interactions between renewable energy policy and renewable energy industrial policy a critical analysis of china s policy approach to renewable energies this paper analyzes china s policy approach to renewable energies and assesses how effectively china has met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy first we briefly discuss the interactions between these two policies then we outline china s key renewable energy and renewable industrial policies and find that china s government has well recognized the need for this policy interaction after that we study the achievements and problems in china s wind and solar pv sector during 2005 2012 and argue that china s policy approach to renewable energies has placed priority first on developing a renewable energy manufacturing industry and only second on renewable energy itself and it has not effectively met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy lastly we make an in depth analysis of the three ideas underlying this policy approach that is the green development idea the low carbon leadership idea and indigenous innovation idea we conclude that chinas policy approach to renewable energies needs to enhance the interactions between renewable energy policy and renewable energy industrial policy the paper contributes to a deeper understanding of china s policy strategy toward renewable energies

nonmonetary effects of the financial crisis in propagation of the great depression this paper examines the effects of the financial crisis of the 1930s onthe path of aggregate output during that period our approach is complementary to that of friedman and schwartz who emphasized the monetary impact of the bank failures we focus on non monetary primarily credit related aspects of the financial sector output link and consider the problems of debtors as well as those of the banking system we argue that the financial disruptions of 1930 33 reduced the efficiency of the credit allocation process and that the resulting higher cost and reduced availability of credit acted to depress aggregate demand evidence suggests that effects of this type can help explain the unusual length and depth of the great depression this abstract was borrowed from another version of this item

financial intermediary coalitions abstract in this article an environment in which the investment opportunities of agents are private information is studied and it is shown that financial intermediaries arise endogenously within that environment it is established that financial intermediaries are part of an efficient arrangement in the sense that they are needed to support the authors private information core allocations these intermediaries which are coalitions of agents exhibit the following characteristics in equilibrium they borrow from and lend to large groups of agents they produce information about investment projects and they issue claims that have different state contingent payoffs than claims issued by ultimate borrowers

assessing the system and investor value of utility scale solar pv abstract with pressure to reduce greenhouse gas emissions from the energy and other sectors policymakers are increasingly seeking to mobilise investment in renewable electricity with support mechanisms the objective of this paper is to assess the value of utility scale solar pv using a multidisciplinary approach in many cases renewable energy strategies are developed by investors and policymakers on the basis of a relatively narrow analysis of costs however as policies should be designed to maximise societal welfare a wider paradigm is needed in decision making this paper argues for an impact assessment of renewable electricity generation that integrates its value from investor utility policy maker and end user perspectives we propose a multidisciplinary approach to the assessment combining engineering production cost estimation with financial and market analysis of utility scale solar pv in ireland the results show that while from an investor s perspective solar pv generation is and will likely remain so for the foreseeable future relatively expensive in a country with low solar irradiation such as ireland there are benefits for the electricity system in terms of reduced wind curtailment and to a lesser extent co2 emissions this demonstrates why the wider costs and benefits of integrating a renewable electricity technology to the system need to be considered in assessment of renewable policy support mechanism policy makers can then seek to maximise the system benefits while minimising the cost of any policy supports

lessons from photovoltaic policies in china for future development abstract the paper first provides an overview of the current status of pv industry development in china including the penetration speed the market segments and the value chain further it reviews the experience of governmental interventions composed of the legal framework market incentives and manufacturing policies for lessons learning after the renewable energy law took effect in 2006 pv penetration was accelerated capital subsidies and feed in tariffs which were still in a trial stage public bidding and the cooperation among relevant ministries played important roles a series of public rd the budget and the organization of public pv r d were insufficient finally we propose some recommendations on improving policy interventions

demand pull technology push and government led incentives for non incremental technical change abstract rising expectations about future demand for new technologies increase the incentives for investments in innovation by enlarging payoffs to successful innovations how well does this notion of demand pull apply to non incremental technological change when demand is largely attributable to actions by governments in this case inventors of the most important inventions did not respond positively to strong demand pull policies filing of highly cited patents declined precipitously just as demand for wind power created a multi billion dollar market three explanations for this apparent inconsistency with the demand pull hypothesis played a role 1 the rapid convergence on a single dominant design limited the market opportunity for non incremental technical improvements 2 even though the policies implemented were stringent enough to stimulate demand uncertainty in their longevity dampened the incentives for inventions that were likely to take several years to pay off and 3 alternative explanations such as declining r d funding and weakening presidential engagement on energy appear to have been important

changing sunshine analyzing the dynamics of solar electricity policies in the global context abstract although solar costs have been dropping in recent years solar power is still more expensive than conventional and other renewable energy options and in most applications solar power still needs continuing government policy support however the need to achieve multiple objectives and ensure sufficient political support for solar power makes it difficult for policy makers to design an optimal solar power policy the dynamic and uncertain nature of the solar industry combined with the constraints imposed by broader economic political and social conditions further complicates the task of policy making in this paper we present a framework to critically analyze the objectives behind different country policies how factors such as macro economic conditions and development paradigms affect the policy outcomes and finally how these outcomes affect the overall cost reduction of solar energy we find that while the extent of cost reduction through creation of large demand remains to be seen it is essential for governments to provide adequate support for leapfrog rd d and exploit real comparative advantages across countries for effective solar cost reduction policy makers need to optimally design their policies by balancing national objectives and paying capacity with the global objective of solar power cost reduction in order to realize its full potential

rat race redux adverse selection in the determination of work hours in law firms this paper describes an organizational setting in which professional employees are required to work inefficiently long hours the focus of the authors investigation is large law firms the income sharing that characterizes legal partnerships creates incentives to promote associates who have a propensity to work very hard law firms use indicators of this propensity especially an associate s record of billable hours in promotion decisions reliance upon work hours as an indicator leads to a rat race equilibrium in which associates work too many hours the authors find evidence in support of this conclusion with data they collected from two large law firms copyright 1996 by american economic association

exploring china s carbon emissions peak for different carbon tax scenarios abstract under the united nations framework convention on climate change china has made a commitment to peak co2 emissions around 2030 china is still interested in fulfilling its commitment to address climate change in this study a diffusion model of energy technology based on endogenous technology learning under bounded rationality is developed to explore the possible impacts of different carbon tax conditions on the diffusion of energy technologies in china it is concluded that the substitution of energy technology is a long term and slow process in the case of a high carbon tax transition technologies and new technologies will appear earlier and replace the original technology 6 8 years earlier than in the case of a lower carbon tax the transition technology will become dominant only for a short period of time around 2030 but will be quickly replaced by new technology the traditional technology will cease to exist in the last thirty years of this century in all carbon tax scenarios in the low carbon tax or high carbon tax scenarios carbon emissions will peak in 2030 and then decline significantly the peak in carbon emissions is lower under the high carbon tax scenario than the low carbon tax scenario representing a 28 decrease

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

fiscal trends in real economic aggregates using cointegration analysis the authors examine long term interactions between fiscal variables and the consumption output and leisure labor ratios the motivation is to test if fiscal trends are an independent source of stochastic trends underlying the long run behavior of real economic aggregates the authors results support the presence of fiscal trends and can be interpreted quite well in terms of the equilibrium approach to fiscal policy they suggest that neoclassical growth models that embed fiscal trends and distinguish between components of government purchases are more consistent with the data than simple real business cycle models copyright 1995 by ohio state university press

analysis of the policy effects of downstream feed in tariff on china s solar photovoltaic industry abstract the chinese government initiated the feed in tariff fit policy for downstream power generation in august 2013 the effectiveness of the downstream fit policy has attracted the attention of academia and government using the quarterly data of listed solar pv companies between 2009 and 2015 this paper provides an empirical analysis regarding the effects of the downstream fit policy we find that 1 the fit policy has significantly enhanced the inventory turnover of listed pv firms and improved their profitability 2 the fit policy has significant effects on the inventory turnover of midstream companies and mixed industry chain companies mainly engaged in downstream operations 3 fit policy is more favorable towards increasing the inventory turnover of private enterprises our results indicate that the fit policy can have substantial effects on the sustainable development of china s solar photovoltaic industry

an innovation management approach for renewable energy deployment the case of solar photovoltaic pv technology abstract in the discussion of renewable energy deployment one key concern is the various types of barriers that renewable energy needs to overcome before it can make its way into the mainstream these barriers increasingly shift from the technical to the economic and institutional the most general types of barriers are due to technological lock out or to carbon lock in unruh g 2000 understanding carbon lock in energy policy 28 12 817 830 elsevier these barriers necessitate the development of a strategic approach to deploy or introduce renewable energy technology existing energy policy has mostly relied upon financial subsidies market based instruments such as renewable portfolio standards and production tax credits to stimulate the installation and use of equipment to generate electricity from renewable sources these strategies target mostly system level decisions of end users the purpose of this paper is to present an innovation perspective on the renewable energy deployment process by introducing the innovation value added chain ivc framework the analytical objective of ivc is to evaluate the impact of a new innovation on the various stakeholders and players in the development and deployment processes a deployment or innovation strategy that causes minimal disruption enhances existing competencies or expedites new learning by the players has a higher chance to succeed we draw upon two sets of system integration costs data for grid connected distributed photovoltaic pv systems in japan and the united states and demonstrate conspicuously different dynamic learning behaviors these two deployment models can be understood in terms of how the ivcs are organized and how pv system integration projects are performed in the field in addition ivc based findings can inform the targeted application of conventional financial subsidies for learning investment not only at the pv system level but also at the localized system integration level this would involve other stakeholders thus suggesting new energy policy space we highlight some future research directions using the ivc framework

dynamic effects of financial intermediation over the business cycle ping wang this paper provides a empirical evidence that the financial intermediation disturbances can generate business cycles we examine three countries whose financial sectors are fully developed but quite distinct in their institutional and regulatory circumstances thus we can infer whether financial intermediation disturbances differ across dissimilar financial environments we find that the dynamic responses of output to financial intermediation shocks exhibit similar patterns in all cases studied however the various institutional and regulatory circumstances have generated different propagation mechanisms transmitting the financial disturbance to output in ways that lead the magnitudes of the responses to deviate across economies jel e32 e44 i introduction does the financial sector veil the real economy although some economists such as lucas 1988 argue that financial factors are over stressed there is a growing literature that theoretically cultivates the channels through which financial intermediation can influence economic fluctuations and long run growth rather than focus on the traditional monetary transmission mechanism this literature plants itself in the microfoundations of asymmetric information and contract theory the new financial intermediation literature stems from seminal works by diamond 1984 townsend 1983a 1983b and boyd and prescott 1986 that demonstrate that in the presence of private information and costly state verification it is optimal for borrowing and lending to be conducted under financial intermediary arrangements these ideas were then extended by williamson 1987 to show how disturbances in the financial intermediation sector can generate business cycle fluctuations essentially when investment projects become more risky or difficult to evaluate loan supply falls and business cycle movements emerge 1 moreover other financial intermediation impulses are likely to be important as well these include changes to the institutional framework or the regulatory environment and any other event that enhances or hinders the intermediaries capacity to allocate capital efficiently among competing alternative uses e g financial innovation yet despite the theoretical rhetoric on the importance of financial intermediation to output fluctuations the empirical relevance of financial intermediation remains an unsettled question this paper brings us one step closer to the solution by econometrically identifying structural financial intermediation disturbances and estimating their effect on output movements in three major industrialized countries germany the united kingdom and the united states we choose these three advanced economies not only because their financial sectors are fully developed but also because their distinct banking structures and regulatory environments are capable of generating and transmitting financial intermediation disturbances in different ways that is the depth of financial intermediation is relatively similar across countries therefore the cross country analysis allows us to focus on the ability of financial intermediation to generate short run cycles and to draw some suggestive insights regarding the role of regulatory and institutional factors across countries the existing empirical evidence linking financial factors to real economic activity has involved noticing statistical correlations between some financial variables and some real variables goldsmith 1969 using data from 1860 to 1963 showed that there is a positive relationship between economic development and the size of the financial sector kuznets 1971 in a cross section study of 57 developed and developing economies found that the share of banking insurance and real estate in gross domestic product rises as income increases mckinnon 1973 showed that the ratios of private credit to national income and a broad monetary aggregate to national income are positively related to per capita income

quantitative study on long term global solar photovoltaic market abstract this paper analyzes the relationship between the declines in solar photovoltaic pv module costs and cumulative production silicon prices supply demand imbalance and the presence of lower cost chinese products in global pv market using learning curve model state of market development and its connection with learning is also examined results indicate that learning effect is best measured when supplementing output with silicon prices in the analysis learning rate lr diminishes over the time periods examined thereby suggesting the declining of progress as market reaches maturity the outcomes from the learning curve analysis are subsequently applied to project future uptake of pv worldwide module and electricity costs till 2035 demand for pv is anticipated to remain robust with cumulative installed capacity worldwide projected to reach 659 gw by 2035 at the same time module cost is estimated to decline from 3 8 w in 2006 to 1 78 w in 2035 a reduction of over 50 relative to 2006 level unit cost of electricity from pv is predicted to be in the range of 0 13 kwh to 0 17 kwh by 2035 for the three scenarios analyzed

co2 abatement from renewables in the german electricity sector does a co2 price help abstract the overlapping impact of the emission trading system ets and renewable energy re deployment targets creates a classic case of interaction effects whereas the price interaction is widely recognized and has been thoroughly discussed the effect of an overlapping instrument on the abatement attributable to an instrument has gained little attention this paper estimates the actual reduction in demand for european union allowances that has occurred due to re deployment focusing on the german electricity sector for the five years 2006 through 2010 based on a unit commitment model we estimate that co 2 emissions from the german electricity sector are reduced by 35 to 60 mtons or 10 to 18 of what estimated emissions would have been without any re policy but with the co 2 price remaining in place at the observed level furthermore we find that the abatement attributable to re injections is greater in the presence of an allowance price than otherwise the same holds for the ets effect in presence of re injection this interaction effect is consistently positive for the german electricity system at least for the considered years and on the order of 0 5 to 1 5 of emissions

cost and co2 reductions of solar photovoltaic power generation in china perspectives for 2020 abstract to improve the understanding of the cost and benefit of photovoltaic pv power generation in china we analyze the per kwh cost fossil energy replacement and level of co2 mitigation as well as the cost per unit of reduced co2 of pv power generation in 2020 at the province level three potential pv systems are examined large scale pv lspv building integrated pv bipv and distributed pv systems used in remote rural areas which have very low capacities the results show that in 2020 pv power generation could save 17 4 mtce fossil energy and 46 5 tg co2 compared with 600 mwe coal fired supercritical units also in 2020 the costs of solar electricity could be reduced by approximately 60 as compared to 2010 but would still be 11 74 higher than the current grid prices the pv electricity costs vary significantly among provinces in the economically developed eastern provinces the pv electricity mainly bipv is 0 67 0 86 rmb kwh this rate is close to grid parity owing to high grid prices but the co2 mitigation cost is high 456 693 rmb mg co2 the pv electricity mainly lspv in solar resource rich western provinces has lower cost 0 45 0 75 rmb kwh and lower co2 mitigation cost 172 419 rmb mg co2 but is farther from grid parity due to the low local grid price from a cost effective perspective lspv in the west provinces should be the first priority in pv deployment strategies and should receive strong financial support from the government this study provides a quantitative province specific analysis of pv power generation which can be used to support various pv subsidy policies

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

estimating the co2 abatement cost substitute price of avoiding co2 emission spae by renewable energy s feed in tariff in selected countries abstract many renewable energy policies are looking into new incentives to absorb investments by targeting abating co 2 emission and fixing energy price fluctuation feed in tariff fit is a policy for rebating the amount of generated renewable electricity to investor fit is also defined as a co 2 mitigation policy in electricity generation from renewable sources this paper presents a cost benefit survey that estimates the real produced carbon dioxide for electricity generation in selected countries this study introduces the substitute price of avoiding co 2 emission as an indicator the new indicator shows how much is paid for avoiding co 2 by each selected countries through the fit policy for renewable technologies the amount calculated for solar energy is taken as a case in this paper the result confirms that the fit policy reasonably works for solar energy in absorbing investment however the fit policy claims a large portion of liquidity compared with other approaches hence makes this mechanism inept as a co 2 mitigation policy

solar energy markets economics and policies abstract solar energy has experienced phenomenal growth in recent years due to both technological improvements resulting in cost reductions and government policies supportive of renewable energy development and utilization this study analyzes the technical economic and policy aspects of solar energy development and deployment while the cost of solar energy has declined rapidly in the recent past it still remains much higher than the cost of conventional energy technologies like other renewable energy technologies solar energy benefits from fiscal and regulatory incentives including tax credits and exemptions feed in tariff preferential interest rates renewable portfolio standards and voluntary green power programs in many countries the emerging carbon credit markets are expected to provide additional incentives to solar energy deployment however the scale of incentives provided by the existing carbon market instruments such as the clean development mechanism of the kyoto protocol is limited despite the huge technical potential the development and large scale deployment of solar energy technologies world wide still has to overcome a number of technical financial regulatory and institutional barriers the continuation of policy supports might be necessary for several decades to maintain and enhance the growth of solar energy in both developed and developing countries

work hours regulation in a search economy with adverse selection abstract two arguments for introducing a maximum work hours regulation are to enhance workers welfare by limiting excessive hours of work and to increase employment through work spreading we analyze the effects of this regulation in a labor market where adverse selection is an issue our results suggest that this policy would in fact reduce unemployment and worked hours but it would also reduce the welfare of affected workers and aggregate welfare this happens because in the new equilibrium wages are reduced and entry by firms is excessive we obtain our results in a two type competitive search model with adverse selection a la guerrieri et al 2010

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

comprehensive effectiveness assessment of renewable energy generation policy a partial equilibrium analysis in china abstract in order to stimulate renewable energy and control carbon dioxide emissions the chinese government has already introduced lots of renewable energy generation policies under this background it is of great significant to figure out the economic environmental and social effectiveness of these polices firstly this paper systematically studied the framework and content of renewable energy generation policies secondly this paper built a basic partial equilibrium model to calculate the equilibrium state of electricity market and carbon emissions on this base the effectiveness of seven renewable energy generation policies was analyzed by introducing policies into the basic model and comparing relevant indicators in different policy scenarios with that in basic scenario further an empirical analysis was made to estimate the actual benefits of these policies in china this paper proposed an analysis method for evaluating the mechanism effectiveness and efficiency of renewable energy generation policies all the results and discussions in this paper can provide specific suggestions for chinese government to shape a blueprint for implementing different kinds of policies

u s energy research and development declining investment increasing need and the feasibility of expansion investment in energy research and development in the u s is declining despite calls for an enhancement of the nation s capacity for innovation to address environmental geopolitical and macroeconomic concerns we examine investments in research and development in the energy sector and observe broad based declines in funding since the mid 1990s the large reductions in investment by the private sector should be a particular area of concern for policy makers multiple measures of patenting activity reveal widespread declines in innovative activity that are correlated with research and development r d investment notably in the environmentally significant wind and solar areas trends in venture capital investment and fuel cell innovation are two promising cases that run counter to the overall trends in the sector we draw on prior work on the optimal level of energy r d to identify a range of values which would be adequate to address energy related concerns comparing simple scenarios based on this range to past public r d programs and industry investment data indicates that a five to ten fold increase in energy r d investment is both warranted and feasible

can carbon pricing support onshore wind power development in china an assessment based on a large sample project dataset abstract there is much discussion about whether the rapid expansion of onshore wind power in china is sustainable given the decrease in feed in tariffs fit it is unclear whether the recently launched nationwide carbon pricing system which will include 1700 power companies can compensate for decreasing fits and possibly provide new incentives for wind power developments this paper investigates the ability of carbon pricing policies to compensate for declining fits in support of onshore wind power investment in china first we constructed a dataset of 2059 onshore wind power projects from china s thirty provinces between 2006 and 2015 to estimate the levelized costs of electricity lcoe this dataset was used to assess the profitability of each wind project for different carbon prices varying levels of fits curtailment rate and discount rate our findings suggest that the carbon price can compensate partially for the revenue loss caused by declining fits as well as improving the profitability of projects however current carbon prices in china s carbon emission trading pilots are not sufficiently high to compensate for the revenue losses especially under the grid parity scenario consequently without fits the sustainable development of onshore wind power in china is uncertain a sensitivity analysis of the effect of the carbon pricing policy demonstrates that in the case of higher investment risk and more serious curtailment the effect of carbon pricing policy on promoting the wind power investment seems to be more significant

trend analysis of energy and climate policy environment comparative electricity production and consumption benchmark analyses of china euro area european union and united states abstract this study conducts a reality check on the electricity production and electricity consumption trends in china in the u s and in the euro area and in the eu most of our analyses cover years 1961 2011 the data is based on the world bank s database with supplementary iea database 2013 in this article we perform various trend analyses which are linked to electricity production and consumption developments these regions are major players in global climate change and climate policy our trend analyses indicate in many ways that china is now a global trend setter in climate change and climate policy upwards sloping trends were evident in the chinese energy economy however u s and the eu are still very important players trend analyses of this article indicate that the structures of electricity production and energy mixes are changing our benchmarking studies indicate that the role of renewables is increasing in electricity production and the role of oil based electricity production has drastically decreased the golden age of nuclear energy in electricity production seems to be over at least turning points can be found in trend developments empirical trade off analyses of the study verified conventional research results about high linear correlation coefficients regression models between electricity production and gdp as well as between population and gpd in all regions correlation coefficients measure the strength of association between two variables what was interesting is that our comparative analyses revealed some remarkable differences in linear regression equation coefficients one of them was that the coefficient between population and electricity production is much lower in china than in the u s or in the eu second finding was that the coefficient of the regression model describing linear relationship between gdp and electricity production is highest in china in comparison to the other regions

cost of power or power of cost a u s modeling perspective abstract future scenarios and assessment studies used to prepare for long term energy transitions and develop robust strategies to address climate change are highly dependent on the assessment of technology characteristics and availability the electric power sector in the united states recently experienced a significant cost escalation e g construction costs for large plants such as nuclear and coal fired power plants doubled between 2003 and 2007 we assess the main drivers of this escalation while many factors have affected costs some of the most significant include cost of materials particularly the price of metals and to a lesser extent cement possible increases in labor quantity requirements the aggressive worldwide competition for power plant design and construction resources driven by high demand in asia market and regulatory changes and general uncertainty about future regulations and climate policies we recalibrate power sector technology costs in the global change assessment model gcam based on an extensive literature review of recent post 2010 studies and in the process develop a coherent and updated set of current cost and performance assumptions for all major electricity generating technologies while current cost and performance assumptions of electricity generating technologies are key drivers of short term technology deployment and technology mix in the electricity sector medium and long term deployment pathways are significantly affected by assumed efficiency improvement rates and cost reductions we develop and demonstrate a method to project efficiency and construction cost of power plants and report a sensitivity analysis to explore the importance of such assumptions in future scenarios generated by gcam

measuring the progress and impacts of decarbonising british electricity abstract britain s ambitious carbon targets require that electricity be immediately and aggressively decarbonised so it is reassuring to report that electricity sector emissions have fallen 46 in the three years to june 2016 their lowest since 1960 this paper analyses the factors behind this fall and the impacts they are having the main drivers are demand falling 1 3 per year due to efficiency gains and mild winters gas doubling its share to 60 of fossil generation due to the carbon price floor and the dramatic uptake of wind solar and biomass which now supply up to 45 of demand accounting conventions also play their part imported electricity and biomass would add 5 and 2 to emissions if they were included the pace of decarbonisation is impressive but raises both engineering and economic challenges falling peak demand has delayed fears of capacity shortage but minimum net demand is instead becoming a problem the headroom between inflexible nuclear and intermittent renewables is rapidly shrinking with controllable output reaching a minimum of just 5 9 gw as solar output peaked at 7 1 gw 2015 also saw britain s first negative power prices the highest winter peak prices for six years and the highest balancing costs

employment and distributional effects of restricting working time we study the employment and distributional effects of regulating reducing working time in a general equilibrium model with search matching frictions job creation entails fixed costs but existing jobs are subject to diminishing returns we characterize the equilibrium in the de regulated economy where firms and individual workers freely negotiate wages and hours then we consider the effects of a legislation restricting the maximum working time while we let wages respond endogenously employment effects are sensitive to the representation of preferences in our benchmark small reductions in working time starting from the laissez faire equilibrium solution always result in a small increase in the equilibrium employment while larger reductions reduce employment the regulation benefits workers both unemployed and employed even if wages decrease and even in cases where employment falls but reduces profits and output

financial structure and economic activity a recent development in economic science is the attempt to integrate monetary theory with the theory of general economic equilibrium this work takes as its starting point the idea that money cannot have value in standard general equilibrium models in these too much trade can be accomplished in centralized markets see robert clower 1969 1971 frank hahn 1973 or neil wallace 1980 thus to decentralize or break up the structure either exchange must be made costly or there must be restrictions on who can trade with whom and thus such choicetheoretic models offer the intriguing possibility that real and monetary phenomena can be understood as intimately related this paper continues in the relatively brief choice theoretic tradition motivated by real and monetary phenomena associated economic development and growth 1 to be noted first is simon kuznets seminal work on national income 1971 in a cross section study of fifty seven countries in 1958 kuznets shows that the share of the agricultural sector including forestry fishing and hunting in gross domestic product is inversely correlated with gross domestic product per capita the share of the industrial sector including transportation and communication is closely and positively associated with per capita product the share of the service sector tends to be positively but weakly associated with per capita product but the share of banking insurance and real estate shows a striking rise as one shifts from lowto higher income countries moreover the evidence suggests that the ratio of industrial prices to agricultural prices is perhaps lower the higher is per capita income though the evidence on relative prices for the service sector is inconsistent turning to long time series for thirteen developed and four less developed countries kuznets finds dramatic evidence for a decline of the agricultural sector and a rise in the industrial sector with per capita income at least in developed countries again results for the service sector are mixed but canada france and the united states are positive exceptions the share of a transport communication subsector rises quite consistently turning next to shares of sectors in the labor force kuznets finds both on a cross sectional and secular basis that all the above movements are at least mirrored and in many cases amplified in particular both components of the share of the service sector services and commerce rise substantially with gross domestic product per capita 2 to be noted second is the extensive work of raymond goldsmith on financial structure and financial intermediation for the united states goldsmith 1958 finds that the activity of intermediaries as measured by their share in national assets in tangible assets and in all claims has shown a substantial rise from 1860 to 1952 similarly goldsmith 1969 finds that the ratio of financial institutions assets to gross national product rises substantially from 1860 to 1963 in both developed and less developed countries including switzerland great britain the united states japan argentina and india related the number of households with savings accounts the number with life insurance policies and the number with stock ownership expressed as percents of the population are all low for less developed countries relative to developed countries and professor of economics carnegie mellon university graduate school of industrial administration schenley park pittsburgh pa 15213 this paper was motivated by a conversation with thomas sargent and has been aided by helpful comments from robert barro robert e lucas jr dan peled kenneth singleton and neil wallace financial support from the national science foundation the alfred p sloan foundation and the peterkin symposium on foundations of monetary policy and government finance at rice university and research assistance from pramerudee townsend are all gratefully acknowledged i alone assume full responsibility for any errors and for the views expressed here

the analysis on photovoltaic electricity generation status potential and policies of the leading countries in solar energy abstract energy which is the main agenda of our world is crucially important for the people many countries frequently held meetings and discussions with energy agenda these countries are working to balance the energy demand and supply for finding the solution are researched researches should be attempted to present a more efficient way to use energy as well as renewable energy resources effectively photovoltaic energy power systems take place as the most dominant source among renewable energy technologies the most important reason is that it is unlimited and clean energy of the solar power systems many studies show that photovoltaic power systems will have an important share in the electricity of the future in this study to generate electricity from solar energy using photovoltaic systems have a leading position in some european countries united states of america china and japan s current status and future policies will be analyzed in various comments were made

going green trade specialisation dynamics in the solar photovoltaic sector abstract the present study aims at providing a comprehensive analysis of trade flows and the domestic value creation of the major solar photovoltaic industry at the world level solar technologies convert light and heat from the sun into useful energy the use of the sun s energy can not only reduce the consumption of conventional fuels thus reducing the emission of detrimental greenhouse gases but it can also enable a gain in enhanced fuel and energy security along with lessening costs in addition green technologies and industries can promote economic growth and international competitiveness and can offer new business and employment opportunities it becomes therefore extremely important to deeply explore the dynamics of the solar photovoltaic sector specifically the present work analyses the main global trends of this sector and sketches the key players on the world market including producers installers and top traders based on an analysis of trade flows at the 6 digit level the international specialisation patterns are investigated and the role of various market and trade drivers including subsidies in the uptake of solar technologies is identified and examined

fostering a renewable energy technology industry an international comparison of wind industry policy support mechanisms this article examines the importance of national and sub national policies in supporting the development of successful global wind turbine manufacturing companies we explore the motivations behind establishing a local wind power industry and the paths that different countries have taken to develop indigenous large wind turbine manufacturing industries within their borders this is done through a cross country comparison of the policy support mechanisms that have been employed to directly and indirectly promote wind technology manufacturing in 12 countries we find that in many instances there is a clear relationship between a manufacturer s success in its home country market and its eventual success in the global wind power market whether new wind turbine manufacturing entrants are able to succeed will likely depend in part on the utilization of their turbines in their own domestic market which in turn will be influenced by the annual size and stability of that market consequently policies that support a sizable stable market for wind power in conjunction with policies that specifically provide incentives for wind power technology to be manufactured locally are most likely to result in the establishment of an internationally competitive wind industry

location matters the impact of renewable power on transmission congestion and emissions abstract many governments offer subsidies for renewable power to reduce greenhouse gas emissions in the power sector however most support schemes for renewable power do not take into account that emissions depend on the location of renewable and conventional power plants within an electricity grid i simulate optimal power flow in a test grid when 4 renewable power plants connect to the grid across 24 potential sites amounting to over 10 000 configurations each configuration is associated with different levels of emissions and renewable power output i find that emission reductions vary by a factor of 7 and that curtailment due to transmission congestion is more likely when renewable power plants are concentrated in an area of the grid with low demand large cost savings could be obtained by allowing subsidies for renewable power to vary across locations according to abatement potential or by replacing subsidies with a price on emissions

econometric modeling of co2 emissions abatement comparing alternative approaches abstract as investments and policies that promote renewable energy re projects in electricity systems are most often grounded on the goal of reducing emissions of greenhouse gases and actual investment and policy decisions are shaped by the estimates of the accrued emissions savings it is crucial that these estimates are as accurate as possible in this paper we compare different econometric models that estimate the amount of carbon abated due to re in terms of their results and their inherent methodological benefits and drawbacks specifically we use the british french and spanish grids as case studies for the application of a selection of econometric models and compare the resulting co2 abatement estimates we find that across the three markets estimates can vary substantially across the different models this can lead to an over or underestimation of the emissions abated by re overall our results highlight the need for choosing econometric specifications that lead to results that are congruent with the operational framework of the examined power systems

the costs of charging plug in electric vehicles pevs within day variation in emissions and electricity prices abstract the social costs of charging plug in electrical vehicles pevs that vary by times of day and by levels of emissions in electricity production are investigated using data available for the sacramento area in the united states for 2013 we estimate marginal emission rates of electricity and marginal price of electricity provided for charging pevs at different times of the day as the marginal emission rates and wholesale electricity price have different daily patterns there is a trade off between emission and charging cost moreover the estimates in the literature of the social costs for the most important emission co2 vary substantially implying that the social cost of charging pevs vary with the assumed cost simulations show that the charging time of lowest social costs for pevs is found to be at midnight if the social cost of co2 is not very high
