why you can t find a taxi in the rain and other labor supply lessons from cab drivers i replicate and extend the seminal work of camerer et al labor supply of new york city cabdrivers one day at a time quarterly journal of economics 112 1997 407 441 who find that the wage elasticity of daily hours of work for new york city taxi drivers is negative and conclude that their labor supply behavior is consistent with reference dependence in contrast my analysis of the complete record of all trips taken in nyc taxi cabs from 2009 to 2013 shows that drivers tend to respond positively to unanticipated as well as anticipated increases in earnings opportunities additionally using a discrete choice stopping model the probability of a shift ending is strongly positively related to hours worked but at best weakly related to income earned i find substantial heterogeneity across drivers in their elasticities but the estimated elasticities are generally positive and rarely substantially negative i find that new drivers with smaller elasticities are more likely to exit the industry whereas drivers who remain quickly learn to be better optimizers have positive labor supply elasticities that grow with experience these results are consistent with the neoclassical optimizing model of labor supply and suggest that consideration of gain loss utility and income reference dependence is not an important factor in the daily labor supply decisions of taxi drivers jel codes d01 d03 j22

individual heterogeneity and cultural attitudes in credence goods provision abstract i study the heterogeneity of credence goods provision in taxi drivers taking detours in new york city first i document that there is significant detouring on average by drivers second there is significant heterogeneity in detouring across individuals yet each individual s propensity to take detours is stable drivers who detour almost always detour while those who do not detour almost never do drivers who take longer detours on each trip also take such trips more often third cultural attitudes plausibly explain some of this heterogeneity in behavior across individuals

an experimental examination of labor supply and work intensities estimated negative substitution effects on work hours question the empirical validity of the classical labor supply model estimates are reconciled by allowing a dual choice of hours and effort for piecerate workers in such a model these negative substitution effects result from substituting on and off the job leisure we test our model using controlled experimentation on human subjects these experiments while not naturally occurring environments represent real economic choices and can generate data unavailable elsewhere e g effort data the results support our model and they have implications both for labor management and for empirical research focusing only on the hours choice the classical static model of the labor leisure choice offers positive compensated wage effects on hours of work as its main testable implication previous attempts to test this hypothesis with field data have cast doubt on the empirical validity of the static labor supply model due to the frequency of negative estimated compensated wage elasticities a limitation of the model is that it views the choice of hours of work as the only

is tiger woods loss averse persistent bias in the face of experience competition and high stakes although experimental studies have documented systematic decision errors many leading scholars believe that experience competition and large stakes will reliably extinguish biases we test for the presence of a fundamental bias loss aversion in a high stakes context professional golfers performance on the pga tour golf provides a natural setting to test for loss aversion because golfers are rewarded for the total number of strokes they take during a tournament yet each individual hole has a salient reference point par we analyze over 2 5 million putts using precise laser measurements and find evidence that even the best golfers including tiger woods show evidence of loss aversion jel d03 d81 l83

when to quit narrow bracketing and reference dependence in taxi drivers abstract taxi drivers provide an ideal setting for testing various models of labor supply despite this the literature studying driver behavior has produced mixed evidence of which labor supply model best applies to driver labor supply using a novel analysis and large datasets of taxi trips from two different cities this paper provides a unifying analysis which reconciles previous inconsistencies in evidence for reference dependence in taxi drivers by testing for a particular non linear relationship between shift income and drivers hazard of stopping i identify behavior that is consistent with prospect theoretic s shaped reference dependence as opposed to the more extensively examined loss aversion model of reference dependence this particular model of reference dependence in this setting allows me to estimate individual driver reference points without an explicit functional form or ex ante assumptions about the existence of a reference point

reference dependent preferences and labor supply the case of new york city taxi drivers i develop a model of daily labor supply where preferences are dependent on a reference daily income level and i apply this model to data on the labor supply of new york city taxi drivers i find that there may be a reference level of income on a given day that affects labor supply however there is substantial day to day variation in a given driver s reference level and most shifts end before reaching the reference income level this pattern is inconsistent with an important role for reference dependent preferences

do renewable energy technology innovations promote china s green productivity growth fresh evidence from partially linear functional coefficient models abstract renewable energy technology innovation can benefit the environment by promoting green productivity as proposed by existing theoretical studies however recent uneven developments of both environmental performance and renewable energy technology among regions in china remind us to revisit the above theoretical link in this paper we relax the hypothesized homogeneity and linearity in traditional empirical models to investigate the effects of renewable energy technology innovation on china s green productivity the results of the partially linear functional coefficient models show that the effect of renewable energy technological innovation on green productivity is significant only when the relative income level of a province passes a critical turning point beyond the turning point such an effect increases with the growth of relative income levels finally we provide provincial specific policy implications based on the estimated nonparametric relationship between renewable energy technology innovation and green productivity

a shred of credible evidence on the long run elasticity of labor supply all public policies regarding taxation and the redistribution of income rely on assumptions about the long run effect of wages rates on labour supply the variation in existing estimates calls for a simple natural experiment in which men can change their hours of work and in which wages have been exogenously and permanently changed we use a panel dataset of taxi drivers who choose their own hours and who experienced two exogenous permanent fare increases and estimate an elasticity of labour supply of 0 2 implying that income effects dominate substitution effects in the long run labour supply of males

does market experience eliminate market anomalies the case of exogenous market experience a vibrant literature has emerged that suggests willingness to pay and willingness to accept measures of value are quite different for inexperienced consumers but that value differences erode with market experience one potential shortcoming of this literature is that market experience is endogenous this study presents a framed field experiment that exogenously induces market experience empirical findings support the premise that market experience alone can eliminate an important market anomaly

the effect of wage subsidies on piece rate workers evidence from the penny per pound program in florida abstract this paper studies a fair trade program in which consumers provide a wage subsidy bonus to piece rate tomato pickers the total subsidy determined by sales to participating buyers is divided among workers based on their relative output a worker who produces more gets a larger share of the bonus although seemingly mimicking the existing piece rate pay scheme the mechanism associated with the bonus payment is really a relative performance evaluation as the size of total bonus is exogenous and invariant to workers effort therefore for a given sized subsidy the combined total or per worker average utility gains would become the largest if the workers keep their efforts at the pre program level empirical analysis shows that worker effort and hence productivity increases substantially in response to the program suggesting that currently workers combined gains per dollar of subsidy are not being maximized

an empirical analysis of the daily labor supply of stadium venors this paper analyzes the daily labor supply behavior of food and beverage vendors at a single stadium over an entire baseball season this labor market is attractive for the study of labor supply both because ofvendors unilateraly decide whether to participate on each game date and because canges in product demand conditions across days are large and highly predictable generating exogenous game to game variation in the vendor wage i exploit the observable shift in product demand conditions across games to esumate the labor supply participation elasticity of stadium vendors estimates that recognize that demand conditions and vendor labor supply decisions simultancously determine the venofdor wage always find substantial labor supply elasticities typically in the 55 65 range in contract estimates that ignore the endoreneity of the ties these results highlight the imporatance of using demand shift markets

how many pears would a pear packer pack if a pear packer could pack pears at quasi exogenously varying piece rates abstract we examine labor supply using a unique dataset collected from a large pear packing factory pear packers face both expected and unexpected shocks to their wages and we use this to evaluate different models of inter temporal labor supply we find strong evidence for reference dependent preferences but only mixed support for models of rational expectations based targets

wage elasticities in working and volunteering the role of reference points in a laboratory study we experimentally test how effort responds to wages randomly assigned to accrue to individuals or to a charity in the presence of expectations based reference points or targets when individuals earn money for themselves higher wages lead to higher effort with relatively muted targeting behavior when individuals earn money for a charity higher wages instead lead to lower effort with substantial targeting behavior a reference dependent theoretical framework suggests an explanation for this differential impact when individuals place less value on earnings such as when accruing earnings for a charity instead of themselves more targeting behavior and a more sluggish response to incentives should result results from an additional experiment add support to this explanation when individuals select into earning money for a charity and thus likely place a higher value on those earnings targeting behavior is muted and no longer generates a negative effort response to higher wages data and the online appe

risk and precautionary saving in two person households the existing literature on precautionary saving is based almost entirely on the assumption that the household acts as if it consisted of a single individual decision taker in reality saving decisions are typically taken by two person households this paper examines the implications of this observation for the existence of precautionary saving and shows that the assumption that the individual utility functions satisfy the conditions for precautionary saving to exist can imply that the household exhibits precautionary saving but only under strong assumptions on the type of risk change being considered

the response of worker effort to piece rates we measure the elasticity of worker effort with respect to changes in the piece rate using panel data collected from the payroll records of a british columbia tree planting firm our data contain information on daily worker productivity and the piece rate received over a five month period using a structural model to control for the endogeneity of the piece rate we estimate this elasticity to be approximately 2 14 we also calculate a nonstructural lower bound to this elasticity equal to 0 77 structural estimation also allows us to perform policy experiments and to compare firm profits under alternative compensation systems our results suggest that profits would increase by at least 17 percent were the firm to implement the optimal static contract as predicted by principal agent theory this increase in profits would be due to capturing worker rents after the revelation of private information over ability yet only a negligible proportion of these rents could be captured while inducing workers to reveal ability truthfully suggesting that dynamic considerations were important in determining the firm s actual choice of contract

evaluating impact effects of tax reforms abstract this survey paper provides coverage of the inputs from the theory side which go into the empirical analysis of impact effects of tax reforms inequality social welfare progressivity and horizontal inequity effects are considered the value judgements inherent in selecting the target group for analysis specifying welfare through household utility equivalizing incomes and otherwise incorporating differences in household needs into utilitarian analysis are all explained the evaluation procedures described include dominance checks and index comparisons the inequality and social welfare tests are also applicable to other comparisons of income distribution standard computer software to sort cumulate and compute covariances is all that is required to undertake the necessary computations using microdata

a decade s debate on the nexus between corporate social and corporate financial performance a critical review of empirical studies 2002 2011 abstract theoretical discussions and empirical studies on the nexus between corporate social responsibility corporate social performance and corporate financial performance have never ceased since the origin of the concepts the development trajectories of such studies should be articulated with a view to informing practical corporate social responsibility applications and theoretical studies in the future this paper presents a critical review of relevant empirical research articles on the nexus between corporate social performance and corporate financial performance published during the ten year period from 2002 to 2011 using mixed methods of content analyses and statistical analyses the paper reviews 84 empirical studies of this kind published during the period the results indicate that despite the enormous amount of previous studies the corporate social performance and corporate financial performance nexus is a line of inquiry that remains inconclusive the pattern of corporate social performance corporate financial performance relationship research in the decade examined has shifted towards exploring the linkages between specific aspects of the two constructs the positive relationships between these specific aspects in dual directions are confirmed by most of the studies examined in this paper the paper also examines the impact of time and space change on the corporate social performance corporate financial performance nexus the findings show that researchers have gradually recognized that the relationship is not static but changes over time furthermore the paper finds that corporate social responsibility has been increasingly debated in developing countries and in specified industrial settings the review concludes that to explore the corporate social performance corporate financial performance nexus by contextualizing it in a specified community and or examine its dynamics is a promising research area that can yield significant academic and practical values

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

the normative significance of using third degree stochastic dominance in comparing income distributions abstract third degree stochastic dominance tsd has been promoted as a normative criterion to refine the partial ordering over income distributions induced by second degree stochastic dominance i e the lorenz criterion this paper enhances our understanding of the normative properties of tsd by defining a rawlsian composite transfer to be a progressive transfer combined with a regressive transfer with the former taking place in a lower income region we show how tsd is a rawlsian extension of the lorenz criterion we also show how this property is affected by changes in the original vector of incomes journal of economic literature classification number d63

disruptive change in the taxi business the case of uber in most cities the taxi industry is highly regulated and utilizes technology developed in the 1940s ride sharing services such as uber and lyft which use modern internet based mobile technology to connect passengers and drivers have begun to compete with traditional taxis this paper examines the efficiency of ride sharing services vis a vis taxis by comparing the capacity utilization rate of uberx drivers with that of traditional taxi drivers in five cities the capacity utilization rate is measured by the fraction of time a driver has a fare paying passenger in the car while he or she is working and by the share of total miles that drivers log in which a passenger is in their car the main conclusion is that in most cities with data available uberx drivers spend a significantly higher fraction of their time and drive a substantially higher share of miles with a passenger in their car than do taxi drivers four factors likely contribute to the higher capacity utilization rate of uberx drivers 1 uber s more efficient driver passenger matching technology 2 the larger scale of uber than taxi companies 3 inefficient taxi regulations and 4 uber s flexible labor supply model and surge pricing more closely match supply with demand throughout the day

economic growth and energy consumption causal nexus viewed through a bootstrap rolling window one puzzling results in the literature on energy consumption economic growth causality is the variability of results particularly across sample periods sample sizes and model specification in order overcome these issues this paper analyzes the causal links between energy consumption and economic growth for g 7 countries using bootstrap granger non causality tests with fixed size rolling subsamples the data used includes annual total energy consumption and real gross domestic product gdp series from 1960 to 2006 for g 7 countries excluding germany for which the sample period starts from 1971 using the full sample bootstrap granger causality test we find that there is predictive power from energy consumption to economic growth only for canada however parameter instability tests show that none of the estimated models have constant parameters and hence the full sample results are not reliable analogous to the full sample results the results obtained from the bootstrap rolling window estimation indicate no consistent causal links between energy consumption and economic growth we however find that causal links are present between the series in various subsamples furthermore these subsample periods correspond to significant economic events indicating that the findings are not statistical artefacts but correspond to real economic changes our results encompass previous findings and offer an explanation to varying findings

single crossing conditions in comparisons of tax progressivity statements to the effect that one tax is more progressive than another are frequently made but seldom explained starting from a criterion of lorenz domination this paper shows how an intuitively appealing single crossing condition on appropriately normalized tax schedules may be used in progressivity comparisons this condition is closely related to and illuminates the necessary and sufficient condition derived by jakobsson 1976 for the distributional implications of alternative taxes to be inferred from their schedules alone

returns to scale market power and the nature of price rigidity in new keynesian models with self fulfilling expectations increasing returns to scale and firms market power are two potential sources of sunspot expectations in neoclassical models we show that in new keynesian models returns to scale and market power can have fundamentally different implications for broad macroeconomic issues including self fulfilling expectations depending on the nature of price rigidity our findings suggest that the design of stabilization monetary policy can depend on precise knowledge about the economy s real and nominal features therefore a clear understanding of the specific economic environment and its relevance to monetary policymaking for ensuring macroeconomic stability can be an integrated part of monetary policy practice

peers at work we study peer effects in the workplace specifically we investigate whether how and why the productivity of a worker depends on the productivity of coworkers in the same team using high frequency data on worker productivity from a large supermarket chain we find strong evidence of positive productiv ity spillovers from the introduction of highly productive personnel into a shift worker effort is positively related to the productivity of workers who see him but not workers who do not see him additionally workers respond more to the presence of coworkers with whom they frequently interact we conclude that social pressure can partially internalize free riding externalities that are built into many workplaces jel j24 l81 m54

what accounts for the growth of carbon dioxide emissions in advanced and emerging economies the role of consumption technology and global supply chain participation abstract this paper examines the driving forces behind the growth in carbon dioxide emissions in forty advanced and emerging economies between 1995 and 2008 we use the global supply chain concept introduced in timmer et al 2014 to measure co2 emissions in internationally fragmented production networks and embed the concept in structural decomposition analysis our findings suggest that rising levels of domestic consumption are related to increased carbon dioxide emissions in both advanced and emerging economies a substantial share of co2 emissions growth in emerging economies is accounted for by increased participation in global supply chains however even for countries that rapidly integrated in global production networks such as china rising domestic consumption accounts for the majority of territorial emissions

productivity in piece rate labor markets evidence from rural malawi abstract piece rate compensation is a common feature of developing country labor markets but little is known about how piece rate workers respond to incentives or the tradeoffs that an employer faces when setting the terms of the contract in a field experiment in rural malawi we hired casual day laborers at piece rates and collected detailed data on the quantity and quality of their output specifically we use a simplified becker degroot marschak mechanism which provides random variation in piece rates conditional on revealed reservation rates to separately identify the effects of worker selection and incentives on output we find a positive relationship between output quantity and the piece rate and show that this is solely the result of the incentive effect not selection in addition we randomized whether workers were subject to stringent quality monitoring monitoring led to higher quality output at some cost to the quantity produced however workers do not demand higher compensation when monitored and monitoring has no measurable effect on the quality of workers willing to work under a given piece rate together the set of worker responses that we document lead the employer to prefer a contract that offers little surplus to the worker consistent with an equilibrium in which workers have little bargaining power

how population and energy price affect china s environmental pollution abstract this paper examines the impact of population and energy price on china s environmental pollution through both industrial and residential channels our theoretical models reveal that the influences of population on environmental pollution are contingent on wage stickiness and wage elasticity we also predict that environment pollution decreases with rising energy price but downward energy price distortion intensifies environmental pollution we test these hypotheses using panel data of 30 chinese provinces from 2001 to 2016 and employing both constant coefficient and time varying coefficient panel data models to conduct analyses our empirical results show that population growth increased urbanization and energy price distortion all intensify environmental pollution while population aging and rising energy price tend to alleviate environmental pollution our results also reveal significant regional and time heterogeneity on the impact of population factors and energy price on china s environmental pollution

inequality reducing properties of composite taxation abstract on the one hand we know that the more progressive a tax schedule the more equally distributed the after tax incomes u jakobsson j public econ 5 1976 161 168 on the other hand most tax systems involve a complex procedure where individual incomes are successively subjected to different rounds of taxation we study in the paper the inequality reducing properties of the composition of different taxation schemes and we identify necessary and sufficient conditions for after tax inequality to decrease when the degree of progressivity of one element or more of the tax system is increased for the sake of generality we assimilate the set of income distributions with the space of probability measures over an interval of the real line and any function that associates after tax incomes to before tax incomes is viewed as a taxation scheme this general approach proves to be particularly powerful when investigating the restrictions the egalitarian principle imposes on the set of admissible taxation schemes journal of economic literature classification numbers d31 d63 h24

energy innovations ghg emissions nexus fresh empirical evidence from oecd countries abstract this study explores the impact of improvements in energy research development erd on greenhouse gas ghg emissions using environmental kuznets curve hypothesis for 28 oecd countries over the period of 1990 2014 in doing so we have employed a panel data where public budget in energy research development and demonstration erd d has transformed into a finite inverted v lag distribution model developed by de leeuw 1962 this model considers that energy innovation accumulates in time and presents empirical evidence how energy innovation contributes in reducing energy intensity and environmental pollution as well our results indicate that energy innovation measures require lapses of time to reach their full effect i e innovation applied to measures for environmental correction does not reach its whole effect immediately requiring instead a certain amount of time to pass innovation policies have recommended for improving environmental quality

flat rate taxes and inequality measurement abstract tax flattening exercises which include an increase in personal allowances have been pervasive over the past two decades such changes which typically benefit both the poor and the rich at the expense of the middle class have complex redistributive effects which are not obviously equalizing or disequalizing we develop a systematic approach to comparing the relative inequality of flat rate tax schemes to conventional graduated rate taxes we provide an illustrative example using 1993 u s taxfiler data

exchange rate fluctuations and immigrants labour market outcomes new evidence from australian household panel data abstract in this paper we exploit plausibly exogenous changes in exchange rates across home countries over time and panel data to identify the causal impact of exchange rate fluctuations on australian immigrants labour market outcomes we present new and robust evidence that unlike immigrants in the us those in australia as a whole do not reduce their yearly labour market outcomes when the local currency appreciates while female immigrants don t adjust their labour activities male immigrants reduce their weekly labour supply and hence earn less when the australian dollar appreciates this work also highlights the importance of controlling for individual heterogeneity as well as gender when modelling the labour market behaviour of immigrants

flat income taxation redistribution and labour market performance a flat tax rate on labour income has gained popularity in european countries this article assesses the attractiveness of such a flat tax in achieving redistributive objectives with the smallest distortions to employment we do so by using a detailed applied general equilibrium model for the netherlands the model is empirically grounded in the data and encompasses decisions on hours worked labour force participation skill formation wage bargaining between unions and firms and a wide variety of institutional details the simulations suggest that the replacement of the current tax system in the netherlands by a flat rate will harm labour market performance if aggregate income inequality is contained only flat tax reforms that reduce redistribution will raise employment this finding bolsters the notions from optimal tax literature regarding the equity efficiency trade off and the superiority of nonlinear taxes to obtain redistributive goals in an efficient way

accounting for quality issues with modeling the impact of r d on economic growth and carbon emissions in developing economies the literature on climate policy modeling has paid scant attention to the important role that r d is already playing in industrializing countries such as china where r d investments are targeting not only productivity improvements but also enhancements in the quality and variety of products we focus here on the effects of quality enhancing innovation on energy use and ghg emissions in developing countries we construct an analytical model to show that efficiency improving and quality enhancing r d have opposing influences on energy and emission intensities with the efficiency improving r d having an attenuating effect and quality enhancing r d having an amplifying effect we find that the balance of these opposing forces depends on the elasticity of upstream output with respect to efficiency improving r d the elasticity of downstream output with respect to upstream quality enhancing r d occurring upstream and the relative shares of emissions intensive inputs in the costs of production of upstream versus downstream industries we employ a computable general equilibrium cge simulation of the chinese economy to illustrate the difficulties that arise in incorporating these results into models for climate policy analysis and we offer a simple remedy

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

foreign direct investment co2 emissions nexus in middle east and north african countries importance of biomass energy consumption abstract this study examines the association between foreign direct investment fdi and carbon emissions for the middle east and north african mena region in 1990 2015 including biomass energy consumption as an additional determinant of carbon emissions we apply the generalized method of moments gmm to validate the existence of the pollution haven hypothesis phh the n shaped association is also validated between fdi and carbon emissions the link between economic growth and carbon emissions is inverted u and n shaped that is it satisfies the environmental kuznets curve ekc hypotheses biomass energy use lowers carbon emissions and the causality analysis reveals that fdi causes co2 emissions clearly the results confirm the existence of a feedback effect between economic growth and carbon emissions the connection between biomass energy use and co2 emissions is also bidirectional the empirical findings suggest policy makers to design comprehensive trade and energy policies by targeting the cleaner production practices for not only to ensure environmental sustainability but also to fulfil the objectives of sustainable development goals

the labor supply of fixed wage workers estimates from a real effort experiment abstract fixed wage workers comprise the bulk of the labor force and yet little is known about how they respond to changes in their wage given recent interest in theories of reciprocity and intrinsic motivation and their implications for effort provision the neoclassical prediction seems less obvious today to better understand the motivation of these workers i estimate their labor supply using a real effort experiment two results stand out first no one theory seems to fit the pooled data on average people work considerably harder than the minimum but they do not respond to changes in the wage second pooling the data is deceptive because there seem to be distinct types with differing responses to the wage most workers can be classified as reciprocal or intrinsically motivated and indeed these types respond as theory would predict reciprocators return wage gifts with increased effort and extrinsic incentives crowd out motivation for intrinsic workers

the effect of environmental information disclosure on environmental quality evidence from chinese cities abstract this paper attempts to provide a more systematic view of the relationship between environmental information disclosure eid and environmental consequences to reconcile the existing conceptual controversy and empirical inconclusiveness hence using a panel data of 113 major chinese key environmental protection cities from 2008 to 2018 this study adopts the estimations of dynamic generalized method of moments gmm quantile regression panel threshold model and dynamic spatial durbin model sdm to investigate the effect of eid on environmental quality the non spatial empirical results indicate that eid exerts a positive influence on environmental quality in a particular region and there is a double threshold for the impact of eid this impact becomes pronounced and then strengthened when the level of economic development reaches critical threshold values moreover the first order lag effect of environmental quality and spatial autocorrelation are needed to be incorporated in terms of spatial econometric estimation the results show a positive direct while negative indirect relationship between eid and environmental quality making the total effect nearly zero these findings are evidenced in both the short term contemporaneous and long term cumulative span which reveals so called beggar thy neighbor as well as a zero sum game among local governments overall this study highlights the crucial role of eid in affecting environmental quality and calls for a mutually beneficial coordination between regions

salaries and piece rates compensation can take many forms remuneration can come as pecuniary payments as fringes such as health and pension benefits or as a nonpecuniary reward such as plush office furniture that costs the firm less than it benefits the worker a significant literature has examined the trade offs between pecuniary and nonpecuniary compensation the modern work having been pioneered by rosen 1974 more recently another body of literature has examined the selection of method of total compensation ignoring the distinction between pecuniary and nonpecuniary payment this work has focused on risk and incentive factors it has resulted in comparisons of compensation based on absolute output levels to that based on relative performance it has also led to explorations of the relation of compensation to experience over the work life 2 little attention has been paid to what may be among the most important and obvious distinction in methods of compensation namely the choice between a fixed salary for some period of time that is paying on the basis of input and some workers receive compensation that is specified in advance and not directly contingent on performance instead it depends on an input measure such as hours worked for others compensation is directly related to output this essay is an attempt to predict a firm s choice of compensation method piece rates are defined more rigorously among the more important factors discussed are worker heterogeneity incentives sorting considerations monitoring costs and asymmetric information one result is that salary workers tend to be of lower quality and more homogeneous than are their piece rate counterparts numerous additional results are provided helpful comments by victoria lazear and yoram weiss are gratefully acknowledged support was provided by the department of labor and the national science foundation 1 see lazear and rosen 1981 stiglitz 1981 holmstrom 1982 green and stokey 1983 2 see lazear 1979 1981 and harris and holmstrom in press

the alaskan labor market during the pipeline era built between 1974 and 1977 the trans alaska pipeline was the largest privately financed construction project in world history the alaskan labor market during the pipeline era provides an ideal opportunity to view labor market responses to a large anticipated and temporary shock to labor demand the paper presents several theoretical models of market responses to temporary demand shocks and then assesses the ability of each model to explain the alaskan data among the findings are that alaskan wages were very flexible labor supply was quite elastic on both the intensive hours per worker and extensive number of workers margins and even a major short run demand shock need not have a long run impact

new york city cab drivers labor supply revisited reference dependent preferences with rational expectations targets for hours and income this paper reconsiders whether cabdrivers labor supply decisions reflect reference dependent preferences following botond koszegi and matthew rabin 2006 we construct a model with targets for hours as well as income both determined by rational expectations estimating using henry s farber s 2005 2008 data we show that the reference dependent model can reconcile his 2005 finding that drivers stopping probabilities are significantly related to hours but not income with the negative wage elasticity of hours found by colin camerer et al 1997 and farber 2005 2008 the model yields sensible estimates that avoid farber s 2008 criticism that drivers income targets are too unstable to allow a useful reference dependent model of labor supply

are long term wage elasticities of labor supply more negative than short term ones standard models imply that the wage elasticity of labor supply is more negative the longer a wage change lasts i observe decreasing daily hours during short term wage increases but not during a long term one daily income goals adjusted in the long term

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

clean energy growth nexus in sub saharan africa evidence from cross sectionally dependent heterogeneous panel with structural breaks abstract this paper examines the existence and nature of a causality relationship between clean energy consumption and economic growth for a panel of eleven sub saharan african countries over the period 1971 2007 we apply the panel unit root test that accounts for the presence of multiple structural breaks 13 and the newly developed panel cointegration methodology which allows for cross section dependence and multiple structural breaks 38 as well as a bootstrap corrected granger causality test the estimation results show that there is cointegration between clean energy consumption and economic growth further the results from the panel causality tests indicate that there is indeed a unidirectional granger causal flow from clean energy consumption to economic growth

revisiting the role of tourism and globalization in environmental degradation in china fresh insights from the quantile ardl approach abstract ascertaining sustainable development is a major issue across the globe and the economic growth pattern achieved is a predominant reason behind this the globalization led economic growth achieved by the emerging economies might not be ecologically sustainable as globalization might not have been utilized as a policy tool moreover a sound policy calls for considering the entire data spectrum for the analysis which is largely ignored in the literature this research contributes to the literature by proffering a policy framework for the emerging economies by analyzing the impact of globalization and tourism on environmental degradation by considering the chinese context as a sample following the quantile autoregressive distributed lag model the impact of economic growth globalization and tourism on greenhouse gas emissions carbon dioxide emissions and the ecological footprint in china over 1978q1 2017q4 are analyzed the results demonstrate that economic growth stimulates environmental degradation while the presence of environmental kuznets curve is also validated moreover tourism has been found to exert positive environmental externalities while globalization exerts negative environmental externalities based on the outcomes of the research a comprehensive policy framework has been suggested following which the chinese economy might be able to attain the objectives of sustainable development goals 7 8 and 13

drivers of disruption estimating the uber effect abstract a frequent belief is that the rise of so called gig work has led to the displacement of workers in a wide range of traditional jobs this paper examines the impacts of the flagship of the gig economy uber on workers employed in conventional taxi services our analysis exploits newly collected data on the staggered rollout of uber across metropolitan areas in the united states and a difference in differences design to document that incumbent taxi drivers experienced a relative earnings decline of about 10 percent subsequent to uber s entry into a new market while there are no significant effects on their labor supply additional evidence from a battery of placebo tests event study estimates and specifications using google trends data to capture differences in treatment intensity underlines these findings a triple differences design that compares changes among taxi drivers relative to bus tractor and truck drivers that were unaffected by the arrival of uber provides further supporting evidence that the diffusion of uber has reduced the earnings potential of incumbent drivers in conventional taxi services in the united states

adjustment costs firm responses and micro vs macro labor supply elasticities evidence from danish tax records we show that the effects of taxes on labor supply are shaped by interactions between adjustment costs for workers and hours constraints set by firms we develop a model in which firms post job offers characterized by an hours requirement and workers pay search costs to find jobs we present evidence supporting three predictions of this model by analyzing bunching at kinks using danish tax records first larger kinks generate larger taxable income elasticities second kinks that apply to a larger group of workers generate larger elasticities third the distribution of job offers is tailored to match workers aggregate tax preferences in equilibrium our results suggest that macro elasticities may be substantially larger than the estimates obtained using standard microeconometric methods

is tomorrow another day the labor supply of new york city cabdrivers the labor supply of taxi drivers is consistent with the existence of intertemporal substitution my analysis of the stopping behavior of new york city cabdrivers shows that daily income effects are small and that the decision to stop work at a particular point on a given day is primarily related to cumulative daily hours to that point this is in contrast to the analysis of camerer et al who find that the daily wage elasticity of labor supply of new york city cabdrivers is substantially negative implying large daily income effects this difference in findings is due to important differences in empirical methods and to problems with the conception and measurement of the daily wage rate used by camerer et al

energy innovation and renewable energy consumption in the correction of air pollution levels abstract this study analyses the relationship between economic growth and environmental pollution specifically it investigates the presence of an environmental kuznets curve ekc in 17 oecd countries over the period of 1990 2012 the results confirm the existence of an n shaped ekc relationship between income and environmental degradation the study offers a novel methodological contribution that makes it possible to explain the environmental pollution process through the analysis of low carbon technologies this demonstrates how income levels affect energy consumption and how higher energy demand leads to a larger share of fossil sources in the energy mix and thus increased greenhouse gas ghg emissions the effect on per capita ghg emissions is explored in a model containing a dampening variable that moderates the relationship between energy consumption and income this empirical evidence helps to explain the interaction between energy regulation economic growth and carbon emissions this study also confirms the positive effect that energy innovation process exerts on environmental pollution finally it is noted that renewable energy sources help to improve air quality

reference dependent behaviour of paua abalone divers in new zealand we study dynamic labour supply using data on paua abalone divers in new zealand the divers face stable flat prices per kilogram after each catch but experience transitory wage changes due to varying weather and water conditions and are free to vary their daily working hours and display an intermittent working pattern we find nonlinear wage elasticities rejecting the standard neo classical prediction that these divers should work long hours during days when wages are high and quit early during days when hourly wages are low we explore potentially distorting factors but find little evidence applying k szegi and rabin s 2006 theory where workers have both income and hours targets could explain our result in particular our divers appear to be primarily guided by the hours target

behavioral economics and public policy a pragmatic perspective the debate about behavioral economics the incorporation of insights from psychology into economics is often framed as a question about the foundational assumptions of economic models this paper presents a more pragmatic perspective on behavioral economics that focuses on its value for improving empirical predictions and policy decisions i discuss three ways in which behavioral economics can contribute to public policy by oering new policy tools improving predictions about the eects

income targeting and farm labor supply there is considerable anecdotal evidence that farm workers who are paid by piece rate tend to income target or work only until they achieve a certain amount of daily income and then stop work we estimate reduced form and structural models derived from the reference dependent preference model of koszegi and rabin 2006 to test the income targeting hypothesis using data from the national agricultural workers survey naws we find evidence that supports the income targeting hypothesis in both the reduced form and structural econometric models our findings suggest that even higher piece rates may not help the widely reported shortage of agricultural labor on the intensive margin as labor supply curves can be backward bending

negative income taxes inequality and poverty we use a neoclassical growth model with heterogeneous agents to analyze the redistributive effects of a negative income tax system which combines a flat rate tax with a fully refundable credit demogrant we show that changing the demogrant to output ratio causes significant changes in the distribution of income specifically we find that increasing the demogrant to output ratio sharply reduces the level of inequality as well as both relative and absolute poverty all measured in terms of post tax total income however these reductions in inequality and poverty come at the expense of a significant reduction in output

loss aversion under prospect theory a parameter free measurement agrowing body of qualitative evidence shows that loss aversion a phenomenon formalized in prospect theory can explain a variety of field and experimental data quantifications of loss aversion are however hindered by the absence of a general preference based method to elicit the utility for gains and losses simultaneously this paper proposes such a method and uses it to measure loss aversion in an experimental study without making any parametric assumptions thus it is the first to obtain a parameter free elicitation of prospect theory s utility function on the whole domain our method also provides an efficient way to elicit utility midpoints which are important in axiomatizations of utility several definitions of loss aversion have been put forward in the literature according to most definitions we find strong evidence of loss aversion at both the aggregate and the individual level the degree of loss aversion varies with the definition used which underlines the need for a commonly accepted definition of loss aversion

here comes the rain again weather and the intertemporal substitution of leisure i revisit the intertemporal labor supply framework using exogenous variations in daily weather to see how time at work varies with rain in my model a rainy day is associated with a lower enjoyment of leisure effectively increasing wages and bringing more hours at work i test the model using data from the american time use survey supplemented with daily weather i find that on rainy days men shift on average 30 minutes from leisure to work computations give a rough estimate of the intertemporal elasticity of labor supply of around 0 01 in line with the rest of the literature

the political economy of high income taxation capital taxation path dependence and political institutions in denmark denmark s income tax burden as the percentage of gdp is larger than the total tax burden of the united states and it has increased further after 1980 how can this be explained given increasing tax competition and widespread views that strong reliance on regressive taxes was conducive to building and maintaining large tax and welfare states the article highlights three factors first large income taxes are feasible if the capital tax burden is moderated within the income tax second the effective capital income tax burden that had developed up to the early 1980s was extremely low so that subsequent tax reforms could cut marginal tax rates on mobile types of capital income while increasing tax revenue third drastic changes in the legal structure of the income tax and stability in aggregate tax policy outcomes were facilitated by proportional representation and legislative majority rule

reference dependent job search evidence from hungary we propose a model of job search with reference dependent preferences with loss aversion relative to recent income the reference point in this model newly unemployed individuals search hard since consumption is below their reference point over time though they get used to lower income and thus reduce their search effort in anticipation of a benefit cut their search effort rises again then declines once they get accustomed to the lower postcut benefit level the model fits the typical pattern of exit from unemployment even with no unobserved heterogeneity to distinguish between this and other models we use a unique reform in the unemployment insurance ui benefit path in 2005 hungary switched from a single step ui system to a two step system with overall generosity unchanged the system generated increased hazard rates in anticipation of and especially following benefit cuts in ways the standard model has a hard time explaining we estimate a model with optimal consumption endogenous search effort and unobserved heterogeneity the reference dependent model fits the hazard rates substantially better than plausible versions of the standard model including habit formation our estimates indicate a slow adjusting reference point and substantial impatience likely reflecting present bias jel codes d03 j64 j65

labor supply of new york city cabdrivers one day at a time life cycle models of labor supply predict a positive relationship between hours supplied and transitory changes in wages because such changes have virtually no effect on life cycle wealth previous attempts to test this hypothesis empirically with time series data have not been supportive estimated elasticities are typically negative or nonsignificant such analyses however are vulnerable to measurement error and other estimation problems we use data on daily observations of wages and hours for new york city cab drivers to estimate the supply response to transitory fluctuations in wages cab drivers decide daily how many hours to supply and face wages that are positively correlated within days but largely uncorrelated between days using these data our central finding is that wage elasticities are persistently negative from 5 to 1 in three different samples even after correcting for measurement error using instrumental variables these negative wage elasticities challenge the notion that cab drivers trade off labor and leisure at different points in time and question the empirical adequacy of life cycle formulations of labor supply

renewable energy policies and contradictions in causality a case of next 11 countries abstract numerous studies on the causal relationship between economic growth energy consumption and carbon dioxide co2 emissions have shown divergence in policy recommendations which arises mainly due to the choice of methodology and the period of study this inconclusiveness in policy prescriptions might turn out to be critical when the renewable energy policies of the developing nations are considered our study analyses the causal relationship between economic growth carbon emissions fossil fuel and renewable energy consumption in next 11 countries during the period of 1990 2016 along with conducting parametric and non parametric causality tests together introducing the geweke 1982 causality test in the literature of energy economics we attempt to establish a wholesome aspect of policy design by comparing and complementing results of different causality analysis and how the causality directions should comply with the context setting our empirical evidence confirms that robust renewable energy policy can be designed by complementing the various causality test results rather than focusing on one particular causality test

interplay between technological innovation and environmental quality formulating the sdg policies for next 11 economies abstract since the inception of sustainable development goals sdgs the next 11 n11 countries are facing difficulties in attaining the sdg objectives as maintaining the environmental quality has been a challenge for them in this study we have revisited the technology policies of these countries and in doing so we have tried to address the problem of environmental degradation while addressing the issues of sustained economic growth clean and affordable energy and quality education in this pursuit we have designed two indices for environmental degradation and technological advancement and then analyzed the association between them following the environmental kuznets curve ekc hypothesis the empirical analysis has been done by ipat framework and by using bootstrapped quantile regression and rolling window heterogeneous panel casualty tests over a period of 1990 2017 following the results obtained from the analysis we have tried to address the objectives of sdg 13 sdg 4 sdg 8 sdg 9 sdg 7 and sdg 10

reference points and effort provision a key open question for theories of reference dependent preferences is what determines the reference point one candidate is expectations what people expect could affect how they feel about what actually occurs in a real effort experiment we manipulate the rational expectations of subjects and check whether this manipulation influences their effort provision we find that effort provision is significantly different between treatments in the way predicted by models of expectation based reference dependent preferences if expectations are high subjects work longer and earn more money than if expectations are low

changes in risk and the demand for saving abstract how does risk affect saving empirical work typically examines the effects of detectible differences in risk within the data how these differences affect saving in theoretical models depends on the metric one uses for risk for labor income risk second degree increases in risk require prudence to induce increased saving demand however prudence is not necessary for first degree risk increases and not sufficient for higher degree risk increases for increases in interest rate risk a precautionary effect and a substitution effect need to be compared this paper provides necessary and sufficient conditions on preferences for an n th degree change in risk to increase saving
