increasing dominance with no efficiency effect abstract i uncover a new force towards increasing dominance the property whereby in dynamic games the leader tends to increase his or her lead in expected terms the new effect results from the strategic choice of covariance in races i assume that players must choose not the amount of resources to spend but how to allocate those resources i show that in equilibrium the laggard chooses a less promising path in effect trading off lower expected value for lower correlation with respect to the leader this results in increasing dominance and holds true even if no joint payoff or efficiency effect is present journal of economic literature classification numbers c7 l1

smallholder market participation concepts and evidence from eastern and southern africa abstract this paper reviews the evidence on smallholder market participation with a focus on staple foodgrains i e cereals in eastern and southern africa in an effort to help better identify what interventions are most likely to break smallholders out of the semi subsistence poverty trap that appears to ensnare much of rural africa the conceptual and empirical evidence suggests that interventions aimed at facilitating smallholder organization at reducing the costs of intermarket commerce and perhaps especially at improving poorer households access to improved technologies and productive assets are central to stimulating smallholder market participation and escape from semi subsistence poverty traps macroeconomic and trade policy tools appear less useful in inducing market participation by poor smallholders in the region

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

industry classifications and return comovement a company s industry affiliation is commonly used to construct homogeneous stock groupings for portfolio risk management relative valuation and peer group comparisons a variety of industry classification systems have been adopted however creating disagreements as to companies industry assignments this analysis of the global industry classification system gics and fama french system indicates that common movement in returns and operating performance resulting from industry effects is stronger for stocks of large companies than for those of small companies also increasingly fine levels of disaggregation improve discrimination up to six digit gics codes after which the benefits tail off stock groupings based on industry exhibit stronger out of sample homogeneity than groups formed from statistical cluster analysis

assessing the impact of crop diversification on farm poverty in india summary crop diversification into high value crops hvcs can be a strategy to improve livelihood outcomes for farmers using data from a nationally representative survey we establish that households diversifying toward hvcs are less likely to be poor the biggest impact being for smallholders furthermore using continuous treatment matching we establish the relationship between degree of diversification share of area dedicated to hvc and poverty growers of hvcs need to allocate at least 50 area to hvcs to escape poverty effect of diversification on poverty is in general positive but it withers after a threshold probably because of constraints i e capital on smaller farms and labor on larger ones

labor market participation of chinese agricultural households empirical evidence from zhejiang province abstract this work is devoted to the analysis of the different labor market participation regimes of chinese farm households over the reform process in the 1980s and 1990s using household data over the period 1986 2002 from the province zhejiang we apply a multinomial logit model to empirically examine household farm and regional characteristics affecting the probability that farmers participate in one of four alternative labor market regimes as generally accepted off farm participation is the dominant form of farm households labor market participation but rural households show additionally a significant impact on rural employment mainly linked with non agricultural household business results suggest that labor market decisions are significantly related to several family farm and village characteristics in particular we find education to be a key determinant of participation furthermore results point to a higher probability of female household members to take up off farm work

racing with uncertainty and strategic interaction between competitors as the race unfolds most of the existing literature examines one or other of these features but not the two combined our aim is to see how the efforts of competitors in a race vary with the intensity of rivalry between them in our principal model whch is of a one dimensional race it is shown that the leader in the race makes greater efforts than the follower and efforts increase as the gap between competitors decreases under certain conditions the same results hold in our second related model which is of a two dimensional race

state intervention for food price stabilisation in africa can it work abstract although its arguments may have more general applicability this paper discusses the desirability and options for the stabilisation of staple food prices principally in eastern and southern africa it addresses three broad questions i why is stabilisation of food grain prices desirable ii what is technically feasible and iii can the governance and trade issues thrown up by suggested mechanisms be solved it considers a number of options for price stabilisation assessing the strengths and weaknesses of each and suggesting situations in which each may be appropriate

choice of varieties by sri lanka rice farmers comparing alternative decision models sri lanka rice farmers are faced with a choice between traditional and high yielding rice varieties three risky choice models are compared to explain producer behavior forty farmers with typically small rice areas were studied choice criteria compared were multiple two attribute utility maximization single profit attribute utility maximization and expected profit maximization expected utility maximization performed better than expected profit maximization single attribute utility maximization outperformed the more complex multiattribute utility model the importance of careful elicitation of subjective probability distributions is emphasized rice farmers appear to allocate their land between available technologies in an economically rational way

food security strategies under extremely adverse conditions the determinants of household income and consumption in rural mozambique abstract this paper uses household survey data from war torn northern mozambique to examine the factors associated with higher incomes and improved rural household food security incomes and calorie consumption were found to be low and variable in each district and both are highly correlated with land holdings the central role of land holdings is largely a result of serious market failure food market participation rates and the proportion of net buyers are lower than in other sub saharan africa ssa research purchased food as a percentage of total caloric intake and off farm income as a percentage of total income are both very low by ssa standards in short surveyed smallholders have adopted a strategy of marked reliance on farm based own production to ensure their survival it is suggested that land holdings will continue to be key determinants of household income and consumption for the foreseeable future broad based rural development efforts possibly organized around existing cotton growing enterprises may offer one way out of the poverty trap for smallholders

primaries and the new hampshire effect candidates for u s presidential elections are determined through sequential elections in single states the primaries we develop a model in which candidates can influence their winning probability in electoral districts by spending money on campaigning the equilibrium replicates several stylized facts very well campaigning is very intensive in the first district the outcome of the first election then creates an asymmetry in the candidates incentives to campaign in the next district which endogenously increases the equilibrium probability that the first winner wins in further districts on the normative side our model oers a possible explanation for the sequential organization it leads in expectation to a lower level of advertising expenditures than simultaneous elections moreover if one of the candidates is the more eective campaigner sequential elections also perform better with regard to the selection of the best candidate

buy as you need nutrition and food storage imperfections abstract in this paper we investigate whether and how a more steady supply of foodgrain in local markets impacts the nutritional status measured with body mass indexes of both children and adults in a context characterized by large seasonal fluctuations in the price and availability of foodgrain taking advantage of the random scaling up of a program of food security granaries in burkina faso we reach three conclusions first especially in remote areas where local markets are thin the program considerably dampens nutritional stress the effect is strongest among children and young children in particular for whom deficient nutrition has devastating long term consequences second we argue that it is a change in the timing of food purchases translated into a change in the timing of consumption that drives the nutritional improvement a simple two period model shows that once we account for various forms of storage costs an increase in nutrition does not necessarily require larger quantity of food purchases or even consumption our last and unexpected conclusion is that the losses associated with foodgrain storage do not stem from physical losses in household granaries but rather from inefficient seasonal bodymass fluctuations one plausible mechanism behind this particular storage imperfection rests on the households urge to consume readily available foodgrain

do tournaments have incentive effects much attention has been devoted to studying models of tournaments or situations in which an individual s payment depends only on his or her output or rank relative to that of other competitors academic interest derives from the fact that under certain sets of assumptions tournaments have desirable normative properties because of the incentive structures they provide our paper uses nonexperimental data to test whether tournaments actually elicit effort responses we focus on professional golf tournaments because information on the incentive structure prize distribution and measures of individual output players scores are both available we find strong support for the proposition that the level and structure of prizes in pga tournaments influence players performance

equilibrium play in matches binary markov games abstract we study two person extensive form games or matches in which the only possible outcomes if the game terminates are that one player or the other is declared the winner the winner of the match is determined by the winning of points in point games we call these matches binary markov games we show that if a simple monotonicity condition is satisfied then a it is a nash equilibrium of the match for the players at each point to play a nash equilibrium of the point game b it is a minimax behavior strategy in the match for a player to play minimax in each point game and c when the point games all have unique nash equilibria the only nash equilibrium of the binary markov game consists of minimax play at each point an application to tennis is provided

co2 emissions from household consumption in india between 1993 94 and 2006 07 a decomposition analysis abstract co 2 emission from anthropogenic activities is one of the major causes of global warming india being an agriculture dependent country global warming would mean monsoon instability and consequent food scarcity natural disasters and economic concerns however with proper policy interventions co 2 emissions can be controlled input output analysis has been used to estimate direct and indirect co 2 emissions by households for 1993 94 1998 99 2003 04 and 2006 07 complete decomposition analysis of the changes in co 2 emissions between 1993 94 and 2006 07 has been done to identify the causes into pollution energy intensity structure activity and population effects according to broad household consumption categories results indicate that activity structure and population effects are the main causes of increase in co 2 emission from household fuel consumption to identify the causes at the sectoral level a second decomposition has been done for changes between 2003 04 and 2006 07 to identify the causes in the next stage finally alternative energy policy options have been examined for each consumption category to reduce emissions combined strategies of technology upgradation fuel switching and market management in order to reduce co 2 emissions for sectors like batteries other non electrical machinery construction and electronic equipments including television for which all the effects are positive need to be adopted

cash crop production food price volatility and rural market integration in the third world large farmers in the third world often devote to cash crops a larger share of their land than do small farmers this paper suggests a possible explanation even in the presence of food markets third world farmers food security is best assured by food self sufficiency a model of crop portfolio choice under multivariate risk is used to show that reasonable assumptions regarding risk and preferences reproduce the observed pattern simulations further indicate that food market integration reduces the need for food self sufficiency policy implications are drawn regarding domestic trade liberalization and agricultural technology

who is behavioral cognitive ability and anomalous preferences in this paper we ask whether variation in preference anomalies is related to variation in cognitive ability evidence from a new laboratory study of chilean high school students with similar schooling backgrounds shows that small stakes risk aversion and short run discounting are less common among those with higher standardized test scores the relationship with test scores survives controls for parental education and wealth we find some evidence that elementary school gpa is predictive of preferences measured at the end of high school two laboratory interventions provide suggestive evidence of a possible causal impact of cognitive resources on expressed preferences jel j24 d14 c91

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

spatial integration transport costs and the response of local prices to policy changes in ghana abstract this paper investigates the respective roles of spatial integration and transport costs in explaining price changes in ghana we introduce a model of price formation and market integration that incorporates the price transmission process between local and central markets and also captures the implications for volatility of local prices we explore the implications of the model for the time path of price adjustments as determined directly and indirectly through the marketing sector we show that the price adjustment process in a local market is determined by the degree of interdependence between that market and the central market in which a price shock originates and estimate the intertemporal and interspatial dynamics of the price adjustment process using data from wholesale maize markets in ghana we find that reductions in local prices and local price variance following the introduction of economic reforms in 1983 can be traced to both local and central market forces but that differences in the degree of market integration have important implications for long run changes in transport costs and the evolution of prices in outlying markets

a market test for discrimination in the english professional soccer leagues this chapter proposes a market test for racial discrimination in salary setting in english league soccer over the period 1978 93 using a balanced panel of 39 clubs if there is a competitive market for the services of players the wage bill of the club will reflect their productivity and hence the performance of the club in the league discrimination can be said to exist if clubs fielding an above average proportion of black players systematically outperform clubs with a below average proportion of black players after one controls for the wage bill statistically significant evidence of discrimination in this sense is found

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

reference dependent risk attitudes we use koszegi and rabin s 2006 model of reference dependent utility and an extension of it that applies to decisions with delayed consequences to study preferences over monetary risk because our theory equates the reference point with recent probabilistic beliefs about outcomes it predicts specific ways in which the environment influences attitudes toward modest scale risk it replicates classical prospect theory including the prediction of distaste for insuring losses when exposure to risk is a surprise but implies first order risk aversion when a risk and the possibility of insuring it are anticipated a prior expectation to take on risk decreases aversion to both the anticipated and additional risk for large scale risk the model allows for standard consumption utility to dominate reference dependent gain loss utility generating nearly identical risk aversion across situations

land allocation in hyv adoption models an investigation of alternative explanations microeconomic theory provides four competing explanations for partial land allocation to new and traditional seed varieties in hyv adoption decisions input fixity portfolio selection safety first behavior and learning testing a general model that contains each as a special case suggests that they are jointly most likely to explain land allocation in the hyv adoption decisions of malawian smallholders yet when each explanation is tested to the exclusion of the others as is usually the case in the literature competing hypotheses are individually significant results suggest that employing approaches based on single explanations may lead to inappropriately narrow conclusions

how is the liberalization of food markets progressing market integration and transaction costs in subsistence economies we propose a modification of baulch s parity bounds model to measure the market integration of food markets in developing countries instead of extrapolating a single observation of transaction costs we estimate transaction costs predicted transaction costs compare well with survey data of traders probabilities of market regimes computed on the basis of predicted transaction costs fluctuate significantly and do not support fixed regime probabilities over time the probability of market integration with trade decreases consistently during food shortages increasing either the probability of no trade or loss making trade or the probability of profitable but unexploited trade opportunities the data further support a negative trend in market integration with trade

do firms maximize evidence from professional football this paper examines a single narrow decision the choice on fourth down in the national football league between kicking and trying for a first down as a case study of the standard view that competition in the goods capital and labor markets leads firms to make maximizing choices play by play data and dynamic programming are used to estimate the average payoffs to kicking and trying for a first down under different circumstances examination of actual decisions shows systematic clear cut and overwhelmingly statistically significant departures from the decisions that would maximize teams chances of winning possible reasons for the departures are considered

spice price spikes simulating impacts of saffron price volatility in a gendered local economy wide model summary access to international markets provides smallholders with unprecedented opportunities but also exposes them to world market whims we use a local economy wide impact evaluation lewie model to analyze how the recent global saffron price variability affected morocco s taliouine taznakht region a specialized agro export economy with a stark gender division of labor prices of saffron increased by 71 per year over the 2007 09 period before falling quickly back to their trend our modeling approach allows us to simulate such shocks and evaluate impacts not only on producers but also on the local economies around them in our simulations positive price shocks and increases in productivity both cause large reallocations of labor resources particularly for female workers at harvest time we use monte carlo simulations to evaluate how saffron price variance affects the economy female wage income is especially sensitive to global price variability a 100 increase in saffron price variance leads to 133 increase in female wage income variance but only 36 for males accounting for general equilibrium effects is critical for understanding the ramifications of exposure to export price volatility in poor economies

econometric estimation of producers risk attitudes general methods are proposed for the identification and econometric estimation of the parameters of the distribution of risk attitudes in a producer population the proposed methods also provide the basis for the development of statistical tests of model specification and of behavioral hypotheses econometric risk attitude estimation is shown to be possible under less restrictive conditions than previously believed a moment based version of the general model is applied to indian data and the econometrically estimated risk attitudes are presented and compared to experimental results for a similar group of producers

the economic design of sporting contests what is the optimal number of entrants in a race or the optimal number of teams in a baseball league what is the optimal structure of prizes for a golf tournament or degree of revenue sharing for a football championship how evenly balanced should the competing teams be in the nascar or formula one championships what is the maximum number of entrants per nation to the olympic games that should be permitted what quota of qualifying teams to the soccer world cup should be allocated to the developing nations

multi battle contests abstract we study equilibrium in a multistage race in which players compete in a sequence of simultaneous move component contests players may win a prize for winning each component contest as well as a prize for winning the overall race each component contest is an all pay auction with complete information we characterize the unique subgame perfect equilibrium analytically and demonstrate that it exhibits endogenous uncertainty even a large lead by one player does not fully discourage the other player and each feasible state is reached with positive probability in equilibrium pervasiveness expected effort in the component contests may be non monotonic in the closeness of the race and realized individual effort may exceed the value of the prize by a factor that is proportional to the maximum number of stage victories required

winning isn t everything corruption in sumo wrestling although the theoretical literature on corruption is well developed empirical work in this area has lagged because it has proven difficult to isolate corrupt behavior in the data in this paper we look for evidence of corruption in an unlikely place the highest echelons of japanese sumo wrestling this paper provides strong statistical evidence documenting match rigging in sumo wrestling a non linearity in the incentive structure of promotion leads to gains from trade between wrestlers on the margin for achieving a winning record and their opponents we show that wrestlers win a disproportionate share of the matches when they are on the margin increased effort can not explain the findings winning on the bubble is more frequent when the two competitors have met often in the past success on the bubble tends to rise over the course of a wrestler s career but declines in his last year consistent with the game theoretic predictions wrestlers who are victorious when on the bubble lose more frequently than would be expected the next time they meet that opponent suggesting that part of the payment for throwing a match is future payment in kind systematic differences across wrestling stables suggest that the stables play a role in facilitating the corruption in times of increased media scrutiny the match rigging disappears this abstract was borrowed from another version of this item

determinants of income diversification amongst rural households in southern mali abstract household level panel data from a representative sample of rural households in southern mali describing the different sources of household income are used to examine the determinants of income diversification a conditional fixed effects logit model is employed in the analysis to control for household specific effects we find evidence that poorer households have fewer opportunities in non cropping activities such as livestock rearing and non farm work and hence less diversified incomes this appears to reflect their relative lack of capital which makes it difficult for them to diversify away from subsistence agriculture the results also indicate that households in remote areas are less likely to participate in the non cropping sector than their counterparts closer to local markets while households with educated heads are more likely to participate in the non farm sector than those with illiterate heads the significance of entry constraints in explaining portfolio diversification suggests that the role of government in making assets as well as improved infrastructure available to poorer households is still essential in promoting income diversification

discouragement effect and intermediate prizes in multi stage contests evidence from davis cup abstract the discouragement effect of being the lagging player in multi stage contests is a well documented phenomenon in this study we utilize data from 2447 davis cup matches in team tennis tournaments to test the effect of being behind or ahead on individuals performance with and without intermediate prizes using several different strategies to disentangle the effect of being ahead in the interim score from the effect of selection we find the usual discouragement effect however the discouragement effect disappears after the introduction of intermediate prizes in the form of ranking points the lagging favorite had close to a 20 percentage point greater probability of winning compared to matches without such a prize we show that this result is not driven by the selection of better players into tournaments with intermediate prizes as predicted by previous theoretical studies our empirical findings suggest that intermediate prizes may mitigate or even eliminate the ahead behind effects that arise in multi stage contests

modeling farm households price responses in the presence of transaction costs and heterogeneity in labor markets we develop a farm household model to analyze price responses of farm households this model incorporates various types of transaction costs as well as labor heterogeneity nonproportional variable transaction costs or labor heterogeneity imply that production and consumption decisions become nonseparable even when the household buys or sells labor an empirical model is estimated using data from midwest poland the results show that nonproportional variable transaction costs and labor heterogeneity significantly influence household behavior not all price elasticities however change significantly if these are neglected

interim rank risk taking and performance in dynamic tournaments we empirically study the impact of interim rank on risk taking and performance using data on professionals competing in tournaments for large rewards as we observe both the intended action and the performance of each participant we can measure risk taking and performance separately we present two key findings first risk taking exhibits an inverted u relationship with interim rank revealing information on relative performance induces individuals trailing just behind the interim leaders to take greater risks second competitors systematically underperform when ranked closer to the top despite higher incentives to perform well disclosing information on relative ranking hinders interim leaders

explaining a miracle intensification and the transition towards sustainable small scale agriculture in dryland machakos and kitui districts kenya abstract the transition to sustainable agriculture in tropical small scale farming has been discussed intensively since boserup published her theory on the role of population pressure as a leading factor bosemp s work challenged the malthusian approach to rural transformation recent evidence supports the boserup theory as applied to machakos district kenya this paper aims to establish how much of terracing is directly explained by population density increases as opposed to other district and village level variables by using a retrospective multivariate analysis in machakos and kitui districts kenya the findings suggest that variables such as the distance to major urban markets and the windfall profits from the coffee boom in the late 1970s are at least as important in explaining the investment in the quality of land in machakos and kitui districts

why does on farm storage fail to mitigate price volatility we analyze the role of farm stock management on price volatility under liquidity constraints and heterogeneous price expectations in commodity markets speculative behaviors by stockholders tend to reduce price volatility but this is not the case in certain agricultural markets where speculation by farmers regarding decisions to sell or store grain are subject to liquidity constraints and heterogeneous price expectations like stockholders most farmers sell grain if they expect a price drop in the near future but unlike stockholders they are not necessarily able to purchase grain if they expect a price increase in the next period heterogeneous price expectations can also lead to suboptimal storage decisions further increasing price volatility for these reasons the storage management behavior of farmers often fails to mitigate price drops in the way that speculation by stockholders does we merge historical data on maize prices and household storage collected in burkina faso in order to build a dynamic panel over the 2005 2012 period we show that carry over from one season to the next is associated with unexpected price drops during the preceding lean season and that carry over is associated with more frequent unexpected price drops following the subsequent post harvest season this article is protected by copyright all rights reserved

tournament rewards and risk taking this article considers a lazear rosen tournament model where agents can influence both the spread of their output distribution risk taking and its mean the unique equilibrium induces excessive risk taking and a low level of effort by modifying the tournament to give the highest prize to the agent with the most moderate output a low level of risk taking and high level of effort can be sustained as an equilibrium the first result can be useful to understand the relative performance evaluation puzzle of executive compensation and the second result can be useful to understand puzzling workplace norms promoting mediocrity

psychological pressure in competitive environments evidence from a randomized natural experiment much like cognitive abilities emotional skills can have major eects on performance and economic outcomes this paper studies the behavior of professional subjects involved in a dynamic competition in their own natural environment the setting is a penalty shoot out in soccer where two teams compete in a tournament framework taking turns in a sequence of ve penalty kicks each as the kicking order is determined by the random outcome of a coin ip the treatment and control

some stronger measures of risk aversion in the small and the large with applications the arrow pratt measures of risk aversion for von neumann morgenstern utility functions have become workhorses for analyzing problems in the microeconomics of uncertainty they have been used to characterize the qualitative properties of demand in insurance and asset markets to examine the properties of risk taking in taxation models and to study the interaction between risk and life cycle savings problems to name just a few applications equally importantly they have generated the linear risk tolerance class of utility functions which has provided canonical examples in such diverse areas as portfolio theory and the theory of teams despite these successes there have been a number of areas for which the results have been weaker than hoped it is natural to use the risk aversion measures to compare the behavior of individuals in risky choice situations for example consider the individual portfolio choice problem in a two asset world with a riskless asset and a risky asset if individual a has a uniformly higher arrow pratt coefficient of risk aversion than individual b then b will always choose a portfolio combination with more wealth invested in the risky asset but suppose that both assets are risky now there is no obvious sense in which the more risk averse individual can be said to hold a less risky portfolio but it seems strange that such a simple alteration should destroy the analytics which support the basic intuition similarly consider the basic insurance problem if one individual a is more risk averse than another b in the arrow pratt sense it follows that a will pay a larger premium to insure against a random loss than will b typically though an individual evaluates partial rather than total insurance that is only some gambles can be insured against and others must be retained in this case even when the gambles which are retained are independent from those which are insured it is no longer true that the individual whose arrow pratt measure of risk aversion is higher will pay a larger insurance premium the situation is no better when we consider comparative statics exercises for a single individual decreasing absolute risk aversion in the sense of arrow and

risk taking in selection contests abstract we study contests where the strategic variable is the degree of risk taking rather than the amount of effort the selection efficiency of such contests is examined we show that the selection efficiency of a contest may be improved by limiting the competition in two ways by having a small number of contestants and by restricting contestant quality

when pressure sinks performance evidence from diving competitions tournaments are designed to enhance participants effort and productivity however ranking near the top may increase psychological pressure and reduce performance we empirically study the impact of interim rank on performance using data from international diving tournaments we find that competitors systematically underperform when ranked closer to the top despite higher incentives to perform well

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

measurement of consumer gains from market stabilization for most cases of practical significance in which partial equilibrium analysis is appropriate there is little difference between exact measures of consumer gains from market stabilization and approximations such as expected change in marshallian or hicksian consumer surplus careful specification of the nature of stabilization is more crucial than the choice of welfare measure it is important to represent correctly the demand curvature and supply response and to determine whether general equilibrium responses can be ignored in any event an improved analytical approximation and a simple numerical method for calculating the exact measures make it unnecessary to rely on suspect measures

first in first win evidence on schedule effects in round robin tournaments in mega events the order of actions in contests may have a significant effect on performance in this study we examine the role of the schedule in round robin tournaments with sequential games between three and four contestants our empirical analysis based on soccer fifa world cups and uefa european championships and on two olympic wrestling events reveals that there is a substantial advantage to the contestant who competes in the first and third matches our findings are in line with the hypothesis that winning probabilities in multi stage contests with sequential games are endogenously depending on the schedule of contests as predicted by game theoretical models we also discuss possible ways to reduce the effect of the schedule

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

cognitive performance in competitive environments evidence from a natural experiment competitive situations that involve cognitive performance are widespread in labor markets schools and organizations including test taking competition for promotion in firms and others this paper studies cognitive performance in a high stakes competitive environment the analysis takes advantage of a natural experiment that randomly allocates different emotional states across professional subjects competing in a cognitive task the setting is a chess match where two players play an even number of chess games against each other alternating the color of the pieces white pieces confer an advantage for winning a chess game and who starts the match with these pieces is randomly decided the theoretical analysis shows that in this setting there is no rational reason why winning frequencies should be better than 50 50 in favor of the player drawing the white pieces in the first game yet we find that observed frequencies are about 60 40 differences in performance are also stronger when the competing subjects are more similar in cognitive skills we conclude that the evidence is consistent with the hypothesis that psychological elements affect cognitive performance in the face of experience competition and high stakes
