the interdependence of european russian energy relations abstract the aim of this article is to explore this dynamic interdependent relationship between russia and europe in the field of energy based on the concept of interdependence and perspectives on the political aspects of trade relations we discuss how russia can exercise power based on its energy resources and how the eu can compensate for its lack of power in the energy game with other trade related capabilities in particular we explore the implications of the lack of a full fledged eu foreign energy policy towards russia with the somewhat counter intuitive conclusion that the eu countries on average not necessarily are better off with a common foreign energy policy

who governs energy the challenges facing global energy governance this article conceptualizes the energy problems facing society from a global governance perspective it argues that a notion of global energy governance taken to mean international collective action efforts undertaken to manage and distribute energy resources and provide energy services offers a meaningful and useful framework for assessing energy related challenges the article begins by exploring the concepts of governance global governance and global energy governance it then examines some of the existing institutions in place to establish and carry out rules and norms governing global energy problems and describes the range of institutional design options available to policymakers it briefly traces the role of a selection of these institutions from inter governmental organizations to summit processes to multilateral development banks to global action networks in responding to energy issues and points out their strengths and weaknesses the article concludes by analyzing how the various approaches to global governance differ in their applicability to addressing the conundrums of global energy problems

price indexes inequality and the measurement of world poverty i discuss the measurement of world poverty and inequality with particular attention to the role of purchasing power parity ppp price indexes from the international comparison project global inequality increased with the latest revision of the icp and this reduced the global poverty line relative to the us dollar the recent large increase of nearly half a billion poor people came from an inappropriate updating of the global poverty line not from the icp revisions even so ppp comparisons between widely different countries rest on weak theoretical and empirical foundations i argue for wider use of self reports from international monitoring surveys and for a global poverty line that is truly denominated in us dollars

can poor consumers pay for energy and water an affordability analysis for transition countries low income households spend a substantial share of their income on utility services such as electricity heating and water the difficulty of these socially vulnerable consumers to absorb further price increases is often used as an argument against tariff reform however detailed quantitative information on the affordability of tariff adjustments for low income consumers is actually quite scarce much of the available information is based on households this paper takes a more detailed look at the affordability of electricity district heating and water for low income consumers in transition countries while the available data are incomplete the paper finds that affordability is a problem for low income consumers in most countries in particular in the water sector and in the commonwealth of independent states cis the affordability consequences of tariff reform ultimately depend on the speed of tariff adjustments relative to the growth in household income the level of tariffs needed for cost recovery the level of effective tariffs at the outset tariffs adjusted for non payment and the demand response to the tariff increase the paper finds that delaying tariff reform by a few years makes little difference to affordability constraints and may therefore not be an effective way to mitigate the social impact of utility reform

measuring the energy security implications of fossil fuel resource concentration abstract economic assessments of the welfare effects of energy insecurity are typically uncertain and fail to provide clear guidance to policy makers as a result governments have had little analytical support to complement expert judgment in the assessment of energy security this is likely to be inadequate when considering multiple policy goals and in particular the intersections between energy security and climate change mitigation policies this paper presents an alternative approach which focuses on gauging the causes of energy insecurity as a way to assist policy making the paper focuses on the energy security implications of fossil fuel resource concentration and distinguishes between the price and physical availability components of energy insecurity it defines two separate indexes the energy security price index espi based on the measure of market concentration in competitive fossil fuel markets and the energy security physical availability index espai based on the measure of supply flexibility in regulated markets the paper illustrates the application of espi and espai with two case studies france and the united kingdom looking at the evolution of both indexes to 2030

oil vulnerability index of oil importing countries abstract this paper assesses the relative oil vulnerability of 26 net oil importing countries for the year 2004 on the basis of various indicators the ratio of value of oil imports to gross domestic product gdp oil consumption per unit of gdp gdp per capita and oil share in total energy supply ratio of domestic reserves to oil consumption exposure to geopolitical oil market concentration risks as measured by net oil import dependence diversification of supply sources political risk in oil supplying countries and market liquidity the approach using the principal component technique has been adopted to combine these individual indicators into a composite index of oil vulnerability such an index captures the relative sensitivity of various economies towards developments of the international oil market with a higher index indicating higher vulnerability the results show that there are considerable differences in the values of individual indicators of oil vulnerability and overall oil vulnerability index among the countries both inter and intraregional

evaluating energy security in the asia pacific towards a more comprehensive approach the energy security conundrum how to equitably provide available affordable reliable efficient and environmentally benign energy services is a technology and policy challenge perhaps unlike any other the recent article on an energy security in the asia pacific by vlado vivoda is an excellent starting point for how to best capture the unique energy security challenges facing the region this article builds on vivoda s work but also points out some shortcomings with his analysis

the renminbi and poor country growth discussions on how best to exit from global imbalances to create a more balanced world economy have ignored the impact on poor countries of proposals to redress these imbalances this paper aims at filling that gap it gauges the degree of renminbi rmb undervaluation presents evidence on rmb undervaluation and china s gdp growth rate surveys the role of the real effective exchange rate both its level and its stability over time for underpinning growth in developing countries especially in large dual economies such as china and india finally the paper presents new evidence on growth linkages between china and poor countries for the last two decades and surveys literature on potential displacement effects of rmb appreciation the analysis allows broad conclusions to be drawn about the potential developing country beneficiaries and losers from various renminbi adjustment scenarios in the forthcoming years

defining energy security takes more than asking around abstract in undetermined the recent contribution by benjamin sovacool proposes 20 dimensions and 320 indicators of energy security in asia however the method for identifying these dimensions and indicators 64 semi structured interviews has three shortcomings first asian policy makers responsible for energy security are absent from the pool of respondents dominated by academics second no prioritization or contextualization of energy security concerns is attempted leading to an excessively long generic list third no disagreements between the interviewed experts are accounted for future attempts to define energy security based on perceptions should involve relevant social actors include mechanisms for discriminating between primary and secondary concerns and find ways to constructively report on disagreements less

quantifying the supplier portfolio diversity of embodied energy strategic implications for strengthening energy resilience this paper investigates energy resilience of countries by quantifying the supplier diversification of both direct and embodied energy import in particular we quantify two approaches to diversify a country s supplier portfolio by lowering the dependency on each supplier portfolio diversification and by having embodied energy suppliers that are different from its direct energy suppliers portfolio differentiation we examine possibilities for strategic utilization of embodied energy trade to compensate for low diversity of direct energy trade for three types of fossil resources coal oil and gas we find that the diversity of embodied energy import is much greater than that of direct energy import of the three energy resources coal enables countries to adopt portfolio diversification and portfolio differentiation more than gas and oil our results suggest embodied energy can be considered as a transfer of energy resources across national borders that can directly benefit from the diversity of the world energy production by skipping the limited diversity of the world energy export

chinese energy investments in europe an analysis of policy drivers and approaches abstract enhancing the understanding of china eu energy relations the article examines chinese energy investments in europe from 2008 to 2015 and analyzes the energy interests and policy approaches underpinning them analysis of this data shows that within the eu 30 chinese investments largely focused on the oil and gas sector especially through the acquisition of company shares chinese energy investments in europe reflect a clear political and commercial strategy that addresses the prc s need to balance supply chain security of fossil fuels environmentally friendlier energy production and use as well as to enhance the market position and energy industrial capabilities of chinese state owned or state supervised energy companies based on a comprehensive set of domestic incentives for international investment the chinese penetration of the european energy sector is embedded within two levels of political cooperation the first level revolves around bilateral investment agreements between china and 27 eu member states on the second level china and the eu have established a variety of formats that guide their energy cooperation the conclusion of the proposed bilateral investment agreement between the prc and the eu would create a uniform investment environment across the continent and facilitate mutual economic benefits for both parties

credit union policies and performances in latin america this paper presents a conceptual framework for explaining credit unions cus loan delinquency and profitability in developing countries it also offers an empirical estimation for a unique sample of cus in latin america

on measuring energy poverty in indian households summary the relationship between energy and poverty is obvious and goes both ways recognizing this this paper provides a short overview of different approaches to measuring energy poverty it then presents a novel two dimensional measure of energy poverty and energy distribution that combines the elements of access to different energy types and quantity of energy consumed an assessment of the extent of energy poverty and changes in energy distribution pattern are analyzed by applying this measure to indian household survey data for 1983 2000 the analysis shows a significant reduction in the level of energy poverty and a rapidly developing subcontinent the new measure is a good complement to conventional monetary measures and is general enough to be applied to other developing countries

european energy policy a review this article presents the implemented policies of the european union in the broader field of energy and provides a picture of the union s strategy on energy related issues a brief historical background is provided covering the period from the beginning of the union s creation in 1951 when coal was considered as the heart of its economic growth up to 2012 policy development principles as well as the consultations that take place before the proposal of each option are also discussed implemented policies are classified into seven broad categories renewable energy energy efficiency and savings internal energy markets security of energy supply environmental protection nuclear energy and research and development for each category an introduction covering important milestones towards its development is followed by the presentation of the relevant policies and a description of their purpose

challenges and countermeasures of china s energy security china is now a major consumer and importer of energy and its choices and policies will increasingly affect the rest of the world this paper analyses the key features of china s energy policy as it faces the prospect of possible challenges to its energy security given the increasing reliance on fuel imports and the need to transform its energy to meet the requirements of a modern fast growing economy the paper examines whether the current energy mix is appropriate and sustainable and considers the china s policymakers new emphasis on energy efficiency conservation renewable energy and the shift to natural gas the primary energy source it examines the internal and external constraints on china s energy policy and considers the strategic dilemmas arising from china s increasing involvement in international energy markets it concludes that both the domestic and international implications of china s search for energy security will confront policymakers with hard choices that will affect not only energy policy but also china s geopolitical grand strategy

evaluating energy security in the asia pacific region a novel methodological approach this paper establishes an energy security assessment instrument based on a new and expanded conceptualisation of energy security the instrument is a systematic interrogative tool for evaluating energy security of individual states or regions it consists of eleven broad energy security dimensions associated with the current global energy system these energy security dimensions take into account numerous quantitative and qualitative attributes of each country s energy security and policy and include both traditional energy security concerns and many new factors such as environmental socio cultural and technological another dimension largely absent from previous analyses is the existence of and the issues addressed in energy security policy in each country this instrument serves as an assessment system with which to evaluate energy security in the asia pacific region the existing studies on energy security in the asia pacific region suffer from serious limitations no study to date examines regional energy security policies by adopting a more comprehensive energy security definition as a starting point most studies also focus on a single country or issue even if they examine energy security in major regional economies they lack critical comparative analysis the instrument is valuable as it may be utilised to draw a comprehensive map of regional energy security situation which can also include comparative analysis of energy security characteristics across the asia pacific region ultimately it may be utilised to set up a framework for improved regional energy cooperation with the aim of providing regional leaders with a blueprint for improving regional energy security and policy

new estimates of the equilibrium exchange rate the case for the chinese renminbi we estimate the nominal equilibrium exchange rate eer of the chinese renminbi rmb vis a vis the us dollar from 1995 to 2009 while most of the recent empirical studies on the eer employ a cross country analysis country specific factors especially supply side real factors are not fully taken into consideration in estimating the eer to better reflect china s processing exports in the context of growing intra regional trade in asia we incorporate in the empirical analysis the source country breakdown data on import prices and input coefficients of intermediate inputs by constructing an annual new international input output iio table for the period from 1995 to 2009 the results show that the nominal eer of the rmb appreciates sharply from 2006 to 2009 suggesting that the current rmb exchange rate has been substantially undervalued and should be revalued by 74 per cent as of 2008 compared to the year 2004 level such sharp appreciation of the nominal eer corresponds to the dramatic increase in china s current account surplus from the mid 2000s especially against the united states which is ascribed to the significant improvement of china s intermediate input coefficients and to a lesser extent an increase in us import prices of intermediate inputs

energy and climate policy in china s twelfth five year plan a paradigm shift the twelfth five year plan fyp endorsed by the people s national congress in march 2011 plays a crucial role in shaping china s development trajectory over the next decades and especially for the fulfillment of the 40 45 carbon intensity reduction target by 2020 the plan will condition both the medium and long term perspectives of economic restructuring rebalance between the inclusive economic growth and environmental objectives which are compounded by multiple constraints faced by china such as aging population natural resources depletion energy supply security and environmental deterioration this article investigates the major energy and climate targets and actions specified in the 12th fyp to gain insights into the nature and magnitude of challenges and difficulties with regard to the medium and long run economic and environmental policies it points out that china should articulate sectoral policies with the global climate mitigation targets to avoid long term carbon lock in based on an in depth analysis of the objectives in the plan it is argued that the implementation should include mainstreaming developments of appropriate instruments to support cost effective energy efficiency improvements and carbon intensity reduction in the next five years

a study of bank efficiency taking into account risk preferences abstract i use the stochastic cost frontier approach to investigate efficiency of banks operating in the third federal reserve district accounting for the quality and riskiness of bank output in addition to the mean and mode of the conditional distribution of the one sided error term i calculate confidence intervals for the inefficiency measures based on the conditional distribution the results indicate that third district banks are operating at cost efficient output levels and product mixes but are not efficiently using their inputs the second part of the article relates the inefficiency measures to several correlates

european union energy policy integration a case of european commission policy entrepreneurship and increasing supranationalism focusing on gas this article explores the role of the european commission in the process of european union energy security policy development and the extent to which the policy area is becoming increasingly supranational situating the article within the literature on agenda setting and framing it is argued that a policy window was opened as a result of enlargement to include more energy import dependent states a trend of increasing energy imports and prices and gas supply disruptions from the mid 2000s the commission contributed to a shift in political norms successfully framing import dependency as a problem requiring an eu level solution based on the institution s pre existing preferences for a diversified energy supply and internal energy market whilst member states retain significant sovereignty the commission has achieved since 2006 creeping competencies in the internal and to a lesser extent external dimensions of eu energy policy

assessing the energy vulnerability case of industrialised countries the emergence of new big consumer countries on the energy markets and the perspective of oil and gas depletion at the end of the current century raise the concerns about fair distribution of the remaining resources for the common and sustainable wellbeing of the mankind high volatility of energy prices discourages the investment and delays the energy technology transition voluntary measures are needed mainly in industrialised countries in order to develop alternative and sustainable energy sources to enable technology transfer towards emerging and developing countries and to avoid struggle for energy procurement in this paper a composite index of energy demand supply weaknesses is defined as a proxy of energy vulnerability the proposed index is based on several indicators such as energy intensity oil and gas import dependency co2 content of primary energy supply electricity supply weaknesses and non diversity in transport fuels the assessment of this composite index for selected industrialised countries is discussed as well as the sensitivity to various factors

scale economies and cost complementarities in commercial banks on and off balance sheet activities abstract bank off balance sheet obs activities have grown dramatically and have become significantly important especially at large banks we investigate whether failure to incorporate obs products may lead to a misspecification problem models that exclude deposits from the output specification suggest economies of scale which vanish when deposits are included we find that inclusion of obs products has little effect on the scale economies measures with only a few exceptions the results provide no evidence of cost complementarities in joint production the tremendous growth of bank obs activities in the 1980s may be explained by the very small approximately zero pecuniary cost of these activities

making room for china in the world economy as it comes out of the crisis the world econ omy faces two apparently conflicting demands on the one hand achieving global macroeco nomic stability and preventing a protectionist backlash will require that we avoid large current account imbalances of the type that the world economy experienced in the run up to the cri sis on the other hand returning to rapid growth in the developing nations will require that they resume their conquest of global market share in tradable goods the challenge of meeting both demands is epitomized by the contentious us china bilat eral relationship american and european policy makers blame china for an undervalued renminbi which they argue is the root cause of china s huge trade surplus chinese leaders resist the pressure fearing that appreciation will undercut the competitiveness of chinese goods in world markets hurt exports and damage growth the western answer to this concern is that china needs to replace foreign demand with domestic demand as the engine of growth but if growth depends primarily on the sup ply of modern manufactured products and other tradables as opposed to services and non trad ables as i will argue here the chinese position has more force than critics give it credit the conventional fix for china s current account surplus consisting of a combination of expendi ture expansion and currency appreciation will shift the structure of the economy away from tradables and towards non tradables this may be good for macroeconomic balance in china and elsewhere but it will almost certainly have adverse effects on china s growth perhaps large enough even to endanger the country s social and political stability

diversity and security in uk electricity generation the influence of low carbon objectives abstract we explore the relationship between low carbon objectives and the strategic security of electricity in the context of the uk electricity system we consider diversity of fuel source mix to represent one dimension of security robustness against interruptions of any one source and apply two different diversity indices to the range of electricity system scenarios produced by the uk government and independent researchers our results show that low carbon objectives are uniformly associated with greater long term diversity in uk electricity generation with reference to data on wind generation we also consider the impact of source variability on a second dimension of security the reliability of generation availability we conclude that this does not undermine our fundamental conclusion that low carbon scenarios are associated with greater strategic security of supply in uk electricity we discuss reasons for this result explore sensitivities and briefly discuss possible policy instruments associated with diversity and their limitations

russian energy in the eu market bolstered institutionsand their effects the article examines institutional changes in eu russian energy relations since 2000 the article explores the ability of transformed institutions to limit the politicisation of energy and to reconcile the eu competitive market approach with russian state capitalism more specifically the article focuses on changes in intergovernmental transgovernmental and transnational interactions the article demonstrates that the gradual strengthening of transgovernmental and transnational institutions has inhibited the politicisation of energy relations and facilitated regulative cooperation between the eu and russia however the potential of shared institutions is constrained by internal institutions on both sides in russia these obstacles are insufficient top down delegation of responsibilities in the government and its great power aspirations in the eu key barriers include inter institutional rivalries the eu s propensity to impose its legislation on external partners and the integration of energy policy with foreign policy the article presents several policy implications first it is futile to institutionally impose the regulative paradigm of one partner on the other rather mutual dialogue is needed thus institutions should be structured appropriately second current depoliticisation will require the involvement of not only the eu and russia but also transit countries such as ukraine third transgovernmental and transnational cooperation should be nurtured because this is a useful channel for both information exchange and a regulative convergence of policy implementing mechanisms finally this incremental regulative convergence is the only option available today for the eu and russia this is also a way to further depoliticise energy relations

chinese investments in europe s energy sector risks and opportunities abstract this paper analyses recent trends in chinese investment in the european energy sector these investments have increased in size targeted a wider number of countries and entered multiple energy sectors in particular fossil renewable energies and energy infrastructure we highlight the significant opportunities for as well as the political and economic risks of chinese investments in the european energy sector on the one hand the benefits can be substantial as china s new role as a global investor offers substantial economic benefits and political partnership further benefits might potentially emerge from backward linkages of chinese investments to improve access to china s restricted markets yet our findings also point to growing concerns among policymakers and business managers in europe ranging from worries about unfair competition and economic risks to concerns about national security we conclude with policy recommendations for the european union and its member states

the determinants of cost efficiency in cooperative financial institutions australian evidence abstract previous studies of efficiency in cooperative financial institutions assume subsidies to be a normal part of business operations using a sample of australian credit unions cus this paper shows that ignoring subsidies biases estimates of cost efficiency and efficiency rankings time varying cost efficiency is estimated using stochastic frontier and generalised within approaches and compared with the distribution free df approach assuming constant efficiency despite significant industry rationalisation average efficiency shows little improvement over the period 1985 1993 however efficiency rankings change considerably second stage regressions suggest bond type size age average deposit size and interest rate spreads are significant determinants of relative cost efficiency

the developing world is poorer than we thought but no less successful in the fight against poverty a new data set on national poverty lines is combined with new price data and almost 700 household surveys to estimate absolute poverty measures for the developing world we find that 25 of the population lived in poverty in 2005 as judged by what poverty typically means in the world s poorest countries this is higher than past estimates substantial overall progress is still indicated the corresponding poverty rate was 52 in 1981 but progress was very uneven across regions the trends over time and regional profile are robust to various changes in methodology though precise counts are more sensitive

resilience and electricity systems a comparative analysis electricity systems have generally evolved based on the natural resources available locally few metrics exist to compare the security of electricity supply of different countries despite the increasing likelihood of potential shocks to the power system like energy price increases and carbon price regulation this paper seeks to calculate a robust measure of national power system resilience by analysing each step in the process of transformation from raw energy to consumed electricity countries with sizeable deposits of mineral resources are used for comparison because of the need for electricity intensive metals processing we find that shifts in electricity intensive industry can be predicted based on countries power system resilience

energy security and sustainability in northeast asia abstract energy security has typically to those involved in making energy policy meant mostly securing access to oil and other fossil fuels with increasingly global diverse energy markets however and increasingly transnational problems resulting from energy transformation and use old energy security rationales are less salient and other issues including climate change and other environmental economic and international considerations are becoming increasingly important as a consequence a more comprehensive operating definition of energy security is needed along with a workable framework for analysis of which future energy paths or scenarios are likely to yield greater energy security in a broader more comprehensive sense work done as a part of the nautilus institute s pacific asia regional energy security pares project developed a broader definition of energy security and described an analytical framework designed to help to compare the energy security characteristics both positive and negative of different quantitative energy paths as developed using software tools such as the leap long range energy alternatives planning system

chinese investment in the eu renewable energy sector motives synergies and policy implications abstract this paper addresses three questions how have trade and investment in wind and solar sectors evolved between the eu and china in recent years is there a link between rising trade conflicts and trade and investment trends and what wider motivations and synergies can be identified in chinese investments in the eu s re sector to address these questions we analyze trade and investment data as well as qualitative data including information from media and company reports large increases in trade and investment were followed by rapid falls since 2012 13 trade tensions have not led to increases in investment rather the inverse we find that chinese investment in these two sectors is very concentrated in germany the key motivation for investment is market seeking although r d is also important especially for wind most investments are greenfield a preference that has persisted over time our qualitative analysis of several key acquisitions indicates that technology integration and the consolidation of capacities across the supply chain were key motivations in most of the cases studied we conclude with some policy orientations

a quantitative analysis of low carbon society lcs measures in thai industrial sector abstract energy is a commodity which impacts heavily upon the competitiveness of a country in the global scale thus nations have begun to understand that utilization of energy affects its economic performance in recent times there has been a drive for global awareness on low carbon society lcs measures where carbon mitigation is at the forefront thus this paper analyses the lcs measures for the thai industrial sector thai industrial sector is the second highest co 2 emitting end use sector and contributes approximately 30 to the national income of thailand the total co 2 emission from end use sectors in 2010 was 119 mton co 2 and approximately 38 constituted industrial sector emissions the primary objective of this research study is to quantitatively analyse the carbon mitigation possible in the thai industrial sector and the co benefits which accrue along with mitigation in various policy pathway scenarios thai industrial sector was modeled using asia pacific integrated model aim enduse three groups of scenarios under lcs emission tax and reduction target principles were modeled along with the bau case results show that lcs scenarios are capable of cumulative mitigation of approximately 35 by 2050 in comparison to the bau case and the predominant technologies are the 2nd generation biomass and the ccs technology the emission tax scenarios where tax rates of 50 100 200 and 500 usd t co 2 were enforced show a maximum of 55 cumulative mitigation by 2050 even though this reduction is higher than the lcs scenarios there is no shift to long term renewable or sustainable technologies in the emission tax scenarios the same applies to reduction target scenarios as well the co benefits which were measured along the themes of energy security and local air pollutant mitigation show maximum benefits accruing to the lcs scenarios where renewable fuel share increases whilst primary energy intensity and carbon intensity decreases the lcs scenarios also show a mitigation of local air pollutants such as so 2 and particulate matter

low carbon society scenario analysis of transport sector of an emerging economy the aim enduse modelling approach abstract the transport sector of a country is the backbone driving the economy forward thailand s land transport sector is modelled using the aim enduse which is a recursive dynamic optimization model based on bottom up modelling principle the travel demand is divided into two major categories which are passenger travel and freight travel the objective of this paper is to analyse the mitigation possible through low carbon society lcs measures and emission tax et two scenario clusters are devised along with the bau case the lcs scenario cluster has three designed scenarios which are lcs l lcs m and lcs h the emission tax et cluster has four scenarios where the taxes of 50 100 200 and 500 usd t co2 are implemented along with this the marginal abatement costs mac of the counter measures cms and the co benefits in terms of energy security productivity and air pollutant mitigation are also assessed results show that lcs scenarios are possible of mitigating up to 1230 mt co2 cumulatively from 2010 to 2050 in terms of macs new vehicles play a pivotal role along with hybrid vehicles the average abatement cost aac assessment shows that the aac of lcs h scenario is in the order of 100 usd t co2 all the lcs and et scenarios show an enhancement in energy security and also a threefold increase in productivity there is distinct mitigation in terms of air pollutants from the transport sector as well

managers and efficiency in banking abstract this paper presents evidence on the impact of managers on cost efficiency in banking stochastic frontier analysis is applied to a unique finnish data set manager age and education have strong yet complicated effects on efficiency the impact of age on efficiency depends on education a university degree is useful mainly in the largest banks of the sample educational background seems to be less important for young managers than for mature ones managing director changes are systematically followed by efficiency changes retirement typically causes an efficiency improvement whereas other manager changes can either improve or weaken efficiency however in many cases mature managers outperform their young colleagues

indicators of energy security in industrialised countries energy security has become a popular catch phrase both in the scientific arena as well as in the political discussion yet in general the applied concepts of energy security are rather vague this paper sheds some light on concepts and indicators of energy security first we conceptually discuss the issue of energy supply security and explain why it is not to handle by one science alone and what economics may contribute in order to structure the topic after providing a brief survey of existing attempts to define or measure energy security we suggest an additional dimension along which indicators of energy security may be classified ex post and ex ante indicators finally we illustrate our concept on the basis of several simplified indicators while ex post indicators are mostly based on price developments ex ante indicators are to a greater extent aimed at illustrating potential problems our illustration suggests that it is worthwhile to take into account the market structure along with the political stability of exporting countries

on the sources of heterogeneity in banking efficiency literature one learns two main lessons from studying the great quantity of banking efficiency literature these lessons regard the heterogeneity in results and the absence of a comprehensive review aimed at understanding the reasons for this variability surprisingly although this issue is well known it has not been systematically analyzed before in order to fill this gap we perform a meta regression analysis mra by examining 1 661 efficiency scores retrieved from 120 papers published over the period 2000 2014 the meta regression is estimated by using the random effects multilevel model reml because it controls for within study and between study heterogeneity the analysis yields four main results firstly parametric methods yield lower levels of banking efficiency than nonparametric studies this holds true even after controlling for the approach used in selecting the inputs and outputs of the frontier secondly we show that banking efficiency is highest when using the value added approach followed by estimates from studies based on the intermediation method whereas those based on the hybrid approach are the lowest thirdly efficiency scores also depend on the quality of studies and on the number of observations and variables used in the primary papers as far as the effects of sample size dimension and quality of papers are concerned there are significant differences in sign and magnitude between parametric and nonparametric studies finally cost efficiency is found to be higher than profit and production efficiency interestingly mra results are robust to the potential outliers in efficiency and sample size distributions

the methodological challenges of creating a comprehensive energy security index this short article defends the methods utilized in creating an energy security index it explains why an energy security index is needed and then justifies research interviews as a data collection tool next it responds to the three strands of professor cherp s critique before offering a few general conclusions for readers concerned about energy security

differing cultures of energy security an international comparison of public perceptions this study reviews how energy users perceive the importance of energy security dimensions it asks how does the sense of energy security vary with culture its primary source of data is a summary of survey distributed in eight languages to almost 2500 respondents in brazil china denmark germany india kazakhstan japan papua new guinea saudi arabia singapore and the united states it utilizes an energy literacy test in denmark as a secondary data tool the survey results are used to test nine hypotheses about national economic political professional and epistemic cultures the study concludes by affirming the complexity of energy security as a cultural topic by emphasizing how answers among respondents tended to converge more than diverge and by calling for further research

evaluating energy security of resource poor economies a modified principle component analysis approach abstract this study proposes to aggregately measure energy security performance with the principal component analysis in its application of the methodology to four resource poor yet economically advanced island economies in east asia singapore south korea japan and taiwan this study establishes a novel framework to conceptualize energy security the framework incorporates three dimensions vulnerability efficiency and sustainability three indicators being allocated to each dimension the study finds that all the three dimensions are critical for the resource poor economies but have different weights in each of them an urgent task for these four economies is to implement energy efficiency and conservation measures liberalization of electricity sector can be a helpful tool to reduce energy consumption and increase efficiency all of them have been committed to promoting renewable energy development which shall be further expanded in these economies

polices for increasing energy efficiency thirty years of experience in oecd countries energy efficiency improvement was an important phenomenon in the global energy balance over the past 30 years without energy efficiency improvements the oecd nations would have used approximately 49 more energy than was actually consumed as of 1998 this paper first reviews energy intensity trends for the major oecd nations since 1973 considering how much of the overall reduction in e gdp was due to energy efficiency improvement and how much was due to structural change the bulk of the paper examines the energy efficiency policies and programs adopted in japan united states and western europe commenting on their effectiveness and energy savings impacts where possible the paper also reviews the energy efficiency policies and programs adopted in california this experience shows that well designed policies can result in substantial energy savings as demonstrated in the united states where nine specific policies and programs reduced primary energy use in 2002 by approximately 11 substantial energy savings also occurred in japan some european countries and in the electricity sector in california

balancing energy security priorities portfolio optimization approach to oil imports the notion of energy security in most interpretations includes the physical supply and price affordability components making financial risks a crucial part of energy security strategies mainstrea

how to promote the growth of new energy industry at different stages abstract china is currently the world s largest emitter of carbon dioxide co2 vigorously developing new energy sources has become an important way to reduce co2 emissions therefore more and more scholars have studied effective ways to promote the development of new energy industry however most of the existing research use single equation linear models or static models to study the driving forces of the new energy industry this not only ignores the large number of dynamic relationships between economic variables but also produces endogeneity problems in order to overcome the shortcomings of existing research this paper uses vector autoregressive model to study the new energy industry the results show that energy consumption structure has a positive effect on the new energy industry in the short run but the effect is limited in the long run the impact of the agriculture industry is gradually narrowing over time due to the gradual reduction of crop acreage however the influence of economic growth is positive both in the short and long run this is due to the gradual optimization of industrial structure technological progress produces a similar impact owing to continued investment in research and development funding as well as research and development personnel

is energy security a driver for economic growth evidence from a global sample abstract this study examines whether energy security contributes to economic growth for a global sample of 74 countries covering the period from 2002 to 2013 the benchmark model is built based on an extended version of the cobb douglas production function ten measures of energy security are employed to capture five aspects of energy security including availability accessibility acceptability affordability and develop ability besides the whole sample we also conduct the panel data analysis on subsamples of countries based on different income levels using panel corrected standard errors pcse and feasible generalized least squares fgls techniques that correct for heterogeneity and autocorrelation and produce robust standard errors the empirical results appear to be relatively robust to these two estimation techniques overall we find that energy security enhances economic growth for both the whole sample and subsamples of countries meanwhile energy insecurity measured by energy intensity and carbon intensity variables has a negative impact on economic growth the results vary across subsamples for several cases the findings imply that at the global level energy for economic development energy security and climate change mitigation should be pursued as integrated themes since there are linkages among these three agendas

the impact of opec on east asian oil import security a multidimensional analysis abstract east asian countries such as china japan and south korea are major importers in the international oil market therefore oil import security is critical to sustainable economic development in these countries this paper uses a modified two stage dea like model to investigate the impact of the organization of petroleum exporting countries opec on oil import security in the east asian region over time specifically three dimensional variables were introduced to the model the opec internal dimension the opec and asian country interaction dimension and the international external dimension the empirical results show a substantial difference between china and the other two countries in terms of these dimensions although the impact of opec on china s oil security has increased over time its impact on japan has declined political uncertainty in opec countries and oil price volatility are the major issues for china whereas cost is the key area of concern for japan south korea s concerns are less clear the results of this study lay an important foundation for discussing policy issues involved in regional cooperation integration and sustainable growth in the east asian region

efficiency in the savings and loan industry abstract the stochastic econometric cost frontier approach is modified to investigate efficiency in mutual and stock s ls using 1991 data on u s s ls this methodology allows both the cost frontier and error structures to differ between s ls of these two ownership forms a likelihood ratio test indicates that the data support this unrestricted model which implies efficient mutual and stock s ls use different production technologies various measures of inefficiency show that on average stock s ls are less efficient than mutual s ls the second part of the article relates the inefficiency measures to several correlates

long term energy services security what is it and how can it be measured and valued abstract the paper reviews some recent approaches towards measuring the extent of long term energy security and security externality valuation it starts out to discuss the contextual connotations of notions of energy security in medium to long term time frames and reviews some indicators that have been proposed to quantify it special attention is paid to two of these approaches which the authors helped to develop i e diversity based indices and the supply demand index the paper takes issue with conventional welfare economic approaches that neglect i the scope on the demand side for raising security and ii negative feedback mechanisms of socio political impacts of international rent transfers in fossil fuels exporting countries the concept of energy services security is proposed with a demand side focus this enables application of an integrated approach to gauge the resilience of a society to meet the needs of its population for energy services over longer timescales ahead from various interrelated perspectives propositions are made on the attribution of security externalities to the use of fossil fuels policies and suggestions for further improvements of measures for energy services security

efficiency and technical progress in banking empirical results for a panel of german cooperative banks abstract using 1989 1992 individual data of 757 german cooperative banks and applying the intermediation approach we specify a multi product translog cost function for this part of the german banking industry for all size classes moderate economies of scale can be identified there is also evidence of economies of scope which supports the notion of universal banking as for cost efficiency we find that the average banks in all size classes deviate considerably from the best practice cost frontier all banks enjoy growth of total factor productivity which is higher for the smaller banks in the sample

an international assessment of energy security performance energy security has in recent years grown as a salient policy and political issue to better understand energy security and sustainability concerns this study s main objective is to present an energy security index which measures national performance on energy security over time based on three years of research involving interviews surveys and an international workshop this study conceptualizes energy security as consisting of the interconnected factors of availability affordability efficiency sustainability and governance it then matches these factors with 20 metrics comprising an energy security index measuring international performance across 18 countries from 1990 to 2010 it offers three case studies of japan top performer laos middle performer and myanmar w orst performer to provide context to the index s results it then presents four conclusions first a majority of countries analyzed have regressed in terms of their energy security second despite the near total deterioration of energy security a great disparity exists between countries with some clear leaders such as japan third tradeoffs exist within different components of energy security fourth creating energy security is as much a matter of domestic policy from within as it is from foreign policy without

indicators for energy security the concept of energy security is widely used yet there is no consensus on its precise interpretation in this research we have provided an overview of available indicators for long term security of supply sos we distinguished four dimensions of energy security that relate to the availability accessibility affordability and acceptability of energy and classified indicators for energy security according to this taxonomy there is no one ideal indicator as the notion of energy security is highly context dependent rather applying multiple indicators leads to a broader understanding incorporating these indicators in model based scenario analysis showed accelerated depletion of currently known fossil resources due to increasing global demand coupled with increasing spatial discrepancy between consumption and production international trade in energy carriers is projected to have increased by 142 in 2050 compared to 2008 oil production is projected to become increasingly concentrated in a few countries up to 2030 after which production from other regions diversifies the market under stringent climate policies this diversification may not occur due to reduced demand for oil possible benefits of climate policy include increased fuel diversity and slower depletion of fossil resources

diversification of oil import sources and energy security a key strategy or an elusive objective this paper explores the relationship between the diversification of sources of imported oil and energy security of oil importing countries it examines the importance of diversification policy for oil importers explains why oil importers implement oil diversification policy and contextualizes the oil import diversification strategy in the overall energy security policy of oil importers the paper analyzes the factors and the contexts that affect the level of importance assigned to oil import diversification policy in oil importing countries and the limitations that may affect the successful implication of oil import diversification policy the examples are drawn from the world s top three oil importers the united states japan and china the policymakers in these and other oil importing countries place much importance on energy security the diversification of oil import sources is used as one of the strategies to enhance energy security in oil importing countries this paper is important for policymakers in oil importing countries as it provides them with a qualitative conceptual framework with which to evaluate the need to diversify their countries sources of imported oil and with which to identify the likely limitations to the successful implementation of oil import diversification policy

china s sovereign wealth fund investments in overseas energy the energy security perspective abstract sovereign wealth funds swfs are state owned investment funds that invest in real and financial assets since the global financial crisis in 2008 swfs investments have resulted in national security concerns of host countries because swfs continue to expand rapidly and have become increasingly active in real time strategic transactions given this background china which has the biggest swf in the world is facing severe challenges of energy resources shortages while its plan is to accomplish social and economic development goals energy security is a key driving force of the energy investment policy of china s swfs this makes the swf investments more complicated and more politically sensitive the combination of sovereign rights and the strategic importance of energy also makes geopolitics more complicated and brings more uncertainty to swf investments this article explores the relationship between energy security and energy investments of china s swfs it is recognised that the energy investment of swfs must follow a sustainable path to coordinate energy security economic growth return on investment and national security concerns government policymakers are urged to balance the financial and political returns on swfs against potential negative effects the conclusion presents insights for policymakers energy scholars and swf researchers

will the european commission s policy hinder gas supplies to central and eastern european countries opal case decision abstract natural gas has become one of the most important sources of energy the liberalization of the gas sector in the last decades brought a dynamic development of the energy infrastructure in the eu thus it must be underlined that the liquidity of the gas market is dependent on the outside supplies the study examines the european commission s policy taking into consideration specifically its decision on the exemption of opal gas pipeline from eu rules the main question is what would be the long term effect of such policy in the authors opinion there are several serious doubts whether the commission has made an appropriate decision the major one concentrate on the impact of the decision which according to the commission refers only to germany and czechia gas market nevertheless an analysis of gas flow based on the entsog leads to a conclusions that decision could have a substantial influence on slovakia and poland if so under the eu provisions the investment can not be excluded form the eu rules therefore the authors will analyze step by step the commission decision and present its possible future impact on the internal energy market

macroeconomic and political aspects of energy security exploratory data analysis abstract although the issue of energy security stands high on the scale of the european union s priorities there has been no single accepted definition of energy security thus far in light of the global economic crisis and political instability the issue of energy security is directly linked to geopolitical and macroeconomic stability this paper offers a new method of measuring energy security which unlike the existing indicators of energy stability in addition to economic and environmental indicators also includes the political and social aspects within the composite indicator of country risk the new energy security index esi is defined based on the application of principal component analysis pca analysis of the values of a new esi indicator shows that energy security is greatly influenced by gdp per capita country risk carbon intensity energy intensity final energy consumption per capita and electricity prices while the least importance rests with the share of renewable sources in energy consumption and energy dependence the values of the index by country are stable over the entire observed period but significant differences are noticeable between countries the highest index values are reported in luxembourg sweden finland and denmark and the lowest in bulgaria romania estonia and poland with the aim of robustness check the results of eu member states rankings were compared to country rankings based on the energy trilemma index compared to country rankings based on the energy trilemma index three countries recorded the same rank denmark check republic and bulgaria and the biggest deviation of 9 ranking position was reported by luxembourg the results of the research show that there is a statistically important difference in the value of energy security index between the observed groups of countries classified according to the level of macroeconomic stability

environmental support energy security and economic growth in japan this study investigates the resource consumption of japanese society since 1979 and its subsequent effects on the economic output of the nation and the environment in order to quantify resource appropriation and trends in production and consumption the concept of emergy synthesis is employed our results show a significant increase in the total amount of emergy consumed by 66 9 between 1979 and 2003 which comes hand in hand with an increase in the level of environmental stress by 93 7 quantified as the environmental loading ratio on the other hand the emergy required to produce 1 usd of economic output has been gradually decreasing which denotes an increase in the efficiency of the conversion of natural capital into economic output what is most interesting though is the growing dependence of the japanese economy on imported emergy increasingly from developing nations that severely affects the potential for unhindered economic growth this can prove to be a big barrier that could affect the resource security of the japanese economy and render it susceptible to risks associated with access to natural resources which in turn can jeopardise its long term economic sustainability

energy policymaking in denmark implications for global energy security and sustainability denmark is arguably the most energy secure and sustainable country in the organization of economic cooperation and development oecd the country has reduced its dependence on foreign sources of energy to zero and become self sufficient in its own energy production and use offering important lessons for other nations around the world this study explores the core of denmark s successful approach a commitment to energy efficiency prolonged taxes on energy fuels electricity and carbon dioxide and incentives for combined heat and power chp and wind turbines through these commitments the study shows how denmark transitioned from being almost 100 percent dependent on imported fuels such as oil and coal for their power plants in 1970 to becoming a net exporter of fuels and electricity today the country leads the world in terms of exportation of wind energy technology with a hold on roughly one third of the world market for wind turbines it was able to phase out the use of virtually all oil fired power plants in less than five years and implemented a progressive moratorium on future coal fired power plants in the 1990s their most recent strategy seeks to achieve 30 percent of total energy supply from renewable energy by 2025

assessment of energy security in china based on ecological network analysis a perspective from the security of crude oil supply abstract energy security usually considers both the stability of energy supply and security of energy use and it is receiving increasing attention globally considering the strategic importance and sensitivity to international change of the crude oil supply we decided to examine china s energy security an original network model was established based on ecological network analysis to holistically evaluate the security of the crude oil supply in china using this model we found that the security of the crude oil supply in china generally increased from 2001 to 2010 the contribution of different compartments in the network to the overall energy security resembled a pyramid structure with supply sources at the bottom the consumption sector at the top and the refining and transfer sectors in the middle north and south america made the largest contribution to the security of the crude oil supply in china we provide suggestions to improve the security of the crude oil supply in china based on our results and further scenario analysis the original network model provides a new perspective for energy security assessment which can be used as a baseline to develop other models and policy

the japanese energy sector current situation and future paths abstract as the world s third leading economy and a major importer of fuels the choice of future energy paths and policies that japan makes in the next few years will have a significant influence on the energy security of the world as a whole and of the northeast asia region in particular in this article we describe the current status of and recent trends in the japanese energy sector including energy demand and supply by fuel and by sector we then discuss the current energy policy situation in japan focusing on policies related to climate change targets renewable energy development and deployment liberalization of energy markets and the evolution of the japanese nuclear power sector the final section of the article presents the structure of the japan leap long range energy alternatives planning software system dataset describes several alternative energy paths for japan with an emphasis on alternative paths for nuclear power development and ghg emission abatement and touches upon key current issues of energy policy facing japan as reflected in the modeling inputs and results

shifting policy priorities in eu china energy relations implications for chinese energy investments in europe shifting energy policy priorities both in china and the eu european union have transformed their bilateral relationship in order to assess the impact of domestic policy priorities on bilateral energy cooperation and climate policy this comparative study traces the evolution of eu and chinese approaches to energy policy and their relative emphasis on factors and frames such as availability efficiency affordability and environmental stewardship drawing on government documents and a data set of interviews with chinese policy makers experts and academics in 2015 2016 the article argues that while the eu started with a strong emphasis on environmental stewardship and moved towards a focus on affordability and availability china started with a strong emphasis on availability and has moved towards a greater emphasis on environmental stewardship this shift in frames on the chinese side and subsequent changes in subsidy structures and targets can partially explain the increase in investments in renewable energy technologies the article concludes that the chinese and eu perspectives have become more aligned over the past ten years coinciding with an increasing trend towards renewable energy in chinese energy investments in the eu for example in italy and the uk

between russia as producer and ukraine as a transit country eu dilemma of interdependence and energy security abstract between 2014 and 2015 the eu started a new energy policy in order to address among other issues the problematic character of energy interdependence with russia and thus improve its energy security the aim of this article is to determine how this policy considered interdependence with russia in the light of diversification alternatives energy security is seen through short term and long term dimensions which can be equated to the concepts of vulnerability and sensitivity interdependence as the article shows the alternative of lng is limited by production and consumption patterns in both europe and other world markets it also shows that maintaining interdependence with russia and reducing the role of transit countries such as ukraine would yield benefits both in vulnerability and sensitivity interdependence however while the eu has strongly based its rhetoric on the promise of lng it has ignored alternatives that would maintain interdependence with russia eventually the eu s energy strategy has acknowledged the limitations of lng even though it has not changed its stance towards russia in that respect it seems fair to conclude the eu has not rigorously analysed the transit dimension in its interdependence with russia and the implications for its energy security

evaluating the performance of us credit unions credit unions are small cooperative not for profit institutions which distinguishes them from other financial intermediaries in this study we conduct a performance evaluation of credit unions the criteria respect the unique organizational and institutional features of credit unions without losing sight of the fact that they must compete with other financial intermediaries we use nonparametric nonstochastic techniques to measure performance and we use parametric stochastic techniques to attribute performance variation to features of credit unions and their operating environment our sample consists of two thirds of all active credit unions in 1990
