state lotteries and consumer behavior abstract this paper investigates two central issues regarding state lotteries first analyses of multiple sources of micro level data demonstrate that household lottery spending is financed primarily by a reduction in non gambling expenditures not by a reduction in expenditures on other forms of gambling the introduction of a state lottery is associated with an average decline of 46 per month or 2 4 percent in household non gambling expenditures low income households reduce non gambling household expenditures by 2 5 percent on average 3 1 percent when the state lottery includes instant games these households experience statistically significant declines in expenditures on food and on rent mortgage and other bills second consumer demand for lottery products responds positively to the expected value of the gamble controlling for other statistical moments and product characteristics including the nominal top prize amount this finding is consistent with informed choice among consumers of lottery products although other forms of irrational or misinformed choice cannot be ruled out

the enduring power of coase abstractby many measures ronald coase has been among the most influential economists of the past 60 years why is this so we suggest that coase s work has enduring appeal to and insight for social scientists in part because it addresses the biggest and most important social problems how do we solve governance and coordination problems when limited information common resource issues and public good issues produce conflicts among several people at once any scholar who works on issues of corporate or common pool governance pollution allocation of seats on legislative committees regulation of systemic risk in financial markets provision of military forces patent thickets creation of optimal communications networks regulation of decreasing cost industries or compensation of corporate officers can see his or her work stemming from several of coase s original insights just as john nash s work reshaped economic theory almost every field of economics and political science is shaped by coasean insights

the who and why of lottery empirical highlights from the seminal economic literature lotteries operate today in many countries around the world this type of gambling is usually run by governments and is sometimes described as regressive lottery is an unfair bet so explaining the purchase of lottery tickets by risk averse consumers has been a challenge for economic theory lotteries can be analysed from either of two economic perspectives as a source of public revenue or as a consumer commodity in this paper the state of economic research on lotteries is reviewed focusing on its main empirical findings

the proper scope of government theory and an application to prisons when should a government provide a service in house and when should it contract out provision we develop a model in which the provider can invest in improving the quality of service or reducing cost if contracts are incomplete the private provider has a stronger incentive to engage in both quality improvement and cost reduction than a government employee has however the private contractor s incentive to engage in cost reduction is typically too strong because he ignores the adverse effect on noncontractible quality the model is applied to understanding the costs and benefits of prison privatization

do regions benefit from active labour market policies a macroeconometric evaluation using spatial panel methods dauth w hujer r and wolf k do regions benefit from active labour market policies a macroeconometric evaluation using spatial panel methods regional studies the effect of active labour market policies on all job seekers in a region is assessed using the variation in the participation in these programmes across regions over time the starting point is an augmented regional matching function which is extended by allowing for a heterogeneous search effectiveness parameter for current participants and job seekers who finished a measure recently a spatial dynamic panel data model is estimated by using a quasi ml estimation procedure it is found that job schemes in the non profit sector wage subsidies and advancement of apprenticeships significantly increase the regional number of matches

the relative regressivity of seven lottery games we study the implicit tax incidence of raising state revenue through a monopoly state run lottery using a new dataset on individual minnesota lottery game sales by zip code we use the bootstrap to compute ses and construct confidence intervals for suits indices of seven lottery products we conclude that the implicit tax on each product is regressive and find statistically significant differences in regressivity between some products minnesota s newly introduced g3 instant scratch product printed at time and place of purchase is also the most regressive lottery game

relative efficiencies and comparative advantages in job search a model of employed and unemployed job search is estimated from a panel of new entrants into the labor force as well as prime age workers after investigating the relative efficiency of the two mai

economica coase lecture reference points and the theory of the firm i argue that it has been hard to make progress on coase s theory of the firm agenda because of the difficulty of formalizing haggling costs i propose an approach that tries to move things forward using the idea of aggrievement costs and apply it to the question of whether a transaction should be placed inside a firm in house production or in the market place outsourcing

the reference point approach to the theory of the firm an introduction there is a small but growing literature on the reference point approach to incomplete contracts as formulated by hart and moore the reference point approach has begun to be applied to the theory of the firm in 3 recent papers this introduction reviews the main theoretical aspects of each of these papers it then discusses the relationship between the reference point approach to the firm the transaction cost approach and the property rights approach here it is argued that the reference point approach is a step back towards ex post inefficiencies away from reliance on ex ante inefficiencies

a model of competition between unemployed and employed job searchers an application to the unemployment outflow rate in britain this paper proposes a model to explain the allocation of new jobs to workers the central innovation is the analysis of the competition for jobs between employed and unemployed job searchers it is argued that the endogeneity of the fraction of the employed engaging in search is a crucial determinant of the unemployment outflow rate the model is applied to the unemployment outflow rate in britain the model fits the data well and encompasses its main rival copyright 1993 by royal economic society

vertical integration and firm boundaries the evidence since ronald h coase s 1937 seminal paper a rich set of theories has been developed that deal with firm boundaries in vertical or input output structures in the last twenty five years empirical evidence that can shed light on those theories also has been accumulating we review the findings of empirical studies that have addressed two main interrelated questions first what types of transactions are best brought within the firm and second what are the consequences of vertical integration decisions for economic outcomes such as prices quantities investment and profits throughout we highlight areas of potential cross fertilization and promising areas for future work

do employers use unemployment as a sorting criterion when hiring evidence from a field experiment the stigma associated with long term unemployment spells could create large inefficiencies in labor markets while the existing literature points toward large stigma effects it has proven difficult to estimate causal relationships using data from a field experiment we find that long term unemployment spells in the past do not matter for employers hiring decisions suggesting that subsequent work experience eliminates this negative signal nor do employers treat contemporary short term unemployment spells differently suggesting that they understand that worker firm matching takes time however employers attach a negative value to contemporary unemployment spells lasting at least nine months providing evidence of stigma effects

unemployment duration unemployment benefits and labor market programs in sweden abstract standard search theory as well as some empirical evidence suggest that an unemployed individual s probability of entering employment increases as he approaches the time when unemployment benefits are due to expire this pattern may not carry over to a country like sweden where labor market programs are targeted at the long term unemployed at risk of benefit exhaustion the paper examines transitions out of unemployment using data on unemployed individuals in sweden a semi parametric competing risks model for transitions to employment labor market programs and non participation is estimated there is some evidence that the exit rate from unemployment to employment increases as benefit exhaustion is approached

what is the optimal design for lottery linked savings programmes in this article we determine the optimal design of lottery linked savings lls programmes lls vehicles such as lottery bonds are financial instruments that preserve depositors principal but provide randomized variable returns to these depositors through periodic lottery drawings in lieu of the regular coupon payments traditionally received by bondholders this type of asset is very popular in europe we note that the framing of lls instruments is linked to their popularity and we attempt to elucidate that link and thereby determine the optimal structure of payments for lls programmes our goal is to frame lls programmes in a manner that both maximizes their investors satisfaction and preserves their ability to serve as inexpensive sources of capital for their issuers we demonstrate that the optimal pay off structure is characterized by a high level of skewness as investors are willing to accept a decrease in the small and medium prizes of the lottery in exchange for an increase in the grand pri

an empirical test of the theory of on the job search preunemployment search is the fundamental labor market process generating beneficial effects of advance notice yet theory indicates that workers receiving notice may not search whereas others may search even without advance notice our weighted results

gambling by auctions abstract we provide theoretical and empirical analysis of a selling mechanism used by an internet web site that combines important features of auctions and gambling this is the first analysis of such a selling mechanism which provides insights into how the two kinds of behavior might be related in real life the winner of the object is the bidder with the highest bid not submitted by any other bidder in the equilibrium of our game theoretical model each bid made with positive probability yields the same probability of winning bidders are more likely to submit higher bids and the bid distribution does not depend on the value of the object or the highest bid allowed if one controls for the number of bidders most of these key theoretical predictions are confirmed by the data

job search stigma effect and escape rate from unemployment this article formulates job search models incorporating certain types of the stigma effect of unemployment it is assumed that the probability of getting a job offer given the unemployment individual contacts the firm is influenced by the duration of unemployment and is justified in a signaling context the optimal search is analyzed for one sector as well as across several independent labor market segments it is shown that there are reasonably general conditions on the search environments for which both the individual reservation wage and escape rate are negative duration dependent a fact observed in empirical studies

inflation and unemployment the world economy today is vastly different from the 1930s when seymour harris the chairman of this meeting infected me with his boundless enthusiasm for economics and his steadfast confidence in its capacity for good works economics is very different too both the science and its subject have changed and for the better since world war ii but there are some notable constants unemployment and inflation still preoccupy and perplex economists statesmen journalists housewives and everyone else the connection between them is the principal domestic economic burden of presidents and prime ministers and the major area of controversy and ignorance in macroeconomics i have chosen to review economic thought on this topic on this occasion partly because of its inevitable timeliness partly because of a personal interest reaching back to my first published work in 1941

raiding opportunities and unemployment this article studies the impact of raiding opportunities in a labor market in which worker abilities differ recruiting firms can either raid an elsewhere employed worker of known ability by bidding up his wage or go through costly search to find a good worker among the unemployed in equilibrium all types of workers experience unemployment high ability workers involuntarily the raiding opportunities give rise to involuntary unemployment without changing the basic properties of the competitive model and thus suggest new implications of various institutional parameters on unemployment in particular unemployment compensation minimum wages wage taxation and search requirements

thinking about the firm a review of daniel spulber s the theory of the firm in this review i describe how economists have moved beyond the firm as a black box to incorporate incentives internal organization and firm boundaries i then turn to the way that the theory of the firm is treated in daniel spulber s book the theory of the firm microeconomics with endogenous entrepreneurs firms markets and organizations spulber s goal is to explain why firms exist how they are established and what they contribute to the economy to accomplish this spulber defines a firm to be a transaction institution whose objectives differ from those of its owners for spulber this separation is the key difference between the firm and direct exchange between consumers i raise questions about whether this is a useful basis for a theory of the firm jel d21

shocks individual risk attitude and vulnerability to poverty among rural households in thailand and vietnam summary we examine whether the experience of shocks influences individual risk attitude we measure the risk attitude of more than 4 000 households in thailand and vietnam via a simple survey item the experience of adverse shocks which is typical for poor and vulnerable households is related to a higher degree of risk aversion even when controlled for a large set of socio demographic variables therefore shocks perpetuate vulnerability to poverty via their effect on risk attitude we extend this general finding to various categories of shocks and find differences between thailand and vietnam this suggests that risk coping strategies profit from case specific design

the sunk cost fallacy in penny auctions this article theoretically and empirically analyses behaviour in penny auctions a relatively new auction mechanism as in the us dollars or war of attrition players in penny auctions commit higher non refundable costs as the auction continues and only win if all other players stop bidding i first show that in any equilibria that does not end immediately players bid probabilistically such that the expected profit from every bid is zero then using two large data sets covering 166 000 auctions i calculate that average profit margins actually exceed 50 to explain this deviation i incorporate a sunk cost fallacy into the theoretical model to generate a set of predictions about hazard rates and player behaviour which i confirm empirically while players do slowly learn to correct this bias and there are few obvious barriers to competition activity in the market is rising and concentration remains relatively high

job competition and the wage curve longhi s job competition and the wage curve regional studies the wage curve literature consistently finds a negative relationship between regional unemployment rates and regional wages the most widely accepted theoretical explanations interpret the unemployment rate as a measure of job competition this paper proposes new ways of measuring job competition alternative to the unemployment rate and finds that the negative relationship still holds when job competition is measured following the job search literature while for men the wage impact of the theoretically based measures of job competition is rather similar to the wage impact of the unemployment rate for women the difference is substantial longhi s la competition pour l emploi et la courbe des salaires regional studies la documentation sur la courbe des salaires affirme systematiquement que le taux de chomage regional est en correlation faible avec les salaires regionaux les explications theoriques les plus recues considerent le taux de

leviathan governments and carbon taxes costs and potential benefits abstract this paper addresses positive aspects of the global warming debate that so far has been concerned by and large with normative issues the paper considers a consumers government that appreciates tax revenues as such leviathan in addition to conventional measures of welfare i e carbon taxes serve the dual purpose of correcting for externalities here global warming or more generally a stock externality from energy use and of raising revenues this government faces either a competitive or a perfectly cartelized supply the major findings are 1 i consumers may benefit from a leviathan government that appropriates some of the monopoly rent by deterring preemption to some extent 2 ii the leviathan motive raises initial taxes and thereby lowers initial emissions but increases the long run stock externality in a play with linear strategies 3 iii there exists a continuum of equilibria in nonlinear markov strategies which are however pareto inefficient compared with the linear strategies 4 iv but in case of a binding resource constraint nonlinear strategies are the only feasible ones

who plays the numbers games in the middle of the day we analyse the increase in sales of pick 3 and pick 4 daily numbers lottery games and other ohio lottery games after ohio introduced midday drawings for the pick 3 and pick 4 games in august 1999 the midday drawings increased pick 3 sales by 5 pick 4 sales by 12 and total lottery sales by 2 based on our analysis of a 36 month panel dataset of ohio lottery sales by zip code midday drawings raise more revenue from the strongly regressive daily numbers games however the introduction of midday drawings does not change the negative income elasticities of demand for numbers games in an economically meaningful manner

on the economics of state lotteries s tate lotteries can be evaluated from either of two perspectives familiar to economists as a consumer commodity or as a source of public revenue l as a commodity the lottery is notable for its broad market penetration and rapid growth sixty percent of the adults in lottery states play at least once in a year the annual growth in real per capita sales in lottery states has averaged 12 percent rising in 1989 dollars from 22 in 1975 to 108 in 1989 as a source of public revenue lotteries account for a rather modest fraction of revenue in states that run them 3 3 percent in 1986 but they are nonetheless one of the most visible state government activities lottery sales exceed those of all other products sold directly by state governments to the public and are larger than all but three major activities of state government education public welfare and highways clotfelter and cook 1989 table 2 5 moreover lotteries are a qualitatively new activity for state governments in that they are a business operated in effect for profit state liquor stores are perhaps the closest analog but they were created to encourage temperate drinking practices and do not engage in the sales promotion and marketing activities that are characteristic of the lotteries lotteries enjoy an honored place in american history as a device for raising funds for public purposes funding for such institutions as the jamestown settlement harvard college and the continental army as well as hundreds of bridges fire houses and schools came from lotteries but after the

job search by employed and unemployed youth analysis of data from the new youth cohort of the national longitudinal survey yields evidence that young unemployed job seekers chose higher levels of search effort as measured by number of methods used and time spent per method and lower reservation wages relative to offered wages than did comparable employed job seekers in 1981 these differences in search choices at least partly explain differences in search outcomes between the two groups unemployed searchers apparently were more likely than employed searchers to gain new employment and the wages they obtained were slightly lower the author argues that the greater search effort by unemployed job seekers is due to the higher costs of search they bear because of foregone earnings

the economics of casino taxation in this article a model of the costs of a casino is developed that focuses on the implications for economic welfare of different taxation schemes for casinos the situation being considered is in a country where casinos cater exclusively to foreign tourists the goal of the country is to determine the maximum amount of taxes that can be extracted from the activities of this sector under different systems of taxation when the price of gambling is set by regulation above its competitive level the economic losses created by excessive investment in the sector can be reduced by taxation a turnover tax on the amount gambled can maximize both tax revenue and the economic welfare of the country due to administrative constraints a number of countries rely on the taxation of the casinos fixed assets or a combination of a turnover tax and a tax on fixed costs the model is applied to the situation in north cyprus the annual economic efficiency loss from its poorly designed tax policies on casino gambling is

field experiments of discrimination in the market place controlled experiments using matched pairs of bogus transactors to test for discrimination in the marketplace have been conducted for over 30 years and have extended across 10 countries significant persistent and pervasive levels of discrimination have been found against non whites and women in labour housing and product markets rates of employment discrimination against non whites in excess of 25 have been measured in australia europe and north america a small number of experiments have also investigated employment discrimination against the disabled in britain and the netherlands and against older applicants in the united states

four formal izable theories of the firm in this essay i define and compare elemental versions of four theories of the firm these elemental theories are distilled from important contributions by hart holmstrom klein williamson and others although these contributions have been widely cited and much discussed i have found it difficult to understand the commonalities distinctions and potential combinations of these seemingly familiar contributions in this essay therefore i attempt to clarify these issues in three steps i begin with informal summaries of the theories then turn to simple but formal statements of each elemental theory and finally nest the four elemental theories in an integrative framework

education s gambling problem earmarked lottery revenues and charitable donations to education i examine the impact that lotteries introduced to support education have on voluntary contributions to education state lotteries and the causes they are introduced to support are highly publicized this provides the opportunity to assess whether donors are crowded out by government spending of which they are almost certainly aware using donor level survey data and nonprofits tax returns i find that donations to education related organizations fall with the introduction of a lottery this result is driven by donors response to the new highly publicized government revenue source rather than a decrease in nonprofit fundraising efforts jel d64 h3 h75

competition between employed and unemployed job applicants swedish evidence we use the swedish applicant database to investigate empirically whether being unemployed per se reduces the probability of getting contacted by a firm all searchers looking for a new job are invited to submit their personal details to this database over the internet since we have access to exactly the same information as the firms we can minimize the problems associated with unobserved heterogeneity our results show that an unemployed applicant faces a lower contact probability than an otherwise identical employed applicant thus supporting the notion that firms view employment status as a signal of productivity

consumer value maximizing sweepstakes and contests abstract sweepstakes and contests are some of the most frequently used promotional tools consumers participating in sweepstakes or contests have an opportunity to win prizes through a random draw the authors examine how commonly used sweepstakes formats that vary in the number of winners and the allocation of the total reward money among the winners affect consumer valuations of the promotion given a fixed amount of reward money the authors examine alternative reward formats based on the promotional objectives consumer risk aversion and degree of subadditivity they test the analytical results using an experimental approach

government borrowing using bonds with randomly determined returns welfare improving randomization in the context of deficit finance abstract we study the problem of a government that wishes to share optimally the burden of deficit finance among agents with differential access to investment opportunities in the presence of private information it is pareto efficient for the government to borrow in a way that amounts to non linear taxation and it must treat agents with access to the best investment opportunities preferentially to keep them in the bond market in addition with private information about access to assets it is often desirable to randomize extraneously the return on the highest yielding government liabilities the optimal government policy is shown to accord well with historical observations and provides insight into why explicit randomization is not often observed in private contracts

the market for sweepstakes this paper studies the market for monopolistically supplied sweepstakes we derive equilibrium demands for fixed prize and variable prize sweepstakes and determine the profit maximizing prize level and pay out ratio respectively it can be profitable to offer each type of sweepstake when there is a large enough number of weighted utility consumers who have constant absolute risk attitudes are strictly averse to small as well as symmetric risks and display longshot preference behaviour moreover for the variable prize sweepstake the supplier will generally find it profitable to combine sweepstakes targeting two smaller populations and offer a single sweepstake to the combined population this implication is corroborated by the recent spate of mergers of smaller state lotteries into larger ones

investigating efficiency in betting markets evidence from the greek 6 49 lotto abstract in this paper we investigate the existence of profit opportunities in the greek market for the 6 49 lotto under the assumption of random number selection we find evidence suggesting that the market is efficient because number selection is found to deviate from randomness we further investigate the existence of profit opportunities due to number unpopularity the evidence suggests that although unpopular numbers exist they are not sufficiently unpopular so as to generate positive expected payoffs

lottery expenditures in canada a regional analysis of determinants and incidence this article examines two issues first it evaluates the statistical significance of a number of socio economic and demographic variables on the level of household lottery expenditures in the six regions of canada while some household characteristics vary in the extent to which they significantly affect the level of lottery expenditures across regions wealth age occupation mother tongue and urban location for example others are significant in every region regional consistency exists in the statistical significance of after tax household income sex and education of the head of household lottery expenditures increase as incomes increase lottery expenditures are significantly lower for female heads of households than for their male counterparts lottery expenditures decline as the education level of the head of household increases second lottery expenditures are found to be regressive although the degree of regressivity is less than for lotteries in the united states

on the job search some empirical evidence from britain abstract this paper considers evidence from the labour force survey concerning job search by employed workers the unconditional probability of observing on the job search is decomposed into the product of two constituent probabilities upon which maximum likelihood estimation is performed the analysis facilitates the identification of who searches and whether search takes place in work or from unemployment temporary or part time employment encourages continued search by men but not women skilled workers search more than the unskilled and demonstrate a preference for employed search inter industry wage relativities encourage search on the job job tenure is a significant determinant of the quality of a job match and the subsequent likelihood that on the job search is undertaken employed job seekers adopt search strategies that are more readily integrated into a working environment

ranking unemployment duration and wages it explores the implication of one central assumption when firms receive multiple acceptable applications they hire the worker who has been unemployed for the least amount of time this assumption ranking is contrasted with the assumption of random hiring no ranking by embodying this assumption in a model of the labour market with job creation destruction and matching the joint behaviour of unemployment the distribution of unemployment durations and wages are characterized the implication that the re employment prospects of employed workers were they to become unemployed are better than those of the currently unemployed appears to have been an important feature of european unemployment experience in the 1980 s this paper examines the effects of the composition of unemployment on wage determination it explores one central assumption when firms receive multiple acceptable applications they hire the worker who has been unemployed for the least amount of time we refer to this assumption as ranking and contrast it throughout to the assumption of random hiring or no ranking by embodying this assumption in a model of the labour market with job creation destruction and matching we characterize the joint behaviour of unemployment the distribution of unemployment durations and wages ranking has a number of important implications first in addition to the obvious result that the exit rate from unemployment is a decreasing function of duration we show that the effect of duration is stronger the higher the rate of unemployment second with the wage depending on the distributions of prospective unemployment durations the presence of long term unemployed per se has little effect on wages third looking at the relation between the wage and the aggregate level of unemployment and comparing ranking to the case of no ranking the wage moves less with the level of unemployment but more with the change in unemployment put simply ranking and no ranking models show exactly the same aggregate unemployment slightly different long run responses of wages to unemployment and sharply different wage dynamics the paper is organized as follows section i characterizes the matching process and derives a matching function based on an urn ball process with vacancies as urns and applications by unemployed workers as balls thus the distribution of applications per vacancy depends on aggregate unemployment and vacancies vacancies with at least one acceptable application are filled when a vacancy receives more than one acceptable application firms use a rule to choose among applicants thus the rule determines who is hired but does not affect the number of hires section ii uses this matching function in a model of the labour market with continual job creation and destruction and characterizes the equilibrium values of unemployment vacancies and hires

an empirical model of employed search unemployed search and nonsearch the 1969 1971 national longitudinal surveys data on young men were used to study the employed worker s choice among employed search unemployed search and not searching for a new job we assume that an unobserved variable search intensity governs this choice such that unemployed search involves a greater intensity than employed search which of course is associated with greater intensity than nonsearch the principal results are that current wages seniority collective bargaining coverage employment outside construction and employment by government are each ceteris paribus negatively associated with search intensity further each of these variables lowers the probability of not searching and raises the probabilities of employed and unemployed job search

unemployment dynamics and duration dependence a major issue in the analysis of unemployment durations concerns distinguishing genuine duration dependence of the exit rate out of unemployment from unobserved heterogeneity we present a method for the nonparametric estimation of both phenomena designed to be applicable to time series data on aggregate outflows from different duration classes the model explicitly takes into account that individual exit rates are affected by the business cycle and by seasonal effects the method is applied to u s data we find diverging duration effects among black and white individuals however except for white males duration dependence is dominated by unobserved heterogeneity

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

improving incentives in unemployment insurance a review of recent research abstract this paper provides a review of the recent literature on how incentives in unemployment insurance can be improved we are particularly concerned with three instruments i e the duration of benefit payments or more generally the time sequencing of benefits monitoring in conjunction with sanctions and workfare our reading of the theoretical literature is that the case for imposing a penalty on less active job search is fairly solid a growing number of empirical studies including randomized experiments are in line with this conclusion

the effect of power imbalances on incentives to make non contractible investments we use an experiment to study the effect of ex post sharing rules on relationship specific investments in an incomplete contracting context we find that no power structure can induce first best investments and that equally productive partners reach more efficient outcomes with a balanced power structure i e equal sharing of returns than with an asymmetric one in addition we find evidence for behavioural effects partners make higher investments and reach higher efficiency levels than own payoff maximisation would suggest this behaviour is in line with a model where decision makers care about social efficiency it is not consistent with inequity averse preferences
