testing for price anomalies in real estate auctions this paper reports on the results of an auction sale of 83 condominium apartment units in new jersey at the auction every unit was hammered down but unknown to the 2 348 registered bidders 40 of the sales fell through prices in the subsequent sale of condominium units in face to face negotiations resulted in identical units selling for 13 less than they fetched at auction and the discount was largest for those units hammered down early in the auction these results are inconsistent with the usual predictions from the theory of common value auctions and suggest that uninformed bidders in this auction may have been the subject of a winner s curse which generated considerable profit for the seller this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from ano this abstract was borrowed from another version of this item

elections coalitions and legislative outcomes predictions of electoral behavior in a multiparty setting should be a function of the voters beliefs about how parties will perform following an election similarly party behavior in a legislature should be a function of electoral promises and rewards we develop a multistage game theoretic model of three party competition under proportional representation the final policy outcome of the game is generated by a noncooperative bargaining game between the parties in the elected legislature this game is essentially defined by the vote shares each party receives in the general election and the parties electoral policy positions at the electoral stage parties and voters are strategic in that they take account of the legislative implications of any electoral outcome we solve for equilibrium electoral positions by the parties and final policy outcomes

the declining price anomaly abstract data from wine auctions indicate that identical products sold sequentially typically follow a decreasing pattern of prices known as the declining price anomaly this is explained for both first and second price auctions by appealing to risk averse bidders earlier bids are then equal to expected later prices plus a risk premium associated with the risky future price we show that this logic rests on the assumption of nondecreasing absolute risk aversion which is necessary for pure strategy equilibrium bidding functions to exist thus decreasing absolute risk aversion implies ex post inefficiency with positive probability data from wine auctions are used to confirm the existence of the declining price anomaly journal of economic literature classification numbers d43 d44 d81 d82 l81

incentives to cultivate favored minorities under alternative electoral systems a simple model is used to compare under different electoral systems the incentives for candidates to create inequalities among otherwise homogeneous voters by making campaign promises that favor small groups rather than appealing equally to all voters in this game model each candidate generates offers for voters independently out of a distribution that is chosen by the candidate subject only to the constraints that offers must be nonnegative and have mean 1 symmetric equilibria with sincere voting are analyzed for two candidate elections and for multicandidate elections under rank scoring rules approval voting and single transferable vote voting rules that can guarantee representation for minorities in multiseat elections generate in this model the most severely unequal campaign promises

partial pooling at the reserve price in auctions with resale opportunities abstract two features common to many auctions are the use of reserve prices and the existence of secondary markets for the goods being sold even in simple symmetric settings the combination of these features can preclude existence of an equilibrium in symmetric separating bidding strategies with a reserve price sufficiently far below the maximum endogenous valuation a symmetric equilibrium still exists but with some types pooling at the reserve the optimal reserve price depends not only on the joint distribution of bidders information before and after the auction but also on how surplus is divided in the secondary market journal of economic literature classification numbers d44 c7 l1 d82

equilibrium reserve prices in sequential ascending auctions abstract we study a model where bidders have perfectly correlated valuations for two goods sold sequentially in two ascending price auctions the seller sets a reserve price before the beginning of each auction despite the lack of commitment by the seller we characterize an equilibrium and study its properties strategic non disclosure of information takes the form of non participation in the early auction by low valuation bidders while high valuation bidders bid up to their true valuations some buyers who would profitably buy at the reserve price refrain from participating in order to decrease the second auction reserve price

how auctions work for wine and art interview auctioneers and even to buy a little wine in the meantime i have also had the opportunity with john abowd 1988 to observe and collect data on the auction sale of impressionist and contemporary paintings this paper reports on some of the empirical regularities that i and others have observed in the actual operation of the auction markets for these items in view of the rich and diverse array of theoretical literature on auctions it seems high time economists began to spell out precisely what facts it is meant to explain 2

political parties and the size of government in multiparty legislatures examining cross country and panel data evidence this article tests the effect of an increase in the number of represented political parties and the size of the majority party on the size of government proxied by central government expenditure as a percentage of gdp in multiparty legislatures the author argues that an increase in the number of represented parties leads to higher central government expenditure conversely as the size of the majority party grows from a bare minimum majority to above the supermajority level it has a nonlinear specifically cube effect on central government expenditure panel data on central government expenditure from 110 countries are used to test these arguments the results corroborate the theoretical claims and are robust in regression models where fixed effects were introduced and endogeneity was corrected finally an increase in the number of represented parties leads to higher government spending on subsidies and transfers but to lower spending on public goods

bayesian inference for comparative research rv egression analysis in comparative research suffers from two distinct problems of statistical inference first because the data constitute all the available observations from a population conventional inference based on the long run behavior of a repeatable data mechanism is not appropriate second the small and collinear data sets of comparative research yield imprecise estimates of the effects of explanatory variables we describe a bayesian approach to statistical inference that provides a unified solution to these two problems this approach is illustrated in a comparative analysis of unionization a widely used tool in quantitative comparative politics is the linear regression model estimating relationships between institutional and economic variables observed for a set of countries constituting some population of interest a brief survey of recent comparative research finds no shortage of work of this type for instance remmer 1991 identifies economic crisis as a source of electoral volatility in latin american countries in the 1980s robertson 1990 presents evidence that institutions moderating the transaction costs of negotiations between capital and labor reduce industrial conflict and golden 1993 finds that union wage moderation in industrialized democracies results from coordinated collective bargaining although the methodological advantages are well documented jackman 1985 we identify two distinct problems of statistical inference endemic to this type of quantitative comparative research first because the data constitute all the available observations from a population conventional inference based on the long run behavior of some repeatable data mechanism is not appropriate second because data sets tend to be small and collinear the effects of explanatory variables are estimated imprecisely in most applications the first problem is generally ignored and the second is solved by imposing restrictions on the regression model to obtain sensible results the bayesian model of statistical inference provides a unified solution to these two distinct problems of quantitative comparative research two features of bayesian inference are important in this context first probability is conceived subjectively as characterizing a researcher s uncertainty about the parameters of a statistical model this subjective probability concept seems particularly useful in comparative settings where the data are typically convenience samples not generated by a known probability mechanism such as random sampling second bayesian inference allows the inclusion of other information in addition to the quantitative sample information again this seems useful in the comparative context where rich historical material is commonly available sparking ideas for researchers but formally discarded in the final analysis in the bayesian approach this historical material can be formally incorporated into the analysis we begin by detailing why the nonstochastic and weak data typical of comparative research are problematic for conventional linear regression analysis we next introduce some ideas about bayesian inference and describe bayesian regression analysis these ideas are applied to a comparative analysis of unionization the subject of a recent exchange in the american political science review between michael wallerstein and john stephens stephens and wallerstein 1991 wallerstein 1989 the bayesian regressions we present are supplemented with a sensitivity analysis that investigates how our conclusions depend upon the sample data and our prior beliefs although we survey some ideas in bayesian statistics a full introduction to the bayesian approach to statistical inference is beyond our scope here good book length treatments are pollard 1986 lee 1989 and at a slightly higher level press 1989 our intention here is to spotlight problematic but ignored issues of statistical inference in a common area of application the bayesian alternative that we present represents just one way forward to address these inferential problems

equilibrium price paths in sequential auctions with stochastic supply abstract in many sequential auctions supply is unknown ex ante consequently price formation depends on information regarding supply uncertain supply reduces the option value and yields declining prices however prices increase if it becomes known that supply falls short of expectations

scale economies and the dynamics of recurring auctions we analyze the dynamics of a game of sequential bidding in the presence of stochastic scale effects either economies or diseconomies of scale we show that economies of scale give rise to declining expected equilibrium prices whereas the converse is not generally true moreover first and second price auctions are not always revenue equivalent economies of scale make second price auctions more profitable for the seller whereas revenue equivalence may be preserved in the case of diseconomies

active learning a correction these changes stem from a bug which we discovered recently in the measurement error section of the passive learning part of our adaptive control code dual thus the results for the macrae model in section 2 of the paper are not affected because it does not include measurement error also the mean values in the first table above are not altered for the active learning and certainty equivalence solutions but rather only for the passive learning solution the modified results reported above show that the passive learning solutions to the single control variable abel model performed relatively worse than in our earlier report

electoral competition and agricultural support in oecd countries agricultural trade protectionism in developed countries remains a politically charged issue yet few studies have attempted to explain the political dynamics behind this important trade issue we consider agricultural subsidies as a type of distributive policy that targets the agricultural sector at the expense of consumers and taxpayers based on cox 1987 1990 and myerson 1993 we argue that electoral systems that encourage politicians to appeal to a narrow constituency tend to have a higher level of agricultural support we test this theoretical hypothesis using oecd agricultural support data disaggregated by commodity and country a cross classified multilevel model is employed to account for complex variation of agricultural support across countries commodities and time our empirical results show that electoral systems that encourage politicians to target narrow broad constituencies are associated with relatively high low levels of agricultural subsidies

bottom fishing and declining prices in sequential auctions abstract we study standard sequential auctions in which the seller chooses the order of sale and right to choose auctions in which the winner chooses her preferred item from the remaining items empirically prices in sequential auctions tend to decline and sellers often hold right to choose auctions in our setting the right to choose format guarantees declining prices and efficiency in the standard auction a buyer may submit a low bid for the first item bottom fishing despite its being her less preferred item an example shows that the standard auction has declining prices is inefficient and gives lower expected revenue than the right to choose journal of economic literature classification numbers d44 d82

majoritarian electoral systems and consumer power price level evidence from the oecd countries a straightforward extension of the standard stigler peltzman model of regulation coupled with a taagepera shugart analysis of electoral system effects suggests a that the greater seat vote elasticities of majoritarian electoral systems will tilt policy in favor of consumers while propor tional systems should strengthen producers and b that the pro con sumer bias of majoritarian systems should be manifested in systemati cally lower prices empirical tests controlling for the structural determi nants of national price levels estab lished in the earlier law of one price literature establish majoritarian elec toral systems as a significant and robust predictor lowering national price levels in the mean oecd coun

centripetal and centrifugal incentives in electoral systems this paper investigates how electoral laws affect the position taking incentives of parties and candidates it seeks to extend the finding presented in the classical median voter theorem to a wide class of electoral systems or to show the limits of such extension the factors examined are the district magnitude the electoral formula the number of votes each voter is allowed to cast whether voters can cumulate their votes and whether voters can partially abstain i suggest a crude division of electoral systems into those producing predominantly centripetal incentives and those producing predominantly centrifugal incentives among the factors found to produce centripetal incentives at least in noncumulative systems are the following increases in the number of votes per voter outlawry of partial abstention and decreases in the district magnitude in systems allowing the cumulation of votes matters are a bit different

signal jamming in a sequential auction abstract in a sequence of first price auctions with stable private values bidders strategically conceal their private information until the last auction we characterize equilibrium bidding and explore how such signal jamming affects the dynamics of equilibrium prices

legislators and interest groups how unorganized interests get represented this paper derives a supply price for public policy using a constrained maximization model in the model three sets of agents each have preferences over outcomes organized interest groups offer campaign contributions to improve their own wealth voters offer votes to obtain outcomes closer to their most preferred outcomes and legislators seek both campaign contributions and votes to obtain reelection a given legislator s supply price for policy is shown to depend on the productivity of his effort as determined by committee assignments priority and ability and by the preferences of his unorganized constituency in the home district two extreme assumptions about the effectiveness of campaign spending in eliciting votes are used to illustrate the comparative statics properties of the model the prediction of the model is that interest groups will in general seek out legislators whose voters are indifferent to the policy the interest group seeks thus voters who do have preferences over policy are in effect represented even though they are not organized

short versus long coalitions electoral accountability and the size of the public sector this article examines the policy consequences of the number of parties in government we argue that parties externalize costs not borne by their support groups larger parties thus internalize more costs than small parties because they represent more groups this argument implies that the public sector should be larger the more parties there are in the government coalition we test this prediction using yearly time series cross sectional data from 1970 to 1998 in 17 european countries we find that increasing the number of parties in government increases the fraction of gdp accounted for by government spending by close to half a percentage point or more than one billion current dollars in the typical year we find little support for the alternative claim that the number of legislative parties affects the size of the public sector except via the number of parties in government
