cultural diversity of the...

"Not everyone who plans to set up a firm succeeds in doing so. This paper focuses on the phase before a firm is founded, the pre-nascent stage of the entrepreneurship process. Based upon cross-sectional data from the German section of the Global Entrepreneurship Monitor (GEM), the specific aim...

"This paper analyses the impact of dynamic MAR- and Jacobs-externalities on local employment growth in Germany between 1993 and 2001. In order to facilitate a comparison between the neighbouring countries we firstly replicate the study of Combes (2000) on local employment growth in France and...

"Recently, there has been a renewed interest in the agglomeration wage differential. One of the open research question is whether wage differences between large cities and the rural country are due to unobserved differences in regional price levels. In this paper information on regional price...

"We forecast unemployment for the 176 German labour-market districts on a monthly basis. Because of their small size, strong spatial interdependencies exist between these regional units. To account for these as well as for the heterogeneity in the regional development over time, we apply...

"There is a large body of literature on the determinants of regional variation in new firm formation. In contrast there are few articles on the spatial differences in new firm survival. Using panel data we analyse both items for 74 western German regions over a ten-year period. The positive...

"A casual look at regional unemployment rates reveals that there are vast differences which cannot be explained by different institutional settings. Our paper attempts to trace these differences in the regions' labour market performance back to the regions' specialisation in products that are...
