Measurement of technical and allocative efficiencies using a CES cost frontier: a benchmarking study of Japanese transmission-distribution electricity

This paper estimates the technical and allocative inefficiencies of the transmission-distribution sector of Japanese electric utilities using a panel data during the 1981–1998 period. A stochastic production frontier of the CES form is jointly estimated with input demand equations. Taking advantage of the self-duality, we retrieve the cost frontier by which the impacts of technical and allocative inefficiencies on costs and input demands are measured. The estimated elasticity of substitution is significantly different from unity in favor of the CES specification over the Cobb–Douglas. The results show that observed costs are 9 to 48% higher than the efficient level; technical inefficiency raises costs by 1 to 28%, while allocative inefficiency does so by 8 to 30%. Although their impacts on costs are similar, technical inefficiency more fluctuates so the differences in the performance of utilities are mainly due to technical inefficiency. We also find a substantial over-utilization of capital for all utilities.

Estimating Mortality and Economic Costs of Particulate Air Pollution in Developing Countries: The Case of Nigeria

The value of statistical life is an essential parameter used in ascribing monetary values to the mortality costs of air pollution in health risk analyses. However, this willingness to pay estimate is virtually non-existent for most developing countries. In the absence of local estimates, two major benefit transfer approaches lend themselves to the estimation of the value of statistical life: the value transfer method and the meta-regression analysis. Using Nigeria as a sample country, we find that the latter method is better tailored than the former for incorporating many characteristics that vary between study sites and policy sites into its benefit transfer application. It is therefore likely to provide more accurate value of statistical life predictions for very low-income countries. Employing the meta-regression method, we find Nigeria’s value of statistical life estimate to be $489,000. Combining this estimate with dose response functions from the epidemiological literature, it follows that if Nigeria had mitigated its 2006 particulate air pollution to the World Health Organisation standards, it could have avoided at least 58,000 premature deaths and recorded an avoided mortality related welfare loss of about $28 billion or 19 % of the nation’s GDP for that year.     

Armington elasticities in intermediate inputs trade: a problem in using multilateral trade data

Abstract.  In this paper we find that the estimates of Armington elasticities (the elasticity of substitution between groups of products identified by country of origin) obtained from multilateral trade data can differ from those obtained from bilateral trade data. In particular, the former tends to be higher than the latter when trade consists largely of intermediate inputs. Given that the variety of intermediate inputs traded across borders is increasing rapidly and that the effect of this increase is not adequately captured in multilateral trade data, the evidence shows that the employment of multilateral trade data to estimate Armington elasticities needs caution.

The Effects of Tolerance for Ambiguity and Task Uncertainty on the Balanced and Combined Use of Project Controls

This study contributes to the literature by examining antecedents to different combinations of management control systems. These combinations include combined use, focusing on the absolute magnitude of the project manager's organic and mechanistic control activities, and the balanced use, that is their relative magnitude. It is proposed that project managers' perceived task uncertainty and tolerance for ambiguity have direct and interaction effects on their balanced and combined use of different combinations of project control. Consistent with the hypotheses, the results show negative relationships between high tolerance for ambiguity and balanced and combined use of organic and mechanistic controls. Further, task uncertainty appears to have a direct, significant negative effect on balanced use, but not on combined use. Furthermore, as proposed, a negative significant interaction effect was found. The results were controlled for project size, project type and level of innovativeness.     

A multi-division efficiency evaluation of U.S. electric power companies using a weighted slacks-based measure

Prior to the 1990s, the electric power industry was highly regulated across the world. Under a liberalization policy to open markets and to grow competition commenced in the early 1990s, efficient management has become a necessity for companies in this industry. The current study examines the divisional efficiencies of multi-functional, vertically integrated companies seeking to optimize their overall management efficiency. For this purpose, divisional cost data are used as input into a slacks-based measure (SBM) model. This provides divisional efficiency indices based on slacks, as well as one for the larger firm-level management function. Further, given the important role of cost structure, we introduce a modified SBM, named the weighted SBM (WSBM), which directly incorporates division-specific weights into the objective function. Results reveal that the power generation divisions of the companies studied have significant influence on the overall cost, whereas the impact of the other four divisions - transmission, distribution, sales and general administrative - is limited.     

Evaluating a Framework for Multi-Stakeholder Decision Support in Water Resources Management

In this paper we describe a framework for multicriteria modeling and support of multi-stakeholder decision processes. We report on its testing in the development of a new water level management policy for a regulated lake-river system in Finland. In the framework the stakeholders are involved in the decision process from the problem structuring stage to the group consensus seeking stage followed by a stage of seeking public acceptance for the policy. The framework aims at creating an evolutionary learning process. In this paper we also focus on the use of a new interactive method for finding and identifying Pareto-optimal alternatives. Role playing experiments with students are used to test the practical applicability of a negotiation support procedure called the method of improving directions. We also describe the preference programming approach for the aggregation of the stakeholder opinions in the final evaluation of alternatives and consensus seeking.     

Branding Strategies of Born Globals

Born global companies have now been studied for a decade. However, little has been written specifically about the challenges facing born globals in their branding endeavours. This research examines the branding strategies of 30 Finnish small and medium-sized born globals. The experience, qualities and global orientation of the founder and the top management team are found important for the success of the born globals in their branding achievements. A key argument is that business-to-business and business-to-consumer born globals differ as to their branding strategies and approaches. The analysis reveals a major imperative; branding strategies are dynamic and depend on the globalisation degree.     

Equity premium in Finland and long-term performance of the Finnish equity and money markets

Using new monthly series collected together for the first time for Finland, this paper analyses the performance and development of the Finnish equity and money markets as well as the equity premium and inflation from 1912 to 2009. The series are analyzed and compared to similar series from Sweden and USA. Continuously compounded nominal returns in Finland have been high, 12.91 and 6.44 % per annum for the stock and money markets, respectively. However, taking into account the high annual average inflation rate of 7.77, the Finnish market has provided clearly lower real returns than the US market. On the other hand, the equity premium, 10.14 % per annum, is found to be comparable to that of the United States (9.35 %) and higher than that in Sweden (6.01 %) using an approach similar to Mehra and Prescott (Handbook of the economics of finance, vol 1B. Financial Markets and Asset Pricing, North Holland, 2003). Finally, our empirical evidence suggests that as the Finnish stock market has matured, it shows an increasing degree of informational efficiency while at the same time becoming more intertwined with international markets.     

Using Choice Experiments to Value the Natura 2000 Nature Conservation Programs in Finland

This paper is concerned with the preferences of the Finnish households for a controversial nature conservation program – the European Union's Natura 2000 Network. Since the program was mainly based on biological considerations, it met strong public opinions from different interest groups in Finland. Using the choice experimental method, we attempt to estimate the values that the Finnish households would place on different preservation levels. It is found that the mean willingness to accept for a decrease in the nature preservation area is much greater than the mean willingness to pay for an increase by the same amount. Also, the marginal willingness to pay becomes zero after an initial increase in the natural preservation area, which is consistent with our earlier findings in a binary choice valuation study. Policy implications of these results are also discussed in relation to different decision criteria.     

Eco-efficiency analysis of consumer durables using absolute shadow prices

We develop a method for eco-efficiency analysis of consumer durables that is based on Data Envelopment Analysis (DEA). In contrast to previous product efficiency studies, we consider the measurement problem from the policy perspective. The innovation of the paper is to measure efficiency in terms of absolute shadow prices that are optimized endogenously within the model to maximize efficiency of the good. Thus, the efficiency measure has a direct economic interpretation as a monetary loss due to inefficiency, expressed in some currency unit. The advantages as well as technical differences between the proposed approach and the traditional production-side methods are discussed in detail. We illustrate the approach by an application to eco-efficiency evaluation of Sport Utility Vehicles.
