    Evaluating the efficency of the global primary aluminium smelting industry: a data envelopment approach2011Inngår i: Mineral Economics, ISSN 2191-2203, E-ISSN 2191-2211, Vol. 24, nr 1, s. 29-44Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The purpose of this paper is to evaluate the efficiency of the global primary aluminum industry. Efficiency is here taken to be evaluated relative to some benchmark, i.e., the smelter or smelters identified as the most efficient in the data set, thus forming the production frontier. The performance of individual smelters, specifically their technical, allocative, and scale efficiencies are calculated by the means of data envelopment analysis. A proprietary database containing data on inputs used, output, and cost of production for 151 primary aluminum smelters operational globally in 2003 were used in the efficiency estimations. In order to assess and contrast the performance of smelters at different locations, facing dissimilar policy and factor supply environments, smelters are grouped into geographical regions. Furthermore, the technology used will also be evaluated in terms of the above efficiency measures. For each region, measures of potential technical and cost-wise factor savings will be calculated in order to assess specifically in what way production factors improvements can be made and approximately how large these improvements are. The findings indicate that; (a) smelters are overall highly efficient given the scale of operation, (b) many smelters operate with increasing returns to scale and thus we find significant scale inefficiencies, (c) substantial allocative inefficiencies exist within the industry, and (d) there are significant variations in the level of efficiency across regions. The allocative efficiency is particularly low in regions such as China and the Commonwealth of Independent States (CIS) region. Finally, the greatest potential for factor reductions is in labor input in China, the CIS region and in Asia.

    The expanding global income gap: how reliable is the evidence?2002Inngår i: European Journal of Development Research, ISSN 0957-8811, E-ISSN 1743-9728, Vol. 14, nr 1, s. 243-263Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Employing exchange rate determined per capita GDPs, the paper demonstrates a very sharp increase in global income inequality. In 1960, the gap between country groups representing the poorest & richest population deciles equaled 40, & there were widespread fears that the large income gap was a threat to sustainable global economic expansion. By 1995, the poor group per capita incomes had declined by almost 50% in real terms, & the gap had widened to 140. These findings are in sharp contrast to the results from the increasingly fashionable assessments employing PPP-adjusted income figures. The latter show a positive income trend for the poorest decile, & an insignificant increase in the rich/poor income gap. It is well known that exchange rate determined international GDP comparisons exaggerate the income gaps between rich & poor nations. But it is far from obvious that PPP adjustments yield results that are superior to those obtained with the help of exchange rates, when the relative gaps are compared at different points in time, or when per capita incomes are tracked over long time periods in individual countries or country groups. Our dramatic results, therefore, represent a very important second opinion on what has happened to global income distribution. 9 Tables, 2 Figures, 29 References. Adapted from the source document

    Natural gas in the Asian Pacific region: market behavior and the Japanese electricity market2001Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This dissertation consists of four main chapters, all related to the Asian Pacific natural gas market, and the role of the Japanese electricity sector. The natural gas market in Asia Pacific is heavily dependent on the demand from Japan, which imports around 75% of the gas traded as LNG (liquefied natural gas) in the region. The demand for natural gas in Japan is, in turn, almost exclusively driven by the electricity industry that consumes around 70 % of the imported natural gas. On the supply side we find seller concentrations with only six countries exporting LNG in the region. The first main chapter analyzes the market structure of the Asian Pacific natural gas market, the next two relate to the usage of natural gas in the Japanese fossil-fueled electricity production, and the final study investigates the demand for electricity in the residential sector in Japan. The first chapter argues that the buyers in Japan, through cooperation, have the potential to exert the market power that their large market share provides them with. This could be offset by the monopoly power that the six present sellers have. In the chapter four, the solutions for the four imperfect competition cases of, monoposony, monopoly, bilateral monopoly, and the Cournot model are simulated. Neither of the model solutions comes close to the both the actual market price, and the actual gas volumes. The model that best mimics the actual price is the bilateral monopoly model, while the monopsony model comes closest to the actual volumes. Giving some mixed evidence of how the Asian LNG market works. Given the indication of market power, the second study analyzes the fossil-fuel mix efficiency in the power sector in Japan. If the power sector is able to exert the alleged market power, it may be the case that they minimize costs according to shadow prices instead of actual market prices. Such behavior could cause the fossil-fuel mix used for power generation to be inefficient. The analysis is based on a Translog model that assumes cost minimization according to shadow prices, instead of actual market prices. Given this assumption, relative price efficiency with respect to the fossil-fuel mix is tested. The results from the model indicate that the null hypothesis of relative price efficiency in the fossil-fuel mix cannot be rejected. Hence, if the Japanese LNG buyers exercise some market power in the LNG market the model provides no evidence for the notion that they use natural gas efficiently, relative other fossil fuel, in electricity generation. The third chapter analyzes the impact that Japanese energy policy has had on the fossil-fuel choice in the power industry in Japan. Due to energy security and environmental concerns, the energy policy in Japan has been favoring natural gas as fuel in fossil-fueled electricity production. The study uses a restricted flexible cost function approach to analyze the impact on fuel costs when the volume of natural gas is exogenous – due to the energy policy – to the electricity producer’s choice of fossil-fuel mix. By deriving the shadow price of natural gas, the optimal (cost minimizing) consumption of natural gas is estimated. The results indicate that too much gas is used. Hence, the fossil-fuel mix is inefficient from a pure cost perspective. The results also shows that short-term substitution between the unrestricted fossil-fuels – coal, crude oil, and fuel oil - have occurred, illustrated by negative own-price, and positive cross-price elasticities of reasonable magnitude. The study also shows that the combination of technological change and energy policy has been fuel-saving with respect to crude oil, and fuel-using for coal and fuel oil in fossil-fueled electricity production. The fourth chapter uses an error-correction model to estimate long- and short-run electricity demand elasticities in the residential sector in Japan. The results show low long-run price elasticities, indicating that the proposed deregulation of the electricity sector in Japan –with projected lower prices – will have a relatively low impact on the electricity demand in the residential sector.

    The Russian coal industry in transition: a linear programming application2001Inngår i: OPEC Review, ISSN 0254-3958, Vol. 25, nr 1, s. 53-78Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper analyses the restructuring of the Russian steam coal market. The main purpose is to compare the prevailing steam coal flows between mine basins and electric utilities and the actual coal prices with those that would prevail in an efficient market. The analysis is done within a short-run linear programming model. Coal demands and supplies are identified. The objective function that is minimised consists of the delivered costs, i.e. extraction plus transportation costs, subject to exogenous demand requirements and capacity restrictions. We conclude that, in spite of attempted restructuring, the Russian coal steam coal market is still highly inefficient. This is mainly due to the fact that large amounts of coal are delivered over very long distances, a pattern that often cannot be justified in economic terms. Because of cost-inefficient coal deliveries and large subsidies, coal prices are also highly distorted. Given the communist legacies of the past, the restructuring process will probably take considerable time and is unlikely to be successful until there is a fundamental change in the economic and political institutions.

    Elements of the Asia Pacific gas market: market power and efficiency1999Licentiatavhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    Natural gas trade in the Asian Pacific market is heavily dependent on the demand from Japan, which imports around 75% of the gas traded as LNG (liquefied natural gas) in the region. This study argues that the buyers in Japan, through cooperation have the potential to exert the market power that their large market share provides them with. The study adopts a monopsony model, which suggests that Japanese buyers to some extent exercise their market power. The optimal price indicated by the adopted model is higher then the actual price, which would indicate that Japan, has used its market power. Given the indication of market power, the second part of the thesis analyzes the fossil fuel mix efficiency in the power sector in Japan. The analysis is based on a model that has cost minimization according to shadow prices, not actual market prices, as basic assumption. Given this assumption relative price efficiency with respect to fossil fuel mix is tested. The results from the model do not give any support to reject the hypothesis of relative price efficiency in the fossil fuel mix. Hence, if the Japanese LNG buyers exercise any market power they despite that uses natural gas efficiently, relative the price of other fossil fuel, in their electricity generation.
