- The main objective of this paper is to analyze the potential goal conflict between two of Sweden's environmental objectives: Sustainable Forests and Reduced Climate Impact – or, more precisely, the conflict between forest conservation and the supply of wood fuel. To accomplish this, we use a forest sector model that includes the suppliers and major users of roundwood. The econometric results, based on a data set that spans 40 years, show that all the own price elasticities have the expected signs. Among the three forestry products, the supply and (long-term) demand of forest fuel seems to be most sensitive to a price change. In a second step, the estimated model is used to simulate the effect of increased forest conservation – the Sustainable Forest objective – on the supply of wood fuel. If oil is used as a substitute, Swedish emissions of greenhouse gases will increase by almost 0.92 percent, which indicates a clear conflict with the Reduced Climate Impact objective.

- The aim of this paper is to explore some of the theoretical and empirical aspects of an economy which includes cultural capital. We use a simple dynamic growth model and the concept of a social accounting matrix (SAM) to illustrate how the addition of income flows and net changes of various natural and cultural resources can be incorporated into a broader measure of welfare. The Swedish reindeer industry, managed by the indigenous Sami people, is used as an example since it is generally regarded to have significant cultural heritage value, beyond its contribution to conventional national accounts. We discuss a theoretically correct compensation to a cultural sector for preserving and maintaining a cultural heritage. Furthermore, we attempt to estimate the cultural value of the Sámi Reindeer sector in Sweden using a CVM survey. The results suggest that the willingness to pay (per year) to maintain cultural heritage at least at the current level may be quite substantive, estimates showing it can be several times the industry's turnover per year.

Acidification Remediation Alternatives : Exploring the Temporal Dimension with Cost Benefit Analysis
- 2010

Tidskriftsartikel (refereegranskat)abstract
- Acidification of soils and surface waters caused by acid deposition is still a major problem in southern Scandinavia, despite clear signs of recovery. Besides emission control, liming of lakes, streams, and wetlands is currently used to ameliorate acidification in Sweden. An alternative strategy is forest soil liming to restore the acidified upland soils from which much acidified runoff originates. This cost-benefit analysis compared these liming strategies with a special emphasis on the time perspective for expected benefits. Benefits transfer was used to estimate use values for sport ffishing and nonuse values in terms of existence values. The results show that large-scale forest soil liming is not socioeconomically profitable, while lake liming is, if it is done efficiently-in other words, if only acidified surface waters are treated. The beguiling logic of "solving'' an environmental problem at its source (soils), rather than continuing to treat the symptoms (surface waters), is thus misleading.

Exploring distributional determinants of large carnivore conservation in Sweden
- 2011

Tidskriftsartikel (refereegranskat)abstract
- This paper aims to fill the gap in the literature about distributional impacts (who wins and who loses) of implementing new management plans for non-market priced environmental goods and services. The focus is on whether and to what extent, age, gender, presence of large carnivores and income affect willingness-to-pay (WTP) for increasing large carnivore stocks in Sweden. Our results contradict findings from previous studies on large carnivores in the sense that patterns change when different distributional dimensions are analysed together. The results indicate that WTP is independent of the presence of large carnivores, except for the group 'young men'. In general, young men are found to be a disparate group.

Cost-effectiveness of silvicultural measures to increase substrate availability for wood-dwelling species : A comparison between boreal tree species
- 2010

Tidskriftsartikel (refereegranskat)abstract
- This study analysed the cost-effectiveness of silvicultural measures that increase substrate availability for saproxylic (wood-dwelling) species. Mixed stands of Norway spruce (Picea abies L.), Scots pine (Pinus sylvestris L.) and birch (Betula pubescens Ehrh and Betula pendula Roth) or aspen (Populus tremula L.) in three regions of Sweden were modelled. Inverted cost-effectiveness was calculated by dividing the economic cost associated with a silvicultural measure by the increase in coarse woody debris (CWD) and an index reflecting substrate availability for red-listed saproxylic beetles and cryptogams, compared with a reference scenario maximizing economic profit. Tree species had a large impact on the cost-effectiveness of green tree retention: Scots pine was the most costly tree species to retain and aspen and birch the most cost-effective. Tree species also had an impact, albeit smaller, on the cost-effectiveness of the creation of high stumps. It was most cost-effective to create high stumps from birch and aspen in southern Sweden, whereas in northern Sweden it was more cost-effective to create high stumps from pine and spruce. Therefore, when increasing the amount of coarse woody debris (CWD), deciduous trees should be targeted in southern Sweden more than in the north. However, it is important that CWD is created from all tree species, because different tree species support different assemblages of saproxylic species. As regards measures that are not associated with particular tree species, retention of snags at final harvest is a cost-effective measure in all regions, whereas increasing the rotation period is costly.

Environmental policy and profitability : Evidence from Swedish industry

Tidskriftsartikel (refereegranskat)abstract
- This study investigates the effect of a CO2 tax on profitability by using firm-level data on output and inputs from Swedish industry between 1990 and 2004. The purpose of this exercise is to investigate the validity of the so-called Porter hypothesis. By utilizing a factor-demand modeling approach, and specifying a profit function that has a technology component dependent upon firm-specific effective tax on CO2, we are able to separate out the effect of regulatory pressure on technological progress. The results indicate that there is evidence of a “reversed” Porter effect in most industrial sectors, especially in energy-intensive industries; that is, after controlling for the fuel price effect, technological progress and consequently profits are further negatively affected by the CO2 tax.

- An introduction of a kilometer tax for heavy goods vehicles can be constrained by the risk of that higher production costs than competitors in other countries will negatively affect regions and industries of policy concern. We estimate factor demand elasticities in the Swedish manufacturing industry using firm level data for the 1990 to 2001 period on input prices and quantities. The results show that the introduction of a kilometer tax for heavy goods vehicles decreases transport demand and increases labour demand. The effects are less pronounced in terms of changes in output, though some industries (e.g. wood, pulp and paper) can be expected to be affected more than others due to their dependence on road freight transport. The regional dimension regarding the consequences of a kilometer tax seems to be small or even nonexisting.

Comparing conventional and new policy approaches for carnivore conservation : Theoretical results and application to tiger conservation

- New policy approaches to facilitate the co-existence of wildlife and livestock are needed for situations where predation incidents greatly impact households’ income and retaliatory killing threatens endangered carnivore species’ survival. In this paper, models are developed to assess how two alternative policy approaches impact a herder’s decisions on carnivore hunting and livestock protection. We find that while the well-established ex-post compensation policy induces suboptimal livestock protection it can generate sufficient incentives for the herder to refrain from hunting so that the carnivore population reaches its socially optimal level. Performance payments are proposed as alternative policy. They are found not to distort livestock protection incentives and can also help achieve a socially optimal carnivore population level. Which of the two scheme types gives rise to less cost is ambiguous. An empirical analysis of the model with data from tiger-livestock conflicts in India is presented.

- Several strains from the genus Trichoderma (Ascomycetes, Hypocreales) are commercially used as biocontrol agents, e.g. in formulations containing the two Trichoderma strains IMI206039 (Hypocrea parapilulifera B.S. Lu, Druzhinina & Samuels) and IMI206040 (T. atroviride P. Karst). To quantify the presence of the two isolates after application, we developed primers for SCAR markers (Sequence-Characterised Amplified Region). In order to quantify both fungal strains simultaneously, we also designed fluorophore-labelled probes distinguishing the two strains, to be used in combination with the SCAR primers. In incubations of two different soils, artificially inoculated and maintained under controlled conditions, the quantification through amplification with the SCAR markers in qPCR and through colony-forming units from plate counting correlated well. Further tests of the markers on samples taken from a golf green treated with a product containing both strains indicated that the two biocontrol strains did not establish, either on the golf green or in the surrounding area.

Tidskriftsartikel (refereegranskat)abstract
- There is a considerable amount of literature dealing with inference about the parameters in a heteroscedastic one-way random-effects ANOVA model. In this paper, we primarily address the problem of improved quadratic estimation of the random-effect variance component. It turns out that such estimators with a smaller mean squared error compared with some standard unbiased quadratic estimators exist under quite general conditions. Improved estimators of the error variance components are also established.
