the developmental effect of state alcohol prohibitions at the turn of the twentieth century john p lennon treasurer of the american federation of labor says that seventy percent of the drink bill of the united states is contributed by the american laboring man this means that liquor money is usually bread money meat money shoe money and money that ought to go for clothing american issue maryland edition june 12 1909 as cited in odegard 1928 i introduction work by economists provides considerable evidence consistent with the fetal origins hypothesis that various chronic health outcomes are prompted by an adverse in utero environment e g banerjee et al 2010 deschenes et al 2009 1 while the outcomes and conditions vary across studies the underlying findings emphasize the risks associated with negative exposures during this critical development period most studies in the fetal origins literature exploit the variation afforded by temporary adverse in utero shocks e g famines and focus on early life outcomes e g low birth weight however recent research in this area examines the effects in adulthood of positive in utero and childhood exposures for example hoynes schanzenbach and almond 2012 find that the beneficial effects of food stamp access in utero and during childhood persist into adulthood suggesting the potential for positive and sustained environmental changes during gestation and in early childhood to have long lasting impacts 2 results from bleakley 2007 suggest higher adult incomes among cohorts in the american south with more childhood exposure to hookworm eradication efforts 3 we contribute to this growing literature by exploiting the quasi randomization of alcohol consumption created by state level alcohol prohibition laws passed in the united states in the early part of the twentieth century we argue that such laws represented a positive shock to individuals who were in utero or who were young children around the times of the laws adoption using a large dataset of world war ii enlistees we examine the long term effects of these state prohibition laws on adult educational attainment obesity and height although we do not observe alcohol consumption and hence our results provide intent to treat estimates our design avoids the reporting problems associated with using more recent data on alcohol use we find small but statistically significant effects which do not appear to be the result of pre existing trends for two of the three outcome variables ii background reduced consumption of alcohol could lead to improved outcomes for those individuals in utero or in early childhood during this period through two channels first reduced alcohol consumption by the household members who likely consumed the most alcohol during this period namely men may have shifted resources to other members of the household namely women and children second reduced consumption by pregnant women themselves would reduce fetal exposure to alcohol we provide some historical evidence on the potential relevance of these mechanisms in the context of state level alcohol prohibitions a intrahousehold shift in resources to women and young children liquor traffic as the enemy of the home was a favorite theme of the anti saloon league and other temperance organizations of the time odegard 1928 42 4 the suggestive titles of pamphlets distributed by such organizations included better babies unborn children why babies die and boys worth more than taxes the obvious intention of such propaganda was to convey the message that the saloon culture and the alcohol consumption that came with it resulted in adverse outcomes for children and families that would be reversed under prohibition determining whether or not this reversal materialized is difficult given the lack of historical consumption data state level data on alcohol consumption are not available for this period however national data on consumption and other measures that are likely to be associated with consumption provide some evidence to suggest lower alcohol consumption in the period during which many states adopted alcohol prohibition laws

is there private information in the fx market the tokyo experiment it is a common view that private information in the foreign exchange market does not exist we provide evidence against this view the evidence comes from the introduction of trading in tokyo over the lunch hour lunch re turn variance doubles with the introduction of trading which cannot be due to public information since the flow of public information did not change with the trading rules having eliminated public information as the cause we exploit the volatility pattern over the whole day to discriminate between the two alternatives private information and pricing errors three key re sults support the predictions of private information models first the vola tility u shape flattens greater revelation over lunch leaves a smaller share for the morning and afternoon second the u shape tilts upward an impli cation of information whose private value is transitory finally the morning exhibits a clear u shape when tokyo closes over lunch and it disappears when trading is introduced

non transitive choice event splitting effects or framing effects recent studies have examined possible causes of the robust empirical failure of the transitivity axiom of expected utility theory by pitting regret aversion against alternative explanations such as event splitting effects these tests show that cycles replicate when the latter are controlled but are sensitive to changes in problem representation the control for event splitting effects however does not rule out their contribution to cyclical choices in some circumstances an experiment is reported which investigates this possibility cyclical choices are observed that cannot be due to event splitting effects but appear attributable to within event and between act evaluations of decision problems plus framing effects

the fetal origins hypothesis in finance prenatal environment the gender gap and investor behavior we find that differences in individuals prenatal environments explain heterogeneity in financial decisions later in life an exogenous increase in exposure to prenatal testosterone is associated with the masculinization of financial behavior specifically with elevated risk taking and trading in adulthood we also examine birth weight those with higher birth weight are more likely to participate in the stock market whereas those with lower birth weight tend to prefer portfolios with higher volatility and skewness consistent with compensatory behavior our results contribute to the understanding of how the prenatal environment shapes an individual s behavior in financial markets later in life received may 2 2014 accepted september 30 2015 by editor david hirshleifer

trading patterns and prices in the interbank foreign exchange market the behavior of quote arrivals and bid ask spreads is examined for continuously recorded deutsche mark dollar exchange rate data over time across locations and by market participants a pattern in the intraday spread and intensity of market activity over time is uncovered and related to theories of trading patterns models for the conditional mean and variance of returns and bid ask spreads indicate volatility clustering at high frequencies the proposition that trading intensity has an independent effect on returns volatility is rejected but holds for spread volatility conditional returns volatility is increasing in the size of the spread there is a growing body of theoretical studies on the pattern of trading activity in financial markets with implications for the time series behavior of transactions prices and intensity of trading the empirical literature addressing similar concerns using intraday market data appropriate for such tasks is sparse particularly in the area of the trading of currencies the purpose of this paper is to examine both international patterns of intraday trading activity and the time series properties of returns and bid ask spreads for the deutsche mark dollar exchange rate in the interbank foreign exchange market the goal is to provide information useful in the further development of market microstructure models of trading and to compare empirical findings against theoretical results already in existence the foreign exchange market is in operation twenty four hours a day seven

every minute counts in financial markets abstract this paper represents an introductory study of ultra high frequency minuute by minute data for forex spot rates bid ask reuters quotes on three days autumn 1987 the frequency of price revision size of spread and statistical characteristics are measured the series exhibit time varying leptokurtosis unit roots and first order negative correlation the latter especially in disturbed jumpy markets the effect of time aggregation on these characteristics is examined and variance ratios are analyzed multivariate analysis revealed significant relationships between lagged exchange rates both the own rate and the key deutsche mark us dollar rate and the current spot rate

exploring the intergenerational persistence of mental health evidence from three generations this paper uses data from the 1970 british cohort study to quantify the intergenerational persistence of mental health and the long run economic costs associated with poor parental mental health we find a strong and significant intergenerational correlation that is robust to different covariate sets sample restrictions model specifications and potential endogeneity importantly the intergenerational persistence is economically relevant with maternal mental health associated with lasting effects on the child s educational attainment future household income and the probability of having criminal convictions these results do not disappear after controlling for children s own childhood and adulthood mental health

limit theorems for markets with sequential bargaining this paper models trade as a non coopertative strategic game played at an inlinite sequence of dates a single indivisible commodity is traded buyers and sellers have transferable utility and are characterized by their reservation utilities they meet at random and bargain over the price at which a single unit of the good will be exchanged under a variety of circumstances it is shown that as the costs of search and bargaining become negligible the outcome of the game converges to the competitve flow equilibrium even when there is complete information journal of economic literature classification numbers 022 19x7

decentralized trading strategic behaviour and the walrasian outcome for a market with a finite number of agents pairwise matching and bargaining it is shown that even when the market is frictionless the equilibrium is not necessarily competitive it depends on the amount of information agents use if their behaviour is conditioned only on the sets of agents present and the time the competitive solution is the unique subgame perfect equilibrium if agents have full information and condition their behaviour on some of it there are also noncompetitive equilibria in which behaviour depends on specific information such as the identity of the trading partner and past events

the effect of female education on fertility and infant health evidence from school entry policies using exact date of birth this paper uses age at school entry policies to identify the effect of female education on fertility and infant health we focus on sharp contrasts in schooling fertility and infant health between women born just before and after the school entry date school entry policies affect female education and the quality of a woman s mate and have generally small but possibly heterogeneous effects on fertility and infant health we argue that school entry policies manipulate primarily the education of young women at risk of dropping out of school

search theoretic models of the labor market a survey we survey the literature on search theoretic models of the labor market we show how this approach addresses many issues including the following why do workers sometimes choose to remain unemployed what determines the lengths of employment and unemployment spells how can there simultaneously exist unemployed workers and unfilled vacancies what determines aggregate unemployment and vacancies how can homogeneous workers earn different wages what are the tradeoffs firms face from different wages how do wages and turnover interact what determines efficient turnover we discuss various modeling choices concerning wage determination and the meeting process including recent models of directed search

stature and the standard of living research on the standard of living now emphasizes alternatives or supplements to the national income accounts this paper reviews the results of two decades of research using stature as a measure of health aspects of human welfare after comparing and contrasting stature with per capita income i consider height patterns discovered by economic historians that challenge traditional beliefs about the past including long term trends cycles in heights and the dreadfully small stature of slave children that was followed by catch up growth the paper concludes with comparisons to work in development economics and suggestions for research

bargaining and markets complexity and the competitive outcome abstract rubinstein and wolinsky rev econ stud 57 1990 63 78 consider a simple decentralised market game in which agents meet randomly or voluntarily and bargain over the terms of trade they show that any individually rational price can be sustained as a sequential equilibrium even though the model has a unique competitive outcome here i consider rubinstein and wolinsky s model and show that if complexity costs of implementing strategies enter players preferences together with the standard payoff in the game then every equilibrium is stationary markov and induces the unique competitive price thus i demonstrate that aversion to complexity may provide a justification for the competitive outcome

environment health and human capital in this review we discuss three major contributions economists have made to our understanding of the relationship between the environment and individual well being first in explicitly recognizing how optimizing behavior particularly in the form of residential sorting can lead to nonrandom assignment of pollution economists have employed a wide range of quasi experimental techniques to develop causal estimates of the effect of pollution second economic research has placed a considerable focus on the role of avoidance behavior which is an important component for understanding the difference between biological and behavioral effects of pollution and for proper welfare calculations lastly economic research has expanded the focus of analysis beyond traditional health outcomes to include measures of human capital including labor supply productivity and cognition our review of the quasi experimental evidence on this topic suggests that pollution does indeed have a wide range of effects on individual well being even at levels well below current regulatory standards given the importance of health and human capital as an engine for economic growth these findings underscore the role of environmental conditions as an important factor of production jel i12 i31 j24 q51 q53

trading in networks theory and experiments intermediation is a prominent feature of economic production and exchange two features of intermediation are salient coordination among traders between the source and the destination and competition between alternative combinations of intermediaries we develop a simple model to study these forces and we test the theoretical predictions in experiments our theoretical analysis yields a complete characterization of pricing equilibrium in networks there exist both ecient and inecient equilibria suggesting a key role of coordination among intermediaries strategic interaction leads to either buyer and seller retaining all surplus or intermediaries extracting all surplus we develop conditions on network structure under which these di erent extremal outcomes arise respectively laboratory experiments show that eciency prevails in almost all cases so traders are successful in coordination subjects coordinate on extreme surplus division finally experiments highlight the role of network structure in determining pricing and the

bargaining in a network of buyers and sellers abstract we analyze bargaining between buyers and sellers who are connected by an exogenously given network players can make repeated alternating public offers that may be accepted by any of the responders linked to each specific proposer our purpose is to find the conditions of the network which drive the price distribution in equilibrium this paper uses graph theory tools to provide necessary and sufficient conditions regarding the architecture of networks for the subgame perfect equilibrium of the bargaining game to coincide with the walrasian outcome

the costs of low birth weight birth weight has emerged as the leading indicator of infant health and welfare and the central focus of infant health policy this is because low birth weight lbw infants experience severe health and developmental difficulties that can impose enormous costs on society but would the prevention of lbw generate equally sizable cost savings and health improvements estimates of the return to lbwprevention from cross sectional associations may be biased by omitted variables that cannot be influenced by policy such as genetic factors to address this we compare the hospital costs health at birth and infant mortality rates between heavier and lighter infants from all twin pairs born in the united states we also examine the effect of maternal smoking during pregnancy the leading risk factor for lbw in the united states on health among singleton births after controlling for detailed background characteristics both analyses imply substantially smaller effects of lbw than previously thought suggesting two possibilities 1 existing estimates overstate the true costs and consequences of lbw by at least a factor of four and by as much as a factor of 20 or 2 different lbw preventing interventions have different health and cost consequences implying that policy efforts that presume a single return to reducing lbw will necessarily be suboptimal

does hazardous waste matter evidence from the housing market and the superfund program this paper uses the housing market to develop estimates of the local welfare impacts of superfund sponsored cleanups of hazardous waste sites we show that if consumers value the cleanups then the hedonic model predicts that they will lead to increases in local housing prices and new home construction as well as the migration of individuals that place a high value on environmental quality to the areas near the improved sites we compare housing market outcomes in the areas surrounding the first 400 hazardous waste sites chosen for superfund cleanups to the areas surrounding the 290 sites that narrowly missed qualifying for these cleanups we find that superfund cleanups are associated with economically small and statistically insignificant changes in residential property values property rental rates housing supply total population and types of individuals living near the sites these findings are robust to a series of specification checks including the application of a regression discontinuity design based on knowledge of the selection rule overall the preferred estimates suggest that the local benefits of superfund cleanups are small and appear to be substantially lower than the 43 million mean cost of superfund cleanups

the inefficiency of reuters foreign exchange quotes abstract reuters foreign exchange fxfx page is the world wide predominant information source to foreign exchange traders in this study we compare the indicative spot exchange rate quotes from reuters with their matching futures exchange rates from the chicago mercantile exchange we find that the indicative quotes on reuters fxfx page are inefficient and could be improved by incorporating information from the futures market this casts doubt on the way banks determine these quotes as well as on the informational content of these quotes as an indicator of the current exchange rate

equilibrium in a market with sequential bargaining this paper considers a market where pairs of agents who are interested in carrying out a transaction are brought together by a stochastic process and upon meeting initiate a bargaining process over the terms of the transaction the basic bargaining problem is treated with the strategic approach the paper derives the steady state equilibrium agreements analyzes their dependence on market conditions such as the relative numbers of agents of different types and discusses their relations with the competitive equilibrium outcome and other results in the search equilibrium literature this paper considers a market that operates in the following way pairs of agents who have mutual interest in carrying out a transaction are brought together by a stochastic process when two agents meet they initiate a bargaining process over the terms of the transaction if two agents reach an agreement a transaction takes place and they leave the market of course the bargaining positions and hence the agreement reached in any particular meeting will be affected by the conditions prevailing in the market these will include the chances that each of the negotiating parties have of meeting other partners in the event that the agreement in the current negotiations is delayed also the expected length of time required to achieve an alternative transaction and the expected behavior of alternative partners the study of such a market mechanism is of interest for two reasons firstly it captures some realistic aspects of the trade in certain specific markets e g asset markets such as housing and some labor markets secondly it contributes to an understanding of the micro mechanisms of price formation and their role in shaping market outcomes in both cases the features studied are largely neglected in the traditional market equilibrium analyses the related literature includes the articles by diamond 4 5 diamond and maskin 6 mortensen 8 9 and zusman and bell 13 these articles consider markets of the type described above in which transactions are concluded at pairwise meetings of agents the major difference between our work and these articles is in the approach to the basic bargaining problem in the cited articles it is assumed that a meeting is concluded with an instantaneous agreement which divides the associated surplus in an arbitrary predetermined way when the surplus is assumed to be divided equally the division rule is in fact nash s axiomatic bargaining solution in contrast the present paper treats the basic bargaining problem with the strategic approach see rubinstein 19 which constitutes an attempt to look into the bargaining black box this approach explicitly models the time dimension of the bargaining process describes in detail the bargaining procedure and justifies the agreement as a perfect equilibrium in

from the cradle to the labor market the effect of birth weight on adult outcomes lower birth weight babies have worse outcomes both short run in terms of one year mortality rates and longer run in terms of educational attainment and earnings however recent research has called into question whether birth weight itself is important or whether it simply reflects other hard to measure characteristics by applying within twin techniques using an unusually rich dataset from norway we examine the effects of birth weight on both short run and long run outcomes for the same cohorts we find that birth weight does matter despite short run twin fixed effects estimates that are much smaller than ols estimates the effects on longer run outcomes such as adult height iq earnings and education are significant and similar in magnitude to ols estimates

superfund cleanups and infant health in 1980 outcry over the health effects of toxic waste in love canal new york resulted in the comprehensive environmental response compensation and liability act which became known as superfund superfund was intended to provide a mechanism for conducting remedial clean ups at the most dangerous hazardous waste sites over the years it became the largest and most expensive federal program to deal with toxic waste in the us given the substantial cost and slow rate of clean up there is considerable debate on whether it is in the public interest to continue the program in its current form epa 2006 while the costs of the programs are clear its benefits are not well understood indeed the policy is controversial in part because there is a paucity of reliable information on the program s benefits some previous studies find poorer birth outcomes near a site while others do not see martine vrijheid 2000 however evidence of a correlation between proximity to a site and poor birth outcomes does not necessarily represent a causal effect because populations living near hazardous waste sites are typically different from the general population and their health outcomes are likely to differ even in the absence of negative health effects from exposure for example michael greenstone and justin gallagher 2008 found that residents of areas near hazardous waste sites are more likely to be poor and have lower levels of education than others our project is the first to examine the effect of site cleanups on infant health rather than simply focusing on proximity to a site we focus on single births that occurred within 5km of a superfund site between 1989 and 2003 in five large states florida michigan new jersey pennsylvania and texas the basis of our difference in differences approach is to compare changes in birth outcomes before and after a site s clean up among births to mothers who live within 2 000 meters of the site and among those who live between 2 000 and 5 000 meters away our approach is made feasible by access to confidential vital statistics data that includes the exact street address of the mother s residence our large sample gives us statistical power to detect small effects

the interactive effects of human capital and quality of life on economic growth abstractto bridge the gap in the quality of life qol and economic growth literature and understand the reinforcing effects of qol and human capital on economic development we examine the interactive effects of these two factors on wage growth from 2000 to 2007 at the county level across the united states first a rosen roback model is employed to estimate implicit values of amenities including climate clean air and other natural attributes which are used to generate qol indices second qol human capital represented by the share of college graduates and their interaction serve as key variables in the wage growth model an instrumental variable approach and location fixed effects are used to address endogeneity of human capital and control for location specific unobservable characteristics results suggest that human capital and qol significantly contribute to economic growth and the growth effects are even larger in nonmetropolitan counties importantly we find that the effect of human capital on

deutsche mark dollar volatility intraday activity patterns macroeconomic announcements and longer run dependencies this paper provides a detailed characterization of the volatility in the deutsche mark dollar foreign exchange market using an annual sample of five minute returns the approach captures the intraday activity patterns the macroeconomic announcements and the volatility persistence arch known from daily returns the different features are separately quantified and shown to account for a substantial fraction of return variability both at the intraday and daily level the implications of the results for the interpretation of the fundamental driving forces behind the volatility process is also discussed the efficient market hypothesis contends that financial asset prices provide rational assessments of fundamental values and future payoffs by implication price changes should reflect the arrival and processing of all relevant new information however the proportion of return variability that can be ascribed to public news announcements is low for example cutler poterba and summers 1989 find that even the largest daily price changes in the stock market generally cannot be associated with any significant economic news 1 moreover proxies for the flow of public information e g the number of news items released by reuter s news service berry and hiowe 1994 or dow jones company mitchell and mulherin 1994 explain little of the overall variation thus if private information is ruled out proponents of rational price formation have to assert the existence of important news items

early life health interventions and academic achievement this paper studies the effect of improved early life health care on mortality and long run academic achievement in school we use the idea that medical treatments often follow rules of thumb for assigning care to patients such as the classification of very low birth weight vlbw which assigns infants special care at a specific birth weight cutoff using detailed administrative data on schooling and birth records from chile and norway we establish that children who receive extra medical care at birth have lower mortality rates and higher test scores and grades in school these gains are in the order of 0 15 0 22 standard deviations

a theory of buyer seller networks this paper introduces a new model of exchange networks rather than markets of buyers and sellers it begins with the empirically motivated premise that a buyer and seller must have a relationship a link to exchange goods networks buyers sellers and the pattern of links connecting them are common exchange environments this paper develops a methodology to study network structures and explains why agents may form networks in a model that captures characteristics of a variety of industries the paper shows that buyers and sellers acting strategically in their own self interests can form the network structures that maximize overall welfare

bargaining dynamics in exchange networks abstract we consider a one sided assignment market or exchange network with transferable utility and the dynamics of bargaining in such a market our dynamical model is local involving iterative updates of offers based on estimated best alternative matches in the spirit of pairwise nash bargaining agents are not strategic in our model we establish that when a balanced outcome a generalization of the pairwise nash bargaining solution to networks exists our dynamics converges rapidly to such an outcome

measuring environmental inequality abstract this study presents alternative measures of environmental inequality in the 50 u s states for exposure to industrial air pollution we examine three methodological issues first to what extent are environmental inequality measures sensitive to spatial scale and population weighting second how do sensitivities to different segments of the overall distribution affect rankings by these measures third how do vertical and horizontal inter group inequality measures relate to each other we find substantive differences in rankings by different measures and conclude that no single indicator is sufficient for addressing the entire range of equity concerns that are relevant to environmental policy instead multiple measures are needed

market architectures and institutional testbedding an experiment with space station pricing policies by the year 2000 the national aeronautics and space administration nasa plans to launch and operate an earth orbiting space station for decades into the future the station is expected to play a dominant role in u s space research and in the commercialization of space if the expectations are correct then the station will be a complex of potentially valuable resources and services much sentiment exists within the government that the allocation of those resources should be based on some sort of market oriented policy a more business like approach this paper is part of a larger project that is intended to ascertain what that policy might be

getting the word out enforcement information dissemination and compliance behavior the question for the tax authority is how individuals become aware of enforcement effort to be an effective tool in reducing tax evasion taxpayers must be aware of the current audit and penalty regime we use laboratory experiments to examine the compliance impact of types of information dissemination regarding audit frequency and results the information includes official information disseminated by the tax authority and unofficial or informal communications among taxpayers our results indicate that the effect of the type of post audit information is conditional on whether the taxpayer is well informed of the audit rate prior to filing we find that the tax authority would be served by pre announcing audit rates credibly and by emphasizing the previous period audit frequency in annual reporting of enforcement effort

mother s education and the intergenerational transmission of human capital evidence from college openings we examine the effect of maternal education on birth outcomes using vital statistics natality data from 1970 to 1999 we also assess the importance of four channels through which maternal education may improve birth outcomes use of prenatal care smoking marriage and fertility in an effort to account for the endogeneity of education attainment we use data about the availability of colleges in the womans country in her 17th year as an instrument for maternal education we find that higher maternal education improves infant health as measured by birth weight and gestational age it also increases the probability that a new mother is married reduces parity increases use of prenatal care and reduces smoking suggesting that may be important pathways for the ultimate effect on health our results add to the growing body of literature which suggests that estimates of the returns to education which focus only on increases in wages understate the total return

how markets process information news releases and volatility we examine the impact of scheduled macroeconomic news announcements on interest rate and foreign exchange futures markets we find these announcements are responsible for most of the observed time of day and day of the week volatility patterns in these markets while the bulk of the price adjustment to a major announcement occurs within the first minute volatility remains substantially higher than normal for roughly fifteen minutes and slightly elevated for several hours nonetheless these subsequent price adjustments are basically independent of the first minute s return we identify those announcements with the greatest impact on these markets we examine the impact on interest rate and foreign exchange markets of scheduled macroeconomic news releases such as the employment report the consumer price index cpi and the producer price index ppi many market participants believe that such announcements have a major impact on financial markets indeed a small industry devoted to predicting the figures to be released in upcoming releases has evolved in recent years with the exception of the weekly money supply figures however the impact of such announcements on financial markets has received scant attention 1 this is doubly surprising given the considerable research interest in market volatility since these news releases are a potential source of much of this volatility consider for instance figure 1 as shown there prices in interest rate and foreign exchange futures markets are much more volatile between 8 30 and 8 35 a m eastern time et than during any other five minute trading period including

features of experimentally observed bounded rationality abstract on the basis of experimental evidence reported in the literature the paper draws conclusions about the bounded rationality exhibited by human economic behaviour among the topics discussed are presentation effects caused by superficial analysis strategic reasoning and strategy construction based on reciprocity and fairness avoidance of circular concepts in step by step strategic reasoning ex post rationality and learning direction theory presence of both adaptive and analytic approaches to repeated decision tasks and the absence of quantitative expectations and optimization in typical repeated game strategies

tipping and the dynamics of segregation schelling dynamic models of segregation journal of mathematical sociology 1 1971 143 186 showed that extreme segregation can arise from social interactions in white preferences once the minority share in a neighborhood exceeds a tipping point all the whites leave we use regression discontinuity methods and census tract data from 1970 through 2000 to test for discontinuities in the dynamics of neighborhood racial composition we find strong evidence that white population flows exhibit tipping like behavior in most cities with a distribution of tipping points ranging from 5 to 20 minority share tipping is prevalent both in the suburbs and near existing minority enclaves in contrast to white population flows there is little evidence of nonlinearities in rents or housing prices around the tipping point tipping points are higher in cities where whites have more tolerant racial attitudes

bargaining and efficiency in networks abstract we study an infinite horizon game in which pairs of players connected in a network are randomly matched to bargain over a unit surplus players who reach agreement are removed from the network without replacement the global logic of efficient matchings and the local nature of bargaining in combination with the irreversible exit of player pairs following agreements create severe hurdles to the attainment of efficiency in equilibrium for many networks all markov perfect equilibria of the bargaining game are inefficient even as players become patient we investigate how incentives need to be structured in order to achieve efficiency via subgame perfect but non markovian equilibria the analysis extends to an alternative model in which individual players are selected according to some probability distribution and a chosen player can select a neighbor with whom to bargain

fetal exposures to toxic releases and infant health every year millions of pounds of toxic chemicals thought to be linked to developmental problems in fetuses and young children are released into the air in this paper we estimate the effect of these releases on the health of newborns using data from the toxic release inventory program and vital statistics natality and mortality files we find significant negative effects of prenatal exposure to toxicants on gestation and birth weight we also find that several developmental chemicals increase the probability of infant death the effect is quite sizeable the reported reductions in cadmium toluene and epichlorohydrin releases during the 90s could account for about 3 9 percent of the overall decrease in infant mortality our results are robust to several specification checks such as comparing developmental to non developmental chemicals and fugitive air releases to stack air releases

understanding china s urban pollution dynamics china s ongoing urban economic growth has sharply increased the population s per capita income lowered the count of people living below the poverty line and caused major environmental problems we survey the growing literature investigating the causes and consequences of china s urban pollution challenges we begin by studying how urban population and industrial growth impacts local pollution levels and greenhouse gas production as the urban population grows richer its demand for private transportation and electricity sharply increases such privately beneficial activity exacerbates urban pollution externalities facing these severe environmental challenges china s urbanites increasingly demand quality of life progress we survey the emerging literature investigating the demand for environmental progress in china progress in mitigating externalities hinges on whether the powerful central and local governments choose to address these issues we analyze the political economy of whether government officials have strong incentives to tackle lingering urban externalities we conclude by discussing future research opportunities at the intersection of environmental and urban economics jel o18 p25 p28 q53 r23 r41 r58

markov equilibria in dynamic matching and bargaining games abstract rubinstein and wolinsky rev econ stud 57 1990 63 show that a simple homogeneous market with exogenous matching has a continuum of non competitive perfect equilibria however the unique markov perfect equilibrium of this model is competitive by contrast in the more general case of heterogeneous markets even the markov property is not enough to guarantee the perfectly competitive outcome we define a market game that allows for heterogeneous values on both sides of the market and exhibit a number of examples of non competitive markov perfect equilibria with and without discounting unlike the homogeneous case these equilibria allow for inefficient trades and for trade at non uniform prices the non competitive equilibrium may be unique

inequality at birth some causes and consequences recent research shows that health at birth is affected by many factors including maternal education behaviors and participation in social programs in turn endowments at birth are predictive of adult outcomes and of the outcomes of future generations exposure to environmental pollution is one potential determinant of health at birth that has received increasing attention a large literature outside of economics advocates for environmental justice and argues that poor and minority families are disproportionately exposed to environmental hazards i provide new evidence on this question showing that children born to less educated and minority mothers are more likely to be exposed to pollution in utero and that white college educated mothers are particularly responsive to changes in environmental amenities i estimate that differences in exposure to toxic releases may explain 6 of the gap in incidence of low birth weight between infants of white college educated mothers and infants of black high school dropout mothers this abstract was borrowed from another version of this item

seasonality in foreign exchange volatility the paper reports further empirical evidence on seasonality in foreign exchange volatility using high frequency data using a basis of the signal plus noise framework the approach decomposes tick by tick reuters fxfx quotes into a random walk and a stationary component termed the efficient price and the pricing error respectively the efficient price is not directly observable and is an approximation of the true value the pricing error captures the deviation between the observed indicative quote and the efficient price under the proposed model daily and intraday volatilities of the efficient price are estimated a pronounced pattern of volatility is uncovered and appears related to the daily activity cycle of major organized stock exchanges it is argued that seasonality in volatility is a symptom of foreign exchange markets results confirm andersen and bollerslev s findings that significant seasonal effects are one important determinant of overall volatility at high frequencies

statistical study of foreign exchange rates empirical evidence of a price change scaling law and intraday analysis abstract in this paper we present a statistical analysis of four foreign exchange spot rates against the u s dollar with several million intra day prices over 3 years the analysis also includes gold prices and samples of daily foreign exchange prices over 15 years the mean absolute changes of logarithmic prices are found to follow a scaling law against the time interval on which they are measured this empirical law holds although the distributions of the price changes strongly differ for different interval sizes systematic variations of the volatility are found even during business hours by an intra day analysis of price changes seasonal heteroskedasticity is observed with a period of one day as well as one week as the result of an analogous intra week analysis taking this into account is necessary for any future study of intra day price change distributions and their generating process the same type of analysis is also made for the bid ask spreads

intrafamily resource allocations a dynamic structural model of birth weight using large american and british survey data this paper provides structural estimates of the production functions for birth weight and fetal growth in addition to maternal smoking we estimate the impact of when a mother stops work which has not been considered in the literature mothers work interruptions of up to 3 months before birth have a positive effect on birth outcomes especially among british children parental behavior appears to respond to child idiosyncratic endowments in a way that suggests that parents have inequity aversion concerns evidence in favor of inequity aversion emerges also from the analysis of breast feeding decisions

the role of information and social interactions in retirement plan decisions evidence from a randomized experiment this paper analyzes a randomized experiment to shed light on the role of information and social interactions in employees decisions to enroll in a tax deferred account tda retirement plan within a large university the experiment encouraged a random sample of employees in a subset of departments to attend a benee ts information fair organized by the university by promising a monetary reward for attendance the experiment multiplied by more than e ve the attendance rate of these treated individuals relative to controls and tripled that of untreated individuals within departments where some individuals were treated tda enrollment e ve and eleven months after the fair was signie cantly higher in departments where some individuals were treated than in departments where nobody was treated however the effect on tda enrollment is almost as large for individuals in treated departments who did not receive the encouragement as for those who did we provide three interpretations differential treatment effects social network effects and motivational reward effects to account for these results

stochastic stability for roommate markets we show that for any roommate market the set of stochastically stable matchings coincides with the set of absorbing matchings this implies that whenever the core is non empty e g for marriage markets a matching is in the core if and only if it is stochastically stable i e stochastic stability is a characteristic of the core several solution concepts have been proposed to extend the core to all roommate markets including those with an empty core an important implication of our results is that the set of absorbing matchings is the only solution concept that is core consistent and shares the stochastic stability characteristic with the core

what is the optimal speed limit on freeways abstract when choosing his speed a driver faces a trade off between private benefits time savings and private costs fuel cost and own damage and injury driving faster also has external costs pollution adverse health impacts and injury to other drivers this paper uses large scale speed limit increases in the western united states in 1987 and 1996 to address three related questions first do the social benefits of raising speed limits exceed the social costs second do the private benefits of driving faster exceed the private costs third what is the optimal speed limit i find that a 10 mph speed limit increase on highways leads to a 3 4 mph increase in travel speed 9 15 more accidents 34 60 more fatal accidents and elevated pollutant concentrations of 14 24 carbon monoxide 8 15 nitrogen oxides 1 11 ozone and 9 higher fetal death rates around the affected freeways using these estimates i find that the social costs of speed limit increases are two to seven times larger than the social benefits in contrast many individual drivers would enjoy a net private benefit from driving faster privately a value of a statistical life vsl of 6 0 million or less justifies driving faster but the social planner s vsl could be at most 0 9 2 0 million to justify higher speed limits i conclude that the optimal speed limit was lower but not much lower than 55 mph

introduction to experimental game theory the title experimental game theory refers to experiments whose goal is to learn about general principles of strategic behavior as opposed to the performance of specific institutions twenty five years ago it would have been startling to see experimental modifying game theory in this way or to find an entire issue of an economics journal devoted to game experiments if this now seems natural it is a tribute to the increasingly

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

a note on economic news and intraday exchange rates abstract measured with intraday data in a 1987 1991 sample period the mark dollar exchange rate was affected by unanticipated information about the trade deficit and the consumer price index the exchange rate showed no significant response to news about money supply industrial production the producer price index or unemployment trade deficit surprises were negatively correlated with the value of the dollar as expected cpi surprises showed a positive correlation as would be predicted by sticky price models of exchange rates the market s reaction to the 8 30am trade deficit announcement was complete by 9am but the market s response to the cpi announcement was not as immediate no significant reaction had occurred by 9am and the spot price did not fully digest the information until 1pm significant responses were present in the 9am 11am and noon hours alternate measures of currency returns failed to explain this delayed response

the effects of social networks on employment and inequality we develop a model where agents obtain information about job opportunities through an explicitly modeled network of social contacts we show that employment is positively correlated across time and agents moreover unemployment exhibits duration dependence the probability of obtaining a job decreases in the length of time that an agent has been unemployed finally we examine inequality between two groups if staying in the labor market is costly and one group starts with a worse employment status then that group s drop out rate will be higher and their employment prospects will be persistently below that of the other group

are risk regulators rational evidence from hazardous waste cleanup decisions a large literature in economics and social science focuses on how people reason about risks reactions of individuals to risk frequently depart from behavior predicted by full information variants of expected utility theory risk regulators are human and are subject to political pressures that are reflective of people s attitudes toward risk as a result the public policies they espouse may reflect errors in judgment about risk many biases stem from misperceptions of risk individuals overestimate small probabilities overestimate the risks associated with highly publicized dangers and have preferences over the manner not just the magnitude in which risks arise environmental risks associated with hazardous waste sites may be particularly prone to such errors since they involve small risks that are highly publicized indeed the general public ranks hazardous waste sites as the leading environmental risk a growing literature also analyzes how the decisions of risk regulators depart from choices predicted in a standard benefit cost framework as roger g noll and james e krier 1990 point out since regulators are both human and political their decisions may reflect risk biases regulators may exhibit these biases as individuals and because their constituents will express regulatory demands based on risk perceptions risk regulators may take into account the identity of the parties exposed to risk the level of scrutiny by interest groups the nature of congressional representation of affected constituents and the degree of political activity by potentially exposed individuals 3 errors in risk perceptions and risk decisions cause individuals to diverge from expected utility maximization similar errors by policy makers and the influence of risk politics cause regulators to diverge from social welfare maximization this paper examines decisions made by federal and state regulators at hazardous waste sites addressed by the superfund program to determine how their decisions diverge from those predicted by expected utility theory and benefitcost analysis we analyze whether risk perceptions and politics influence two decisions central to the how clean is clean debate at superfund sites the selection of chemical cleanup targets and the expenditure of remediation funds at these contaminated sites we also explore the interactive influence of risk perception factors and political demands previous research on the regulation of chemical risks in standard setting indicates that decisions reflect evidence of risk biases and responsiveness to political factors in assessing the determinants of the epa s decision to cancel pesticide registration maureen l cropper et al 1992 found that the epa was more likely to cancel a pesticide in instances featuring higher risks to the maximally exposed individual user lower benefits associated with continued use of the pesticide higher values of intervention by environmental groups mea viscusi harvard law school harvard university cambridge ma 02138 hamilton sanford institute of public policy duke university durham nc 27708 we have benefited from the comments from two referees and the excellent research assistance of jason bell kristen blann jahn hakes and robert malme research support was provided under cooperative agreement no cr 823604 01 from the u s environmental protection agency office of policy planning and evaluation dr alan carlin and dr suzanne giannini spohn served as contract officers all views and errors expressed are our own l see u s environmental protection agency epa 1987 for a report on this survey evidence 2 this theme is also articulated in richard j zeckhauser and viscusi 1990 noll 1989 provides a more general assessment of the interaction between political concerns and regulatory policy which is a central theme of this paper 3political factors have long played a prominent role in local hazardous waste policies see among others linda cohen 1981 howard kunreuther and douglas easterling 1990 1992 and kunreuther and rajeev gowda 1990

regulation and capitalization of environmental amenities evidence from the toxic release inventory in massachusetts environmental regulation in the united states has undergone a slow evolution from command and control strategies towards market based regulations one such innovation is the toxics release inventory tri a regulation that requires polluting e rms to publicly disclose information about their toxic emissions the basic tenet of this regulation is that it corrects for informational asymmetries between polluters and households allowing communities to pressure polluters to decrease their emissions policy makers have judged the tri a tremendous success as national releases declined by 43 between 1988 and 1999 yet many of the fundamental problems which are known to lead to the classic failure of the coase theorem such as high transaction costs and dife culties in organizing cast doubt on the effectiveness of disclosure rules alone to lead to an efe cient outcome in the caseof pollution we use an event study methodology with high quality data on house prices and other local attributes to assess the extent to which the public values changes in toxic releases and thus the success of tri our major e ndings include 1 declines in toxic releases appear unrelated to any political economy variables that might lead to public activism 2 initial information released under tri had no signie cant effect on the distribution of house prices and 3 house prices show no signie cant impact of declines in reportedtoxic releases over time standard errors aresmall enoughthat we can reject the hypothesis that large declines in toxic releases lead to more than a 0 5 increase in house prices these results also hold when we control for differences in the availability of information on tri and the possible effect of expectations our e ndings cast doubt on the ability of the public to process complex information on hazardous emissions and support the coase theorem in that right to know lawssuch as tri may not be the most effective form of environmental regulation

identifying sorting in theory assortative matching between workers and rms provides evidence of the complementarities or substitutes in production the presence of complementarities is important for policies that aim to achieve the optimal allocation of resources for example unemployment insurance we argue that using wage data alone it is virtually impossible to identify whether assortative matching is positive or negative even though we cannot identify the sign of the sorting we can identify the strength i e the magnitude of the cross partial and the associated welfare loss we show rst that the wage for a given worker is non monotonic in the type of his employer this is due to the fact that in a sorting model wages reect the opportunity cost of mismatch we show analytically that this non monotonicity prevents standard rm xed eects to correlate with the true type of the rm we then propose an alternative procedure that measures the strength of sorting in the presence of search frictions knowing the strength of sorting facilitates the measurement of the output loss due to mismatch

heterogeneity irreversible production choices and efficiency in emission permit markets abstract this paper investigates a class of market mechanisms for environmental regulation based on the clean air act tradable discharge permit program laboratory market experiments capture some of the more salient institutional features and focus on issues of firm technological heterogeneity and irreversible investment regarding the operation of the permit market experimental results suggest that higher degrees of abatement cost heterogeneity may lead to reduced trade volume while the implications of increased cost heterogeneity regarding price volatility are mixed finally increased cost heterogeneity appears to result in decreased laboratory efficiency

matching and efficiency in the baseball free agent system an experimental examination this article presents the results of an experimental study investigating the problem of allocating heterogeneous indivisible objects using market like mechanisms the object of study is the market for professional baseball players in their free agent year we investigate both the current free agency system and a variant of the current system instituted informally by the teams and ruled illegal by arbitrators we then propose and test a new alternative matching mechanism which proves to have quite a few desirable characteristics

financial trouble across generations evidence from the universe of personal loans in denmark do people end up in financial trouble simply because of adverse shocks to income and wealth or is financial trouble related to persistent differences in financial attitudes and behavior that may be transmitted from generation to generation we address this question using a new administrative data set with longitudinal information about defaults for the universe of personal loans in denmark we provide non parametric evidence showing that the default propensity is more than four times higher for individuals with parents who are in default compared to individuals with parents not in default this intergenerational relationship is apparent soon after children move into adulthood and become legally able to borrow the intergenerational relationship is remarkably stable across age groups levels of loan balances parental income levels childhood school performance time periods and different measures of financial trouble basic theory points to three possible explanations for the correlation across generations in financial trouble i children and parents face common shocks ii children and parents insure each other against adverse shocks iii financial behavior differs across people and is transmitted across generations our evidence indicates that the last explanation is the most important finally we show that the intergenerational correlation in financial trouble is not fully incorporated in interest setting on loans pointing to the existence of an interest rate externality in the market for personal loans

intra day and inter market volatility in foreign exchange rates four foreign exchange spot rate series recorded on an hourly basis for a six month period in 1986 are examined a seasonal garch model is developed to describe the time dependent volatility apparent in the percentage nominal return of each currency hourly patterns in volatility are found to be remarkably similar across currencies and appear to be related to the opening and closing of the worlds major markets robust lm tests designed to deal with the extreme leptokurtosis in the data fails to uncover any evidence of misspecification or the presence of volatility spillover effects between the currencies or across markets

the use of information system technology to develop tests on insider trading and asymmetric information issues related to insider trading remain popular research topics empirical studies using historical data are limited by two key factors 1 the inability to identify exactly who possesses inside information and 2 the inability to identify the accuracy of information possessed advances in information system technology enable us to overcome these problems in the laboratory using this technology we create a research shell to conduct experiments where we can identify the exact type and quality of information accessible by each trader our system includes the capability to monitor individual activities in accessing inside information the system can automatically impose a monetary penalty if random monitoring identifies a trader accessing inside information our experiments involve traders who receive access to inside information without initial knowledge of the quality of that information the results indicate that traders were able to outperform the market if penalties for being caught accessing such information were not included once penalties were included however no significant performance differences were observed finally in a second set of experiments involving a simplified market with infrequent electronic monitoring and low penalty amounts inside information seemed to be rapidly and effectively disseminated to traders possessing no inside information

tax morale affects tax compliance evidence from surveys and an artefactual field experiment our working hypothesis is that cross cultural differences in tax compliance behavior have foundations in the institutions of tax administration and citizen assessment of the quality of governance tax compliance being a complex behavioral issue its investigation requires use of a variety of methods and data sources results from artefactual field experiments conducted in countries with substantially different political histories and records of governance quality demonstrate that observed differences in tax compliance levels persist over alternative levels of enforcement the experimental results are shown to be robust by replicating them for the same countries using survey response measures of tax compliance

markov equilibria in a model of bargaining in networks abstract we study the markov perfect equilibria mpes of an infinite horizon game in which pairs of players connected in a network are randomly matched to bargain players who reach agreement are removed from the network without replacement we establish the existence of mpes and show that mpe payoffs are not necessarily unique a method for constructing pure strategy mpes for high discount factors is developed for some networks we find that all mpes are asymptotically inefficient as players become patient
