This paper assesses energy efficiency in Swedish industry. Using unique firm-level panel data covering the years 2001-2008, the efficiency estimates are obtained for firms in 14 industrial sectors by using data envelopment analysis (DEA). The analysis accounts for multi-output technologies where...

The production of desirable (good) outputs is frequently accompanied by unintended production of undesirable (bad) outputs. If two or more of these undesirable outputs are produced as byproducts, one may ask: ‘Which bad is worst?’ By worst we mean which bad inhibits the production of...

This paper studies the interaction between economic and environmental performance. Applying the directional output distance function approach, the purpose is to compare estimates of Luenberger total factor productivity indicators, including and excluding bad outputs. Specifically, based on...

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 emissions, and we take a closer look at the pulp and paper sector. Dividing the...

How to significantly decrease carbon dioxide emissions has become one of the largest challenges faced by modern society. The standard recipe prescribed by most economists is to put a price on carbon, either through a tax or through emissions trading. Such measures can reduce emissions...
