- 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.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Paper [I] Energy efficiency improvement (EEI) benefits the climate and matters for energy security. The potential emission and energy savings due to EEI may however not fully materialize due to the rebound effect. In this study, we measure the size of the rebound effect for fuel and electricity within the four most energy intensive sectors in Sweden: Pulp and paper, Basic iron and steel, Chemical, and Mining. We use a detailed firm-level panel data set for 2000–2008 and apply a stochastic frontier analysis (SFA) for measuring the rebound effect. We find that neither fuel nor electricity rebound effects fully offset the potential energy and emission savings. Among the determinants, we find the CO2 intensity and the fuel/electricity shares to be useful indicators for identifying firms with higher or lower rebound effects within each sector.Paper [II] Energy efficiency improvement (EEI) is generally known to be a cost-effective measure for meeting energy, climate and sustainable growth targets. Unfortunately, behavioral responses to such improvements (called energy rebound effects) may reduce the expected savings in emissions and energy from EEI. Hence, the size of this effect should be considered to help set realistic energy and climate targets. Currently there are significant differences in approaches for measuring rebound effect. Here, we used a two-step procedure to measure both short- and long-term energy rebound effects in the Swedish manufacturing industry. In the first step, we used data envelopment analysis (DEA) to obtain energy efficiency scores. In the second step, we estimated energy rebound effects using a dynamic panel regression model. This approach was applied to a firm-level panel dataset covering all 14 sectors in the Swedish manufacturing industry over the period 1997–2008. We showed that, in the short run, partial rebound effects exist within most of manufacturing sectors, meaning that the rebound effect decreased, but did not totally offset, the energy and emission savings expected from EEI. The long-term rebound effect was smaller than the short-term effect, implying that within each sector, energy and emission savings due to EEI are larger in the long run compared to the short run.Paper [III] Energy inefficiency in production implies that the same level of goods and services could be produced using less energy. The potential energy inefficiency of a firm may be linked to long-term structural rigidities in the production process and/or systematic shortcomings in management (persistent inefficiency), or associated with temporary issues like misallocation of resources (transient inefficiency). Eliminating or mitigating different inefficiencies may require different policy measures. Studies measuring industrial energy inefficiency have mostly focused on overall inefficiencies and have paid little attention to distinctions between the types. The aim of this study was to assess whether energy inefficiency is transient and/or persistent in the Swedish manufacturing industry. I used a firm-level panel dataset covering fourteen industrial sectors from 1997–2008 and estimated a stochastic energy demand frontier model. The model included a four-component error term separating persistent and transient inefficiency from unobserved heterogeneity and random noise. I found that both transient and persistent energy inefficiencies exist in most sectors of the Swedish manufacturing industry. Overall, persistent energy inefficiency was larger than transient, but varied considerably in different manufacturing sectors. The results suggest that, generally, energy inefficiencies in the Swedish manufacturing industry were related to structural rigidities connected to technology and/or management practices.Paper [IV] The aim of this paper was to investigate whether the environment and employment compete with each other in Swedish manufacturing industry. The effect of a marginal increase in environmental expenditure and environmental investment costs on sector-level demand for labor (employment) was studied using a detailed firm-level panel dataset for the period 2001–2008. The results showed that the sign and magnitude of the net employment effects ultimately depend on the aggregate sector-level output demand elasticity. If the output demand is inelastic, these costs induce small net improvements in employment, while a more elastic output demand suggests negative, but in most sectors relatively small, net effects on demand for labor. Hence, the results did not generally indicate a substantial trade-off between jobs and the environment. The general policy recommendation that can be drawn from this study is that, in the absence of empirically estimated output demand elasticities, a careful attitude regarding national environmental initiatives for sectors exposed to world market competition should be adopted.

The rebound effect in the Swedish heavy industry
- 2017

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Energy efficiency improvement (EEI) benefits the climate and matters for energy security. The potential emission and energy savings due to EEI may however not fully materialize due to the rebound effect. In this study, we measure the size of rebound effect for the two energy types fuel and electricity within the four most energy intensive sectors in Sweden – pulp and paper, basic iron and steel, chemical, and mining. We use a detailed firm-level panel data set for the period 2000-2008 and apply Stochastic Frontier Analysis (SFA) for measuring the rebound effect. We find that both fuel and electricity rebound effects do not fully offset the potential for energy and emission savings. Furthermore, we find CO2 intensity and fuel and electricity share as the two main determinants of rebound effect in Swedish heavy industry. Our results seems to imply that it matters both to what extent and where to promote EEI, as the rebound effect varies between sectors as well as between firms within sectors.

Accounting for cultural heritage : A theoretical and empirical exploration with focus on Swedish reindeer husbandry
- 2010

Tidskriftsartikel (refereegranskat)abstract
- 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.

Prevention or cure? Optimal abatement mix

Tidskriftsartikel (refereegranskat)abstract
- We develop a model for pollution abatement that distinguishes between prevention and treatment technologies, in order to better understand the optimal mix of abatement measures. Our model separates the production process into two stages, an initial production and prevention stage and a final treatment (or cure) stage. We allow for reallocation of abatement investment across the production stages, in order to improve overall abatement and production and to better understand the tradeoffs between abatement measures. This framework is relevant in practice for numerous industrial production processes, including manufacturing and energy, which employ different abatement measures at different stages of production. In our application to Sweden’s pulp and paper sector, we find the industry could achieve further gains to both production and emissions reductions, beyond those estimated using more common single-stage technology estimation methods, by reallocating abatement investments. These results could be used to improve firm environmental management decisions, and to better target policy incentives to specific forms of abatement.

Bokkapitel (refereegranskat)abstract
- Production theory offers a mathematical framework for modeling important relationships between production activities and the environment. These include the generation and valuation of production-related environmental effects, environmental contributions to production processes, and production effects of environmental management practices. In this chapter, we review the seminal and recent empirical work in each of these areas. We anchor our review to multi-input/multi-output production processes, as these make up a large share of environmental applications in the field, and their associated models offer the practitioner considerable flexibility in terms of specification and estimation.

Valuing Ecosystem Services for Agricultural TFP: A Review of Best Practices, Challenges, and Recommendations
- 2022

Ingår i: Sustainability. - : MDPI. - 2071-1050. ; 14:5
-
Forskningsöversikt (refereegranskat)abstract
- This paper provides a brief overview of methods to incorporate ecosystem service values into measures of agricultural total factor productivity (TFP), both in theory and in practice. This includes a review of the academic literature, a summary of related economic index theory, and a comparison of agency guidelines. We consider areas of consensus between the agencies and the research literature, as well as open debates surrounding the implementation of a standardized ecosystem accounting framework to integrate with existing TFP measures. This helps to bridge the gap between theoretical approaches to measurement and valuation in the research literature and their implementation in practice by national accounting agencies. Better connecting theory to practice also serves to highlight common challenges in the field, including questions of definition, scope, and scale for ecosystem services, as well as data collection and dissemination. We end with a summary of recommendations for moving forward.

Tidskriftsartikel (refereegranskat)abstract
- We update developments on modeling technology including unintended outputs and show how these can, at least to a large extent, be incorporated in a network model framework. Recently there have been efforts to specify more detailed models which include multiple functions to separately capture intended and unintended products. Yet another recent strand of the recent literature has also explicitly tried to include a material balance condition in the model. We see this general evolution as beginning with what might be called a black box technology, with inputs entering the box, and good and bad outputs exiting the box. The more sophisticated models can be thought of as filling in the black box with the more detailed processes involved with production, prevention and abatement, with production accompanied by undesirable byproducts subject to legal regulations and laws of nature. This can be modeled as a network within the black box.
