Are the Energy Efficiency Technologies efficient?

This paper investigates a rather neglected issue regarding the impact of Energy Efficiency Technologies (EETs) on firms' productive performance. Possible influences may arise in the context of internal cost of adjustment, learning by doing effects and the capital vintage. A unique dataset was used which has resulted from a survey carried out among a sample of Greek EET adopters in the manufacturing sector. An econometric framework based on nested non-neutral frontiers, was developed to estimate the influence and the decomposition of EETs on firms' productive performance. The empirical findings reveal that the EETs affect positively the firms' technical efficiency and negatively the deterministic part of the frontier. Significant variations among industries and size groups appear to be present. Some policy implications are derived based on the empirical evidence supporting a mix of energy and technology directions.

Regulatory ‘Balancing’ and the Efficiency of Green R&D

We identify and analyse several dynamic implications of setting environmental standards such as to balance marginal costs and benefits. The adoption of such a regulatory approach is shown to effect (i) the speed of improvement of abatement technologies; (ii) the direction (in a sense to be defined) of that improvement; (iii) its source and the distribution of the rents from it; and (iv) the rate of development of defensive (averting) technologies. Existing views are thoroughly synthesised in the context of a simple diagrammatic model, several new results are derived and at least one conventional wisdom questioned. The message of the analysis for legislators and regulators is that cost–benefit balancing should be done with care.     

On Efficiency of the Compulsive Institution in the Environment Governance

Limited by the condition of information, technology and natural elements, the compulsive institutions in the environment governance can not form a “hard constraint” to the individuals. Because of the individual‘s speculative behaviors, the government‘s deviation from its environmental governance, and the non-cooperative game between individuals and the legal organization, the implementation of the compulsive institutions is not as good as being expected. Through analyzing the mechanism of the compulsive institutions, this paper puts forward some suggestions to enhance the efficiency of such institutions‘ implementation.     

Performance and the Barriers of China＇s Energy Efficiency

中国政府将加快发展能源产业、坚持节约能源和保护环境作为一项基本国策。随着我国经济的不断发展,能源消费总量虽然在逐年增加,但能源利用效率却在不断提高。在中央政府政策的推动下,能源强度虽然呈下降趋势,但近年来下降的速度明显趋于平缓,低于改革开放初期。在分析总结我国能源利用效率变化的趋势和特点的基础上,通过对能源强度系数进行分解,发现能源强度变化的技术效应和结构效应都有减弱的趋势,尤其是结构效应。在此基础上从经济发展和社会因素两方面,进一步探讨了阻碍我国能源利用效率进一步提升的原因。     

The Efficiency Evaluation of Commercial Banks Based on DEA/TOPSIS

This paper brings forward an efficiency evaluation method based on DEA/FOPSIS for commercial banks. To avoid the slack of output index, the difference is taken into account in the weight of different output index, mending the shortage of traditional DEA evaluation methods.     

Efficiency analysis of German electricity distribution utilities – non-parametric and parametric tests

This study applies non-parametric and parametric tests to assess the efficiency of electricity distribution companies in Germany. Traditional issues in electricity sector benchmarking are addressed, such as the role of scale effects and optimal utility size, as well as new evidence specific to the situation in Germany. Labour, capital, and peak load capacity are used as inputs, and units sold and the number of customers as output. The data cover 307 (out of 553) German electricity distribution utilities. A data envelopment analysis (DEA) is applied with constant returns to scale (CRS) as the main productivity analysis technique, whereas stochastic frontier analysis (SFA) with distance function is the verification method. The results suggest that returns to scale play but a minor role; only very small utilities have a significant cost advantage. Low customer density is found to affect the efficiency score significantly, in particular in the lower third of all observations. Surprisingly, East German utilities feature a higher average efficiency than their West German counterparts. The correlation tests imply a high coherence of the results.     

Efficiency and productivity in the Indian unorganized manufacturing sector: did reforms matter?

This paper analyzes total factor productivity growth of the unorganized manufacturing sector in India using several rounds of the large scale national sample survey state level data for 15 major Indian states for the period 1978–1979 to 2000–2001. Data envelopment analysis is used to compute Malmquist total factor productivity index and its components. The impact of economic reforms on efficiency and productivity is examined. Evidence suggests that total factor productivity registered a positive growth during the period in the country as a whole. Most states in the country witnessed higher total factor productivity growth in the post 1990s reforms period than in the pre-reforms period. Decomposition of the Malmquist productivity index shows that improvement in technical efficiency rather than technical progress had contributed to the observed acceleration in the growth rate. Econometric analysis of the determinants of total factor productivity growth demonstrates that ownership, literacy, farm growth and infrastructure availability significantly influence total factor productivity growth in the sector.

This paper illustrates how to evaluate Comprehensive Efficiency （CE） based on Scientific Development Outlook, which reflects overall development of enterprise leaders＇ performance, depends on measuring Output Efficiency Index （OEI） and Cost Efficiency Index （CEI） of enterprise leaders＇ performance, and adopts the C^2R model in Data Envelopment Analysis （DEA）.     

An Analysis of Energy and Environment Efficiency of China’s Iron and Steel Industry

Due to heavy energy consumption and low technical efficiency, China’s iron and steel industry is trapped in the dilemma “large but not strong”. This situation not only exerts enormous pressure on energy security but also on increased carbon emission and environmental pollution. The contribution of this study is to calculate the energy and environment efficiency of China’s iron and steel industry and to analyze the factors affecting this efficiency. An index of energy and environment efficiency is introduced based on Directional Slacks-based Distance Measure Model. This index is adopted to measure the energy and environment efficiency of China’s iron and steel industry using 2,382 firm observations during 2001 to 2005. In addition, Hierarchy Linear Model (HLM) is applied to analyze the factors which can influence the efficiency with both firm-level and province-level data. The conclusions are as follows: The energy and environment efficiency of China’s iron and steel industry did not have a significant change during the research period. A firm’s age, size, ownership, product category and the economy of its province have significant influence on its energy and environment efficiency.     

Uncertainty and the Value of Capital: Marginal Efficiency and the ‘Conventional Projection’

Keynes provided not one but two formulae for calculating the relationship between the Present and the Future. On the one hand we have the well-known Marginal Efficiency of Capital (MEC), where the value of the present stock equals the discounted sum of future earnings, but on the other we have the Conventional Projection (CP) where the expected earnings in the future reflect the productivity of present facilities. The MEC is likely to reflect the views of fund managers, the CP the views of corporate managers. These two sets of judgments of the future may coincide or diverge. Either way they determine the value of the present capital in terms of claims to it—and this determination may be stable or unstable, but in any case will be volatile in the sense that the underlying uncertainty can lead to rapid shifts. By contrast, the Classical Equations will give us the value of present capital in terms of its replacement or real cost. This is reliable, being based on the real side of the economy. The ratio of this to the uncertain and volatile MEC/CP financial calculation is analogous to Tobin's Q, and will play a role in determining investment decisions, but it chiefly gives us insight into how volatile those must be.     

Does Ownership or Competition Matter? The Effects of Telecommunications Reform on Network Expansion and Efficiency

I use newly released data from the International Telecommunications Union to examine the effects of privatization and competition on network expansion and efficiency. Using a fixed-effects model, I find that during the 1986-1995 time period, those countries that have at least fifty percent of the assets of their main telecommunications provider in the private sector have significantly higher main lines per 100 inhabitants and, to a lesser degree, have higher growth in main lines per 100 inhabitants. There is no evidence, however, that privatization leads to higher growth in main lines per 100 inhabitants in those countries whose GDP per capita is less than $10,000. Privatization is positively associated with main lines per employee and growth in main lines per employee. While competition is not found to affect network expansion, it is found to positively affect efficiency as measured in main lines per employee. In order to account for the possible endogeneity of the privatization and competition dummy variables, all equations are estimated using an instrumental variable approach as well.     

Conventional and Islamic Banks’ Performance in the Gulf Cooperation Council Countries; Efficiency and Determinants

This paper investigates the cost efficiency levels of the banking sectors of the Gulf Cooperation Council (GCC) countries for the period from 2001 to 2015 and provides a comparison of conventional and Islamic banks. We obtain measures of efficiency using a stochastic frontier model and the meta-frontier approach. The evidence demonstrates that Islamic banks are less efficient and have a weaker level of production technology than conventional banks. The cost efficiency of banks varies significantly across the six Gulf countries and over time. We adopt the results drawn from the meta-frontier model that allow to take into account the differences between the studied countries, and empirically examine the bank-specific, financial, macroeconomic, and political determinants of banking efficiency. The results provide evidence of the differential effects of the selected variables on the efficiency of conventional and Islamic banks. These variables affect the performance of the two types of banks in different ways and with different magnitudes.

     

Intertemporal Emission Trading with a Dominant Agent: How does a Restriction on Borrowing Affect Efficiency?

In this paper we analyze how restricting intertemporal trading by prohibiting borrowing of emissions permits affects the ability of a dominant agent to exploit its market power. We show that the monopolist could take advantage of the constraint on borrowing by not distributing the sale of permits cost-effectively across periods. Furthermore, we show that a constant present-value price over time does not imply a cost- effective distribution of abatement (permit sales) across periods.     

Measuring the Effect of Economic Growth on Countries’ Environmental Efficiency: A Conditional Directional Distance Function Approach

Using a recently developed probabilistic approach of a conditional directional distance function, we measure the effect of economic growth on countries’ environmental efficiency in carbon dioxide emissions for a sample of 99 countries over the period of 1980–2010. Our approach directly accounts for the exogenous factors influencing countries’ environmental production; therefore, we do not impose the separability condition on the estimated environmental efficiencies. When examining the entire sample as well as the sample of developed countries, our results reveal an inverted U-shaped relationship between countries’ GDP per capita and environmental efficiency. However, when examining the relationship for the sample of developing countries, the results reveal an N-shaped form. Moreover, our results show that countries ratifying the Kyoto Protocol tend to have higher efficiency scores, implying that their mitigation activity is less costly.     

Foreign Aid,Incentives and Efficiency: Can Foreign Aid Lead to the Efficient Level of Investment?

This paper develops a two‐period model in which the recipient faces borrowing constraint and the donor is a Stackelberg follower to address two important policy questions: (i) whether foreign aid can lead to the efficient level of capital investment in the recipient country and (ii) how does the form (e.g. budgetary transfers, capital transfer) and the timing of aid affect the recipient's financial savings and capital investment. It finds that the disincentive effect of the capital transfer on the capital investment by the recipient is larger than the budgetary transfers. It makes financial savings more attractive relative to the capital investment for the recipient. In the absence of capital transfer, the multi‐period budgetary transfers not only lead to the efficient level of capital investment by the recipient, but also achieve the same allocation as under commitment. The capital transfer can lead to the efficient level of capital investment, but in this case, it completely crowds out the recipient's own capital investment.     

Career Paths,Unemployment, and the Efficiency of the Labor Market: Should Youth Employment Be Subsidized?

This paper studies the implications of learning‐by‐doing on youth unemployment and market efficiency when workers benefiting from this kind of training experience search (while on the job) for a higher skill job. Firms with low‐skill jobs suffer from a poaching behavior by firms with high‐skill jobs, causing a shortage of low‐skill jobs and excessive youth unemployment. An optimal policy, consisting of taxing the output of high‐skill jobs and subsidizing the output of low‐skill jobs, restores market efficiency and reduces youth unemployment.
