| Abstract: | This article analyzes the impacts of debt relief on production and pollution. We develop a two-country overlapping generations model with environmental externalities, public debts and perfect mobility of assets. Pollutant emissions arise from production, but agents may invest in pollution mitigation. Could debt relief be an efficient tool to encourage less developed countries to engage in the fight against climate change? We consider a decrease of the debt of the poor country balanced by an increase of the richer country's debt. We show that debt relief makes it possible to engage poor countries in the process of pollution abatement. Capital, environmental quality and welfare can increase in both countries. This result relies on the environmental sensitivity and the discount factor in the poor country relative to the rich one: the greater they are the more beneficial the debt relief is. |

| Abstract: | 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 analysis (DEA) model to estimate the technology for biofuel and other forest products. We consider that forests are managed to use multiple inputs to produce multiple outputs. Outputs include sawtimber, pulpwood, fuelwood, and bioenergy in terms of GROT. Our model also considers environmental concerns over biodiversity and CO2 emissions from burning biomass. We apply the network DEA model to measure the revenue efficiency of forest production of Swedish forests using a panel consisting of 20 counties and covering the years from 2008 to 2014. Our results show that there exist persistent economic inefficiencies of forest production in some counties, reducing the overall efficiency of Sweden’s forest and wood products industry. In addition, we also estimate the potential increase in bioenergy, deadwood and CO2 emissions reduction from combustion of bioenergy and by-products from sawtimber and pulpwood. |
