bidding behavior in descending and ascending auctions this research examines how individual differences and institutional practices influence consumer bidding in auctions bidders may be motivated by different goals e g thrill of winning the item with minimal attention to what they pay for it versus prudence winning the item at a price at or below its perceived value also innate or auctioneer induced differences may exist in the precision and salience of bidder cognitions about the item s value we report two studies on how these motivational and cognitive factors influence bids in descending and ascending auctions respectively each study also manipulated a situational variable wait time at each price step the two auctions realized different average prices for the same item set average bids were higher in the descending versus ascending auction in several study conditions in both auction formats bidders primed with thrill versus prudence bid higher but more precise and or salient values attenuated this goal effect among other results in the descending auction longer wait times elicited higher bids from bidders primed with thrill but not prudence in the ascending auction longer wait times produced lower bids for bidders primed with prudence but not thrill these findings on consumer bidding behavior have practical implications for auction design

socially responsible products what motivates consumers to pay a premium abstractthe motivation to pay a premium for socially responsible products is partly an expression of consumer concern for the well being of those involved in the production process buying a product with a socially responsible label and donating to a charity are similarly motivated actions while there is an extensive literature on the economics of charitable giving that examines motivations to donate as well as on the impacts of labelling on consumer demand there is little overlap between the two literatures we bridge these two literatures by investigating whether consumers have heterogeneous motivations for paying a premium through a laboratory experiment that auctions coffee with hypothetical socially responsible labels that put different weights on in kind versus cash transfers we find that those consumers who prefer an in kind transfer paternalistic altruists are willing to pay a 52 5 price premium over standard coffee those who prefer that most of the premium is paid as cash strong altruis

the impact of fair trade certification for coffee farmers in peru smallholder farmers producing for fair trade market outlets are usually considered to benefit from better prices and stable market outlets however many empirical studies verifying this impact suffer from strong selection bias this study uses a balanced sample of fair trade farmers and likewise nonfair trade producers of organic and conventional coffee from peru to compare the net effects on production income and expenditures wealth and investments and attitudes and perceptions after careful matching we find only modest direct income and production effects but significant changes in organization input use wealth and assets and risk attitudes moreover important differences between farmers with early and more recent ft affiliation are registered

endogenous entry and self selection in private value auctions an experimental study this paper presents the results of an experimental study of endogenous entry in first price independent private value auctions n potential bidders simultaneously decide whether to participate in an auction or receive a known outside option in the second stage entrants submit bids after learning their own private values and the number of entrants an equilibrium model of heterogeneous risk averse bidders implies a self selection effect where bidding in the auction is lower with endogenous entry because only less risk averse bidders enter this effect is confirmed by the experiment we also observe excessive entry relative to the theoretical model

learning by bidding we analyze a dynamic second price auction with an informed bidder and an uninformed bidder who upon seeing a posted price learns whether his valuation is above that price in the essentially unique equilibrium an informed bidder bids in the first period if her valuation is below some cutoff and bids only in the last period otherwise an uninformed bidder bids in every period to optimally change the price unless the price is above his valuation or he is the high bidder this model also provides a rationale behind the use of a secret reserve price in private value settings

universal basic income a viable policy alternative although the need for an efficient roma integration policy is growing in europe surprisingly little robust scientific evidence regarding potential policy costs and expected benefits of alternative policy options has supported the policy design and implementation so far the present study attempts to narrow this evidence gap and aims to shed light on long run economic budgetary and fiscal effects of selected education and employment policies for the inclusion of the marginalised roma in the eu we employ a general equilibrium approach that allows us to assess not only the direct impact of alternative roma integration policies but also to capture all induced feedback effects our simulation results suggest that although roma integration policies would be costly for the public budget in the medium to long run economic budgetary and fiscal benefits may significantly outweigh short to medium run roma integration costs depending on the integration policy scenario and the analysed country the full repayment of the integration policy investment positive net present value may be achieved after 7 to 9 years in terms of the gdp employment and earnings the universal basic income scenario may have the highest potential impacts particularly in the medium to long run

the effect of fair trade affiliation on child schooling evidence from a sample of chilean honey producers we evaluate the impact of fair trade ft affiliation on child schooling within a sample of chilean honey producers with a retrospective panel data approach from a theoretical point of view we argue that ft should have a positive effect on child schooling since it generates a short run pure income effect together with a medium run productivity effect on both adult and child wages on the other hand because of the higher productivity generated by the medium run effect the opportunity cost of child education increases if they work with their parents the direction of the impact of ft affiliation on child schooling is therefore uncertain and requires empirical testing our econometric findings document a positive and significant impact of affiliation years on child schooling after controlling for endogeneity and heterogeneity between the treatment and control sample

the short term impact of unconditional cash transfers to the poor experimental evidence from kenya we use a randomized controlled trial to study the response of poor households in rural kenya to unconditional cash transfers from the ngo givedirectly the transfers differ from other programs in that they are explicitly unconditional large and concentrated in time we randomized at both the village and household levels furthermore within the treatment group we randomized recipient gender wife versus husband transfer timing lump sum transfer versus monthly installments and transfer magnitude us 404 ppp versus us 1 525 ppp we find a strong consumption response to transfers with an increase in household monthly consumption from 158 ppp to 193 ppp nine months after the transfer began transfer recipients experience large increases in psychological well being we find no overall effect on levels of the stress hormone cortisol although there are differences across some subgroups monthly transfers are more likely than lump sum transfers to improve food security whereas lump sum transfers are more likely to be spent on durables suggesting that households face savings and credit constraints together these results suggest that unconditional cash transfers have significant impacts on economic outcomes and psychological well being

a healthier start the effect of conditional cash transfers on neonatal and infant mortality in rural mexico abstract conditional cash transfer programs seek to break the intergenerational transmission of poverty by building the human capital of poor children despite their popularity throughout the developing world relatively little is known about their effect on children s health outcomes this paper evaluates the impact of the mexican conditional cash transfer program progresa on two important health outcomes infant and neonatal mortality it exploits the phasing in of progresa over time throughout rural mexico to identify the impact of the program the paper shows that progresa led to a large 17 decline in rural infant mortality among the treated but did not reduce neonatal mortality on average the benefit cost ratio is between 1 3 and 3 6 tests for heterogeneity show larger declines for some groups including those municipalities whose pre program levels of mortality were above the median and those that prior to the program had higher illiteracy rates and less access to electricity

asset substitution and structured financing this article shows how structured financing can be used to solve the asset substitution problem in a dynamic setting structuring induces the firm s owner to optimally choose the first best operating strategy even though the owner s value function might be locally convex concave which would ordinarily lead to overinvestment underinvestment in risky projects this result is demonstrated in two different continuous time settings one that is based on the risk shifting framework of leland 1998 and one that generalizes the scaled return model of green 1984 it is shown that the contractual nature of the structuring is a key determinant of the issuing firm s dynamic asset volatility furthermore unlike nonstructured financing the default conversion probability of a structured debt security may be increasing decreasing in the firm s total assets structured securities are therefore hedge assets which potentially explains the popularity of structured securities among investors and third party issuers

transfers in cash and in kind theory meets the data we review theoretical explanations for in kind transfers in light of the limited empirical evidence after reviewing the traditional paternalistic arguments we consider explanations based on imperfect information and self targeting we then discuss the large literature on in kind programs as a way of improving the efficiency of the tax system and a range of other possible explanations including the samaritan s dilemma pecuniary effects credit constraints asymmetric information amongst agents and political economy considerations our reading of the evidence suggests that paternalism and interdependent preferences are leading overall explanations for the existence of in kind transfer programs but that some of the other arguments may apply to specific cases political economy considerations must also be part of the story

europe s tired poor huddled masses self selection and economic outcomes in the age of mass migration during the age of mass migration 1850 1913 one of the largest migration episodes in history the united states maintained a nearly open border allowing the study of migrant decisions unhindered by entry restrictions we estimate the return to migration while accounting for migrant selection by comparing norway to us migrants with their brothers who stayed in norway in the late nineteenth century we also compare fathers of migrants and nonmigrants by wealth and occupation we find that the return to migration was relatively low 70 percent and that migrants from urban areas were negatively selected from the sending population keep ancient lands your storied pomp cries she with silent lips give me your tired your poor your huddled masses yearning to breathe free the wretched refuse of your teeming shore send these the homeless tempest tost to me i lift my lamp beside the golden door emma lazarus 1883

robustness of bidder preferences among auction institutions i introduction the answer to the question of how bidders choose to enter one auction versus an alternative competing auction is important to understand in providing a complete picture of the nature of endogenous entry decisions into auctions the issue of how a bidder chooses which among alternative auctions to enter as well as whether to enter an auction at all is of substantial importance to auctioneers attempting to attract bidders to their auctions there is a growing literature addressing issues in endogenous entry in auctions there are several papers such as engelbrecht wiggans 1993 pevnitskaya 2004 and palfrey and pevnitskaya 2008 that consider the decision of whether to enter an auction or not and study the effect of endogenous entry on bidding behavior there is a much larger group for example harstad 1990 engelbrecht wiggans 1993 levin and smith 1994 mcafee 1993 and mcafee and mcmillan 1987 that considers competition between auctioneers in which the auctioneers are competing along some characteristic such as entry price we consider the case in which auctioneers may be competing with each other based on the choice of auction mechanism our interest is in the degree to which the auction mechanism itself might impact the entry decisions of potential bidders of course there would be a direct pecuniary impact of the mechanism in that bidders should be more likely to enter auction mechanisms that they believe allow them to get lower prices but there may be other cognitive issues in regard to the structure of the mechanism that may also impact the choice behavior in ivanova stenzel and salmon iss 2004a we introduced an experimental design aimed at eliciting and measuring preferences subjects might possess for different auction institutions and applied the design to testing bidder preferences between ascending a dynamic mechanism and sealed bid first price a static mechanism auctions it seems reasonable to expect bidders to have preferences between these two auction mechanisms due to the strategic differences between them in a first price auction the winner pays a price equal to his own bid whereas in the ascending auction he pays a price that is an increment above the second highest bid these differences might result in difficulty of deciding how to bid and in the possibility of experiencing some form of regret 1 the design involved having subjects make a choice between entering into a two bidder sealed bid first price auction versus a two bidder ascending auction each with different entry prices by varying the entry prices we could measure the subjects willingness to pay for either auction our main finding in the paper was that while subjects exhibited strong preferences for the ascending auction at equal entry prices they were not willing to pay up to the expected profit difference between the two auctions to participate in an ascending auction thus they ended up entering the supposedly less preferred sealed bid first price auction even in situations in which they would expect to make a higher net surplus including the cost of the entry fee by entering into the ascending auction instead that paper proposed one possible answer to the puzzle that involved assuming that bidders were risk averse in their bidding behavior and then risk averse to the same degree in their auction choice behavior this explanation worked because neither risk averse nor approximately risk neutral bidders should be expected to pay much to enter into an ascending auction instead of a sealed bid first price auction just as we observed in the experiment for the most risk averse bidders this is because while they bid the highest in the first price auction and therefore expected little surplus in the event that they win they consequently end up winning with higher probability than less risk averse bidders this is a trade off risk a verse bidders are willing to accept and consequently it is easy to show that highly risk averse bidders should not be willing to pay much to get into the more lucrative though risky ascending auction

faith based charity and crowd out during the great depression abstract interest in religious organizations as providers of social services has increased dramatically in recent years churches in the u s were a crucial provider of social services through the early part of the twentieth century but their role shrank dramatically with the expansion in government spending under the new deal in this paper we investigate the extent to which the new deal crowded out church charitable spending in the 1930s we do so using a new nationwide data set of charitable spending for six large christian denominations matched to data on local new deal spending we instrument for new deal spending using measures of the political strength of a state s congressional delegation and confirm our findings using a different instrument based on institutional constraints on state relief spending with both instruments we find that higher government spending leads to lower church charitable activity crowd out was small as a share of total new deal spending 3 but large as a share of church spending our estimates suggest that benevolent church spending fell by 30 in response to the new deal and that government relief spending can explain virtually all of the decline in charitable church activity observed between 1933 and 1939

economic status and health in childhood the origins of the gradient the well known positive association between health and income in adulthood has antecedents in childhood not only is children s health positively related to household income but the relationship between household income and children s health becomes more pronounced as children age part of the relationship can be explained by the arrival and impact of chronic conditions children from lower income households with chronic conditions have worse health than do those from higher income households the adverse health effects of lower income accumulate over children s lives part of the intergenerational transmission of socioeconomic status may work through the impact of parents income on children s health

english auctions with resale an experimental study i design and test a simple english auction and two english auctions with resale but with different informational backgrounds all three treatments theoretically have the same equilibrium i find however that the possibility of resale alters behavior significantly in the two treatments with resale subjects deviated from both the nash prediction and the common results about bidding behavior in english auctions subjects tend to overbid when they are certain they can reap the whole surplus in the resale market i employ different models like qre and levels of reasoning and conclude that overbidding can be explained as a rational response to the noisy environment in markets with human participants that is as rational decision making when anticipating others to make errors when the outcome of the resale market is not certain there is significant signaling behavior and auction prices tend to be lower than the nash prediction

eliciting subjective probabilities with binary lotteries abstract we evaluate a binary lottery procedure for inducing risk neutral behavior in a subjective belief elicitation task prior research has shown this procedure to robustly induce risk neutrality when subjects are given a single risk task defined over objective probabilities drawing a sample from the same subject population we find evidence that the binary lottery procedure also induces linear utility in a subjective probability elicitation task using the quadratic scoring rule we also show that the binary lottery procedure can induce direct revelation of subjective probabilities in subjects with popular non expected utility preference representations that satisfy weak conditions

learning to bid the design of auctions under uncertainty and adaptation we examine auction design in a context where symmetrically informed adaptive agents with common valuations learn to bid for a good despite the absence of private valuations asymmetric information or risk aversion bidder strategies do not converge to the bertrand nash equilibrium strategies even in the long run deviations from equilibrium strategies depend on uncertainty regarding the value of the good auction structure the agents learning model and the number of bidders although individual agents learn nash bidding strategies in isolation the learning of each agent by flattening the best reply correspondence of other agents blocks common learning these negative externalities are more severe in second price auctions auctions with many bidders and auctions where the good has an uncertain value ex post

does welfare enable family expenditures on human capital evidence from china summary using the national china household income project 2007 urban survey data and a propensity score matching method this article investigates whether welfare receipt helped enable low income families to spend more on human capital we find that welfare recipient families prioritized spending in health and education relative to their non recipient peers welfare particularly helped poor families afford medical care medicine tuition and fees for noncompulsory education private tutoring for children and purchasing of textbooks we find some evidence that welfare helped recipient families pay for maintenance fees for their residence but receiving welfare also deterred families from having leisure activities

consumers valuation of sustainability labels on meat there are various sustainability certifications and claims for food products that focus on environmental or ethical benefits these claims empower consumers to make informed purchasing decisions that take environmental and ethical considerations into account this paper compares consumers preferences for four types of sustainability claims related to organic meat free range animal welfare and carbon footprint using a choice experiment on a chicken breast product our results show that nine in every ten belgian consumers favor free range claims which are also valued the most highly attracting premiums ranging from 43 to 93 our study also shows that a vast majority of consumers 87 would welcome the introduction of an eu level animal welfare label the carbon footprint labels and the organic labels are less appealing to consumers who have lower willingness to pay for these labels belgian consumers prefer the national belgian organic food logo certified by a private organization to the newly introduced eu organic food logo

auctions with toeholds an experimental study of company takeovers we run experiments on english auctions where the bidders already own a part toehold of the good for sale the theory predicts a very strong explosive effect of even small toeholds while asymmetric toeholds do have an effect on bids and revenues in the lab which gets stronger the larger the asymmetry it is not nearly as strong as predicted we explain this by analyzing the flatness of the payoff functions which leads to large deviations from the equilibrium strategies being relatively costless this is a general fundamental weakness of this type of explosive equilibria which makes them fail when human players are involved our analysis shows that a levels of reasoning model explains the results better where this equilibrium fails moreover we find that although big toeholds can be effective in a takeover battle the cost to acquire them might be higher than the strategic benefit they bring

disease and development evidence from hookworm eradication in the american south this study evaluates the economic consequences of the successful eradication of hookworm disease from the american south the hookworm eradication campaign c 1910 began soon after i the discovery that a variety of health problems among southerners could be attributed to the disease and ii the donation by john d rockefeller of a substantial sum to the effort the rockefeller sanitary commission rsc surveyed infection rates in the affected areas eleven southern states and found that an average of forty percent of school aged children were infected with hookworm the rsc then sponsored treatment and education campaigns across the region follow up studies indicate that this campaign substantially reduced hookworm disease almost immediately the sudden introduction of this treatment combines with the cross area differences in pre treatment infection rates to form the basis of the identification strategy areas with higher levels of hookworm infection prior to the rsc experienced greater increases in school enrollment attendance and literacy after the intervention this result is robust to controlling for a variety of alternative factors including differential trends across areas changing crop prices shifts in certain educational and health policies and the effect of malaria eradication no significant contemporaneous results are found for adults who should have benefited less from the intervention owing to their substantially lower prior infection rates a long term follow up of affected cohorts indicates a substantial gain in income that coincided with exposure to hookworm eradication i also find evidence that eradication increased the return to schooling

collusion in uniform price auctions experimental evidence and implications for treasury auctions in uniform price auctions of shares there exist collusive equilibria in which bidders capture the entire surplus from the auction as well as competitive equilibria in which the auctioneer captures the entire surplus from the auction we provide experimental evidence that in uniform price auctions non binding pre play communication facilitates convergence to collusive equilibrium outcomes on the other hand regardless of the opportunities for communication in discriminatory auction experiments subject strategies conform closely with the unique equilibrium in undominated strategies in which bidders gains are equal to the smallest tick size in the bidding schedule this evidence suggests that uniform price auctions of treasury securities may result in lower revenues than the currently employed discriminatory procedure

is there an effect of incremental welfare benefits on fertility behavior a look at the family cap this analysis exploits the variation across states in the timing of policy implementation to determine if family cap policies lead to a reduction in births to women aged 15 to 34 vital statistics birth data for the years 1989 to 1998 offer no such evidence the data reject a decline in births of more than one percent the finding is robust to multiple specification checks the data also reject large declines in higher order births among demographic groups with high welfare participation rates

an economic model of welfare stigma perhaps the most basic assumption of the economic theory of consumer demand is that more is better than less virtually all of the major propositions of consumer theory can in a certain sense be derived from the assumption that goods are good interestingly however this tenet seems to be violated by the behavior of many individuals in the low income population for many turn out to be eligible for a positive welfare benefit but do not in fact join the welfare rolls for example it has been estimated that in 1970 only about 69 percent of the families eligible for afdc aid to families with dependent children participated in the program see richard michel 1980 the corresponding percentage for afdc u the program for which families with an unemployed male are eligible was only 43 percent and the participation rate in the food stamp program was only 38 percent see maurice mcdonald 1977 this phenomenon has puzzled many investigators because such individuals do not locate on the boundaries of their budget sets consequently most investigators ignore the problem when studying the effects of welfare programs on behavior in this paper this seemingly irrational rejection of an increase in income is modeled as resulting from welfare stigma that is from disutility arising from participation in a welfare program per se 1 the existence of stigma has been amply documented in the sociological literature patrick horan and patricia austin 1974 lee rainwater 1979 where interviews of recipients have often uncovered feelings of lack of self respect and negative self characterizations from participation in welfare nevertheless this phenomenon has not been modeled and many questions consequently remain when is the disutility of participation strong enough to prevent participation shouldn t we expect individuals to weigh the disutility of participation against the potential benefit in their decisions what is the elasticity of participation with respect to the potential benefit also in a slightly different vein how are the work disincentives of welfare affected by stigma these questions have been given scant attention by economists yet they are crucial for our ability to predict the impact of various welfare programs on the lowincome population here these questions are addressed by modeling nonparticipation as a utility maximizing decision the model is developed and estimated for the afdc program 2 the model posits an individual utility function containing not just disposable income but

infant health and longevity evidence from a historical intervention in sweden this paper investigates the potential of an infant intervention to improve life expectancy contributing to emerging interest in the early life origins of chronic disease we track individuals from birth to death and are able to identify age and cause of death the intervention was pioneered in sweden in 1931 1933 and appears to have been pivotal in the emergence of universal infant care programmes in the scandinavian countries during the creation of the welfare state it provided information and support to mothers with an emphasis on nutrition and sanitation while monitoring infant care through home visits and clinics we estimate that the average duration of programme exposure in infancy led to a 1 56 point decline in the risk of infant death 24 of baseline risk and a 2 56 point decline in the risk of dying by age 75 7 0 of baseline risk and these impacts are much larger for children born out of wedlock intervention led declines in the risk of dying after the age of 50 are dominated by reductions in cancer and cardiovascular mortality we find no evidence of selective utilisation and the estimates are similar when we exploit within mother variation in outcomes less

monetary rewards and decision cost in experimental economics a survey of thirty one experimental studies which report data on the comparative effects of monetary rewards and opportunity cost shows 1 several studies in which increased rewards shift the central tendency of the data toward the predictions of rational models 2 in virtually all cases rewards reduce the variance of the data around the predicted outcome this is consistent with a model in which rewards are balanced against decision cost in agent behavior and explicates the argument that when rational models fail it can be attributed to low opportunity cost of deviations from the rational prediction

trends in employment and earnings of allowed and rejected applicants to the social security disability insurance program since the early 1980s changes in the economic environment and in the process for determining eligibility for the social security disability insurance di program have had significant effects on the program first the economic situation and labor force opportunities for lower skilled people continued to decline leading to lower rates of participation in the labor force for less educated men second changes in the eligibility process made it easier to obtain di benefits based on conditions difficult to clearly identify on medical terms alone such as back pain or depression 1 those two factors have likely contributed to a substantial increase in the number of individuals receiving di as well as a significant change in the characteristics of applicants and new beneficiaries over the same period both applicants and new beneficiaries have become younger longer lived more likely to apply because of nonterminal conditions such as back pain or mental health and more likely to be female 2 as a result recent work projects a rapid increase in program costs as greater numbers of beneficiaries stay on the program for more years e g david h autor and duggan 2006 the concurrent developments in the economy and eligibility rules have also fueled the concern that the generosity of di increasingly induces low income workers to apply for and sometimes receive benefits and that some of those beneficiaries would be able to work in the absence of the program indeed a growing body of research suggests that some workers in difficult economic conditions exit the labor force to

economic conditions early in life and individual mortality this paper analyzes the effect of economic conditions early in life on the individual mortality rate later in life using business cycle conditions early in life as an exogenous indicator we have individual data records from dutch registers of birth marriage and death certificates covering an observation window of unprecedented size 1812 2000 these are merged with historical data on macro economic and health indicators we correct for secular changes over time and other mortality determinants we nonparametrically compare those born in a recession to those born in the preceding boom and we estimate duration models where the individual s mortality rate depends on current conditions conditions early in life age individual characteristics including individual socio economic indicators and interaction terms the results indicate a significant negative effect of economic conditions early in life on individual mortality rates at all ages

a utility and cpt based comparison of life insurance contracts with guarantees abstract some recent literature studies whether contracts including financial guarantees can be preferred by a utility maximizing investor the main result for contracts exposed solely to financial risk e g doskeland and nordahl 2008 dichtl and drobetz 2011 is that expected utility theory eut fails to interpret demand for guarantees while cumulative prospect theory cpt is able to support the demand while the development of the financial market has a significant impact on the portfolio choice some other non financial risk might play an important role too in the present paper we take life insurance products as an example where the long term nature of these contracts places a special emphasis on the uncertain lifetime of the investor we incorporate the mortality risk and investigate its effect on the attractiveness of contracts offering minimum interest rate guarantees to eut and cpt investors for this purpose we introduce two approaches for the consideration of multiple risk sources within cpt we illustrate the theoretical framework with numerous simulations and our numerical results show that a long term risk averse eut investor prefers products with guarantees

long run impacts of childhood access to the safety net a growing economics literature establishes a causal link between in utero shocks and health and human capital in adulthood most studies rely on extreme negative shocks such as famine and pandemics we are the first to examine the impact of a positive and policy driven change in economic resources available in utero and during childhood in particular we focus on the introduction of a key element of the u s safety net the food stamp program which was rolled out across counties in the u s between 1961 and 1975 we use the panel study of income dynamics to assemble unique data linking family background and county of residence in early childhood to adult health and economic outcomes the identification comes from variation across counties and over birth cohorts in availability of the food stamp program our findings indicate that the food stamp program has effects decades after initial exposure specifically access to food stamps in childhood leads to a significant reduction in the incidence of metabolic syndrome obesity high blood pressure and diabetes and for women an increase in economic self sufficiency overall our results suggest substantial internal and external benefits of the safety net that have not previously been quantified

the effects of payoff magnitude and heterogeneity on behavior in 2 2 games with unique mixed strategy equilibria the logit version of quantal response equilibrium predicts that equilibrium behavior in games will vary systematically with payoff magnitudes if all other factors are held constant including the nash equilibria of the game we explore this in the context of a set of asymmetric 2x2 games with unique totally mixed strategy equilibria the data provide little support for the payoff magnitude predictions of the logit equilibrium model we extend the theoretical quantal response equilibrium model to allow for heterogeneity and find that the data fit the heterogeneous version of the theory significantly better

canadian contributions to family economics canadian scholars have made substantial contributions to the relatively new field of family economics these include new models of how men and women match in marriage markets and of how decisions are made in multi person households several were early contributors to the literature on married women s labour supply and labour supply in a family context and helped to develop empirical methods in this area a particular focus has been on the impacts of policy relevant parameters such childcare costs on family labour supply and child well being new work on child development the impact of early life conditions and the processes of intergenerational transmission also highlight the importance of family context in determining economic well being

pricing effects when competitors arrive the case of discount certificates in germany this article investigates how overpricing of outstanding certificates also called master certificates changes when competing products that duplicate the features of master certificates are issued i argue that competition effects may be reverted and overpricing may increase rather than decrease after competitors arrive when retail investors fail to detect implications of credit risk differences on certificates values using difference in differences estimations on matched samples i find that overpricing of master certificates decreases after the competing products have been issued but only when the master issuer s credit risk is lower than that of the duplicate issuer while it increases when the credit risk difference is positive these findings are robust to controlling for retail investors demand in various ways thus the study indicates that retail investors failure to detect the value implications of issuers credit risk can undermine product competition

directed giving evidence from an inter household transfer experiment abstract we investigate the determinants of giving in a lab in the field experiment with large stakes study participants in urban mozambique play dictator games where their counterpart is the closest person to them outside their household when given the option dictators do a large fraction of giving in kind in the form of goods rather than cash in addition they share more in total when they have the option of giving in kind compared to giving that can only be in cash qualitative post experiment responses suggest that this effect is driven by a desire to control how recipients use gifted resources standard economic determinants such as the rate of return to giving and the size of the endowment also affect giving but the effects of even large changes in these determinants are significantly smaller than the effect of the in kind option our results support theories of giving where the utility of givers depends on the composition not just the level of gift recipient expenditures and givers thus seek control over transferred resources

welfare and child health the link between afdc participation and birth weight the stated goal of the aid for families with dependent children program is to improve the well being of children in poor families the program has come under considerable attack in recent years from critics who argue that participation in afdc is associated with maternal behaviors that are bad for children we investigate this question using birth weight as a measure of child health we find that participation in afdc during pregnancy is associated with delays in obtaining prenatal care smoking and drinking during pregnancy younger maternal age at the birth and ultimately with lower birth weights even when observable characteristics of the mother are controlled for however we show that when unobservable characteristics of the mother are controlled for there is actually a positive association between participation in afdc and the birth weights of children of white women from poor families we find no association between birth weight and maternal participation in afdc among black children

rationalizable bidding in first price auctions abstract we analyze the consequences of strategically sophisticated bidding without assuming equilibrium behavior in particular we characterize interim rationalizable bids in symmetric first price auctions with interdependent values and affiliated signals we show that 1 every nonzero bid below the equilibrium is rationalizable 2 some bids above the equilibrium are rationalizable 3 the upper bound on rationalizable bids of a given player is a nondecreasing function of her signal in the special case of independent signals and quasi linear valuation functions i the least upper bound on rationalizable bids is concave hence ii rationalizability implies substantial proportional shading for high valuations but is consistent with negligible proportional shading for low valuations we argue that our theoretical analysis may shed some light on experimental findings about deviations from the risk neutral nash equilibrium

an experimental investigation of the seller incentives in the epas emission trading auction the clean air act requires the epa to conduct annual auctions of emission allowances under the discriminative auction rules sellers with the lowest asking prices receive the highest bids this paper studies an inverted version of this auction in which buyers face the same incentives as sellers in the epa auction consistent with theoretical predictions buyers bid above their valuation auction outcomes are inefficient and increasing the number of buyers increases bids buyers facing human opponents compete more aggressively than the risk neutral prediction but bids do not differ systematically from this prediction when buyers face computerized nash robots copyright 1995 by american economic association

governance and contract choice theory and evidence from groundwater irrigation markets abstract this paper examines the role governance institutions play in the adoption of contracts we develop a simple model of the contracting relationship in a setting where unverifiable outcomes exist and use it to interpret data on groundwater irrigation contracts in bangladesh a distinguishing feature of this market is the variety of village level institutions which impose different degrees of punishment for contract violation consistent with the model we find households adopt contracts that rely on unverifiable outcomes which are not formally contractible when punishment for contract violation is weak conversely households adopt contracts that rely on formally contractible and verifiable outcomes when punishment is severe this evidence is consistent with contract terms being chosen optimally given what is or is not formally contractible

inside the war on poverty the impact of food stamps on birth outcomes this paper evaluates the health impacts of a signature initiative of the war on poverty the introduction of the modern food stamp pro gram fsp using variation in the month fsp began operating in each u s county we find that pregnancies exposed to fsp three months prior to birth yielded deliveries with increased birth weight with the largest gains at the lowest birth weights we also find small but statistically insig nificant improvements in neonatal mortality we conclude that the sizable increase in income from fsp improved birth outcomes for both whites and african americans with larger impacts for african american mothers n this paper we evaluate the health consequences of a sizable improvement in the resources available to ameri ca s poorest in particular we examine the impact of the food stamp program fsp which in 2007 provided 34 billion in payments to about 13 million households on infant health our paper makes two distinct contributions first although the goal of the fsp is to increase the nutri tion of the poor few papers have examined its impact on health outcomes second building on work by hoynes and schanzenbach 2009 we argue that the fsp treatment represents an exogenous increase in income for the poor our analysis therefore represents a causal estimate of the impact of income on health an important topic with little convincing evidence due to concerns about endogeneity and reverse causality currie 2009 we use the natural experiment afforded by the nation wide rollout of the modern fsp during the 1960s and early 1970s our identification strategy uses the sharp timing of the county by county rollout of the fsp which was initially constrained by congressional funding authorizations and ultimately became available in all counties by 1975 speci fically we use information on the month the fsp began operating in each of the roughly 3 100 u s counties and examine the impact of the fsp rollout on mean birth weight low birth weight gestation and neonatal mortality throughout the history of the fsp the program para meters have been set by the u s department of agriculture usda and are uniform across states in the absence of the state level variation often leveraged by economists to eval uate transfer programs previous fsp research has typically resorted to strong assumptions as to the comparability of fsp participants and eligible nonparticipants currie 2003 not surprisingly the literature is far from settled as to what casual impact if any the fsp has on nutrition and health hoynes and schanzenbach 2009 use this county rollout to examine the impact of the fsp on food consumption using the psid they found that the introduction of the fsp increased total food spending and decreased out of pocket food spending importantly consistent with the predictions of canonical microeconomic theory the magnitude of the increase in food expenditures was similar to an equivalent sized income transfer implying that most recipient house holds were inframarginal that is they would spend more on the subsidized good than the face value of the in kind transfer as one of the largest antipoverty programs in the united states comparable in cost to the earned income tax credit eitc and substantially larger than temporary assistance to needy families tanf understanding fsp effects is valuable both in its own right and for what it reveals about the relationship between income and health 1

theory and misbehavior of first price auctions recent experimental evidence appears to reject simple nash equilibrium models of bidding behavior in first price auctions the author presents a methodological critique of this evidence existing tests have concentrated on deviations of subjects from predictions in the message space of the action bid deviations the author suggests that it is more natural to evaluate subject behavior in expected payoff space he concludes that the evidence against the simple models is not significant enough to warrant their rejection copyright 1989 by american economic association

multi dimensional reference dependent preferences in sealed bid auctions how most laboratory experiments differ from the field abstract we study bidding behavior in first and second price sealed bid auctions with loss averse agents our model predicts overbidding in first price induced value auctions consistent with evidence from most laboratory experiments substantially different bidding behavior could result in commodity auctions where money and auction item are consumed along different dimensions of the consumption space differences also result in second price auctions our study thereby indicates that transferring qualitative behavioral findings from induced value laboratory experiments to the field may be problematic if subjects are loss averse

the impact of family income on child achievement evidence from the earned income tax credit using an instrumental variables strategy we estimate the causal effect of income on children s math and reading achievement our identification derives from the large nonlinear changes in the earned income tax credit the largest of these changes increased family income by as much as 20 percent or approximately 2 100 between 1993 and 1997 our baseline estimates imply that a 1 000 increase in income raises combined math and reading test scores by 6 percent of a standard deviation in the short run test gains are larger for children from disadvantaged families and robust to a variety of alternative specifications jel h24 h31 i21 i38 j13
