This article examines the efficiency of wind energy production. We quantify production losses in four wind parks across Germany for 19 wind turbines with non-convex efficiency analysis. In a second stage regression, we adapt the linear regression results of Kneip, Simar, Wilson (2014) to explain...

Structural change in agriculture is characterized by the interdependency of farms' growth decisions due to the limited availability of the production factor land. This paper adds to the sparse empirical literature on the relation between land market concentration and farm size changes,...
