We apply the network DEA model to measure the revenue efficiency of forest production of Swedish …Forest fuel defined as branches and tops (GROT) of harvested trees represents a large share of forest biomass and is … persistent economic inefficiencies of forest production in some counties, reducing the overall efficiency of Sweden's forest and …

In this paper we present a new approach to evaluate the environmental efficiency of decision making units. We propose a … environmental efficiency being determined by the efficiency of both stages. Taking the dependencies between the two stages into … account, we show how nonparametric methods can be used to measure environmental efficiency and to decompose it into production …
