In this paper, we study environmental efficiency (EE) within a pollution-generating technology. Good output and bad output (pollution) are explicitly modeled by imposing technology properties of disposability and null-jointness. With data on firms from Swedish manufacturing, we investigate the...

Biofuels are increasingly regarded as energy sources with the potential to solve diverse problems related to serious concerns, including climate change, environmental degradation, energy supply, and energy security. Here we examine biofuels, primarily biofuels used for transportation (e.g.,...

Using a growth model that accounts for environmental and climate externalities, we take a closer look at the welfare effects of promoting biomass growth and the use of bioenergy, and especially the role of carbon neutrality. As an illustration, a hypothetical intensive forest cultivation project...

We analyze carbon intensity performance at firm level and the effectiveness of the Swedish CO2 tax. Carbon intensity performance is derived from a production technology and measured as changes in the CO2 emission-output production ratio. As one of the first countries to introduce a CO2 tax in...
