judicial productivity delay and efficiency a directional distance function ddf approach abstract the aim of this paper is twofold on the one hand it provides a contribution to the debate on judicial efficiency by conducting an applied research on the italian tax judiciary thanks to a database covering the activities of the italian tax courts over a 3 year period 2009 2011 on the other hand it also contributes to the methodological debate as it compares results obtained with data envelopment analysis dea and directional distance function ddf two related non parametric techniques which allow evaluating the efficiency of each observation as the radial distance from the efficient frontier defined by the best observations while dea has already been used to assess the mere technical efficiency of judicial systems the ddf offers a valuable additional contribution since it makes it possible to minimize the social cost of production of adjudication in the measurement this feature makes it particularly attractive in those sectors in which production externalities may arise such as judicial delays in the case investigated here additionally the paper first applies the bootstrap to the ddf procedure in order to provide more robust estimates and to compare them with the dea results

efficiency of the medical care industry evidence from the italian regional system abstract what might be the relation between clinical research and efficiency of medical care suppliers is the hypothesis of a positive relation consistent considering efficiency as the supplier s ability to maximize the number of patients hospitalized in a mobility process among regions i e mobility balance this work aims at highlighting the existence of a positive externality of pharmaceutical clinical research on that kind of efficiency in other words an externality is able to affect the patients perception of good bad quality of outputs supplied by the medical care industry leading their mobility process taking italy and the mobility of patients among regions into account an operational research study will be performed in order to support this assumption the goal of this work is to show an alternative way to increase the efficiency of medical care suppliers on the market of health care that is to say through their competitiveness on the market of human experimentation

some models for estimating technical and scale inefficiencies in data envelopment analysis in management contexts mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best in this capacity mathematical programming serves as a planning aid to management data envelopment analysis reverses this role and employs mathematical programming to obtain ex post facto evaluations of the relative efficiency of management accomplishments however they may have been planned or executed mathematical programming is thereby extended for use as a tool for control and evaluation of past accomplishments as well as a tool to aid in planning future activities the ccr ratio form introduced by charnes cooper and rhodes as part of their data envelopment analysis approach comprehends both technical and scale inefficiencies via the optimal value of the ratio form as obtained directly from the data without requiring a priori specification of weights and or explicit delineation of assumed functional forms of relations between inputs and outputs a separation into technical and scale efficiencies is accomplished by the methods developed in this paper without altering the latter conditions for use of dea directly on observational data technical inefficiencies are identified with failures to achieve best possible output levels and or usage of excessive amounts of inputs methods for identifying and correcting the magnitudes of these inefficiencies as supplied in prior work are illustrated in the present paper a new separate variable is introduced which makes it possible to determine whether operations were conducted in regions of increasing constant or decreasing returns to scale in multiple input and multiple output situations the results are discussed and related not only to classical single output economics but also to more modern versions of economics which are identified with contestable market theories

why did the energy intensity fall in china s industrial sector in the 1990s the relative importance of structural change and intensity change there have been a variety of studies investigating the relative importance of structural change and real intensity change to the change in china s energy consumption in the 1980s however no detailed analysis to date has been done to examine whether or not the increased energy efficiency trend in the 1980s still prevailed in the 1990s this article has filled this gap by investigating the change in energy consumption in china s industrial sector in the 1990s based on the data sets of value added and end use energy consumption for the 29 industrial subsectors and using the newly proposed decomposition method of giving no residual our results clearly show that the overwhelming contributor to the decline in industrial energy use in the 1990s was the decline in real energy intensity indicating that the trend of real energy intensity declines in the 1980s at the 2 digit level was still maintained in the 1990s this conclusion still holds even if we lower the growth rate dramatically in line with the belief that the growth rate of china s gdp may be overestimated

index decomposition analysis applied to co2 emission studies index decomposition analysis ida was first extended from energy consumption to energy related co2 emission studies in 1991 since then many studies have been reported covering various countries and emission sectors however unlike the case of energy consumption studies a comprehensive literature survey that focuses specifically on emission studies has so far not been reported in this paper we attempt to fill this gap by reviewing 80 papers appearing in peer reviewed journals from 1991 to 2012 in this application area the first part of this paper deals with the developments with regard to the ida approaches used by researchers and the scope and focus of their studies in the second part the empirical results reported in the surveyed studies are analyzed consolidated and presented by emission sector the objective is to reveal the relative contributions of key effects on changes in the aggregate carbon intensity and this is done by emission sector and by country the findings of both parts are useful in understanding the development of ida in the application area of emission study as well as the key drivers of aggregate carbon intensities in the past and their possible future developments

nontraditional activities and the efficiency of us commercial banks abstract in recent years an increasing portion of bank income has been generated through nontraditional activities most studies of bank efficiency do not include any measure of nontraditional activities when measuring outputs in this paper cost revenue and profit efficiency are estimated by using models with and without nontraditional output the results suggest that the standard model which omits nontraditional output understates bank efficiency evidence also surfaces that based on efficiency the relative ranking of individual banks changes when nontraditional activities are included as a type of output

on the determinants of local government performance a two stage nonparametric approach abstract this article analyzes the efficiency of local governments in the comunitat valenciana spain and their main explanatory variables the analysis is performed in two stages firstly efficiency is measured via nonparametric activity analysis techniques specifically we consider both data envelopment analysis dea and free disposable hull fdh techniques the second stage identifies some critical determinants of efficiency focusing on both political and fiscal policy variables in contrast to previous two stage research studies our approach performs the latter attempt via nonparametric smoothing techniques rather than econometric methods such as ols or tobit related techniques results show that efficiency scores especially under the nonconvexity assumption fdh are higher for large municipalities thus there is empirical evidence to suggest that resources may be better allocated by large municipalities however the inefficiency found is not entirely attributable to poor management as second stage analysis reveals both fiscal and political variables to be explicably related to municipality performance moreover the explanatory variables impact on efficiency is robust to the chosen technique either convex dea or nonconvex fdh

china s changing energy intensity trend a decomposition analysis china experienced a dramatic decline in energy intensity from the onset of economic reform in the late 1970s until 2000 but since then the rate of decline slowed and energy intensity actually increased in 2003 most previous studies found that most of the decline was due to technological change but disagreed on the role of structural change to the best of our knowledge no decomposition study has investigated the role of inter fuel substitution in the decline in energy intensity or the causes of the rise in energy intensity since 2000 in this paper we use logarithmic mean divisia index lmdi techniques to decompose changes in energy intensity in the period 1980 2003 we find that 1 technological change is confirmed as the dominant contributor to the decline in energy intensity 2 structural change at the industry and sector sub industry level actually increased energy intensity over the period of 1980 2003 although the structural change at the industry level was very different in the 1980s and in the post 1990 period 3 structural change involving shifts of production between sub sectors however decreased overall energy intensity 4 the increase in energy intensity since 2000 is explained by negative technological progress 5 inter fuel substitution is found to contribute little to the changes in energy intensity

profit efficiency for spanish savings banks abstract frontier profit efficiency is examined for spanish savings banks over 1986 1991 a period in which the spanish banking has seen considerable deregulation in spain the standard assumption that firms operate in a perfectly competitive output market is unlikely to be met thus we use an alternative profit function specification which allows for market power in the output market profit efficiency is determined using the thick frontier approach and estimated using both alternative and standard profit function specifications to illustrate the effect of different assumptions regarding the competitiveness of the output market estimation of the alternative profit function suggests that the profit inefficiency of spanish savings banks which averaged 28 fell by forty percent between 1986 to 1991 the standard profit function which we believe yields less reliable results generated greater average inefficiency there was no significant shift up or down in the profit frontier itself

distribution of cost and profit efficiency evidence from indian banking this paper uses the nonparametric dea methodology to estimate cost and profit efficiency of indian banks during the post reform period the results show considerable variation in average levels of profit efficiency across various ownership categories of banks in general state owned banks are found to be more efficient than their private counter parts further efficiency tends to be low among the small banks assets up to rs 50 billion indicating that at the existing scale of operations these banks are operating far below the efficient frontier we also examine the distribution of efficiency using nonparametric kernel density estimates the analysis reveals a rightward shift of the efficiency distribution over the years a major part of this shift comes from the state owned banks based on the conditional distribution the study finds strong evidence of ownership explaining the efficiency differential of banks additionally bank size and product mix are also found to be important although to a lesser extent

the lmdi approach to decomposition analysis a practical guide in a recent study ang energy policy 32 2004 compared various index decomposition analysis methods and concluded that the logarithmic mean divisia index method is the preferred method since the literature on the method tends to be either too technical or specific for most potential users this paper provides a practical guide that includes the general formulation process summary tables for easy reference and examples

dynamic effects in inefficiency evidence from the colombian banking sector firms face a continuous process of technological and environmental changes that requires them to make managerial decisions in a dynamic context however costs and constraints prevent firms from making instant adjustments towards optimal conditions and may cause inefficiency to persist in time we propose a dynamic inefficiency specification that captures differences in the adjustment costs among firms and non persistent effects of inefficiency heterogeneity the model is fitted to a ten year sample of colombian banks the new specification improves model fit and have effects on efficiency estimations overall colombian banks present high inefficiency persistence but important differences between institutions are found in particular merged banks present low adjustment costs that allow them to recover rapidly efficiency losses derived from merging processes

technological change technological catch up and capital deepening relative contributions to growth and convergence we decompose labor productivity growth into components attributable to 1 technological change shifts in the world production frontier 2 technological catch up movements toward or away from the frontier and 3 capital accumulation movement along the frontier the world production frontier is constructed using deterministic methods requiring no specification of functional form for the technology nor any assumption about market structure or the absence of market imperfections we analyze the evolution of the cross country distribution of labor productivity in terms of the tripartite decomposition finding that technological change is decidedly nonneutral and that both growth and bipolar international divergence are driven primarily by capital deepening jel o30 o47 d24

economic reforms in india since 1991 has gradualism worked opinions on the causes of india s growth deceleration vary world economic growth was slower in the second half of the 1990s and that would have had some dampening effect but india s dependence on the world economy is not large enough for this to account for the slowdown critics of liberalization have blamed the slowdown on the effect of trade policy reforms on domestic industry however the opposite view is that the slowdown is due not to the effects of reforms but rather to the failure to implement the reforms effectively this in turn is often attributed to india s gradualist approach to reform which has meant a frustratingly slow pace of implementation however even a gradualist pace should be able to achieve significant policy changes over ten years this paper examines india s experience with gradualist reforms from this perspective

why did china s energy intensity increase during 1998 2006 decomposition and policy analysis abstract despite the fact that china s energy intensity has continuously decreased during the 1980s and mostly 1990s the decreasing trend has reversed since 1998 and the past few years have witnessed rapid increase in china s energy intensity we firstly conduct an index decomposition analysis to identify the key forces behind the increase it is found that 1 the high energy demand in industrial sectors is mainly attributed to expansion of production scale especially in energy intensive industries 2 energy saving mainly comes from efficiency improvement with energy intensive sectors making the largest contribution and 3 a heavier industrial structure also contributes to the increase this study also makes the first attempt to bridge the quantitative decomposition analysis with qualitative policy analyses and fill the gap between decomposition results and policy relevance in previous work we argue that 1 energy efficiency improvement in energy intensive sectors is mainly due to the industrial policies that have been implemented in the past few years 2 low energy prices have directly contributed to high industrial energy consumption and indirectly to the heavy industrial structure we provide policy suggestions in the end

bank productivity and performance groups a decomposition approach based upon the luenberger productivity indicator abstract the purpose of this paper is twofold first in the framework of the strategic groups literature it analyzes changes in productivity and efficiency of spanish private and savings banks over an eight year period 1998 2006 second by adapting the decomposition of the malmquist productivity indices suggested by fare et al 1994 it proposes similar components decomposing the luenberger productivity indicator initially productivity is decomposed into technological and efficiency changes thereafter this efficiency change is decomposed into pure efficiency scale and congestion changes empirical results demonstrate that productivity improvements are partially due to technological innovation furthermore it is shown how the competition between private and savings banks develops in terms of the analyzed productivity and efficiency components while private banks enjoy better efficiency change savings banks contribute more to technological progress consequently the luenberger components are used as cluster analysis inputs thus economic interpretations of the resulting performance groups are made via key differences in productivity components finally following the strategic groups literature supplementary insights are gained by linking these performance groups with banking ratios

economic consequences of deregulation evidence from the removal of voting cap in indian banks abstract we examine the effect of the 2005 banking regulation amendment bill and the 2011 banking laws amendment bill proposals for removal of the 10 percent voting rights cap in indian banks the 2011 banking laws bill was first introduced in 2005 but lapsed with the dissolution of the 14th lok sabha the bill was passed in december 2012 and raised the voting cap in private sector banks from 10 to 26 percent we present evidence that the removal of the voting cap enhances the value of votes of bank stocks by reducing the wedge between cash flow and control rights thus increasing monitoring and the probability of takeover post deregulation analysis reveals that the passage of the bill was followed by increasing blockholders number and percentage of shares held in larger and government banks furthermore a stronger negative relationship between banks profitability and size as well as share of non performing loans is observed this study makes an important contribution to the growing literature on the valuation impact and efficiency gains of liberalization of ownership restrictions in emerging markets as well as the rich literature on corporate governance and control relating to the value of voting privilege in companies with disparate voting rights

structural decompositions of energy consumption between 1995 and 2009 evidence from wiod abstract energy is key to achieving sustainable development this paper explicitly distinguishes between the supply side of energy consumption and demand side of energy consumption and investigates the factors that affect the energy consumption across economies using data from the world input output database wiod this paper decomposes the relative changes of energy consumption into intensity effect production structure structural change in final demand total final demand effect and household consumption then it further decomposes production structure into inter industry structural effect and trade effect in intermediate inputs overall energy consumption growth is mainly driven by total final demand 55 04 increase at the world level but can be significantly reduced by intensity effect due to technological change 21 02 decrease at the world level there is heterogeneity of structure related effects across economies and within the same economy in both aspects of energy consumption in addition the trade effect and household effect are relatively small this paper provides an empirical framework for analyzing energy consumption in a globalizing world and suggests tailored and integrated energy policies

regulation and development of the argentinean gas market gas markets are becoming increasingly important around the world and the long term evolution of these markets is of strategic importance for many countries this makes it essential to understand how regulation and intervention in these markets affects the long term prospect for the secure supply of gas we use argentina as a case to illustrate some of the issues and consequences of gas regulation argentina is a country that has had a significant increase in the use of gas over the years and where a potential gas deficit looms large in the present and the future based on a simulation model developed to understand the supply of gas in argentina we discuss how regulation will influence the long term supply of gas in both argentina and surrounding countries using the model we develop a series of scenarios to highlight the consequences of different current and possible future interventions in the market by the regulator finally we discuss short term regulatory options to reduce the impact of a gas deficit and the possibility of securing the long term supply of gas in argentina

factors shaping aggregate energy intensity trend for industry energy intensity versus product mix understanding the mechanisms of change of energy consumption in industry has attracted much attention since the 1973 world oil crisis a popular line of research has been to decompose changes in the aggregate energy intensity of industry to give the relative impacts arising from energy intensity change and product mix change using a decomposition technique many empirical studies covering a large number of countries have been reported the main objective of this paper is to put together the empirical results reported in these studies in a coherent framework and identify possible systematic features of particular interest are the basic trends in this line of research the relative importance of energy intensity change and product mix change possible variations over time and between country groups in the energy impacts of these changes and inconsistencies in findings among studies an overview of the decomposition technique including its strengths weaknesses and role in industrial energy consumption studies is also presented

determinants of bank efficiency the case of brazil abstract this paper analyzes the efficiency of the brazilian banking sector over the post privatization period of 2000 2007 we employ a bayesian stochastic frontier approach which provides exact efficiency estimates and confidence intervals and thus allows an accurate comparison across institutions and bank groups the results suggest that large banks are the most cost and profit efficient supporting the concentration process observed in recent years foreign banks have achieved a good performance through either the establishment of new affiliates and the acquisition of local banks the remaining public banks have had improvements in cost efficiency but are relatively profit inefficient finally we observe a positive impact of capitalization on efficiency

attribution of changes in divisia real energy intensity index an extension to index decomposition analysis abstract in this paper we extend the methodology of index decomposition analysis ida in energy studies by quantifying the contribution of individual attributes to the percent change of factors such as the real energy intensity index and structural change index we apply the proposed method to the real energy intensity index in the multiplicative logarithmic mean divisia index m lmdi approach a major ida technique since the m lmdi is based on geometric mean type indices and chain computation we need some appropriate method to cope with the difficulties that arise we present a numerical illustration of the proposed method using the energy consumption and real value added data of the us manufacturing industry and compare the results obtained by the fisher real energy intensity index

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

efficiency dynamics in indian banking a conditional directional distance approach abstract the paper contributes to the contemporary research on bank efficiency in india we analyze the efficiency dynamics of the indian banking industry from 2004 to 2012 based on the recent methodological developments of the conditional and unconditional directional distances introduced by daraio and simar 2014 we apply a conditional directional distance estimator in order to analyze the dynamic effects of industry s performance levels the results indicate that foreign banks perform better compared to national and domestic private banks there is also evidence of technological change at the period before the global financial crisis however during and after the global financial crisis these gains diminished the evidence suggests that national banks fail to sustain their high performance levels gained after the industry s restructuring period finally the findings support the view that ownership structure affects banks technical efficiency levels

economies of scale technical change and persistent and time varying cost efficiency in indian banking do ownership regulation and heterogeneity matter abstract banks with different ownership types adjust differently to changes in regulatory environments although this topic has been widely studied all the previous studies fail to control for bank heterogeneity bank specific effects in estimating cost structure and efficiency we propose a model where we control for bank heterogeneity and introduce persistent and time varying inefficiency additionally we incorporate determinants of both persistent and time varying inefficiency as well as production risks furthermore our model allows estimation of different technologies for different ownership types jointly we use this model to analyze the effect of regulation in indian banking we find that private banks have not exhausted their economies of scale foreign banks are operating under diseconomies of scale especially after the reforms and scale economies of state owned banks are unaffected by regulation banks of all ownership types have enjoyed technical progress however foreign banks have benefited the most followed by state owned banks only state banks were able to improve their cost efficiency while private banks and especially foreign banks were lagging behind their cost frontiers

the energy intensity in lithuania during 1995 2009 a lmdi approach abstract the measurement assessment and effective mitigation of energy intensity compose a foremost objective of contemporary energy policy although the european union eu member states have been experiencing the convergence in energy efficiency indicators lithuania acceded to the eu in 2004 still remains peculiar with relatively high energy intensity our study therefore is aimed at analyzing the energy intensity trends in lithuanian economy as a whole as well as in separate economic sectors the investigation covers the period of 1995 2009 the logarithmic mean divisia index was applied for decomposition analysis our analysis has shown that energy efficiency falls during economic downturn in order to facilitate these challenges the lithuanian government as well as business should opt for increasing energy efficiency in the most problematic sectors of transport and services in addition the analysis of legal acts namely national energy efficiency programme for 2006 2010 and energy efficiency action plan for 2010 2016 was taken into consideration some suggestions thus were offered for successful implementation of strategic goals outlined in the aforementioned strategic documents

energy intensity in the iron and steel industry a comparison of physical and economic indicators abstract energy consumption of the iron and steel industry is examined in seven countries brazil china france germany japan poland and the united states for the period 1980 1991 using a decomposition analysis based on physical indicators for process type and product mix we decompose intra sectoral structural changes and efficiency improvements specific energy consumption decreased in all countries except poland efficiency improvement played a key role in brazil china germany and the us while structural changes were the main driver for energy savings in france and japan we also compare the use of various economic indicators to physical indicators and find that they do not track physical developments well in poland or the developing countries we studied in the industrialized countries value added based energy intensity indicators generally reflect the specific energy consumption better than other economic indicators although large differences occur in individual years we found a smaller correlation between other economic indicators gross output and value of shipments and specific energy consumption we conclude that use of physical energy intensity indicators improves comparability between countries provides greater information for policy makers regarding intra sectoral structural changes and provides detailed explanations for observed changes in energy intensity

how does the implementation of the policy of electricity substitution influence green economic growth in china abstract to promote the level of electrification reduce environmental pollution and achieve the goal of clean energy usage and green economic growth in china the national development and reform commission and other eight departments jointly issued and implemented the policy of electricity substitution in 2016 electricity substitution aims to replace traditional fossil fuels such as coal and fuel oil with clean electric energy in different fields e g industry transportation and construction and deal with the pollutants at power generation however we still need to find out the exact impact of the policy of electricity substitution on energy saving and emission reduction in this paper we estimate the economically feasible increment of electricity demand according to different classifications in electricity substitution technology furthermore based on the input output model we discuss the relative influence of the policy of lectricity substitution the main conclusions are first the policy of electricity substitution alone is not adequate to reduce the dependence on fossil energy and environmental pollution under china s current power generation structure we should also increase the use of renewable energy second the power sector plays a leading role in stimulating economic output and the increasing electricity consumption due to the policy of electricity substitution can boost the green development of china s economy

analysis and decomposition of energy consumption in the chilean industry abstract with rising energy costs and climate change concerns energy efficiency will be important in maintaining competitiveness and reducing the environmental impact of industrial activities in this paper we study the chilean industrial sector which is the largest consumer of energy within the country energy demand and co 2 emissions in chile have grown rapidly in recent years while energy supply is mostly imported and subject to disruption therefore it is important to understand energy consumption in this sector and determine which sub sectors have the greatest potential to reduce energy consumption we used the index decomposition analysis ida applying the logarithmic mean divisia index method i lmdi i to quantify the impact of diverse driving factors on energy consumption furthermore a panel data analysis was used to determine whether there are differences in energy intensity across firms with different characteristics our results show that energy intensity has risen over time although energy consumption remains stable this fact supports the idea that energy efficiency policies could play an important role for the industrial sector additionally energy consumption and energy intensity follow different patterns in each sub sector therefore we conclude that the application of differentiated sectoral policies is preferable over a single global policy

financial sector liberalization bank privatization and efficiency evidence from pakistan abstract the pakistani banking system has been transformed over the past 15 years through liberalization the entry of private banks the privatization of public sector banks and the tightening of prudential regulations the effects of these changes on bank productivity and relative efficiency are investigated using various techniques bank productivity in terms of profits has increased and new entrants have been efficient but the dispersion of efficiency remains wide the privatized banks improved their profit efficiency in the period immediately following their privatization but in the subsequent years only one significantly improved its efficiency whereas the other did not differentiate itself in terms of efficiency from the remaining state owned banks the new private domestic banks generally proved to be among the most efficient and sometimes out performed the foreign banks

an alternative conditioning scheme to explain efficiency differentials in banking abstract we investigate whether specialization ownership type or size bias bank efficiency the approach we apply focusing on the entire distributions of efficiency scores sheds light on the firms precise relative positions when controlling for these firms characteristics results suggest that conclusions related to this topic should consider these techniques given efficiency scores generated by nonparametric techniques are clearly dependent on each other in the statistical sense

deregulation ownership and productivity growth in the banking industry evidence from india this paper analyzes the relationship between deregulation and total factor productivity tfp growth in the indian banking industry using a generalized shadow cost function approach tfp growth is decomposed into a technological change a scale and a miscellaneous component a disaggregated panel data analysis using the population of public and private banks over 1985 96 that covers both pre and post deregulation periods indicates that a significant decline in regulatory distortions and the anticipated increase in tfp growth have not yet materialized following deregulation while private sector banks have improved their performance mainly due to the freedom to expand output public sector banks have not responded well to the deregulation measures

how can chile move away from a high carbon economy abstract this paper quantitatively evaluates the performance of chile s co2 emissions between 1991 and 2013 using a complete decomposition technique to examine emissions and their components a decomposition analysis based on log mean divisia index method lmdi i was conducted six decomposition factors were considered carbon intensity effect ci res penetration effect res energy intensity effect ei economy structure effect es income effect yp and population effect p to know how these factors could influence each other in the future the innovative accounting approach iaa was used including forecast error variance decomposition and impulse response functions irfs these two methodologies allow us to identify the drivers of co2 emission changes in the past 1991 2013 test policy measures and learn how these drivers could influence each other in the future to evaluate whether the current measures meet the paris commitments the lmdi analysis results show that the energy intensity factor is the main compensating factor of chile s co2 emissions and the only effect with a clear trend to aid the economy s decoupling iaa and ifrs results react similarly and confirm that carbon intensity reacts to shocks more significantly in the short term the reaction to res has the same and opposite behavior to shocks in es and yp to disappear in the long term

predicting bank performance with financial forecasts a case of taiwan commercial banks abstract data envelopment analysis dea has been used as a tool for evaluating past accomplishments in the banking industry however due to a time lag the results usually arrive too late for the evaluated banking institutions to react timely this paper makes advanced predictions of the performances of 24 commercial banks in taiwan based on their financial forecasts the forecasts based on uncertain financial data are represented in ranges instead of as single values a dea model for interval data is formulated to predict the efficiency the predictions of the efficiency scores are also presented as ranges we found that all the efficiency scores calculated from the data contained in the financial statements published afterwards fall within the corresponding predicted ranges of the efficiency scores which we had calculated from the financial forecasts the results also show that even the bad performances of the two banks taken over by the financial restructuring fund of taiwan could actually be predicted in advance using this study

towards a sustainable growth in latin america a multiregional spatial decomposition analysis of the driving forces behind co2 emissions changes abstract this paper aims to understand the driving forces behind the growth of co2 emissions in latin america as a region by groups of countries according to their behaviour in terms of growth of income and co2 emissions per capita and by countries during 1990 2013 the main drivers for the latin america region are the activity and the population effects followed by the fossil fuel and the carbonisation effects while the intensity effect is revealed as the only inhibitor the lessons from latin america s group of countries are the following first the necessary decoupling between the growth of co2 emissions and the economic activity has not taken place the population growth also being an important driver effect second the groups of countries with the highest co2 emissions growth show the highest population and fossil fuel effects this latter confirms the scant efforts made to reduce the weight of fossil fuels in the total primary energy supply third the energy intensity has become the most important inhibitor of co2 emissions for those countries that are not able to substitute fossil fuels so easily finally the desirable increase of less pollutant fossil fuels or even the increase of renewable energies has not yet been achieved
