global energy use decoupling or convergence we examine the key factors driving change in energy use globally over the past four decades we test for both strong decoupling where economic growth has less effect on energy use as income increases and weak decoupling where energy use declines overtime in richer countries ceteris paribus our econometric approach is robust to the presence of unit roots unobserved time effects and spatial effects our key findings are that the growth of per capita energy use has been primarily driven by economic growth convergence in energy intensity and weak decoupling there is no sign of strong decoupling

an analysis of feed in tariff remuneration models implications for renewable energy investment recent experience from around the world suggests that feed in tariffs fits are the most effective policy to encourage the rapid and sustained deployment of renewable energy there are several different ways to structure a fit policy each with its own strengths and weaknesses this paper presents an overview of seven different ways to structure the remuneration of a fit policy divided into two broad categories those in which remuneration is dependent on the electricity price and those that remain independent from it this paper examines the advantages and disadvantages of these different fit models and concludes with an analysis of these design options with a focus on their implications both for investors and for society

support systems for the diffusion of renewable energy technologies an investor perspective concern over climate change impacts and the projected depletion of fossil fuels has urged more governments to adopt policies that stimulate the diffusion of renewable energy technologies ret with an increasingly diverse suite of support instruments the question emerges as to which instruments or combinations are able to achieve faster more substantial diffusion results although various support instruments were extensively addressed in policy studies there is still no consensus this is partly because many policy studies take a policy maker approach in comparing support instruments leaving relationships between policy design and policy results as a black box this paper proposes an investor oriented perspective to analyze the diffusion potential of support systems for ret the main argument is that it is not the type of support instrument but rather its risk profitability characteristics that influence investor behavior and the rate of diffusion the two instruments most frequently discussed and compared are the feed in tariff and the quota model the analysis in this paper concludes that policy design is crucial while often feed in tariffs are applauded and quota system feared feed in tariffs may also bring about disappointing diffusion results when poorly designed while quota systems may be also conceived as attractive instruments for independent power producers

income resources and electricity mix this paper presents evidence on a national level electricity ladder which sees countries transition toward coal and natural gas and finally nuclear power and modern renewables such as wind power for their electricity needs as they develop the extent to which countries climb the electricity ladder is dependent on energy endowments the results imply that the environmental implications of economic development differ in countries with different energy resource endowments an effective global carbon mitigation strategy will require developing countries to leapfrog the middle rungs of the electricity ladder

when higher prizes lead to lower efforts the impact of favoritism in tournaments we investigate the relationship between tournament prices and effort choices in the presence of favoritism high tournament prizes can decrease agents effort supply when the choice of the winner is not perfectly objective but affected to some extent by personal preferences of an evaluator

executive compensation strategic competition and relative performance evaluation theory and evidence we examine compensation contracts for managers in imperfectly competitive product markets we show that strategic interactions among firms can explain the lack of relative performance based incentives in which compensation decreases with rival firm performance the need to soften product market competition generates an optimal compensation contract that places a positive weight on both own and rival performance firms in more competitive industries place greater weight on rival firm performance relative to own firm performance we find empirical evidence of a positive sensitivity of compensation to rival firm performance that is increasing in the degree of competition in the industry

two sided uncertainty and up or out contracts a bilateral moral hazard problem provides a rationale for up or out employment contracts the employer sets a wage higher than opportunity cost to induce the worker to invest in firm specific capital if the individual does not make the grade it is in the firm s interest ex post to fire him had the initial arrangement not included provisions for firing individuals the firm would underreport the value of the employee wrecking the incentive scheme the basic model permits both firm and worker to be risk neutral therefore it admits a straightforward multiperiod extension which we also investigate

policy as a porter of re component export or import evidence from pv wind energy in oecd and brics abstract seeking empirical support for the porter hypothesis ph applied to the trade of photovoltaic pv and wind energy components this study examines effects of the interaction between innovative capacity and two kinds of renewable energy re policies feed in tariff fit and renewable portfolio standards rps on export in oecd and brics countries meanwhile the effect of such policies in import countries is estimated given prominent growth in re component export by emerging economies and trade disputes with developed countries the result reveals exporter innovative capacity as negatively correlated with their export when it is interacted with rps dummy suggesting inverse evidence for ph on the other hand importer annual pv share which proxies demand for components was positively associated with their import provided the presence of fit rps overall policies in importer countries exert a robust influence over their import growth while those in exporter countries may not facilitate or have a negative effect on their export the result above is in line with the theoretical implication on the effect of re policy while it contradicts to the narrowly strong version of ph this indicates that positive effect of the interaction between policy and innovative capacity on export performance might depend on the distribution of the additional surplus from fit rps

population aging and carbon emissions in oecd countries accounting for life cycle and cohort effects this paper investigates the relationship between emissions of carbon dioxide and the ongoing process of demographic transition in oecd countries our research is motivated by suggestions in the literature that emission relevant consumption patterns may depend on the position in the life cycle and on the birth cohort to which people belong we augment standard macroeconomic emission regressions by including the age and cohort composition of the population our estimation results on a panel of data for 26 countries spanning the period 1960 2005 suggest that both life cycle and cohort effects belong in a macroeconomic emission function for carbon dioxide we find that shifts in both the age and the cohort composition have contributed to rising carbon emissions in oecd countries

the effect of feed in tariffs on renewable electricity generation an instrumental variables approach while carbon taxes and other market based instruments are widely regarded as optimal for climate mitigation political constraints have prevented governments from using them instead narrower instruments including the feed in tariff fit for renewable electricity generation have become popular however their causal effect on renewable electricity generation remains subject to uncertainty we use instrumental variables to estimate the causal effect of fits on renewable electricity generation in 26 industrialized countries 1979 2005 we find that increasing the fit by one u s cent 2000 constant prices per kilowatt hour increases the percentage change in renewable electricity s share of the total by 0 11 points all else constant if a country implemented for a decade the sample mean fit of three u s cents the national share of renewable electricity would increase by 3 3 points which is more than the sample mean in addition to demonstrating that the fit is an effective way to increase renewable electricity generation our approach lays the foundation for future studies of the causal effects of renewable energy policies

uncertainty and incentives empirical work testing for a trade off between risk and incentives has had at best mixed success this article provides two simple reasons associated with subjectivity of performance appraisals why we might not expect to see any negative relationship both reasons relate to empirically observed problems associated with monitoring i supervisors sometimes bias their evaluations based on their personal feelings toward their subordinates and ii supervisors will sometimes offer evaluations that reduce their costs these aspects of monitoring are ignored in the standard model and can reverse the usual negative trade off between risk and incentives

economic development and co2 emissions a nonparametric panel approach we examine the empirical relation between co2 emissions per capita and gdp per capita during the period 1960 1996 using a panel of 100 countries relying on the nonparametric poolability test of baltagi et al baltagi b h hidalgo j li q 1996 a nonparametric test for poolability using panel data journal of econometrics 75 345 367 we find evidence of structural stability of the relationship we then specify a nonparametric panel data model with country specific effects estimation results show that this relationship is upward sloping nonparametric specification tests do not reject monotonicity but do reject the polynomial functional form which leads to the environmental kuznets curve in several studies

subjective performance appraisal and inequality aversion making use of a subjective performance appraisal system it is a well established fact that many supervisors tend to assess the employees too good leniency bias and that the appraisals hardly vary across employees of a certain supervisor centrality bias we explain these two biases in a simple theoretical model and discuss determinants of the size of the biases

optimal contracts for lenient supervisors we analyze optimal contracts in a hierarchy consisting of a principal a supervisor and an agent the supervisor is either neutral or altruistic towards the agent but his preferences are private information in a model with two supervisor types we find that the optimal contract may be very simple paying the supervisor a flat wage independent of his type and his evaluation of the agent s effort such a contract induces the neutral type of supervisor to report the agent s performance truthfully while the altruistic type reports favorably independent of performance accordingly overstated performance leniency bias may be the outcome of an optimal contract under informational asymmetries

an economic approach to influence activities in organizations members of organizations spend considerable time effort and ingenuity attempting to influence decision makers such influence activities may bring benefits to the organization but they also involve real costs this essay offers an economic rationale for such influence activity as representing rational self interested behavior in the presence of informational asymmetries and an analysis of how the design of the organization s structure and policies should respond to the incentives for attempting influence it is posited that information valuable for the organization s decision making is directly available only to members of the organization who have some personal stake in the decisions these individuals may then have an incentive to try to manipulate the information they develop and provide in order to influence the resulting decisions to their benefits this can be costly both in degrading the quality of decision making and in diverting the attention and effort of the organization s members from more productive activities the organization has three different methods it can employ to discourage excessive influence activities and to encourage more directly productive uses of time and effort it can limit access to decision makers and participation in decision making it can alter its decision making criteria to favor those performing well in productive activities and it can provide direct financial incentives to encourage the desired allocation of effort it is shown that an efficiently designed organization will use such financial incentives only as a last resort instead it will always first alter its decision participation policies and decisionmaking criteria

subjective performance measures in optimal incentive contracts objective measures of performance are seldom perfect in response incentive contracts often include important subjective components that mitigate incentive distortions caused by imperfect objective measures this paper explores the combined use of subjective and objective performance measures in respectively implicit and explicit incentive contracts naturally objective and subjective measures often are substitutes sometimes strikingly so we show that if objective measures are sufficiently close to perfect then no implicit contracts are feasible because the firm s fallback position after reneging on an implicit contract is too attractive we also show however that objective and subjective measures can reinforce each other if objective measures become more accurate then in some circumstances the optimal contract puts more weight on subjective measures because the improved objective measures increase the value of the ongoing relationship and so reduce the firm s incentive to renege we also analyze the use of subjective weights on objective performance measures and provide case study evidence consistent with our analyses

an analysis of the use of accounting and market measures of performance in executive compensation contracts prior research has provided useful insights into the structure of compensation plans and their incentive effects however one important limitation of these studies is the virtual absence of any cross sectional analyses of the attributes of compensation contracts 2 this absence is related in part to the problems associated with controlling for other factors that affect compensation that is compensation contracts are

energy paths in the european union a model based clustering approach this paper examines typical energy paths i e the intertemporal development of the energy mixes of the member states of the european union over 1971 2010 we apply model based clustering to detect major energy profiles and their compositional dynamics the seven identified clusters show typical combinations of energy carriers dominating the primary energy consumption of a country we find that countries tend to take a path towards higher quality energy mixes over time however path inertia and dependencies arise from both infrastructure and resource endowments higher energy quality profiles are usually associated with higher national income and energy use per capita providing some evidence of the existence of a national level energy ladder we also find convergence in energy intensity over time and a relationship between a country s own resources and import dependency

the existence of self enforcing implicit contracts implicit contracts are nontrivial nash equilibria to the post hiring trading game between a worker and the employer these are supported by intrafirm rather than labor market reputations the existence of an implicit contract that supports efficient trade is proved in a simple model

analysing the impact of renewable energy regulation on retail electricity prices abstract retail electricity prices have substantially increased in the last decade in the european union eu as a result of different regulations raising the concern of policy makers the growth in the support costs for electricity from renewable energy sources res e has often been singled out as a main driver of the increase in these prices the aim of this paper is to analyse the degree of influence of res e promotion costs on the evolution of the retail price of electricity in the eu member states the analysis is carried out for households as well as for industry with the help of a panel data econometric model our results show that the impact of renewable energy promotion costs on retail electricity prices is positive and statistically significant although relatively small differences across consumer types can be observed an increase of 1 in those costs induces an average increase of only 0 023 in industrial retail prices and 0 008 in the residential retail prices this impact on retail prices is mediated by the type of support scheme which is adopted with price based support instruments showing a greater effect than quantity based ones

managerial incentive problems a dynamic perspective the paper studies how a person s concern for a future career may influence his or her incentives to put in effort or make decisions on the job in the model the person s productive abilities are revealed over time through observations of performance there are no explicit output contingent contracts but since the wage in each period is based on expected output and expected output depends on assessed ability an implicit contract links today s performance to future wages an incentive problem arises from the person s ability and desire to influence the learning process and therefore the wage process by taking unobserved actions that affect today s performance the fundamental incongruity in preferences is between the individual s concern for human capital returns and the firm s concern for financial returns the two need be only weakly related it is shown that career motives can be beneficial as well as detrimental depending on how well the two kinds of capital returns are aligned it is well understood by now that informational externalities may place special demands on the organization of economic exchange simple price mediated markets will frequently fail in the presence of asymmetric information in that case more elaborate contractual arrangements have to be used as substitutes for the price system lately considerable effort has been devoted to the analysis of contracting under incomplete information with the objective to understand the range of economic institutions that emerge in response to the failure of the price system the analysis of moral hazard has played a prominent role in this development moral hazard problems arise when for some reason or another transacting parties cannot contract contingent on the delivery of the good for instance in buying labour services it may be that the amount of labour supplied is not directly observable precluding a simple exchange of wage for labour as a partial remedy to this problem an imperfect mutually observed signal about the supply of labour can be used as a proxy in the contract frequently output is taken as such a proxy the drawback is that output is often influenced by other factors than labour input which induce undesirable risk into the contract one is therefore faced with a tradeoff between allocating risk associated with incomplete observability and providing incentives for a proper supply of labour gaining insight into this tradeoff is important not only for understanding contracting in the small e g managerial incentive schemes but also because it is closely related to the fundamental tension between equity and efficiency in the society as a whole while our understanding of moral hazard has advanced a lot in past years it is clear that much work remains an important question that has received little attention until

an empirical investigation of the relative performance evaluation hypothesis the principal agent framework has become a widely used paradigm in accounting and economics for analyzing issues in performance evaluation management control and the design of incentive systems while recent work in experimental economics has begun to examine empirically some of the underlying assumptions and implications of agency theory see baiman and lewis 1989 and kirby forthcoming few precise hypotheses have been tested using real world or naturally occurring data one exception has been the empirical investigation of the relative performance evaluation rpe hypothesis agency theory suggests that there are benefits associated with evaluating agents on the basis of their relative performances when the agents performances are affected by a common shock term e g see diamond and verrecchia 1982 and holmstrom 1979 1982 specifically a relative performance based contract can remove the common shock term from an agent s performance which enables a better evaluation of the agent s actions

switching towards coal or renewable energy the effects of financial capital on energy transitions abstract does a country s stock of financial capital affect its ability to achieve energy transitions this paper uses data for up to 137 countries for the period 1998 2013 to investigate the importance of financial capital for changes in the use of each energy type i find that financial capital supports transition to more capital intensive energy types for high income countries financial capital facilitates transitions from fossil fuels to modern renewable energy sources especially wind both private credit from banks and domestic private debt securities support greater shares of wind energy for lower income countries financial capital supports progression from biomass towards fossil fuel energy sources such as coal i also find that countries with larger stocks of financial capital are more likely to move to more capital intensive electricity generation systems

an empirical analysis of sales force compensation plans among the array of direct and indirect methods of motivation and control available to the sales manager is sales force compensation in this article the authors summarize theoretical predictions from the economics marketing finance and accounting literatures on the structure of optimal sales force compensation plans guided by these insights they then construct empirical models to quantify the effect of various sales force factors firm and product factors and market factors on compensation using data from 286 firms in 39 industries the authors examine determinants of incentive components and total pay and the optimal horizon for incentive pay copyright 1992 by university of chicago press

the tenuous relationship between effort and performance pay abstract when an agent is offered performance related pay the incentive effect is not only determined by the shape of the incentive contract but also by the probability of contract enforcement we show that weaker enforcement may reduce the agent s effort but lead to higher powered incentive contracts this creates a seemingly negative relationship between effort and performance pay

integration of the sales force an empirical examination this article develops and tests a model of integration of a marketing function personal selling the model derived from transaction cost analysis as developed principally by williamson is formulated as a logistic function which is estimated with data from the electronic components industry as expected integration is associated with increasing levels of asset specificity difficulty of performance evaluation and the combination of these two factors contrary to the transaction cost model neither frequency of transactions nor interaction of specificity and environmental uncertainty is significantly related to integration the transaction cost model improves significantly upon the fit of a simple model relating integration to company size alone these results suggest that for studying transactions of this kind it is fruitful to view the firm as a governance structure

menu costs firm strategy and price rigidity abstract after controlling for chain specific effects higher menu costs are associated with a slight decrease in the probability of a price change and an increase in the size of a price change firm strategy is more influential in determining the incidence and magnitude of a price change

explaining government choices for promoting renewable energy abstract many advanced industrialized countries have in recent years experienced a significant expansion of electricity production from renewables yet we know quite little about the dynamics of the underlying policychoices in this area using new data on adoptions and changes in feed in tariff and green certificate schemes in 26 advanced industrialized countries over 20 years we examine both domestic driving forces as well as international determinants the findings suggest that three factors play a particularly important role in pushing countries towards market based support systems characteristics of the existing energy supply system a federalist structure of the political system and eu membership particularly noteworthy is the finding that higher shares of fossil and nuclear energy in the national energy supply as well as higher co 2 intensity of the economy do not as we had expected stand in the way of policies for supporting renewables in electricity production to the contrary they increase the likelihood of a country adopting such policies we also find however that higher economic growth and higher growth in solar and wind energy capacity tend to reduce the political appetite for reforms of existing schemes

the neoclassical firm under moral hazard we develop a model of the neoclassical firm under moral hazard with endogenous capital and employment and perfectly competitive capital labor and product markets we assume that effort becomes harder to measure as the firm gets larger and the exogenous parameters are affiliated the model explains why incentives decline but wages rise with firm size the mixed evidence on the risk reward tradeoff and the positive correlation between wages and profits in the long run incentives are increasing in risk via endogenous capital finally the model makes novel predictions about the relationship between incentives and labor market conditions

a test for parameter homogeneity in co2panel ekc estimations this paper casts doubt on empirical results based on panel estimations of an inverted u relationship between per capita gdp and pollution using a new dataset for oecd countries on carbon dioxide emissions for the period 1960 1997 we find that the crucial assumption of homogeneity across countries is problematic decisively rejected are model specifications that feature even weaker homogeneity assumptions than are commonly used furthermore our results challenge the existence of an overall environmental kuznets curve for carbon dioxide emissions

entrepreneurial orientation risk and incentives the case of franchising the standard principal agent model predicts a trade off in contract design between the protection against risk and incentive motivations distinguishing two types of risks we show that contrary to this traditional view the relationship between risk and incentives can be positive in franchise contracting this implies that the royalty rate decreases with the risk faced by the franchisee on the local market using a unique panel dataset combining french franchise and financial data we address this issue empirically alongside performance outcomes the data support the hypothesis of a negative relationship between risk and the royalty rate which contradicts the prediction of the standard agency theory furthermore our estimations provide evidence that chain performance increases with an adjusted royalty rate this paper has important implications for contract design showing that with increasing local market uncertainty and low risk aversion franchisors should reduce the royalty rate

salaries or piece rates on the endogenous matching of harvest workers and crops the objective of this paper is to determine whether the choice of payment schemes hourly vs piece rates is systematically related to the workers risk aversion and ability we derive the equilibrium relationship between agents risk aversion and ability and the power of incentives payment scheme in a market where many heterogeneous principals and agents are endogenously matched the equilibrium matching between principals and agents depends on the traits and is critical in determining the contract choice using confidential data from the national agricultural workers survey naws we find evidence of matching between agricultural workers and the riskiness of their jobs crops they harvest based on workers risk aversion and no matching based on ability when controlling for matching we find strong evidence that high risk averse workers choose hourly rates and low risk averse workers choose piece rates we also found that high ability types choose piece rates and low ability types choose hourly rates but the evidence is weaker jel j33 d82 q12

design of an economically efficient feed in tariff structure for renewable energy development abstract evidence suggests albeit tentatively that feed in tariffs fits are more effective than alternative support schemes in promoting renewable energy technologies rets fits provide long term financial stability for investors in rets which at the prevailing market price of electricity are not currently cost efficient enough to compete with traditional fossil fuel technologies on the other hand if not properly designed fits can be economically inefficient as is widely regarded to have been the case under the public utility regulatory policies act of 1978 purpa under purpa too high a guaranteed price led to the creation of so called purpa machines poorly performing generating units that could survive financially only because of heavy subsidies that came at the expense of retail customers similarly because of their adverse impacts on retail electricity rates german fits have been subject to increasing political pressure from utilities and customers in this paper we propose an innovative two part fit consisting of both a capacity payment and a market based energy payment which can be used to meet the renewables policy goals of regulators our two part tariff design draws on the strengths of traditional fits relies on market mechanisms is easy to implement and avoids the problems caused by distorting wholesale energy markets through above market energy payments the approach is modeled on forward capacity market designs that have been recently implemented by several regional transmission organizations in the usa to address needs for new generating capacity to ensure system reliability

household energy mix in uganda abstract this paper presents evidence that household energy use in uganda conforms to the energy ladder theory as household income increases solid and transitional fuel use evolves in an inverse u manner while electricity consumption shows a direct relationship with income public infrastructure provision income and education are the key variables which can be targeted to reduce household dependence on solid fuels while increasing non solid fuel use while education and public infrastructure have varying impacts on rural and urban households energy mix these variables generally reduce rudimentary fuel use and increase modern fuel consumption timely investment in electricity infrastructure is necessary to cater for burgeoning electricity demand as households become affluent strategies for reforestation dissemination of improved cookstoves relieving supply side constraints for modern fuels and staggered payment options to lower the cost of entry for modern fuels can improve ugandan households energy security

rule of law and the resource curse abundance versus intensity we examine the resource curse using new data on historic resource stocks and an improved econometric methodology the paper distinguishes between resource abundance stocks and extractive intensity flows focusing on relationships between resources and rule of law previously unavailable information on past resource stocks is estimated we find that economically large initial natural resource stocks are associated with subsequent lower levels of rule of law and do not directly affect growth while raw resource exports do not have a significant effect on rule of law when stocks are included in the analysis but do affect average growth rates sample size is maximized through the use of an emis expectation maximization with importance sampling algorithm to replace missing data minimizing the bias and inefficiency associated with listwise deletion which commonly eliminates half or more of the available data in this setting

price stickiness empirical evidence of the menu cost channel abstract a leading explanation in the economic literature is that monetary policy has real effects on the economy because firms incur a cost when changing prices using a unique database of cost and retail price changes we find that variation in menu costs results in up to 13 3 fewer price increases we confirm that these effects are allocative and have a persistent impact on both prices and unit sales we provide evidence that the menu cost channel operates only when cost increases are small in magnitude which is consistent with theory and provides the first empirical evidence of boundary conditions

the role of promotion in inducing specific human capital acquisition workers routinely carry out activities that increase their productivity with their current employer for which they are not directly compensated for example a worker may be asked to develop relationships with clients or shop floor staff or he may develop a better understanding of how his firm operates firmspecific human capital of this type is difficult to quantify so that it is likely to be difficult to directly compensate the worker for its acquisition this paper is concerned with designing compensation schemes for employees to induce them to collect nonverifiable firm specific human capital if firms develop reputations for fairly compensating workers for skill collection the vagueness of these skills may not provide a significant incentive problem i consider the case where firms do not have the opportunity to develop reputations as a result the acquisition of human capital is subject to a dual moral hazard problem first noted in kahn and huberman 1988 first a worker only collects skills if there is a promise of a higher wage if he does so second the employer has an incentive to claim that the worker has not collected these skills even when he in fact has in order to save on wage costs so on the one hand it is difficult to repay the worker after skills are collected as the firm has an incentive to renege however the worker cannot be repaid before collecting skills as he has no subsequent incentive to collect them following the institutional literature i assume that the firm can commit to a labor contract which attaches wages to different tasks the principal purpose of the paper is to show that the firm can use this ability to commit to a wage scale for different tasks to induce a worker to collect firm specific human capital in the presence of this dual moral hazard problem where the worker is rewarded for skill acquisition by promotion to another job assume that a worker can be assigned to one of two jobs d and

tournaments with prize setting agents in some tournaments it is the contestants themselves who determine reward allocation union members bargain over wage distribution and some firms allow self managed teams to freely determine internal resource allocation incentive structure and division of labor we analyze and test experimentally a tournament where heterogeneous agents determine the spread between winner prize and loser prize we investigate the relationship between prize spread uncertainty heterogeneity and effort we find that a large prize spread is associated with a low degree of uncertainty and a high degree of heterogeneity and that heterogeneity triggers effort by and large our real effort experiment supports the theoretical predictions

will history repeat itself economic convergence and convergence in energy use patterns in this paper a difference in differences estimator on panel data for 30 developing and 21 industrialized countries is employed over the period 1971 2005 to examine how patterns of energy use characterized by the consumption of primary energy carriers sectoral energy use and carbon emissions are changing in the process of economic development for the average developing country in our sample the results indicate that economic catch up has been accompanied by above average growth of the use of most primary energy carriers the consumption of final energy in most sectors and total co2 emissions for industrialized countries we find that economic growth is partially decoupled from energy consumption and that above average rates of economic growth were accompanied by larger improvements in energy efficiency these results emphasize the need to identify the relevant engines of economic growth their implications for energy use and possibilities to achieve low carbon growth centered on productivity and efficiency improvements rather than on capital accumulation

subjective evaluations with performance feedback this paper models two key roles of subjective performance evaluations their incentive role and their feedback role the paper shows that the feedback role makes subjective pay feasible even without repeated interaction as long as there exists some veri able measure of performance it also shows that while subjective pay is helpful it cannot achieve full e ciency however fully e cient incentives are achievable if the rm can commit to a forced distribution of evaluations and employs a continuum of workers with a small number of workers a forced distribution is valuable only if the veri able measure is poor

the provision of incentives in firms i ncentives are the essence of economics despite many wide ranging claims about their supposed importance there has been little empirical assessment of incentive provision for workers the purpose of this paper is to critically overview existing work on the provision of incentives since the interests of workers and their employers are not always aligned a large theoretical literature has emphasized how firms design compensation contracts to induce employees to operate in the firm s interest this literature has reached into many areas of compensation and has pointed to a multitude of different mechanisms that can be used to induce workers to act in the interests of their employers these include piece rates options discretionary bonuses promotions profit sharing efficiency wages deferred compensation and so on my objective here is to evaluate this literature in the light of a growing empirical literature on compensation where possible i will address the literature from two perspectives first an underlying assumption of this literature is that individuals respond to contracts that reward performance accordingly i consider whether agents behave in this way and whether these responses are always in the firm s interest second i address whether firms write contracts with these responses in mind in other words do contracts look like the predictions of the theory incentives are provided to workers

diversifying the brazilian electricity mix income level the endowment effect and governance capacity abstract low and middle income countries are usually trapped by their natural resource abundance and thus have little opportunity to diversify their electricity matrix on the other hand in high income countries new electricity sources have been growing faster regardless of their resource endowments as income grows countries should have more opportunities to develop new technologies thus the evolution of technologies to generate electricity should lead to a new mix of fuel consumption along the steps of an imaginary electricity ladder from the more traditional to the more advanced and cleaner technologies notwithstanding the income effect the endowment effect could hinder the diversity of electricity sources in this context we examine whether or not brazil has been able to diversify its electricity mix with respect to income growth by breaking what we called the endowment trap based on an economic model developed in this research we found evidence that brazil has succeeded in breaking its hydroelectric dependency but has not eliminated the polluting sources

executive compensation and principal agent theory the empirical literature on executive compensation generally fails to specify a model of executive pay on which to base and test hypotheses regarding its determinants in contrast this paper analy

a near rational model of the business cycle with wage and price inertia this paper presents a model in which insignificantly suboptimal behavior causes aggregate demand shocks to have significant real effects the individual loss to agents with inertial price wage behavior is second order in terms of the parameter describing the shock while the effect on real economic variables is first order thus significant changes in business activity can be generated by anticipated money supply changes provided that some agents are willing to engage in nonmaximizing behavior which results in small losses

uncertainty task environment and organization design an empirical investigation the paper addresses two broad research questions 1 how do internal uncertainty associated with the task environment and external uncertainty arising from market volatility impact organization design 2 what are the relationships among various elements of organization design delegation of decision making incentives monitoring and internal labor market practices promotion training employment security we expand on prendergast 2002a who challenged the conventional view of a tradeoff between risk and incentives and build a single unified framework for answering our two research questions using a uniquely rich dataset that contains detailed information about the task environment of core employees and organization design at the individual group and firms levels in 530 minnesota firms in the mid 1990s we first find support for prendergast s key argument that internal uncertainty over which employees have control affects directly the allocation of decision making and only indirectly incentives via allocation of decision making this confirms similar findings by foss and laursen 2005 devaro and kurtulus 2010 and shi 2011 we also find that internal uncertainty has much impact on organization design through the choice of delegation of decision making at the employee level less so at the group level and very little at the firm level whereas external market uncertainty has little effect on organization design especially at the individual and group level decision making monitoring various internal labor market practices and incentives are strongly related to each other through substitution and complementarity

menu costs firm size and price rigidity abstract if menu costs have a non negligible lump sum component and with larger firms having greater benefits from price adjustments then larger firms will change price more frequently than smaller firms data from new zealand firms support this hypothesis price duration decreases as firm size increases ordered probit analysis indicates the effect comes primarily from larger firms being more likely than smaller firms to raise price in response to a demand or cost increases

what do we know about the study of distributed generation policies and regulations in the americas a systematic review of literature abstract policy makers are increasingly in search for evidence based solutions for meeting contemporary challenges of energy services that are both low carbon and sustainable one of the emerging trends are policies and regulations that incent distributed electricity generation dg the question that this article addresses is what is the current state of the study of these policies or regulations in the americas the focus on the americas was chosen because the article is part of a larger research project that explores regulations for dg in brazil and canada this article uses a non traditional means for synthesizing academic work systematic literature review to explore the current state of peer reviewed publications on the subject it is a means of transparently locating evaluating and synthesizing information to avoid bias in data collection in total 87 articles were included in the review climate change is the main driving force for dg as identified in the articles job creation or the green economy was cited as a motivating factor more strongly in north america while in the southern countries the issue of diversifying the energy mix and avoiding infrastructure costs was more pronounced many articles dealt with the issue of mechanisms for incenting dg and over half of these focused on aspects of feed in tariffs incentive mechanisms vary depending on policy goals of the jurisdictions with renewable portfolio standards being more popular in the u s the review showed that there is little emphasis on the social impacts and benefits of the regulations or policies and that specific urban challenges and local governance is not widely investigated pointing to a need for future study in these areas

comparison of energy transitions in the united states and developing and industrializing economies summary we compare the energy transitions of the united states with several developing and industrializing economies the analysis reveals three important differences between trends first the developing world experiences energy related transitions at lower levels of income with faster rates of change in conditions over time and in a more simultaneous fashion than that of the united states second over similar income ranges i e segments of economic growth current developing economies are using less energy per capita than the united states did historically finally this more efficient economic growth translates into lower systemic environmental impact per capita than that of the united states

contract choice in modern agriculture cash rent versus cropshare e conomists have expended enormous effort examining the rationale for various contractual arrangements in agriculture particularly sharecropping while economists have made considerable theoretical efforts to understand agricultural contracts few empirical studies have been undertaken the dearth of empirical analyses of agricultural contracts is particularly striking for modern western agriculture this is an important omission not only because the existing empirical work tends to focus on the question of efficiency but also because the theoretical models tend to examine contracts that bear little resemblance to those found in the united states today

the magnitude of menu costs direct evidence from large u s supermarket chains we use store level data to document the exact process of changing prices and to directly measure menu costs at five multistore supermarket chains we show that changing prices in these establishments is a complex process requiring dozens of steps and a nontrivial amount of resources the menu costs average 105 887 year per store comprising 0 70 percent of revenues 35 2 percent of net margins and 0 52 price change these menu costs may be forming a barrier to price changes specifically 1 a supermarket chain facing higher menu costs due to item pricing laws that require a separate price tag on each item changes prices two and one half times less frequently than the other four chains 2 within this chain the prices of products exempt from the law are changed over three times more frequently than the products subject to the law in principle fixed costs of changing prices can be observed and measured in practice such costs take disparate forms in different firms and we have no data on their magnitude so the theory can be tested at best indirectly at worst not at all alan blinder 1991 p 90

understanding the energy gdp elasticity a sectoral approach abstract this paper uses per capita data for 132 countries over 1960 2010 to estimate elasticities of sectoral energy use with respect to national gross domestic product gdp we estimate models in both levels and growth rates and use our estimates to sectorally decompose the aggregate energy gdp elasticity our estimates show that residential energy use is very inelastic to gdp if primary solid biofuels are counted in energy use tallies especially at low income levels residential use of electricity is more tightly linked to gdp as is energy use by the transportation industrial and services sectors agriculture typically accounts for a small share of energy use and has a modest energy gdp elasticity the aggregate energy gdp elasticity tends to be higher for countries at higher income levels in large part because traditional use of primary solid biofuels is less important gasoline prices winter temperature population and land area are among other factors influencing sectoral energy use

integrating sustainability into city level co2 accounting social consumption pattern and income distribution abstract from a sustainability perspective city level co2 emissions require reconsiderations correspondingly the economy environment society nexus should be incorporated into city scale co2 accounting therefore in this study the semi closed io model is integrated with a hem to calculate co2 emissions arising from the social consumption pattern and income distribution and to explore economic drivers behind co2 variations this method is applied to a case study of beijing result demonstrate that beijing in 2012 witnessed something different from that in 2005 1 co2 emissions centred in the internal linkages of a broader class of consumption terms with high economic output mainly driven by interprovincial exports 2 imports increasingly helped decarbonize the mixed net forward and backward co2 linkages of consumption items and 3 income driven co2 emissions excluding demand side parts persisted which were more obvious on the supply side where households have more economy wide effects besides urban households played an essential role in household wide co2 reductions this paper ended with corresponding conclusions policy implications and directions for future work

do renewable energy policies reduce carbon emissions on caps and inter industry leakage abstract in a parsimonious two sector general equilibrium model we challenge the widely held tenet that within a cap and trade system renewable energy policies have no effect on carbon emissions if the cap does not capture all sectors we demonstrate that variations of a renewable energy subsidy change aggregate carbon emissions through an inter industry leakage effect we decompose this effect into intuitively intelligible components that depend in natural ways on measurable elasticity parameters raising the subsidy always reduces emissions if funded by a lump sum tax reinforcing recent findings that tightening environmental regulation can cause negative leakage however if the subsidy is funded by a levy on electricity it can increase emissions these results provide a valuable basis for an informed design of renewable energy policies and an accurate assessment of their effectiveness we highlight how a state of the art statistic used by governments to gauge such effectiveness virtual emission reductions is biased because inter industrial leakage effects are not captured

regulating nitrogen pollution with risk averse farmers under hidden information and moral hazard we consider a model of pollution regulation for a risk averse farmer involving hidden information moral hazard and risk sharing the representative farmer faces a production risk originating from nitrogen leaching and privately observes the soil capacity in retaining nitrogen only after the regulation contract is signed the latter specifies a transfer and a nitrogen quota whose decomposition by the farmer among different production stages is unknown to the regulator we first characterize the optimal solution to the regulator s problem the sequential decision model is estimated on french crop production data and the results are used to calibrate and simulate the optimal contract

aggregation and optimization with state dependent pricing the literature on the aggregation of s s policies has ignored the impact of aggregate behavior on the individual s optimization problem in the case of pricing the feedback effects are clear not only do pricing strategies determine the evolution of the price level but the evolution of the price level also influences the optimal pricing strategies in this paper we provide a consistent treatment of aggregation and optimization we use this model to analyze three issues in the menu cost pricing literature the relationship between strategic complementarity and the real effects of money the relationship between the variance of the money supply and the correlation between money and output and the relationship between the cost of price adjustment and the size of price adjustment questions concerning the dynamics of aggregate variables such as prices employment investment and consumption represent the core of business cycle analysis one striking feature of these variables is the radical difference between properties of these aggregates and the nature of the individual behavior that underlies them the behavior of a firm s prices investment and employment and the behavior of an individual s consumption all involve frictional elements that lead to discrete adjustment at the microeconomic level heterogeneity among individuals however tends to smooth the behavior of the corresponding aggregates in recent years a large body of research has developed to examine the manner in which microeconomic frictions influence aggregate dynamics one of the centerpieces of this research has been the s s model developed by arrow harris and marschak 1951 the key element of this model is the state dependence of individual decisions agents act when a state variable crosses some critical threshold which balances the cost and benefits of adjustment the aggregate implications of this form of microeconomic behavior have been analyzed by blinder 1981 caplin 1985 and mosser 1991 in the context of inventory dynamics by caplin and spulber 1987 caballero and engel 1991 1993 and caplin and leahy 1991 in the context of prices and by bertola and caballero 1990 caballero 1993 and eberly 1994 in the context of con sumer durables one of the most limiting aspects of these models is that they focus exclusively on the impact that microeconomic inertia has on aggregate dynamics they 1we would like to thank michael harrison loannis karatzas john leahy sr andreu mas colell a co editor and four anonymous referees for helpful discussions and comments and the national science foundation and the sloan foundation for financial support

incentives equality and contract renegotiations theory and evidence in the chinese banking industry renegotiation plays an important role in contract theory but the empirical study of renegotiation is almost non existent in the literature using a unique dataset from the chinese banking industry we find that the large majority of managerial incentive contracts are renegotiated after performances are realized we develop a model of contract renegotiation where supervisors and managers sign incentive contracts and then renegotiate them in the unique equilibrium of the model incentive contracts are almost always renegotiated ex post even though renegotiation is fully anticipated incentive contracts affect performance the predictions of the model find strong support from our empirical results

demand pull instruments and the development of wind power in europe a counterfactual analysis renewable energy technologies are called to play a crucial role in the reduction of greenhouse gas emissions since most of these technologies did not yet reach grid parity public policies have been implemented in order to foster their deployment the approach that has been privileged in europe is the demand pull approach that aims at creating a demand for these new technologies and at stimulating their diffusion this paper examines the effect of demand pull policies on the diffusion of onshore wind power technology in six european countries denmark france germany italy portugal and spain in a first step a micro founded model of diffusion is calibrated in order to replicate the observed diffusion of wind power in these six countries in a second step a counterfactual analysis is conducted by investigating several scenarios by taking into account the complex self sustained dynamics of diffusion and the learning spillovers that operate in the wind power sector we can derive several insights about demand pull policies first the impact of a demand pull policy on the diffusion of wind power is determined by the stage at which it comes to support it the effect seems to be stronger at the beginning of the diffusion second international spillovers do operate in the wind power sector these international spillovers however are not strong enough to foster the diffusion of wind power in a country having no demand pull support we can derive from these two statements that a strategy consisting in not implementing any demand pull policy with the expectation that international spillovers will reduce the cost of wind power and foster the diffusion of the technology that then shall become competitive is not a good option for a country targeting a high share of wind power in its energy mix

the output inflation trade off when prices are costly to change the output inflation trade off is investigated in a rational expectations equilibrium economy in which costly price setting makes it inefficient for agents to vary their prices at every instant it is shown that sticky prices are not some exogenous source of output fluctuation but result from the monetary policy process an economy with slow and counterinflationary money growth exhibits staggered changes in sticky prices as assumed in some new keynesian analyses an economy with fast money growth and a high degree of monetary accommodation exhibits either flexible prices or bunched frequently changing sticky prices

global energy transitions and political systems abstract transitioning from one form of energy to another has led to social change in areas such as production methods quality of life and labor productivity in addition there is a relationship between this social change and the emergence of different types of political systems surprisingly there are not many studies on the relationship between energy transitions and changes in political systems the purpose of this paper is to demonstrate that the transition from one form of energy to another has historically determined the type of political system and that this causal relationship has evolved through the ages a three stage approach was used in this study to examine this relationship in the past and present and to predict coming changes in the future the main finding is that from the foraging period to the oil age energy has been a factor in determining political systems however with the expansion of energy trade between nations and the emergence of new technology options the situation has been reversed political systems have now become a determinant of energy transitions also even democratic countries have been unwilling to transition to new forms of energy preferring instead to maintain fossil fuel based energy systems

renewable energy and politics a systematic review and new evidence abstract this paper reviews the literature in the intersection of renewable energies and politics adopting a multidisciplinary social sciences perspective we begin by analyzing the recent literature dealing with renewable energies and politics illustrating the analysis with bibliometric data the search protocol revealed 853 contributions dated from 1998 then we focus on the 186 contributions approached from a social sciences perspective establishing a taxonomy to classify the contributions into the main issues covered we identify contributions dealing with governance with public acceptance with markets and prices and with political or policy determinants of renewable energies in an empirical application we show that more democratic countries tend to invest more in renewable energies taking into account other determinants e g income energy dependence pollution emissions of this investment

contracting with self esteem concerns it is widely accepted in social psychology that the need to maintain and enhance self esteem is a fundamental human motive we incorporate this factor into an otherwise ordinary principal agent framework and examine its impact on the optimal incentive scheme and the agent s behavior especially focusing on the form of intrapersonal strategy known as self handicapping incorporating self esteem concerns into a contracting situation yields an implication that runs counter to conventional wisdom that is the standard tradeoff between risk and incentives may break down i e more uncertainty reduces agency cost and hence results in stronger incentives in the presence of self esteem concerns this is because uncertainty mitigates the need for self handicapping this result provides a possible reason for why we do not empirically observe this tradeoff in a robust manner we present an intuitive condition for this anomaly to arise and provide a set of testable implications the present framework also reveals why and how team production can be made more profitable by providing an explanation for the increasing popularity of team production finally this simple logic is applied to identify additional implications for the hidden costs of external enforcers such as evaluation and monitoring which are discussed extensively in social psychology

holiday price rigidity and cost of price adjustment the thanksgiving christmas holiday period is a major sales period for us retailers due to higher store traffic tasks such as restocking shelves handling customers questions and inquiries running cash registers cleaning and bagging become more urgent during holidays as a result the holiday period opportunity cost of price adjustment may increase dramatically for retail stores which should lead to greater price rigidity during holidays we test this prediction using weekly retail scanner price data from a major midwestern supermarket chain we find that indeed prices are more rigid during holiday periods than non holiday periods for example the econometric model we estimate suggests that the probability of a price change is lower during holiday periods even after accounting for cost changes moreover we find that the probability of a price change increases with the size of the cost change during both the holiday as well as non holiday periods we argue that these findings are best explained by higher price adjustment costs menu cost the retailers face during the holiday periods our data provides a natural experiment for studying variation in price rigidity because most aspects of market environment such as market structure industry concentration the nature of long term relationships contractual arrangements etc do not vary between holiday and nonholiday periods we therefore are able to rule out these commonly used alternative explanations for the price rigidity and conclude that the menu cost theory offers the best explanation for the holiday period price rigidity

adoption of solar and wind energy the roles of carbon pricing and aggregate policy support abstract this paper analyzes the roles of policies and preferences in national adoption of solar and wind energy technologies we use cross sectional and panel regressions for both the european union and a broader international sample we find that countries that price carbon emissions have gone on to adopt more solar and wind energy the aggregate level of policy support measured in euros per megawatt hour appears to have been important for solar energy adoption we also find that solar energy adoption has been larger in countries with higher proportions of people concerned about climate change in addition we assess the effects of other key explanators including financial system size and income levels

small menu costs and large business cycles a macroeconomic model of monopoly i introduction the conflict between modern neoclassical and traditional keynesian theories of the business cycle centers upon the pricing mechanism in neoclassical models prices are fully flexible they represent the continuous optimization of economic agents and the continuous intersection of supply and demand in keynesian models prices are often assumed to be sticky they do not necessarily equilibrate all markets at all times one of the reasons for the resurgence of the equilibrium approach to macroeconomics has been the absence of a theoretical underpinning for this keynesian price stickiness this note shows that sticky prices can be both privately efficient and socially inefficient the business cycle results from the suboptimal adjustment of prices in response to a demand shock to the extent that policy can stabilize aggregate demand it can mitigate the social loss due to this suboptimal adjustment in some keynesian models prices are simply exogenously fixed 2 in others agents must set their prices in advance of the transaction date the act of altering a posted price is certainly costly these costs include such items as printing new catalogs and informing salesmen of the new price yet these menu costs are small and therefore generally perceived as providing only a weak foundation for these fixed price models however this inference is flawed small menu costs can cause large welfare losses the claim that price adjustment costs are small does not rebut the claim that they are central to understanding economic fluctuations

uncertainty entrepreneurship and sharecropping in india this study attempts to explain the coexistence of different farm lease arrangements in terms of the varying significance of entrepreneurial functions in india crop sharing arrangements are common in areas of relative economic certainty with very little scope for decision making for example for product and factor substitution and where the entrepreneurial profit is low fixed cash rents are common in situations of high uncertainty where the scope for decision making is significant or where the crops are highly profitable efficiency considerations predominate in areas of sharecropping favoring a smaller farm size whereas under high uncertainty large size is favored for reducing risk

economic growth and transitions between renewable and nonrenewable energy resources abstract we study transitions between nonrenewable and renewable energy forms at different development stages of an economy it is shown that in the historical context the emphasis on energy production may evolve from renewables to nonrenewables and back to renewables typically both energy forms are used simultaneously along the equilibrium path nonrenewable resource consumption may increase and their price decrease an inverted u relation between carbon emissions and income level may follow even without environmental policy

the use of performance measures in incentive contracting the strength of incentives used in an organization and the productivity of employees that results from these incentives depend to a large degree on the characteristics of the performance measures available to the organization some employees work under high powered explicit incentive contracts while others have no explicit incentive contracts at all the ability of agency theory to predict the pattern of incentive provision in organizations has not been very impressive and the divergence between the prescriptions of agency theory and the actual practice of firms has been widely noted this paper along with both other papers in this session edward p lazear 2000 canice prendergast 2000 attempts to fill some of the gap between theory and practice i examine the characteristics of performance measures those data on which explicit incentive contracts are based to understand how firms use incentive contracting and to predict the use of incentives in practice
