income dispersion and counter cyclical markups recent advances in measuring cyclical changes in the income distribution raise new questions how might these distributional changes affect the business cycle itself we show how counter cyclical income dispersion can generate counter cyclical markups in the goods market without any preference shocks or price setting frictions in recessions idiosyncratic labor productivity shocks raise income dispersion lower the price elasticity of demand and increase imperfectly competitive firms optimal markups the calibrated model explains not only many cyclical features of markups but also cyclical and long run patterns of standard business cycle aggregates

stochastic lot sizing manufacturing under the ets system for maximisation of shareholder wealth abstract the issues of carbon emission and global warming have increasingly aroused worldwide attention in recent years despite huge progresses in carbon abatement few research studies have reported on the impacts of carbon emission reduction mechanisms on manufacturing optimisation which often leads to decisions of environmentally unsustainable operations and misestimation of performance this paper attempts to explore carbon management under the carbon emission trading mechanism for optimisation of lot sizing production planning in stochastic make to order manufacturing with the objective to maximise shareholder wealth we are concerned not only about the economic benefits of investors but also about the environmental impacts associated with production planning numerical experiments illustrate the significant influences of carbon emission trading pricing and caps on the dynamic decisions of the lot sizing policy the result highlights the critical roles of carbon management in production planning for achieving both environmental and economic benefits it also provides managerial insights into operations management to help mitigate environmental deterioration arising from carbon emission as well as improve shareholder wealth

the low skill trap recently it has become popular to argue that certain workers have fallen into a trap in which they have poor skills few job opportunities and a low return on training while others have not this paper demonstrates how such a trap can occur within a simple matching model with rent sharing rent sharing diminishes the worker s incentive to acquire skills however since firms also benefit from training rent sharing likewise induces job creation the subsequent improved matching prospects may offset the initial disincentive to invest however for this mechanism to be effective firms and workers must coordinate their actions if they do not the trap occurs

unionisation structures and innovation incentives this paper examines how dierent unionisation structures aect rms innovation incen tives and industry employment we distinguish three modes of unionisation with increasing degree of centralisation 1 decentralisation where wages are determined independently at the rm level 2 coordination where one industry union sets individual wages for all rms and 3 centralisation where an industry union sets a uniform wage rate for all rms while rms investment incentives are largest under centralisation investment in centives are non monotone in the degree of centralisation decentralisation carries higher investment incentives than coordination labour market policy can spur innovation by decentralising unionisation structures or through non discrimination rules

precision of dichotomous choice contingent valuation welfare measures some simulation results the purpose of this research is to examine the roles of individuals heterogeneous economic factors and model misspecification in dichotomous choice contingent valuation welfare measurement willingness to pay for an improvement of environmental quality is studied simulation results indicate that the precision of welfare estimates increases with individuals income levels and decreases with the price of the quality related good the dependence of the consumption of the quality related good on the environmental quality also affects the reliability of welfare estimates

ecological modernization in the electrical utility industry an application of a bads goods dea model of ecological and technical efficiency abstract newly developed data envelopment analysis techniques permit simultaneous consideration of good and bad outputs in evaluating efficiency we use these techniques to determine joint ecological and technical efficiencies of the 437 largest fossil fueled electricity generating plants in the united states utilizing the epa s e grid and clean air markets databases and drawing on ecological modernization theory we evaluate whether innovations in organizational practices and technological solutions help achieve joint technical and environmental performance efficiencies

estimating local welfare generated by an nfl team under credible threat of relocation this study offers the opportunity to examine the welfare contribution of the minnesota vikings to minnesota households in the context of a credible threat of team relocation we find the credibility of the threat of relocation is essential to providing unbiased estimates of welfare this study utilizes contingent valuation methodology cvm and a random utility model rum to analyze minnesotans decision making mechanisms for supporting a new stadium initiative while previous studies have attempted to measure the welfare associated with a sports franchise we develop and discuss bias that may be imparted to estimates when the researcher fails to calculate a choke price further we develop an unbiased approach to identify welfare when respondents perceive a risk of losing the franchise the range of welfare contribution by the vikings to households in minnesota is 445 3 million to 1 571 3 million according to a 95 confidence interval based on our study

managerial leverage is limited by the extent of the market hierarchies specialization and the utilization of lawyers human capital abstract this paper examines the role of hierarchies in the organization of human capital intensive production we develop an equilibrium model of hierarchical organization and provide empirical evidence based on confidential data on thousands of law offices the equilibrium assignment of individuals to hierarchical positions varies with the degree of field specialization which increases as the extent of the market increases as individuals knowledge becomes narrower but deeper managerial leverage the number of workers per manager optimally increases to exploit this depth consistent with our model the share of lawyers who work in hierarchies and the ratio of associates to partners increase as market size increases and lawyers field specialize other results provide evidence against alternative interpretations that emphasize unobserved differences in the distribution of demand or firm size effects and lend additional support to the view that in legal services hierarchies help exploit increasing re

reaching for the stars who pays for talent in innovative industries innovative firms need to hire and motivate highly talented workers this article connects the potential returns to innovation to the structure of compensation for skilled employees we show that the software firms that operate in software sectors with high potential upside gains to innovation pay more to star workers than do other firms that operate in stable markets firms operating in product domains with highly skewed positive returns pay employees more in up front starting salaries and offer higher compensation growth the large estimated effects on earnings are robust to the inclusion of a wide range of controls for worker and firm characteristics

benefit estimates for landscape improvements sequential bayesian design and respondents rationality in a choice experiment a multi attribute stated preference approach is used to value low and high impact actions on four major landscape components addressed by the rural environment protection scheme in ireland several methodological issues are addressed the use of prior beliefs on the relative magnitudes of parameters standardized description of different levels of landscape improvements via image manipulation software adoption of efficiency increasing sequential experimental design and sensitivity of benefit estimates to inclusion of responses from irrational respondents results suggest that bayesian design updating delivers significant efficiency gains without loss in respondent efficiency and estimates are upward biased when irrational respondents are included

some models for estimating technical and scale inefficiencies in data envelopment analysis in management contexts mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best in this capacity mathematical programming serves as a planning aid to management data envelopment analysis reverses this role and employs mathematical programming to obtain ex post facto evaluations of the relative efficiency of management accomplishments however they may have been planned or executed mathematical programming is thereby extended for use as a tool for control and evaluation of past accomplishments as well as a tool to aid in planning future activities the ccr ratio form introduced by charnes cooper and rhodes as part of their data envelopment analysis approach comprehends both technical and scale inefficiencies via the optimal value of the ratio form as obtained directly from the data without requiring a priori specification of weights and or explicit delineation of assumed functional forms of relations between inputs and outputs a separation into technical and scale efficiencies is accomplished by the methods developed in this paper without altering the latter conditions for use of dea directly on observational data technical inefficiencies are identified with failures to achieve best possible output levels and or usage of excessive amounts of inputs methods for identifying and correcting the magnitudes of these inefficiencies as supplied in prior work are illustrated in the present paper a new separate variable is introduced which makes it possible to determine whether operations were conducted in regions of increasing constant or decreasing returns to scale in multiple input and multiple output situations the results are discussed and related not only to classical single output economics but also to more modern versions of economics which are identified with contestable market theories

comparative advantage learning and sectoral wage determination we develop a model in which a worker s skills determine the worker s current wage and sector the market and the worker are initially uncertain about some of the worker s skills endogenous wage changes and sector mobility occur as labor market participants learn about these unobserved skills we show how the model can be estimated using nonlinear instrumental variables techniques we apply our methodology to study wages and allocation of workers across occupations and industries using individual level panel data from the national longitudinal survey of youth we find that high wage sectors employ high skill workers and offer high returns to workers skills

testing rent sharing using individualized measures of rent evidence from domestic helpers wing suen the market for resident domestic helpers offers a rare opportunity where the surplus from employment relationship can be quantitatively measured for each individual employee using the difference between employer s cost of time and employee s wage as a measure of rent it is found that wages for domestic helpers are positively related to rent however the apparent sharing of rent is better explained by matching than by efficiency wage models rent sharing is observed even in households where monitoring or turnover costs are low rent sharing is not observed among newly arrived foreign domestic helpers whose ability remains to be revealed jel j41 i introduction this article studies the pattern of wages for resident domestic helpers in hong kong no one would lure economists into paying attention to this arcane labor market were it not for one feature of the market for housework a measure of employment rent can be plausibly assigned to each individual employee having an individualized measure of rent at the worker level instead of a general measure at the firm level will shed considerable light on the large and growing literature of rent sharing in wage determination since 1975 the hong kong government has allowed the importation of foreign domestic helpers into the territory because of large wage differences between hong kong and some of its asian neighbors the program is highly popular the census and statistics department 1995 estimates that 92 700 households or 5 6 of all domestic households in hong kong employed domestic helpers in 1993 the figure is even more dramatic for high income households 44 of households with monthly income of over hk 50 000 had one or more domestic helpers 1 one consequence of the availability of market procured housework is that women who employ helpers have more time for market work in suen 1994 i estimate that the probability of labor force participation among married women who had domestic helpers is 22 percentage points higher than that for women without domestic help other things equal if hiring a helper enables a married woman to engage in market work then a plausible measure for the rent or surplus from this employment relationship is the difference between the woman s wage and her helper s wage if a woman with a domestic helper decides to stay home nonetheless the size of the surplus can be measured by the difference between the shadow value of leisure and the helper s wage wage information is readily available from census data and shadow wages can be estimated using standard techniques this article utilizes this rare opportunity to impute a measure of rent for each employer employee pair studying how the wages of domestic helpers vary wi th the magnitude of rent will provide direct evidence for rent sharing in the labor market there is a large literature which documents the fact that the characteristics of the employer such as industry affiliation and firm size are significantly correlated with the employees wages krueger and summers 19881 brown and medoff 1989 groshen 1991 helwege 1992 and many others offer convincing evidence that inter industry wage differentials and employer wage effects exist rent sharing is often invoked to account for such wage patterns however few studies in the literature offer a plausible account for the existence of or a measure for the size of the rent that is supposedly shared 2 at the industry level dickens and katz 1987 use variables such as concentration ratio capital labor ratio research and development expenditures and average rate of return on capital as covariates in wage equations these variables provide at best an indirect and error prone measure of employment rent campbell 1993 makes use of firm level characteristics instead of industry characteristics but t here is no information on profits in his firm level data

incentives learning and compensation a theoretical and empirical investigation of managerial labor contracts this article analyzes properties and implications of multiperiod managerial labor contracts under two alternative hypotheses incentives in which productivity depends on unobservable effort and learning in which ability is unknown and is revealed over time shared and conflicting implications of these competing models are developed in terms of experienceearnings profiles and the relation between compensation and performance i empirically examine these theoretical results by using a longitudinal sample of 1 488 chief executive officers followed from 1974 1985 the data yield mixed evidence that generally supports the learning hypothesis over the incentive hypothesis

changes in the u s wage structure 1963 1987 application of quantile regression the 1980 s witnessed rapid changes in the structure of wages in the united states in this study recently developed techniques for quantile regression are applied to every march current population survey since 1964 and changes in the return to schooling and experience at different points of the wage distribution are examined the quantile regression technique parsimoniously describes the entire conditional wage distribution this conditional distribution is used to examine changes in within group wage inequality as measured by the difference between conditional quantiles two linear models are considered a simple one group model and a 16 group model the results suggest that the returns to schooling and experience differ across quantiles of the wage distribution but their patterns of change are similar significant differences in wage inequality are also found across the various skill groups the paper also presents a new imputation method for cps data

the creation and capture of rents wages and innovation in a panel of u k companies this paper examines the impact of technological innovation on wages using a panel of british firms a head count measure of major innovations between 1945 and 1983 is combined with share price and accounting information innovating firms are found to have higher average wages but rival innovation tends to depress own wages this appears consistent with a model where wages are partly determined by a sharing in the rents generated by innovation in other words innovation may be a good instrument for proxies for rents such as profitability quasi rents or tobin s average q instrumental variable estimates of the elasticity between wages and quasi rents are about 0 29

climate change and optimal energy technology r d policy public policy response to global climate change presents a classic problem of decision making under uncertainty theoretical work has shown that explicitly accounting for uncertainty and learning in climate change can have a large impact on optimal policy especially technology policy however theory also shows that the specific impacts of uncertainty are ambiguous in this paper we provide a framework that combines economics and decision analysis to implement probabilistic data on energy technology research and development r d policy in response to global climate change we find that given a budget constraint the composition of the optimal r d portfolio is highly diversified and robust to risk in climate damages the overall optimal investment into technical change however does depend in a non monotonic way on the risk in climate damages finally we show that in order to properly value r d abatement must be included as a recourse decision

measuring ecological efficiency with data envelopment analysis dea abstract the measurement of ecological efficiency provides some important information for the companies environmental management ecological efficiency is usually measured by comparing environmental performance indicators data envelopment analysis dea shows a high potential to support such comparisons as no explicit weights are needed to aggregate the indicators in general dea assumes that inputs and outputs are goods but from an ecological perspective also bads have to be considered in the literature bads are treated in different and sometimes arbitrarily chosen ways this article aims at the systematic derivation of ecologically extended dea models starting from the assumptions of dea in production theory and activity analysis a generalisation of basic dea models is derived by incorporating a multi dimensional value function f extended preference structures can be considered by different specifications of f e g specifications for ecologically motivated applications of dea

wage compression within the firm evidence from an indexation scheme we revisit the role of labour market institutions by showing how they affect the sharing of firm specific rents between employers and employees we look at an italian wage indexation mechanism scala mobile that compressed the distribution of wages imposing real wage increases at the bottom of the distribution after developing a simplified version of a search model with intra firm bargaining and on the job search we document that skilled workers received lower wage adjustments when employed at firms with many unskilled workers and they tended to move towards more skill intensive firms moreover the system drove the least skill intensive firms out of the market

managing innovation optimal incentive contracts for delegated r d with double moral hazard abstract managing innovation involves double moral hazard because the principal delegates r d to a specialized agent and then makes decisions to apply the resulting invention double moral hazard is significant because innovation by the principal implies that the optimal incentive contract satisfies monotonicity conditions the analysis shows that the optimal incentive contract for delegated r d is an option delegated r d with simultaneous sampling results in shirking but delegated r d with sequential sampling attains the efficient outcome the analysis considers a combined problem with simultaneous and sequential search and gives sufficient conditions under which delegated r d attains the first best the discussion also considers delegated r d with stochastic innovation and with stochastic quality of inventions

incentives in organizations n 1975 steven kerr published on the folly of rewarding a while hoping for b the argument was simple you get what you pay for kerr distilled this unifying theme from a disparate set of examples involving politicians soldiers doctors orphanage directors professors and students as well as manufacturing and clerical employees and even human resource managers from these examples kerr pp 77980 concluded that two main causes of distorted incentives are fascination with an objective criterion where individuals seek to establish simple quantifiable standards against which to measure and reward performance and overemphasis on highly visible behaviors when some parts of the task are highly visible while others are not it took agency theory 15 years to express kerr s title not to mention to evaluate or extend his conclusions during this period agency theory was obsessed with the tradeoff between incentives and insurance even though clear eyed observations like kerr s about the design and performance of real incentive contracts suggested that several other issues are at least as important fortunately recent work has brought agency theory not only to kerr s position but beyond in this paper i summarize four new strands in agency theory that help me think about incentives in real organizations as a point of departure i begin with a quick sketch of the classic agency model i then discuss static models of objective performance measurement that sharpen kerr s argument repeated game models of subjective performance assessments incentives for skill development rather than simply for effort and incentive contracts between versus within organizations i con

a literature study for dea applied to energy and environment abstract this study systematically summarizes previous research efforts on data envelopment analysis dea applied to energy and environment in the past four decades including concepts and methodologies on dea environmental assessment industrial developments are very important for all nations in terms of their economic prosperities a problem is that the development produces various pollutions on air water and other types of contaminations all of which are usually associated with our health problems and climate changes thus it is necessary for us to consider how to make a balance between economic success and pollution mitigation to maintain a high level of social sustainability in the world it is widely considered that dea is one of the methodologies to examine the level of sustainability this study examines a recent research trend on dea applications from 1980s to 2010s nowadays many researchers have paid serious attention on how to combat various difficulties in the areas of energy and environment as a result the number of articles on dea applications on energy and environment has dramatically increased particularly after 2000s however it is true that dea has strengths and drawbacks in the applications therefore it is very important for us to carefully use dea for guiding large policy issues and business strategies such as the global warming and climate change an underlying premise of this study is that technology innovation in engineering and natural science may solve various problems by linking it with political and managerial efforts the use of dea provides a methodological linkage among them so enhancing the practicality in mitigating problems due to climate change and environmental pollutions this literature study along with a summary on conceptual and methodological developments provides us with guidelines for our future research works on dea on energy and environment issues

the polarization of the u s labor market this paper analyzes a marked change in the evolution of the u s wage structure over the past fifteen years divergent trends in upper tail 90 50 and lower tail 50 10 wage inequality we document that wage inequality in the top half of distribution has displayed an unchecked and rather smooth secular rise for the last 25 years since 1980 wage inequality in the bottom half of the distribution also grew rapidly from 1979 to 1987 but it has ceased growing and for some measures actually narrowed since the late 1980s furthermore we find that occupational employment growth shifted from monotonically increasing in wages education in the 1980s to a pattern of more rapid growth in jobs at the top and bottom relative to the middles of the wage education distribution in the 1990s we characterize these patterns as the u201cpolarization u201d of the u s labor market with employment polarizing into high wage and low wage jobs at the expense of middle wage work we show how a model of computerization in which computers most strongly complement the non routine abstract cognitive tasks of high wage jobs directly substitute for the routine tasks found in many traditional middle wage jobs and may have little direct impact on non routine manual tasks in relatively low wage jobs can help explain the observed polarization of the u s labor market this abstract was borrowed from another version of this item

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

a resource based perspective on corporate environmental performance and profitability drawing on the resource based view of the firm we posited that environmental performance and economic performance are positively linked and that industry growth moderates the relationship with the returns to environmental performance higher in high growth industries we tested these hypotheses with an analysis of 243 finns over two years using independently developed environmental ratings results indicate that it pays to be green and that this relationship strengthens with industry growth we conclude by highlighting the study s academic and managerial implications making special reference to the social issues in management literature

optimal incentive contracts in the presence of career concerns theory and evidence this paper studies optimal incentive contracts when workers have career concerns concerns about the effects of current performance on future compensation we show that the optimal compensation contract optimizes total incentives the combination of the implicit incentives from career concerns and the explicit incentives from the compensation contract thus the explicit incentives from the optimal compensation contract should be strongest for workers close to retirement because career concerns are weakest for these workers we find empirical support for this prediction in the relation between chief executive compensation and stock market performance

bayesian conjoint choice designs for measuring willingness to pay in this paper we propose a new criterion for selecting efficient conjoint choice designs when the interest is in quantifying willingness to pay wtp the new criterion which we call the wtp optimality criterion is based on the c optimality criterion which is often used in the optimal experimental design literature we use a simulation study to evaluate the designs generated using the wtp optimality criterion and discuss the design of a real life conjoint experiment from the literature the results show that the new criterion leads to designs that yield more precise estimates of the wtp than bayesian d optimal conjoint choice designs which are increasingly being seen as the state of the art designs for conjoint choice studies and to a substantial reduction in the occurrence of unrealistically high wtp estimates

if you have the flu symptoms your asymptomatic spouse may better answer the willingness to pay question evidence from a double bounded dichotomous choice model with heterogeneous anchoring the small sample size of contingent valuation cv surveys conducted in patients may have limited the use of the single bounded sb dichotomous choice format which is recommended in environmental economics in this paper we explore two ways to increase the statistical efficiency of the sb format 1 by the inclusion of proxies in addition to patients 2 by the addition of a follow up dichotomous question i e the double bounded db dichotomous choice format we found that patients n 223 and spouses n 64 answering on behalf of the patient had on average a similar willingness to pay for earlier alleviation of flu symptoms however a patient was significantly more likely to anchor his her answer on the first bid as compared to a spouse finally our original db model with shift effect and heterogeneous anchoring reconciled the discrepancies found in willingness to pay statistics between sb and db models in keeping with increased statistical efficiency

the economics of real superstars the market for rock concerts in the material world beginning in 1997 the price of concert tickets took off and ticket sales declined from 1996 to 2003 for example the average concert price increased by 82 while the cpi increased by 17 explanations for price growth include 1 the possible crowding out of the secondary ticket market 2 rising superstar effects 3 baumols and bowen s disease 4 increased concentraion of promoters and 5 the erosion of complementarities between concerts and album sales because of file sharing and cd copying the article tentatively concludes that the decline in complementarities is the main cause of the recent surge in concert prices

a conditional directional distance function approach for measuring regional environmental efficiency evidence from uk regions abstract this paper by using conditional directional distance functions as introduced by simar and vanhems j econometrics 166 2012 342 354 modifies the model by fare and grosskopf eur j operat res 157 2004 242 245 and examines the link between regional environmental efficiency and economic growth the proposed model using conditional directional distance functions incorporates the effect of regional economic growth on regions environmental efficiency levels the results from uk regional data reveal a negative relationship between regions gdp per capita and environmental inefficiency up to a certain gdp per capita level after that level it appears that the relationship becomes positive as an overall result the regional environmental inefficiency gdp per capita relationship appears to have a u shape form

the tenuous trade off between risk and incentives empirical work testing for a negative trade off between risk and incentives has not had much success the data suggest a positive relationship between measures of uncertainty and incentives rather than the posited negative trade off i argue that the existing literature fails to account for an important effect of uncertainty on incentives through the allocation of responsibility to employees when workers operate in certain settings firms are content to assign tasks to workers and monitor their inputs by contrast when the situation is more uncertain they delegate responsibility to workers but to constrain their discretion base compensation on observed output

ecological modernisation new perspectives abstract ecological modernisation understood as systematic eco innovation and its diffusion has by far the largest potential to achieve environmental improvements in general the market logic of modernisation and competition for innovation combined with the market potential of global environmental needs serve as important driving forces behind ecological modernisation in recent times however additional factors like rising energy prices or fears from climate change have favoured the rise of this innovation based approach to environmental policy the article deals with two special driving forces first there is growing evidence for the importance of smart environmental regulation secondly the increasingly complex actor constellation of global environmental governance leads to mounting business risks for polluters and thereby exerts pressure for eco innovation despite these favourable framework conditions the strategy of ecological modernisation nonetheless faces a number of inherent limitations these include the unavailability of marketable technological solutions for relevant environmental problems like the loss of species the rebound effect neutralising the incremental environmental improvements through economic growth the dilemma of the n curve as well as resistance by modernisation losers against this background structural solutions seem indispensable here eco innovations should be supported by transition management or ecological structural policy

why are researchers paid bonuses on technology spillovers and market rivalry abstract a temporary change in pay to employed inventors around the time of patent application has been documented a theoretical model is here developed to provide an explanation to said findings based on the idea that inventors may be able to use the knowledge previously generated while working in a firm in a rival company the model features firms who hire workers in r d functions to make product innovations the innovation process consists of distinct phases each with different access to information about the innovation value for firms firms compete to attract workers and workers can transfer part of the generated new knowledge to a new employer results suggest that the capital intensity of r d investments and the type and size of knowledge spillovers may affect the probability to observe bonus pay at the time of a patent application different tax incentives and subsidies are then studied as a means to correct for possible under investment of capital we study the effect of a patent box a subsidy to r d capital investments and a subsidy to bonus pay when market rivalry prevails over positive knowledge externalities a bonus pay incentive was found to obtain the social first best while a patent box or a subsidy to capital investment would cause overinvestment when positive knowledge externalities prevail either a patent box or a subsidy to capital investment obtain the social optimal level of capital investments

are ceos really paid like bureaucrats a common view is that there is little correlation between firm performance and ceo pay using a new fifteen year panel data set of ceos in the largest publicly traded u s companies we document a strong relationship between firm performance and ceo compensation this relationship is generated almost entirely by changes in the value of ceo holdings of stock and stock options in addition we show that both the level of ceo compensation and the sensitivity of compensation to firm performance have risen dramatically since 1980 largely because of increases in stock option grants

internal capital markets and firm level compensation incentives for division managers do multidivisional firms structure compensation contracts for division managers to mitigate incentive problems in their internal capital markets i find evidence that compensation and investment incentives are substitutes firms providing a stronger link to firm performance in incentive compensation for division managers also provide weaker investment incentives through the capital budgeting process specifically as the proportion of incentive pay for division managers that is based on firm performance increases division investment is less responsive to division profitability these findings are generally consistent with a model of influence activities by division managers in interdivisional capital allocation decisions

career concerns of mutual fund managers we examine the labor market for mutual fund managers using data from 1992 1994 we find that termination is more performance sensitive for younger managers we identify possible implicit incentives created by the termination performance relationship the shape of the termination performance relationship may give younger managers an incentive to avoid unsystematic risk direct effects of portfolio composition may also give younger managers an incentive to herd into popular sectors consistent with these incentives we find that younger managers hold less unsystematic risk and have more conventional portfolios promotion incentives and market responses to managerial turnover are also studied

sustainability performance for brazilian electricity power industry an assessment integrating social economic and environmental issues the increased pressure on companies to address sustainability issues has resulted in the development of several voluntary corporate sustainability integration approaches the array of existing approaches is large and overwhelming resulting in companies not understanding what corporate sustainability really means for their businesses considering environmental economic and social issues this paper aims at assessing the performance of the brazilian electricity power industry in terms of its sustainability performance an analysis of global reporting initiative gri indicators for the energy sector lead to an assessment of its sustainability performance by applying data envelopment analysis dea specified with a directional distance function ddf five scenarios were created i flexible weights ii triple bottom line iii social issues iv economic issues and v environmental issues with considering i flexibility weights almost all companies are efficient we also found a significant difference when we compared i with the other four scenarios ii iii iv and v taking into account the triple bottom line scenario ii the results indicate that companies were less efficient when compared with the flexible weights scenario i taking into account the last three scenarios iii iv and v only four companies were considered as providing top benchmarks in sustainability performance

multi output efficiency with good and bad outputs abstract cherchye de rock dierynck roodhooft and sabbe 2013 introduced a dea methodology that is specially tailored for multi output efficiency measurement the methodology accounts for jointly used inputs and incorporates information on how inputs are allocated to outputs in this paper we present extensions that render the methodology useful to deal with undesirable or bad outputs in addition to desirable or good outputs interestingly these extensions deal in a natural way with several limitations of existing dea approaches to treat undesirable outputs we also demonstrate the practical usefulness of our methodological extensions through an application to us electric utilities

optimal designs of discrete response experiments in contingent valuation studies optimal designs for estimating model parameters and other characteristics such as mean and median willingness to pay are discussed when a logistic or a probit regression model is used for analyzing a contingent valuation study with discrete questions a numerical example related to a study of the value of preserving some virgin forests in sweden illustrates the efficiencies of different designs and how a sequential procedure can be applied copyright 1992 by mit press

consequences of using different question formats in contingent valuation a monte carlo study monte carlo experiments were conducted to compare regression parameter and willingness to pay wtp estimates using the contingent valuation method s referendum and payment card questioning formats strategic bias was controlled by making responses consistent with the true wtp two wtp models were constructed linear and log linear in explanatory variables based on the efficiency and mean squared error criteria the payment card model was superior to the referendum model however neither model outdid the other when the unbiasedness criterion was used the performance of either model depends on the choice and distribution of the bids and payment card categories

the direct incidence of corporate income tax on wages a stylised model is provided to show how the direct effect of corporate income tax on wages can be identified in a bargaining framework using cross company variation in tax liabilities conditional on value added per employee using data on 55 082 companies located in nine european countries over the period 1996 2003 we estimate the long run elasticity of the wage bill with respect to taxation to be 0 093 evaluated at the mean this implies that an exogenous rise of 1 in tax would reduce the wage bill by 49 cents only a weak evidence of a difference for multinational companies is found

comparative advantage relative wages and the accumulation of human capital i apply ricardo s principle of comparative advantage to a theory of factor substitutability in a model with a continuum of worker and job types highly skilled workers have a comparative advantage in complex jobs the model satisfies the distance dependent elasticity of substitution dides characteristic substitutability between types declines with their skill distance i analyze changes in relative wages due to human capital accumulation the concept of a complexity dispersion parameter or compression elasticity is introduced empirical studies suggest its value to be equal to two a 1 percent increase in the stock of human capital reduces the mincerian return by 2 percent

individual preferences organization and competition in a model of r d incentive provision abstract understanding the organization of rd 2 knowledge is not perfectly appropriable 3 scientists are responsive to both monetary and non monetary incentives and 4 firms compete on the product market we show that both knowledge spillovers and market competition affect the incentives given to scientists and these effects interact first high knowledge spillovers lead firms to soften incentives when product market competition is high and to strengthen incentives when competition is low second the relationship between the intensity of competition and the power of incentives is u shaped with the exact shape depending on the degree of knowledge spillovers we also show that the performance contingent pay for both applied and basic research increases with the non pecuniary benefits that scientists obtain from research while the fixed component decreases we relate our findings to the existing empirical evidence and also discuss their implications for management and public policy

the dependence of pay performance sensitivity on the size of the firm i analyze the relationship between firm size and the extent to which executive compensation depends on the wealth of the firm s shareholders i use a simple agency model to motivate an econometric model of this relationship estimating this model on chief executive officer ceo compensation data using nonlinear least squares i determine that pay performance sensitivity as defined by jensen and murphy 1990b appears to be approximately inversely proportional to the square root of firm size however measured i also analyze the properties of pay performance sensitivity for teams of executives working for the same firm and show it to have similar properties as ceo pay performance sensitivity

pesticide use environmental spillovers and efficiency a dea risk adjusted efficiency approach applied to dutch arable farming pesticides are widely used by crop producers in developed countries to combat risk associated with pests and diseases however their indiscriminate use can lead to various environmental spillovers that may alter the agricultural production environment thus contributing to production risk this study utilises a data envelopment analysis dea approach to measure performance of arable farms incorporating pesticides environmental spillovers and output variance as undesirable outputs in the efficiency analysis and taking explicitly into account the effect of pesticides and other inputs on production risk the application focuses on panel data from dutch arable farms over the period 2003 2007 a moment approach is used to compute output variance providing empirical representations of the risk increasing or decreasing nature of the used inputs finally shadow values of risk adjusted inputs are computed we find that pesticides are overused in dutch arable farming and there is a considerable evidence of the need for decreasing pesticides environmental spillovers

the political economy of technological innovation and employment building on the varieties of capitalism thesis of comparative advantages in technological innovation the authors theorize the effect of sociopolitical coordination from a dynamic perspective and then apply the dynamic theories to the political economy of employment in comparison to the existing employment literature situated in a constant technology context based on cross sectional survey as well as pooled time series aggregate data the authors argue that new technologies not only increase productivity through process innovation but also generate rents through product innovation by preventing opportunistic behavior between firms sociopolitical coordination intensifies reciprocal sharing of innovation which increases productivity returns but dilutes rents leading to comparative advantage in process over product innovation because process innovation is labor saving but product innovation is employment friendly interfirm coordination further leads to comparative disadvantage in job creation from in

bargaining sorting and the gender wage gap quantifying the impact of firms on the relative pay of women there is growing evidence that rm specic pay premiums are an important source of wage inequality these premiums will contribute to the gender wage gap if women are less likely to work at high paying rms or if women negotiate worse wage bargains with their employers than men using longitudinal data on the hourly wages of portuguese workers matched with balance sheet information for rms we show that the wages of both men and women contain rm specic premiums that are strongly correlated with employer productivity we then show how the impact of these rm specic pay dierentials on the gender wage gap can be decomposed into a combination of bargaining and sorting eects consistent with the bargaining literature we nd that women receive only 90 of the rm specic pay premiums earned by men notably we obtain very similar estimates of the relative bargaining power ratio from our analysis of between rm wage premiums and from analyzing changes in

ceo incentives and firm size we develop a model that clarifies how to measure ceo incentive strength and how to reconcile the enormous differences in pay sensitivities between executives in large and small firms the crucial parameter is shown to be the elasticity of ceo productivity with respect to firm size we find that ceo marginal products rise significantly with firm size confirming rosen s conjecture that ceos of large firms have a chain letter effect on firm performance and overall ceo incentives are roughly constant or decline slightly with firm size we employ a multitask model to discuss implications for the design of control systems

eco efficiency analysis of power plants an extension of data envelopment analysis abstract in public discussion on environmental policy the notion of eco efficiency is often used the joint production of goods and undesirable outputs such as pollutants which may not be freely disposable without costs causes difficulties to measure the overall performance of the firm because of the absence of market prices for the undesirable outputs we are not able to estimate the environmental costs some of the measurement and evaluation difficulties can be overcome by employing data envelopment analysis dea as the efficiency measurement vehicle we propose the use of two different approaches in the first approach we start by decomposing the problem into two parts 1 the problem of measuring technical efficiency as the relation of the desirable outputs to the inputs and 2 the problem of measuring so called ecological efficiency as the relation of the desirable outputs to the undesirable outputs separately those two efficiency indicators are then combined in the second approach we treat pollutants as the inputs in the sense that we wish to increase desirable outputs and decrease pollutants and inputs the approaches are applied to the problem of measuring the efficiency of 24 power plants in a european country

open shop unions and product market competition in this paper we analyse the impact of changes in product market competition on wage outcomes in the presence of an open shop union with less than full union membership product market competition is shown to aect not only a unionised rm s pro ts but also its payoin the event of a dispute in contrast to the pre diction of the standard model increases in product market competition may now increase wage levels the model is therefore able to accommodate the mixed empir ical ndings regarding the impact of product market competition on union wages
