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 space - and which does not require information on input prices. To …

This paper aims to examine the relative efficiency of German engineering firms using a sample of roughly 23 …-growth, it is expected that a majority of firms is operating quite efficiently and that the density of efficiency scores is … whether these firms are the most efficient ones. Finally an increasing efficiency gap between size classes over time is …

In this paper, we present a nonparametric comparative efficiency analysis of 179 communal public transport bus … companies in Germany (1990-2004). We apply both deterministic data envelopment analysis (DEA) and bootstrapping to test the … average technical efficiency of German bus companies is relatively low. We observe that the industry appears to be …
