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

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

the effect of inheritance receipt on retirement abstract this paper provides new evidence on how wealth shocks influence retirement behavior economic theory generally posits that leisure is a normal good yet it is difficult to obtain reliable empirical estimates of the wealth effect because wealth is correlated with numerous unobservable characteristics that affect labor supply we use inheritance receipt as a wealth shock and find that it is associated with a significant increase in the probability of retirement especially when the inheritance is unexpected this evidence has important implications for how public policies such as pension or tax reform may influence retirement behavior through the wealth effect

saving more in groups field experimental evidence from chile abstract we test the impact of a peer group program on savings in a sample of microcredit clients we conduct two randomized trials among these 2687 microcredit clients the first finds that a savings group treatment which combines public goal setting monitoring in the group and non financial rewards increases savings in a new savings account significantly the number of deposits grows 3 7 fold and the average balance almost doubles in contrast a more classical measure a substantially increased interest rate has no effect for most participants and raises the savings balance only for the very top of the distribution a second experiment conducted a year later tests an alternative delivery mechanism and shows that effects of similar size can be achieved through feedback text messages without meetings rewards or peer pressure given that participants are borrowing at 90 apr we discuss how and when saving more could be harmful or beneficial

expectations as endowments evidence on reference dependent preferences from exchange and valuation experiments while evidence suggests that people evaluate outcomes with respect to reference points little is known about what determines them we conduct two experiments that show that reference points are determined at least in part by expectations in an exchange experiment we endow subjects with an item and randomize the probability they will be allowed to trade subjects that are less likely to be able to trade are more likely to choose to keep their item in a valuation experiment we randomly assign subjects a high or low probability of obtaining an item and elicit their willingness to accept for it the high probability treatment increases valuation of the item by 20 30 copyright 2011 oxford university press

comment on risk preferences are not time preferences separating risk and time preference andreoni and sprenger 2012a b observe that utility functions are distinct for risk and time preferences and show that their findings are consistent with a preference for certainty we revisit this question in an enriched experimental setting in which subjects make intertemporal decisions under different risk conditions the observed choice behavior supports a separation between risk attitude and intertemporal substitution rather than a preference for certainty we further show that several models including epstein and zin 1989 chew and epstein 1990 and halevy 2008 exhibit such a separation and can account for the overall experimental findings jel c91 d81 d91 risk and time preferences are the cornerstones of economic analyses regarding risk preference expected utility eu has been the predominant theory in which the curvature of the utility index captures risk attitude regarding time preference discounted utility is the most widely used model in which the curvature of the utility index captures intertemporal substitution when risk and time are intertwined integrating the two theories yields discounted expected utility deu which evaluates a contingent consumption plan c c c 3 as follows

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 abcs of financial education experimental evidence on attitudes behavior and cognitive biases this paper uses a large scale field experiment in india to study attitudinal behavioral and cognitive constraints that stymie the link between financial education and financial outcomes the study complements financial education with i participant classroom motivation with pay for performance on a knowledge test ii intensity of treatment with personalized financial counseling and iii behavioral nudges with financial goal setting the analysis finds no impact of pay for performance but significant effects of both counseling and goal setting on real financial outcomes these results identify important complements to financial education that can bridge the gap between financial knowledge and financial behavior change

an evaluation of the swedish system of active labour market programmes in the 1990s we investigate the presence of short and long term effects from joining a swedish labor market program vis a vis more intense job search in open unemployment overall the impact of the program system is found to have been mixed joining a program has increased employment rates among participants a result robust to a misclassification problem in the data on the other hand it has also allowed participants to remain significantly longer on unemployment benefits and more generally in the unemployment system this being particularly the case for those entitled individuals entering a program around the time of their unemployment benefits exhaustion

every drop counts a water conservation experiment with hotel guests we implement a field experiment with hotel guests to measure the effects of nonprice interventions on water conservation and customer satisfaction in hotels guests have no direct pecuniary incentive to conserve water as consumers do at home where they pay their own water bills because hotels earn greater profits when they manage to convince guests to conserve guests may be suspicious of a hotel s stated social goal of water conservation by implementing behavioral interventions that address these challenges we find that our nudges can induce guests to reduce their water consumption even when no direct monetary incentive is provided using post stay customer surveys we detected no adverse effects on customer satisfaction due to these nudges jel d12 i31 q41 q50

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

residential electricity consumption behavior influencing factors related theories and intervention strategies abstract the proportion of residential electricity consumption in the total energy consumption has increased rapidly in the past decades all over the world it is becoming increasingly important to promote household energy conservation for the sustainable development of a country in the case of resource constraints this paper reviews and evaluates the existing research works which are related to the residential electricity consumption behavior particular attention is given to the following aspects 1 factors influencing residential electricity consumption in social psychology 2 theories of social psychology in understanding residential electricity consumption behavior 3 different interventions aiming at encouraging households to reduce electricity consumption finally we discuss the challenges and opportunities of research on residential electricity consumption behavior in the big data era

flexible parametric estimation of duration and competing risk models in this paper we specify and estimate a flexible parametric proportional hazards model the model specification is flexibly parametric in the sense that the baseline hazard is non parametric while the effect of the covariates takes a particular functional form we also add parametric heterogeneity to the underlying hazard model specification we specify a flexible parametric proportional competing risks model which permits unrestricted correlation among the risks unemployment duration data are then analysed using the flexible parametric duration and competing risks specifications we find an important effect arising from the exhaustion of unemployment insurance and significantly different hazards for the two types of risks new jobs and recalls

learning self control this article examines how a decision maker who is only partially aware of his temptations learns about them over time in facing temptations individuals use their experience to forecast future self control problems and choose the appropriate level of commitment i demonstrate that rational learning can be perpetually partial and need not result in full sophistication the main result of this article characterizes necessary and sufficient conditions for learning to converge to full sophistication i apply this result to a consumption savings environment in which a decision maker is tempted by present bias and establish a learning theoretic justification for assuming sophistication in this setting an individual who finds himself continuously repudiating his past plans may learn to distrust his future behavior and may do something about it strotz 1955

choice and procrastination author s o donoghue ted rabin matthew abstract recent models of procrastination due to self control problems assume that a procrastinator considers just one option and is unaware of her self control problems we develop a model where a person chooses from a menu of options and is partially aware of her self control problems this menu model replicates earlier results and generates new ones a person might forego completing an attractive option because she plans to complete a more attractive but never to be completed option hence providing a non procrastinator additional options can induce procrastination and a person may procrastinate worse pursuing important goals than unimportant ones

the dynamics of behavior change evidence from energy conservation abstract little is known about the effect of message framing on conservation behavior over time in a randomized controlled trial with residential households we use advanced metering and information technologies to test how different messages about household energy use impact the dynamics of conservation behavior down to the appliance level our results based on 374 million panel observations of kilowatt hour kwh electricity consumption for 118 households over 9 months show that differences in behavioral responses due to message framing become more significant over time we find that a health based frame in which households consider the human health effects of their marginal electricity use induced persistent energy savings behavior of 8 10 over 100 days whereas a more traditional cost savings frame drove sharp attenuation of treatment effects after 2 weeks with no significant savings versus control after 7 weeks we discuss implications for the design of effective information campaigns to engage households in conservation behavior

dynamic salience with intermittent billing evidence from smart electricity meters abstract digital tracking and the proliferation of automated payments have made intermittent billing more commonplace and the frequency at which consumers receive price quantity or total expenditure signals may distort their choices while this category of goods has expanded from household utilities toll road access and software downloads to standard consumption goods paid by credit card or other bill me later type systems we know surprisingly little about how these payment patterns affect decisions this paper exploits hourly household electricity consumption data collected by smart electricity meters to examine dynamic consumer behavior under intermittent expenditure signals households reduce consumption by 0 6 1 following receipt of an electricity bill but the response varies considerably by household type and season our results also suggest that spending reminders can reduce peak demand particularly during summer months we discuss the implications for energy policy when intermittent billing combined with inattention induces consumption cycles

goal setting and energy conservation abstract this paper develops a theoretical model of consumer demand for an energy conservation program that involves non binding self set goals we present evidence from a northern illinois goal setting program aimed at reducing residential electricity consumption which is difficult to reconcile with standard preferences and is broadly consistent with a model of present biased consumers with reference dependent preferences we find that the need for commitment is correlated with program adoption higher pre adoption consumption and lower responsiveness to goals consumers choosing realistic goals persistently save substantially more achieving savings of nearly 11 than those choosing very low or unrealistically high goals

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

information provision and consumer behavior a natural experiment in billing frequency abstract in this study i estimate a causal effect of increased billing frequency on consumer behavior i exploit a natural experiment in which residential water customers switched exogenously from bimonthly to monthly billing customers increase consumption by 3 5 5 in response to more frequent information this result is reconciled in models of price and quantity uncertainty where increases in billing frequency reduce the distortion in consumer perceptions using treatment effects as sufficient statistics i calculate consumer welfare gains equivalent to 0 5 1 of annual water expenditures heterogeneous treatment effects suggest increases in outdoor water use

work incentives and the food stamp program abstract labor supply theory makes strong predictions about how the introduction or expansion of a social welfare program impacts work effort although there is a large literature on the work incentive effects of afdc and the eitc relatively little is known about the work incentive effects of the food stamp program and none of the existing literature is based on quasi experimental methods we use the cross county introduction of the program in the 1960s and 1970s to estimate the impact of the program on the extensive and intensive margins of labor supply earnings and family cash income consistent with theory we find reductions in employment and hours worked when food stamps are introduced the reductions are concentrated among families headed by single woman

reference dependent consumption plans we develop a rational dynamic model in which people are loss averse over changes in beliefs about present and future consumption because changes in wealth are news about future consumption preferences over money are reference dependent if news resonates more when about imminent consump tion than when about future consumption a decision maker might to generate pleasant surprises overconsume early relative to the optimal committed plan increase immediate consumption following surprise wealth increases and delay decreasing consumption following surprise losses since higher wealth mitigates the effect of bad news people exhibit an unambiguous first order precautionary savings motive

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
