- In 2012 the Swedish Environmental Protection Agency was provided with 100,000 ha of productive forest land. The Agency swapped the land to obtain conservation-worthy forests, and these were turned into natural reserves. Conservation without reference to both benefits and cost typically results in inefficient solutions. In this paper we discuss how to select the forest stands to preserve in a cost-effective manner. We also discuss how to design a cost-benefit analysis of the swapping program. We provide several new results regarding the economics of preservation, when land swaps is a viable instrument.

- While support schemes to renewable energy are ubiquitous around the world today, there are few systematic welfare evaluations of their social benefits and costs in an economy-wide setting. We develop a general equilibrium cost–benefit rule to assess changes in quantity based subsidy schemes, “green” certificates, that support renewable electricity generation. An advantage to large-scale numerical models of the same issue is that we can go “into the black box” and uncover key economic mechanisms. We study a second-best economy with distorting taxes and pollution, so that a perturbation of the certificate scheme causes both benefits and costs; these items can be uncovered and estimated using our framework. To this end, we provide a user-friendly approximation for empirical implementation, which means that data requirement is modest relative to a typical computable general equilibrium model. We apply the theory to a currently existing scheme in Sweden taking into account “trickle-down” effects, including e.g. a loss of value-added tax income in the rest of the economy and environmental costs (i.e. externalities from electricity generation not currently internalized). We first present an ex post estimate, i.e. the welfare consequences of having scrapped the existing system 2003–2017 and then an ex ante analysis of extending the system to 2045. The latter includes a systematic sensitivity analysis based on Monte-Carlo simulation. Overall, we find net present value gains from removing the subsidy scheme, taking into account externalities, “trickle-down” and public finance repercussions.

The infinitely worried forest owner key biotopes and forest certification in a Faustmann model
- 2020

Tidskriftsartikel (refereegranskat)abstract
- In this note, we consider a case when a forestry property may lose its market value through "political risk", illustrated here by it being classified as containing a key biotope. If a key biotope is found on a forest property in Sweden, the wood is almost impossible to sell. We show how the Faustmann formula is modified in this case and identify a "balance sheet" effect and a shortened rotation period. The theory seems to have some empirical support, given observed changes in bank lending contracts and alleged changes in forester's behavior to reduce the "political risk".
