does working from home work evidence from a chinese experiment about 10 of us employees now regularly work from home wfh but there are concerns this can lead to shirking from home we report the results of a wfh experiment at ctrip a 16 000 employee nasdaq listed chinese travel agency call center employees who volunteered to wfh were randomly assigned to work from home or in the office for 9 months home working led to a 13 performance increase of which about 9 was from working more minutes per shift fewer breaks and sick days and 4 from more calls per minute attributed to a quieter working environment home workers also reported improved work satisfaction and experienced less turnover but their promotion rate conditional on performance fell due to the success of the experiment ctrip rolled out the option to wfh to the whole firm and allowed the experimental employees to re select between the home or office interestingly over half of them switched which led to the gains from wfh almost doubling to 22 this highlights the benefits of learning and selection effects when adopting modern management practices like wfh

giving in to social pressure in light of recent evidence we develop a theory of charitable giving in which donors feel social pressure from a direct solicitation we show that equilibrium donations are concentrated around a social norm donors below the norm increase giving while those above the norm reduce it despite a higher level of the public good relatively poor and or low altruism givers fare worse under social pressure and would avoid the solicitor at a cost aggregate donor welfare improves to the extent that the added social motive alleviates the underprovision of the public good however overprovision may result our theory therefore predicts a light handed regulation for charitable solicitations which is consistent with their exemption from the popular do not call list in the u s we further show that contrary to pure altruism a more equal income distribution may produce more of the public good in fundraising campaigns where a social norm is not apparent one may emerge endogenously if donors are not too heterogeneous in fact multiple social norms may form which offers a focal point argument for suggested donations

the impact of private and public feedback on worker performance evidence from the lab previous empirical studies have demonstrated the positive incentive effects of private performance feedback as well as public recognition on work performance in our laboratory experiments we directly compare these two feedback schemes moreover we compare their incentive effects across two real effort tasks that differ in regard to how interesting the subjects perceive working on them we find that both feedback schemes lead to performance increases compared to the tasks respective control treatments in particular subjects ability and a positive interim feedback enhance performance competitive preferences significantly affect performance only in the less enjoyable and challenging task jel c9 j3 m1

the effects of human resource management practices on productivity a study of steel finishing lines the authors investigate the productivity effects of innovative employment practices using data from a sample of thirty six homogeneous steel production lines owned by seventeen companies the productivity regressions demonstrate that lines using a set of innovative work practices which include incentive pay teams flexible job assignments employment security and training achieve substantially higher levels of productivity than do lines with the more traditional approach which includes narrow job definitions strict work rules and hourly pay with close supervision their results are consistent with recent theoretical models which stress the importance of complementarities among work practices

taking the high road compliance with commuter tax allowances and the role of evasion spillovers abstract this paper provides evidence of evasion in the context of a widely used commuter tax allowance and explores evasion spillovers as a determinant of the individual compliance decision for this purpose we exploit discontinuities in the commuter allowance scheme and employ a research design resting on a large panel of individual tax returns we find that around 30 of all allowance claims are overstated and consistent with deliberate tax evasion we observe sharp reactions of taxpayers to thresholds where the allowance discretely jumps to a higher amount further we use variation in job changes to uncover spillover effects from the work environment on the individual compliance decision these effects appear to be asymmetric job changers moving to companies with a higher fraction of cheaters increase their cheating in contrast movers to companies with a lower fraction of cheaters tend not to alter their reporting behavior we provide suggestive evidence that the spillover has more to do with an information environment but can ultimately not reject other behavioral explanations such as asymmetric persistence of norms

race specific urban wage premia and the black white wage gap abstract we establish a novel empirical fact about the black white wage gap looking both across and within metropolitan areas increasing city size or employment density is associated with a larger black white wage gap the estimated effects represent between 9 and 18 of recent estimates of the black white wage gap using a variety of techniques we demonstrate that our within city relationship is unlikely to be driven by racial differences in unobserved ability finally we present evidence suggestive of a role for race specific networks in explaining these differences in the black white wage gap

on the economic architecture of the workplace repercussions of social comparisons among heterogeneous workers we analyze the impact on a firm s profits and optimal wage rates and on the distribution of workers earnings when workers compare their earnings with those of coworkers we consider a low productivity worker who receives lower wage earnings than a high productivity worker when the low productivity worker derives dis utility not only from his own effort but also from comparing his earnings with those of the high productivity worker his response to the sensing of relative deprivation is to increase the optimal level of effort consequently the firm s profits are higher its wage rates remain unchanged and the distribution of earnings is compressed

peer pressure and partnerships partnerships and profit sharing are often claimed to motivate workers by giving them a share of the pie but in organizations of any significant size the free rider effects would seem to choke off

productivity spillovers in team production evidence from professional basketball we estimate a model where workers are heterogeneous both in their own productivity and in their ability to facilitate the productivity of others we use data from professional basketball to measure the importance of peers in productivity because we have clear measures of output and members of a worker s group change on a regular basis our empirical results highlight that productivity spillovers play an important role in team production despite this we find that worker compensation is largely determined by own productivity with little weight given to productivity spillovers

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

fair wages and effort provision combining evidence from a choice experiment and a field experiment the presence of workers who reciprocate higher wages with greater effort can have important consequences for firms and labor markets knowledge about the extent and determinants of reciprocal effort choices is however incomplete we investigate the role of fairness perceptions and social preferences in a field experiment in which workers were hired for a one time job we show that workers who perceive being underpaid at the base wage increase their performance if the hourly wage increases whereas those who feel adequately paid or overpaid at the base wage do not change their performance moreover we find that only the workers who display reciprocity in a choice experiment show reciprocal effort responses in the field the workers who lack reciprocity in the choice experiment do not respond to the wage increase even if they feel underpaid at the base wage our findings suggest that fairness perceptions and social preferences are key in workers performance response to wage increases in our study the wage increase affects effort mainly through the removal of perceived unfairness i e the elimination of negative reciprocity toward the firm rather than positive reciprocity these results are the first direct evidence of the fair wage effort hypothesis in the field and also help interpret previous contradictory findings in the literature data as supplemental material are available at http dx doi org 10 1287 mnsc 2014 1970 this paper was accepted by uri gneezy behavioral economics

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

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

a multinomial choice model of neighborhood effects this paper provides a model of individual decisionmaking in the presence of neighborhood effects by neighborhood effects we refer to interdependencies between individual decisions and the decisions and characteristics of others within a common neighborhood as such neighborhood effects are forms of social interactions in fact the terms would seem to be interchangeable in many contexts within economics there has developed an increasing recognition that neighborhood effects play a possibly major role in explaining a range of individual behaviors rich empirical and theoretical literatures have developed a failing of much of this work is the absence of strong connections between theory and empirics this paper addresses this limitation by providing a model of multinomial choice with neighborhood effects the model represents a generalization of the binary choice model of william brock and steven durlauf 2001a b the model is econometrically implementable and so has the potential of allowing for structural estimation of neighborhood effects section i outlines a basic choice model with neighborhood effects section ii specializes the structure using a multinomial logit framework section iii considers econometric implementation section iv discusses some limitations of the framework and proposes some research directions proofs of all theorems may be found in brock and durlauf 2001c

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

skilled immigration and innovation evidence from enrolment fluctuations in us doctoral programmes we study the contribution of foreign science and engineering talent to the creation of new knowledge in the u s economy using panel data on 2300 science and engineering s e departments at 100 large american universities from 1973 to 1998 we use macroeconomic shocks and policy changes in source countries that differentially affect enrollments across fields and universities to isolate exogenous variation in the supply of students at specific departments both foreign and domestic graduate students are central inputs into knowledge creation and the marginal foreign student contributes more to the production of scientific publications and citations a 10 decrease in the foreign share of doctoral students lowers s e research output at u s universities by 5 6 a theoretical model of university admissions and scholarships helps us infer the productivity effects of student quality and econometric results indicate that any visa restrictions limiting entry of highquality foreign students is most costly for u s innovation increased diversity appears to be the primary mechanism by which foreign students improve research outcomes the impact of more restrictive immigration policies depends on how they affect the quality margin and diversity of incoming foreigners

how does peer pressure affect educational investments when effort is observable to peers students may try to avoid social penalties by conforming to prevailing norms to test this hypothesis we first consider a natural experiment that introduced a performance leaderboard into computer based high school courses the result was a 24 percent performance decline the decline appears to be driven by a desire to avoid the leaderboard top performing students prior to the change those most at risk of appearing on the leaderboard had a 40 percent performance decline while poor performing students improved slightly we next consider a field experiment that offered students complimentary access to an online sat preparatory course sign up forms differed randomly across students only in whether they said the decision would be kept private from classmates in nonhonors classes sign up was 11 percentage points lower when decisions were public rather than private honors class sign up was unaffected for students taking honors and nonhonors classes the response depended on which peers they were with at the time of the offer and thus to whom their decision would be revealed when offered the course in a nonhonors class where peer sign up rates are low they were 15 percentage points less likely to sign up if the decision was public but when offered the course in an honors class where peer sign up rates are high they were 8 percentage points more likely to sign up if the decision was public thus students are highly responsive to their peers are the prevailing norm when they make decisions

peer effects and incentives in a multi agent setting individuals often compare own performance with that of their peers these comparisons influence agents incentives and lead to a noncooperative game even if the agents have to complete independent tasks i show that depending on the interplay of the peer effects agents efforts are either strategic complements or strategic substitutes but the informativeness principle always applies i solve for the optimal monetary incentives that complement the peer effects in case of limited liability the principal may prefer to implement inefficiently large efforts although agents earn positive rents that increase in the respective agent s effort level

peer effects in the workplace existing evidence on peer effects in the productivity of coworkers stems from either laboratory experiments or real world studies referring to a specific firm or occupation in this paper we aim at providing more generalizable results by investigating a large local labor market with a focus on peer effects in wages rather than productivity our estimation strategy which links the average permanent productivity of workers peers to their wages circumvents the reflection problem and accounts for endogenous sorting of workers into peer groups and firms on average over all occupations and in the type of high skilled occupations investigated in studies on knowledge spillover we find only small peer effects in wages in the type of low skilled occupations analyzed in extant studies on social pressure in contrast we find larger peer effects about one half the size of those identified in similar studies on productivity

who gets the job referral evidence from a social networks experiment we use recruitment into a laboratory experiment in kolkata india to analyze how job networks select individuals for employment opportunities we present evidence that individuals face a tradeoff between choosing the most qualified individual for the job and the individual who is ideal from the perspective of their social network the experiment allows randomly selected subjects to refer members of their social networks to subsequent rounds of the experiment and varies the incentive schemes offered to these participants we find that when faced with performance pay individuals are more likely to refer co workers and less likely to refer family members high ability participants who are offered performance pay recruit referrals who perform significantly better on a cognitive ability task and also prove to be more reliable as evidenced by their choices in the trust game and performance on an effort task

does whom you know matter unraveling the influence of peers network attributes on academic performance this paper examines how students network size distance prestige and connections to influential individuals impact academic performance larger and closer networks facilitate information exchange but may also increase distractions that decrease productivity we resolve this ambiguity using administrative data from a business school that features random assignment of students to multiple overlapping sets of peers allowing us to calculate degree closeness eigenvector and katz bonacich centrality for each node we find that increasing closeness centrality within the network negatively affects student performance measured by grade point average suggesting that synergy reduction and information processing costs outweigh benefits from greater information access jel i23 l14 l23

how does working in a finance profession affect mortgage delinquency abstract this paper uses a dataset from a leading american subprime lender which contains detailed information on borrower and loan characteristics we find that financial professionals are less likely to become delinquent this effect cannot be explained by borrower characteristics such as income education loan terms property characteristics geographic effects or strategic default we also find variation in the effect of working in a financial profession across borrowers of different ages and income levels we discuss explanations for these results

peer effects in financial decision making abstract peer effects might play an important role in complex financial decisions because many consumers lack experience with them and the costs of thinking through such decisions can be very high we study peer effects in retirement savings life insurance purchase and two charitable giving programs in a military setting with plausibly exogenous assignment of individuals to social groups peers defined broadly as social groups which may include members of different ranks appear to play an important role in the charitable giving programs but not in the other outcomes we assess a number of potential reasons for the disparate findings and provide suggestive evidence that the observability of individuals choices is key

moving to opportunity in boston early results of a randomized mobility experiment this paper examines the short run impacts of a change in residential neighborhood on the well being of low income families using evidence from a program in which eligibility for a housing voucher was determined by random lottery we examine the experiences of households at the boston site of moving to opportunity mto a demonstration program in five cities families in high poverty public housing projects applied to mto and were assigned by lottery to one of three groups experimental offered mobility counseling and a section 8 subsidy valid only in a census tract with a poverty rate of less than 10 percent section 8 comparison offered a geographically unrestricted section 8 subsidy or control offered no new assistance but continued to be eligible for public housing our quantitative analyses of program impacts uses data on 540 families from a baseline survey at program enrollment a follow up survey administered l to 3 5 years after random assignment and state administrative data on earnings and welfare receipt 48 percent of the experimental group and 62 percent of the section 8 comparison group moved through the mto program one to three years after program entry families in both treatment groups were more likely to be residing in neighborhoods with low poverty rates and high education levels than were families in the control group however while members of the experimental group were much more likely to be residing in suburban communities than were those in the section 8 group the lower program take up rate among the experimental group resulted in more families remaining in the most distressed communities households in both treatment groups experienced improvements in multiple measures of well being relative to the control group including increased safety improved health among household heads and fewer behavior problems among boys experimental group children were also less likely to be a victim of a personal crime to be injured or to experience an asthma attack there are no significant impacts of either mto treatment on the employment earnings or welfare receipt of household heads in the first three years after random assignment

the long run consequences of living in a poor neighborhood author s oreopoulos philip abstract many social scientists presume that the quality of the neigborhood to which children are exposed affects a variety of long run social outcomes i examine the effect on the long run labor market outcomes of adults who were assigned when young to substantially different public housing projects in toronto administrative data are matched to public housing addresses to track children from the program for over 15 years the main finding is that neighborhood quality plays little role in determining a youth s adult earnings education attainment or welfare participation but does affect exposure to crime while living in contrasting housing projects cannot explain large variances in labor market outcomes family differences as measured by sibling outcome correlations account for up to 30 percent of the total variance in the data

social image concerns and welfare take up abstract using a laboratory experiment we present first evidence that social image concerns causally reduce the take up of an individually beneficial transfer our design manipulates the informativeness of the take up decision by varying whether transfer eligibility is based on ability or luck and how the transfer is financed we find that subjects avoid the inference both of being low skilled ability stigma and of being willing to live off others free rider stigma using a placebo treatment we exclude other explanations for the observed stigma effects although stigma reduces take up elicitation of political preferences reveals that only a minority of taxpayers vote for the public transfer

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

optimal design of social comparison effects setting reference groups and reference points in this paper we study how social planners should exploit social comparisons to pursue their objectives we consider two modes of social comparison referred to as behind averse and ahead seeking behaviors depending on whether individuals experience a utility loss from underperforming or a utility gain from overperforming relative to their peers modeling social comparison as a game between players we find that ahead seeking behavior leads to output polarization whereas behind averse behavior leads to output clustering a social planner can mitigate these effects in two ways i by providing the full reference distribution of outputs instead of an aggregate reference point based on the average output and ii by assigning players into uniform rather than diverse reference groups social planners may thus need to tailor the reference structure to the predominant mode of social comparison and their objective a performance focused social planner may set the reference structure so as to maximize the output of either the top or the bottom player depending on whether she puts greater marginal weight to larger or smaller outputs when the social planner also cares about utility she faces a dilemma because performance optimization may not be aligned with utility maximization inevitably the social planner will have to confront equity issues because better performance may not reflect greater effort or greater ability this paper was accepted by serguei netessine operations management

gender and peer effects on performance in social networks we investigate whether peer effects at work differ by gender and whether gender differences in peer effects if any depend on work organization we develop a social network model with gender heterogeneity that we test in a real effort laboratory experiment we compare sequential networks in which information flows from peers to the worker and simultaneous networks where it disseminates bi directionally we identify strong gender differences as females disregard their peers performance in simultaneous networks while males are influenced by peers in both networks females may perceive the environment in simultaneous networks as being more competitive than in sequential networks

surviving andersonville the benefits of social networks in pow camps twenty seven percent of the union army prisoners captured july 1863 or later died in captivity at andersonville the death rate may have been as high as 40 percent how did men survive such horrific conditions using two independent datasets we find that friends had a statistically significant positive effect on survival probabilities and that the closer the ties between friends as measured by such identifiers as ethnicity kinship and the same hometown the bigger was the impact of friends on survival probabilities jel n41 z13

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

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

ethical spillovers in firms evidence from vehicle emissions testing in this paper we explore how organizations influence the unethical behavior of their employees using a unique data set of over three million vehicle emissions tests we find strong evidence of ethical spillovers from firms to individuals when inspectors work across different organizations they adjust the rate at which they pass vehicles to the norms of those with whom they work these spillovers are strongest at large facilities and corporate chains and weakest for the large volume inspectors these results are consistent with the economics literature on productivity spillovers from organizations and peers and suggest that managers can influence the ethics of employee behavior through both formal norms and incentives the results also suggest that employees have persistent ethics that limit the magnitude of this influence these results imply that if ethical conformity is important to the financial and legal health of the organization managers must be vigilant in their hiring training and monitoring to ensure that employee behavior is consistent with firm objectives

work environment and individual background explaining regional shirking differentials in a large italian firm the prevalence of shirking within a large italian bank appears to be characterized by significant regional differentials in particular absenteeism and misconduct episodes are substantially more prevalent in the south we consider a number of potential explanations for this fact different individual backgrounds group interaction effects sorting of workers across regions differences in local attributes different hiring policies and discrimination against southern workers our analysis suggests that individual backgrounds group interaction effects and sorting effects contribute to explaining the north south shirking differential none of the other explanations appears to be of first order importance i introduction whether individual behavior is determined by group interactions or by individual background is undoubtedly a fundamental question for the social sciences this question presented itself forcefully when we stumbled onto the following piece of evidence there appear to be significant regional differentials in the prevalence of shirking among the employees of a large italian bank in particular absenteeism and misconduct episodes are considerably more frequent in the southern branches of the bank in this paper we examine several potential explanations for this fact first individual preferences for shirking versus working may differ according to one s region of hirth we will refer to this hj othesis as one of different individual hackgrounds the second possibility is one of locational sorting low shirking types may tend to migrate to the north high shirking types may tend to migrate to the south or hoth third the northern and southern

worker absence and productivity evidence from teaching a significant amount of work time is lost each year due to worker absence but evidence on the productivity losses from absenteeism remains scant due to difficulties with identification we use uniquely detailed data on the timing duration and cause of absences among teachers to address many of the potential biases from the endogeneity of worker absence our analysis indicates that worker absences have large negative impacts the expected loss in daily productivity from employing a temporary substitute is on par with replacing a regular worker of average productivity with one at the 10th 20th percentile of productivity

workplace productivity and bonus preferences why do men with low productivity prefer individual pay this paper examines the relationship between workers productivity and preferred bonus scheme the data are from a company where agents work in teams and receive a bonus that depends on individual and team performance standard agency theory predicts that workers with productivity below the team average prefer a team bonus while high productivity agents prefer an individual bonus risk aversion may temper the taste for individual pay this model predicts the observed relationship between productivity and bonus preferences very well there is however one pattern that it cannot explain many low performers especially men prefer individual bonuses

social interaction at work abstract stock market investment decisions of individuals are positively correlated with those of coworkers sorting of unobservably similar individuals to the same workplaces is unlikely to explain this pattern as evidenced by the investment behavior of individuals who move between plants purchases made under stronger coworker purchase activity are not associated with higher returns moreover social interaction appears to drive the purchase of within industry stocks overall we find a strong influence of coworkers on investment choices but not an influence that improves the quality of investment decisions

discrete choice with social interactions this paper provides an analysis of aggregate behavioural outcomes when individual utility exhibits social interaction effects we study generalized logistic models of individual choice which incorporate terms reflecting the desire of individuals to conform to the behaviour of others in an environment of noncooperative decisionmaking laws of large numbers are generated in such environments multiplicity of equilibria in these models which are equivalent to the existence of multiple self consistent means for average choice behaviour will exist when the social interactions exceed a particular threshold local stability of these multiple equilibria is also studied the properties of the noncooperative economy are contrasted with the properties of an economy in which a social planner determines the set of individual choices finally a likelihood function based on the theoretical model is given and conditions for the econometric identifiability of the model are established

disappointment aversion and social comparisons in a real effort competition we present an experiment to investigate the source of disappointment aversion in a sequential real effort competition specifically we study the contribution of social comparison effects to the disappointment aversion previously identified in a two person real effort competition gill d and v prowse a structural analysis of disappointment aversion in a real effort competition american economic review 102 2012 469 503 to do this we compare social and asocial versions of the gill and prowse experiment where the latter treatment removes the scope for social comparisons if disappointment aversion simply reflects an asymmetric evaluation of losses and gains we would expect it to survive in our asocial treatment alternatively if losing to or winning against another person affects the evaluation of losses gains as we show would be theoretically the case under asymmetric inequality aversion we would expect treatment differences we find behavior in social and asocial treatments to be similar suggesting that social comparisons have little impact in this setting unlike in gill and prowse we do not find evidence of disappointment aversion jel c91 d12 d81 d84

consumption network effects in this paper we study the relevance and mechanics of consumption network effects we use long panel data on the entire danish population to construct a measure of consumption based on administrative tax records and define the peer groups in terms of workplace occupation education and age we then apply an iv strategy and fixed effect models to recover the effects our instruments arise naturally from the network structure and firms shocks the estimated effects are statistically significant and relevant for policies as they generate non negligible multiplier effects further the results are consistent with a keeping up model

the economic consequences of brain drain of the best and brightest microeconomic evidence from five countries this article presents results of innovative surveys that tracked academic high achievers from five countries to wherever they moved in the world to directly measure at the micro level the channels through which high skilled emigration affects sending countries there are high levels of emigration and of return and the income gains to the best and brightest from migrating are an order of magnitude greater than any other effect most high skilled migrants from poorer countries remit but involvement in trade and foreign direct investment is rare fiscal costs vary widely but are much less than the benefits to the migrants themselves two narratives drive discussions of the development impact of high skilled migration the first is the idea of a brain drain whereby the departure of doctors teachers engineers scientists and other highly skilled workers decimates the human capital and fiscal revenues of sending countries bhagwati and hamada 1974 such fears lead to calls for policies to restrict the flow of highly skilled workers such as demands that developed countries stop recruiting doctors from developing nations and efforts by developing nations to restrict the ease of their highly skilled individuals migrating 1 contrasting with this is the view of a highly educated diaspora as a potent force for developing the local economy through remittances trade foreign direct investment fdi and knowledge transfers with the experience of india and china in setting up technology firms as a result of diaspora working in silicon valley a prominent example saxenian 2002 economists have also emphasised that the possibility of migrating may spur human capital accumulation potentially leading to a net increase in the education levels of those in the home country 2

peer effects in program participation the influence of peers could play an important role in the take up of social programs however estimating peer effects has proven challenging given the problems of reflection correlated unobservables and endogenous group membership we overcome these identification issues in the context of paid paternity leave in norway using a regression discontinuity design our approach differs from existing literature which attempts to measure peer effects by exploiting random assignment to peer groups in contrast we study peer effects in naturally occurring peer groups but exploit random variation in the price of a social program for a subset of individuals fathers of children born after april 1 1993 in norway were eligible for one month of governmental paid paternity leave while fathers of children born before this cutoff were not there is a sharp increase in fathers taking paternity leave immediately after the reform with take up rising from 3 to 35 while this quasirandom variation changed the cost of paternity leave for some fathers and not others it did not directly affect the cost for the father s coworkers or brothers therefore any effect on the brother or the coworker can be attributed to the influence of the peer father in their network our key findings on peer effects are four fold first we find strong evidence for substantial peer effects of program participation in both workplace and family networks coworkers and brothers are 11 and 15 percentage points respectively more likely to take paternity leave if their peer father was induced to take up leave by the reform second the most likely mechanism is information transmission about costs and benefits including increased knowledge of how an employer will react third there is essential heterogeneity in the size of the peer effect depending on the strength of ties between peers highlighting the importance of duration intensity and frequency of social interactions fourth the estimated peer effect gets amplified over time with each subsequent birth exhibiting a snowball effect as the original peer father s influence cascades through a firm our findings demonstrate that peer effects can lead to long run equilibrium participation rates which are substantially higher than would otherwise be expected

the effects of training on own and co worker productivity evidence from a field experiment this article identifies the effects of work related training on worker productivity by exploiting a field experiment that randomly assigns workers to treatment and control groups combined with data on worker performance before and after training we find that participation in the training programme leads to a 10 increase in performance moreover we provide experimental evidence for externalities from training an increase of 10 percentage points in the share of treated peers improves a worker s performance by 0 51 furthermore we find that the performance increase is not due to lower quality provided by the worker

do peers influence occupational preferences evidence from randomly assigned peer groups at west point abstract there is substantial variation across occupations in outcomes such as earnings job satisfaction and health yet little is known about how occupational preferences are shaped and evolve this paper assesses a channel that may influence occupational preferences peer effects by exploiting unique institutional features and a natural experiment at west point to document the way students i e cadets occupational preferences evolve and to test for peer effects after graduation cadets must enter the u s army as an officer in one of 16 occupational branches and are required to rank order their preferences for the branches repeatedly over four years west point randomly assigns cadets to social groups both at broad company and narrow roommate levels we leverage the timing of the randomization and preference elicitations to test for peer effects at the company roommate and older peer levels with the possible exception of the first few weeks of exposure we find little evidence of peer effects we also use a survey of cadets to explore mechanisms and find evidence that peer information may not be credible in this case but rather cadets rely on mentors and job characteristics when making this decision

clean evidence on peer effects we study subjects who were asked to fill letters into envelopes with a remuneration independent of output in the pair treatment two subjects worked at the same time in the same room and peer effects were possible in the single treatment subjects worked alone and peer effects were ruled out we find evidence of peer effects in the pair treatment because the standard deviations of output are smaller within pairs than between pairs moreover average output is higher in the pair treatment thus peer effects raise productivity finally low productivity workers are the most sensitive to the behavior of peers

the effect of peer observation on consumption choices evidence from a lab in field experiment abstractwe investigate the impact of peer observation on consumption decisions using a lab in field experiment respondents make consumption decisions either alone or under peer observation we fin

modeling the demand for alcoholic beverages and advertising specifications in this paper the demand for beer wine spirits and soft drinks in ontario is modeled in two parts an equation is specified to endogenize group expenditures and a demand system is set up to allocate budgeted group expenditures across types of beverages advertising is allowed to influence both the level of group expenditures and its allocation three popular advertising specifications are compared using the j test and the likelihood dominance criterion even though all three specifications fitted well according to standard criteria the calculated expenditure price and advertising elasticities were sensitive to the manner with which advertising is specified this clearly highlights the need to rely on a sound criterion to identify a dominant specification from the identified dominant specification we found that advertising has very subtle effects on expenditures on alcoholic beverages group and individual beverages thus advertising is not effective in enlarging markets and this suggests that firms especially breweries use advertising to compete in zero sum market share games from a public policy perspective our results are comforting but future research should investigate whether the neutral effect of advertising on aggregated expenditures hide substantial offsetting changes in the drinking habits of individuals 2000 elsevier science b v all rights reserved

accounting for complementary skill sets evaluating individual marginal value to a team in the national basketball association identifying an individual worker s contribution to firm production can be difficult in a team setting where spillovers in labor productivity exist among team members this paper studies a model of labor productivity where workers have heterogeneous abilities and can differently affect the productivity of their fellow teammates applying the model to the setting of the national basketball association nba i can identify the marginal value that a basketball player brings to a particular team lineup both through his own individual contributions and his complementary contribution to teammates productivity estimates from the model imply that teammates have a significant impact on individual player productivity and that taking into account spillovers across teammates is important to assessing both overall team productivity and an individual player s contribution to team productivity i then evaluate whether player complementarities are valued in the nba labor market in terms of higher salaries and find that they are undervalued and that players are instead paid mainly for their individual offensive production this creates an asymmetry between player incentives and the team objective to assess the size of this inefficiency the top trading cycle algorithm of shapley and scarf 1974 is used to identify a pareto optimal matching between players and teams that accounts for the complementarities between heterogeneous players skill sets jel j30 l25 l83 m51

what is a peer the role of network definitions in estimation of endogenous peer effects we employ a standard identification strategy from the peer effects literature to investigate the importance of network definitions in estimation of endogenous peer effects we use detailed information on friends in the national longitudinal study of adolescent health survey add health to construct two network definitions that are less ad hoc than the school grade cohorts commonly used in the educational peer effects literature we demonstrate that accurate definitions of the network seriously impact estimation of peer effects in particular we show that peer effects estimates on educational achievement smoking and drinking are substantially larger with our more detailed measures than with the school grade cohorts these results highlight the need to further understand how friendships form in order to fully understand implications for policy that alters the peer group mix at the classroom or cohort level

network effects and welfare cultures we empirically examine the role of social networks in welfare participation using data on language spoken at home to better infer networks within an area our empirical strategy asks whether being surrounded by others who speak the same language increases welfare use more for those from high welfare using language groups this methodology allows us to include local area and language group fixed effects and to control for the direct effect of being surrounded by one s language group these controls eliminate many of the problems in previous studies the results strongly confirm the importance of networks in welfare participation

peer effects among swimmers we develop a novel identification strategy and examine various aspects of peer effects using swimming data we find that the performance of adjacent competitors positively influences swimmers performances in particular swimmers are influenced by slower lane peers suggesting that being chased improves one s performance we use absenteeism data to directly compare the performances of swimmers with and without peers we have found that swimmers swim faster with peers swimming behind them than when swimming alone but that they swim slower with peers swimming ahead finally we find that observability is a key determinant of peer effects by comparing freestyle and backstroke competitions

interactions between workers and the technology of production evidence from professional baseball this paper examines how the effort choices of workers within the same firm interact with each other in contrast to the existing literature we show that workers can affect the productivity of their co workers based on income maximization considerations rather than relying on behavioral considerations such as peer pressure social norms and shame theoretically we show that a worker s effort has a positive effect on the effort of co workers if they are complements in production and a negative effect if they are substitutes the theory is tested using panel data on the performance of baseball players from 1970 to 2003 the empirical analysis shows that a player s batting average significantly increases with the batting performance of his peers but decreases with the quality of the team s pitching furthermore a pitcher s performance increases with the pitching quality of his teammates but is unaffected by the batting output of the team these results are inconsistent with behavioral explanations which predict that shirking by any kind of worker will increase shirking by all fellow workers the results are consistent with the idea that the effort choices of workers interact in ways that are dependent on the technology of production these findings are robust to controlling for individual fixed effects and to using changes in the composition of one s co workers in order to produce exogenous variation in the performance of one s peers

does firm investment respond to peers investment we study whether how and why the investment of a firm depends on the investment of other firms in the same product market using an instrumental variable based on the presence of local knowledge

random interactions in the chamber legislators behavior and political distance abstract i investigate the role of social interaction among members of parliament mps and the impact of such interaction on the political distance between parties using the random allocation of seats in the icelandic parliament i find that mp s voting and speech behaviors are affected by the behavior of legislators seated nearby i also show that greater random exposure to mps from different parties ultimately reduces the political distance between parties similar evidence is found using historical data for the u s house of representatives by exploiting the introduction of a lottery mechanism to determine desk assignments in 1845 i argue that random seating arrangements could constitute a low cost way of reducing differences within the political arena

the social multiplier aggregate data is often used to make inferences about individual level behavior if there are social interactions in which one person s actions influence his neighbor s incentives or information then these inferences are inappropriate the presence of positive social interactions or strategic complementarities implies the existence of a social multiplier where aggregate relationships will overstate individual elasticities we present a brief model and then estimate the size of the social multiplier in three areas the impact of education on wages the impact of demographics on crime and group membership among dartmouth roommates in these contexts there is a significant social multiplier jel ho jo co

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

how accurate are surveyed preferences for public policies evidence from a unique institutional setup opinion polls and other surveys are used to capture public sentiments on a variety of issues if citizens are unwilling to reveal certain policy preferences to others surveys may fail to characterize population preferences accurately the innovation of this paper is to use unique data to measure survey biases for a broad range of policies i combine data on 184 referenda held in switzerland between 1987 and 2007 with postballot surveys that ask how the citizens voted for each proposal the dierence between stated preferences in the survey and revealed preferences at the ballot box provides a direct measure of survey bias i nd that these biases vary by policy areas with the largest occurring in

are workers willing to pay to join a better team using data from the major league baseball free agent market this study is the first to show that the productivity expected of the team a worker will join produces a significant negative compensating wage differential the younger workers in the sample drive this result trading 25 of their wages to join teams with an expected productivity one standard deviation higher this investment can be recouped if a reasonable increase in human capital occurs these results are robust to contract length wage simultaneity and indicate that investment in human capital motivates the observed tradeoff suggesting a new pathway through which human capital accumulation can affect wages reliable measures of workers own past productivity and the productivity expected of a worker s future team provide key advantages to identifying these effects jel j31 j24 m54

it s not your peers and it s not your friends some progress toward understanding the educational peer effect mechanism abstract using a new administrative panel data set from the university of maryland this paper explores conventional peer effects and the effects of socially proximate peers at a large public university where some students are randomly assigned to housing results show that there is little evidence of robust residential peer effects on undergraduate performance the impact of socially proximate peers characteristics on student achievement is then examined using an instrumental variables technique results indicate that social friends do not impact performance more than randomized peers the paper casts doubt on the notion that social tie formation is the route to peer effects and urges caution in the continued pursuit of peer effects in education without substantial empirical or theoretical innovation

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

do monetary incentives undermine performance on intrinsically enjoyable tasks a field test economists have long been intrigued by an influential literature in psychology positing that monetary pay lowers performance on enjoyable tasks by crowding out agents intrinsic interest in them b

the importance of relative performance feedback information evidence from a natural experiment using high school students we study the effect of providing relative performance feedback information on performance under piece rate incentives a natural experiment that took place in a high school offers an unusual opportunity to test this effect in a real effort setting for one year only students received information that allowed them to know whether they were above below the class average as well as the distance from this average we exploit a rich panel data set and find that the provision of this information led to an increase of 5 in students grades moreover the effect was significant for the whole distribution however once the information was removed the effect disappeared to rule out the concern that the effect may be driven by teachers within the school we verify our results using national level exams externally graded for the same students and the effect remains

peer effects in science evidence from the dismissal of scientists in nazi germany this paper analyses peer effects among university scientists specifically it investigates whether the quality and the number of peers affect the productivity of researchers in physics chemistry and mathematics the usual endogeneity problems related to estimating peer effects are addressed by using the dismissal of scientists by the nazi government in 1933 as a source of exogenous variation in the peer group of scientists staying in germany to investigate localized peer effects i construct a new panel data set covering the universe of scientists at the german universities from 1925 to 1938 from historical sources i find no evidence for peer effects at the local level even very high quality scientists do not affect the productivity of their local peers

why do we lie a practical guide to the dishonesty literature over the last decade a massive body of research has been devoted to uncovering human dishonesty in the present paper we review more than a hundred papers from this literature and provide a comprehensive overview by first listing the existing theoretical frameworks and then covering the common empirical approaches synthesizing the demographic and personal characteristics of those who cheat identifying the behavioural mechanisms found that affect dishonesty and finally we finish by discussing how the empirical evidence fit theory overall the review concludes that many people behave dishonestly but also that it is a highly malleable behavior sensitive to elements such as decision contexts behaviour of others state of mind and depletion the review can be used as an overview of the dishonesty literature or as a guide or work of reference for selected topics of interest

looking after number two competition cooperation and workplace interaction abstract we look for cooperation in a real world setting in which optometrists absent less frequently in two chair than one chair offices because of the externality such behavior imposes on their co worker we motivate our empirical analysis by developing a model of worker interdependence in which two workers can either compete or cooperate we show that relative to a single worker working in isolation competition unequivocally increases absence whilst cooperation may increase or decrease absence our empirical analysis of a unique data set finds explicit support for cooperative behavior

dynamic pricing for subscription services this paper investigates the use of pricing schemes in subscription services that consist of various combinations of activation subscription and cancellation fees when customers exclusively consider what is directly perceivable the activation fee starts low and increases as the network grows penetration strategy whereas the cancellation fee starts high and decreases as the network grows skimming strategy the activation and cancellation fees take various other forms otherwise the subscription fee remains low at the early stages and increases only when a reasonable number of subscribers is secured finally the authors discuss the theoretical and managerial implications of their findings

within firm human capital externalities in tunisia this case study exploits matched firm employee tunisian data in order to underline the role played by within firm human capital in worker remuneration the estimated returns to human capital in wage equations remain unchanged when the dummies representing firm heterogeneity are replaced in the list of regressors with three firm variables a textile industry dummy within firm mean education and firm age we find that part of what is usually considered as return to education may be due to within firm externalities

neighborhood effects on speculative behavior abstract speculative behavior plays a key role in numerous markets but little is known about its causes we test for neighborhood effects on speculative behavior using daily lottery sales data from 20 states in the u s in a sample of 160 000 retailers lottery sales in a census block increase by 0 26 on average for each 1 increase in neighboring blocks we test whether this correlation is attributable to contextual effects correlated effects or endogenous effects our analysis suggests that social interaction is an important cause of speculative behavior

can losing lead to winning individuals groups and teams who are behind their opponents in competition tend to be more likely to lose in contrast we show that through increasing motivation being slightly behind can actually increase success analysis of more than 18 000 professional basketball games illustrates that being slightly behind at halftime leads to a discontinuous increase in winning percentage teams behind by a point at halftime for example actually win more often than teams ahead by one or approximately six percentage points more often than expected this psychological effect is roughly half the size of the proverbial home team advantage analysis of more than 45 000 collegiate basketball games finds consistent though smaller results experiments corroborate the field data and generalize their findings providing direct causal evidence that being slightly behind increases effort and casting doubt on alternative explanations for the results taken together these findings illustrate that losing can sometimes lead to winning this paper was accepted by peter wakker decision analysis
