Several approaches for subset recovery and improved forecasting accuracy have been proposed and studied. One way is to apply a regularization strategy and solve the model selection task as a continuous optimization problem. One of the most popular approaches in this research field is given by...

Standard measures of consumer price inflation are based on a bundle of representative goods. It is well known that this approach might overstate inflation for new products and products with fast increasing quality. For this reason, hedonic adjustment methods have been proposed and introduced in...

This paper is concerned with the question as to what extent population size and density affect the cost of providing public services at the subnational level. Empirical estimates of cost functions are obtained from an analysis of the expenditures of German states disaggregated into about 40...

Using a firm-level dataset this paper investigates the impact of taxation on the decision of German multinationals to hold direct investments in other European countries or abroad. Controlling for firm-specific differences in the valuation of potential locations, the results confirm significant...

We argue that in labor markets with central wage bargaining wage flexibility varies systematically across the wage distribution: local wage flexibility is more relevant for the upper part of the wage distribution, and flexibility of wages negotiated under central wage bargaining affects the...

The macroeconomic development in West Germany in the aftermath of unification was characterized by a boom period in 1990/1991, a deep recession in 1992/1993 and a slow recovery since then. In East Germany, in contrast, unification induced a breakdown of production and employment followed by a...

Unification fundamentally changed the terms of quantitative macroeconomic analysis for Germany. Two main areas concerned are data availability for the eastern part of Germany and structural changes within the behavioural equations after unification. Our paper presents results from the estimation...

German unifikation hit the West German economy in a prosperous and appeared as a huge demand shock at least for the first few quarters. This combination resulted in a major increase of imports from the main trading partners of West Germany, which may have helped to cushion recessionary trends...

In the context of EMU fiscal equalization schemes have been proposed as a means to stabilize regions against asymmetric shocks. A theoretical analysis shows that besides reducing the cross-sectional income variance the redistributive element of fiscal equalization causes incentive effects for...

The paper examines the role of the vertical structure of the public sector for economic growth in Germany in a long?term perspective. A theoretical model shows that, due to spillover effects of public service provision across lower level governments, federal government activities could have...
