an analysis of the driving forces of energy related carbon dioxide emissions in china s industrial sector abstract both energy consumption and the growth of carbon dioxide co2 emissions in china are attributed to the industrial sector energy conservation and co2 emissions reduction in china s industrial sector is decisive for achieving a low carbon transition we analyze the change of energy related co2 emissions in china s industrial sector from 1991 to 2010 based on the logarithmic mean divisia index lmdi method results indicate that industrial activity is the major factor that contributes to the increase of industrial co2 emissions while energy intensity is the major contributor to the decrease of co2 emissions industry size shows a varying trend interchanging intervals of growth along the study period moreover both energy mix and carbon intensity of energy use have negative effects on the increase of co2 emissions the cointegration method is adopted to further explore determinants of co2 emissions in china s industrial sector results show that there exists a long run relationship between industrial co2 emissions and affecting factors such as co2 emissions per unit of energy consumption industrial value added labor productivity and fossil fuel consumption china s industrial co2 emissions are mainly attributed to the coal dominated energy structure policy suggestions are thus provided to reduce industrial co2 emissions in china

financial contracting theory meets the real world an empirical analysis of venture capital contracts we compare the characteristics of real world financial contracts to their counterparts in financial contracting theory we do so by studying the actual contracts between venture capitalists vcs and entrepreneurs the distinguishing characteristic of vc financings is that they allow vcs to separately allocate cash flow rights board rights voting rights liquidation rights and other control rights we describe and measure these rights we then interpret our results in relation to existing financial contracting theories we also describe the interrelation and the evolution across financing rounds of the different rights query 1 query 2

changing energy intensity of economies in the world and its decomposition abstract this paper decomposes energy intensity change across countries into five components attributable to technological catch up technological progress and changes in capital energy ratio labor energy ratio and output structure it is found that 1 technological progress capital accumulation and output structure change contributed to the decline of energy intensity from 1980 to 2010 2 changes in labor energy ratio drove up energy intensity and 3 spatial and temporal heterogeneity existed regarding relative importance of the five components

rewarding risk taking or skill the case of private equity fund managers abstract we examine whether typical private equity fund compensation contracts reward excessive risk taking rather than managerial skill our analysis is based on a novel model of investment value cash flows and fee dynamics of private equity funds given the embedded option like fee components our results demonstrate that fund managers indeed have an incentive for excessive risk taking when only fee income from the current fund is considered however when managers also consider potential compensation from follow on funds their risk taking incentives depend on their individual skill levels and skilled managers will have an incentive to reduce fund risk we also show that managers must generate substantial abnormal returns in order to compensate investors for the given fee components

the competitiveness of the uk aerospace industry porter s five competitive forces model provides an analytical framework for assessing the uk aerospace industry s competitiveness in this article various statistical indicators are used to measure competitiveness based on published data at the industry and firm level supplemented with information from company interviews the indicators include productivity output firm size development time scales labour hoarding exports and profitability the empirical results of this article suggest that over the period 1980 to 2000 the uk aerospace industry improved its competitiveness compared with the usa and the eu

comment on bergemann and hege dirk bergemann and ulrich hege examine in this paper the reasons why venture capitalists provide funds to entrepreneurs in successive financing rounds or stages this is an interesting analysis of one of the most important mechanisms that venture capitalists employ to control entrepreneurs an issue that surely deserves greater theoretical and empirical attention the authors approach to these issues is a creative and novel one at the same time some assumptions and predictions of the model seem quite at odds with the empirical evidence about venture capital investments in this discussion i will first briefly summarize the key features and predictions of the paper i will then highlight several of my concerns with the model the discussion concludes with some more general thoughts about the rationales for the staging of venture capital investments in young firms the paper depicts the interactions between a single entrepreneur and a venture investor the entrepreneur who has no financial resources must turn to a venture capitalist for funding it is assumed that the entrepreneur initially has the bargaining power in the negotiation the large number of potential venture investors are not diaerentiated dynamic interactions between several venture capitalists in diaerent financing rounds of the type analyzed by admati and pfleiderer 1994 are not considered in this model the project whose quality is initially uncertain can turn out to be one of two types good or bad the good projects are not revealed immediately rather in each period there is some probability that the project will be revealed to be good and generate a fixed return at which point the venture investor s involvement ends the probability of a successful outcome is increasing with

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

cross border venture capital investments the impact of foreignness on returns against the background of the growing internationalization of venture capital vc investing this is the first global comparison of the returns generated by individual domestic and cross border deals we examine investments worldwide during 1971 2009 and find that cross border investments significantly underperform compared with equivalent domestic investments returns are negatively affected by geographic distances cultural disparities and institutional differences between the home and host countries returns on cross border and domestic deals also decline after the late 1990s international portfolio diversification and the saturation of domestic markets may explain why vc investors make cross border investments despite poor expected returns

renewable energy policy framework and bioenergy contribution in the european union an overview from national renewable energy action plans and progress reports abstract the use of renewable energy is projected to increase substantially in the european union to reach a share of 20 in final energy consumption and 10 renewable energy in transport by 2020 the renewable energy contribution is further expected to increase to 55 75 of gross final energy consumption in 2050 according to the latest reports the european union has made significant progress since 2005 and is on track to reach its 2020 renewable energy targets this paper provides a review of the policy framework for renewable energy in the european union and an analysis of the progress made by the use of renewable energy as well as the expected developments until 2020 and beyond it focusses on the contribution of bioenergy the major source among renewables in the european union as biomass availability is a critical issue for the bioenergy production this paper provides an analysis of the biomass demand for reaching the 2020 targets in relation with the expected domestic supply and biomass potential

development of the wind power in brazil political social and technical issues abstract this paper aims to present a review of the increasing contribution of wind power to the brazilian electric matrix and an analysis of the main impact on technical political and social aspects this work takes into account the state of art of the wind power technology the wind resource potential and the evolution of installed capacity in the country the institutional programs and the fiscal incentives provided by the brazilian government are also discussed in this paper including its impacts on the society we have reviewed national and international reports and relevant scientific papers to realize this work the analysis shows that electric crisis in 2001 led the brazilian government to develop new energy policies that supported the rapid growth of the wind industry from imported technology later on in the year 2004 the government mandated that the technology be developed within the country it is expected that from 2011 of approximately 1500 mw until 2021 the installed wind capacity would increase by a factor of 600 however the national technology acquisition and development is still incipient it is important to produce locally wind turbine components and is highly desirable to increase collaboration between industries and universities in the country

how economic growth affects emissions an investigation of the environmental kuznets curve in portuguese and spanish economic activity sectors abstract it is a disquieting reality that increased economic growth for many years now in the western world is at odds with environmental degradation in this paper the relationship between economic growth and environmental variables is analyzed under two non linear specifications a quadratic and a cubic specification the study is conducted for portugal and spain in the period 1975 2012 using data for 13 sectors gva is used as proxy for income while energy use and carbon dioxide account for environmental degradation there is evidence for an inverted u shaped ekc however there are also other inverted n shaped functions that explain the relationship between economic growth and emissions altogether empirical results do indicate particular differences between portuguese and spanish sectors the results are of interest not only for researchers but also for policy makers political mitigation measures are also analyzed

indirect carbon emissions of urban households in china patterns determinants and inequality abstract the urban household sector is considered to be an essential source of climate change in order to obtain detailed information concerning the description of household consumption activities this paper combined consumer lifestyle approach and input output analysis to estimate indirect carbon emissions of urban household from 2002 to 2012 besides we further analysed the driving forces and inequality of indirect carbon emissions the results showed that the total indirect carbon emissions during the study period increased rapidly rising from 894 08 mtco2 to 1957 03 mtco2 more than 58 of carbon emissions were from 40 of the high income population the highest income group 10 of total urban households deduced 21 of urban indirect carbon emissions the per capita carbon emissions of different households showed a remarkable disparity and the per capita carbon emissions of high income groups decreased from 2011 to 2012 the effective mitigation efforts should focus on reducing carbon intensity and shifting consumption structure for high inequality consumption activities caused by rich households rich urban households should consume less goods and services from this consumption activities for high inequality consumption activities caused by low income households the redistribution of income from rich to poor and low carbon intensity lifestyles may be better options to reduce carbon emissions and inequalities of urban households

decomposition of co2 emissions change from energy consumption in brazil challenges and policy implications this study evaluates the changes in co2 emissions from energy consumption in brazil for the period 1970 2009 emissions are decomposed into production and consumption activities allowing computing the full set of energy sources consumed in the country this study aims to develop a comprehensive and updated picture of the underlying determinants of emissions change from energy consumption in brazil along the last four decades including for the first time the recently released data for 2009 results demonstrate that economic activity and demographic pressure are the leading forces explaining emission increase on the other hand carbon intensity reductions and diversification of energy mix towards cleaner sources are the main factors contributing to emission mitigation which are also the driving factors responsible for the observed decoupling between co2 emissions and economic growth after 2004 the cyclical patterns of energy intensity and economy structure are associated to both increments and mitigation on total emission change depending on the interval the evidences demonstrate that brazilian efforts to reduce emissions are concentrated on energy mix diversification and carbon intensity control while technology intensive alternatives like energy intensity has not demonstrated relevant progress residential sector displays a marginal weight in the total emission change

comparing structural decomposition analysis and index to analyze and understand historical changes in economic environmental employment or other socio economic indicators it is useful to assess the driving forces or determinants that underlie these changes two techniques for decomposing indicator changes at the sector level are structural decomposition analysis sda and index decomposition analysis ida for example sda and ida have been used to analyze changes in indicators such as energy use co2 emissions labor demand and value added the changes in these variables are decomposed into determinants such as technological demand and structural effects sda uses information from input output tables while ida uses aggregate data at the sector level the two methods have developed quite independently which has resulted in each method being characterized by specific unique techniques and approaches this paper has three aims first the similarities and differences between the two approaches are summarized second the possibility of transferring specific techniques and indices is explored finally a numerical example is used to illustrate differences between the two approaches

key drivers for unsustainable resource use categories effects and policy pointers abstract prevailing resource use patterns of the global socio industrial metabolism are unsustainable an increasing number of people globally require ever more materials including energy carriers land and water for rising living standards and lifestyles converging towards western industrialised patterns therefore these resources will continue becoming both scarcer and depleted while environmental impacts associated with their consumption e g run away climate change will continue to rise for effective resource policies drivers for such unsustainable resource use and their effects need to be better understood and mapped by means of meta analysis of more than 60 sources of relevant literature we identified a set of ten driver categories that affect unsustainable resource use inter alia prevailing consumption and production patterns use and design of infrastructure and technology underlying paradigms and world views resource prices and the level of knowledge and information of resource users cumulative effects of the drivers contribute for instance up to 30 of phosphorus loss from soil and around 30 of building energy loss globally although the data does not allow clear cut causal attribution of effects it enables the distinction between direct and indirect drivers in relation to a multi dimensional network of drivers causing unsustainable resource use resource policy should combine policy objectives and instruments into policy mixes to target key drivers and their interrelations while policy mixes need to respond to context specific driver settings targeting consumer behaviour emerges as a general driver focus of policy mixes combining different instrument types and implementing them in a time dynamic sequence can mitigate trade offs between different instruments and in the longer term increase feasibility of profound behaviour changes

mitigating climate change decomposing the relative roles of energy conservation technological change and structural shift abstract we decompose the contribution of five drivers of energy use and co 2 emissions reductions in achieving climate change goals over 2005 2100 for various climate policy scenarios this study contributes to the decomposition literature in three ways first it disaggregates drivers of energy demand into technological progress and demand for energy services represented in terms of useful energy allowing us to estimate their contributions independently an improvement over other economy wide decomposition studies secondly this approach reduces the ambiguity present in many previous measures of structural change we delineate structural shifts into two separate measures changes in fuel mix within a given resource or service pathway and changes in mix among distinct energy resources or end use services finally this study applies decomposition methods to energy and emission trajectories from two mutually informing perspectives i primary energy resources crude oil natural gas coal nuclear and renewables and ii end uses of energy services residential and commercial buildings industry and transportation our results show that technological improvements and energy conservation are important in meeting climate goals in the first half of the coming century and that nuclear and renewable energy and ccs technology are crucial in meeting more stringent goals in the second half of the century we examine the relative roles of the drivers in reducing co 2 emissions separately for developed and developing regions although the majority of energy and emission growth and by extension the greatest opportunities for mitigation will occur in developing countries the decomposition shows that the relative roles of the five drivers are broadly consistent between these two regions

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

does federally financed business r d matter for us productivity growth this paper investigates the impact of federally financed business r d on productivity of the us nonfarm business sector results of a cointegration analysis suggest that a long run relation between productivity and total privately and federally financed r d capital stock exists moreover the estimation results do not confirm the finding of previous empirical studies that the productivity effects of federally financed business r d are lower compared with those of privately financed business r d

the effect of capital market characteristics on the value of start up firms we develop an equilibrium model of contracting bargaining and search in which the relative scarcity of venture capital affects the bargaining power of entrepreneurs and venture capitalists this in turn affects the pricing contracting and value creation in start ups the relative scarcity of venture capital is endogenous and depends on the profitability of venture capital investments entry costs and transparency of the venture capital market supply and demand conditions also affect the incentives of venture capitalists to screen projects ex ante we characterize both the short and long run dynamics of the venture capital industry which provides us with a stylized picture of the internet boom and bust periods our model is consistent with existing evidence and provides a number of new empirical predictions

stage financing and the role of convertible securities venture capital financing is characterized by extensive use of convertible securities and stage financing in a model where a venture capitalist provides staged financing for a project we illustrate an advantage of convertible debt or warrants over a mixture of debt and equity essentially when the venture capitalist retains the option to abandon the project the entrepreneur has an incentive to engage in window dressing and bias positively the short term performance of the project reducing the probability that it will be liquidated an appropriately designed convertible security prevents such behaviour because window dressing also increases the probability that the venture capitalist will exercise the conversion option becoming the owner of a substantial fraction of the project s equity

staged financing an agency perspective this paper investigates the structure of outside investment in a profitable entrepreneurial venture though efficient financing the venture up front may be infeasible because the entrepreneur cannot commit to not renegotiate down the outside investor s claim once she s sunk her investment staging the investment over time helps to mitigate this commitment problem the early rounds of investment create collateral that support the later rounds we characterize the optimal staged investment path and show how it is affected by various features of the venture the predictions of the model are consistent with observations on staged financing in venture capital

energy intensity a decomposition and counterfactual exercise for latin american countries abstract this paper investigates trends in energy intensity over the last 40 years based on a sample of 75 countries it applies the fisher ideal index to decompose the energy intensity into the relative contributions of energy efficiency and economic structure then the determinants of these energy indexes are examined through panel data regression techniques special attention is lent to latin american countries lac by comparing its performance to that of a similar set of countries chosen through the synthetic control method when analyzed by income level energy intensity has decreased in a range between 40 and 54 in low and medium income countries respectively efficiency improvements drive these changes while the structural effect does not represent a clear source of change the regression analysis shows that per capita income petroleum prices fuel energy mix and gdp growth are main determinants of energy intensity and efficiency while there are no clear correlations with the activity component in the case of lac the energy intensity decreased around 20 which could be interpreted as an under performance however the counterfactual exercise suggests that lac has closed the gap with respect to its synthetic control

robust financial contracting and the role of venture capitalists we derive a role for inside investors such as venture capitalists in resolving various agency problems that arise in a multistage financial contracting problem absent an inside investor the choice of securities is unlikely to reveal all private information and overinvestment may occur an inside investor however always makes optimal investment decisions if and only if he holds a fixed fraction contract where he always receives a fixed fraction of the project s payoff and finances that same fraction of future investments this contract also eliminates any incentives of the venture capitalist to misprice securities issued in later financing rounds in this article we develop a model of financial contracting with multiple investment decisions and show how conflicts of interest and informational asymmetries can be effectively resolved by an inside investor i e an investor who not only provides capital but also works closely with the firm monitors it frequently and is generally very well informed about the firm s prospects and investment opportunities venture capitalists are obvious examples of inside investors and their function has been an important motivation for this article banks especially in japan and germany are also involved in monitoring and can be viewed as playing the role of inside investors in this article we examine the potential benefits of inside investors in a context where there are no restrictions beyond limited liability on the type of financial contracts that can be written we address a basic financial contracting problem involving an entrepreneur who has an idea for a project but does not have sufficient capital to fund it an important assumption is that there are several stages in the project s development and that a decision must be made at each stage whether the project should be continued or abandoned if the project is continued the amount of additional capital to be invested must also be determined we assume that the entrepreneur as an insider observes private information about the project s profitability at each stage this information is not

decomposition analysis of debt s impact on china s energy consumption abstract debt can influence the energy consumption of private sectors and public agencies by changing their fiscal budget constraints from 1996 to 2016 china has had rapid debt growth and become the second largest borrower in the world additionally china has been the largest energy consumer since 2009 the impact of debt growth on its energy consumption however is not much addressed in the literature using an extended lmdi model we investigate the impact of china s debt on its energy consumption from 1996 to 2016 in a new way the results show that 1 among the closed set of debt related factors and other conventional variables studied private debt per capita makes the strongest contribution to china s energy consumption and population has a moderate impact on the growth of energy consumption 2 energy efficiency improvement output efficiency of government debt debt structure adjustment and increased tertiary industry share are mitigating forces of energy consumption these results provide a new holistic perspective for the chinese government to formulate synergistic policies of risk control and pollution control

energy for sustainable development a case of developing countries abstract today there are 1 4 billion people around the world that lack access to electricity some 85 of them in rural areas without additional dedicated policies by 2030 the number of people drops but only to 1 2 billion some 15 of the world s population still lack access the majority of them living in sub saharan africa the number of people relying on the traditional use of biomass is projected to rise from 2 7 billion today to 2 8 billion in 2030 addressing these inequities depends upon international recognition that the projected situation is intolerable a commitment to effect the necessary change and setting targets and indicators to monitor progress a new financial institutional and technological framework is required as is capacity building in order to dramatically scale up access to modern energy services at the local and regional levels in this paper we discussed the energy situation of the developing countries for sustainable development

energy intensity developments in 40 major economies structural change or technology improvement this study analyzes energy intensity trends and drivers in 40 major economies using the wiod database a novel harmonized and consistent dataset of input output table time series accompanied by environmental satellite data we use logarithmic mean divisia index decomposition to 1 study trends in global energy intensity between 1995 and 2007 2 attribute efficiency changes to either changes in technology or changes in the structure of the economy and 3 highlight sectoral and regional differences we first show that heterogeneity within each sector across countries is high these general trends within the sectors are dominated by large economies first and foremost the united states in most cases heterogeneity is lower within each country across the different sectors regarding changes of energy intensity at the country level improvements between 1995 and 2007 are largely attributable to technological change while structural change is less important in most countries notable exceptions are japan the united states australia taiwan mexico and brazil where a change in the industry mix was the main driver behind the observed energy intensity reduction

how much co2 emissions do we reduce by saving electricity a focus on methods abstract in this paper we evaluate two approaches for estimating co2 emission reduction from electricity savings one based on average co2 intensities of electricity generation and another that relies on marginal co2 intensities it is found that the average co2 intensity approach has a significant shortcoming when it comes to scenario based approaches for co2 emission reduction this shortcoming lies in the chicken egg problem created where larger future electricity savings are actually big enough to change the co2 intensity in such a way that it cannot be used anymore to estimate the co2 emission reduction we show that in these cases the marginal approach is preferred to correctly apply this approach it is important to determine the co2 intensity of the future power mix which will not be built in order to avoid under or overestimation of the co2 savings calculated we propose a seven step approach which can be used in scenario based potential studies as guidance for estimating the co2 emission reductions from not only electricity savings but also renewable electricity and mitigation options that consume electricity such as electric cars and heat pumps using our approach would avoid a disconnection of the co2 reduction potential with the underlying reference scenario

staging of venture capital investment a real options analysis this paper uses contingent claims analysis to investigate the staging decision of venture capitalist vc in a principal agent framework venture capital investment opportunities are modeled as real options with multiple volatilities and the entrepreneur s incentive is assumed to maximize the probability of getting funded in the next financing round two celebrated formulae in the option pricing literature are generalized to evaluate these real options we find that staging not only gives the vc a waiting option but also mitigates the agency problem of the entrepreneur undertaking too conservative activities moreover we find that the vc tends to stage her investment when the expected growth rate of the venture s market value is lower however the risk free interest rate is not an important factor in the staging decision our model also provides a good explanation for existing empirical evidence on the staging of venture capital investment

the effects of double counting and expensing on the measured returns to r d this article focuses on the effects of double counting and expensing on the measured returns to r d the contribution of research and development r d to economic growth has been measured in two general ways the first is to compute total factor productivity in a growth accounting framework and to attribute this residual growth to r d the prevailing view is that in the presence of double counting the measured contribution of r d represents the return above and beyond the normal remuneration to traditional capital author demonstrate that this excess returns interpretation eri is essentially correct in the growth accounting framework and that the resulting bias in the measured contribution of r d to growth is large in postwar u s manufacturing the measured residual is biased downward by as much as 30 the expensing bias is downward and reinforces the excess returns bias in this case and the total bias is large in both the growth accounting and econometric contexts the magnitude of the biases may vary across samples and over time there is simply no substitute for properly measured variables

venture capital financing moral hazard and learning we consider the provision of venture capital in a dynamic agency model the value of the venture project is initially uncertain and more information arrives by developing the project the allocation of the funds and the learning process are subject to moral hazard the optimal contract is a time varying share contract which provides intertemporal risk sharing between venture capitalist and entrepreneur the share of the entrepreneur reflects the value of a real option the option itself is based on the control of the funds the dynamic agency costs may be high and lead to an inefficient early stopping of the project a positive liquidation value explains the adoption of strip financing or convertible securities finally relationship financing including monitoring and the occasional replacement of the management improves the efficiency of the financial contracting

federal policies for renewable electricity impacts and interactions abstract three types of policies that are prominent in the federal debate over addressing greenhouse gas emissions in the united states are a cap and trade program ctp on emissions a renewable portfolio standard rps for electricity production and tax credits for renewable electricity producers each of these policies would have different consequences and combinations of these policies could induce interactions yielding a whole that is not the sum of its parts this paper utilizes the haiku electricity market model to evaluate the economic and technology outcomes climate benefits and cost effectiveness of three such policies and all possible combinations of the policies a central finding is that the carbon dioxide co2 emissions reductions from ctp can be significantly greater than those from the other policies even for similar levels of renewable electricity production since of the three policies ctp is the only one that distinguishes electricity generated by coal and natural gas it follows that ctp is the most cost effective among these approaches at reducing co2 emissions an alternative compliance payment mechanism in an rps program could substantially affect renewables penetration and the electricity price effects of the policies hinge partly on the regulatory structure of electricity markets which varies across the country

regional and sectoral attribution to percentage changes in the european divisia carbonization index abstract concerns on rising concentrations of co2 in the atmosphere and global warming have increased in recent years numerous environmental studies analyze the trends in co2 emissions and their main drivers in this paper we focus on the dynamics of the carbonization effect as a driving force for co2 emissions in the european union eu by implementing the sato vartia logarithmic mean divisia index method the trend of european emissions in the 2000 2010 period is factorized by both sector and country the analysis stresses the relevance of the carbonization and intensity effects in order to reduce emissions then based on so called attribution analysis we present a new theoretical framework that enables the attribution of both economic sector and individual eu member state to percentage changes in the carbonization index results show strong concentration of this reducing influence in some big economies in fact germany the united kingdom france and italy have contributed by more than 50 industry emerges as the most influential sector contributing to offset any improvement in the carbonization index our findings suggest strategies aiming at encouraging innovation technical change research on higher quality energies fuel substitution and installation of abatement technologies particularly in the industrial sector of large economies

the modest environmental relief resulting from the transition to the service economy a service transition is supposed to lead to the decline of energy intensity energy gdp we argue that this interpretation is overly optimistic because the shift to a service economy is somewhat of an illusion in terms of real production several recent studies of structural effects on energy intensity have made the error of using sector shares in current prices combined with gdp in constant prices which is inconsistent and ignores the different behaviour of prices across sectors we use the more correct method of sector shares in constant prices and make an attempt to single out the effect from the real service transition by using two complementary methods shift share analyses in current and constant prices and logarithmic mean divisia index lmdi for 10 developed and 3 emerging economies a service transition is rather modest in real terms the major driver of the decline in energy intensity rests within the manufacturing sector meanwhile the transition to a service sector had a small downward impact on energy intensity in 7 of the developed countries and no impact in the others for emerging economies like brazil mexico and india it is the residential sector that drives energy intensity down because of the declining share of this sector as the formal economy grows and as a consequence of switching to more efficient fuels less

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

decomposing the decoupling of co2 emissions and economic growth in brazil abstract this paper examines the occurrence of a decoupling between the growth rates in economic activity and co 2 emissions from energy consumption in brazil from 2004 to 2009 this decoupling was highlighted when economic activity and co 2 emissions moved in opposite directions in 2009 more generally we observe several periods of relative decoupling in brazil but not to the extent witnessed in 2009 to identify the determinants of emissions change we develop a decomposition model based on a log mean divisia index lmdi framework the results indicate that the carbon intensity and energy mix are the main determinant of emissions reduction in brazil between 2004 and 2009 modifications in the economy structure are also associated to emission mitigation in the period such evidence demonstrates similarities with events of decoupling registered for the interval 1980 1994 in brazil finds from brazil differ from observations in other countries in which improvement in energy intensity has been the most common determinant of emissions reduction

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

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

an analysis of the implications of uncertainty and agency problems on the wealth effects to acquirers of private firms abstract extensive empirical work shows that bidders do not gain from the acquisition of publicly traded targets but experience positive excess returns in the acquisition of privately held firms this study investigates how two important differences between private and public firms namely informational uncertainty and ownership characteristics impact the returns to acquirers a sample of targets that were acquired shortly after filing for an ipo was collected to circumvent the lack of information on private firms in spite of the special characteristics of these targets the listing effect is still prevalent in this sample the results of the analysis are consistent with the hypothesis that acquirers gain in the acquisition of private firms because these targets have a relatively weaker bargaining position due to informational and agency problems and costly access to external capital markets to finance growth opportunities

driving forces for aggregate energy consumption a cross country approach abstract although a cornerstone for development past and current energy use has often posed a major challenge for policymakers with respect to planning and management within this context in this paper an updated multi sectorial cross country assessment of energy consumption trends was undertaken aiming at identifying the main drivers of changes in aggregate energy consumption these drivers have been interpreted in the light of the policy measures that have been implemented over the years by different countries to achieve a sustainable development of the energy sector the cross country assessment encompasses a set of developed united kingdom portugal and spain and emerging brazil china and india countries resorting to the logarithmic mean divisia index lmdi decomposition method changes in the aggregate energy consumption were decomposed into three main explanatory effects activity structure and intensity the major findings achieved reflect the relevance of intensity and activity effects in detriment of the structural effect the assessment of energy consumption trends using the lmdi decomposition method provides critical information regarding which is the dominant factor that should be focused in policy design

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

the bright and dark side of staging investment performance and the varying motivations of private equity firms previous papers that examined investment decisions by private equity funds are divided on whether staging has a positive or negative effect on returns we believe these opposing views can be reconciled by studying when staging is used during the life of the investment relationship we find that staging has a positive effect on investment returns in the beginning of the investment relationship consistent with the notion that staging helps mitigate information asymmetry however staging appears to be negatively associated with returns when used prior to the exit decision our unique dataset allows us to measure these intertemporal effects precisely

is energy efficiency a driver or an inhibitor of energy consumption changes in spain two decomposition approaches abstract the 2000 2008 expansion period of the economy was accompanied by an important increase of energy consumption the desire of decoupling has led us to analyse the driving forces behind the energy consumption changes during this expansion period through a structural decomposition analysis sda based on the spanish input output tables previous decomposition has been supplemented by a logarithmic mean divisia index lmdi analysis of the energy consumption changes during a longer period 2000 2013 the results show that the energy intensity was the main inhibitor effect of the energy consumption changes of sectors of production not only during the recession but also during the expansion period secondly the energy intensity was a driver of the energy consumption change of households during the expansion period however during the recession period the energy intensity of private transport contributed to reducing energy consumption having an inhibitor effect therefore if the activity effect is still the most important driver the energy intensity effect has become the main inhibitor of energy consumption changes the energy policy recommendation is to focus on household energy consumption in the future if the spanish government aims to attain the eu energy efficiency objectives

intra union flexibility of non ets emission reduction obligations in the european union the eu proposal on greenhouse gas emission reduction has 28 targets for 2020 an eu wide one for co2 emissions covered by the european trading system ets and one target for non ets emissions per member state implementation is more expensive than needed i consider three alternative proposals to reduce costs in the irish proposal member states can purchase ets permits to offset excess non ets emissions in the polish proposal member states can sell excess non ets emissions in the ets in the swedish proposal member states can trade their non ets allocations i compare these alternatives to the default policy no flexibility outside the ets and the cost effective solution full flexibility i calibrate a simple model to the results of the eu impact assessment which did not disclose all details and made odd assumptions the non ets allocation exceeds the projected emissions for three member states the alternative flexibility mechanisms would be used to only a limited extent but would cut the costs of meeting the target the swedish and polish proposals come closest to the cost effective solution because of the hot air the irish proposal performs best if there are negative surprises in either abatement costs or emissions the swedish proposal will become policy

eu climate change policy 2013 2020 using the clean development mechanism more effectively in the non eu ets sector abstract under european union proposals for co 2 emission reduction between 2013 and 2020 a member state can transfer to another member state the right to use its unused clean development mechanism cdm credits the paper addresses three issues in relation to these cdm warrants cdm w first how should the member state treat the cdm w in making decisions concerning emission reduction the price of the property right is an important signal for a member state in deciding the level of domestic abatement compared to trading in cdm w s in other words a shadow price for cdm w s should be used in formulating the emission strategy in order to determine whether or not a member state is a buyer or seller of cdm w s second what mechanism should be used to facilitate the exchange of cdm w s the preferred mechanism depends on the market size over which there appears to be some ambiguity market intermediaries such as over the counter trades and exchanges are preferred if market size is small auctions if the market size is large third who should realise the value of cdm w s the state existing polluters etc the value of cdm w s should accrue to the state

economic distress financial distress and dynamic liquidation many firms emerging from a debt restructuring remain highly leveraged continue to invest little perform poorly and often reenter financial distress the existing literature interprets these findings as inefficiencies arising from coordination problems among many creditors or an inefficient design of bankruptcy law in contrast this paper emphasizes that creditors lack the information that is needed to make quick and correct liquidation decisions it can explain the long term nature of financial distress solely as the result of dynamic learning strategies of creditors and suggests that it may be an unavoidable byproduct of an efficient resolution of financial distress financial distress is often a long term process and has an impact on the capital structure investment policies and performance of many firms even after they emerge from debt restructurings james 1995 finds that many firms increase their investment expenditures only by very little in the first two years after a debt restructuring hotchkiss 1995 shows that in each of the first five years after emerging from bankruptcy between 35 percent and 41 percent of all firms have negative operating income according to gilson 1997 more than 75 percent of firms that complete debt restructurings emerge with a leverage ratio that is higher than industry median and most are still significantly more highly leveraged than before the onset of financial distress furthermore between one quarter and one third of all distressed firms

venture capital funds flow performance relationship and performance persistence this paper finds that venture capital funds that are expected to be backed by more skilled investors show no performance persistence but a significant flow performance relationship in contrast funds that are expected to be backed by less skilled investors show performance predictability and have a non significant flow performance relationship these results suggest that only skilled investors use all available information to adjust their capital allocation and as a result eliminate performance predictability as argued theoretically by berk and green 2004 results also show that kaplan and schoar 2005 overstate the persistence in fund performance by not using an ex ante measure of the performance of earlier funds whether or not an ex ante measure is used however the persistence is largely due to unsophisticated investors when investors are sophisticated the performance of earlier funds sequence and fund size do not help predict the performance of the focal fund

stagnating energy efficiency in the swedish building sector economic and organisational explanations the development towards higher energy efficiency in the swedish building sector stagnated in the late 1980s and 1990s in new buildings the average specific energy use for heating is twice as high as in the best performing buildings 20 years ago by combining econometric studies and interviews with actors in the building sector we analyse the underlying economic and organisational causes for this development in the stock of buildings specific energy use for heating kwh m2 yr has a high correlation with increasing energy prices and price elasticities have not changed markedly over time this implies that the stagnation to a large extent can be explained by energy price trends on the contrary in new buildings the correlation between energy prices and specific energy use is much weaker one important cause of low sensitivity to price changes is that information about the life cycle cost lcc of different investment alternatives is often not available to the involved actors the most common investment criterion is instead the requirements of the national building energy standard which has developed into a norm rather than a minimum for energy performance in this paper we also discuss potential improvements in the learning processes within the sector

carbon dioxide emissions intensity of portuguese industry and energy sectors a convergence analysis and econometric approach abstract given the relevance of energy and pollution issues for industrialised countries and the importance of industry and energy sectors to the achievement of their economic and environmental goals it is important to know if there is a common pattern of emissions intensity fuel intensity and energy intensity between industries to know if it justifies a more specific application of energy policies between sectors which sectors have the greatest potential for reducing energy use and which are the long term effects of those specific variables on the mitigation of emissions we found that although there is literature on decomposition of effects that affect emissions the study of the convergence and of the relationships between these variables does not include ratios or effects that result from the decomposition analysis thus the above questions are not answered much less for the portuguese reality the purpose of this paper is to study i the existence of convergence of some relevant ratios as carbon dioxide co 2 emissions intensity co 2 emissions by fossil fuel consumption fossil fuel intensity energy intensity and economic structure between industry and energy sectors in portugal and ii the influence that the consumption of fossil fuels the consumption of aggregate energy and gdp have on co 2 emissions and the influence that the ratios in which co 2 emissions intensity decomposes can affect that variable using an econometric approach namely panel corrected standard errors estimator we concluded that there is sigma convergence for all ratios with exception of fossil fuel intensity gamma convergence verifies for all ratios with exception of co 2 emissions by fossil fuel from the econometric approach we concluded that the considered variables have a significant importance in explaining co 2 emissions and co 2 emissions intensity

unravelling projected energy savings in 2020 of eu member states using decomposition analyses abstract the objective of this paper is to provide deeper insights into the energy savings efforts of eu member states by exploring the impact of new policies the recent economic recession and other effects using decomposition analyses the results of the study show that the difference between the two official eu baseline projections primes 2007 pre recession pre climate and energy package and primes 2013 post recession including the new policies of the package can be explained by the combined impact of the new policies the economic recession and other effects such as differences in energy prices however the impact of the other effects remains largely unexplained in the official primes 2013 report and is clouding the right interpretation of the policy effect by providing these insights this study could help policy makers in better understanding scenario outcomes and the impact of their policies if eu member states would be able to achieve their 2020 energy savings targets then an important step has been taken to bridge the energy savings gap since the economic recession plays a major role in bridging this gap and economic recovery is aimed for further intensification of energy efficiency policies is crucial to contribute to the ghg reduction target for 2030 and beyond

decomposition of aggregate energy intensity changes in two measures ratio and difference decomposition analysis has been popular in energy demand analysis and has been found useful in policy related studies past studies include decomposition of changes of an aggregate indicator measured in terms of either ratios or differences into several pre defined contributing factors aggregate indicators that are often studied include total national energy demand energy demand in specific consuming sectors aggregate energy intensity and energy related carbon dioxide emissions however the possible linkages between the ratio measure and the difference measure including their decomposition results have seldom been analysed this paper examines this issue using the divisia decomposition technique and a unique pair of decomposition formulae numerical examples based on singapore and taiwan industrial electricity demand data are presented

optimal leverage and aggregate investment we analyze the optimal financing of investment projects when managers must exert unobservable effort and can also switch to less profitable riskier ventures optimal financial contracts can be implemented by a combination of debt and equity when the risk shifting problem is the most severe while stock options are also needed when the effort problem is the most severe worsening of the moral hazard problems leads to decreases in investment and output at the macroeconomic level moreover aggregate leverage decreases with the risk shifting problem and increases with the effort problem

lmdi decomposition approach a guide for implementation since it was first used by researchers to analyze industrial electricity consumption in the early 1980s index decomposition analysis ida has been widely adopted in energy and emission studies lately its use as the analytical component of accounting frameworks for tracking economy wide energy efficiency trends has attracted considerable attention and interest among policy makers the last comprehensive literature review of ida was reported in 2000 which is some years back after giving an update and presenting the key trends in the last 15 years this study focuses on the implementation issues of the logarithmic mean divisia index lmdi decomposition methods in view of their dominance in ida in recent years eight lmdi models are presented and their origin decomposition formulae and strengths and weaknesses are summarized guidelines on the choice among these models are provided to assist users in implementation

imbalance in europe s effort sharing decision scope for strengthening incentives for energy savings in the non ets sectors abstract europe s 2020 greenhouse gas ghg reduction target consists of two sub targets one for the emissions trading scheme ets sectors and one for the non ets sectors the non ets target covers co 2 emissions in buildings transport and non ets industry and non co 2 ghg emissions the non ets target is known as europe s effort sharing decision this article discusses the gdp per capita method the european commission has applied in setting member state specific targets for the non ets the effort sharing and shows that it results in an imbalanced reduction effort among the member states it turns out that the principal mechanism of the gdp per capita method low gdp countries get room to catch up with high gdp countries by allowing them to increase emissions is obscured by the non co 2 ghgs the baseline projections of which are highly policy induced and not correlated with the growth of gdp per capita we propose an alternative method that 1 corrects for the policy induced decrease of non co 2 ghg emissions and 2 is based on energy savings potentials this approach could be used in future target setting for non ets sectors including in the case that the overarching eu wide target would be strengthened and would provide a direct support to europe s energy savings ambitions and policies

ipos trade sales and liquidations modelling venture capital exits using survival analysis using a detailed sample made up of more than 20 000 investment rounds we analyze the time to ipo trade sale and liquidation for about 6 000 venture backed firms we model these exit times using competing risks models biotech and internet firms have the fastest ipo exits internet firms are also the fastest to liquidate while biotech firms are however the slowest the conditional probability for ipos are clearly non monotonous with respect to time as time flows venture capital backed firms first exhibit an increased likelihood of exiting to an ipo however after having reached a plateau investments that have not yet exited have fewer and fewer possibilities of ipo exits as time increases the bubble period from 1998 to 2000 was an easy money period where venture capitalists gave much more money to firms many of which did not offer outstanding growth potential as they tended to liquidate much faster than in normal times

why hang on to losers divestitures and takeovers we study the divestiture decisions of managers who care about their reputations managers divestiture and investment decisions are publicly observable but managers privately observe signals with respect to the future payoff distribution of investments they have initiated we establish that in equilibrium there is too little divestiture these inefficiencies create the opportunity for wealth enhancing divestiture motivated takeovers a key result is that only managers of targets with middle of the road asset specificity should consider the takeover threat credible these findings suggest that uniqueness of assets is an important determinant of both agency costs and takeover activity our analysis leads to several empirical predictions overwhelming empirical evidence has documented large gains in shareholder wealth that arise from takeovers jarrell brickley and netter 1988 and jensen and ruback 1983 the source of these gains has remained elusive however although takeovers are followed by some infusion of new managerial talent we have not witnessed the kind of profound post takeover restructuring of the productive activities of target firms that would readily justify the documented wealth gains a commonly observed post takeover initiative is divestiture of some of the target s lines of business bhide 1989 and bhagat shleifer and vishny 1990 what is puzzling is that if the gains from takeovers stem from the anticipation of such divestitures then why were these divestitures not undertaken by the target firm s management in the first place the purpose of this paper is to provide a possible answer to this question our focus is on the divergence in incentives between managers and shareholders with respect to divestitures of ongoing projects we show that managers might rationally decide to hang on to projects that should be divested in

spillovers from publicly financed r d capital in high tech industries abstract this paper employs a dynamic production model to examine the short run effects of publicly financed r d capital on the cost structure of six high tech us manufacturing industries the results show that given an industry s output publicly financed r d capital reduces the variable production cost in all industries in addition an increase in publicly financed r d causes output to increase implying that producers as well consumers are better off despite the presence of strong monopoly power in some industries a low bound for the social rate of return to publicly financed r d is also calculated
