We introduce a new two-dimensional measure for the heterogeneity of performance within groups of economic units. This measure accounts both, for the relative performance of the single units of groups and their relative size. We demonstrate that the new measure leads to a much more differentiated...

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...

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...

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...

In this paper, we investigate the link between optimal level of leverage and macroeconomic uncertainty. Using the model of firm's value maximization, we show that as macroeconomic uncertainty increases, captured by an increase in the variability of industrial production or inflation, firms...

Spending on productive infrastructure is seen as an important contributor to long term economic growth. Several authors have documented a downward trend in public investment during the last three decades and warned about its possible detrimental effects on the economy. A not well-realized fact...
