Forest fuel defined as branches and tops (GROT) of harvested trees represents a large share of forest biomass and is increasingly viewed as a potential energy source. This study assesses the economic potentials of forest bioenergy production in Swedish forests, using a network data envelopment...

In this paper, we measure the technical efficiency for local electricity distribution firms in Sweden, and in particular how small- and micro-scale generation affects efficiency scores. Using two-stage data envelope analysis to model the technical efficiency and a double bootstrap approach to...

In this paper we study environmental efficiency within a pollution generating technology. Pollutants, or bads, are explicitly modeled by imposing technology properties of disposability and null-jointness. With data on firms from Swedish manufacturing, we investigate the potential to reduce...
