idiosyncratic and common shocks to investment decisions this paper shows how microeconomic data on investment plans can be used to study the structure of risk faced by firms revisions of investment plans form a martingale and thus reveal the underlying shocks driving investment we decompose revisions in investment plans into micro sector and aggregate shocks and exploit stock market data to distinguish between structural valuerelated shocks and measurement error in investment revisions using panel data for us firms we find that microshocks are not the dominant source of risk in investment decisions and that much of the observed microvariation is actually due to heterogeneity in firm level responses to aggregate shocks firms are able to diversify most idiosyncratic investment risk and they do not appear to be liquidity constrained

relative price variability and inflation uncertainty the uk case this study applies the time varying volatility model to uk gdp deflators and compares it with the traditional inflation uncertainty measurement of relative price variability the link between relative price variability and time varying volatility is studied and established moreover inflation uncertainty is found to be highly persistent in duration and plausibly asymmetric to previous shocks at both disaggregate and aggregate levels

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

optimal task assignments with loss averse agents abstract this paper studies optimal task assignments in a setting where agents are expectation based loss averse according to koszegi and rabin 2006 2007 and are compensated according to an aggregated performance measure in which tasks are technologically independent we show that the optimal task assignment is determined by a trade off between paying lower compensation costs and restricting the set of implementable effort profiles under multitasking we show that loss aversion combined with how much the marginal cost of effort in one task increases with the effort chosen in other tasks determines when multitasking saves on compensation costs but results in an implementation problem

working over time dynamic inconsistency in real effort tasks experimental tests of dynamically inconsistent time preferences have largely relied on choices over time dated monetary rewards several recent studies have failed to nd the standard patterns of present bias however such monetary studies contain oftendiscussed confounds in this paper we sidestep these confounds and investigate choices over consumption real eort in a longitudinal experiment we pair this eort study with a companion monetary discounting study we conrm very limited time inconsistency in monetary choices however subjects show considerably more present bias in eort furthermore present bias in the allocation of work has predictive power for demand of a meaningfully binding commitment device therefore our ndings validate a key implication of models of dynamic inconsistency with corresponding policy implications

diffusion of technical change and the decomposition of output into trend and cycle in this paper we argue that modelling the trend component in real gnp as a random walk is inconsistent with its interpretation as productivity growth as an alternative we specify the trend as an arima whose impulse response function follows an s shaped pattern reflecting the process of diffusion of technical change such an arima is employed to build and estimate an ucarima using usa postwar quarterly data we find that our model although more parsimonious fits the data equally well than the standard random walk plus ar 2 cycle moreover our model has a very low cycle trend variance ratio

friedman s plucking model of business fluctuations tests and estimates of permanent and transitory components in milton friedman s model output cannot exceed a ceiling level but occasionally is plucked downward by recession implying fluctuations are asymmetric recessions transitory and recessions duration dependent though expansions are not the empirical literature lends support but formal modeling has been absent the econometric model presented here encompasses both plucking and symmetric fluctuations around a stochastic trend we find gdp is well characterized by the plucking model implied recessions correspond to nber reference cycles and no role for symmetric cycles decomposition of the unemployment rate reveals a corresponding asymmetry and timing paths of ceiling output and trend unemployment are presented

the behavioralist visits the factory increasing productivity using simple framing manipulations recent discoveries in behavioral economics have led to important new insights concerning what can happen in markets such gains in knowledge have come primarily via laboratory experiments a missing piece of the puzzle in many cases is parallel evidence drawn from naturally occurring field counterparts we provide a small movement in this direction by taking advantage of a unique opportunity to work with a chinese high tech manufacturing facility our study revolves around using insights gained from one of the most influential lines of behavioral research framing manipulations in an attempt to increase worker productivity in the facility using a natural field experiment we report several insights for example conditional incentives framed as both losses and gains increase productivity for both individuals and teams in addition teams more acutely respond to bonuses posed as losses than as comparable bonuses posed as gains the magnitude of this framing effect is roughly 1 that is total team productivity is enhanced by 1 purely due to the framing manipulation importantly we find that neither the framing nor the incentive effect lose their significance over time rather the effects are observed over the entire sample period moreover we learn that repeated interaction with workers and conditionality of the bonus contract are substitutes for sustenance of incentive effects in the long run this paper was accepted by gerard p cachon decision analysis

a new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle abstract this paper introduces a general procedure for decomposition of non stationary time series into a permanent and transitory component allowing both components to be stochastic the permanent component is shown to be a random walk with drift and the transitory or cyclical component is a stationary process with mean zero the decomposition methodology which depends only on past data and therefore is computable in real time is applied to the problem of measuring and dating business cycles in the portwar u s economy we find that measured expansions and contractions are of roughly equivalent duration and that our dating of cyclical episodes tends to lead the traditional nber dating and to a lesser extent the growth cycle chronology of zarnowitz and boschan 1977

inventories and asymmetric business cycle fluctuations in the uk a structural approach this paper investigates the movement of manufacturing inventories and production over the business cycle to arrive at an asymmetric structural equilibrium correction model initially cross correlation coefficients and deepness and steepness tests for skewness are utilized to present descriptive statistics of the time series cointegration analysis is performed on each disaggregate inventory by stage of production finished goods work in progress and raw materials with a set of explantory variables restricted cointegration vectors are added to the symmetric and non symmetric specifications of the structural equilibrium correction model these are compared by parameter constancy tests and one step ahead forecasts

asymmetric phase shifts in u s industrial production cycles abstract we identify cyclical turning points for 74 u s manufacturing industries and uncover new empirical regularities a industries tend to comove between expansion and contraction phases over the business cycle b clusters of industry turning points are highly asymmetric between peaks and troughs troughs are much more concentrated and sharper than peaks c the temporal pattern of phase shifts across industries supports the spillovers through input output linkages and d macroeconomic shocks such as unanticipated changes in monetary policy government spending oil prices and financial conditions are significant drivers of industrial phase shifts

sectoral price rigidity and aggregate dynamics abstract this paper studies the business cycle implications of sectoral heterogeneity in price rigidity using a highly disaggregated multi sector model the model is estimated by the simulated method of moments using a mix of aggregate and sectoral u s data the frequencies of price changes implied by our estimates are consistent with those reported in micro based studies we show that heterogeneity in price rigidity is the primary factor explaining the heterogeneity in the responses of sectoral output and inflation to a monetary policy shock we also find that ignoring sectoral heterogeneity in price rigidity leads to the mismeasurement of the relative importance of aggregate and sector specific shocks in aggregate and sectoral fluctuations

self control and the development of work arrangements a significant part of the development experience is the change in the way work is structured to use a historical example the industrial revolution involved workers moving from agriculture to manufacturing from working on their own to working with others in factories and from flexible work hours to rigid work days how are we to understand these changes why did they occur what impacts did they have on labor productivity and possibly growth in answering questions such as these economic theories draw on different assumptions about aggregate production market failures and innovation yet almost all rely on one of two determinants of labor productivity human capital and incentives human capital theories broadly construed emphasize how work arrangements utilize the distribution of human capital and in learning models facilitate its development incentive theories again broadly construed emphasize how workplace arrangements align worker payoffs to minimize moral hazard in this paper we bring together and advance a growing literature on a third feature worker self control individuals may not be able to work as hard as they would like some workplace arrangements may make self control problems more severe while others may ameliorate them below we describe evidence from a field experiment broadly supportive of the selfcontrol perspective we then argue that many work arrangements can be understood differently through this perspective specifically we

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

an endowment effect for risk experimental tests of stochastic reference points recent models of reference dependent preferences indicate that expectations may play a prominent role in the presence of behavioral anomalies a subset of such expectations based models predicts an endowment effect for risk that risk attitudes differ when reference points change from certain to stochastic in two purposefully simple risk preference experiments eliminating often discussed confounds i demonstrate both between and within subjects such an endowment effect for risk these results provide needed separation between expectations based reference dependent models allow for evaluation of recent theoretical extensions and may help to close a long standing debate in decision science on inconsistency between utility elicitation methodologies

rainwater harvesting and groundwater conservation when endogenous heterogeneity matters in this paper we focus on resource conservation in a model of decentralized management of groundwater and rainwater we show that a conservation policy may have opposite effects on the level of the resource depending on the outcome of the decentralized management more precisely we consider identical farmers who can use two water resources groundwater and or rainwater and we study the symmetric and asymmetric feedback stationary nash equilibria of the dynamic game we show that a subsidy on the use of rainwater may increase the level of the aquifer at the symmetric equilibrium whereas it decreases the level of the aquifer at the asymmetric equilibrium this suggests that the usual focus on interior symmetric equilibria in dynamic games may provide misleading policy implications

trade exposure export intensity and wage volatility theory and evidence this paper addresses the link between trade exposure and wage volatility first it shows in a simple model that trade exposure magnifies the impact of domestic productivity shocks on industry specific labor demand particularly for the less export intensive industries and that if labor is not perfectly mobile this implies a rise in wage volatility then it tests these predictions using industry data the empirical results confirm that wage volatility increases with an industry s degree of openness and that it declines with an increase in the industry s export intensity

stochastic trends and economic fluctuations are business cycles mainly the result of permanent shocks to productivity this paper uses a long run restriction implied by a large class of real business cycle models identifying permanent productivity shocks as shocks to the common stochastic trend in output consumption and investment to provide new evidence on this question econometric tests indicate that this common stochastic trend cointegration implication is consistent with postwar u s data however in systems with nominal variables the estimates of this common stochastic trend indicate that permanent productivity shocks typically explain less than half of the business cycle variability in output consumption and investment copyright 1991 by american economic association

my reference point not yours abstract reference points formed by initial endowments influence individual decisions this experiment tests whether an individual can predict the behavior of other people who have different reference points despite financial incentives for being correct players fail to imagine themselves in another person s shoes a low endowment player generally cannot predict the behavior of those who were assigned high endowments and vice versa when asked about group behavior instead of considering the perspectives of others a low endowment player predicts that all others will act as if they all had low endowments this controlled experiment helps explain why it is difficult to understand the perspectives of other people while also demonstrating that it is possible when a player is specifically prompted to consider an individual in a different circumstance

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

sectoral shifts and cyclical unemployment a reconsideration sectoral shifts and cyclical unemployment a reconsideration the debate over the relative importance of sectoral and aggregate shocks in explaining fluctuations in the aggregate unemployment rate has centered on the relationship between unemployment job vacancies and the dispersion of sectoral employment growth rates which proxies for sectoral shocks this paper examines some possible theoretical relationships between these variables and after decomposing unemployment into components attributable to sectoral and aggregate shocks estimates the importance of each if finds that fluctuations in unemployment are principally caused by aggregate shocks but sectoral shifts explain a significant albeit steady amount of unemployment i introduction in a controversial paper lillien 1982 argued that much of the rise in aggregate unemployment experienced in the 1970s and 1980s was attributable to increases in the natural rate of unemployment these increases he said arose from shifts of demand between the different sectors of the national economy these demand shifts increased unemployment because labor market frictions prevented the immediate reallocation of workers from declining sectors to expanding sectors lillien used a dispersion index of sectoral employment growth rates as a proxy for the extent of sectoral shifts and found that aggregate unemployment could be explained by this dispersion with a positive distributed lag given the much discussed changing composition of output and employment in the u s this interpretation of unemployment quickly won adherents such as barro 1984 more recent work by abraham and katz 1986 challenges this view they argue that the rise in aggregate unemployment was attributable to aggregate demand disturbances they showed that if sectors had different cyclical sensitivities aggregate demand disturbances such as those resulting from monetary policy or fluctuations in animal spirits could produce counter cyclical fluctuations in the dispersion of sectoral employment growth rates the finding that unemployment was a distributed lag of this dispersion did not therefore distinguish between the two hypotheses instead abraham and katz found vacancy rates to be negatively related to dispersion with a distributed lag they interpreted this result as confirmation of the aggregate demand hypothesis since it was consistent with a movement along the beveridge curve 1 my paper further explores the relationships between sectoral shifts aggregate unemployment and aggregate vacancies the theoretical section demonstrates that sectoral shifts are also consistent with a movement along the beveridge curve and a negative relation between vacancies and the dispersion of sectoral employment growth rates this result potentially invalidates abraham and katz s claim and at the same time provides a novel explanation of the beveridge curve in the empirical section i use the implications of the two hypotheses to decompose the dispersion of sectoral employment growth rates into parts attributable to sectoral shifts and aggregate shocks respectively these new measures are then used to estimate the relative contributions of sectoral shifts and aggregate disturbances to aggregate unemployment this paper is linked to an emerging literature on the sources of macroeconomic fluctuations the seminal paper by long and plosser 1983 showed how real business cycle models could explain comovements of output across sectors on the basis of sector specific shocks in a subsequent paper long and plosser 1987 sought to identify the relative importance of aggregate versus sector specific shocks using a single factor model of output growth they found that aggregate shocks explained only a relatively small amount of the convariation of output across sectors and concluded that sectoral shocks are largely responsible for cyclical fluctuations

sources of output fluctuations in the united states during the inter war and post war years abstract this paper attempts to decompose the sources of fluctuations in industry output into 1 an aggregate national shock 2 industry group specific shocks and 3 idiosyncratic factors the empirical methodology is the engle watson dynamic mimic model the work is motivated as an attempt to compare empirically aggregate single factor theories of the cycle with real business cycle theories emphasizing technology shocks disaggregate data from the inter war and post war periods are examined conclusions on the relative importance of the various shocks seem to be dependent on the period being considered the single index theory of the cycle seems more appropriate for the inter war period

asymmetric size dependent effects of the output gap on inflation us evidence from the last half a century this article examines asymmetric size and sign dependent effects of the output gap on the us quarterly inflation rate using data from the last half a century 1959q2 2013q1 consistent with previous studies it is found that the consumer price index is cointegrated with the unit labour cost and the price of oil a short run dynamic model is then estimated in which variations in the output gap are divided into three groups large positive large negative and small medium positive negative the results provide convincing evidence that only sufficiently large positive or negative variations of the output gap can significantly influence inflation put otherwise relatively small to medium changes in the output gap exert no significant impact on inflation and if not separated they can somewhat obscure the significant effects associated with large variations of the output gap this study can lead to greater consensus on the inflation output gap nexus the findings remain robust despite the use of differen

present or future incentives on the optimality of fixed wages with moral hazard abstract this paper uses a laboratory experiment to show that principals can defer all incentives for present effort to future payments and thus pay fixed wages and still motivate workers at the least cost whenever outcomes are observable this result contrasts with the prediction of the classical moral hazard model according to which future and present payments must be made contingent on present outcomes to induce effort at the least cost even though risk aversion cannot explain this result i estimate an expectation based reference dependent model to show that it is consistent with loss aversion

goal setting and self control abstract this paper addresses the role of non binding goals to attenuate time inconsistency present biased agents have linear reference dependent preferences and endogenously set a goal that is the reference point they face an infinite horizon optimal stopping problem in continuous time when there is sufficient commitment to expectation based goals goal setting attenuates the present biased agent s tendency to stop too early and may even lead an agent to wait longer than the first best in particular reference dependence is strictly worse for a time consistent agent notably none of the effects of goal setting require loss aversion

the aggregate effects of sectoral reallocations abstract can a one time permanent change in the fundamentals behind the sectoral composition of the economy prompt an aggregate downturn can this downturn be non negligible even if one uses us data to determine the relative size of gross vs net job flows and the importance of job creation costs can one consider the military build down of the 1990s as a plausible cause for the 1990 1991 recession do sectoral reallocations generate responses that are qualitatively similar to productivity shocks we use a variant of the mortensen pissarides 1994 review of economic studies 61 397 415 job creation destruction model calibrate it to us labor market data and run experiments that suggest one can answer yes to all these questions

using loss aversion to incentivize energy efficiency in a principal agent context evidence from a field experiment abstract promoting energy efficient behavior of agents in a principal agent context simultaneously decreases costs for firms and mitigates co2 emissions along this line we analyze the effect of incentive framing on energy efficient driving behavior our results contribute to the understanding of the drawbacks of loss framing in a situation with persistent labor market relations an extremely low bonus and heterogeneous prior performance the introduction of a bonus framed as a gain outperforms that of a bonus framed as a loss

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

working for the warm glow on the benefits and limits of prosocial incentives abstract we study whether using prosocial incentives where effort is tied directly to charitable contributions may lead to better performance than standard incentive schemes in a real effort task individuals indeed work harder for charity than for themselves but only when incentive stakes are low when stakes are raised effort increases when individuals work for themselves but not when they work for others and as a result the difference in provided effort disappears individuals correctly anticipate these effects choosing to work for charity at low incentives and for themselves at high incentives the results are consistent with warm glow giving and have implications for optimal incentive design

optimal management of a renewable and replaceable resource the case of coastal groundwater the nonrenewable with backstop model of resource management is extended to cover renewables and applied to the case of coastal groundwater in the optimal management trajectory efficiency price exceeds extraction cost by the sum of scarcity rent and drawdown cost the latter remaining large even after the backstop price is reached in the case of rising demand optimal management may call for a stage of conservation followed by a stage of drawdown

an examination of business cycle features in uk sectoral output this article examines business cycle features of uk gross domestic product gdp sectors with regard to trends cycles and growth the empirical study adopts the kalman filter to decompose these gdp sectors into trend and cycle components the general model of this study encompasses a number of alternative specifications about trend growth therefore accommodating diverse views on growth there is reasonable support in the results for a mean reverting stochastic growth model for the uk economy the characteristics in trends and cycles of uk gdp sectors are discussed focusing on their similarities and differences around business cycles

willingness to pay and willingness to accept how much can they differ comment i agree with the point made by edoh y amiran and daniel a hagen 2003 that there can be a substantial or even infinite divergence between the wta and wtp for a public good even where there is a nonzero elasticity of substitution between market goods and the public good provided that the indifference curves are asymptotically bounded with respect to market goods in the manner they describe this is an important point they are also correct to point out that the elasticity of substitution is a local concept whereas their asymptotic boundedness condition applies also for discrete changes my 1991 paper used a local analysis because it was following the structure of the analysis in robert d willig 1976 and alan randall and john r stoll 1980 i wanted to show that while randall and stoll appeared to extend willig s local result on wta versus wtp from price changes to changes in the quantity of a public good the relevant elasticity was in fact different and involved the substitution elasticity as well as the income elasticity i view these points by amiran and hagen as not two separate results but essentially the same result their asymptotic boundedness condition generalizes my zero elasticity of substitution condition to discrete changes the asymptotic boundedness condition can be expressed as follows assuming a bivariate utility function u x q and given a reference point x q associated with a reference utility level u u x q there exists some q q such that for all q q there exists no x such that u x q u in other words no amount of x can substitute for the reduction in public good from q to q q in the case of a zero elasticity of substitution q q but as amiran and hagen show in their theorem 1 this is unnecessarily restrictive when dealing with a discrete reduction in q furthermore their theorem 2 can be viewed as a special case of their theorem 1 in which q 0 which makes q an essential commodity it is well known in consumer theory that the wta to avoid the loss of an essential market good is infinite their theorem 2 extends this result to the case of an essential nonmarket good but as their theorem 1 shows essentialness is not necessary for an infinite wta the boundedness condition is the key and this implies a fundamental lack of substitutability between money market goods and the public good

the role of international factors in the business cycle a multi country study abstract empirical research has been conducted on the various theories of the business cycle over many countries however very little research has attempted to undertake a multi country disaggregate investigation into the sources of output change this paper decomposes fluctuations in industry output in a particular country into 1 a nation specific shock 2 an industry specific shock 3 a common shock and 4 an idiosyncratic factor using a dynamic factor analysis state space approach the paper finds that the industry specific impulse explains a significant but small part of the variance of the forecast error this provides limited support for the disaggregated real business cycle paradigm

a dynamic approach to pes pricing and finance for interlinked ecosystem services watershed conservation and groundwater management a theory of payment for ecosystem services pes pricing consistent with dynamic efficiency and sustainable income requires optimized shadow prices since ecosystem services are generally interdependent this requires joint optimization across multiple resource stocks we develop such a theory in the context of watershed conservation and groundwater extraction the optimal program can be implemented with a decentralized system of ecosystem payments to private watershed landowners financed by efficiency prices of groundwater set by a public utility the theory is extended to cases where land is publicly owned conservation instruments exhibit non convexities on private land or the size of a conservation project is exogenous in these cases conservation investment can be financed from benefit taxation of groundwater consumers while volumetric conservation surcharges induce inefficient water use a dynamic lump sum tax finances investment without distorting incentives since the optimal level of conservation is generated as long as payments are correct at the margin any surplus can be returned to consumers through appropriate block pricing the present value gain in consumer surplus generated by the conservation induced reduction in groundwater scarcity serves as a lower bound to the benefits of conservation without explicit measurement of other benefits such as recreation biodiversity and cultural values

intertemporal incentives under loss aversion this paper studies the intertemporal allocation of incentives in a repeated moral hazard model with reference dependent preferences as in k oszegi and rabin 2009 besides consumption utility the agent experiences utility from the change in his beliefs about present and future eort and income when eort plans are rational the prospect of being disappointed by the outcome realization equals that of being pleasantly surprised and hence the loss averse agent is on net hurt by news in contrast to the prediction with classical preferences but consistent with real world contracts if consumption utility is not too concave and news about present income carries suciently larger weight in utility than news about future income a contract setting a current

gain versus loss contracts does contract framing affect agents reciprocity abstract loss contracts are rarely observed in practice although research suggests that they induce higher effort compared to gain contracts we experimentally examine one potential reason for this scarcity agents reciprocity toward the principal might be negatively affected by loss contracts first agents worked on a real effort task under either a gain or a loss contract second principals and agents played a trust game we find that loss contracts induce more effort and thus a higher payoff for the principal in the real effort task however we do not find a spillover effect of contract framing in the trust game differences in reciprocity are small in size and not significant thus they cannot explain the rare use of loss contracts in practice

labor economics and the psychology of organizations this essay is a discussion of how economists are attempting to understand institutions within the organizations of the labor market the institutions and issues discussed include mandatory retirement discontinuous jumps in wages pay compression rights of tenure up or out hierarchies timing of raises promotions and evaluations the existence of partnerships the use of bonuses vs penalties and pay as a motivator

regional and sectoral evidence of the macroeconomic effects of labor reallocation a panel data analysis this paper revisits the sectoral shifts hypothesis by examining unemployment fluctuations for 48 u s states over the period 1990 01 2011 12 we develop a panel approach that incorporates dynamics parameter heterogeneity aggregate factors and cross sectional dependence our findings provide support for a positive and significant effect of the employment dispersion index on unemployment this outcome is robust under alternative specifications and measures of employment dispersion the empirical evidence corroborates the presence and relevance of cross sectional dependence and heterogeneity among states the results show that once unobserved common factors and cross state heterogeneity are taken into account labor reallocation has a significant effect on unemployment that is half the size of the estimate when cross sectional dependence is not taken into account

choking under time pressure the influence of deadline dependent bonus and malus incentive schemes on performance abstract many economically relevant activities are executed under notable time pressures incentivized deadlines are often the reason people feel pressured in such an environment individual preferences can predict performance through a laboratory experiment we examine the predictive power of individual loss aversion on performance under deadline dependent incentives participants worked on a real effort task under two payoff equivalent contracts framed in bonus and malus terms the results show lower performance for individuals with high loss aversion when working under a malus contract these individuals needed more time to reply and were less able to avoid maluses than other individuals choking can explain this observed behavior

the cyclical component of u s economic activity quarterly data on industrial production and deflated gross national product in the united states from 1947 through 1985 are decomposed into independent nonstationary trend and stationary cycle components using kalman filtering and smoothing techniques estimates of the model parameters imply that at least half of the quarterly innovation in u s economic activity can be attributed to a stationary cyclical component that persists over periods of time as long as five years this finding is inconsistent with the hypothesis that most of the apparent variation in u s economic activity can be attributed to a nonstationary trend component

toward an understanding of the welfare effects of nudges evidence from a field experiment in the workplace social scientists have recently explored how framing of gains and losses affects productivity we conducted a field experiment in peri urban uganda and compare output levels across 1000 workers over isomorphic tasks and incentives framed as either losses or gains we find that loss aversion can be leveraged to increase the productivity of labor the estimated welfare costs of using the loss contract are quite modest perhaps because the loss contract is viewed as a soft commitment device

revising commitments field evidence on the adjustment of prior choices the very poor in developing countries often make intertemporal choices that seem at odds with their individual self interest there are many possible reasons why this paper investigates several of these reasons with a lab in the field experiment in rural malawi involving large stakes it makes two contributions first it constructs a new dependent variable revisions of prior choices regarding the allocation of future income this allows us to directly examine intertemporal choice revision and its determinants in particular this dependent variable permits a novel test for the existence of self control problems it turns out revisions of money allocations toward the present are positively associated with measures of present bias from an earlier baseline survey as well as the randomly assigned closeness in time to the first possible date of money disbursement second the paper investigates other potential determinants of revision aside from self control problems it finds little evidence that revisions of money allocations toward the present are associated with spousal preferences for such revision household shocks or the financial sophistication of respondents

tying odysseus to the mast evidence from a commitment savings product in the philippines we designed a commitment savings product for a philippine bank and implemented it using a randomized control methodology the savings product was intended for individuals who want to commit now to restrict access to their savings and who were sophisticated enough to engage in such a mechanism we conducted a baseline survey on 1777 existing or former clients of a bank one month later we offered the commitment product to a randomly chosen subset of 710 clients 202 28 4 percent accepted the offer and opened the account in the baseline survey we asked hypothetical time discounting questions women who exhibited a lower discount rate for future relative to current trade offs and hence potentially have a preference for commitment were indeed significantly more likely to open the commitment savings account after twelve months average savings balances increased by 81 percentage points for those clients assigned to the treatment group relative to those assigned to the control group we conclude that the savings response represents a lasting change in savings and not merely a short term response to a new product

regional income fluctuations common trends and common cycles this paper investigates trend and cycle dynamics in per capita income for the major u s regions during the 1956 1995 period cointegration and serial correlation common features information are used in jointly decomposing the series into trend and cycle components we find considerable differences in the volatility of regional cycles controlling for differences in volatility we find a great deal of comovement in the cyclical response for all regions but the far west possible sources underlying differences in regional cycles are explored such as the share of a region s income accounted for by manufacturing defense spending as a proportion of a region s income oil price shocks and the stance of monetary policy somewhat surprisingly we find that the share of manufacturing in a region seems to account for little of the variation in regional cycles relative to national cycles but manufacturing share differentially affects trend growth for four of the seven regions studied

nominal inertia and shock persistence in uk business cycles a structural var methodology is used for uk data to identify and map out the effects of innovations in the money supply employment output wages and prices moreover bands of two standard errors are computed for the impulse response functions so that comment may be made on the significance of the dynamic responses of the variables to the simulated shocks this allows conclusions to be drawn on the persistence of shocks results suggest that output variation is largely determined by aggregate demand shocks over the business cycle frequency importantly evidence is also found of rigidities in the form of price inertia and nominal wage stickiness

leveraging upfront payments to curb employee misbehavior evidence from a natural field experiment abstract we use a natural field experiment in which we hired over 2000 workers from an online labor market to explore how upfront payment affects worker motivation and misbehavior on the job we start with a simple theory that shows paying upfront can increase misbehavior through reducing the perceived costs of cheating but it can decrease misbehavior through generating a gift exchange effect motivated by the theory we designed a task that provided workers with opportunities to reciprocate or misbehave a unique aspect of our design is that we are permitted an opportunity to measure the curvature of the gift exchange value of the upfront payment our results suggest paying workers upfront induces a gift exchange effect that is concave in the share of total wage paid upfront moreover the impact is strong enough to suggest that small upfront payments are a cost effective means for an employer to curb employee misbehavior

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

energy backstop endogeneity and the optimal use of groundwater to meet the growing demand for freshwater many regions have increased groundwater pumping in recent years resulting in declining groundwater levels worldwide a promising development to address these declines is technical change regarding groundwater substitutes such as desalination and wastewater recycling however because these technologies are energy intensive optimal implementation also depends on future energy price trends we provide an operational model for the case of reverse osmosis seawater desalination in an application to the pearl harbor aquifer in hawaii we find that allowing the cost of desalination to increase at an average annual rate of 2 4 over the next century results in a substantially steeper efficiency price path for water the higher prices decrease optimal groundwater extraction and induce a slower head drawdown over a longer period of time thereby delaying the transition to desalination by over 30 years because the rise in energy costs exacerbates efficiency losses from under pricing any delay in implementing efficiency pricing will cause either a greater future increase in prices or the need for rationing reforming prices sooner rather than later may be more politically feasible given that consumers may be more amenable to a gradual rise in prices today than a sudden doubling or tripling of prices ten years from now using this as a foundation we outline a research agenda for extending the framework to other groundwater substitutes and for adapting to climate change

risk preferences are not time preferences risk and time are intertwined the present is known while the future is inherently risky this is problematic when studying time prefer ences since uncontrolled risk can generate apparently present biased behavior we systematically manipulate risk in an intertemporal choice experiment discounted expected utility performs well with risk but when certainty is added common ratio predictions fail sharply the data cannot be explained by prospect theory hyperbolic discounting or preferences for resolution of uncertainty but seem consistent with a direct preference for certainty the data suggest strongly a difference between risk and time preferences jel c91 d81 d91 understanding individual decision making under risk and over time are two foundations of economic analysis 1 in both areas there has been research to suggest that standard models of expected utility eu and exponential discounting are flawed or incomplete regarding time experimental research has uncovered evidence of a present bias or hyperbolic discounting frederick loewenstein and o donoghue 2002 regarding risk there are number of well documented departures from eu such as the allais 1953 common consequence and common ratio paradoxes an organizing principle behind expected utility violations is that they seem to arise as so called boundary effects where certainty and uncertainty are combined camerer 1992 harless and camerer 1994 and starmer 2000 indicate that violations of expected utility are notably less prevalent when all choices are uncertain this observation is especially interesting when considering decisions about risk taking over time in particular certainty and uncertainty are combined in intertemporal decisions the present is known and certain while the future is inherently risky this observation is problematic if one intends to study time preference in isolation from

sectoral versus aggregate shocks a structural factor analysis of industrial production using factor methods we decompose industrial production ip into components arising from aggregate and sector specific shocks an approximate factor model finds that nearly all of ip variability is associated with common factors we then use a multisector growth model to adjust for the effects of input output linkages in the factor analysis thus a structural factor analysis indicates that the great moderation was characterized by a fall in the importance of aggregate shocks while the volatility of sectoral shocks was essentially unchanged consequently the role of idiosyncratic shocks increased considerably after the mid 1980s explaining half of the quarterly variation in ip

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

sectoral shocks and business cycles a disaggregated analysis of output fluctuations in the uk in this paper we first show that it is possible to modify linear real business cycle models to allow for disaggregate industry specific factors in the generation of macroeconomic fluctuations we then try to determine the relative importance of aggregate and sectoral shocks by doing principal components analysis on the residuals from a var of output growth rates in 19 uk industrial sectors we find that a significant percentage of the innovations in sectoral output growths can be accounted for by a single unobserved component however since the model only sets an upper bound to the explanatory power of aggregate impulses the importance of using sectoral data to extract additional information to bear on the analysis of economic fluctuations is confirmed by our findings

do people anticipate loss aversion there is growing interest in the use of loss contracts that offer performance incentives as up front payments that employees can lose standard behavioral models predict a trade off in the use of loss contracts employees will work harder under loss contracts than under gain contracts but anticipating loss aversion they will prefer gain contracts to loss contracts in a series of experiments we test these predictions by measuring performance and preferences for payoff equivalent gain and loss contracts we find that people indeed work harder under loss than gain contracts as the theory predicts surprisingly rather than a preference for the gain contract we find that people actually prefer loss contracts in exploring mechanisms for our results we find suggestive evidence that people do anticipate loss aversion but select into loss contracts as a commitment device to improve performance using one bias loss aversion to address another dynamic inconsistency data as supplemental material are a
