oil price cycles and wavelets abstract the present paper addresses the question of the oil price macroeconomy relationship using world data and a time scale decomposition based on the theory of wavelets our approach is based on a global indicator the morgan stanley capital international msci index for the world and on the new framework offered by wavelets to analyse the oil price cycles and to investigate the oil price msci relationship this original approach enables us to identify that the cycles which contribute the most to oil price variations are 20 to 40 years cycles which correspond to the size of kuznets infrastructure cycles and probably represent energy investment cycles this wavelet decomposition also provides additional evidence to the reverse causality theory

co2 emissions energy consumption economic growth and financial development in gcc countries dynamic simultaneous equation models abstract this study investigates the dynamic causal relationships among carbon emissions financial development economic growth and energy consumption for gulf cooperation council gcc countries from 1980 through 2011 annual time series data and an autoregressive distributed lag ardl model are used the main contribution of this paper is that it has investigated the causes of carbon emissions by taking into account the role of financial development and economic growth in gcc countries the results suggest long run and causal relationships among carbon emissions financial development gross domestic product gdp and energy use in all gcc countries except united arab emirates uae moreover there is long run unidirectional causality running from carbon emissions to energy use in the case of saudi arabia uae and qatar furthermore a one way causal relationship from financial development to carbon emissions in the context of uae oman and kuwait is found the evidence suggests that financial systems should take into account environmental aspects in their current operations in these countries the results of this study may be of great importance for policy and decision makers in developing energy policies for gcc countries that contribute to curbing carbon emissions while preserving economic growth

determinants of energy productivity in 39 countries an empirical investigation abstract this paper uses three types of analysis to investigate the drivers of energy productivity changes occurring in 39 countries during 1995 2009 we find that increases in sectoral energy productivity were the primary driver behind economy wide energy productivity improvements structural economic shifts away from industry and towards service oriented sectors played a lesser role in aggregate energy productivity improvements nations with similar demographic and economic characteristics showed similar levels of energy productivity and rates of improvement most notably former communist countries and nations undergoing economic liberalization exhibited the highest rate of improvement although they are still less energy productive than developed nations moreover the econometric analysis reinforces the long standing hypothesis that higher levels of income per capita and higher energy prices are associated with greater energy productivity while a greater share of output from industry is associated with lower energy productivity levels in particular higher energy prices and income levels are associated with improvements in sectoral energy productivity

valuing the attributes of renewable energy investments increasing the proportion of power derived from renewable energy sources is becoming an increasingly important part of many countries s strategies to achieve reductions in greenhouse gas emissions however renewable energy investments can often have external costs and benefits which need to be taken into account if socially optimal investments are to be made this paper attempts to estimate the magnitude of these external costs and benefits for the case of renewable technologies in scotland a country which has set particularly ambitious targets for expanding renewable energy the external effects we consider are those on landscape quality wildlife and air quality we also consider the welfare implications of different investment strategies for employment and electricity prices the methodology used to do this is the choice experiment technique renewable technologies considered include hydro on shore and off shore wind power and biomass welfare changes for different combinations of impacts associated with different investment strategies are estimated we also test for differences in preferences towards these impacts between urban and rural communities and between high and low income households

decomposition analysis of co2 emission intensity between oil producing and non oil producing sub saharan african countries abstract the need to decompose co2 emission intensity is predicated upon the need for effective climate change mitigation and adaptation policies such analysis enables key variables that instigate co2 emission intensity to be identified while at the same time providing opportunities to verify the mitigation and adaptation capacities of countries however most co2 decomposition analysis has been conducted for the developed economies and little attention has been paid to sub saharan africa the need for such an analysis for ssa is overwhelming for several reasons firstly the region is amongst the most vulnerable to climate change secondly there are disparities in the amount and composition of energy consumption and the levels of economic growth and development in the region thus a decomposition analysis of co2 emission intensity for ssa affords the opportunity to identify key influencing variables and to see how they compare among countries in the region also attempts have been made to distinguish between oil and non oil producing ssa countries to this effect a comparative static analysis of co2 emission intensity for oil producing and non oil producing ssa countries for the periods 1971 1998 has been undertaken using the refined laspeyres decomposition model our analysis confirms the findings for other regions that co2 emission intensity is attributable to energy consumption intensity co2 emission coefficient of energy types and economic structure particularly co2 emission coefficient of energy use was found to exercise the most influence on co2 emission intensity for both oil and non oil producing sub saharan african countries in the first sub interval period of our investigation from 1971 1981 in the second subinterval of 1981 1991 energy intensity and structural effect were the two major influencing factors on emission intensity for the two groups of countries however energy intensity effect had the most pronounced impact on co2 emission intensity in non oil producing sub saharan african countries while the structural effect explained most of the increase in co2 emission intensity among the oil producing countries finally for the period 1991 1998 structural effect accounted for much of the decrease in intensity among non oil producers while co2 emission coefficient of energy use was the major force driving the decrease among oil producing countries the dynamic changes in the co2 emission intensity and energy intensity effects for the two groups of countries suggest that fuel switching had been predominantly towards more carbon intensive production in oil producing countries and less carbon intensive production in non oil producing ssa countries in addition to the decomposition analysis the article discusses policy implications of the results we hope that the information and analyses provided here would help inform national energy and climate policy makers in ssa of the relative weaknesses and possible areas of strategic emphasis in their planning processes for mitigating the effects of climate change

the nexus between financial development and energy consumption in the eu a dynamic panel data analysis abstract the relationship between financial development and energy consumption has newly started to be discussed in energy economics literature this paper investigates this issue in the eu over the period 1990 2011 by using system gmm model no significant relationship is found in the eu27 the empirical results however provide strong evidence of the impact of the financial development on energy consumption in the old members greater financial development leads to an increase in energy consumption regardless of whether financial development stems from banking sector or stock market by contrast we find for the new members that the impact of financial development on energy consumption depends on how financial development is measured using bankindex the impact of financial development displays an inverted u shaped pattern while no significant relationship is detected once it is measured using stockindex

testing for non response and sample selection bias in contingent valuation analysis of a combination phone mail survey we use a combination phone mail survey to test for possible sample biases in contingent valuation we find no sample selection bias but do find non response bias we show how failure to correct for non response bias distorts aggregate benefit estimates

obtaining welfare bounds in discrete response valuation studies comment in a recent article published in land economics boman bostedt and kristrim 1999 hereafter bbk show how nonparametric lower bound intermediate and upper bound measures of average welfare change can be extracted from discrete response contingent valuation survey data building on the work of kristrim 1990 and haab and mcconnell 1997 the article appears to offer a promising route to getting estimates of mean willingness to pay wtp along with their respective variances without having to estimate parametric choice models thereby providing a computationally simple way to capture both the methodological uncertainty about the choice of a central tendency measure and the statistical uncertainty associated with any particular measure having an accurate estimate of the variance of mean wtp allows one to make confidence interval statements about mean wtp when measures of mean wtp and its variance are extracted

factors that influence carbon emissions due to energy consumption based on different stages and sectors in china abstract this study analyzes carbon emissions due to energy consumption based on different stages and sectors in china and by applying the logarithmic mean divisia index decomposition method carbon emissions were decomposed into energy structure energy intensity economic structure and economic output effects the study period was divided into high efficiency and high output low efficiency and low output high efficiency and low output and low efficiency and high output considering different carbon emission characteristics and economic development carbon emissions exhibit different characteristics at different stages the degree of increase in carbon emissions at these stages depends on the combined effect of the energy efficiency and the economic output the main factor driving carbon emissions was the economic output effect in each stage and the main factor inhibiting carbon emissions was the energy intensity effect the economic and energy structures had only a modest effect on carbon emissions at each stage the industry sector was the top contributor to carbon emissions followed by the transport sector the policy implications in terms of economic growth the economic structure and energy consumption are discussed in relation to the different stages

how much is too much an investigation of the effect of the number of choice sets context dependence and the choice of bid vectors in choice experiments in a split sample design we examine how the number of choice sets design of the first choice set context dependence and the choice of attribute levels in the cost attribute affect the precision in the elicited preferences in otherwise completely identical choice experiment surveys these issues are investigated for swedish households marginal willingness to pay to reduce power outages our results indicate that neither the number of choice sets nor the design of the first choice set has a significant impact on estimated marginal willingness to pay while the effect was significant for the additive scaling of the cost vector at the end of the article we discuss the implications of our results on future developments and applications of choice experiments

electricity outages in ghana are contingent valuation estimates valid african countries experience persistent and serious energy outages but while multiple valuation studies provide estimates of the costs of electricity outages in high income countries evidence is scarce for lower and middle income countries the few studies that assess the value of reliable energy supply rely on the contingent valuation method that is under wide scrutiny this paper aims to provide new estimates of households willingness to pay to reduce electricity outages for ghana and contributes to the debate on the validity of contingent valuation results for energy reliability our results suggest that households are willing to pay ghs 67 17 per month for reliable electricity supply equivalent to 7 of respondents income the results of tests for hypothetical bias wtp wta disparity and income effects suggest that the contingent valuation estimates from this study are robust and can support decision makers in prioritizing energy policies and investments

the contribution of energy use and financial development by source in climate change mitigation process a global empirical perspective abstract the danger of climate change has over the years become a reality in the public domain while efforts to mitigate climate change involve energy mix energy efficiency and cleaner technology financial development has also been considered as an important factor indicator of financial development may draw fdi and advanced degree of research and development which can accelerate economic growth and hence affect dynamism of environmental performance this study examines the impacts of energy use and financial development indicators by source in the environment growth energy model for 90 countries categorized on the basis of income possession over the period 1980 2014 the study applies the panel analysis that accounts for cross sectional dependence and heterogeneity of series used in the estimation results from panel dynamic ordinary least squares dols show that in all the categories of countries fossil fuel energy use and gdp per capita are found to be the major drivers of co2 emissions though fossil fuel energy use possesses the bigger elasticities population however displays a sign contrary to expectation regarding economic theory in high income countries renewable energy and financial development on the other hand are capable of reducing co2 emissions however the magnitude of the long run elasticity of co2 emissions with respect to renewable energy use and financial development are much greater in the models with m2 gdp than the model with m2 reserve especially in the high income countries policies should be geared towards stimulating investments in renewable energy technology there is need to develop robust financial systems to lend financial credence to research institutes to work towards producing energy that have less carbon or are carbon free

measuring the demand for improved urban sanitation services results of a contingent valuation study in ouagadougou burkina faso in developing countries there are few institutional mechanisms for the incorporation of demand information in the planning of public services as a result misjudgements about consumer preferences have often led to poor project design and performance the contingent valuation method which relies on direct elicitation of consumer preferences and willingness to pay has emerged as one approach to address this shortcoming the paper describes an application of the method to facilitate demand driven planning for provision of improved sanitation in ouagadougou burkina faso the results suggest that demand information about unfamiliar technologies can be successfully obtained and can serve as a useful input in the design of public services

does oil move equity prices a global view many studies indicate that oil price shocks have an adverse effect on real output and hence an adverse effect on corporate profits where oil is used as a key input the present study examines whether and to what extent the adverse effect of oil price shocks impacts stock market returns to this end we analyse 35 datastream global industry indices for the period from april 1983 to september 2005 our findings indicate that oil price rises have a negative impact on equity returns for all sectors except mining and oil and gas industries generally these results are consistent with economic theory and evidence provided by previous empirical studies little evidence of any asymmetry is detected in the oil price sensitivities in light of our findings we recommend that international portfolio investors consider hedging oil price risk

on the nexus of financial development economic growth and energy consumption in china new perspective from a gmm panel var approach abstract this paper studies the endogenous relationships among financial development energy consumption and economic growth in china by applying a gmm panel var approach with a panel data of 30 chinese provinces over the period 1996q1 2015q4 financial development is measured by six individual indicators and by a comprehensive indicator obtained through the pca method we also account for regional heterogeneity by dividing our sample into three regions eastern region central region and western region we underline our findings in three aspects first financial development measured by most individual indicators m2 credit revenue of the insurance industry and stock market value and the comprehensive one has a significantly negative impact on economic growth second energy consumption can significantly contribute to economic growth in all regions while no feedback effect is found except in the western region this result is further supported by the granger causality tests last financial development in the sense of m2 credit stock turnover and the comprehensive indicator can significantly lessen energy consumption in all regions but this inhibitory effect is found to be largest in the western region followed by the eastern region and be smallest in the central region the granger causality tests confirm further the existence of heterogeneity across regions a bidirectional granger causality between the two variables is found in the eastern region a unidirectional granger causality running from energy consumption to financial development is identified in the central region and no significant causal relationship shows up in the western region our findings provide valuable policy implications for china heading for a green economic growth

volatility spillovers between oil prices and stock sector returns implications for portfolio management abstract in this article we take a recent generalized var garch approach to examine the extent of volatility transmission between oil and stock markets in europe and the united states at the sector level the empirical model is advantageous in that it typically allows simultaneous shock transmission in the conditional returns and volatilities insofar as volatility transmission across oil and stock sector markets is a crucial element for portfolio designs and risk management we also analyze the optimal weights and hedge ratios for oil stock portfolio holdings with respect to the results our findings point to the existence of significant volatility spillover between oil and sector stock returns however the spillover is usually unidirectional from oil markets to stock markets in europe but bidirectional in the united states our back testing procedures finally suggest that taking the cross market volatility spillovers estimated from the var garch models often leads to diversification benefits and hedging effectiveness better than those of commonly used multivariate volatility models such as the ccc garch of bollerslev 1990 the diagonal bekk garch of engle and kroner 1995 and the dcc garch of engle 2002

choice experiment study on the willingness to pay to improve electricity services abstract modern forms of energy are an important vehicle towards poverty alleviation in rural areas of developing countries most developing countries households rely heavily on wood fuel which impacts on their health and socio economic status to ease such a dependency other modern forms of energy namely electricity need to be provided however the quality of the electricity service namely reliability is an important factor in reducing this dependency this paper discusses a choice experiment valuation study conducted among electrified rural households located in kisumu kenya in which the willingness to pay wtp to avoid power outages or blackouts was estimated a mixed logit estimation was applied to identify the various socio economic and demographic characteristics which determine preferences in reducing power outages among a household s users in conclusion several of the socio economic and demographic characteristics outlined in this paper were identified and can assist service differentiation to accommodate the diverse households preferences towards the improvement of the electricity service

regime switching effect of financial development on energy intensity evidence from markov switching vector error correction model abstract studies that deal with financial development and energy intensity usually show the single effect of one variable on another or the causality running between them during the whole sample period but this study is an attempt to explore the regime switching effect of financial development on energy intensity in different periods within the sample using yearly data from 1972 to 2017 in case of bangladesh a markov switching vector error correction model is applied to carry out the study and the results reveal a two regime switching nature of the effect of financial development on energy intensity financial development plays a stimulating role in regime 1 where it plays an inhibiting role in regime 2 to influence energy intensity the duration of regime 1 is longer than that of regime 2 specifying that the promoting effect of financial development on energy intensity is more enduring than the inhibiting effect in bangladesh the results have important policy implications to formulate energy policy and to maintain a balance between financial development and energy intensity in bangladesh and other emerging nations

does financial development increase energy consumption the role of industrialization and urbanization in tunisia this paper assesses the relationship among energy consumption financial development economic growth industrialization and urbanization in tunisia from 1971 to 2008 the autoregressive distributed lag bounds testing approach to cointegration and granger causality tests is employed for the analysis the result confirms the existence of long run relationship among energy consumption economic growth financial development industrialization and urbanization in tunisia long run bidirectional causalities are found between financial development and energy consumption financial development and industrialization and industrialization and energy consumption hence sound and developed financial system that can attract investors boost the stock market and improve the efficiency of economic activities should be encouraged in the country nevertheless promoting industrialization and urbanization can never be left out from the process of development we add light to policy makers with the role of financial development industrialization and urbanization in the process of economic development

financial development and energy consumption is the mena region different abstract this paper examines the relationship between financial development and energy consumption estimations in the major mena countries algeria bahrain egypt iran iraq israel jordan kuwait lebanon libya morocco oman qatar saudi arabia syria tunisia united arab emirates and yemen over the period 1996 to 2014 we consider the energy use in kg of oil equivalent per capita as a dependent variable that reflects the cross country energy consumption we measure the level of financial development in the mena countries by considering banking indicators extending the model of sadorsky 2011 we estimate both linear and non linear dynamic panel model we use new robust econometrics to take into account heterogeneity and nonlinearity and we control the estimation results for the period of the global financial crisis the results of the study report a positive and statistically significant relationship between the intermediation capacity of the banking system as well as its size and energy consumption the findings also confirm a non linear and inverted u shaped relationship between financial development and energy demand for the mena region this implies that initially energy demand increases with financial development and then at a turning point of financial development it declines the policy implications of these results are discussed

wavelet dynamics for oil stock world interactions abstract a previous research ignores the distinction between short term and long term and by decomposing financial variables world general and stock market indexes and the macroeconomic variable oil prices at various time scales we study the relationship among series on a daily scale by scale basis continuous time wavelets help to circumvent the problems associated to basic linear regressions and given that stock oil relationships are usually described as complicated we extend previous findings by providing more generalized and convincing results in analyzing contagion and interdependence issues as well as lead and lag effects for both world general and sector stock levels between december 1992 and october 2012 the relationship between oil prices and sector stock returns is ambiguous because results seem to show that there are both phase and anti phase relationships where mostly it is oil that is the lagging variable independently of the sector under analysis there is higher coherence among series for higher scales thus supporting the interdependence hypothesis showing that long run market dynamics are more uncertain empirical results indicate a bidirectional relationship between both series for large time horizons which can be associated to fundamentalist traders especially fund managers and institutional investors and which depend on the historical period under analysis

optimal electricity supply reliability using customer shortage costs abstract this paper describes an economic cost benefit method for determining the optimal power system capacity and reliability of electricity supply using customer shortage costs the approach is based upon identifying a system plan that simultaneously considers cost of service as well as value of service and maximizes the net economic benefits taking into account the interdependence between electricity reliability price and demand in contrast to the existing literature on this subject which considers only customer outage costs this paper argues that it is the related but considerably broader notion of customer shortage cost that is more relevant in the context of optimizing the reliability of electricity supply the paper develops a method for estimating shortage costs and sketches an integrated framework for optimizing reliability using such costs

time varying volatility spillover between chinese fuel oil and stock index futures markets based on a dcc garch model with a semi nonparametric approach abstract this paper reveals some new evidence on the volatility spillover between fuel oil and stock index futures markets in china by considering its time variant feature time varying effect is specified by the legendre polynomials in a dcc garch model moreover the semi nonparametric snp approach accounting for marginal excess kurtosis and asymmetry is applied we find different time evolving patterns of volatility spillover across multiple periods due to the structural breaks the direction of mean volatility spillover is found to be bilateral moreover the strength of mean volatility spillover shows that the effect from stock index to fuel oil futures is much stronger than the other way around this implies that the stock index futures market plays a leading role in information processing these findings have important implications for the fuel oil stakeholders as well as risk management

does financial agglomeration promote the increase of energy efficiency in china abstract whether financial agglomeration is conducive to the improvement of energy efficiency is of great significance for china to better follow the path of energy conservation and emission reduction and green sustainable development based on the balanced panel data of 285 cities in china from 2005 to 2017 this paper analyzes the impact of financial agglomeration on energy efficiency theoretical analysis shows that financial agglomeration can influence energy efficiency through scale economy effect innovation driving effect information spillover effect and structural adjustment effect dynamic spatial econometric results show that from a national perspective financial agglomeration has a positive impact on energy efficiency however from the perspective of different regions and different city sizes it is found that financial agglomeration can have different effects on energy efficiency financial agglomeration has a significant positive impact on energy efficiency in eastern and central regions megacities and big cities financial agglomeration has a significant negative impact on energy efficiency in western china and has no significant effect on energy efficiency in medium sized and small cities finally based on the conclusions of the study specific proposals for financial agglomeration to improve energy efficiency are proposed

how does financial development affect energy consumption evidence from 21 transitional countries abstract financial development significantly impacts energy consumption this paper uses cross country panel data from 21 transitional countries for the period 2006 2015 while considering different financial development indicators and nonlinear relationships between financial development and energy consumption this is done by selecting five financial development indicators to measure financial development and testing linear and nonlinear relationships between financial development and energy consumption it found the following first there are no significant linear relationships between financial development and energy consumption financial development does have significant nonlinear impacts on energy consumption in transitional countries with estimated nonlinear parameters that are significant second financial development affects energy consumption in transitional countries in differing ways financial intermediation development positively affected energy consumption in all the countries studied stock markets development led decreased energy consumption in china and poland financial openness development reduced energy use except in georgia and the kygyz republic

structural change and energy efficiency in industry the change in the ratio of energy consumed to industrial production is examined over the years 1968 1980 changes in the composition of industry are analysed creating a better picture of movements in physical efficiency of energy use the medium term trends show the significance of the 1973 oil crisis the effects being contrary to those of intuition the implications of the two recessions for efficiency and industrial structure are described in detail the role of demand often relegated to an incidental consideration is brought to the fore in the years following 1973 it appears more important than ex post substitution in production and with this comes a particular implication for the use of aggregate production functions

the impact of growth energy and financial development on the environment in china a cointegration analysis this article aims to investigate the impact of financial development economic growth and energy consumption on environmental pollution in china from 1953 to 2006 using the autoregressive distributed lag ardl bounds testing procedure the main objective is to examine the long run equilibrium relationship between financial development and environmental pollution the results of the analysis reveal a negative sign for the coefficient of financial development suggesting that financial development in china has not taken place at the expense of environmental pollution on the contrary it is found that financial development has led to a decrease in environmental pollution it is concluded that carbon emissions are mainly determined by income energy consumption and trade openness in the long run moreover the findings confirm the existence of an environmental kuznets curve in the case of china

the impact of financial development on carbon emissions an empirical analysis in china given the complexity between china s financial development and carbon emissions this paper uses some econometric techniques including cointegration theory granger causality test variance decomposition etc to explore the influence of financial development on carbon emissions results indicate that first china s financial development acts as an important driver for carbon emissions increase which should be taken into account when carbon emissions demand is projected second the influence of financial intermediation scale on carbon emissions outweighs that of other financial development indicators but its efficiency s influence appears by far weaker although it may cause the change of carbon emissions statistically third china s stock market scale has relatively larger influence on carbon emissions but the influence of its efficiency is very limited this to some extent reflects the relatively lower liquidity in china s stock markets finally among financial development indicators china s fdi exerts the least influence on the change of carbon emissions due to its relatively smaller volume compared with gdp but it is mainly utilized in carbon intensive sectors now therefore with the increase of china s fdi in the future many efforts should be made to adapt its utilizing directions and play its positive role in promoting low carbon development

a canadian customer survey to assess power system reliability worth a common approach used in quantifying the worth or benefit of electric service reliability is to estimate the customer costs monetary losses associated with power interruptions customer surveys are often used to determine interruption costs the ieee power systems research group has conducted surveys of canadian electric utility customers in the residential commercial and industrial sectors these surveys were sponsored by the natural sciences and engineering research council and seven participating utilities this paper presents the overall results of these surveys with emphasis on the cost results

are we willing to pay enough to back the bid valuing the intangible impacts of london s bid to host the 2012 summer olympic games using a contingent valuation survey this paper provides the first empirical test of the proposition that intangible impacts might justify hosting major sporting events on cost benefit grounds respondents drawn from london manchester and glasgow were asked for their willingness to pay wtp to host the 2012 olympic games in london on the basis of the intangible impacts that this event might provide annual mean wtp is 22 12 and 11 per year for 10 years in these 3 uk cities respectively an illustrative total uk wtp for intangible impacts is in the region of 2 billion statistical analysis of wtp determinants reveals a range of plausible explanatory factors such as respondents degree of support for the bid

an application of total factor energy efficiency under the metafrontier framework abstract as the computation of total factor energy efficiency tfee is not workable under the metafrontier framework since the metafrontier cannot fully envelope each group frontier this research provides a new computation mode to solve this problem following a discussion on the methodology we conduct empirical analysis on 28 member countries in the european union eu and then divide them into baltic sea region bsr countries and non baltic sea region nbsr countries for metafrontier analysis thus contributing to the literature by presenting an available mode for tfee analysis under the metafrontier framework the suggested mode herein operates so successfully that all computation scores exhibit a reasonable scope in addition the bsr s average energy efficiency performs better than nbsr s but the latter is still a technology exporter compared to the former this paper summarizes the conditions for sustainable energy development i set more serious energy efficiency targets ii reduce primary and final energy consumptions lower energy dependence on energy imports and increase the share of renewable energy sources to fossil fuel energy sources iii achieve a liberalized energy market and iv set reasonable energy prices by levying an energy tax in order to realize effective energy consumption

multilevel lmdi decomposition of changes in aggregate energy consumption a cross country analysis in the eu 27 abstract this paper aims at analysing the factors behind the change in aggregate energy consumption in the eu 27 also identifying differences between member states the logarithmic mean divisia index method lmdi is applied to multiplicatively decompose at the country level the variation in aggregate energy consumption in the eu 27 member states for the 2001 2008 period we also analyse the sensitivity of the results when several aggregation levels are considered with energy intensity used as the criterion to aggregate countries this allows us to check robustness of results also enabling an improved understanding of both inter and intra unit effects results indicate that improvements in energy efficiency in the eu 27 were not enough to overcome the pressure of european economic activity on aggregate energy consumption mediterranean countries and especially former communist states increased their energy consumptions most of them favoured by structural change the analysis also reveals that the impact of intra group movements on aggregate energy consumption is partially offset when moving from higher to lower aggregation levels

wavelet based test of co movement and causality between oil and renewable energy stock prices abstract we studied co movement and causality between oil and renewable energy stock prices using continuous and discrete wavelets firstly to obtain information on dynamic correlations over time and for different time scales from wavelet coherence and secondly to obtain information on linear and non linear granger causality in the time frequency domain for general and sectoral renewable energy indices for the period 2006 2015 our findings indicate that dependence between oil and renewable energy returns in the short run was weak but gradually strengthened towards the long run mainly for the period 2008 2012 our causality tests provide evidence against linear causality at higher frequencies and in favour of unidirectional and bidirectional linear causality at lower frequencies in contrast we found consistent evidence of non linear causality running from renewable energy indices to oil prices at different time horizons and mixed evidence of causality running from oil to renewable energy prices these results have potential implications for investors in terms of hedging and for policymakers in terms of policy support decisions regarding the development of renewable energy

economic costs of electricity supply interruptions us and foreign experience abstract this paper investigates the costs of interruptions in electricity service to customers this information is a key input in planning power system reliability using an economic cost benefit approach the paper reviews the literature from the perspective of identifying alternate methodological approaches used their strengths and weaknesses and potential for bias it presents and compares outage cost estimates found in the literature on a common denominator basis it attempts to explain the sources of the wide range of variation observed in different study estimates and it identifies the need for further work on this important topic

oil price shocks and stock markets in the u s and 13 european countries abstract oil price shocks have a statistically significant impact on real stock returns contemporaneously and or within the following month in the u s and 13 european countries over 1986 1 2005 12 norway as an oil exporter shows a statistically significantly positive response of real stock returns to an oil price increase the median result from variance decomposition analysis is that oil price shocks account for a statistically significant 6 of the volatility in real stock returns for many european countries but not for the u s increased volatility of oil prices significantly depresses real stock returns the contribution of oil price shocks to variability in real stock returns in the u s and most other countries is greater than that of interest rate an increase in real oil price is associated with a significant increase in the short term interest rate in the u s and eight out of 13 european countries within one or two months counter to findings for the u s and for norway there is little evidence of asymmetric effects on real stock returns of positive and negative oil price shocks for oil importing european countries

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

financial development growth and the distribution of income a paradigm is presented in which both the extent of financial intermediation and the rate of economic growth are endogenously determined financial intermediation promotes growth because it allows a higher rate of return to be earned on capital and growth in turn provides the means to implement costly financial structures thus financial intermediation and economic growth are inextricably linked in accord with the goldsmith mckinnon shaw view on economic development the model also generates a development cycle reminiscent of the kuznet hypothesis in particular in the transition from a primitive slow growing economy to a developed fast growing one a nation passes through a stage in which the distribution of wealth across the rich and poor widens

wavelet decomposition and regime shifts assessing the effects of crude oil shocks on stock market returns while there is a large body of empirical studies on the relationship between crude oil price changes and stock market returns they have failed to achieve a consensus on this subject in this paper we combine wavelet analysis and markov switching vector autoregressive ms var approach to explore the impact of the crude oil co shocks on the stock market returns for uk france and japan over the period from january 1989 to december 2007 our procedure involves the estimation of the extended ms var model in order to investigate the importance of the resultant wavelet filtering series after removing random components in determining the behavior of the stock market volatilities we show that co shocks do not affect the recession stock market phases except for japan however they significantly reduce moderate and or expansion stock market phases temporarily moreover this negative relationship appears to be more pronounced during the pre 1999 period the empirical findings will prove extremely useful to investors who need to understand the exact effect of international oil changes on certain stocks prices as well as for policy managers who need a more thorough evaluation about the efficiency of hedging policies affected by oil price changes

does it matter when a power outage occurs a choice experiment study on the willingness to pay to avoid power outages using a choice experiment survey the marginal willingness to pay wtp among swedish households for reductions in power outages is estimated the results from the random parameter logit estimation indicate that the marginal wtp increases with the duration of the outages and is higher if the outages occur during weekends and during winter months moreover the random parameter logit model allows us to estimate a sample distribution of wtp and we find a significant unobserved heterogeneity in some of the outage attributes given that households have negative welfare effects from outages it is important that policy makers consider these negative impacts on household utility when regulating the swedish electricity market

energy productivity and chinese local officials promotions evidence from provincial governors abstract improving energy productivity is one of the most cost effective ways to achieve a sustainable development target the existing literature has shown some factors that have driven the improvement in china s energy productivity however these studies do little to tackle the role of chinese local officials political promotions can be seen as the most important career incentive for chinese local officials hence we intend to study whether energy productivity affects chinese local officials promotions in this paper the data of position changes for the 31 provincial governors during 1978 2012 are utilized we adopted probit models to empirically examine the correlation between provincial governors political promotions and energy productivity the empirical results demonstrate that 1 energy productivity has a significantly positive impact on provincial governors political promotions in china meaning that the provincial governors have the momentum to improve energy productivity and 2 the effect of energy productivity on provincial governors political promotions has evolved dynamically changing along with the transformation of the economic growth mode and the adjustment of the local officials promotion mechanism the results are helpful in understanding the drivers of the improvement in china s energy productivity and provide insightful implications for conducting energy policy in china

estimating the linkage between energy efficiency and productivity abstract many analyses have referred to industrial productivity benefits associated with energy efficiency that are at least as great or larger than the energy benefits if plants with higher energy intensity also tend to have lower productivity then energy policy needs to consider this this study examines this issue for two segments of the glass industry using plant level data from the census bureau productivity is defined by the difference in best practice production efficiency as measured by data envelopment analysis dea this study uses regression analysis to estimate how differences in plant level electricity and fossil fuel intensity i e energy use per unit of production are attributable to differences in plant level productivity and other economic variables like energy prices and cumulative production in every case productivity differences between plants are statistically significant in explaining differences in plant energy intensity the coefficient that links productivity to energy efficiency yields a less than proportional impact for only one industry and fuel type for others the relationship is implies that a 1 increase in productivity increase energy efficiency by more than 1 this effect is statistically significant for flat glass but not container glass the estimates of the price and learning by doing coefficients seem reasonable but without imposing the assumption that all plants in the industry are equally productive this lends further credence to a significant relationship between productivity and energy efficiency

crude oil and stock markets stability instability and bubbles abstract we analyze the long run relationship between the world price of crude oil and international stock markets over 1971 1 2008 3 using a cointegrated vector error correction model with additional regressors allowing for endogenously identified breaks in the cointegrating and error correction matrices we find evidence for breaks after 1980 5 1988 1 and 1999 9 there is a clear long run relationship between these series for six oecd countries for 1971 1 1980 5 and 1988 2 1999 9 suggesting that stock market indices respond negatively to increases in the oil price in the long run during 1980 6 1988 1 we find relationships that are not statistically significantly different from either zero or from the relationships of the previous period the expected negative long run relationship appears to disintegrate after 1999 9 this finding supports a conjecture of change in the relationship between real oil price and real stock prices in the last decade compared to earlier years which may suggest the presence of several stock market bubbles and or oil price bubbles since the turn of the century

separating bric using islamic stocks and crude oil dynamic conditional correlation and volatility spillover analysis abstract this paper explores the dynamic conditional correlation and volatility linkage between islamic indexes and oil for bric countries correlations between these assets increase during the global financial crisis for india and china but not for brazil and russia the volatility error forecast variance of all five indexes comes from spillover but is much lower compared to volatility spillover between conventional indexes and oil hedging performance of islamic indexes are superior in india and china compared to conventional indexes in emerging markets an optimal minimum variance portfolio without reducing expected return can be achieved by investing in lower weights of bric islamic indexes and oil compared to conventional indexes

finance and the sources of growth the authors evaluate whether the level of development in the banking sector exerts a causal impact on economic growth and its sources total factor productivity growth physical capital accumulation and private saving they use 1 a pure cross country instrumental variable estimator to extract the exogenous component of banking development and 2 a new panel technique that controls for country specific effects and endogeneity they find that banks do exert a large causal impact on total factor productivity growth which feeds through to overall gdp gross domestic product growth the long run links between banking development and both capital growth and private savings are more tenuous

response bias in a conjoint analysis of power outages abstract a methodology is proposed for estimating status quo effects resistance to change and loss aversion willingness to pay is less than willingness to accept from consumer survey data conjoint data on israeli households attitudes to electricity outages reveal that both of these effects are pronounced and that they depend on the interviewees characteristics ordered conditional logit estimation indicates that while the estimates are rank sensitive the suggested methodology continues to be applicable finally the conjoint estimates are compared with those obtained by applying the method of contingent valuation

the willingness to pay by households for improved reliability of electricity service in north cyprus abstract this research examines households willingness to pay wtp for an improved electricity service households wtp is estimated using the payment ladder contingent valuation cv data from 350 in person interviews in north cyprus in order to avoid the cost of outages households are willing to incur a 13 8 increase in their monthly electricity bill a cost benefit analysis cba indicates that the annualized economic benefits of improved reliability of the electricity service would be approximately usd 35 6 million for the residential sector this figure is more than enough to finance the investments needed to completely eradicate any electricity outages in addition the fuel savings from substituting the generation of the new plants for the old plants would yield about usd 32 9 million per year in fuel savings hence a change from the current low reliability policy to one of providing a high quality service would yield an economic net present value to the residents of north cyprus of twice the investment costs or usd 173 3 million within five years

on the dynamic links between commodities and islamic equity abstract this paper investigates whether commodities offer potential diversification benefits for islamic equity index investors in light of possible financialization of commodity markets using mgarch dcc and wavelet coherence analyses our findings reveal that correlations between commodity markets and the dow jones islamic market world index are time varying and highly volatile throughout the january 1999 april 2015 period a substantial and persistent increase was observed in the return correlations between commodities and islamic equity at the onset of the 2008 financial crisis however trends in the recent two years suggest that this association is heading towards its pre crisis levels offering again diversification benefits for islamic equity holders these benefits vary across different commodities in various time scales overall gold natural gas soft commodities grains and livestock are better portfolio diversifiers than oil and other metals relative to medium to long term investors short term investors less than 32 days horizon gained better diversification benefits in most commodities during bullish bearish and market recovery periods these findings have implications for investors who are heterogeneous in risk tolerance and time preference as well as for policymakers who are concerned with market stability

willingness to pay and willingness to accept how much can they differ comment i agree with the point made by edoh y amiran and daniel a hagen 2003 that there can be a substantial or even infinite divergence between the wta and wtp for a public good even where there is a nonzero elasticity of substitution between market goods and the public good provided that the indifference curves are asymptotically bounded with respect to market goods in the manner they describe this is an important point they are also correct to point out that the elasticity of substitution is a local concept whereas their asymptotic boundedness condition applies also for discrete changes my 1991 paper used a local analysis because it was following the structure of the analysis in robert d willig 1976 and alan randall and john r stoll 1980 i wanted to show that while randall and stoll appeared to extend willig s local result on wta versus wtp from price changes to changes in the quantity of a public good the relevant elasticity was in fact different and involved the substitution elasticity as well as the income elasticity i view these points by amiran and hagen as not two separate results but essentially the same result their asymptotic boundedness condition generalizes my zero elasticity of substitution condition to discrete changes the asymptotic boundedness condition can be expressed as follows assuming a bivariate utility function u x q and given a reference point x q associated with a reference utility level u u x q there exists some q q such that for all q q there exists no x such that u x q u in other words no amount of x can substitute for the reduction in public good from q to q q in the case of a zero elasticity of substitution q q but as amiran and hagen show in their theorem 1 this is unnecessarily restrictive when dealing with a discrete reduction in q furthermore their theorem 2 can be viewed as a special case of their theorem 1 in which q 0 which makes q an essential commodity it is well known in consumer theory that the wta to avoid the loss of an essential market good is infinite their theorem 2 extends this result to the case of an essential nonmarket good but as their theorem 1 shows essentialness is not necessary for an infinite wta the boundedness condition is the key and this implies a fundamental lack of substitutability between money market goods and the public good

welfare evaluations in contingent valuation experiments with discrete response data comment in the case of private goods individuals reveal their preferences in the market place no similar market mechanism exists in the case of public goods however one obvious possibility is to ask people about their maximal willingness to pay for public goods or government expenditure johansson 1987 1990 miller in some recent contingent market valuation studies people instead have been asked to accept or reject a specified amount of money for a change in the provision of a public good different subsamples are confronted with different bids the resulting yes and no responses usually are analyzed by logit or probit techniques e g johansson and kristrom this raises the question of how to compute the average willingness to pay when only yes and no responses are available this point was advanced by hanemann in his seminal 1984 paper on welfare evaluations with discrete responses see also hanemann 1987 however we believe a minor imperfection in hanemann s presentation may confuse and mislead practitioners hanemann s approach assumes that negative bids cannot occur but at the same time gives the impression that it also applies to models that allow for negative bids we also extend hanemann s discussion of the choice of money measure in cost benefit analysis

exogenous oil supply shocks how big are they and how much do they matter for the u s economy abstract the paper proposes a new measure of exogenous oil supply shocks the timing the magnitude and the sign of this measure may differ greatly from current state of the art estimates it is shown that only a small fraction of the observed oil price increases during oil crisis periods can be attributed to exogenous oil production disruptions exogenous oil supply shocks cause a sharp drop of u s real gdp growth after five quarters rather than an immediate and sustained reduction in economic growth and a spike in cpi inflation after three quarters overall exogenous oil supply shocks made remarkably little difference for the evolution of the u s economy since the 1970s although they did matter for some historical episodes

the impact of financial development on energy consumption in emerging economies abstract financial development is often cited as a very important driver of economic growth in emerging economies and it is thus likely that financial development affects energy demand this study uses generalized method of moments estimation techniques to examine the impact of financial development on energy consumption in a sample of emerging countries several different measures of financial development are examined using a panel data set on 22 emerging countries covering the period 1990 2006 the empirical results show a positive and statistically significant relationship between financial development and energy consumption when financial development is measured using stock market variables like stock market capitalization to gdp stock market value traded to gdp and stock market turnover the implications of these results for energy policy are discussed

does higher economic and financial development lead to environmental degradation evidence from bric countries abstract a vast number of studies addressed the environmental degradation and economic development but not financial development moreover as argued by stern 2004 the rise and fall of the environmental kuznets curve world development 32 1419 1439 they present important econometric weaknesses using standard reduced form modeling approach and controlling for country specific unobserved heterogeneity we investigate the linkage between not only economic development and environmental quality but also the financial development panel data over period 1992 2004 is used we find that both economic and financial development are determinants of the environmental quality in bric economies we show that higher degree of economic and financial development decreases the environmental degradation our analysis suggests that financial liberalization and openness are essential factors for the co 2 reduction the adoption of policies directed to financial openness and liberalization to attract higher levels of r d related foreign direct investment might reduce the environmental degradation in countries under consideration in addition the robustness check trough the inclusion of us and japan does not alter our main findings

households willingness to pay for water service attributes water consumption and disposal are often taken for granted as essential services with required levels of service quality yet little is known about how much consumers are willing to pay for specific service levels as customers in many countries face changing levels of water availability especially shortages linked possibly to climate change and limited catchment capacity the need to assess the value and hence benefit to society of varying service levels and prices in an effort to secure the provision of and disposal of water has risen on public agendas in an attempt to establish how much customers are willing to pay for specific levels of service we use a series of stated choice experiments and mixed logit models to establish the willingness to pay to avoid interruptions in water service and overflows of wastewater differentiated by the frequency timing and duration of these events the empirical evidence is an important input into the regulatory process for establishing service levels and tariffs as well as useful planning information for agencies charged with finding cost effective ways of delivering services at prices that customers deem to be value for money

islamic stocks conventional stocks and crude oil directional volatility spillover analysis in brics abstract this paper uses threshold garch tgarch and generalised forecast error variance decomposition to compute time domain and frequency domain volatility spillover the spillover technique is then applied to islamic and conventional stock indices and crude oil in brics countries brazil russia india china and south africa thus informing investors about the magnitude and speed of the volatility spillover we find that the total volatility spillover is driven mainly by a long term component accordingly these assets are suitable for investors with short and medium term investment horizons however analysis reveals that volatility spillover magnitude and speed increase substantially during the global financial crisis suggesting that investors in brazil russia and south africa with stocks in their portfolio should rebalance promptly dynamic covariance analysis shows that covariance between islamic and conventional stock index returns is the highest and exhibit a significant increase during the crisis period

green productivity growth in china s industrial economy abstract this paper uses a directional distance function ddf and the malmquist luenberger productivity index to estimate the changing patterns of green total factor productivity gtfp growth of 38 chinese industrial sectors during the period 1980 2010 unlike the measures of traditional total factor productivity tfp growth the ddf incorporates carbon dioxide emissions as an undesirable output directly into the production technology which credit sectors for simultaneously reducing their emissions and increasing their output our estimates of aggregate and sector level gtfp growth reveal that chinese industry is not yet on the path towards sustainable low carbon growth a dynamic panel data analysis of the determinants of gtfp across sectors is used to identify factors that might rectify this situation including state owned enterprise soe reform the growth of small private enterprises continued openness to foreign investment and higher spending on r d particularly in emission intensive sectors

electricity tariffs in india an assessment of consumers ability and willingness to pay in gujarat abstract a sample of electricity consumers covering agricultural residential and industrial consumers in the indian state of gujarat was surveyed in 1997 to investigate the consumers ability and willingness to pay for electricity supplied from the grid the ability to pay was estimated using the weight of the cost of electricity to meet at least the basic household needs in relation to the overall income or expenditure the willingness to pay was estimated using the costs of meeting the needs by alternative sources of energy namely diesel in the case of farmers to pump water for irrigation and captive power generation using diesel generators in the case of industrial users survey results reveal the proportion of consumers in different categories which do not have the ability to pay more or are even not willing to pay more for electricity the survey findings have been used as a guideline in the proposed adjustment of tariffs charged by the gujarat electricity board

energy use and structural changes factors behind the fall in sweden s energy output ratio abstract this paper examines the causes behind the fall in sweden s use of energy in relation to real gdp after the energy crisis 1973 1974 the author uses historical and statistical data as well as economic theory especially input output analysis to analyse effects on the energy output ratio of the changes in sectoral energy use and of variations in the composition of final demand the results obtained are used to assess the energy implications of alternative strategies for economic policy actually discussed in sweden for the early 1980s

using a choice experiment to account for preference heterogeneity in wetland attributes the case of cheimaditida wetland in greece abstract this paper aims to assist policy makers in formulating efficient and sustainable wetland management policies in accordance with the ramsar convention and the european union water framework directive 2000 60 ec by providing results of a valuation study on the cheimaditida wetland in greece a choice experiment is employed to estimate the values of changes in several ecological social and economic functions that cheimaditida wetland provides to the greek public in addition to the conditional logit model a random parameter logit model a random parameter logit model with interactions and a latent class model are estimated to account for heterogeneity in the preferences of the public for the various functions of the wetland the results reveal that there is considerable preference heterogeneity across the public and on average they derive positive and significant values from sustainable management of this wetland the estimated economic benefits of sustainable wetland management are weighed against the costs of alternative wetland management scenarios results of this cost benefit analysis can aid in the design of socially optimal policies for sustainable management of the cheimaditida wetland with possible implications for other similar wetlands in greece and the rest of europe

estimating the willingness to pay for water services in developing countries a case study of the use of contingent valuation surveys in southern haiti progress in improving the quality and quantity of water used by people in rural areas of the developing world has been unsatisfactory in two respects 1 supplies that have been built are frequently neither used correctly nor properly maintained and 2 extension of improved service to unserved populations has been slow though this poor record is not the result of a single factor a major impediment to improved performance is inadequate information on the response of consumers to new service options the behavioral assumptions that typically underlie most rural water supply planning efforts are simple it is commonly assumed that so long as financial requirements do not exceed 5 of income rural consumers will choose to abandon their existing water supply in favor of the improved system several reviews by the world bank bilateral donors and water supply agencies in developing countries have shown however that this simple model of behavioral response to improved water supplies has usually proved incorrect 1 in rural areas many of those served by new systems have chosen to continue with their traditional water use practices

protest responses in contingent valuation a significant number of respondents to contingent valuation surveys tend to either state a zero bid or refuse to state a bid at all for reasons associated with the process of valuation these protest responses are routinely removed from contingent valuation samples because it is assumed that they are not indicative of respondents true values the censoring of protest responses has led to the emergence of a definitional controversy one view is that the definition of protest responses and the rules for censoring them are dependent on whether the practitioner conceives of the contingent valuation survey as a market or as a referendum however what is not acknowledged is the possibility that protest responses and their meaning may vary according to the type of good being valued the elicitation format and the interaction between these elements and external factors this potential renders the development of unambiguous rules for censoring protest responses difficult moreover when willingness to pay is viewed as a behavioural intention it becomes important to determine what the responses actually mean this approach does not assume an interpretative position a priori against which the responses should be judged but seeks to inform an existing understanding which is inadequate

reliability worth assessment in a developing country residential survey results this paper presents the results of a residential customer survey conducted in service areas of the nepal integrated electric power system nps the objective was to determine the power interruption costs incurred by the residential customers of a developing country and extend the customer survey approach to reliability worth evaluation in a developing environment interruption cost estimates were obtained using in person interviews with 944 sample customers the results indicate the implications of service reliability to residential customers of nepal and show that reliability worth evaluation in a developing country is both possible and practical

the value of online banking to small and medium sized enterprises evidence from firms operating in the uae free trade zones abstractthis study estimates the willingness to pay of small and medium sized enterprises smes for a business online banking services the estimation utilizes a contingent valuation method employing data from 400 smes in the united arab emirates free zones an interval regression model is used to identify company characteristics affecting wtp the results indicate an average wtp for online banking of 518 50 per month firms engaging in international trade value these services at least 10 more than those with only domestic operations other variables that significantly affect wtp include number of employees and the transportation cost of using traditional branch banking

financial development and economic growth views and agenda this critique argues that the preponderance of theoretical reasoning and empirical evidence suggests a positive first order relationship between financial development and economic growth the body of work would push even most skeptics toward the belief that the development of financial markets and institutions is a critical and inextricable part of the growth process and away from the view that the financial system is an inconsequential sideshow responding passively to economic growth many gaps remain however and the paper highlights areas in acute need of additional research

do structural oil market shocks affect stock prices abstract this paper investigates how explicit structural shocks that characterize the endogenous character of oil price changes affect stock market returns in a sample of eight countries australia canada france germany italy japan the united kingdom and the united states for each country the analysis proceeds in two steps first modifying the procedure of kilian kilian l forthcoming not all oil price shocks are alike disentangling demand and supply shocks in the crude oil market american economic review we employ a vector error correction or vector autoregressive model to decompose oil price changes into three components oil supply shocks global aggregate demand shocks and global oil demand shocks the last component relates to specific idiosyncratic features of the oil market such as changes in the precautionary demand concerning the uncertainty about the availability of future oil supplies second recovering the oil supply shocks global aggregate demand shocks and global oil demand shocks from the first analysis we then employ a vector autoregressive model to determine the effects of these structural shocks on the stock market returns in our sample of eight countries we find that international stock market returns do not respond in a large way to oil market shocks that is the significant effects that exist prove small in magnitude

relationship lending hierarchical distance and credit tightening evidence from the financial crisis abstract this paper examines the firms credit availability during the 2007 2009 financial crisis using a dataset of 5331 bank firm relationships provided by borrowers credit folders of three italian banks it aims to test whether a strong lender borrower relationship can produce less credit rationing for borrowing firms even during a credit crunch period the results show that exclusivity of the relationship can mitigate the firm credit rationing we also verify the influence of lending organizational structure during crisis a new measure of distance in lending technologies has been introduced the hierarchical distance calculated as the distance between the branch that originates the loan and the location of the hierarchical level responsible for financing decision our findings document a negative impact of distance on credit availability consistent with the idea that proximity facilitates the transmission of soft information

estimating the willingness to pay for reliable electricity supply a choice experiment study abstract this research examines households willingness to pay wtp for an improved electricity service households stated wtp is estimated using the choice experiment ce method the data used in the estimations come from 350 in person interviews conducted during the period 5 22 august 2008 in north cyprus compensating variation cv estimates for a zero outage scenario are calculated using the parameter estimates from the mixed logit ml model these are 6 65 ytl turkish lira per month 3 02 usd for summer and 25 83 ytl per month 11 74 usd for winter in order to avoid the cost of outages households are willing to incur a 3 6 and a 13 9 increase in their monthly electricity bill for summer and winter respectively the wtp per hour unserved is 0 28 ytl 0 13 usd for summer and 1 08 ytl 0 49 usd for winter a preliminary cost benefit analysis indicates that the annualized economic benefits are approximately 42 7 million ytl 19 4 million usd for the residential sector this would justify an investment in additional generation capacity of approximately 268 mw which is far more than that which is needed to eliminate the service reliability problem

what drives energy efficiency new evidence from financial crises abstract using a sample of 100 countries from 1980 to 2015 this paper investigates the impact of foreign direct investment fdi imports gross capital formation and industry value added on energy efficiency before and after the 2008 global financial crisis our findings reveal that failing to control for economic downturns may lead to misleading results moreover we find that the effects of these channels are different between low middle and high income countries our study also shows that the effect of fdi on energy savings is inverted u shaped whereas the effect of imports on energy savings is u shaped when we control for the income level of the countries
