efficient and durable decision rules with incomplete information we compare six concepts of efficiency for economies with incomplete information depending on the stage at which individuals welfare is evaluated and on whether incentive constraints are recognized an example is shown in which an incentive efficient decision rule may be unanimously rejected by the individuals in the economy we define durable decision rules which can resist such unanimous rejection and show that efficient durable decision rules exist

the impact of the london olympics announcement on property prices this study estimates the impact of the london 2012 olympics announcement on property prices using a self constructed dataset of a sample of property transactions it is estimated that properties in host boroughs are sold between 2 1 and 3 3 per cent higher depending on the definition of the impact area a similar investigation based on radius rings suggests that properties up to three miles away from the main olympic stadium sell for 5 per cent higher it is estimated that the overall impact on the price of properties in host boroughs amounts to 1 4 billion having substantial social and financial implications for existing residents

distinctively different a new approach to valuing architectural amenities we propose a method to estimate the capitalized value of the architectural design quality of a neighbourhood our economic design premium is identified by spatially differentiating property prices and design quality within neighbourhoods and comparing the differences across neighbourhoods we apply our method to 47 conservation area neighbourhoods in england in which we analyse around 7900 property transactions and interview more than 500 residents we find a capitalization effect of about 25 4 38 7k associated with a one step increase on a five step scale ranging from not at all distinctive to very distinctive our results suggest that this effect is at least partially driven by an architectural externality

mechanism design with incomplete information a solution to the implementation problem the main result of this paper is that the multiple equilibrium problem in mechanism design can be avoided in private value models if agents do not use weakly dominated strategies in equilibrium we show that in such settings any incentive compatible allocation can be made the unique equilibrium outcome to a mechanism we derive a general necessary condition for unique implementation which implies that the positive result for private value models applies with considerably less generality to common value settings and to situations in which an agent s information does not index the agent s preferences

local economic gains from primary election spending this article asks how government and private consumption spending affect earnings in service sectors to do this we exploit the variation across states and time in the money spent while campaigning for a party s presidential primary nomination we create a novel data set combining the date each state held its primary from 1976 to 2008 the date in each election cycle in which only one candidate remained and quarterly state earnings by sector using an instrumental variable strategy we find that hosting a primary election increases earnings particularly in the retail and accommodation sectors these results remain consistent when using data on primary campaign expenditures across states in the 2004 and 2008 elections

implementation in differential information economies abstract we consider the problem of implementation of social choice correspondences in differential information economies we provide necessary conditions for implementation and slightly stronger conditions which are sufficient to guarantee implementation

news shocks in the data olympic games and their macroeconomic effects we examine the macroeconomic effects of bidding for the olympic games using panel data for 188 countries during the period 1950 2009 our findings confirm that economies react to news shocks investment consumption and output significantly increase 9 to 7 years before the actual event in bidding countries hosting countries also experience significant increases in investment consumption and output 5 to 2 years before the hosting of the games mapping the olympics into a macroeconomic model we show that we can match our empirical findings if we assume that an olympic bid represents news about increases in government investment

going for the gold the economics of the olympics in summer 2016 the eyes of the world will turn to rio de janeiro as it hosts the games of the xxxi olympiad better known as the summer olympics unfortunately the price tag of well over 10 billion for the event is adding to the already considerable strain on government budgets in brazil faced with a nasty recession cuts in public services and rising unemployment throngs of brazilians have turned out to protest what is seen as wasteful spending and a misallocation of resources on the olympics throw in the growing threat of the zika virus and brazil may end up with larger crowds of agitators protesting the government than of sports fans cheering on the athletes but are these complaints about olympic spending justified the quadrennial summer olympic games is one of the world s premier sporting events with over 10 000 athletes representing 204 countries 300 individual events in 28 different sports over 10 million tickets sold to spectators and a worldwide television audience in the billions on a somewhat smaller scale the most recent winter olympic games held in 2014 in sochi russia welcomed nearly 3 000 athletes from 88 countries to compete in 98 events in 15 disciplines while generating large revenues and massive television ratings while most viewers tune in to watch the competition among the athletes the battle among cities to be selected to host these events can be just as fierce although bidding cities have numerous reasons for wanting to host none seems more prevalent than the desire for an economic windfall in this paper we explore the costs and

continuous and feasible implementation of rational expectations lindahl allocations abstract in this paper we consider bayesian implementation of rational expectations lindahl allocations for economic environments with public goods when agents are incompletely informed about environments we construct a continuous and feasible mechanism whose bayesian equilibrium allocations coincide with rational expectations lindahl allocations we not only allow the types of individuals to be unknown but also allow both the preferences and the initial endowments to be unknown to the designer in addition we allow some types of boundary equilibrium allocations and a continuous information structure journal of economic literatureclassification number c72 d71 d82 h41

the price of victory the impact of the olympic games on residential real estate markets the olympic games have come to be viewed as an unprecedented opportunity to leverage a short term event into a long term positive legacy although the olympics are assumed to yield economic benefits there has been no rigorous analysis of the impact of hosting on residential real estate markets utilising a substantial dataset for six host cities and comparable cities between 1984 and 2000 this paper employs an adjusted interrupted time series approach to estimate the house price impacts of hosting the olympic games the results suggest that the olympics are not a one size fits all economic development strategy and that potential outcomes are dependent on a number of factors including the co ordination of planning and olympic related development and the relative scale of the total olympic investment

crop yield skewness under law of the minimum technology no satisfactory motivation has been forwarded in favor of any crop yield distribution including the normal this article explores the foundations of yield distributions for the law of the minimum resource constraint technology at the plot level of analysis with independent identical uniform resource availability distributions the yield skew is positive whereas it is negative whenever the distributions are normal simulations show how asymmetries in resource availabilities determine skewness it is suggested that a negative yield skew occurs whenever production is tightly controlled so that the left tails of some resources availabilities distributions are thin irrigation may increase yield skewness copyright 2009 oxford university press

are crop yields normally distributed the evidence for nonnormality of crop yields is reassessed three methodological problems are identified in typical yield distribution analyses i misspecification of the nonrandom components of yield distributions ii missreporting of statistical significance and iii use of aggregate timeseries ats data to represent farm level yield distributions one or more of these problems infect virtually all evidence against normality to date the positive contribution of the article is a set of principles that must be followed in any valid investigation of yield normality

implementation in economic environments with incomplete information the use of multi stage games abstract this paper shows that in economic environments with incomplete information incentive compatibility and a preference reversal condition are sufficient for implementation in sequential equilibrium journal of economic literature classification numbers c72 d71 d82

compensating differentials and the social benefits of the nfl abstract we use hedonic rent and wage equations to measure compensating differentials in central cities and metropolitan areas with franchises of the national football league rents are about 8 percent higher in the central cities but this impact may not carry over to broader geographical areas wages are about 2 percent lower in areas with teams but the standard error on this parameter is large the central city results indicate that sports franchises appear to be a public good once these quality of life benefits are included in the calculus the large public expenditure on new stadiums appears to be a good investment for cities and their residents

consumption benefits of national hockey league game trips estimated from revealed and stated preference demand data this paper examines the demand for hockey game trips among metropolitan and nonmetropolitan residents of alberta canada using data on both revealed and stated preference game trip behavior from a telephone survey conducted throughout alberta we estimate the effect of ticket prices team quality arena amenities and capacity on the latent demand for national hockey league hockey games we nd that lower ticket prices higher team quality and additional capacity encourage attendance in the status quo scenario consumer surplus per game is 50 for those who had attended hockey games and about 50 less for those who had not attended games exploiting the stated preference data we develop a number of other consumer surplus estimates we also include travel costs in the estimation of the demand function and estimate the full value of the game trip considering both ticket prices and travel costs sold out arenas in calgary and edmonton generate annual consumption bene ts of 40 and 35 million when only ticket prices are used to calculate consumer surplus i e excluding travel costs considering the full price consumer surplus for the calgary flames of 103 per game trip the annual consumption bene ts may be as high as 82 million jel r22 l83 d61

nash implementation using undominated strategies we study the problem of implementing social choice correspondences using the concept of undominated nash equilibrium i e nash equilibrium in which no one uses a weakly dominated strategy we show that this mild refinement of nash equilibrium has a dramatic impact on the set of implementable correspondences our main result is that if there are at least three agents in the society then any correspondence which satisfies the usual no veto power condition is implementable unless some agents are completely indifferent over all possible outcomes many common welfare criteria such as the pareto correspondence and several familiar voting rules such as majority and plurality rules satisfy our conditions this possibility result stands in sharp contrast to the more restrictive findings with implementation in either nash equilibrium or subgame perfect equilibrium we present several examples to illustrate the difference between undominated nash implementation and implementation with alternative solution concepts

a direct test of the homevoter hypothesis abstract we propose a methodology that facilitates a direct test of the homevoter hypothesis which posits that homeowners vote in favor of public projects they perceive increase residential property values and against those that do not first we estimate how pre referendum events that signal a higher probability that the public project will be undertaken impact local residential property values before the referendum is held these pre referendum impacts are considered noisy signals to homeowners about the market s assessment of the net marginal benefits of the project second we aggregate these market signals to the precinct level and relate them to precinct level voting results concerning the proposed project we apply this two step approach to the 2004 referendum in arlington texas for a publicly subsidized stadium for the nfl dallas cowboys the analysis supports the homevoter hypothesis and establishes a possible methodology for future evaluations in this small but growing empirical literature

a winning proposition the economic impact of successful national football league franchises it was the best of times and it was the worst of times this classic phrase could be used to describe the period of 1990 through 1993 for fans of the buffalo bills the bills performed well enough to win the american football conference championship four consecutive years but each year the team s season ended with a super bowl defeat the purpose of this study is to determine if fans of successful but not world champion sport teams like the buffalo bills experience economic benefits in conjunction with their team s successes coates and humphreys 2002 examined whether a sports team winning a championship had a positive effect on the real per capita personal income of the local metropolitan area despite examining various measures of success across several different sports 1 coates and humphreys found that the local national football league nfl team winning the super bowl was the only variable that had a significant positive effect on income although matheson 2006 shows evidence contradicting the findings coates and humphreys results are interesting when considered in the context of other similar studies that fail to find a positive effect from the presence of the teams in the city coates and humphreys 1999 2003 the building of stadia for the teams coates and humphreys 1999 or the presence of major events like the super bowl or world cup baade and matheson 2000 2004 matheson and baade 2006 on local income in this paper we use a psychological framework to provide a rationale for the increased economic well being associated with a super bowl victory additionally we rely on the psychological literature and argue that the economic benefits of a winning team should extend beyond just the championship team to the cities of teams that experience seasonal success to examine whether a winning effect can be extended to all teams in the league and is not limited to just the super bowl champion we include the winning percentage of the local nfl team although lacking a formal model the psychological literature suggests multiple individual level processes that may account for the economic impact of winning percentage to test whether the effect is based on increased consumption or increased productivity we estimate our models on the real wage income per capita as well as personal income additionally because the econometric model is a dynamic panel series model a model that can exhibit substantial bias in the coefficients judson and owen 1999 we use the method of arellano and bond 1991 to correct for bias this method also provides insight in regard to the directionality of the winning percentage and personal income relationship specifically that winning percentage drives changes in personal income as opposed to changes in personal income impacting winning percentage in the arellano bond estimations winning percentage is treated as endogenous meaning within the system while the remaining variables are treated as being exogenous as an additional further check we reestimate the model including team salary if the direction of causation flows from income to winning it would be indicated by increases in the coefficient on payroll for the team the results show that even after including team salaries in the model winning percentage still positively impacts income i psychological impact of sport team s success research has consistently demonstrated that people go to great lengths to publicly identify with winning sport teams cialdini et al 1976 cialdini and richardson 1980 end 2001 joinson 2000 wann and branscombe 1990 this tendency to bask in the reflected glory cialdini et al 1976 is related to event specific success a team s victory and global success winning percentage qualifying for play offs etc specifically end et al 2002 found that when sport fans were asked to identify their favorite teams the teams with which they identified had an average winning percentage significantly greater than 50

crop insurance valuation under alternative yield distributions considerable disagreement exists about the most appropriate characterization of farm level yield distributions yet the economic importance of alternative yield distribution specifications on crop insurance valuation has not been well documented the results of this study demonstrate that large differences in expected payouts from popular crop insurance products can arise solely from the parameterization chosen to represent yield distributions the results suggest that the frequently unexamined yield distribution specification may lead to economically significant errors in crop insurance policy rating and assessment of expected payouts from policies

why are stabilizations delayed when a stabilization has significant distributional implications e g tax increases to eliminate a large budget deficit socioeconomic groups may attempt to shift the burden of stabilization onto other groups the process leading to stabilization becomes a war of attrition each group attempting to wait the others out and stabilization occurring only when one group concedes and bears a disproportionate share of the burden the authors solve for the expected time of stabilization in a model of rational delay and relate it to several political and economic variables they motivate this approach and its results by comparison to historical and current episodes copyright 1991 by american economic association

robust implementation in direct mechanisms a social choice function is robustly implementable if there is a mechanism under which the process of iteratively eliminating strictly dominated messages lead to outcomes that agree with the social choice function for all beliefs at every type profile in an interdependent value environment with single crossing preferences we identify a contraction property on the preferences which together with strict ex post incentive compatibility is sufficient to guarantee robust implementation in the direct mechanism strict ex post incentive compatibility and the contraction property are also necessary for robust implementation in any mechanism including indirect ones the contraction property requires that the interdependence is not too high in a linear signal model the contraction property is equivalent to an interdependence matrix having all eigenvalues smaller than one

sports led tourism spatial displacement and hotel demand we analyze the relationship between professional sports events and concerts held in la s staples center and nearby hotel performance government led economic redevelopment projects often envision sports facilities as tourist magnets little evidence exists supporting links between sporting events and hotel demand an empirical analysis exploiting exogenous daily variation in the timing of games and concerts from 2002 to 2017 shows a small positive impact on room revenue at hotels within one mile and larger room revenue decrease at hotels located one to 4 miles away the overall impact on hotel room revenue and rooms rented was not positive nearby hotel room rates increased during nba and nhl work stoppages the city granted four new hotels built very near the arena exemptions from occupancy taxes for 20 25 years these exemptions reduced hotel tax revenues by a minimum of 4 5 million annually and may not have been needed to spur new hotel development jel h26 h71 z28

are crop yields normally distributed a reexamination this article demonstrates that normality test procedures that include individual detrending of short term panel data can severely reduce the power of normality tests and strongly bias normality tests in a type ii direction an alternative error component implicit detrending procedure is suggested that demonstrates higher power for the distributions examined both procedures are applied to a large data set with normality of yield residuals being rejected assuming normality is shown to reduce potential premium rates for a large number of producers in an existing crop insurance product

globalization and the confidence game abstract we show that governments in developing countries have an incentive to play the confidence game wherein the need to win the confidence of the international capital market can actually prevent a country from following otherwise sensible policies and force it to follow policies that it would normally consider perverse this incentive arises because of a combination of a conformity bias and good news bias in governmental decision making in an open economy which results in inefficient outcomes which increases rather than decreases the threat of devaluation while institutions that encourage greater transparency and the public revelation of information may often mitigate this inefficiency on some occasions increased transparency may even exacerbate the inefficiency

regulating an oligopoly with unknown costs abstract we examine the problem of a planner who is regulating an oligopoly with unknown costs we provide a complete characterization of the optimal mechanism which takes the following simple form firm s which report low costs produce together the first best output corresponding to this low cost and firm s which report high costs produce nothing when all firms report high costs only the ex ante least efficient firm produces the entire output and all the other firms produce nothing we show that under mild conditions as the number of firms increases the planner attains the same welfare level as if he had complete information of low cost

compensating differentials and the social benefits of the nfl a comment abstract in a recent article in this journal carlino and coulson g carlino n e coulson compensating differentials and the social benefits of the nfl journal of urban economics 56 1 2004 25 50 report evidence that the presence of an nfl franchise in a city raises rents in the central part of the city by about 8 we re estimate their model using several reasonable alternative specifications and find that their results are not robust to these changes the presence of an nfl franchise does not appear to increase rents for center city apartments because their results are not robust to alternative model specifications they should not be used to justify public spending for professional sports facilities

new estimates of quality of life in urban areas implicit markets capture compensation for intraurban and interregional differe nces in amenities and yield differences in housing prices and wages these pecuniary differences become preference based weights in a qual ity of life index hedonic equations are estimated using microdata fr om the 1980 census and assembled county based amenity data on climati c environmental and urban conditions ranking of 253 urban counties reveals substantial variation within as well as among the 185 urba n areas the quality of life differences across counties within one s msa is almost one half of the difference between the top and bottom ranked counties in the nation copyright 1988 by american economic association

wages rents and the quality of life this study focuses on the role of wages and rents in allocating workers to locations with various quantities of amenities the theory demonstrates that if the amenity is also productive then the sign of the wage gradient is unclear while the rent gradient is positive the theory is extended to include the housing market and nontraded goods these extensions require little modification of the conclusion the empirical work on wages shows that the regional wage differences can be explained largely by these local attributes with the use of site price data implicit prices are estimated and quality of life rankings for the cities are computed

a note on feasible implementations abstract this paper is concerned with the problem of individually feasible outcomes in decentralized allocation mechanisms we consider a well known mechanism which achieves efficient allocations in equilibrium this mechanism however may leave agents bankrupt if they fail to reach equilibrium it is shown that the bankruptcy problem can be avoided if a voting stage is added to the original mechanism

the erosion of colonial trade linkages after independence high trade between countries with colonial ties may be explained by government policies that establish preferential access or as a consequence of networks formed through social interactions using bilateral trade data from 1948 to 2003 we examine the eect of independence on post colonial trade the severing of formal colonial relations can lead to an immediate reduction in trade as preferential access is eliminated as well as a gradual reduction corresponding to the deterioration of trading networks our results reveal that independence reduces colonial trade with its colonizer metropole the reduction cumulates over a 30 year period and the disruption is particularly severe for hostile separations we also find that overall colonial trade falls subsequent to independence but to a lesser extent than trade with the metropole

rational expectations information acquisition and competitive bidding most rational expectations market equilibrium models are not models of price formation and naive mechanisms leading to such equilibria can be severely manipulable in this paper a bidding model is developed which has the market like features that bidders act as price takers and that prices convey information higher equilibrium prices convey more favorable information about the quality of the objects being sold than do lower prices bidders can benefit from trading only if they have a transactions motive or if they have access to inside information apart from exceptional cases prices are not fully revealing a two stage model is developed in which bidders may acquire information at a cost before bidding and for which the equilibrium price is fully revealing resolving a well known paradox

efficient allocation with continuous quantities abstract the inefficiency of allocation mechanisms in the presence of bilateral asymmetric information is reconsidered in an environment with continuous quantities the result of myerson and satterthwaite is proved in this environment under the condition that zero trade is efficient if the highest cost seller or the lowest value buyer appears in addition if this condition fails there may exist mechanisms implementing efficient allocations the problem of hidden endowments is considered where any agent may be either a buyer or seller depending on the realization of the privately observed information in this environment it is often possible to arrange efficient trades ex ante asymmetries rather than interim asymmetries tend to prevent efficient allocations

a nonparametric efficient public good decision mechanism undominated bayesian implementation abstract it is known that with incomplete information there are bayesian mechanisms that undertake public projects achieving ex post efficiency and budget balance however there are two shortcomings in these mechanisms first the mechanism designer is required to know the agents prior beliefs which is quite demanding second the mechanism may possess multiple equilibria including undesirable ones this paper presents a bayesian mechanism that is nonparametric in that the mechanism designer cannot incorporate any information other than that received from the agents moreover at all undominated bayesian equilibria of the mechanism the public project is undertaken efficiently and budget is balanced journal of economic literature classification numbers c72 d78 d82

subgame perfect implementation this paper examines the use of stage mechanisms in implementation problems and provides a partial characterization of the set of subgam e perfect implementable choice rules it is shown that in many economic environments virtually an y choice rule can be implemented to illustrate the power of this approach the paper discusses a number of models in which it is possible to implement the first best although it wouldn t have been possible to do so without using stage mechanisms the diversity of these models suggests that subgame perfect implementation may find wide application copyright 1988 by the econometric society

the olympic effect why should countries offer to host costly mega events such as the olympic games we show that hosting a mega event increases exports this effect is statistically robust permanent and large trade is over 20 higher for host countries interestingly unsuccessful bids to host the olympics have a similar impact on exports we conclude that the olympic effect on trade is attributable to the signal a country sends when bidding to host the games rather than the act of actually holding a mega event we develop an appropriate formal model and derive conditions under which liberalising countries will signal through a mega event bid

uncertainty resolution private information aggregation and the cournot competitive limit a cournot model of oligopoly in which otherwise identical firms have private differential information about the common cost of production and a shared but unknown demand curve is examined a bayesian equilibrium of the corresponding game of incomplete information is solved for explicitly and analysed in the symmetric equilibrium different firms produce at different output levels because they have different information because the information individual firms have is random total output and hence market price is also random for any finite number of firms the main result of the paper relates to the asymptotic properties of the equilibrium when the number of firms becomes large under fairly general conditions on the joint distribution of demand and individual firms information about demand the random equilibrium price converges almost surely to a constant in the limit more importantly this price equals the perfectly competitive price in other words in large markets even if no firm knows the true market demand curve and firms are not price takers and do not use price as a signal to improve their information the competitive price will prevail with certainty in the limit aggregate outcomes are as if all firms shared their private information with each other

pareto optima and competitive equilibria with adverse selection and moral hazard this paper explores the extent to which standard general equilibrium analysis of pareto optima and of competitive equilibria can be applied to environments with moral hazard and adverse selection problems allowing for lotteries contracts with random components we first establish that an adverse selection insurance economy a moral hazard insurance economy a signaling economy and a private information labor market economy are all special cases of a simple general structure we then show that techniques for characterizing pareto optimal contracts as solutions to concave programming problems are useful and nice and appear to be broadly applicable allowing for lotteries we show how to characterize the optimal allocations for the adverse selection insurance and labor market economies we then show that standard existence and optimality theorems for competitive equilibria apply in the linear space containing lotteries if agents with characteristics which are distinct and privately observed at the time of initial trading enter the economy wide resource constraints in a homogeneous way other kinds of diversity are not critical for economies with moral hazard which satisfy the homogeneity condition competitive contract markets single out a subset of the optima and thus can be consistent with apparent unemployment and with a random allocation of labor supplied though all households are averse to risk the adverse selection insurance and signaling economies however do not satisfy the homogeneity condition and are difficult to decentralize efficiently with a price system

the impacts of temporary but anticipated tourism spending an application to the glasgow 2014 commonwealth games an extensive literature attempts to identify the economic impact of tourism expenditure while input output methods have been widely applied these may not always be appropriate for such applications and there is a growing use of more flexible computable general equilibrium cge approaches this paper uses a multi period scottish cge model to estimate the system wide effects of the temporary tourism expenditure related to the glasgow 2014 commonwealth games we quantify the sensitivity of our results to model specification focusing in particular on how investment and consumption decisions are made and shifted over time to accommodate the temporary tourism shock as part of this analysis we identify the pre announcement period that optimises the present value of the economic impact whilst the empirical results apply to a specific event our results have implications for similar analyses applied to mega events and other temporary phenomena affecting tourism expenditure such as terrorism attacks or epidemics

the effect of professional sports on the earnings of individuals evidence from microeconomic data this article examines the impact of professional sports franchises in labour markets using data from the march supplement to the current population survey cps for workers employed in specific occupational groups in all large us cities from 1983 to 2002 results from a standard wage model suggest that professional football franchises increase average hourly and weekly earnings of males employed in these occupations but professional baseball franchises reduce them these results support growing evidence that professional sports affect labour markets however the mixed nature of the association between sport and earnings provides little economic justification for government subsidies for professional sport

local labor markets and natural resources a synthesis of the literature a primary way that natural resources affect a locality is through the demand for labor with greater extraction requiring more workers shifts in labor demand can be measured through changes in employment and earnings the main labor market outcomes or through changes in the population and income more generally these changes may spillover into the nonresource economy leading to greater overall effects or possibly crowd out be spread unequally across the population thereby altering the distribution of income and the poverty rate or influence educational attainment as people choose between additional schooling and work in this review the literature linking natural resources to local labor markets is synthesized by organizing existing studies according to their resource measurement and the outcomes that they consider this synthesis provides an accessible guide to a literature that has boomed in recent years it also identifies promising avenues for future research and lays a foundation to further generalize the evidence through an eventual meta analysis

optimal incentive contracts with multiple agents abstract a setting in which a single principal contracts with two agents who possess perfect private information about their own productivity is considered with correlated productivities each agent s private information also provides a signal about the other agent s productivity in contrast to the setting in which there is only one agent it is shown that such private information may be of no value to the agents it is only if the agents are risk averse that their private information may allow them to command rents moreover when the agents are constrained only to reveal their private information truthfully as a nash equilibrium the pareto optimal incentive scheme may induce the agents to adopt strategies other than truth telling this leads to the consideration of truth telling equilibria that are not pareto dominated in the subgame played by the agents among all such equilibria the one preferred by the principal restricts one agent to tell the truth as a dominant strategy and the other as a nash response to truth

on the economic impact of international sport events microevidence from survey data at the euro 2008 using firm level data for more than 700 swiss hotels and restaurants we evaluate the economic impact of the euro 2008 soccer championship in switzerland although aggregated macrodata do not reveal any sizable economic impact we report an overall negative effect based on the surveyed companies notably the reported effects of the individual firms are very heterogeneous for instance hotels in cities benefitted from the tournament as they were able to raise prices and thereby increase sales looking at the long run impact only a small fraction of companies do believe in a positive effect interestingly this outlook does not depend on realized sales but on the guest structure

does the world cup get the economic ball rolling evidence from a synthetic control approach abstract in this paper we analyze the impact of hosting the fifa soccer world cup on gdp per capita in a worldwide sample of countries using a transparent statistical methodology for data driven case studies the synthetic control method using country level annual data covering all events occurring in the period between 1978 argentina and 2006 germany we show that the estimated average treatment effect was either zero or negative for all but one of the countries analyzed our results therefore support the general claim that world cups are not statistically associated to development and economic growth

fiscal policies and the choice of exchange rate regime a common argument against either a monetary union or a regime or a fixed exchange rates is that they preclude flexible use of the inflation tax the authors address this point of view by comparing three alternative exchange rate regimes a pure float an ems regime in which the exchange rate is fixed but can be realigned and a monetary union the authors model the three regimes as alternative commitments on future seigniorage policies this approac h suggests that it is not possible to pareto rank the three regimes o n the other hand the authors provide intuitive conditions under which each of the systems is superior to the others copyright 1993 by royal economic society

toward a normative theory of crop yield skewness while the preponderance of empirical studies point to negative crop yield skewness in a wide variety of contexts the literature provides few clear insights on why this is so the purpose of this paper is to make three points on the matter we show formally that statistical laws on aggregates do not suggest a normal yield distribution we explain that whenever the weather conditioned mean yield has diminishing marginal product then there is a disposition toward negative skewness in aggregate yields this is because a high marginal product in bad weather states stretches out the left tail of the yield distribution relative to that of the weather distribution turning to disaggregated yields we decompose unconditional skewness into weather conditioned skewness plus two other terms and study each in turn

large sport events and unemployment the case of the 2006 soccer world cup in germany this study analyses on the basis of a multivariate analysis ex post the effects on the jobs market of a soccer world cup in this case the 2006 world cup held in germany in addition to three methods already used for other analyses in studies of sporting events an extended difference in difference estimate is used in order to compare the development of the numbers of unemployed in the 12 world cup venues with the development of the numbers of unemployed in 63 other german cities the results demonstrate that in none of the respective match venues did the effect of the sporting event on unemployment differ significantly from zero

collusion in auctions with externalities in standard auctions collusion among buyers eliminates bidding competition despite informational asymmetries collusion can however be imperfect when the situation involves externalities among buyers that is when a buyer is worse off if one rival wins the goon rather than if nobody gets it for intermediate values of the externality and under various objective functions the seller finds it optimal to design an auction that leads in equilibrium to a collusive outcome that is ex post inefficient for the group of buyers an ex ante incentive efficient collusion mechanism for the buyers is characterized in this situation

spatio temporal modeling of agricultural yield data with an application to pricing crop insurance contracts this article presents a statistical model of agricultural yield data based on a set of hierarchical bayesian models that allows joint modeling of temporal and spatial autocorrelation this method captures a comprehensive range of the various uncertainties involved in predicting crop insurance premium rates as opposed to the more traditional ad hoc two stage methods that are typically based on independent estimation and prediction a panel data set of county average yield data was analyzed for 290 counties in the state of parana brazil for the period of 1990 through 2002 posterior predictive criteria are used to evaluate different model specifications this article provides substantial improvements in the statistical and actuarial methods often applied to the calculation of insurance premium rates these improvements are especially relevant to situations where data are limited

capital account liberalization as a signal the authors present a model in which a government s current capital control policy signals future policies controls on capital outflows evolve in response to news on technology conditional on government attitudes toward taxation of capital when there is uncertainty over governmental types a policy of liberal capital outflows sends a favorable signal that may trigger a capital inflow this prediction is consistent with the experience of several countries that have liberalized their capital accounts copyright 1997 by american economic association

assessing the olympic games the economic impact and beyond this study reviews the literature on the evaluation of the olympic games within the broader framework of their significance as cultural assets and opportunities for endogenous growth and sustainable development of the host city the study reviews the main approaches to the economic assessment of the games from the point of view of the underlying economic concepts and methodologies as well as of the empirical results obtained it focuses on the effects that are measured and on those which even though important are generally neglected the methodologies utilized for the quantitative assessments of the games are reviewed with special emphasis on impact and cost benefit analysis both on ex ante and ex post basis the studies surveyed are analysed from the point of view of different sets of effects on the host city and for a limited number of cases on the host country while the major focus is on hosting the summer olympics some attention is also paid to the bidding cities the winter olympics and the paralympics the general findings appear to be controversial with some hints of positive overall effects but also with a well documented tendency to exaggerate the benefits and underestimate the costs of holding the games in the ex ante versus the ex post studies the survey finally suggests that ex post cross country econometric studies tend to catch sizable differential and persistent benefits ignored by individual studies especially on macroeconomic and trade variables

the economics of sports facilities and their communities since the 1950s taxpayers have been the primary investors in stadia built for the use of privately owned professional sports teams team owners have argued that sports facilities boost local economic activity however economic reasoning and empirical evidence suggest the opposite public support for stadia is also driven by demand for community image and owners of sports teams supply a scarce input into image enhancement participation in the major league for which they have been able to extract monopoly rents from dispersed taxpayers we suggest reforms to dissipate the monopoly sports leagues exercise when negotiating with host communities for their teams

pareto efficiency and weighted majority rules we consider the design of decision rules in an environment with two alternatives independent private values and no monetary transfers the utilitarian rule subject to incentive compatibility constraints is a weighted majority rule where agents weights correspond to expected gains given that their favorite alternative is chosen it is shown that a rule is interim incentive efficient if and only if it is a weighted majority rule and we characterize those weighted majority rules that are ex ante incentive efficient we also discuss efficiency in the class of anonymous mechanisms and the stability of weighted majority rules
