the empirical analysis of the determinants for environmental technological change a research agenda abstract technological change is usually considered a necessary albeit not sufficient condition for a transition to sustainability however the empirical analysis of the determinants to environmental technological change has not received too much attention in the environmental ecological economics literature and many open questions remain in this context based on a careful review of the literature this paper argues that further analysis should address several issues at different levels i e regarding the conceptual framework the thematic scope of the studies some methodological issues and other aspects related to the environmental policy variable first an integrated conceptual framework which takes into account the interplay between relevant variables influencing environmental technological change i e factors internal and external to the firm and characteristics of the environmental technologies and all the stages of this process with a greater emphasis on the invention stage should be developed other aspects should then be tackled including a focus on several themes i e a greater attention to cross sectoral technologies the barriers to different types of environmental technologies the international dimension of environmental technological change and environmental technological change in small and medium size enterprises methodological issues combination of case studies and econometric modelling and several issues related to the environmental policy variable

a comparative study of efficiency in european banking this paper investigates whether there has been an improvement in and convergence of productive efficiency across european banking markets since the creation of the single internal market using efficiency measures derived from dea estimation the determinants of european bank efficiency are evaluated using the tobit regression model approach the established literature on modelling the determinants of bank efficiency is then extended by recognizing the problem of the inherent dependency of dea efficiency scores when used in regression analysis to overcome the dependency problem a bootstrapping technique is applied overall the results suggest that since the eu s single market programme there has been a small improvement in bank efficiency levels although there is little evidence to suggest that these have converged the results also suggest that inference on the determinants of bank efficiency drawn from non bootstrapped regression analysis may be biased and misleading

interactions of factors impacting implementation and sustainability of renewable energy sourced electricity abstract two renewable energy sourced electricity res e technologies are at the forefront of the current energy transition away from fossil fuels wind and solar photovoltaic however res e must overcome implementation and sustainability challenges from factors identified in economic policy societal technological and environmental dimensions res e diffusion is also a complex problem and this critical review suggests that outcomes depend on interdependencies between factors within a single or across multiple dimensions four categories of interactivity have been identified higher capital costs or market inequalities associated with the economic dimension of res e drive supportive policies or incentives in the policy dimension in the policy policy category interactions between res e demand or supply side incentives influence electricity pricing energy market mixes or greenhouse gases emissions the society technology category examines societal technological interactions at both micro and macro scales the environment technology category details interactions between res e and the environment the technology technology category examines synergies between res e when collocated with conventional electricity generation technologies this review identified several knowledge gaps first research on res e implementation lacks system level analyses on the impact of interactions on project outcomes a well developed line of research examines interactions between multiple simultaneous supportive policies on res e implementation in developed nations however a second gap exists on the understanding of these interactions in developing nations a third gap exists on evaluating the impact of technological lock in this includes the impact on res e implementation rates when the complex economic policy governance and societal factors implicated in lock in are removed

why haven t developing countries privatized deeper and faster abstract despite a decade of privatization in the developing world the vast majority of state owned enterprise soe assets continue to be in government hands bureaucrats in business world bank 1995 correctly identifies politics as one reason for the slow pace of privatization but it underestimates the role of institutional and economic constraints success stories of privitization are rare in low income countries and the long term promise of privatization in sectors posing regulatory complications remains to be established countries in crisis may reform soes quickly and deeply despite these uncertainties but others may opt for gradual reform which need not be altogether bad if speedy privatization results in poorly conceived schemes the cure can be worse than the illness finally bureaucrats are likely to stay in business for years to come and therefore it is important to improve their effectiveness in the roles they are unlikely to shed in the future a market friendly approach to soe reform need not be government un friendly

the innovation impact of the eu emission trading system findings of company case studies in the german power sector abstract this paper provides a detailed analysis of how the european emission trading system eu ets as the core climate policy instrument of the european union has impacted innovation towards this end we investigate the impact of the eu ets on research development and demonstration rd d adoption and organizational change in doing so we pay particular attention to the relative influences of context factors policy mix market factors and public acceptance and firm characteristics value chain position technology portfolio size and vision empirically our qualitative analysis is based on multiple case studies with 19 power generators technology providers and project developers in the german power sector which were conducted in 2008 09 we find that the innovation impact of the eu ets has remained limited so far because of the scheme s initial lack of stringency and predictability and the relatively greater importance of context factors additionally the impact varies significantly across technologies firms and innovation dimensions and is most pronounced for rd d on carbon capture technologies and organizational changes our analysis suggests that the eu ets on its own may not provide sufficient incentives for fundamental changes in corporate innovation activities at a level which ensures political long term targets can be achieved

recent developments of solar energy in india perspectives strategies and future goals abstract power is the most paramount ingredient of infrastructure for growth in economics and welfare of a nation development for sustaining the growth of the indian economy in the existing infrastructure is crucial the power sector of india is one of the largest expanded power sectors in the world due to the continuous increment in electricity demand day by day indian power sector is interfacing some challenges to maintain the balance between the power generation and demand with suffering from supply constraints and shortages in power for maintaining the ratio of generation and demand of power moving from conventional sources to non conventional sources is not only an option it is a necessity the importance of using solar as an energy source in india s perspectives in not only to increase power generation but also to expand energy reliability with considering the environmental social independent and financial beneficial properties this paper analyzes the recent scenario strategies availability future potential policies and development of solar energy in emerging indian power sector

a stochastic dea study of hotel efficiency this current study is the first to apply stochastic data envelopment analysis sdea approach to assess the efficiency of hotels the determinants of hotel efficiency were also investigated employing the tobit regression model approach the sdea results show that the sdea efficiency measures are higher than the deterministic ones and the greater the stochastic variability of outputs the closer the envelope moves successively to any given observation and the efficiency score approaches one the optimal solution to sdea involves the presence of some buffer slack of all outputs in applications involving practice production situation such buffer slack can be interpreted as the firms need to hold inventory excess capacity and organizational slack against stochastic uncertainty of market environment our results also indicate that resort hotels achieve better efficiency than those in metropolitan areas and operating as part of a chain is not the main determinant of the efficiency of international touri

back to the future rethinking auctions for renewable electricity support abstract the effectiveness and cost effectiveness of two main types of instruments feed in tariffs and quotas with tradable green certificates have usually been compared in the literature on renewable electricity promotion due to negative past experiences with a third instrument auctions this instrument has been broadly dismissed in academics and until recently also in policy practice however and based on an in depth review of experiences with auction schemes for renewable electricity around the world this paper argues that some of the problems with auctions in the past can be mitigated with the appropriate design elements and that indeed auctions can play an important role in the future implementation of renewable electricity support instruments around the world the paper provides a proposal for the coherent integration of several design elements

the induced innovation hypothesis and energy saving technological change we develop a methodology for testing hicks s induced innovation hypothesis by estimating a product characteristics model of energy using consumer durables augmenting the hypothesis to allow for the ine uence of government regulations for the products we explored the evidence suggests that i the rate of overall innovation was independent of energy prices and regulations ii the direction of innovation was responsive to energy price changes for some products but not for others iii energy price changes induced changes in the subset of technically feasible models that were offered for sale iv this responsiveness increased substantially during the period after energy efficiency product labeling was required and v nonetheless a sizable portion of efficiency improvements were autonomous

explaining the attacker s advantage technological paradigms organizational dynamics and the value network abstract understanding when entrants might have an advantage over an industry s incumbent firms in developing and adopting new technologies is a question which several scholars have explained in terms of technological capabilities or organizational dynamics this paper proposes that the value network the context within which a firm competes and solves customers problems is an important factor affecting whether incumbent or entrant firms will most successfully innovate in a study of technology development in the disk drive industry the authors found that incumbents led the industry in developing and adopting new technologies of every sort identified by earlier scholars at component and architectural levels competency enhancing and competency destroying incremental and radical as long as the technology addressed customers needs within the value network in which the incumbents competed entrants led in developing and adopting technologies which addressed user needs in different emerging value networks it is in these innovations which disrupted established trajectories of technological progress in established markets that attackers proved to have an advantage the rate of improvement in product performance which technologists provide may exceed the rate of improvement demanded in established markets this mismatch between trajectories enables firms entering emerging value networks subsequently to attack the industry s established markets as well

power sector reform in india current issues and prospects power sector reforms in india were initiated at a juncture when the sector was plagued with commercial losses and burgeoning subsidy burden investment in the sector was not able to keep pace with growing demand for electricity this paper takes stock of pre reform situation in indian power sector and identifies key concerns that led to initiation of the process of reform the paper discusses major policy and regulatory changes undertaken since the early 1990s the paper also illustrates changes in the market structure as we move along the reform process we also discuss some of the major provisions of the recently enacted electricity act 2003 that aims to replace the prevailing acts which govern the functioning of the power sector in the country in this context we discuss two issues arising out of it namely open access and multi year tariff that we think would have a significant bearing on the performance of the sector in the near future the paper also evaluates the reform process in the light of some of the regulatory changes undertaken finally the paper briefly discusses the issues involved in introduction of competition in the power sector primarily through development of a market for bulk power

bias and precision in the dea two stage method in data envelopment analysis dea the two stage method is a popular procedure for accounting for exogenous influences on efficiency with the conventional two stage method a dea is first conducted using only traditional endogenous inputs and outputs then the first stage dea scores are regressed on the environmental contextual exogenous inputs of interest the regression outcomes are used to identify exogenous inputs that influence the first stage dea scores to a statistically significant degree and to adjust dea scores to account for these influences herein it is demonstrated empirically that the conventional method exhibits substantial bias and low precision with the degree of bias and precision affected by input variance and correlation a reverse two stage procedure that yields estimates without the bias and precision problems that compromise the validity of the conventional method s estimates is suggested

the role of policy instruments in the innovation and diffusion of environmentally friendlier technologies popular claims versus case study experiences abstract moving towards sustainability will require that new environmentally friendlier technologies are developed and widely adopted policy instruments that promote eco efficiency are therefore necessary some claims frequently made in the literature on the relationship between policy instruments and technological development are examined the claims concern regulations environmental taxation and funding of research and development the claims are explored on the basis of empirical evidence from two sectors the pulp and paper industry and the marine engine industry little support was found for some of the claims in some cases even contradictory findings and for some claims the findings differed between the sectors and even within a sector depending on the issue

benchmarking superannuation funds based on relative performance in this article we assess fund performance using data envelopment analysis dea for each inefficient fund dea provides a set of role model funds whose best practices may be emulated for performance improvement we find that the role models of most inefficient funds consist entirely of funds different from their own type to overcome this situation we suggest a multi step dea procedure the procedure starts by categorizing funds on a hierarchical basis we establish the hierarchy based on the frequency of efficient funds that belong to each fund type thereafter a set of role model funds for each inefficient fund is found by pooling the funds in its own category and the funds that belongs to the categories at the lower levels in the hierarchy and applying dea this procedure is repeated by augmenting the pool with funds at the next higher level and so on until all the sampled funds are included at each step a set of role models is identified an inefficient fund can thus reach the efficient frontie

efficiency and risk in taiwan banking sbm super dea estimation in this study we adopt the two data envelopment analysis dea methods including banker charnes cooper bcc and slacks based measure sbm super efficiency to investigate whether a bank s technical efficiency index s results incorporating account risk and not incorporating account risk differ significantly the information is obtained from 43 taiwanese banks for the period 1998 to 2002 we also employ the nonradial and slacks based malmquist total factor productivity tfp index to measure the impact of productivity change on the panel data our empirical results from the dea approach are summarized as follows 1 loan quality factors have an impact on a bank s efficiency in general the bank with a higher degree of problem loans drops down its efficiency by incorporating account risk however the bank with a lower degree of problem loans increases its efficiency by incorporating account risk 2 super efficiency provides a good framework for ranking efficient units 3 based on the nonradial an

technical and allocative efficiency in european banking this paper specifies an empirical framework for estimating both technical and allocative efficiency using the translog cost share system thus providing a solution to the issue known in the literature as the greene problem the model is applied to a large panel of european banks and the results are compared with those of a model that does not include an allocative inefficiency term and also with those obtained by using a consistent bayesian technique our results suggest that models which include only technical efficiency significantly overestimate it while parameter estimates from the model that includes both technical and allocative efficiency are very close to the ones obtained from the bayesian approach thus enhancing our confidence in the proposed methodology finally the fact that allocative efficiency of banks in our sample improves more than technical efficiency underlines the importance of including an allocative inefficiency component in parametric efficiency models

broken dreams unmet expectations of investors in the philippine electricity restructuring and privatization abstract over the last three decades privatization and restructuring of electricity sectors has been a hot topic the expectation was that prices would fall due to increased competition and that generators would become more innovative and efficient however the enthusiasm for deregulation wavered after events such as the debacle in california the fall of enron and the setbacks of ontario in the philippines comprehensive legislation was passed in 2001 but the implementation has been rather slow and controversial this paper looked at the allegation of politicizing power rates and found a logical alternative to the perceived conspiracy angle based on market data it is highly probable that depressed market rates was a result of coping mechanisms of new players trying to adjust to the restructured industry

electricity auctions in south america towards convergence of system adequacy and res e support regulatory reforms of the electricity industry in south america have always been prompted by the need of attracting enough investment to cover the fast paced demand growth in order to achieve this goal the countries in the region which in the eighties and early nineties opted for market oriented schemes have rebuilt in the last decade their regulatory frameworks around long term auctioning these new mechanisms initially implemented to attract investment in any sort of conventional generation technology so as to ensure the system adequacy are increasingly being also used to bring in non conventional renewable energy resources these schemes have been until now run in parallel but the steep learning curve of renewable energy sources for electricity res e technologies is apparently opening the door to the implementation of new tendering procedures open to all kinds of generation technologies in this article we review the auction mechanisms for new generation implemented in south america we argue that although the first impression might lead to the conclusion that conventional and res e technologies are in some cases close and even ostensibly competing in the same auctions the fact is that the full convergence is still far to happen as the rules and products applied to the different technologies differ significantly

bank s risk taking and ownership structure evidence for economics in transition stage conventional studies assume that inside management plays a major role in corporate governance and argue that foreign institutional investors may lack incentives to monitor invested firms due to their short term profit orientation by utilizing 650 observations of taiwan banks this study examines the effects of specific types of ownership on the risk taking behaviours of banks under differential ownership structures in light of the increasing foreign institution ownership during privatization this article further constructs relative governance strength variables to observe how inside management and foreign institutions interact to affect these banks risk taking the results show that banks with higher inside management ownership and higher government ownership have higher overdue loan and lower capital adequacy ratios banks with higher foreign institution ownership and stronger relative governance strength are associated with lower overdue loans and higher regulatory capital in general the results a

power sector reform in south asia why slow and limited so far although south asian developing countries had initiated some form of electric power sector reform in the 1990s often under external lending agency pressures not much progress has been made so far and there is hardly any noteworthy example of a successful reform in the region this paper provides a brief review of power sector reform efforts in five south asian countries and uses an institutional economics framework to identify the factors shaping the success of power sector reforms four factors namely instability of rule makers poor overall acceptance slow adaptation and poor transition management are identified and their effect on the reform process of south asia are analysed the paper finds that political instability has affected the power sector reform of the region making hard decisions difficult to take slow progress of reform has also affected the sector viability as signs of adverse effects on the power sector investment and performance are already visible

low income homeownership american dream or delusion summary this paper is a critical analysis of recent us policy to promote low income homeownership it examines the ideology and assumptions buttressing this policy evidence on the effects of low income homeownership and the viability of homeownership as a strategy for low income families evidence suggests that the prospect for sustained growth in low income homeownership may be limited research does not provide uniform support for it as a tool for asset accumulation neighbourhood economic development or other social and political goals alleged effects of homeownership may be artefacts of self selection and the conflation of homeownership with unobserved characteristics coincident with buying homes what homeownership does and why are not well understood because of difficulties disentangling what homeownership means the elevation of low income homeownership to its current status has deflected political attention away from alternative policies for affordable housing

the impact of chinese carbon emission trading scheme ets on low carbon energy lce investment china is planning to introduce emission trading scheme ets to decrease co2 emission as low carbon energy lce will play a pivotal role in reducing co2 emissions our paper is to assess the extent and the conditions under which a carbon ets can deliver lce investment in china we chose wind technology as a case study and a real option based model was built to explore the impact of a number of variables and design features on investment decisions e g carbon and electricity price carbon market risk carbon price floor and ceiling and on grid ratio we compute critical values of these variables and features and explore trade offs among them according to our work a carbon ets has a significant effect on wind power plant investment although it cannot support investment in wind power on its own carbon price stabilization mechanisms such as carbon price floor can significantly improve the effect of carbon ets but the critical floor to support investment is still much higher than the carbon price in china pilot etss our results show that other policy measures will be needed to promote low carbon energy development in china

sectoral patterns of technical change towards a taxonomy and a theory abstract the purpose of the paper is to describe and explain sectoral patterns of technical change as revealed by data on about 2000 significant innovations in britain since 1945 most technological knowledge turns out not to be information that is generally applicable and easily reproducible but specific to firms and applications cumulative in development and varied amongst sectors in source and direction innovating firms principally in electronics and chemicals are relatively big and they develop innovations over a wide range of specific product groups within their principal sector but relatively few outside firms principally in mechanical and instrument engineering are relatively small and specialised and they exist in symbiosis with large firms in scale intensive sectors like metal manufacture and vehicles who make a significant contribution to their own process technology in textile firms on the other hand most process innovations come from suppliers these characteristics and variations can be classified in a three part taxonomy based on firms 1 supplier dominated 2 production intensive 3 science based they can be explained by sources of technology requirements of users and possibilities for appropriation this explanation has implications for our understanding of the sources and directions of technical change firms diversification behaviour the dynamic relationship between technology and industrial structure and the formation of technological skills and advantages at the level of the firm the region and the country

r d investment of electricity generating firms following industry restructuring abstract since electricity market restructuring questions over adequate levels of r d investments persisted using an unbalanced panel data of 70 electricity generating firms across 15 organisations of economic co operation and development countries from 1990 to 2008 this paper empirically examines the impacts of entry liberalization allowing third party access establishing a wholesale market and deregulating a retail market vertical unbundling privatization and firm size on r d investments entry liberalization is associated with a decline in r d investment establishing a wholesale market exhibits the greatest negative effects on r d investment regulated tpa and retail market deregulation also decrease r d the effect of privatization is not independently salient but interacts with a wholesale pool to lower r d investments large firms spend more on r d investment than small firms results indicate that the restructuring of the electricity industry reduces r d investment which may be detrimental to the reliability and the efficiency of the electricity system as well as to the creation and maintenance of the innovation capabilities necessary to address demand and environmental concerns

financial distress drivers in brazilian banks a dynamic slacks approach abstract this study applies the dynamic slacks based model dsbm developed by tone and tsutsui 2010 in order to assess the evolution of input saving output increasing potentials in major brazilian banks from 1996 to 2011 we propose that these potentials or slacks can be used as proxies for an eventual financial distress situation in the future the main research objective is to determine whether or not different characteristics of bank type related to ownership size and merger and acquisition processes are significantly related to inefficiency levels and by extension to an eventual financial distress situation since higher inefficiency levels also imply lower input saving output decreasing potentials based on a balanced panel model secondary data from economatica were collected and analyzed results indicate higher inefficiency levels and slacks in small public and national banks policy implications are also addressed

information or regulation what drives the international activities of commercial banks information costs and regulatory barriers distinguish international financial markets from national ones using panel data on bilateral assets and liabilities of commercial banks i empirically determine the impact of information costs and regulations and i isolate intra eu financial linkages i confirm that information costs and regulations are important factors influencing international asset choices of banks but their relative importance differs among countries

a dynamic stochastic frontier model to evaluate regional financial efficiency evidence from chinese county level panel data abstract studies have widely used stochastic frontier models to assess financial efficiency however traditional static approaches do not take dynamic characteristics of financial systems into account this article develops a dynamic stochastic frontier model to evaluate regional financial efficiency and provides an empirical test of the model by using panel data of 62 chinese counties during the 2001 2010 period the model measures the dynamic impact of the input output variables and environmental variables on financial efficiency and allows for the separation of technical change from the change in technical efficiency the results show that the dynamic model provides a better fit to the data than the static model in addition a gradient difference emerges in the regional financial efficiency among the six major regions of china the results offer practical implications for the development of regional financial services in china as well as other developing countries and emerging economies

status of electricity act 2003 a systematic review of literature abstract the electricity act 2003 was a landmark act which promised to remove the maladies which afflict the indian power sector and that too at a time when the sector was ridden with problems with concepts such as open access multiple distribution licensees wheeling of electricity etc the said act intended to encourage competition which in turn was meant bring a paradigm shift in the sector the paper undertakes a systematic literature review to find the status of review of the promising act more than a decade has passed since its enactment and amendments are due with the legislative body of india but none of the literature reviewed gives a comprehensive view encompassing all the objectives of the act moreover these documents study either the probable impact or the impact on a particular segment only it has important implications for the power sector which highlights a significant gap in literature and provides a basis on which future research can be built upon

why european banks are less profitable than u s banks a decomposition approach abstract the low profitability of european banks relative to their u s counterparts has recently raised concerns among policy makers and researchers this paper attempts to shed light on this issue by using the o donnell 2012 decomposition approach this approach enables us to decompose the relative profitability of european banks into an output input price index and a total factor productivity index with the former further decomposed into two price indexes and the latter further into four productivity and efficiency measures our results show that european banks profitability was not only weak but also deteriorated over time our further analysis shows that the decline in the output input price index was due to declines in relative lending rate and relative return on securities and an increase in funding costs while the decline in the productivity index was driven by declines in technical efficiency scale efficiency and residual mix efficiency

what triggers environmental management and innovation empirical evidence for germany abstract it is frequently hypothesized that environmental management systems emss may improve firms environmental innovation performance whether this hypothesis is true is as critical for environmental policy as questions pertaining to the relevant incentives for 1 a firm s voluntary adoption of an ems and 2 its environmental innovation behavior based on ample empirical evidence for german manufacturing this paper addresses the simultaneity of these issues on the basis of a recursive bivariate probit model that explores the hypothesis that a facility s decision on innovation activities is correlated with the decision on ems adoption our empirical results indicating that environmental innovation activities are not associated with ems implementation nor any other single policy instrument reflect the perceptions of the survey respondents and hence should be interpreted as correlations rather than causal relationships according to these perceptions innovation behavior seems to be mainly correlated with the stringency of environmental policy

relative income effects on subjective well being in the cross section abstract recent work suggests that a person s subjective well being swb depends to a large degree on relative income focusing on the underlying identification this paper makes four contributions to this literature it describes the aggregation problem with past studies implements an estimation strategy to overcome this problem finds micro level evidence in support of the hypothesis that relative income does matter in individual assessments of swb and uses cross section estimates to replicate the aggregate time series the evidence further indicates that relative income effects may be smaller at low income levels the results are obtained from ordered probit techniques and the general social survey gss

an overview of incentive policies for the expansion of renewable energy generation in electricity power systems and the brazilian experience abstract energy production from renewable sources is already a reality in many countries and with that different strategies for incentivizing investments in renewable energy generation have been proposed and used over the years in this study long term policies that have been applied in several countries such as feed in tariffs shares with commercialization of certificates auctions and net metering are overviewed and discussed the main advantages and disadvantages of these incentive strategies are emphasized focusing on applications some of these strategies that have already been applied in brazil are analyzed in greater depth emphasizing the potentialities and fragilities of these mechanisms observed within the country even though it is a country that stands out in relation to other latin american countries regarding electricity generation from non hydro renewable sources brazil still faces barriers that prevent a utilization compatible with its potential moreover the trend for renewable sources such as wind and solar power is to represent an energy capacity reserve to cover hydrological risks and also to contribute to a distributed generation spread through electricity distribution networks

is more always better a survey on positional concerns abstract we use survey data to provide some empirical information about concerns regarding relative standing respondents chose between a world where they have more of a good than others and one where everyone s endowment of the good is higher but the respondent has less than others questions asked about education attractiveness and intelligence for one s child and oneself income vacation time approval and disapproval from a supervisor and papers to write half of the respondents preferred to have 50 less real income but high relative income concerns about position were strongest for attractiveness and supervisor s praise and weakest for vacation time

structural changes in the power sector in asia improving profitability this study determined the characteristics of profitable electric utilities and those with low power rates in the dynamic asia pacific region it also examined current reforms notably structural changes regulation and privatization which are reshaping the power industry in asia the paper suggests that power industry reforms should propel electric utilities to success by also addressing the critical factors necessary for utilities to attain optimum profitability and competitive tariffs cross section analysis of utilities in asia shows that the biggest barrier to achieving higher profits is systems loss followed by inflation proportion of purchased power expense and fuel expense privately owned utilities and those in countries with a ministry of energy are also found to be more profitable according to utilities surveyed government can help utilities by granting them more autonomy equity better guidelines for ipps a more independent regulatory body less frequent changes in top management stricter laws on pilferage and tariff relief

a review of renewable energy investment in the brics countries history models problems and solutions abstract this paper reviews the history of renewable energy development in the brics countries the financing models for renewable energy development of brics countries include bank financing institutional loans industry funds and international financing this paper identified several problems with financing in brics countries including a lack of financing channels investment shortage for small and medium sized enterprises and imperfect government policies the solutions to these problems include expanded capital markets the financing of leasing services and build operate transfer and build own operate projects further a financial citizen participation model should be employed similar to that as germany and european union emissions trading system eu ets a financial citizen participation model means that legal entities private individuals and agricultural enterprises invest in renewable energy infrastructure through equity a regional reserve ratio monetary policy is suggested to allow regions to develop renewable energy

the impact of liberalization on the productive efficiency of indian commercial banks abstract we examine the productive efficiency of 70 indian commercial banks during the early stages 1986 1991 of the ongoing period of liberalization we use data envelopment analysis to calculate radial technical efficiency scores we then use stochastic frontier analysis to attribute variation in the calculated efficiency scores to three sources a temporal component an ownership component and a random noise component we find publicly owned indian banks to have been the most efficient followed by foreign owned banks and privately owned indian banks we also find a temporal improvement in the performance of foreign owned banks virtually no trend in the performance of privately owned indian banks and a temporal decline in the performance of publicly owned indian banks we attempt to explain these patterns in terms of the government s evolving regulatory policies

the role of distribution network operators in promoting cost effective distributed generation lessons from the united states of america for europe abstract this paper explores the different competitive mechanisms applied by electric utilities from the us in promoting cost effective distributed energy resources der with a focus on distributed generation dg and the challenges that electric utilities are facing due to the increase in dg connections cases studies from california oregon colorado and new york have been selected the case studies refer to two kinds of competitive mechanisms request for proposals rfp and auctions renewable auction mechanism a similar behaviour is observed across electric utilities in the way in which competitive auction mechanisms are being managed however the more sophisticated auction designs are observed in the rfps the study proposes a set of auction design elements with a focus on the uk context and examines the role of energy regulators in the design of well structured auction mechanisms we think that the experience cited in the four case studies can be replicated by distribution system operators dsos from europe however unbundling rules established in the european commission third energy package need to be taken into consideration

assessing productive efficiency of banks using integrated fuzzy dea and bootstrapping a case of mozambican banks performance analysis has become a vital part of the management practices in the banking industry there are numerous applications using dea models to estimate efficiency in banking and most of them assume that inputs and outputs are known with absolute precision here we propose new fuzzy dea level models to assess underlying uncertainty further bootstrap truncated regressions with fixed factors are used to measure the impact of each model on the efficiency scores and to identify the most relevant contextual variables on efficiency the proposed models have been demonstrated using an application in mozambican banks to handle the underlying uncertainty findings reveal that fuzziness is predominant over randomness in interpreting the results in addition fuzziness can be used by decision makers to identify missing variables to help in interpreting the results price of labor price of capital and market share were found to be the significant factors in measuring bank efficiency managerial implications are addressed

the innovation effects of environmental policy instruments a typical case of the blind men and the elephant abstract in this paper we examine the innovation effects of environmental policy instruments in four literatures theoretical models on incentives for eco innovation econometric studies based on observed data survey analysis based on stated information and technology case studies the aim of this paper is to critically examine the methods and the results we argue that the case studies literature even when its results are specific and difficult to generalise is a necessary source of empirical evidence about policy impacts and the factors responsible for these impacts pointing to issues that are neglected in the theoretical and econometric literature such as the specifics of the innovation context and policy interaction effects the paper states five synthesised findings and makes a plea for multi method analysis one other important synthesised finding is that the influence of market based instruments on innovation such as emission trading and taxes is far weaker than assumed

productivity change and its determinants among leading mobile operators in europe the european mobile telecommunications industry has seen increased competition and market saturation in recent years so improving productivity will become crucially important for mobile operators in the near future this study adopts a bootstrap malmquist index approach to estimate productivity change among a sample of 23 of europe s leading mobile operators over the 2008 to 2009 period using a second stage regression this article also analyses the determinants of productivity changes in terms of regulation competition and ownership structure the results show that mobile companies operating in countries that have recently joined the eu have a positive association with productivity change in contrast to their counterparts in south east europe concerning market competition the leading mobile operators that experience higher productivity changes operate in more concentrated markets the results also indicate that international mobile operators perform better in terms of productivity change than their

impact of financial reforms on efficiency of state owned private and foreign banks in pakistan this article uses a unique bank level data from 1991 to 2000 and evaluates how financial reforms affect banking efficiency of domestic and foreign banks in pakistan the results suggest that banking efficiency falls during initial reform period when banks adjust to enhanced competition but increases in more advanced stages of reform while in general foreign and private banks show superior efficiency and factor productivity than do state owned banks the relative performance of foreign banks worsens after the consolidation stage of the financial reforms is over we show the importance of link between bank size asset quality and bank branches with efficiency indexes and also note that every 10 increase in share of nonperforming to total loans decreases banking efficiency by 6 to 10

meeting electrification s social objectives in south africa and implications for developing countries electrification programmes and projects are usually planned and evaluated on the basis of their economic financial and socio economic performance it is not usually recognised that electrification is often carried out for social objectives of poverty alleviation and political effect examination of electrification in south africa reveals clearly that initial electrification was to meet economic objectives later socio economic objectives were adopted and recently the objectives were social social electrification particularly rural electrification is not viable according to usual assessment methods which are frequently distorted to provide the justification for a project to proceed the technology of network electrification changed to meet the constraints challenging usual perceptions about the relative costs of urban and rural electrification and the potential for photovoltaic electrification adopting a specification for social electrification allows suitable tariffs for electrification to be identified indicates how capital investment decisions might be modified for social electrification and identifies implications for electricity industry restructuring a better understanding of electrification s social objectives has implications for projects and programmes in other developing countries

wheeling of power under deregulated environment of power system a bibilographical survey the power industry is moving rapidly from regulated conventional setup to a deregulated environment there is an urgent need to keep a track of international experiences and activities taking place in this emerging field this paper gives a bibliographical survey and general backgrounds of research and development in the field of power system wheeling under deregulated environment based on over 170 published articles wheeling in general and the establishment of wheeling rate in particular are subjects of extensive debate today this will be very much useful for all countries especially those developing countries which are moving toward the unbundling of electricity supply industry esi the collected literature have been divided into many section so that new researchers do not face any difficulty for obtaining literature particularly in the area of wheeling of power under deregulated environment

scale economies in electricity distribution a semiparametric analysis we estimate the costs of distributing electricity using data on municipal electric utilities in ontario canada for the period 1993 5 the data reveal substantial evidence of increasing returns to scale with minimum efficient scale being achieved by firms with about 20 000 customers larger firms exhibit constant or decreasing returns utilities which deliver additional services such as water sewage have significantly lower costs indicating the presence of economies of scope our basic specifications comprise semiparametric variants of the translog cost function where output enters non parametrically and remaining variables including their interactions with output are parametric we rely upon non parametric differencing techniques and extend a previous differencing test of equality of non parametric regression functions to a panel data setting copyright 2000 john wiley sons ltd

economic instruments and induced innovation the european policies on end of life vehicles abstract the paper addresses the mechanisms by which specific economic instruments based on the producer responsibility principle prp can influence innovation when environmental policy has impact on very complex industrial subsystems we consider the eu policy on end of life vehicles directive 2000 53 ec on elvs as a representative case study of multiple industry prp instrument dynamic efficiency problems in order to achieve ambitious policy targets on elv recovery recycling reuse interrelated sequences of single innovations in both upstream car making and downstream car recycling recovery should take place we explore the extent to which the introduction of a free take back ftb instrument can influence industrial actors in contributing to innovation paths that are still marked by technological uncertainty evolving capabilities and different cost benefit balances for actors themselves we conclude that differently from static approaches in which the ei and its formulation is neutral with respect to policy effectiveness the dynamic efficiency of eis in elv like problems depends both on where along the production to waste chain and how in terms of net cost allocation the specific incentive is introduced consequently in order to generate a policy desired innovation path the way in which the ei related incentive allocated to a certain industry is transmitted to other industries whether upward or downward along the chain is also relevant disregarding these effects can imply a dissipation of innovation incentives and the generation of regulation induced rents for some actors cannot be ruled out policies based on prp should consider eis in conjunction with enforceable voluntary agreements

home ownership as a social norm and positional good subjective wellbeing evidence from panel data much attention has been devoted to examining the absolute benefits of home ownership e g security and autonomy this paper by contrast is concerned with conceptualising and testing the relative benefits of home ownership those benefits that depend on an individual s status in society home ownership has previously been analysed as a social norm implying that the relative benefits costs associated with being an owner renter are positively related to relevant others home ownership values the theoretical contribution of this paper is to additionally conceptualise home ownership as a positional good implying that the status of both home owners and renters is negatively related to relevant others home ownership consumption the empirical contribution of this paper is to quantitatively test for these relative benefits in terms of subjective wellbeing we run fixed effects regressions on three waves of the british household panel study we find that 1 a strengthening of relevant others home ownership values is associated with increases decreases in the subjective wellbeing of home owners renters and 2 an increase in relevant others home ownership consumption decreases the life satisfaction of owners but has no effect for renters overall our findings suggest that 1 the relative benefits of home ownership are both statistically significant and of a meaningful magnitude and 2 home ownership is likely to be both a social norm and a positional good without explicitly recognising these relative benefits policymakers risk overestimating the contribution of home ownership to societal wellbeing

efficiency and credit rating in taiwan banking data envelopment analysis estimation in this article we use the data envelopment analysis to measure the efficiency of banks before and after credit rating is taken into consideration and we also employ the malmquist productivity index to measure the total factor productivity changes from 2001 to 2003 the results are as follows 1 there is a positive relationship between the efficiency scores and credit rating and thus the credit rating can be a representative to evaluate the performance and quality of a bank 2 we use the wilconxon two sample test of nonparametric statistic to test the influences of credit rating the empirical result shows that the credit rating is proven to influence the efficiency of banks 3 the efficiency scores improve in both investment grade above tw bbb and speculation grade under tw bbb when credit rating is taken into consideration the empirical results show that the efficiency scores of banks with a high credit rating improved relatively more when compared to banks with a lower credit rating

evaluating the cost efficiency of the italian banking system what can be learned from the joint application of parametric and non parametric techniques abstract research on bank efficiency has developed in two separate streams econometric studies and data envelopment analysis a linear programming technique these two branches of literature have developed quickly but separately in this paper these two approaches have been tested on a common panel of 270 italian banks and this has suggested the following i econometric and linear programming results do not differ dramatically when based on the same data and conceptual framework ii when differences arise they can be explained by going back to the intrinsic features of the models moreover some findings on italian banks may be of interest also to the international reader i efficiency scores show a high variance ii the banking system is split in two between northern and southern banks iii there is a direct rather than inverse relationship between productive efficiency and asset quality iv the efficiency of italian banks did not increase over the period 1988 1992

determinants of environmental innovation new evidence from german panel data sources abstract in most cases empirical analyses of environmental innovations based on firm level data relied on surveys for one point in time these surveys allow for the inclusion of many explanatory variables such as different policy instruments or the influence of pressure groups but it is not possible to address the dynamic character of environmental innovations this paper uses two german panel databases the establishment panel of the institute for employment research iab and the mannheim innovation panel mip of the centre for european economic research zew to explore the determinants of environmental innovations the econometric estimations show that the improvement of the technological capabilities knowledge capital by r d triggers environmental innovations environmental regulation environmental management tools and general organizational changes also encourage environmental innovation a result that has also been postulated by the famous porter hypothesis

the social and private micro level consequences of homeownership abstract this paper reviews the literature that describes the micro level economic and social consequences of homeownership we adopt an interdisciplinary approach and include studies from economics sociology geography political science psychology and other disciplines our focus is on the set of consequences of homeownership in developed countries our list of potential outcomes of homeownership includes the impact on household wealth and portfolio choice mobility labor force participation urban structure and segregation home maintenance political and social activities health demographics self esteem and child outcomes there is substantial evidence that homeownership has important effects on some household behaviors and outcomes however we find that much of the past 30 year s literature on consequences of homeowning is deficient from a theoretical or econometric perspective we suggest solutions and identify research gaps present in the literature

a ten year rule to guide the allocation of eu emission allowances abstract member states in the european union eu are responsible for national allocation plans governing the initial distribution of emission allowances in the co2 emission trading system including rules governing allocations to installations that close and to new entrants the european commission has provided guidelines to discourage the use of allocation methodologies that provide incentives affecting firms compliance behavior for example by rewarding one type of compliance investment over another we find that the treatment of closures and new entrants by member states is inconsistent with the general guidelines provided by the eu we propose stronger eu guidance regarding closures and new entrants a more precise compensation criterion on which to justify free allocations and a ten year rule as a component of future eu policy that can guide a transition from current practice to an approach that places greater weight on efficiency

wto challenges and efficiency of chinese banks after joining the world trade organisation wto in december 2001 china was given 5 years to completely open up its banking market for international competition chinese banks have been renowned for their mounting nonperforming loans and low efficiency despite gradual reforms the banking system is still dominated by state ownership and encapsulated monopolistic control how to raise efficiency is a key to the survival and success of domestic banks especially the state owned commercial banks two important factors may be responsible for raising efficiency ownership reform and hard budget constraints this article uses a panel data of 22 banks over the period 1995 to 2001 and employs a stochastic frontier production function to investigate the effects of ownership structure and hard budget constraint on efficiency empirical results suggest that nonstate banks were 8 18 more efficient than state banks and that banks facing a harder budget tend to perform better than those heavily capitalized by the

a closer look at small hydropower projects in india social acceptability of two storage based projects in karnataka abstract associated with being green clean and small scale small hydroelectric power shp projects generally enjoy a positive image in india shp promises answers to issues such as meeting a growing electricity demand facilitating lucrative investment opportunities and climate change considerations the features of being green clean and small scale have contributed to the assumption of shp as an essentially uncontested technology empirical studies questioning this assumption are scarce research on shp has so far remained rather hypothetical and policy level focused this article investigates the social acceptability of small hydroelectric plants in india by empirically looking at how people engage with these plants it thereby underlines the importance of studying technologies in their local context based on a detailed case study analysis of two shp projects in karnataka india the article shows how shp projects are contested on the local level the engagement of local people played a crucial role in the contestation of the plants and led to significant and unexpected outcomes and effects the article highlights the importance of having a broader perspective in the development of shp that goes beyond a mindset of technological fixes this includes taking account of existing water infrastructure and a broader range of water users the article shows that the implementation of shp projects does not take place in a void rather complex existing physical and social realities on the ground matter for the development and performance of shp

exploring the nexus between banking sector reform and performance evidence from newly acceded eu countries abstract the aim of this study is to examine the relationship between banking sector reform and bank performance measured in terms of efficiency total factor productivity growth and net interest margin accounting for the effects through competition and bank risk taking to this end we develop an empirical model of bank performance which is consistently estimated using recent econometric techniques the model is applied to bank panel data from ten newly acceded eu countries the results indicate that both banking sector reform and competition exert a positive impact on bank efficiency while the effect of reform on total factor productivity growth is significant only toward the end of the reform process finally the effect of capital and credit risk on bank performance is in most cases negative while it seems that higher liquid assets reduce the efficiency and productivity of banks

beyond technology push and demand pull lessons from california s solar policy abstract the scale of the technological transformation required to reduce greenhouse gas emissions to safe levels while minimizing economic impacts necessitates an emphasis on designing climate policy to foster or at least not impede environmental innovation there is only a weak empirical base for policy makers to stand on regarding the comparative innovation effects of various climate policy options however empirical scholarship in environmental innovation is hindered by the complexity of both the innovation process and the interactions between the dual market failures of pollution and innovation that are in play and it appears that the field would benefit from the structure provided by a common lexicon this paper focuses on the issues related to policy categorization in this field these issues have received little attention in the literature despite their importance to making insights gained from empirical studies generalizable the paper reviews the origins strengths and weaknesses of the dominant policy typology of technology push versus demand pull instruments its primary contribution however is to assemble a comprehensive chronology of solar policy in california and its impacts on innovation where known and then use this as a basis for building a new policy categorization that takes advantage of the intuitive resonance of the dominant typology while encompassing the broader range of policy instruments that are employed in practice in order to stimulate environmental innovation the most noteworthy aspect of the new categorization is that it introduces a third category of environmental innovation policy instrument that focuses on improving the interface between technology suppliers and users this reflects developments in the economics of innovation literature as well as considerable evidence in the domain of distributed solar energy technologies that opportunism by some of the actors that work at this interface can be a barrier to innovation

experience with smarter commercial arrangements for distributed wind generation abstract this study explores different practices for accelerating the integration of generating facilities to the electricity network using smart solutions case studies from great britain republic of ireland and northern ireland and the unites states of america were selected the paper assesses and compares the different principles of access that have been implemented in these countries such as last in first out lifo pro rata and market based the social optimality of these approaches is also discussed the paper also evaluates how the risk regarding curtailment and investment is allocated between parties distribution network operators generators and customers even though the cases are diverse important findings and lessons have been identified which may assist distribution network operators to address the issue of increasing the connection of distributed generation while managing efficiently and economically energy exports from generators

current status and analysis of renewable promotional policies in indian restructured power sector a review restructuring has changed the traditional mission and mandates of power utilities in complex ways and had large impacts on environmental social and political conditions for any particular country at the same time new regulatory approaches are being found for reducing environmental impacts in restructured power sectors india has a vast supply of renewable energy resources and it has one of the largest programs in the world for deploying renewable energy based products and systems so this paper attempts to review the various policies and measures undertaken by indian government for promotion of renewable energy the aim of this paper is also to review the current policy mechanisms especially investment or generation based price driven and capacity driven mechanisms ranging from investment incentives for the development of renewable energy projects feed in tariffs production tax incentives tradable green certificates and their effects upon the prospects of encouraging as well as expanding the development of renewable energy in indian restructured power sector this will make renewable more attractive in the indian future electricity market

examining the role of policy design and policy interaction in eu automotive emissions performance gaps in the wake of the 2015 dieselgate scandal the us and european governments publicly confronted automakers about their behaviour which raised concerns about the integrity of the current emissions legislation regimes in this article i argue that flexibilities within the eu s emissions legislative framework afforded automakers the opportunity to legally sidestep strict performance standards laid out in the law and resulted in a significant performance gap in real world driving emissions this article provides a timely examination of eu emission legislation policy design and policy interaction within the european union with the aim of explaining why the eu policy framework failed to regulate the regional automotive industry current research is mostly concerned with the typology and effectiveness of individual environmental policy instruments be it regulatory or economic incentives that aim to influence industry behaviour this article approaches the current eu policy regime in a more holistic manner and focuses on the exploitation of weaknesses in the regulatory framework by private firms which has received little academic attention in the innovation and transition literature a major contribution of this article therefore is a body of primary qualitative interview data from industry elites concerning relevant emissions policies

consistency in performance rankings the peru water sector regulators can utilize a number of alternative methodologies for comparing firm efficiency but these approaches need to be robust to be accepted by stakeholders this study evaluates the consistency of water utility performance rankings for peruvian water utilities the results indicate that data envelopment analysis dea and stochastic frontier analysis sfa yield similar rankings in this case in addition the techniques have comparable success for identifying the best and worst performing utilities however these rankings based on sophisticated statistical techniques are not highly correlated with those developed by the peruvian water regulator sunass this result does not invalidate the performance rankings obtained by the regulator since those rankings are based on more dimensions of utility performance however they illustrate the importance of developing sound techniques for identifying weak utilities improvements in sector performance require that benchmarking be given greater attention t

financing the energy sector in developing countries context and overview abstract traditional business as usual financing methods will no longer be adequate to meet the unprecedented demands for capital to finance energy sector expansion in the developing countries in recognition many countries are opening up their power sectors to private investment initially through the establishment of independent power projects but in some cases through sector privatization project financing has many advantages but further sectoral reorganization including tariff reform will be needed to attract resources on the scale required especially from domestic investors in oil and gas in contrast to power private capital from the international oil companies has always played a major role in the developing countries however sharply increasing investment requirements require a growing role for external finance there should in principle be no shortage of investible funds to finance energy sector expansion in developing countries so long as host countries establish conditions which are attractive to private investors the augmented role of private finance requires a continuing if different role for the public sector in both host countries and official aid agencies

dynamic incentives by environmental policy instruments a survey abstract in this paper i survey and discuss recent developments on the incentives provided by environmental policy instruments for both adoption and development of advanced abatement technology a main conclusion to be drawn from the literature is that under competitive conditions market based instruments usually perform better than command and control moreover taxes may provide stronger long term incentives than tradable permits if the regulator is myopic if the government can anticipate new technology or is able to react on it optimally regulatory policies by virtue of administered prices taxes and policies by setting quantities issuing tradable permits are almost equivalent the literature also shows that under competitive conditions there is no difference between auctioning permits and grandfathering moreover timing and commitment of environmental policy is not crucial for adoption under competitive conditions commitment has positive incentive effects however if an r d sector has market power in the presence of market imperfections the ranking of the different policy instruments is ambiguous

effects of regulatory reforms in the electricity supply industry on electricity prices in developing countries electric power sector reforms in the electricity supply industry have had an impact on industrial and household prices in developing countries in latin america the former soviet union and eastern europe using original panel data for 83 countries during the period from 1985 to 2002 we examine how each policy instrument of the reform measures influenced electricity prices for countries in the above regions we found that variables such as entry of independent power producers ipp unbundling of generation and transmission establishment of a regulatory agency and the introduction of a wholesale spot market have had a variety of impacts on electricity prices some of which were not always consistent with expected results the research findings suggest that neither unbundling nor introduction of a wholesale pool market on their own necessarily reduces the electric power price in fact contrary to expectations there was a tendency for the price to rise however coexistent with an independent regulator unbundling may work to reduce electricity prices privatization and the introduction of foreign ipp and retail competition lower electricity prices in some regions but not all

review of proposals for practical power sector restructuring and reforms in a dynamic electricity supply industry abstract south africa s electricity supply industry esi remains a vertically integrated monopoly despite global trends towards restructuring the monopolistic nature of the esi could hinder the development of distributed power systems as penetration of renewable electricity increases the research aims to rationalise south africa s esi evolution propose practical power sector restructuring in the short to medium term and to determine their potential impact the research methodology included a single case study instrument with embedded sub units of analysis primary research data was gathered using semi structured interviews with industry experts in addition to which secondary data from government documents and archival records were used for triangulation research results conclude that south africa s esi grew due to techno economic industrialisation factors while apartheid era policies influenced the esi in only some specific respects the vertically integrated status quo was sustained in the post transformation period due to government s focus on social imperatives lack of regulatory policy certainty and conflicts in political ideology south africa did not experience the pre conditions that triggered global power sector reforms in the late 20 th century but these pre conditions are now becoming evident privatisation of eskom generation and introduction of wholesale and retail competition are not practical in the short to medium term proving the infeasibility of the standard model of reform locally the introduction of an independent system and market operator ismo using a single buyer model is seen as the most favourable and practical option with the ismo owning transmission infrastructure the research suggests that esi changes will increase system efficiencies economic performance and private sector involvement but will not reduce electricity tariffs the scenarios challenges and proposals identified in this research are also applicable to other countries in africa and other developing regions of the world that have similar social and political backgrounds ensuring sustainable supply of electricity

the arguments for and against ownership unbundling of energy transmission networks abstract the question this paper addresses is what is the evidence for the superiority of the ownership unbundled transmission models i e uk or nord pool hybrid over other models we assess the theoretical costs and benefits of ownership unbundling and judge these to be generally positive though these may be potentially offset by the actual reorganisation costs of the ownership unbundling process next we assess the empirical evidence this is in two forms econometric evidence from samples of countries and case studies of reforms in particular jurisdictions the econometric evidence is weak due to problems with simultaneity of reform steps and a lack of studies but the case study evidence is compelling we conclude with a discussion of the issues faced by countries considering implementing ownership unbundling we conclude that evidence seems to be that ownership unbundling of transmission is a key part of energy market reform in the most successful reform jurisdictions

demise of the standard model for power sector reform and the emergence of hybrid power markets following earlier reforms in the power sectors of industrialized countries and emerging markets e g chile developing countries were encouraged to unbundle their electricity industries and to introduce competition and private sector participation this paper highlights the developments that led to how power sector reform came to be defined as a standard model and theoretical framework in its own right and how the model was used prescriptively in many developing countries however we also show that after more than 15 years of reform efforts this new industry model has not fully taken root in most developing countries finally we identify and characterize the emergence of new hybrid power markets which pose fresh performance and investment challenges

estimating the wetland rental fee a case study involving a taiwan wetland wetlands provide many functions that are both economic and recreational and are valuable in terms of their ecological diversity while at the same time being nonmarket value products the purpose of this study is to estimate the optimal wetland rental through estimations of both the demand and supply functions in relation to wetland the wetland supply function is directly estimated based on the data provided by the owners of the wetland while the estimation of the wetland input demand function involves using the bootstrapping and contingent visitation approaches such estimation approaches could also be applied to other nonmarket value products that give rise to environmental externalities the estimation of rental fee could provide a long term leasing contract that gives the landlord with a particular rent to lease their lands to support a wetland eco tourism park to maintain wetland for substantial management several environmental management policy implications are also addressed

emergence of financial markets for electricity a european perspective abstract deregulation directed at european energy markets is proceeding although the speed often may seem slow real changes are coming in the development of physical and especially financial markets for electricity electricity deregulation started in individual countries notably the united kingdom and norway and the norwegian effort spread to the rest of the nordic region before the union s 1996 electricity directive started to have a real impact electricity deregulation is a complicated process involving breaking up of generation monopolies unbundling of generation and transmission consumer choice of suppliers through local distributors and eventually perhaps the establishment of a power pool where physical as well as financial contracts are traded the deregulation process now has gone far enough to reap some experiences the original uk deregulation model which focused mainly on breaking up the generation monopoly proved somewhat inefficient because it didn t offer real consumer choices and opened for inefficient gaming strategies among producers this experience has pushed the united kingdom in the direction of the nordic model norwegian deregulation is peculiar in the sense that new entry to generation is highly restricted on the other hand norway now with the entire nordic region has developed a quite advanced and quite well functioning electricity trading pool with widespread financial trading and good liquidity part of the success of the nordic model comes having a high quality spot price which can be used as a benchmark for the pricing of financial contracts another possible source of success is the high proportion of hydropower for which production volumes can be adjusted quickly and outages and price spikes thus avoided the swiss experience further underscores the importance of a spot price benchmark because the extensive swiss physical trade has allowed a growing volume of contract trade even in the absence of deregulation from these experiences we propose four factors we believe to be instrumental in creating healthy financial power markets the choice of pool model including spot adjustment and forward markets will make or break liquidity a price index is essential for ensuring transparency standardized simple derivative contracts make trading easier and more attractive finally the underlying physical system is important a hydro based system is easy to adjust while a thermal system will have problems with security of supply although the process is slow deregulation is likely to change the european electricity market in profound ways we see the effects mostly as beneficial deregulation will improve efficiency in generation will improve transparency for better consumer choices and allow the emergence of efficient financial trade in electricity if deregulation is all that s done the environmental effects may be adverse because lower prices encourage greater consumption and hence emissions coupled with a sensible environmental policy we believe deregulated markets can minimize the costs of environmental protection

electricity distribution industry restructuring in south africa a case study for 20 years there has been vigorous debate about restructuring the large developed electricity industry in south africa but the plans have not been implemented the justification of the proposed restructuring illustrates the different expectations of the participants in the electricity industry the case study reviews what has occurred against a background of some theories about organisations and identifies six key issues some lessons include the need to adopt an industry structure compatible with the objectives of electricity distribution in developing countries the unsuitability of orthodox approaches to organisations that no industry structure appears to be significantly better than others industry restructuring of public sector utilities has a significant political dimension restructuring can fail even if there is support from a high level of government and indecision and uncertainty have serious negative consequences the experience should be helpful for other developing countries considering structural change of their electricity industry

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
