the determinants of dismissals quits and layoffs a multinomial logit approach in efficiency wage models workers productivity depends positively on the wage giving firms an incentive to pay wages above their market clearing level two models in this literature are the shirking model of shapiro and stiglitz 12 and bowles 1 and the turnover cost model of stiglitz 13 schlicht 11 and salop 10 in the shirking model a higher wage and a higher unemployment rate raise the cost of losing one s job thereby discouraging workers from shirking and increasing their effort in the turnover cost model a higher wage reduces quits and thus lowers the firm s cost of hiring and training new workers given the role of separations in efficiency wage models it is important to understand the determinants of separations this study uses data on individual workers to examine the determinants of dismissals quits and layoffs within the first six months of a hire paying particular attention to dismissals because of the prominence of the shirking model in the efficiency wage literature the purposes of this study are to test whether higher unemployment lowers dismissals as predicted by the shirking model and to examine the effect of firm variables related to the costs of monitoring and shirking on the probability of a dismissal in addition this study provides insight into the effects of firm characteristics and worker characteristics on dismissals quits and layoffs

union power cost of job loss and workers effort the authors hypothesize that the effectiveness of external threats in raising workers effort is mediated by among other labor market conditions the presence or absence of a powerful union in particular they argue that because powerful unions reduce the potency of the external threat of job loss by making it more difficult for employers to dismiss workers the pace of work is less responsive to such a threat in strongly unionized plants than in weakly unionized plants the results of an analysis of data from the 1990 workplace industrial relations survey in britain support this hypothesis the analysis also yields evidence that effort is increased where workers are rewarded individually according to results and where there are various communication channels between workers and management

an institution based view of international business strategy a focus on emerging economies leveraging the recent research interest in emerging economies this perspective paper argues that an institution based view of international business ib strategy has emerged it is positioned as one leg that helps sustain the strategy tripod the other two legs consisting of the industry and resource based views we then review four diverse areas of substantive research 1 antidumping as entry barriers 2 competing in and out of india 3 growing the firm in china and 4 governing the corporation in emerging economies overall we argue that an institution based view of ib strategy in combination with industry and resource based views will not only help sustain a strategy tripod but also shed significant light on the most fundamental questions confronting ib such as what drives firm strategy and performance in ib

energy efficiency and productivity change of china s iron and steel industry accounting for undesirable outputs abstract this paper used data from 50 enterprises in china s iron and steel industry to evaluate their energy efficiency and productivity change the study first used a conventional data envelopment analysis model and the malmquist productivity index mpi to measure the energy efficiency and productivity change over the period 2001 2008 the results indicated inefficiency in many of the plants the average energy efficiency was only 61 1 the annual growth rate of productivity was 7 96 over this period and technical change was the main contributor to this growth the research then took undesirable outputs into consideration by using the malmquist luenberger productivity index mlpi to explore the productivity change from 2006 to 2008 omitting undesirable outputs would result in biased efficiency change and technical change this paper also claimed that environmental regulation has a potentially positive impact on technical change

efficiency wages interfirm comparison and unemployment the paper presents an efficiency wage model where worker effort depends on own wages relative both to wages of other workers in the firm and to similar workers in other firms first we show how the solow conditions are modified if internal comparison effects are at work second we discuss the effect of internal wage comparison on wage inequality within firms third we study unemployment and relative wage determination within a general equilibrium model and analyze the effect of technological change and various tax policies on equilibrium unemployment and relative wages finally the short run effects of aggregate demand shocks are analyzed a popular argument for the existence of involuntary unemployment is that a worker s effort rises with wages giving employers incentives to set wages above market clearing levels it is often assumed that the worker s effort is a function of the wage level with no reference to the size of the wage in comparison with that received by other workers yet such comparisons are likely to influence an individual in his effort choice if this is the case then it seems equally likely that workers compare themselves with others both internal and external to their place of work this paper contributes to the efficiency wage literature by providing an understanding of wage setting and unemployment determination within a model where workers efforts depend on their wage relative to both the wages of other workers at the same firm and to the wages of similar workers at other firms

a non radial dea approach to measuring environmental performance data envelopment analysis dea has gained great popularity in environmental performance measurement because it can provide a synthetic standardized environmental performance index when pollutants are suitably incorporated into the traditional dea framework past studies about the application of dea to environmental performance measurement often follow the concept of radial efficiency measures in this paper we present a non radial dea approach to measuring environmental performance which consists of a non radial dea based model for multilateral environmental performance comparisons and a non radial malmquist environmental performance index for modeling the change of environmental performance over time a case study of oecd countries using the proposed non radial dea approach is also presented it is found that the environmental performance of oecd countries as a whole has been improved from 1995 to 1997

is there a trade off between supervision and wages an empirical test of efficiency wage theory abstract the logic of efficiency wage theory suggests a trade off between wages and supervision this paper reports evidence that high levels of supervision are indeed associated with lower wage levels the empirical investigation centers on the effect that safety supervision by host employers has on the wages of contract maintenance workers in the petrochemical industry this narrow focus is important special institutional features of the contract employment relationship in petrochemicals make it possible to ameliorate econometric problems that may have influenced earlier studies

evaluating the environmental efficiency of a two stage system with undesired outputs by a dea approach an interest preference perspective abstract in this study we propose a new dea model to evaluate the environmental efficiency of a two stage system with undesired outputs the two stage system consists of two parts a production subsystem and a pollution treatment subsystem different choices for allocating resources to each subsystem represent different interest preferences of decision makers with the production subsystem corresponding to short term interests and the pollution treatment subsystem corresponding to long term interests based on a proposed new dea model three theorems are established to show the relationships between the interest preference parameter and the change of efficiency scores an empirical analysis was conducted using the data of 30 provinces and municipalities eight regions of china the empirical results show the effectiveness of the proposed model and the usefulness of the theorems for the real world data optimal efficiency rankings of the eight regions are provided and the efficiency rankings truly reflect the current environmental situations of these eight regions to examine the economic impacts and facilitate sustainable development we also analyze the shadow prices for undesired outputs corresponding implications of the empirical analysis are also discussed

international stock market linkages evidence from the pre and post october 1987 period abstract this paper uses recent developments in the theory of cointegration to provide new methods of testing the linkage and dynamic interactions among stock market movements our findings are in sharp contrast with previous research which discovered strong interdependence among national stock markets prior to october 1987 for the post october 1987 period however our results show that the degree of international co movements among stock price indices has increased substantially with the nikkei index the only exception furthermore the us stock market is found to have a considerable impact on the french german and uk markets in the post crash period we also find the response of the french german and uk markets to us stock market innovations to be consistent with the view of cross border informationally efficient stock markets finally we find the japanese equity market performance to have no links with both the us stock market and the stock markets in france germany and uk during the pre and post october crash period

multilateral productivity comparisons with undesirable outputs in a recent paper in this journal caves christensen and diewert i982 hereafter ccd derive what they term multilateral superlative indexes for use in the comparison of output input and productivity across economic entities the indexes derived are distinguished both by transitivity and by a high degree of characteristicity a term introduced by dreschler i 973 to refer to the degree to which the weights used in a comparison are specific to the observations being compared though the indexes are presented with the application to multicountry comparisons of output input and productivity foremost in mind the authors note that they may be useful in a number of other contexts as well i e firms and industries time series and pooled time series and cross section all of the applications mentioned or implied however have this in common they involve the comparison of productive entities all of whose outputs are sold for positive prices this is not surprising of course since most products with which economists are concerned possess this characteristic however it does render incomplete or potentially misleading the comparison of productive entities which produce significant amounts of undesirable outputs such as water and air pollution since the list of such entities is rather long and includes industries critical to many national and regional economies e g chemicals paper petroleum refining copper and steel the omission of this factor from consideration may be a matter of some importance 2 consider for example a comparison of the productivity of the steel industries

interaction between output efficiency and environmental efficiency evidence from the textile industry in jiangsu province china environmental efficiency improvement has played a crucial role in the theory and practice of stimulating clean production this paper analyzes the interaction between environmental efficiency and output efficiency particularly whether they reinforce each other or compete with each other on the basis of a data set of 137 firms in the textile industry in china s jiangsu province in the first stage generalized data envelopment analysis is applied to calculate efficiency measures of energy waste water waste gas soot and output efficiency taking capital labor water and energy as inputs industrial output value as desirable output and waste water discharges waste gas and soot emissions as undesirable outputs in the second stage analysis a structural equation model with latent variables is applied to analyze the interaction between the latent variable environmental efficiency measured by the four observed environmental indicators and output efficiency taking also into account the endogenous variable profit the main outcomes of the structural equation model are the following firstly environmental efficiency negatively impacts on profit while profit positively impacts on environmental efficiency in a similar vein output efficiency is found to depress profit while profit increases output efficiency thirdly environmental efficiency has a positive impact on output efficiency while there is no effect of output efficiency on environmental efficiency fourthly taxes impair a firm s output efficiency from the findings it follows that a swap of general taxes for an energy tax is likely to improve both output efficiency and energy efficiency the latter outcome implies a win win situation which will facilitate the further implementation and adoption of environmental policy finally the paper illustrates the applicability of structural equation modeling in efficiency analysis

upper secondary school completion and the business cycle previous evidence suggests that enrollment in post compulsory education increases decreases in cyclical downturns upturns however little evidence exists on whether enrollment is successfully transformed into completed education this paper adds to the literature by analyzing the relationship between completion of upper secondary education and regional unemployment using norwegian regional panel data on students graduating from compulsory school between 1981 and 2004 we find robust evidence that completion rates are countercyclical our results suggest that poor labor market conditions when starting upper secondary education have a lasting effect and motivate students to stay in school and graduate

unemployment long term employment relations and productivity growth using an effort regulation type of efficiency wage model it is demonstrated that a firm may respond to slackening labor markets by acting to increase the intensity with which workers work the magnitude of this work intensity effect depends on the structure of employment relations where long term employment relations are prevalent the effect of labor market slack on work intensity may be diminished these propositions are tested empirically by estimating the effects unemployment and long term employment have on productivity growth in two digit manufacturing industries copyright 1987 by mit press

cross border mergers and acquisitions by oil and gas multinational enterprises geography based view of energy strategy abstract given that global crude oil prices are significantly dropped and business consolidation transactions are markedly increased in recent years this paper to date is the first to examine the cross border merger and acquisition strategy of oil and gas multinational enterprises using a fine tuned sample of 150 large scale oil acquisition transactions us 535 billion announced by oil and gas enterprises from over 50 countries during the period 2005 2015 we endeavor to answer four fundamental research questions who is where what for who is there why who is where and there and who is a serial acquirer to do so we propose an integrated framework of geography based view of energy strategy by leveraging theoretical insights from the energy economic geography international business strategy and corporate finance literature on top of that we discuss the dynamics of the oil and gas industry and show the remarkable trends in the crude oil prices over the past three decades 1990 2016 our geographic analyses highlight that state owned oil companies from asia and a less extent europe have rapidly expanded into resource rich countries such as canada and the us to secure oil reserves as well as acquire industry specific strategic assets this research contributes to the geography based view of energy strategy and discusses policy and managerial implications to sustain the world oil and gas industry

business ascendancy and economic impasse a structural retrospective on conservative economics 1979 87 conservatives have been waging economic revolution since the late carter years have they succeeded some argue in the affirmative pointing to lower rates of inflation and the long expansion since early 1983 insisting that the fundamentals are sound others argue in the negative emphasizing the huge twin trade and federal budget deficits and the financial fragility underscored by the october 1987 stock market crash warning that the party s over both sides of this argument concentrate primarily on short term phenomena in the 1980s neither pays much attention to the experience of the conservative regime since 1979 in long term historical perspective ronald reagan and the early architects of conservative economic policy made no such mistake they sought their place in the history books as institutional innovators not economic tinkerers in this light scrutiny of the usual cyclical macroeconomic indicators may miss far reaching changes in economic structure which promise a sustained economic expansion in years to come the budget and trade imbalances of the late 1980s for example may reflect nothing more than the growing pains of a new economic order whose long run prospects are as bright as the reagan administration promised had the economic record of the new deal been evaluated in the eighth year of roosevelt s presidency one may doubt that we would have found in the standard economic aggregates signs of the profound institutional changes which were to provide the foundations for the long postwar boom

energy intensity and its determinants in china s regional economies abstract this paper contributes to the existing literature as well as policy debates by examining energy intensity and its determinants in china s regional economies the analysis is based on a comprehensive database of china s regional energy balance constructed for this project through its focus on regional china this study extends the existing literature which mainly covers nationwide studies it is found in this paper that energy intensity declined substantially in china the main contributing factor is the improvement in energy efficiency changes in the economic structure have so far affected energy intensity modestly thus there is considerable scope to reduce energy intensity through the structural transformation of the chinese economy in the future

the oil price crash in 2014 15 was there a negative financial bubble abstract this paper suggests that there was a negative bubble in oil prices in 2014 15 which decreased them beyond the level justified by economic fundamentals this proposition is corroborated by two sets of bubble detection strategies the first set consists of tests for financial bubbles while the second set consists of the log periodic power law lppl model for negative financial bubbles despite the methodological differences between these detection methods they provided the same outcome the oil price experienced a statistically significant negative financial bubble in the last months of 2014 and at the beginning of 2015 these results also hold after several robustness checks which consider the effect of conditional heteroskedasticity model set ups with additional restrictions longer data samples tests with lower frequency data and with an alternative proxy variable to measure the fundamental value of oil

location and the multinational enterprise a neglected factor this article first traces the changing world economic scenario for international business over the past two decades and then goes on to examine its implications for the location of foreign direct investment and multinational enterprise activity it suggests that many of the explanations of the 1970s and early 1980s need to be modified as firm specific assets have become mobile across natural boundaries a final section of the article examines the dynamic interface between the value added activities of multinational enterprises in different locations

modeling undesirable factors in efficiency evaluation abstract data envelopment analysis dea measures the relative efficiency of decision making units dmus with multiple performance factors which are grouped into outputs and inputs once the efficient frontier is determined inefficient dmus can improve their performance to reach the efficient frontier by either increasing their current output levels or decreasing their current input levels however both desirable good and undesirable bad factors may be present for example if inefficiency exists in production processes where final products are manufactured with a production of wastes and pollutants the outputs of wastes and pollutants are undesirable and should be reduced to improve the performance using the classification invariance property we show that the standard dea model can be used to improve the performance via increasing the desirable outputs and decreasing the undesirable outputs the method can also be applied to situations when some inputs need to be increased to improve the performance the linearity and convexity of dea are preserved through our proposal

undesirable outputs in efficiency valuations abstract efficiency measurement is usually based on the assumption that inputs have to be minimized and outputs have to be maximized in a growing number of applications however undesirable outputs are incorporated into the production model which have to be minimized in this paper various approaches for treating such outputs in the framework of data envelopment analysis dea are discussed and the resulting efficient frontiers are compared new radial measures are introduced which assume that any change of the output level will involve both undesirable and desirable outputs

renewable energy and macroeconomic efficiency of oecd and non oecd economies abstract this article analyzes the effects of renewable energy on the technical efficiency of 45 economies during the 2001 2002 period through data envelopment analysis dea in our dea model labor capital stock and energy consumption are the three inputs and real gdp is the single output increasing the use of renewable energy improves an economy s technical efficiency conversely increasing the input of traditional energy decreases technical efficiency compared to non oecd economies oecd economies have higher technical efficiency and a higher share of geothermal solar tide and wind fuels in renewable energy however non oecd economies have a higher share of renewable energy in their total energy supply than oecd economies

china s ongoing energy efficiency drive origins progress and prospects abstract in 2004 china s government launched a vigorous programme to reverse the trend of rising national energy intensity and to reduce intensity by 20 over the period 2006 2010 the aim of this paper is to examine this programme in the context of nearly 30 years of measures to enhance energy efficiency in china and thus to evaluate the likelihood that today s policies will yield improvements over a longer period the country achieved a sustained decline of energy intensity in the period 1980 2001 but this trend was reversed in 2002 this reversal arose from a shift in the structure of the economy to more energy intensive industries and from a decline in the rate of technical innovation the measures taken since 2003 have been directed principally at energy intensive industries but have also addressed other sectors of the economy though the energy intensity target for the year 2010 may be achieved greater efforts will be needed to address a number of constraints which include the reluctance to use economic and financial instruments the dependency of energy policy on industrial and social policies the nature of political decision making and of public administration a shortage of skills and social attitudes to energy

to reduce energy consumption and to maintain rapid economic growth analysis of the condition in china based on expended ipat model abstract as one of the important driving forces of world economic development china s rapid economic growth has not only supplied the world with a large number of manufactured goods but also caused china s sustained and rapid increase in energy consumption because of the characteristics of china s economic development and overall low productivity derive from them in many years according to the ipat model and its expansion this article figures out china s indicators of economic growth and changes in energy consumption brought by technological progress since 1986 empirical results show that despite many years efforts china s high speed economic growth is still largely dependent on massive energy consumption how to maintain rapid economic growth while reducing energy consumption china has faced the very problem it needs to address

using data envelopment analysis for estimating energy saving and undesirable output abatement a case study in the organization for economic co operation and development oecd countries abstract environmental protection is one of the main concerns of the international community countries show meticulous attention to environmental issues by considering eco efficiency the eco efficiency evaluation of countries is a complex and multidisciplinary topic data envelopment analysis has widely been applied to measure the eco efficiency of organization for economic co operation and development countries in previous studies energy inputs have not been contemplated the subject becomes more important when there are non discretionary factors in this paper the eco efficiency of countries in the organization for economic co operation and development is assessed given energy inputs undesirable outputs and non discretionary factors to this end slack based and range adjusted measures are extended also new environmental indices are introduced the relationship between consumption of energy inputs and production of undesirable outputs can be addressed by two new environmental indices spearman correlation test indicates a direct and positive relationship between potential of energy saving and potential of undesirable output abatement france germany luxemburg norway sweden and the united kingdom are recognized as eco efficient countries south korea and italy have the highest and lowest potential for energy saving respectively poland and iceland are countries with the highest and lowest potential for undesirable output abatement respectively it can be concluded that countries producing high undesirable outputs may not operate eco efficiently and thus have an extreme potential to save the optimum energy moreover countries consuming low energy may operate eco efficiently and have a low potential to reduce undesirable outputs

a re examination of the structure of unemployment this paper examines whether there has been a structural change in the sensitivity of unemployment to the business cycle in the united states the analytical framework of the investigation rests on two functional relationship between unemployment and economic activity introduced by thurow 1965 the results are conclusive in suggesting that there has been no change in this sensitivity over the period 1948 88 qi thus both total unemployment and various categories including sex race age and industry of unemployment are as sensitive to variations in the level of economic activity today as they were three decades ago

what induced china s energy intensity to fluctuate 1997 2006 abstract china is the second largest energy consumer in the world during 1997 2002 china s energy intensity declined by 33 however it rose by 10 7 over 2003 2005 and declined by 1 2 in 2006 what induced china s energy intensity to fluctuate so drastically industry accounts for approximately 70 of the total energy consumption in china in this paper we decompose china s industrial energy intensity changes between 1997 and 2002 into sectoral structural effects and efficiency effects measured by sectoral energy intensities at two digit level and including the shifts of product mix in the sub sector or firm level using tornqvist and sato vartia index methods the results show that in this period efficiency effects possibly contributed to a majority of the decline while the contribution from structural effects was less during 2003 2005 the excessive expansion of high energy consuming sub sectors and the high investment ratio were foremost sources of the increasing energy intensity attributed to the government efforts the energy intensity has started to decline slightly since july 2006 in future to save more energy in addition to technical progress china should attach more importance to optimizing its sectoral structure and lowering its investment ratio

the productivity and efficiency of the australian electricity supply industry australia s electricity supply industry has been through a period of reform over the last 10 years the purpose of this paper is to analyse the changes that have occurred to the australian electricity supply industry over the past 30 years in order to evaluate to what degree these reforms have improved the productivity and efficiency performance of the industry

total factor energy efficiency of regions in china abstract this paper analyzes energy efficiencies of 29 administrative regions in china for the period 1995 2002 with a newly introduced index most existing studies of regional productivity and efficiency neglect energy inputs we use the data envelopment analysis dea to find the target energy input of each region in china at each particular year the index of total factor energy efficiency tfee then divides the target energy input by the actual energy input in our dea model labor capital stock energy consumption and total sown area of farm crops used as a proxy of biomass energy are the four inputs and real gdp is the single output the conventional energy productivity ratio regarded as a partial factor energy efficiency index is computed for comparison in contrast to tfee our index is found fitting better to the real case according to the tfee index rankings the central area of china has the worst energy efficiency and its total adjustmentof energy consumption amount is over half of china s total regional tfee in china generally improved during the research period except for the western area a u shape relation between the area s tfee and per capita income in the areas of china is found confirming the scenario that energy efficiency eventually improves with economic growth

do efficiency wages explain dismissals this study modifies rebitzer s 1987 model of efficiency wages to predict dismissal from employment using a sample selection method and data from australian workplaces the analysis supports the predictions that both very high and very low levels of required effort loose labour markets and high dismissals costs are associated with fewer dismissals among other results we find extensive internal labour markets and active unions reduce dismissals the evidence suggests that large employers rely more heavily on dismissals to motivate employees although such employers screen more effectively and so exhibit lower dismissal rates jel j24 j41 j42

the incentive effects of dismissals efficiency wages piece rates and profit sharing the relation of several incentive schemes to productivity is studied with a particular emphasis on the effects and determinants of dismissals dismissals turn out to be positively but in a nonlinear way associated with productivity similarly profit sharing raises productivity wages and piece rates are insignificant profit sharing decreases the number of dismissals made by firms copyright 1991 by mit press

are wages too low empirical implications of efficiency wage models firms may pay efficiency wages to enhance productivity the conventional presumption is that efficiency wages are inefficiently high because they lead to unemployment that is also inefficiently high government policies that lower wages raise output using a simple and general efficiency wage model this paper finds a necessary and sufficient condition for the opposite conclusion if the condition holds wages are inefficiently low leading to productivity that is also inefficiently low it is the high wage policies that raise output even if they also lower employment published empirical results support the condition no evidence is found for the conventional presumption

the economics of organization the transaction cost approach the transaction cost approach to the study of economic organization regards the transaction as the basic unit of analysis and holds that an understanding of transaction cost economizing is central to the study of organizations applications of this approach require that transactions be dimensionalized and that alternative governance structures be described economizing is accomplished by assigning transactions to governance structures in a discriminating way the approach applies both to the determination of efficient boundaries as between firms and markets and to the organization of internal transactions including the design of employment relations the approach is compared and contrasted with selected parts of the organization theory literature

low carbon economy efficiency analysis of china s provinces based on a range adjusted measure and data envelopment analysis model abstract to guide the policy adjustment in the new normal economic mode this study uses a range adjusted measure and data envelopment analysis model to evaluate the provincial comprehensive efficiencies and explore the factors causing poor performance in china during 2001 2014 empirical analysis draws the following conclusions 1 the comprehensive efficiencies of most provinces present upward trends which imply the positively contribution of previous efficiency related policies 2 contrary to economic levels the comprehensive efficiency of the central region is lower than that in the east but higher than that in the west this result confirms the existence of extensive growth and implies that developed regions should be largely responsible for the low comprehensive efficiency of the country 3 except for a few outliers the comprehensive efficiency level of a province is highly correlated to its climatic characteristics this phenomenon offers new ideas for the central government to create differential efficiency related policies 4 for east provinces labor input energy input gross domestic product gdp output and co2 emissions are all important in improving the comprehensive efficiency efficiency related policies should focus on technical progress for west and central provinces labor input and gdp output are the main contributors to inefficiency the key policy direction of these provinces should be the improvement of human resource efficiency

the competition situation analysis of shale gas industry in china applying porter s five forces and scenario model abstract with the increasing of energy demand and environmental pressure china government has been exploring a way to diversify energy supply shale gas development is becoming an important energy strategy in china in recent years due to giant shale gas reserves however the shale gas market is preliminarily shaping in china so that many factors have great influence on its competition to find these factors and to control them rationally is good for the cultivating chinese shale gas market five forces model for industry analysis puts an insight into the competitive landscape of shale gas market by showing the forces of supplier power buyer power threat of substitution barriers to entry and degree of rivalry illustrating the key factors that affect competitive landscape provides a view into the situation of shale gas industry the variation tendency of shale gas industry is analyzed by setting various scenarios finally some suggestions are proposed in order to keep the development of shale gas industry positively

the determinants of dismissals tests of the shirking model with individual data abstract this study tests the shirking model by estimating dismissal equations with data on individual workers fires were found to depend negatively on firm size and on the local and industry unemployment rates and to depend positively on the capital labor ratio

sovereign wealth fund investments in europe as an instrument of chinese energy policy abstract chinese sovereign wealth funds swfs are new instruments of chinese go global strategy and the politics of maintaining raw materials and energy security europe has lured 60 of the total usd 27 3 billion invested by chinese swfs in the energy sector globally which provokes the question as to how important swf investments are in the political sense and what security concerns they bring this paper is the first that presents a comprehensive picture of chinese swf investments in the european energy market and one of the very few papers about swfs based on multiannual comprehensive empirical data the author argues that chinese swfs are different players on the energy market than private investors could be potentially harmful for some european interests by installing representatives on the company boards china gains access to sensitive information that could be then transferred to chinese competitors moreover through its swfs china could take control over energy companies or critical infrastructure and increase its political influence in european countries making them more vulnerable to political pressure therefore the european policy makers should consider taking special steps to monitor and maybe limit chinese swfs expansion in the energy sector

china s sovereign wealth fund investments in overseas energy the energy security perspective abstract sovereign wealth funds swfs are state owned investment funds that invest in real and financial assets since the global financial crisis in 2008 swfs investments have resulted in national security concerns of host countries because swfs continue to expand rapidly and have become increasingly active in real time strategic transactions given this background china which has the biggest swf in the world is facing severe challenges of energy resources shortages while its plan is to accomplish social and economic development goals energy security is a key driving force of the energy investment policy of china s swfs this makes the swf investments more complicated and more politically sensitive the combination of sovereign rights and the strategic importance of energy also makes geopolitics more complicated and brings more uncertainty to swf investments this article explores the relationship between energy security and energy investments of china s swfs it is recognised that the energy investment of swfs must follow a sustainable path to coordinate energy security economic growth return on investment and national security concerns government policymakers are urged to balance the financial and political returns on swfs against potential negative effects the conclusion presents insights for policymakers energy scholars and swf researchers

making do with less working harder during recessions why did productivity rise during recent recessions one possibility is that average worker quality increased a second is that each incumbent worker produced more the second effect is termed making do with less using data from 2006 to 2010 on individual worker productivity from a large firm these effects can be measured and separated for this firm most of the gain in productivity during the recession was a result of increased effort additionally the increase in effort is correlated with the increase in the local unemployment rate presumably reflecting the costs of losing a job

the evolution of wind energy policies in china 1995 2014 an analysis based on policy instruments abstract the rapid growth of china s installed wind power capacity in recent years is closely related to the wind energy policies issued by the chinese government using content analysis and quantitative analysis methods this paper studies the historical evolution of chinese wind energy policies based on 72 wind energy policies issued in the past two decades 1995 2014 this paper analyzes the issuing organization form number and stringency of wind energy policies and compares different policy instruments in two periods the results show that the number and stringency of wind energy policies fluctuated greatly from 1995 to 2014 and that more than twenty organizations had independently or jointly issued the policies the main organization issuing wind energy policies however is the department that controls key economic and administrative resources and not the one that is in charge of wind energy of the 72 policies issued twenty three took the form of notices and eleven were measures as to the policy instrument environmental policies are most widely applied by the chinese government and regulation control and goal planning instruments are the ones most frequently adopted furthermore the application of supply and demand type policies is inadequate and few effective instruments have been adopted

efficiency wage models of unemployment keynesian economists hold it to be self evident that business cycles are characterized by involuntary unemployment but construction of a model of the cycle with involuntary unemployment faces the obvious difficulty of explaining why the labor market does not clear involuntarily unemployed people by definition want to work at less than the going wage rate why don t firms cut wages thereby increasing profits

the power industry reform in china 2015 policies evaluations and solutions abstract more than a decade ago in china s electric power industry the investment for generation side and power grids was inadequate and the gap between power supply and demand kept enlarging in order to relief the problems above power industry reform has been carried out in 2002 under the guidance of no 5 document by the central government the reform in 2002 has made a series of achievements including the enhancement of operation efficiency of power industry and the fulfillment of power demand all over the country during the past decade as the rapid development of the society and economy the external environment of china s power industry has changed greatly however the pricing and planning mechanism of china s power industry still operates following the requirements of no 5 document this has led to a number of problems including twisted pricing mechanism irrational power system planning inefficient utilization of renewable energy and so on these problems have not only hindered the development of power industry in china for quite a long time but also brought negative influence on the business operation of upstream and downstream industries therefore chinese government has issued no 9 document in 2015 and launched a new round of power industry reform policies were carried out to form new pricing mechanism new policies about renewable energy generation and power system planning process to solve the problems mentioned above this paper has reviewed the history of reform in 2002 and summarized the existing problems of china s power industry besides the main policies of no 9 document were deeply analyzed and their significance as well as backwards were illustrated at last solutions were proposed accordingly and these solutions have considerable theoretical and practical significance to china s electric power industry reform in the future

the revenge of homo economicus contested exchange and the revival of political economy recent developments in microeconomic theory have shown that the self interested behavior underlying neoclassical theory is artificially truncated it depicts a charmingly victorian but utopian world in which conflicts abound but a handshake is a handshake but a handshake is not always a handshake studies of principal agent analysis the economics of information radical political economy mechanism design and transactions cost economics have all focused on the difficulties involved in policing and enforcing the actual process of market exchange abandoning the victorian world of neoclassical theory will redirect economists to an older conception of their profession what once was called political economy by taking optimizing more seriously post walrasian economics has inspired a revolution in economic thought fostering both new theoretical departures and alternative conceptions of the capitalist economy we will offer our own interpretation of this literature focusing on the widely recognized fact that the terms arising from exchange are not generally enforceable at zero cost to the exchanging parties where some aspect of the good or service supplied is both valuable to the buyer and costly to provide the absence of third party enforcement of claims gives rise to endogenous enforcement strategies we refer to this relationship as a contested exchange because unlike the transactions of walrasian economics the benefit the parties derive from the transaction depends on their own capacities to enforce competing claims

2014 oil plunge causes and impacts on renewable energy abstract following four years of relative stability at around 106 per barrel bbl oil prices have declined sharply since june 2014 and are expected to remain low for a considerable period of time there are multiple factors which are being considered behind the plunge in the price of oil since june 2014 most observers have conjectured that domestic oil boom in the united states and iraq is the major cause for the falling oil prices some have suggested that a major shock to oil price expectations occurred after the november 2014 meeting of opec when they did not cut production despite the steady increase in non opec oil production in this paper first we analyzed the effect of various factors on the oil prices and then we studied impacts of the falling oil prices on non hydro renewable energy we compare the recent decline in oil prices with previous episodes up to 1996 we show that the demand and supply formula cannot be implemented to the current oil plunge the study shows that so far the recent plunge in oil prices has produced no major impact on renewable energy sector we found that renewable energies such as solar and wind are increasingly becoming cost competitive with fossil fuel energy however the oil price crash could hurt the short term outlook for certain specific clean energy technologies such as bio fuel and electric vehicles that do compete with oil based transportation while long term low oil prices may threaten renewable energies climate policies have the potential to act as a counterweight encouraging long term low carbon investment

the worker discipline effect a disaggregative analysis the authors test for the presence of a worker discipline effect wherein macroeconomic conditions influence worker effort and examine interindustry variation in its strength an employment function analysis is first used to find evidence of a worker discipline effect in the majority of u s three digit manufacturing industries a factor analysis of industry firm and labor market characteristics is then used to identify several underlying factors by which industries can be distinguished the authors find that the strength of the worker discipline effect is positively and significantly correlated with the degree to which industries have secondary characteristics copyright 1990 by mit press
