We analyze the development of employment in start-up cohorts, which is the direct gross employment effect of the new businesses. The data is for West Germany and covers the 1984- 2002 period. While total employment in the cohorts remains above the initial level in manufacturing, we find a...

Using micro-level panel data of about 35,000 firms from the German Cost Structure Census, we analyze the differences of technical efficiency across industries. Technical efficiency is estimated by firms' fixed effects. One striking result is that the distribution of technical efficiency across...

This paper analyzes the distribution of technical efficiency within manufacturing industries. Using a representative sample of 35,000 firms in 255 industries of the German cost structure census, technical efficiencies are estimated by applying a deterministic frontier production function with...

We analyze the effect of industry, region and time on new-business survival rates by means of a multi-dimensional approach. The data relate to West German districts in the 1983-2000 period. The survival chances of start-ups tend to be relatively low in industries characterized by a high minimum...

Using micro-level panel data of about 35,000 firms from the German Cost Structure Census, we analyze the differences of technical efficiency across industries. Technical efficiency is estimated by firms? fixed effects. One striking result is that the distribution of technical efficiency across...

This paper examines the relationship between firm births and job creation in Great Britain. We use a new data set for 60 British regions, covering the whole of Great Britain, between 1980 and 1998. The central theme of the paper is that, with the exception of a recent paper by Audretsch and...
