optimal incentive schemes with many agents the grossman hart principal agent model of moral hazard is extended to the multiple agent case to explore the use of relative performance in optimal incentive contracting under the assumption that the principal chooses incentive schemes to implement agent actions as nash equilibria necessary and sufficient conditions are derived for the optimality of independent contracts of rank order tournaments and for attainability of the first best in this context the relation of the principal s welfare to the correlation between the underlying randomness in outputs of different agents is also investigated finally some problems with the nash equilibrium implementation assumption are discussed in this paper we extend the grossman hart analysis of the principal agent problem to a multiple agent setting in this version of the problem a risk neutral principal is assumed to observe the output or a performance index for each risk averse agent the output of any agent depends on a privately observable action chosen by the agent and an exogenous random variable the realization of which is not observed either by the principal or by the agent before choosing its action we especially focus attention on the role of relative performance evaluation in optimal incentive contracts and the way this depends on properties of the underlying production technology and the joint distribution of the random variables affecting the outputs of different agents in section 2 of the paper we consider the principal s problem of finding an optimal incentive scheme and an action tuple for agents subject to the constraint that the latter be implemented as a nash equilibrium between agents by the chosen incentive scheme where agents must attain at least their reservation utilities a characterization of optimal incentive schemes is derived analogous to the grossman hart characterization for the single agent problem this characterization is then utilized to find sufficient and generically necessary conditions for a optimal contracts for any agent to be independent of the performance of other agents and b optimality of rank order tournaments where payments depend solely on ordinal comparisons of output across agents we then describe a necessary and sufficient condition for the principal to extract maximum advantage from relative performance clauses i e achieve the first best level of expected utility in the multiagent situation an implication of this result is that under fairly weak conditions perfect correlation in the underlying production uncertainties for different agents enables the principal to attain the first best if and only if sufficiently heavy penalties can be inflicted on agents we then enquire what happens in intermediate cases of non perfect correlation it turns out that while in general the principal s welfare is a continuous function of the correlation coefficient it is not always nondecreasing in the latter because the correlation coefficient is not a general measure of association between two random variables but rather a measure of linear association between them

energy growth long term relationship under structural breaks evidence from canada 17 latin american economies and the usa abstract we study the relationship and the causal link between electric power consumption epc and gross domestic product gdp both per capita for 17 countries in latin america canada and the usa considering that many of these economies underwent important economic crises in the last three decades we therefore model the epc gdp relationship through a vec specification that allows for structural breaks along with a robust testing methodology of causal links based on the concepts of weak and super exogeneity rather than granger causality evidence favorable to the growth hypothesis epc gdp is found for eight countries while data of three countries support the conservation hypothesis gdp epc for three countries evidence is favorable to the neutrality hypothesis but should be considered with caution as for the remaining five countries the evidence is not conclusive

energy consumption and economic growth nexus in tanzania an ardl bounds testing approach abstract in this paper we examine the intertemporal causal relationship between energy consumption and economic growth in tanzania during the period of 1971 2006 unlike the majority of the previous studies we employ the newly developed autoregressive distributed lag ardl bounds testing approach by pesaran et al 2001 bounds testing approaches to the analysis of level relationships journal of applied econometrics 16 289 326 to examine this linkage we also use two proxies of energy consumption namely total energy consumption per capita and electricity consumption per capita the results of the bounds test show that there is a stable long run relationship between each of the proxies of energy consumption and economic growth the results of the causality test on the other hand show that there is a unidirectional causal flow from total energy consumption to economic growth and a prima facie causal flow from electricity consumption to economic growth overall the study finds that energy consumption spurs economic growth in tanzania

on electricity consumption and economic growth in china abstract the invention and application of the electric power technology triggered the second industrial revolution in human history which marked the human society entered the age of electricity electricity provides the sustainable power for economic and social development with the rapid development of economy the electricity consumption is also increasing the increase of electricity consumption has further promoted the progress of the industrial economy in order to achieve the goal of improving the level of economic development while reducing energy consumption it is necessary to reveal the relationship between electricity consumption and economic growth this study is an extensive overview of the literature surrounding this topic in this paper we focus on the relationship between electricity consumption and economic growth in china we first analyze the general situation of china s electricity consumption and economic development then we explore the relationship between china s electricity consumption and economic growth from three dimensions i e the time dimension the regional dimension and the industrial dimension finally we study the key issues in the research of the relationship between electricity consumption and economic growth including variable selection model construction and results discussion this work suggests that the nature of the nexus in china should and can be explored from a wider perspective by developing a suitable integrated methodological framework

moral hazard in risk averse teams holmstrom 1982 has shown that a non budget balancing contract induces a team of risk neutral agents to choose the first best effort levels this is not generally true when agents are risk averse furthermore a massacre contract which punishes all but one agent when the outcome is low can attain the first best over a wider range of parameters than any other budget balancing contract

capital budgeting and delegation abstract as part of our ongoing research into capital budgeting processes as responses to decentralized information and incentive problems we focus in this paper on when a level of a managerial hierarchy will delegate the allocation of capital across projects and time to the level below it in our model delegation is a way to save on costly investigation of proposed projects therefore it is more extensive the larger are the costs of such investigations this delegation takes advantage of the fact that the lower level manager s preferences are assumed to be similar though not identical to those of the higher level

internal capital markets and the competition for corporate resources this article examines the role of corporate headquarters in allocating scarce resources to competing projects in an internal capital market unlike a bank headquarters has control rights that enable it to engage in winner picking the practice of actively shifting funds from one project to another by doing a good job in the winner picking dimension headquarters can create value even when it cannot help at all to relax overall firm wide credit constraints the model implies that internal capital markets may sometimes function more efficiently when headquarters oversees a small and focused set of projects this article analyzes the process by which internal capital markets channel limited resources to different uses inside a company in so doing it seeks to address two related sets of questions first what is the fundamental economic rationale for creating an internal capital market that is under what circumstances can it make sense to combine several technologically distinct projects under one roof and have them seek funding from corporate headquarters as opposed to setting them up as stand alone companies that each raise external financing on their own second given this rationale what is the optimal size and scope of an internal capital market should headquarters be involved in funding a large number of projects or just a few and should these projects be unrelated to one another or in similar lines of business the answers to both sets of questions flow from the insight that in a credit constrained setting where not all positive npv projects can be financed headquarters can create value by actively reallocating scarce funds across projects for example the cash flow generated by one division s activities may be taken and spent on investment in another division where the returns are higher or alternatively one division s assets may be used as collateral to raise financing that is then diverted to the other division simply put individual projects must compete for the scarce funds and headquarters job is to pick the winners and losers in this competition

a dynamic panel study of economic development and the electricity consumption growth nexus abstract this study examines the relationship between electricity consumption and economic growth for 88 countries categorized into four panels based on the world bank income classification high upper middle lower middle and low income within a multivariate panel framework over the period 1990 2006 the larsson et al 2001 panel cointegration test indicates there is a long run equilibrium relationship between real gdp coal consumption real gross fixed capital formation and the labor force for the high upper middle and lower middle income country panels the results from the panel vector error correction models reveal 1 bidirectional causality between electricity consumption and economic growth in both the short and long run for the high income and upper middle income country panels 2 unidirectional causality from electricity consumption to economic growth in the short run but bidirectional causality in the long run for the lower middle income country panel and 3 unidirectional causality from electricity consumption to economic growth for the low income country panel

the relationship between gdp and electricity consumption in 10 asian countries the purpose of this study is to estimate the relationships between gdp and electricity consumption in 10 newly industrializing and developing asian countries using both single data sets and panel data procedures the empirical results from single data set indicate that the causality directions in the 10 asian countries are mixed while there is a uni directional short run causality running from economic growth to electricity consumption and a bi directional long run causality between electricity consumption and economic growth if the panel data procedure is implemented these empirical findings imply that electricity conservation policies through both rationalizing the electricity supply efficiency improvement to avoid the wastage of electricity and managing demand side to reduce the electricity consumption without affecting the end user benefits could be initiated without adverse effect on economic growth the findings on the long run relationship indicate that a sufficiently large supply of electricity can ensure that a higher level of economic growth

electricity consumption real gdp causality nexus evidence from a bootstrapped causality test for 30 oecd countries the goal of this paper is to examine any causal effects between electricity consumption and real gdp for 30 oecd countries we use a bootstrapped causality testing approach and unravel evidence in favour of electricity consumption causing real gdp in australia iceland italy the slovak republic the czech republic korea portugal and the uk the implication is that electricity conservation policies will negatively impact real gdp in these countries however for the rest of the 22 countries our findings suggest that electricity conversation policies will not affect real gdp

effects of renewable energy sector development on electricity consumption growth nexus in the european union abstract the aim of this study is to assess the effect of renewable energy sector development on the relationships between electricity consumption and economic growth in the european union countries in the period between 1995 and 2015 a panel vector autoregressive model is used for testing granger causality and estimating impulse response functions the results indicate that the relationships between economic growth and electricity consumption depend on the level of renewable energy sector development the greater the share of the renewable energy sector in the economy is the more noticeable the mutual dependence between the economic growth and renewable electricity consumption is in countries with relatively well developed renewable energy sectors renewable electricity consumption boosts the economy and vice versa in the remaining countries economic growth and electricity consumption are independent empirical findings suggest that policymakers should develop strategies to implement clean energy policy aimed at stimulating the development of the renewable energy sector to support economic growth

internal competition for corporate resources and incentives in teams invoking thefree rider problem in teams many observersfind profit sharing in large organizations puzzling because it should have negligible incentive effects we show that a firm can be decomposed into two separate teams whose outputs can be observed thenprofit sharing combined with competition between these two teamsfor internal resourcesfrequently solves thefree rider problem using this result we endogenize thefirm s organizational structure and show that in the presence of economies of scale small firms tend to organize as unita y firms while largefirms choose the multidivisional organizationalform

natural gas consumption and economic growth nexus panel data analysis for gcc countries abstract this study investigates the relationship between natural gas energy consumption and economic growth by including trade openness total labor force and gross fixed capital formation as a major determinants of gdp growth within the multivariate framework model in gulf cooperation council gcc countries a panel gdp model is constructed taking the period of 1980 2012 the result revealed that natural gas energy consumption is cointegrated with gdp growth in the investigated countries in addition based on the panel dynamic ordinary least square dols and the fully modified ordinary least square fmols this study concluded that the natural gas energy consumption affects the gcc s countries gdp growth positively in the long run furthermore the results from the granger causality test revealed bidirectional causality between natural gas energy consumption and gdp growth which confirms the feedback hypothesis from the outcome of this research a number of policy implications were provided for the gcc countries

pay performance sensitivity and production uncertainty abstract the pay performance sensitivity of linear incentive contracts can increase with increasing production uncertainty depending upon the timing and nature of this uncertainty this provides a possible explanation for the failure of empirical tests to yield convincing support for a negative relationship

does early child care affect children s development we study how early child care ecc affects children s development in a marginal treatment effect framework that allows for rich forms of observed and unobserved effect heterogeneity exploiting a reform in germany that induced school districts to expand ecc at different points in time we find strong but diverging effects on children s motor and socio emotional skills children who were most likely to attend ecc benefit in terms of their motor skill development children who were least likely to attend ecc gain in terms of their socio emotional skill development especially boys and children from disadvantaged families such as those with low education or migration backgrounds simulating expansions of ecc we find that a moderate expansion fosters motor skills for all children and language skills for boys and immigrant children a progressive expansion of ecc improves all children s socio emotional development but neither their motor skills nor their language skills

electricity consumption and economic growth exploring panel specific differences abstract in this paper we examine the long and short run dynamics between electricity consumption and economic activities using panel data of per capita electricity consumption and per capita gdp of 160 countries for the period of 1980 2010 accounting for the degree of electricity dependence and the level of urbanization furthermore in order to capture the differences in this relationship the full sample is divided into various subsamples based on countries income levels regional locations and oecd memberships this framework is argued and found to be appropriate since the causal links and inferences arising therefrom differ considerably among the subsamples which led us to conclude that the electricity growth nexus is highly sensitive to regional differences countries income levels urbanization rates and supply risks

estimating the environment kuznets curve hypothesis evidence from latin america and the caribbean countries this study explores the effect of economic growth gdp renewable energy consumption re and financial development fd on co2 emission co2 in latin america and caribbean countries to achieve this goal a panel co2 model was built over the period 1980 2010 the kao cointegration test results revealed that the variables are cointegrated the fully modified ols fmols results indicated an inverted u shape relationship between co2 and gdp thus confirming the environmental kuznets curve hypothesis furthermore fmols results also revealed that fd can improve environmental quality by its negative long run effect on co2 however re has no long run effect on co2 indicating that the re does not contribute to co2 reduction the vecm granger causality results revealed feedback causality between gdp re fd and co2 in both short and long run additionally granger causality results also revealed that re gdp and fd can be a good solution to reduce environmental damage since they have a causal effect on co2 this study shows the investigated countries should increase their banking loans on green energy energy efficiency and energy saving projects to reduce environmental damage in addition the above recommendation can increase the contribution of renewable energy in reducing environmental damage

growth and renewable energy in europe a random effect model with evidence for neutrality hypothesis this is an empirical study on the causal relationship between economic growth and renewable energy for 27 european countries in a multivariate panel framework over the period 1997 2007 using a random effect model and including final energy consumption greenhouse gas emissions and employment as additional independent variables in the model empirical results do not confirm causality between renewable energy consumption and gdp although panel causality tests unfold short run relationships between renewable energy and greenhouse gas emissions and employment the estimated cointegration factor refrains from unity indicating only a weak if any relationship between economic growth and renewable energy consumption in europe suggesting evidence of the neutrality hypothesis which can partly be explained by the uneven and insufficient exploitation of renewable energy sources across europe

quitters never win the adverse incentive effects of competing with superstars internal competition may motivate worker effort yet the benefits of competition may depend critically on workers relative abilities large skill differences may reduce efforts i use panel data from professional golf tournaments and find that the presence of a superstar is associated with lower performance on average golfers first round scores are approximately 0 2 strokes worse when tiger woods participates relative to when woods is absent the overall tournament effect is 0 8 strokes the adverse superstar effect varies with the quality of woods s play there is no evidence that reduced performance is attributable to media attention intensity or risky strategy adoption

electricity consumption and economic growth a time series experience for 17 african countries abstract while the availability of electricity by itself is not a panacea for the economic and social problems facing africa the supply of electricity is nevertheless believed to be a necessary requirement for africa s economic and social development this paper tests the long run and causal relationship between electricity consumption per capita and real gross domestic product gdp per capita for 17 african countries for the period 1971 2001 using a newly developed cointegration test proposed by pesaran et al 2001 and using a modified version of the granger causality test due to toda and yamamoto 1995 the advantage of using these two approaches is that they both avoid the pre testing bias associated with conventional unit root and cointegration tests the empirical evidence shows that there was a long run relationship between electricity consumption per capita and real gdp per capita for only 9 countries and granger causality for only 12 countries for 6 countries there was a positive uni directional causality running from real gdp per capita to electricity consumption per capita an opposite causality for 3 countries and bi directional causality for the remaining 3 countries the result should however be interpreted with care as electricity consumption accounts for less than 4 of total energy consumption in africa and only grid supplied electricity is taken into account

the electricity consumption versus economic growth of the polish economy abstract the aim of this contribution is an investigation of causal interdependences between electricity consumption and gdp in poland our research was conducted for total electricity consumption as well as for the industrial consumption of electricity in order to reflect the causality between gdp and electricity consumption properly we performed our investigations in a three dimensional framework with employment chosen as an additional variable we used reliable quarterly data from the period q1 2000 q4 2009 in order to check the stability of the causalities the investigations were performed on two samples a full sample and a pre crisis i e q1 2000 q3 2008 subsample we applied both traditional methods and some recently developed econometric tools we found feedback between total electricity consumption and gdp as well as between total electricity consumption and employment we also found unidirectional causality running from industrial electricity consumption to employment and no direct causal links between industrial electricity consumption and gdp in addition all these findings were in general not seriously affected by the financial and economic crises of 2008 a significant exception is the causal effect of industrial electricity consumption on employment which was more pronounced after the crisis of 2008

the nexus of electricity consumption economic growth and co2 emissions in the brics countries abstract this study reexamines the causal link between electricity consumption economic growth and co 2 emissions in the brics countries i e brazil russia india china and south africa for the period 1990 2010 using panel causality analysis accounting for dependency and heterogeneity across countries regarding the electricity gdp nexus the empirical results support evidence on the feedback hypothesis for russia and the conservation hypothesis for south africa however a neutrality hypothesis holds for brazil india and china indicating neither electricity consumption nor economic growth is sensitive to each other in these three countries regarding the gdp co 2 emissions nexus a feedback hypothesis for russia a one way granger causality running from gdp to co 2 emissions in south africa and reverse relationship from co 2 emissions to gdp in brazil is found there is no evidence of granger causality between gdp and co 2 emissions in india and china furthermore electricity consumption is found to granger cause co 2 emissions in india while there is no granger causality between electricity consumption and co 2 emissions in brazil russia china and south africa therefore the differing results for the brics countries imply that policies cannot be uniformly implemented as they will have different effects in each of the brics countries under study

are energy conservation policies effective without harming economic growth in the gulf cooperation council countries abstract this study explores the fossil fuels electricity consumption growth of the gross domestic product gdp relationship in the six gulf cooperation council gcc countries for the period 1980 2012 the aim of this study is to examine whether energy conservation policies are appropriate for these countries to reduce their high levels of electricity consumption the autoregressive distributed lag ardl and the toda yamamoto dolado lutkepohl tydl methodologies were employed to investigate this relationship the ardl results revealed that fossil fuels electricity consumption has a long run positive effect on gdp growth in the gcc countries however the tydl granger causality revealed different causality relationships among the countries a bi directional causality was found between fossil fuels electricity consumption and gdp growth in bahrain and the united arab emirates uae while one way causality from fossil fuels electricity consumption to gdp growth was found in oman and qatar on the other hand no causality was concluded between the variables in kuwait and saudi arabia from the results it is clear that energy conservation is not an ideal policy for the bahrain uae oman and qatar because it will have a negative consequence on their output however this policy can be implemented in kuwait and saudi arabia since it will not harm their output

energy consumption and economic growth revisited in african countries abstract the aim of this paper is to provide new empirical evidence on the relationship between energy consumption and economic growth for 21 african countries over the period from 1970 to 2006 using recently developed panel cointegration and causality tests the countries are divided into two groups net energy importers and net energy exporters it is found that there exists a long run equilibrium relationship between energy consumption real gdp prices labor and capital for each group of countries as well as for the whole set of countries this result is robust to possible cross country dependence and still holds when allowing for multiple endogenous structural breaks which can differ among countries furthermore we find that decreasing energy consumption decreases growth and vice versa and that increasing energy consumption increases growth and vice versa and that this applies for both energy exporters and importers finally there is a marked difference in the cointegration relationship when country groups are considered

efficient and nearly efficient partnerships this paper shows in two ways that the degree to which free riding diminishes the performance of deterministic partnerships may be less than has been generally thought first a necessary and sufficient condition is provided for a partnership to sustain full efficiency it implies that many non trivial partnerships sustain efficiency such as generic ones with finite action spaces and neoclassical ones with leontief technologies second approximate efficiency is shown to be achievable in a large class of partnerships including ones with smooth and monotonic production and disutility functions approximate efficiency is achieved by mixed strategy equilibria one partner takes with small probability an inefficient action the degree to which efficiency is approximated is restricted only by the amount of liability the partners can bear nonetheless their equilibrium payments are not arbitrarily large

electricity consumption and economic growth in china cointegration and co feature analysis abstract this paper applies the cointegration theory to examine the causal relationship between electricity consumption and real gdp gross demostic product for china during 1978 2004 our estimation results indicate that real gdp and electricity consumption for china are cointegrated and there is only unidirectional granger causality running from electricity consumption to real gdp but not the vice versa then hodrick prescott hp filter is applied to decompose the trend and fluctuation component of the gdp and electricity consumption series the estimation results indicate that there is cointegration between not only the trend components but also the cyclical components of the two series which implies that the granger causality is probably related with the business cycle the estimation results are of policy implication to the development of electric sector in china

renewable and non renewable electricity consumption environmental degradation and economic development evidence from mediterranean countries abstract in this article we develop an empirical model to investigate the causal link amid renewable and non renewable electricity consumption gdp and carbon emissions by using a panel of 9 mediterranean countries over the period 1980 2014 using the pmg panel ardl and panel econometric technics heterogeneity and cross sectional dependence among the panel were considered to explore the long and short run dynamic relationships as well as the validity of a proposed model the results provide panel empirical evidence that there is short term bidirectional causality between gdp renewable electricity consumption and co2 emissions and between non renewable electricity consumption gdp and renewable electricity consumption for the long term causal relationship the result indicates that there is bidirectional causality between non renewable electricity consumption and co2 emissions however there is evidence of unidirectional causal relationships from gdp to co2 emissions and non renewable electricity consumption and from renewable electricity consumption to co2 emissions the findings imply that non renewable electricity consumption and economic growth stimulate co2 emissions in southern and northern mediterranean countries while renewable electricity reduces them this empirical evidence suggests that expansion of renewable energy sources is a viable strategy for addressing energy security and reducing carbon emissions to protect the environment for future generations

the effect of renewable and nonrenewable electricity generation on economic growth abstract this note examines the impact of electricity generation on economic growth using data for a panel of 174 countries over the period 1980 2012 the paper makes several contributions first contrary to much of the literature the paper focuses on the effect of electricity generation on economic growth because of transmission and distribution losses and theft not all the electricity that is generated is eventually consumed making it necessary to investigate the impact of electricity generation on growth second we disentangle the impact of total electricity generation on growth into renewable and nonrenewable effects with increasing pursuit of energy security technological advances the falling costs of renewables and the movement to exploit renewable energy sources for electrification there is need to study not only the impact of traditional sources of electricity but renewable sources as well third we deviate from previous studies that focus on granger causality and or cointegration by estimating the effect of electricity generation on growth using the system generalized method of moments gmm given that electricity generation and many of the other regressors in our model may be jointly determined with gdp growth the system gmm approach is appropriate to deal with these endogeneity issues fourth we provide evidence of a link between electricity loss and economic growth our results indicate a strong positive and statistically significant relationship between renewable and nonrenewable electricity generation and growth

residential and non residential electricity dynamics abstract this paper uses u s panel data to instrument and examine the dynamics of electricity within the world market while separating between both residential and non residential electricity consumptions during the time period of 1990 2014 to better assess the true differences within each causal relationship all panel data has been separated into one full panel and three subpanels of high middle and low income the empirical framework used consists of various tests that identify the existence of cross sectional dependency a pesaran panel unit root test a westerlund panel cointegration test and the dumitrescu hurlin method of the granger causality test furthermore this paper utilizes dols to estimate any long run elastic relations between real gdp and residential or non residential electricity consumption based on the results this paper determines that no long run relationship exists between non residential electricity consumption and economic growth throughout and that the relationship between residential electricity consumption and economic growth possesses unit elastic behavior in the long run other findings throughout imply causality moves from economic growth in the direction of residential electricity consumption for all panels

electricity consumption growth nexus evidence from panel data for transition countries abstract this paper investigates the long run relationship and causality issues between electricity consumption and economic growth in 15 transition countries albania belarus bulgaria czech republic estonia latvia lithuania macedonia moldova poland romania russian federation serbia slovak republic and ukraine by using the pedroni panel cointegration method for the 1990 2006 period results suggest that the pedroni panel cointegration tests do not confirm a long term equilibrium relationship between electricity consumption per capita and real gdp per capita moreover since no cointegration was found error correction mechanisms plus causality tests cannot be run for further steps in the long term to investigate the causality between electricity consumption and economic growth overall it can be said that the electricity consumption related policies have no effect or relation on the level of real output in the long run for these countries as a conclusion the literature has conflicting results and there is no consensus either on the existence or the direction of causality between electricity consumption and economic growth thus the findings of this study have important policy implications and it shows that this issue still deserves further attention in future research

job assignments signalling and efficiency this article analyzes a model in which information about a worker s ability is only directly revealed to the firm employing the worker other firms however use the worker s job assignment as a signal of ability three results recur throughout the analysis first wage rates tend to be more closely associated with jobs than with ability levels second there is frequently an inefficient assignment of workers to jobs i e even when a firm has complete information about a worker s output third the severity of this inefficiency tends to be negatively correlated with the level of firm specific human capital in the economy

estimation of electricity demand function for algeria revisit of time series analysis abstract this paper aims to empirically re examine whether economic growth has effect on electricity consumption for algerian economy we have incorporated urbanization and trade openness in electricity demand function as additional determinants of electricity consumption for the period of 1971 2012 for empirical purpose we have applied the recently developed combined cointegration test proposed by bayer and hanck 2013 and bounds testing approach to cointegration by pesaran et al 2001 for establishing the cointegration between the variables by accommodating structural breaks the results expose that income growth leads to higher electricity demand along with urbanization being another major contributing factor of rising electricity demand in contrast trade openness leads to reduce electricity demand the causal association between the variables is further examined with the application of innovation accounting approach of vector autoregressive var the empirical evidence indicates the presence of the neutral effect between income growth and electricity use urbanization causes electricity use and electricity use causes urbanization in granger sense

electricity consumption in g7 countries a panel cointegration analysis of residential demand elasticities this article applies recently developed panel unit root and panel cointegration techniques to estimate the long run and short run income and price elasticities for residential demand for electricity in g7 countries the panel results indicate that in the long run residential demand for electricity is price elastic and income inelastic the study concludes that from an environmental perspective there is potential to use pricing policies in the g7 countries to curtail residential electricity demand and thus curb carbon emissions in the long run

why do firms use incentives that have no incentive effects this paper illustrates why firms might choose to implement stock option plans or other pay instruments that reward luck i consider a model where adjusting compensation contracts is costly and where employees outside opportunities are correlated with their firms performance the model may help to explain the use and recent rise of broad based stock option plans as well as other financial instruments even when these pay plans have no effect on employees on the job behavior the model suggests that agency theory s often overlooked participation constraint may be an important determinant of some common compensation schemes particularly for employees below the highest executive ranks many compensation plans reward or punish employees for factors they cannot control an often discussed example of this phenomenon is executive compensation where stock options are not generally indexed to the overall market however many firms also offer firm wide stock options and profit sharing plans that provide even weaker incentives than executive plans after all most workers can expect to reap trivial personal gain from their contribution to firm value or profits i consider an explanation for this phenomenon in which firms contract with employees as a means of indexing wages to market rates rather than to provide incentives while much of the agency literature has concentrated on inducing optimal effort i consider the importance of the generally overlooked participation constraint i study a model in which employees outside opportunities are correlated with firm profits or stock price and in which both turnover and adjusting the pay scheme parameters are costly given these assumptions the firm may find it most profitable to pay the employee in a way that is correlated with the outside options presented by the outside labor market despite the requisite risk premium rather than pay a fixed wage that insures participation in all states the model derived below starts from the assumption that wage adjustments are costly but that workers are willing to make part of their pay contingent

energy consumption and gdp causality a three step analysis for emerging european countries abstract the established european targets should play a leading role in the complex economic process of energy consumption and the emerging countries have to consider their implications for adjusting the energy policies at national level this paper develops investigations on the causality relationship between energy consumption and gdp in the context of emerging european countries covering the period 1980 2013 this research covers the limits identified by previous researchers by detailing the energy consumption by sources and by referring to five emerging countries in europe unlike most of the previous studies it has a double approach long and short run bidirectional relationships a detailed analysis on the impact of economic growth on the energy consumption by country is conducted in order to contribute to the enrichment of the research field towards this objective a three step analysis is performed stationarity cointegration and causality tests are considered the empirical study shows mixed results there is a balance in confirming conservation growth and neutrality hypotheses in some specific cases results imply that energy consumption and economic growth are jointly determined however a comparative analysis for different significance levels draws attention on the differences in judgment of results for this type of studies discussions on the results in terms of causality are conducted in order to identify future trends for research

cointegration and causality between electricity consumption and gdp empirical evidence from malawi abstract the granger causality gc and error correction ecm techniques were applied on 1970 1999 data for malawi to examine cointegration and causality between electricity consumption kwh and respectively overall gdp agricultural gdp agdp and non agricultural gdp ngdp cointegration was established between kwh and respectively gdp and ngdp but not with agdp the gc results detect bi directional causality between kwh and gdp suggesting that kwh and gdp are jointly determined but one way causality running from ngdp to kwh the ecm results detect causality running one way from gdp also from ngdp to kwh suggesting that a permanent rise in gdp may cause a permanent growth in electricity consumption

the causal relationship between electricity consumption and economic growth in the asean countries abstract this paper investigates the causal relationship between electricity consumption and economic growth among the association of south east asian nations asean 4 members namely indonesia malaysia singapore and thailand using modern time series techniques for the period 1971 2002 the results indicate that there is a bi directional causality between electricity consumption and economic growth in malaysia and singapore this means that an increase in electricity consumption directly affects economic growth and that economic growth also stimulates further electricity consumption in the two countries however uni directional causality runs from economic growth to electricity consumption in indonesia and thailand without any feedback effect thus electricity conservation policies can be initiated without deteriorating economic side effects in the two countries

electricity consumption and economic growth bounds and causality analyses of opec members this paper investigates the relationship between electricity consumption and economic growth for opec members the bounds test yields evidence of a long run relationship between electricity consumption and economic growth for all opec members causality results suggest that economic growth is dependent on electricity consumption in five countries less dependent in three countries and independent in three countries because these countries do not necessarily share similar political and economic traits no single universal policy implication can be inferred from the results the disparities across these causality results therefore stress the importance of formulating causality explanations while taking into account the particularities of individual countries rather than blindly applying the conventional interpretations

electricity consumption and economic growth in transition countries a revisit using bootstrap panel granger causality analysis abstract the purpose of this paper is to revisit the granger causal relationship between electricity consumption and economic growth for 15 transition economies for the period 1975 2010 using a bootstrap panel causality approach that allows for both cross sectional dependency and for heterogeneity across countries applying this approach we found a unidirectional causality running from electricity consumption to economic growth only in belarus and bulgaria from economic growth to electricity consumption in the czech republic latvia lithuania and the russian federation bidirectional causality only in ukraine while no granger causality in any direction in albania macedonia moldova poland romania serbia slovak republic and slovenia these results show that there is a limited support for the electricity led growth hypothesis nevertheless these different findings provide important implications for energy strategies and policies for transition countries

decision processes agency problems and information an economic analysis of capital budgeting procedures corporations use a variety of processes to allocate capital this article studies the benefits and costs of several common budget procedures from the perspective of a model with agency and information problems processes that delegate aspects of the decision to the agent result in too many projects being approved while processes in which the principal retains the right to reject projects cause the agent to strategically distort his information about project quality we show how the choice of a decision process depends on these two costs and specifically on severity of the agency problem quality of information and project risk capital budgeting would be easy in a world without agency and information problems the decision maker would simply calculate a project s irr and compare it to the cost of capital but in the real world those providing the funds for investment must rely on self interested agents to identify projects and provide information on expected returns as a result the quality of capital allocation depends on how effective the decision process is in attenuating agency problems and bringing forth accurate information corporations employ a variety of decision procedures in practice some decisions are fully delegated to division and plant managers typically expansion of an existing plant some decisions require approval of headquarters typically construction of a new plant and other decisions require approval conditional on the nature of the proposal such as when projects requiring more than 1 million go to headquarters while smaller projects can be approved locally 1

a theory of sales quotas with limited liability and rent sharing sales quotas are a fixture of sales compensation plans and are often associated with a significant discrete bonus this article shows that under certain assumptions about salesperson utility and the distribution of sales outcomes the optimal compensation is a discrete bonus for meeting a sales quota the results are similar when the assumption of agent risk neutrality is relaxed the model has implications for many moral hazard problems where the agent has a liability limitation and job specific skill

competition cooperation and collective choice the ability of groups to implement efficiency enhancing institutions is emerging as a central theme of research in economics this study explores voting on a scheme of intergroup competition which facilitates cooperation in a social dilemma situation experimental results show that the competitive scheme fosters cooperation competition is popular but the electoral outcome depends strongly on specific voting rules of institutional choice if the majority decide competition is almost always adopted if likely losers from competition have veto power it is often not and substantial gains in efficiency are foregone

aggregation and linearity in the provision of intertemporal incentives we consider the problem of providing incentives over time for an agent with constant absolute risk aversion the optimal compensation scheme is found to be a linear function of a vector of n accounts which count the number of times that each of the n kinds of observable events occurs the number n is independent of the number of time periods so the accounts may entail substantial aggregation in a continuous time version of the problem the agent controls the drift rate of a vector of accounts that is subject to frequent small random fluctuations the solution is as if the problem were the static one in which the agent controls only the mean of a multivariate normal distribution and the principal is constrained to use a linear compensation rule if the principal can observe only coarser linear aggregates such as revenues costs or profits the optimal compensation scheme is then a linear function of those aggregates the combination of exponential utility normal distributions and linear compensation schemes makes computations and comparative statics easy to do as we illustrate we interpret our linearity results as deriving in part from the richness of the agent s strategy space which makes it possible for the agent to undermine and exploit complicated nonlinear functions of the accounting aggregates

between group competition enhances cooperation in resource appropriation games abstract cooperation in public goods games increases in the presence of between group competition in this study we validate the effect of between group competition in a different social dilemma a resource appropriation game unlike the voluntary contributions setting group performance in this game increases with the exercise of a passive choice not appropriating units in an open access resource we conducted an incentivized experiment using 276 undergraduate students in which groups of four subjects played a resource appropriation game different groups within a session were ranked in each round according to the group s aggregate payoff this ranking determined a group performance multiplier which increased the payoffs in groups ranked above the median and decreased the payoffs in groups below the median the multipliers were small enough to keep the individual benefits from appropriation larger than the individual benefits from a higher payoff multiplier derived from an improvement in group ranking by not appropriating the resource unit we found that implementing this small group performance multiplier decreased the average appropriation by 31 this efficiency enhancing device generated a 19 percentage point increase in overall earnings in a given session

inter team contests with power differential abstract we investigate the impact of asymmetry on behavior in inter team contests in asymmetric environments one team has a greater probability of winning given the same contribution level unfair contests or has a lower cost of contributing uneven contests we explore how such asymmetries impact behavior asking how being advantaged or disadvantaged influences contributions we find both advantaged and disadvantaged teams contribute much more than theory predicts but in such a way that ex post winning probabilities of the contests are consistent with theoretical predictions at the individual level contributions are predicted by beliefs about own team and opponent team contributions the determinants of contribution by members of the disadvantaged team differ depending on the nature of asymmetry contributions by the disadvantaged team members are responsive to beliefs about contribution by opponents in unfair contests while in uneven contests they are responsive to beliefs about the contribution by teammates

the relationship between energy consumption energy prices and economic growth time series evidence from asian developing countries this paper estimates the causal relationships between energy consumption and income for india indonesia the philippines and thailand using cointegration and error correction modelling techniques the results indicate that in the short run unidirectional granger causality runs from energy to income for india and indonesia while bidirectional granger causality runs from energy to income for thailand and the philippines in the case of thailand and the philippines energy income and prices are mutually causal the study results do not support the view that energy and income are neutral with respect to each other with the exception of indonesia and india where neutrality is observed in the short run c 2000 elsevier science b v all rights reserved jel classifications c22 q43 q48

efficiency in partnerships we provide the necessary and sufficient condition for a partnership to be able to sustain efficiency when the output is stochastic when limited liability is imposed we show that only the level of the average liability of the partnership is important the individual levels of liability are irrelevant however the allocation of the total liability among the partners is crucial when additional conditions such as neutrality or individual rationality are imposed

the role of portuguese electricity generation regimes and industrial production abstract this paper examines how renewables special regime simultaneously interact with conventional sources ordinary regime within the portuguese electricity generation system there is also an appraisal of the relationship between these two regimes and economic activity using the industrial production index first difference var modelling was applied for monthly data for the time span of 2007 m1 to 2012 m10 the appropriateness of the var is proved the relationship between variables develops within a structure of endogeneity i e they generate feedback and may be both explained and explaining variables simultaneously the outcomes show a strong complementarity between the ordinary and special regimes economic activity causes electricity consumption but only the special regime causes economic activity moreover the non renewable component of the special regime does not cause a need for backup from either the ordinary regime or imports contributing to a reduction in energy dependency

economic welfare impacts from renewable energy consumption the china experience over the last years renewable energy sources have increased their share on electricity generation of china due to environmental and security of supply concerns in this work author assesses the role of both the amount and share of renewable energy consumption in economic welfare using cobb douglas type production functions this assessment is carried out by multivariate ols and spss software for china from 1978 to 2008 results indicate that a 1 increase in renewable energy consumption rec increases real gdp by 0 120 gdp per capita by 0 162 per capita annual income of rural households by 0 444 and per capita annual income of urban households by 0 368 respectively the impact of renewable energy consumption share srec on economic welfare is insignificant and an increasing share of rec negatively affects economic welfare growth to a certain extent in this paper the cost structural demand accounting mechanism and policy reasons of renewable energy development are interpreted marginal effects analysis show that the shape of sound and robust renewable energy institutions and policies would matter for increasing the standards of economic welfare in the context of speeding up renewable energy development and increasing share of renewable energy consumption especially the goal oriented policy refinement should be addressed efficiently in improvement households income while increasing share of renewable energy consumption c 2011 elsevier ltd all rights reserved

the electricity consumption and gdp nexus for the fiji islands fiji is a small open island economy dependent on energy for its growth and development hence the relationship between energy consumption and economic growth is crucial for fiji s development in this paper we investigate the nexus between electricity consumption and economic growth for fiji within a multivariate framework through including the labour force variable we use the bounds testing approach to cointegration and find that electricity consumption gdp and labour force are only cointegrated when gdp is the endogenous variable we use the granger causality f test and find that in the long run causality runs from electricity consumption and labour force to gdp implying that fiji is an energy dependent country and thus energy conservation policies will have an adverse effect on fiji s economic growth

the link between renewable energy production and gross domestic product in africa a comparative study between 1980 and 2008 abstract renewable energy re projects are arguably one of the most important strategies that can be used in the mitigation of climate change impacts at the same time re technologies can generate clean energy and potentially boost the economy of the african continent it is thus not surprising that recent studies have investigated the relationship between re and economic growth in some african countries however the limitation of these reductionist analytical frameworks is that they can conceal the true regional picture in terms of the link between investments in re technologies and gross domestic product gdp this holistic analysis is important in order to inform regional policies on climate change the article uses statistical analytic techniques to examine the correlation between re production and economic growth across different blocks of the african continent between 1980 and 2008 the analysis is between geographical blocks e g southern africa western africa etc and between oil and non oil producing blocks generally speaking while there exists a similar pattern in all the studied blocks in terms of mean standard deviation and correlation between re and gdp a few exceptions can be found for instance the rise in re gdp correlation from 1992 1993 onwards was conspicuously higher in north africa and oil producing countries compared to all the other blocks similarly southern africa was the only block where the correlation between re and gdp was negative throughout the period under review except 1988 1989 and 1997 when it was positive

a literature survey on energy growth nexus abstract this paper provides a survey of the recent progress in the literature of energy consumption economic growth and electricity consumption economic growth causality nexus the survey highlights that most empirical studies focus on either testing the role of energy electricity in stimulating economic growth or examining the direction of causality between these two variables although the positive role of energy on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies a general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption electricity consumption and economic growth as a policy implication to avoid from conflicting and unreliable results the authors may use the autoregressive distributed lags bounds test two regime threshold co integration models panel data approach and multivariate models including new variables such as real gross fixed capital formation labor force carbon dioxide emissions population exchange rates interest rates etc thus the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time

ex post unbalanced tournaments tournaments create strong incentives under the assumption that the competition between the agents is balanced if at the outset one agent is stronger than the other the tournament is ex ante unbalanced and incentives break down handicaps can in this case restore incentives in practice competing agents are often overall equally strong but have different sorts of strengths then competition will typically be unbalanced ex post and incentives break down but handicaps cannot be used we show how a simple means introducing the possibility of a tie can often resolve the problem we examine under what conditions incentives are maximized by ties

demand customer base line and demand response in the electricity market a survey the increasing use of demand side management as a tool to reliably meet electricity demands at peak time has stimulated interest among researchers consumers and producer organiza tions managers regulators and policymakers this research reviews the growing literature on models which are used to study demand customer base line cbl and demand response in the electricity market after characterizing the general demand models the cbl based on which the demand response models are studied is reviewed given the experience gained from the review and existing conditions the study combines an appropriate model for each case for a possible application to the electricity market moreover it discusses the implications of the results in the literature these aspects are studied independently the main contribution of this survey is attributed to the treatment of the three issues as sequentially interdependent the review is expected to enhance the understanding of the demand cbl and demand response in the electricity market and their relationships the objective is conducted through a combination of demand and supply side managements in order to reduce demand through different demand response programs during peak times this enables electricity suppliers to save costly electricity generation and at the same time reduce energy vulnerability
