Germany's water supply industry is characterized by a multitude of utilities and widely diverging prices, possibly resulting from structural differences beyond the control of firms' management, but also from inefficiencies. In this article we use Data Envelopment Analysis and Stochastic Frontier...

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...

The traditional approach to measuring allocative efficiency is based on input prices, which are rarely known at the firm level. This paper proposes a new approach to measure allocative efficiency which is based on the output-oriented distance to the frontier in a profit - technical efficiency...
