This article uses panel data estimation techniques to examine technical efficiency of individual dairy farms in northern Germany. To the extent that agricultural production is characterised by heterogeneous production conditions, estimation techniques that do not account for unobserved...

A detailed decomposition of the sources of the Total Factor Productivity (TFP) growth index within an output distance function framework was carried out, looking at the following components: technical change, change in technical efficiency, scale component, and violations of the profit...

In this paper we merge techniques from the efficiency literature with spatial econometric techniques. In particular, we combine calculation of efficiency from the unit speci c effects with the spatial lag model to develop a spatial autoregressive frontier model for panel data. Features of the...
