For the transport sector to become more sustainable, substantial technological and behavioural changes are required. Increased understanding about household choices related to more green alternatives in transportation is needed in order for policy makers to make efficient policies in the future. The main purpose of this paper is to analyze which factors that determines the fuel choice between ethanol and gasoline for owners of flex-fuel vehicles (FFVs). We evaluate how the self-reported fuel choice is influenced by the relative price, as well as individual differences in norms and perceptions about environmental and quality attributes of ethanol. Data was collected through a survey sent to Swedish FFV owners and is analyzed in a binary choice and a LCM framework. Results show that price, perceptions about quality, age and environmental attitudes influence the self-reported willingness to choose ethanol. Furthermore, results show that preferences are not homogenous, three groups are identified; price conscious respondents, ethanol skeptical respondents and respondents with pronounced environmental concern. However, although the motive for introducing and subsidizing ethanol was to reduce climate and environmental impacts, the group that chooses ethanol based on climate and environmental motives is small. The results further reveal that the debate about motor damages from ethanol have had a long lasting effect on the willingness to choose ethanol. Thus, it is necessary to try to prevent or mitigate concerns regarding e.g. potential technical or ethical issues when promoting future technologies or fuels aimed at a sustainable transportation sector.

The chemical stabilization, or immobilization, of trace elements (metals and metalloids; TE) in contaminated soil has been studied for decades. A vast number of scientific publications are available on the method performance in laboratory settings, reporting that the application of various soil amendments to contaminated soil reduces TE mobility, bioavailability and toxicity. The most commonly used soil amendments include organic matter, iron oxides, phosphates, ashes, and lately biochar, alone or in combination with each other and/or lime. Most of the implemented field studies show a certain degree of improvement in soil and/or vegetation status following amendment. Regardless the positive performance of the technique in the laboratory, field validations and demonstrations remain scarce. The establishment of a field experiment often involves permits from authorities and agreements with site owners, both of which are considerably more time-consuming than laboratory tests. Due to conservative institutional structures, public authorities have been slow to adopt alternative remediation technologies, especially when the total TE concentration in soil remains the same and all of the associated risks are not yet convincingly described. For this reason, researchers should also focus on enhancing public knowledge of alternative remediation techniques so that future projects which aim to demonstrate the effectiveness of in situ immobilization techniques under natural conditions will be supported.

Events that change the global economy rapidly, without warning, in principle strongly affect mining, which is one of the pillars of global development. After the first months of the Covid-19 pandemic, the mining pillar seems to be relatively stable. In this study, thanks to the meeting of an international team, it was possible to collect and compare a set of data on the impact on mining. In contrast to the general assessments of the stability of the mining sector, the authors decided to assess the impact of Covid-19 at individual stages of the mining project life cycle. In this way, it was possible to identify the most impacted fragments of the mining pillar. It was assessed that the highest influence of Covid-19 is observed in projects implementing feasibility studies and in projects for the development of new mines. The same is true of extracting residual resources in mines prior to the closure decision. The medium impact was confirmed at the exploration and discovery stage. The authors conclude that the impact on the current mining production is smaller and the effects in this case are short term, which is mainly due to a continued strong demand for minerals in China, which has balanced the weaker demand in other parts of the world. On the other hand, stopping the exploration and development of new mines will have a long-term impact, including an increased possibility of disruption of the future security of supplies of raw materials.

The 2010s have been a dramatic period for most primary commodity markets. Producers suffered heavily as prices fell in response to new supply facilities going into production, juxtaposed against disappointing demand evolution from China in particular, marking the end of the most powerful and enduring commodity boom since the Second World War. This book is a guide to the primary commodity universe, an increasingly crucial part of the world economy. In this updated edition, Marian Radetzki and Linda Wårell introduce and explain pertinent issues surrounding international commodity markets, including the importance of fossil markets among commodities, price formation, price trends, the shift in primary commodity consumption towards Asia, the increasing reliance on commodity exchanges, new relaxed attitude towards depletion, cartel action, and the revival of nationalism and state ownership. This is an accessible read for graduates, academic researchers, and professionals in the mineral and energy sectors.

This paper performs a quantitative analysis of iron ore prices, and is an extension of Warell (2014), which analyzed the change in iron ore pricing regime on iron ore prices using data from 2003 un ...

The way in which mining contributes to job opportunities in the region where it takes place has become increasingly important for the industry’s relations to the local community. The employment impacts of mining are however far from straightforward to assess. Considering these uncertainties about real-life job impacts, it is vital that there are sound assessments of these employment effects. The purpose of this paper is to apply a novel econometric approach to assess mining-induced job multipliers in the empirical context of northern Sweden. This analysis employs data on the number of employees in selected non-mining sectors and in the mining sector, respectively, and covering the relatively recent mining boom period (2003-2013). We also highlight differences across the two main mining counties in northern Sweden. The results show a positive statistical relationship between increases in the number of employees in the mining sector and changes in the number of employees in other sectors. The private services sector is particularly affected, while the industrial sector also benefits in the specific case of mining municipalities. The results also indicate relatively large inter-county differences, in turn highlighting the importance of addressing the context-specific circumstances when estimating the employment effects of mining.

This paper performs a quantitative analysis of iron ore prices. The analysis will focus on two general issues. First, are prices more volatile before or after the introduction of spot market pricing in 2008/2009? Second, has the change in pricing regime had a significant effect on the iron ore price? The quantitative analysis uses monthly data between January 2003 and August 2012. The overall results show that when including transportation costs to the price series we do not find that iron ore prices are more volatile after the introduction of spot market pricing. Furthermore, the change in pricing regime does not have a significant impact on the iron ore price in the econometric model. Iron ore prices, GDP growth in China, and the freight rates are found to be cointegrated (when regressed with a market dummy variable), and the short run results indicates that GDP growth in China has the strongest impact on the iron ore price series for the period tested.

Considering the past few years rapid increase in the demand for minerals and metals, mainly stemming from the strong economic growth in China and India, an understanding of the historical development of steel demand is of importance. The purpose of this paper is to analyze the trends and developments of steel consumption in the world by applying the so-called Intensity-of-Use (IoU) method. The empirical analysis is performed using steel consumption and GDP (in constant 2005 US Dollars) data for 61 countries over 42 years. The results show that the IoU hypothesis does not hold for the whole panel, but when dividing the sample into three income groups we find that the IoU hypothesis holds for the Middle income group, indicating that the countries in this income group have experienced the move from an industrialization phase towards a more service based economy in the time period investigated. However, when taking into account time series properties and applying panel unit root tests, the variables are confirmed as non-stationary. A panel cointegration test shows further that the variables are cointegrated, and an ECM model has been performed to test the IoU hypothesis. The results confirm that the IoU hypothesis holds for the Middle income group. Regarding the estimated turning point this is identified at a GDP per capita level of about 19,000 US. There are thus many countries that are far from the level of GDP per capita when steel IoU starts to decline. However, conclusions regarding the turning point should be made with caution.

The purpose of this paper is to analyze long-run electricity demand behavior in the Swedish mining industry with special emphasis on the impact of energy prices and private research and development (R & D) on electricity use. Methodologically, we estimate a generalized Leontief variable cost function using a panel data set of nine mining operations over the time period 1990–2005. Since the lower boundary of a set of short-run cost functions confines the long-run cost function, we can compute the long-run own- and cross-price elasticities of electricity demand. The empirical results indicate that long-run electricity demand in the mining industry is sensitive to changes in the own price, and already in a baseline setting Swedish mining companies tend to allocate significant efforts towards improving energy efficiency, in part through private R & D. From a policy perspective, the results imply that taxes (and tax exemptions) on electricity can have significant long-run impacts on electricity use. Moreover, future evaluations of so-called voluntary energy efficiency programs must increasingly recognize the already existing incentives to reduce energy use in energy-intensive industries.

The objective of this paper is to analyze electricity demand behaviour in the Swedish pulp and paper industry in the context of the increased interest in so-called voluntary energy efficiency programs. In these programs tax exemptions are granted if the participating firms carry out energy efficiency measures following an energy audit. We employ a panel data set of 19 pulp and paper firms, and estimate both the own- and cross-price elasticities of electricity demand as well as the impact of knowledge accumulation following private R&D on electricity use. The empirical results show that electricity use in the Swedish pulp and paper industry is relatively own-price insensitive, and the self-reported electricity savings following the voluntary so-called PFE program support the notion of important information asymmetries at the company level. However, the results display that already in a baseline setting pulp and paper firms tend to invest in private R&D that have electricity saving impacts, and our model simulations suggest that up to about one-third of the industry sector's self-reported electricity savings in PFE could be attributable to pure baseline effects. Future evaluations of voluntary energy efficiency programs must increasingly recognize the already existing incentives to reduce energy use in energy-intensive industries.

The purpose of this paper is to analyse the possible effects of introducing TPA in district heating networks by identifying and scrutinizing a number of possible scenarios for increased competition. The analysis builds on a theoretical discussion of economic efficiency in district heating operations, and the possible impacts on consumer prices of a market opening. An important conclusion is that regulated TPA may have small positive effects on competition, and at the same time it can have a negative impact on the possibility to run the integrated district heating operations in a cost-effective manner. This conclusion stems in part from the observation that most district heating networks are local in scope. Moreover, district heating operations are highly interdependent in, for instance, that the level of the return temperature of the water will affect the efficiency of combined heat and power plants. For these reasons, the introduction of the so-called single-buyer model or, perhaps even more preferable, an extended and more transparent producer market could represent more efficient market designs. Moreover, in networks with clear natural monopoly characteristics an ex ante price regulation must be considered.

The purpose of this paper is to estimate and analyse the price and welfare effects from the mergers between Rio Tinto and North Ltd. in 2000, and CVRD and Caemi in 2001. The analyses are conducted using a merger simulation model that, based on the pre-merger situation estimates the post-merger outcome. This paper applies a standard Cournot framework model where each firm produces a single homogenous product, and the firms’ strategic variable is quantities. The results from the merger simulation regarding the Rio Tinto/North Ltd. merger show that the merged firm has a combined market share of almost 20%. The estimated price increase due to the merger is 5.8%. Regarding the CVRD/Caemi merger the initial concentration in the pre-merger market is substantially larger than the year before, and the results indicate that the estimated price effect from the merger is more significant, almost 7%. Regarding the effect of prices on resource extraction, the estimated higher price of iron ore after the merger implies that substitution towards steel scrap in the steel-making process increases. This finding implies that resource extraction possibly has been lower than what might have been the case without the merger. Note that this effect is analysed as ceteris paribus, i.e., other impacts on iron ore demand and prices than the specific mergers have not been considered. In both merger simulations the overall welfare effect is estimated to be negative, something which thus does not support the European Commission's decisions to allow these mergers. However, none of the simulations did take into account possible cost efficiencies resulting from the mergers.

The purpose of this paper is to estimate and analyse the price effects of the iron ore mergers between Rio Tinto and North Ltd in 2000, and CVRD and Caemi in 2001. The analyses are conducted using a merger simulation model that, based on the pre-merger situation, estimates the post-merger outcome. This paper applies the so-called proportionality-calibrated almost ideal demand system (PCAIDS) model, which assumes that the product is differentiated and that the strategic variable is price. The results from the merger simulations show that in the case of the merger between Rio Tinto and North Ltd, the merged firm has a combined market share of almost 20%. However, the estimated market weighted average price effect is only 2.6%. Regarding the merger between CVRD and Caemi, the merged firm's market share is about 29%, and the estimated market weighted average price effect is 4.6%. When removing Caemi's Canadian asset, which was the Commission decision in order to allow the merger, the market price effect decreases to 3.1%. Overall the results in this study support the Commission's decisions regarding both merger cases, and shows that merger simulations of price effects can be valuable tools in merger assessments.

Given the importance of coal in world energy supply an analysis of the relevant geographic market is essential for consumers, producers, as well as for competition policy. The purpose of this paper is to define the relevant economic market for steam and coking coal, and to test the hypothesis of single world markets for these coal products. Methodologically the paper relies on two different tests for defining markets, using both shipments data and price data. The results from both methods point in the same direction. In the case of coking coal the results indicate that the market is essentially global in scope, and also that the market has become more integrated over time. The results for steam coal show that the market is more regional in scope, and there exist no clear tendencies of increased integration over time. One policy implication of the finding that the steam coal market is more regional in scope, and thus that the market boundary is smaller than if the market would have been international, is that a merger and acquisition in this market likely would have been of a more concern for antitrust authorities than the same activity on the coking coal market.

The purpose of this paper is to test the hypothesis of the existence of a single economic market for the international coal industry, separated for coking and steam coal, and lo investigate market integration over time. This has been conducted by applying cointegration and error-correction models on quarterly price series data in Europe and Japan over the time period 1980-2000. Both the coking and the steam coal markets show evidence of global market integration, as demonstrated by the stable long-run cointegrating relationship between the respective price series in different world regions. This supports the hypothesis of a globally integrated market. However, when analyzing market integration over time it is not possible to confirm cointegration in the 1990s for steam coal. Thus, compared to the coking coal market, the steam coal market looks somewhat less global in scope. Validerad; 2006; 20061010 (evan)
