A nonparametric Data Envelopment Analysis (DEA) is performed on hospitals in the federal state of Saxony (Germany) and in Switzerland. This study is of interest from three points of view. First, contrary to most existing work, patient days are not treated as an output but as an input. Second,...

Dieser Aufsatz dient dem Versuch, ein konsistentes wirtschaftspolitisches Bewertungsverfahren zur Analyse der Leistungsfähigkeit der genossenschaftlichen Bankunternehmung zu entwickeln. Dafür wird das auf linearer Programmierung beruhende Schätzverfahren "Data Envelopment Analysis (DEA)"...

Performance measurement is an area of crucial interest in asset valuation and investment management. High volatility as well as time aggregation of returns, amongst other characteristics, may distort the results of conventional measures of performance. In this work, we study the performance of...

Using quantile regression and a rich cross section data set for German manufacturing plants this paper documents that the impact of plant characteristics on export activities varies along the conditional size distribution of the export/sales ratio.

This paper starts from the stylized fact that firm size and exporting tends to be positively related. Using large sets of establishment panel data for three different industries from official statistics evidence is presented that the familiar picture of an export/sales ratio that ceteris paribus...

The impact of uncertainty on firms' investment outlays is subject to an ongoing debate. Theory identifies several channels. Irreversibility, financing constraints and risk aversion make a negative relationship between uncertainty and investment likely. On the other hand, the ability of firms to...

This paper tests some of the predictions of recent advances in trade theory that have focused on different trade patterns of firms within the same sector. Helpman, Melitz and Yeaple (2005) develop a model in which innate productivity differences between firms determine the degree of...

18 studies using data from 20 highly developed, developing, and less developed countries document that average wages in exporting firms are higher than in non-exporting firms from the same industry and region. The existence of these so-called exporter wage premia is one of the stylized facts...

This paper analyses the relationship between firm productivity and export behavior in German manufacturing firms. We examine whether productivity increases the probability of exporting, and assert that there is a causal relationship from high productivity to entering foreign markets, as...
