reciprocal relationships and mechanism design we study an incomplete information game in which players can coordinate their actions by contracting among themselves we model this relationship as a reciprocal contracting procedure where each player has the ability to make commitments contingent on the other players commitments we differ from the rest of the literature on reciprocal contracting by assuming that punishments cannot be enforced in the event that cooperation breaks down we fully characterize the outcomes that can be supported as perfect bayesian equilibrium outcomes in such an environment we use our characterization to show that the set of supportable outcomes with reciprocal contracting is larger than the set of outcomes available in a centralized mechanism design environment in which the mechanism designer is constrained by his inability to enforce punishments against non participants the difference stems from the players ability in our contracting game to convey partial information about their types at the time they offer contracts we discuss the implications of our analysis for modelling collusion between multiple agents interacting with the same principal

political cycles in oecd economies this paper studies whether the dynamic behaviour of gnp growth unemployment and inflation is systematically affected by the timing of elections and of changes of governments the sample include the last three decades in 18 oecd economies we explicitly test the implication of several models of political cycles both of the opportunistic and of the partisan type also we confront the implication of recent rational models with more traditional approaches our results can be summarized as follows a the political business cycle hypothesis as formulated in nordhaus 1975 on output and unemployment is generally rejected by the data b inflation tends to increase immediately after elections perhaps as a result of pre electoral expansionary monetary and fiscal policies c we find evidence of temporary partisan differences in output and unemployment and of long run partisan differences in the inflation rate as implied by the rational partisan theory by alesina 1987 d we find virtually no evidence of permanent partisan differences in output growth and unemployment

implications of ethnic diversity ethnically differentiated societies are often regarded as dysfunctional with poor economic performance and a high risk of violent civil conflict the author distinguishes between dominance in which one group constitutes a majority and fractionalization in which there are many small groups in terms of overall economic performance the research shows that both theoretically and empirically fractionalization is normally unproblematic in democracies although it can be damaging in dictatorships in terms of the risk of civil war the author shows that both theoretically and empirically fractionalization actually makes societies safer while dominance increases the risk of conflict a policy implication is that fractionalized societies are viable and secession should be discouraged

independent central banks low inflation at no costs a widely held view suggests that politically independent central banks bring about relatively low and stable inflation rates a more debated question is whether one has to pay for this good outcome with more real instability in his seminal contribution kenneth rogoff 1985 suggests that an independent and inflation averse central bank reduces average inflation but as a result increases output variability the conservative central banker reduces the inflation bias due to the time inconsistency problem but stabilizes less however alesina and summers 1993 do not find that at least within the oecd countries more independent central banks are associated with more variability of growth or unemployment thus they conclude that independent central banks bring about low inflation at no apparent real costs the point of this paper is to provide theoretical underpinnings to this finding which is in contrast to rogoff 1985 2 the basic idea is that one can isolate two sources of output variability one is the economic variability induced by standard exogenous shocks that monetary policy is supposed to stabilize for instance money demand shocks or supply shocks the second source of variability is political or more generally policy induced this is the variability introduced in the system by the uncertainty about the future course of policy for instance alesina 1987 studies the effect of uncertain electoral outcomes in a model where the two contending parties have different preferences over inflation and unemployment an inflation averse independent central banker does not stabilize as much the economic variability in order to keep inflation low and stable this is rogoff s point however by insulating monetary policy from political pressures an independent central bank can reduce the political variability the overall effect of independence on output variability is thus ambiguous this result is consistent at least prima facie with the evidence in alesina and summers 1993 on the lack of correlation between centralbank independence and output variability in fact it is possible that when the politically induced output variability is predominant a more independent central bank reduces average inflation and the variance of output

some macroeconomics for the 21st century this note describes a numerical simulation of a model of economic growth a simplified version of robert tamura s 1996 model of world income dynamics based on technology diffusion the model makes predictions for trends in average world income growth and about the evolution of the relative income distribution that accord well with observation the model is used to forecast the course of world income growth and income inequality over the century to come

a non expected utility model and its application in practical auctions this article presents a non expected utility decision model which is nonlinear in the winning probabilities the model not only explicitly expresses bidders attitudes to risk but also addresses t

externalities and asymmetric information a reconsideration of the pigovian theory of regulating externalities via taxation is undertaken for environments with private information the presence of private information may have no effect on the social optimum but when it has an impact it is to cause a group of different agents to share the same production or consumption levels the model developed provides an appealing characterization of when such situations transpire they occur when the individuals who desire most to engage in some activity are the ones who society least wants to participate since such instances could potentially be regulated by the imposition of quantity controls this may explain authorities apparent predilection for quantity limits rather than tax cum subsidy schemes to manage many externalities

macroeconomic policy in a two party system as a repeated game this paper considers the interaction of two parties with different objectives concerning inflation and unemployment and rational and forward looking wage setters if discretionary policies are followed an economic cycle related to the political cycle results in equilibrium this cycle is significantly different from the traditional political business cycle reputational mechanisms due to the repeated interaction of the two parties and the public or commitments to a common policy rule can improve upon the discretionary outcome by reducing or eliminating the magnitude of the economic fluctuations

how not to sell nuclear weapons we consider situations where a sale affects the ensuing interaction between potential buyers these situations are modeled by assuming that an agent who does not acquire the object for sale incurs an identity dependent externality we construct a revenue maximizing auction for the seller we observe that 1 outside options and participation constraints are endogenous 2 the seller extracts surplus also from agents who do not obtain the auctioned object 3 the seller is better off by not selling at all while obtaining some payments if externalities are much larger than valuations

greenhouse gas emissions from power generation and consumption in a nordic perspective during the last decade there has been an intensive debate on going in sweden about how power generation and use affect global warming more precisely the discussion has considered how electricity shall be assessed from an environmental and climate perspective in different situations this article gives a critical analysis on the main viewpoints a number of environmental impact assessment principles are outlined and critically examined concepts like average electricity and marginal electricity are discussed and electricity disclosure as a basis for evaluation is addressed the impact from emission trading and tradable green certificates is also considered recommendations to concerned stakeholders are given the clash points in the swedish debate are highlighted and thus made available to a broader audience outside scandinavia

competitive effect of cross shareholdings in all pay auctions with complete information abstract this paper investigates the competitive effect of cross shareholdings in winner take all all pay auctions with two asymmetric bidders we show that cross shareholdings may paradoxically create a pro competitive effect and elicit more effort than a standard contest without cross ownership this observation runs in contrast to the anti competitive effect that cross shareholdings usually create in standard oligopolistic settings such as cournot or bertrand competitions both bidding costs and the sizes of cross shares affect the resultant total effort non monotonically neither a cross share nor a higher bidding cost necessarily decreases effort supply a complete account of equilibrium bidding behaviors is provided and the necessary and sufficient conditions under which cross shareholdings lead to higher or lower levels of overall effort are identified however the pro competitive effect comes at a loss of efficiency

bid costs and endogenous bid caps we study contests where several privately informed agents bid for a price all bidders bear a cost of bidding that is an increasing function of their bids and moreover bids may be capped we show that regardless of the number of bidders if agents have linear or concave cost functions then setting a bid cap is not profitable for a designer who wishes to maximize the average bid on the other hand if agents have convex cost functions i e an increasing marginal cost then affectively capping the bids is profitable for a designer facing a sufficiently large number of bidders

income distribution political instability and investment abstract this paper successfully tests on a sample of 71 countries for the period 1960 85 the following hypotheses income inequality by fuelling social discontent increases sociopolitical instability the latter by creating uncertainty in the politico economic environment reduces investment as a consequence income inequality and investment are inversely related since investment is a primary engine of growth this paper identifies a channel for an inverse relationship between income inequality and growth we measure socio political instability with indices which capture the occurrence of more or less violent phenomena of political unrest and we test our hypotheses by estimating a two equation model in which the endogenous variables are investment and an index of socio political instability our results are robust to sensitivity analysis on the specification of the model and the measure of political instability and are unchanged when the model is estimated using robust regression techniques

the political economy of inflation and stabilization in developing countries the traditional literature on inflation in developing countries has focused on three main determinants of inflationary pressures a money creation b fiscal imbalances and c cost push elements while the first two factors have been emphasized by authors of a monetarist persuasion cost factors have played a crucial role in the structuralist theories developed during the 1950s and 1960s however more recent analyses on inflation and stabilization have shifted their attention away from traditional direct economic causes of inflation such as money creation toward political and institutional determinants of inflationary forces this new literature which has come to be known as the political economy approach to macroeconomic policy has built on some important insights of game theory and the theory of public choice trying to explain why some governments decide to run large fiscal deficits and to rely heavily on the inflation tax typically in answering these questions this recent strand of the literature has emphasized the role of political instability credibility reputation and political cycles 2 in spite of providing some important new insights into the determinants of inflation this new literature is subject to two limitations first until recently most of the contributions have been theoretical without providing empirical tests on their most important implications and second the emphasis has been almost exclusively on the industrialized countries ignoring the developing nations the purpose of this article is to discuss selectively some of the most important insights of this new literature on policy making from the developing countries perspective i will emphasize the policy implications of this approach to inflationary analysis and discuss some of the limited empirical results

takeover contests toeholds and deterrence we consider a setting in which two potential buyers one with a prior toehold and one without compete in a takeover modeled as an ascending auction with participating costs the toeholder is more aggressive during the takeover process because she is also a seller of her own shares the non toeholder anticipates this extra aggressiveness of the toeholder thus he is deterred from participating unless he has a high valuation for the target company this leads to large inefficiency losses for many configurations expected target returns are first increasing then decreasing in the size of the toehold

auction guarantees for works of art abstract this paper addresses the question of whether auction guarantees change the bidding environment and whether they cause a change in price once the value of an item is taken into account we analyze both the cases of third party guarantees and in house guarantees we use two datasets one of christie s and sotheby s contemporary and impressionist evening sales from january 2010 to february 2012 and another larger dataset consisting of all items auctioned at christie s from 2001 to may 2011 while more expensive items are more likely to have guarantees we find little empirical evidence to suggest an effect on price from the guarantee itself once the value of the item is taken into account

collusive bidder behavior at single object second price and english auctions models of collusive bidder behavior at single object second price and english auctions are provided the ind ependent private values model is generalized to permit the formulatio n of coalitions and a strategic response by the auctioneer cooperati ve strategies are found to be dominant in these models coalitions of any size are viable and the payoff to each member increases with th e size of the coalition in addition the collusive strategies of the coalition represent a noncooperative equilibrium the optimal respon se of the auctioneer is to establish a reserve price that is a functi on of the coalition s size these and other features of the model are found to be consistent with the essential features of actual behavio r copyright 1987 by university of chicago press

partnerships and double auctions with interdependent valuations in a symmetric independent private values setting a sealed bid double auction dissolves a partnership efficiently this well known result remains valid in a model with interdependent valuations however if common values components are large agents might prefer not to participate in a double auction therefore a simple extention of the rules of double auctions is suggested that ensures participation even though these modified double auctions are not incentive efficient they still realize gains from trade and can be implemented without knowledge about the specifications of the model

on the continuous equilibria of affiliated value all pay auctions with private budget constraints abstract we consider all pay auctions in the presence of interdependent affiliated valuations and private budget constraints for the sealed bid all pay auction we characterize a symmetric equilibrium in continuous strategies for the case of n bidders budget constraints encourage more aggressive bidding among participants with large endowments and intermediate valuations we extend our results to the war of attrition where we show that budget constraints lead to a uniform amplification of equilibrium bids among bidders with sufficient endowments an example shows that with both interdependent valuations and private budget constraints a revenue ranking between the two auction formats is generally not possible equilibria with discontinuous bidding strategies are discussed

markets for ownership the prevailing economic theory of the firm based on a property rights perspective has demonstrated that ownership by dispensable outside parties is an inefficient outcome relative to ownership by productive agents in order to better understand observed patterns of ownership this paper considers the outcome of ma rkets for ownership that operate prior to production taking place the main result is that outside parties will often become the equilibrium asset owners this is precisely because but for ownership such parties would not earn rents in contrast productive agents earn rents even when they do not own assets given that their contribution is complementary with other productive agents their willingness to pay for ownership is less than that of an outside party this result is robust to the introduction of moderate levels of inefficiency arising from outside ownership and to a consideration of opportunities for re sale before production begins the main conclusion drawn is that the nature of the operation of markets for ownership stands alongside incentive effects as important predictors of firm boundaries journal of economic literature classification numbers d23 l22

optimal bidding in auctions from a game theory perspective abstract the game theoretic perspective in auction bidding has provided a powerful normative framework for the analysis of auctions and it has generated an impressive volume of research contributions tracing this research we review key recent advances which have greatly expanded our understanding of the operation of auctions and produced a more accurate analysis of mechanism design and optimal bidding we follow various experimental studies which have shown that the predictive power of auction theory remains in many cases limited for this reason we concentrate on research themes which enhance the applicability of auction theory leading to more realistic descriptions of bidding behaviors we identify important innovations which expand the environment of auction bidding and carry us beyond rational decision making we conclude providing directions of future research and discussing their implications

asymmetric price benefits auctions abstract this paper studies the performance of two auction procedures for allocating the assets of a dissolving partnership when partners valuations for the assets are independent and asymmetrically distributed with one partner reputed to be more interested in the assets to be divided we provide results on existence and uniqueness of the equilibrium induced by these auctions comparative statics are developed especially the differences between relative efficiency and revenue from the two auctions journal of economic literature classification numbers c72 d39 d44 d52 d74 d82

on the efficient provision of public goods by means of biased lotteries the two player case in this paper we analyze how biased lotteries can be used to overcome the free riding problem in voluntary public good provision we characterize the optimal combinations of bias and lottery prize and the conditions that guarantee efficient public good provision in equilibrium

initial shareholdings and overbidding in takeover contests within the context of takeovers this paper shows that in private value auctions the optimal individually rational strategy for a bidder with partial ownership of the item is to overbid i e to bid more than his valuation this strategy however can lead to i an inefficient outcome and ii the winning bidder making a net loss further the overbidding result implies that the presence of a large shareholder increases the bid premium in single bidder takeovers at the expense of reducing the probability of the takeover actually occurring

on the politics of property rights by haber razo and maurer stephen haber et al explore economic growth in key sectors of the mexican economy 1876 1929 an era of political instability and 1914 17 civil war the authors demonstrate that economic growth continued amidst political instability and offer an explanation for their counterintuitive finding reviewing the evidence advanced by the authors robert bates summarizes and comments on their argument and applies it to out of sample data from africa

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

choosing the competition and patent licensing this article examines licensing as a means of choosing the competitors which a patentee monopolist will face in the period after the patent expires the queue of entrants consists of two firms which differ in their relative strengths as competitors for example by size or level of marginal cost by structuring the industry to be composed of weak competitors the incumbent is able to prolong its dominant position in the industry after the patent expires examples are presented in which the evidence suggests that choosing the competition was an important motivation of the licensor s behavior

the welfare state and competitiveness in all industrial countries fiscal policy is increasingly about redistribution in this paper the authors study redistribution across different types of agents in a world characterized by the presence of labor unions and distortionary taxation they show that an increase in transfers financed by distortionary taxation has nonlinear effects on unit labor costs relative to the other countries depending on the degree of centralization of the wage setting process in the labor market the authors find considerable empirical support for the model in a sample of fourteen oecd countries copyright 1997 by american economic association

powerful pacifists democratic states and war democracies are less likely to fight wars with each other they are also more likely to prevail in wars with autocratic states i offer an explanation of this syndrome of powerful pacifism drawn from the microeconomic theory of the state state rent seeking creates an imperialist bias in a country s foreign policy this bias is smallest in democracies where the costs to society of controlling the state are relatively low and greatest in autocracies where the costs are higher as a result of this bias autocracies will be more expansionist and in turn war prone in their relations with each other where the absence of this imperialist bias is manifest the relative pacifism of democracies appears in addition democracies constrained by their societies from earning rents will devote greater absolute resources to security enjoy greater societal support for their policies and tend to form overwhelming countercoalitions against expansionist autocracies it follows that democracies will be more likely to win wars

should lotteries offer discounts on multiple tickets in a complete information setting we show that the standard lottery in which each lottery ticket is offered for the same price is an optimal fundraising mechanism in the presence of strong asymmetries in the way bettors value the prize and the public good provided with the lottery proceeds when participants are more homogeneous it is optimal to offer discounts for the purchase of multiple tickets

endogenous participation in charity auctions abstract data from a recent field experiment suggests that differences in participation rates are responsible for much of the variations in charity auction revenues across formats we provide a theoretical framework for the analysis of this and other related results the model illustrates the limits of previous results that assume full participation and introduces some new considerations to the choice of auction mechanism it also implies however that the data cannot be explained in terms of participation costs alone there must exist mechanism specific obstacles to participation

electricity from a competitive market in life cycle analysis abstract we propose that data from specific contracted electricity production plants should be used for electricity consumption in life cycle analysis when electricity is purchased from a competitive market electricity may thereby contribute less to the sum of environmental load than when data of marginal or average plants are used by this method the potential of electricity supplied through the grid to be a part of ambitious industrial environmental policy is made visible as shown on the swedish market a demand for deliveries from environmentally preferable plants can introduce price differences between different types of production thereby promoting investments in improved environmental performance of electricity production

how not to raise money we show that standard winner pay auctions are inept fund raising mechanisms because of the positive externality bidders forgo if they top another s high bid revenues are suppressed as a result and remain finite even when bidders value a dollar donated the same as a dollar kept this problem does not occur in lotteries and all pay auctions where bidders pay irrespective of whether they win we introduce a general class of all pay auctions rank their revenues and illustrate how they dominate lotteries and winner pay formats the optimal fund raising mechanism is an all pay auction augmented with an entry fee and reserve price

the influence of political distortions on economic performance alberto alesina is the nathaniel ropes professor of political economy and chairman of the department of economics at harvard university in this interview he discusses with brian snowdon his views on several important contemporary issues including politics and the business cycle budget deficits currency unions the european union the size of nations economic growth inequality democracy foreign aid ethnic fractionalisation and the welfare state in the us and europe

economic integration and political disintegration in a world of trade restrictions large countries enjoy economic benefits because political boundaries determine the size of the market under free trade and global markets even relatively small cultural linguistic or ethnic groups can benefit from forming small homogeneous political jurisdictions this paper provides a formal model of the relationship between openness and the equilibrium number and size of countries and successfully tests two implications of the model firstly the economic benefits of country size are mediated by the degree of openness to trade secondly the history of nation state creations and secessions is influenced by the trade regime

the european union a politically incorrect view to the united states the united states of europe the answer is no as article 1 of the recent european constitution states europe is and will remain a union of independent countries nevertheless an unresolved tension between those who would like the european union to evolve into a supernational entity the federalists or supernationalists and those who would like it to stay a union of independent governments the intergovernmentalists has shaped much of the history of european institutions the natural starting point for a u s scholar studying the process of european integration would be the notion of division of powers europe has developed instead a system of institutional balance based on overlapping jurisdictions the legislative executive and regulatory powers are shared by many institutions so much so that the distinction itself between legislative and executive acts is blurred something that would make james madison turn in his grave it could hardly be otherwise the european union has been created gradually by a group of established countries with different secular histories including dozens of internecine wars and different institutions the european countries were understandably wary that a single european institution would absorb too much of their own sovereignty hence the emphasis on balance but institutional balance and overlapping jurisdictions also lead to turf wars between institutions to

spatial and temporal variations of marginal electricity generation the case of the finnish nordic and european energy systems up to 2030 abstract assumptions related to energy generation often play a decisive role in abatement studies for estimating the effects of demand side interventions however there can be significant geographical and temporal variation in the emission intensities of electricity generation in different regions the aim of this article is to describe how spatial and temporal variations related to a particular energy system may affect an electricity generation unit operating on the margins the approach takes the generation mix within interconnected electricity markets and the exchange of electricity between these markets into account the short term 2009 2010 and long term until 2030 hour by hour marginal electricity generation unit and marginal emission intensities are identified for electricity use using the finnish nordic and european energy systems as actual cases the estimated marginal electricity generation technology and marginal emission intensities for electricity use differed significantly within the studied time horizon and between the studied countries and energy systems furthermore due to the projected structural changes in the energy systems i e changes in the fuel mix and electricity generation technologies the carbon dioxide co 2 intensity of marginal electricity generation will decrease in the nordic countries and in the eu in the long term however the approach used for calculating the effect of change in electricity exchange on the margin increased the variability of the results considerably for some nordic countries such as sweden and norway whose export of electricity was high and whose marginal generation mix differed significantly from the european system furthermore the spatial and temporal variations of marginal electricity generation will increase in the future this variation combined with the interconnections between market areas for exchanging electricity in the eu will require improved understanding of the impacts of exchanged marginal electricity generation on the possible emission leakage between eu countries to better inform policy decisions

on the evolution of prize perceptions in contests abstract we apply an indirect evolutionary approach to players perceived prize valuations in contests evolution in finite populations leads to preferences that overstate the prize s material value and induce overexpenditure we establish an equivalence between evolutionarily stable strategies and the behavior induced by evolutionarily stable preferences

understanding economic policy reform one of the eventual consequences of the global debt crisis was a wave of market oriented economic reforms this paper discusses the state of our knowledge on the political economy of this process why were inefficient and often unsustainable policies maintained for so long why are so many governments reforming now after decades of adherence to policies of an opposite kind have the reformers internalized the correct lessons from the east asian experience finally are there any helpful rules for reformers to follow in guiding their policies through complicated political terrain

central bank independence and macroeconomic performance some comparative evidence this note uses information on a sample of sixteen oecd countries to assess the relationship between central bank independence and macroeconomic performance as previous work suggests politically controlled central banks are more likely to pursue policies that lead to high and variable inflation however the authors find little evidence that political control of central bank policy has any impact on measures of the level or variability of growth unemployment or the ex ante real interest rate copyright 1993 by ohio state university press

central bank independence an update of theory and evidence this paper reviews recent research on central bank independence cbi after we have distinguished between independence and conservativeness research in which the inflationary bias is endogenised is reviewed finally the various challenges that have been raised against previous empirical findings on cbi are discussed we conclude that the negative relationship between cbi and inflation is quite robust

political macroeconomics a survey of recent developments the paper surveys political macroeconomics covering its development from rogoff s conservative central banker to the most recent discussions of monetary policy and institutional design topics include the inflation stabilization trade off central bank independence with escape clauses and overruling with costs inflation targets performance contracts for monetary authorities and the consequences of output persistence for these issues further topics are the political business cycle when output is persistent the political macroeconomics of fiscal policy the government spending bias and the game theoretic interaction between fiscal and monetary policy all work is discussed within a coherent analytical framework

auctions with price proportional benefits to bidders after some auctions including amish estate sales and buyer rings knockout auctions each bidder receives a share of the revenue generated by the auction we show that in the symmetric case equilibrium bids in both first price sealed bid auctions and oral auctions increase as each bidder s share increases in the case of independent signals oral auctions result in higher expected equilibrium prices than do first price sealed bid auctions journal of economic literature classification number d44

when less is more rationing and rent dissipation in stochastic contests this paper shows how to maximize revenue when a contest is noisy we consider a case where two or more contestants bid for a prize in a stochastic contest where all bidders value the prize equally we show that whenever a tullock contest yields under dissipation the auctioneer s revenue can be increased by optimally fixing the number of tickets in particular in a stochastic contest with proportional probabilities it is possible to obtain almost full rent dissipation we test this hypothesis with a laboratory experiment the results indicate that as predicted revenue is significantly higher in a lottery with rationing than in a standard lottery on the other hand an alternative rationing mechanism that does not limit total expenditures fails to increase revenue relative to a standard lottery

economic risk and political risk in fiscal unions a fiscal programme that redistributes income from rich to poor individuals indirectly redistributes tax revenues from regions hit by a favou rable shock to regions hit by an unfavourable one centralised fiscal redistribution has therefore been advocated as a way to insure individuals against region specific shocks in this paper we argue that a centralised fiscal policy while reducing the uncertainty on the tax base may create additional uncertainty on the tax rate using a simple model we show that the higher uncertainty on the policy instrument might more than offset the lower uncertainty on the tax base several countries around the world are breaking up e g the former soviet union and in others regional movements are becoming more vocal in demanding more autonomy e g italy spain at the same time several western european countries are integrating in a supernational community fiscal policy issues and in particular the level of centralisation of fiscal decisions are important considerations in the formation or collapse of political jurisdictions or of federations of regions and countries 1 a long tradition in public finance argues that a centralised fiscal system can reach more efficient outcomes by better internalising the numerous externalities associated with both the expenditure and the revenue sides of fiscal policy particularly when factors are mobile this line of argument applies to both the provision of public goods gordon 1983 and to redistributive fiscal policy pauli 1973 ladd and doolittle 1982 brown and oates 1987 a counter argument to this conclusion is developed in perotti 1997 who shows that in the presence of differences in say labour markets or the administration of fiscal policy centralised redistribution can lead to a more inefficient allocation of resources a second argument in favour of centralised fiscal policy is based on the insurance properties of redistribution when different countries are hit by

private information and altruism in bidding roscas this article studies how altruism improves allocations in a private information environment where strategic behaviour reduces economic welfare a theoretical analysis establishes that in an environment characterised by uncertainty and private information outcomes of auctions in rotating savings and credit associations roscas are more efficient when bidders preferences are altruistic rather than selfish a semi parametric structural estimation technique for rosca auctions is presented a parametric structural estimation identifies interactions between group characteristics and bidder altruism it is found that effective leadership and intra group diversity are associated with a greater extent of bidder altruism and thus more efficient intra rosca allocations

on the profitability of reducing competition in all pay auctions with risk averse bidders abstract in an all pay auction with risk averse bidders the seller s revenue is decreasing in the number of competitors if either the bidders are very risk averse or the distribution for the valuations attaches probability almost one to a single value

rank order competition in the voluntary provision of impure public goods publicly provided goods often create differential payoffs due to timely or spatial distances of group members we design and test a provision mechanism which utilizes rank competition to mitigate free riding in impure public goods in our rank order voluntary contribution mechanism rank order vcm group members compete via observable contributions for a larger share of the public good high contributors receive preferential access a larger share while low contributors receive restricted access a lower share in a laboratory experiment rank order vcm elicits median contributions equal to the full endowment throughout the finitely played games with constant groups in the control treatment with randomly assigned ranks the contributions are significantly lower and decline over time we thus provide evidence of rank competition in situations where discriminatory access to public goods is possible being efficiency enhancing

determinants of democracy a panel study of over 100 countries from 1960 to 1995 finds that improvements in the standard of living predict increase in democracy as measured by a subjective indicator of electoral rights the propensity for democracy rises with per capita gdp primary schooling and a smaller gap between male and female primary attainment for a given standard of living democaracy tends to fall with urbnization and with a greater reliance on natrual resources democracy has little relation to country size but rises with the middle class share of income the apparently strong relation of democracy to colonial heritage mostly disappears when the economic variables are held constant similarly the allowance for these economic variables weakens the interplay between democracy and religious affiliation however negative effects from muslim and non religious affiliations remain intact

optimal auctions with asymmetric financial externalities abstract this paper studies optimal auction design with asymmetric linear financial externalities among bidders when the matrix that relates bidders payoffs to their payments is nonsingular the payment related component in the design objective must equal a unique linear combination of its counterparts in bidder s payoffs if all multipliers of the linear combination are nonnegative a modified myerson procedure is discovered for deriving the optimal design if any multiplier is negative an arbitrarily high value can be achieved for design objective by setting proper fixed transfers to bidders when the matrix is singular the unbounded optimum result typically prevails we applied our method to auctions with cross shareholdings and charity auctions for revenue maximizing and efficient designs

optimal allocation without transfer payments abstract often an organization or government must allocate goods without collecting payment in return this may pose a difficult problem either when agents receiving those goods have private information in regards to their values or needs in this paper we find an optimal mechanism to allocate goods when the designer is benevolent while the designer cannot charge agents he can receive a costly but wasteful signal from them we find conditions for cases in which ignoring these costly signals by giving agents equal share or using lotteries if the goods are indivisible is optimal in other cases those that send the highest signal should receive the goods however we then show that there exist cases where more complicated mechanisms are superior also we show that the optimal mechanism is independent of the scarcity of the goods being allocated

opportunism in multilateral vertical contracting nondiscrimination exclusivity and uniformity comment an input supplier selling to competing downstream firms would benefit from publicly committing at the outset to all contracts efficient commitment however would require complete contracts the authors study instead bilateral contracting without commitment regarding others terms each firm then fears that the supplier might opportunistically renegotiate another s contract to increase bilateral profit at the firm s expense the authors show that nondiscrimination clauses generally cannot curb such third party opportunism even with symmetric firms to reassure firms crude forms of commitment may be adopted this could explain the pervasiveness of exclusivity arrangements and the striking uniformity and intertemporal rigidity of franchise contracts copyright 1994 by american economic association

the political economy of growth a critical survey of the recent literature this article reviews the recent literature on the political economy of growth focusing on the research that has developed at the intersection of the endogenous growth literature and the new political economy it explores the relationship among four key variables economic growth and capital accumulation political instability political freedom and democratic institutions and income inequality

agreeing on efficient emissions reduction we propose a simple contest based mechanism providing incentives to reduce harmful emissions to their efficient level without infringing upon productive efficiency participation in the most stylized form of the scheme is voluntary and individually rational all rules are mutually agreeable and are unanimously adopted if proposed the scheme balances its budget and requires no principal in a perhaps more realistic stochastic output version which could potentially inform policy decisions we show that the transfers required by the efficient mechanism create a mutual insurance motive that can serve as an effective rationale for the gradual formation of international environmental agreements

silent auctions in the field and in the laboratory we analyze data from hundreds of auctions from three field silent auction sessions we focus on the descriptive statistics and on a parametric model of jump bidding we then report data from six laboratory sessions of silent auctions as a controlled environment this allows us to evaluate the auctions in ways not available within the field the laboratory experiments capture essential features of the field sessions and thus comprise a credible laboratory testbed for further examination of institutional perturbations in the silent auction jel d44 h41

fiscal discipline and the budget process the critical economic policy issue for many oecd countries developing countries and transition economies currently is fiscal consolidation and the maintenance of long run fiscal balance two related components underlie this general goal first several countries face the issue of deficit reduction particularly those countries with high debt gdp ratios second it is becoming increasingly apparent that major reforms of the welfare system and specifically of social security systems are critical ingredients of a long lasting fiscal consolidation see alesina and perotti 1995a in the case of monetary policy a constructive discussion has generated a widespread consensus about the benefits of different monetary institutions relatively few economists dispute the benefits of a certain amount of central bank independence even though different commentators and policymakers may disagree on the optimal degree of independence also a contracting approach has highlighted the benefit of inflation targeting and of certain institutional relationships contracts between the executive and the central bank a similar theoretical and empirical discussion on the role of budget procedures and budget institutions is just beginning in this paper we ask the following two questions i do budget procedures matter for the determination of the budget balance and its composition ii are there certain institutional reforms that one should feel comfortable in recommending based on the relatively scarce empirical evidence available we tentatively answer yes to the first question budget procedures matter on the second question we suggest that the two critical areas of reform are first more transparency second a strengthening of the roles of the executive branch vis a vis the legislature and of the treasury minister vis a vis the rest of the executive branch in order to achieve a centralized and top bottom approach to the budget process

fees versus royalties and the private value of a patent we compare how much profit an owner of a patented cost reducing invention can realize by licensing it to an oligopolistic industry producing a homogeneous product by means of a fixed fee or a per unit royalty our analysis is conducted in terms of a noncooperative game involving n 1 players the inventor and the n firms in this game the inventor acts as a stackelberg leader and it has a unique subgame perfect equilibrium in pure strategies it is shown that licensing by means of a fixed fee is superior to licensing by means of a royalty for both the inventor and consumers only a drastic innovation is licensed to a single producer

auction fever rising revenue in second price auction formats the prevalent term auction fever visualizes that ascending auctions inconsistent with theory are likely to provoke higher bids than one shot auctions to explore and isolate causes of auction fever experimentally we design four different strategy proof auction formats and order these according to expected rising bids based on pseudo endowment effect arguments psychological ownership and disparity between willingness to pay and willingness to accept observed revenues in the experiment in the four formats rank as expected if bidders have private uncertain values the private information of a bidder is the distribution of her value a control treatment supports our view that the traditional private certain values approach prevents auction fever in the laboratory another control treatment with a procurement auction relates the auction fever bids to bids in a one shot auction with real endowments we conclude that when bidders are uncertain about their valuations auctions that foster pseudo endowment may raise bids and revenues

environmental labelling of electricity delivery contracts in sweden abstract competition in the electricity market allows customers to choose between suppliers as a consequence customers may demand electricity from specified sources of energy in sweden the swedish society for nature conservation ssnc operates a system of environmental labelling of electricity delivery contracts since 1996 labelling is available for suppliers offering electricity from renewable sources of energy with some additional criteria companies may acquire a licence to use the label by showing ability to deliver such electricity and by agreeing to be audited the system is private independent it is operating on the bases of credibility earned by the ssnc during 90 years as an environmental organisation and 10 years as operator of environmental labelling of consumer products the system is market oriented compatible with wto and eu market principles and independent of governmental environmental restrictions subsidy or quota systems it is relying on voluntary agreements the results are desirable if only a few by electricity under labelled contracts as well as if every customer do so the market is growing a majority of the suppliers have a license and may offer labelled contracts in the year 2000 7 of all electricity sold to final consumers was sold under labelled contracts

jumping and sniping at the silents does it matter for charities abstract despite its popularity as a fundraiser for charities very little research has been done on the bidding and revenue properties of the silent auction this paper examines the consequences of two behaviors common in silent auctions jump bidding and sniping in laboratory experiments with endogenous participation our results suggest that deliberative jumping the result of impatient bidders attempting to telescope time tends to increase revenue while deliberative sniping by experienced bidders tends to decrease it we also show that when charities can encourage jumping and discourage sniping silent auctions can perform as well as their sometimes more entertaining but more expensive alternative the english auction

the generalized war of attrition abstract we model a war of attrition with n k firms competing for n prizes in a natural oligopoly context the k 1 lowest value firms drop out instantaneously even though each firm s value is private information to itself in a standard setting context in which every competitor suffers losses until a standard is chosen even after giving up on its own preferred alternative each firm s exit time is independent both of k and of other players actions our results explain how long it takes to form a winning coalition in politics solving the model is facilitated by the revenue equivalence theorem jel d43 d44 l13 o30

charitable motives and bidding in charity auctions research on bidding in auctions has generally relied on the assumption of self interested bidders this work relaxes that assumption in the context of charity auctions because understanding charitable motives has important implications for auction design and charities fundraising strategies this study investigates bidders specific types of charitable motives and the strength of these motives we carry out three controlled field experiments consisting of real life auctions conducted on a local internet auction site we use a novel design in which we simultaneously run charity and noncharity auctions for identical products and vary the percentage donated to charity results show that auctions with proceeds donated to charity lead to significantly higher selling prices a result due to a higher bidding by bidders with charitable motives rather than to increased bidder entry we also find that increased prices only occur when the charitable donation is a percentage of the auction revenue and that a fixed charitable donation associated with each auction has no effect on prices furthermore we find that prices are increasing in the percentage donated to charity we find considerable support for a model of voluntary shill like bidding where charitable bidders try to increase proceeds in charity auctions we also find that auctions with 25 of revenue donated to charity had higher net revenue than noncharity auctions hence companies may be able to use charity auctions as part of a corporate social responsibility strategy and at the same time increase profitability even though they donate part of the proceeds to charity

how lotteries outperform auctions in their recent paper goeree et al 2005 determine that all pay auctions are better for fundraising activities than lotteries we show that the introduction of asymmetry among participants with complete information could reverse this result complete information seems well suited to some charity environments

on the number and size of nations this paper studies the equilibrium determination of the number of countries in different political regimes and in different economic environments with more or less economic integration we focus on the trade off between the benefits of large jurisdictions and the costs of heterogeneity of large and diverse populations our model implies that i democratization leads to secessions ii in equilibrium one generally observes an inefficiently large number of countries iii the equilibrium number of countries is increasing in the amount of economic integration

rotating savings and credit associations when participants are risk averse we model rotating savings and credit associations roscas among risk averse participants who experience privately observed income shocks a random rosca is not advantageous whereas a bidding rosca is if temporal risk aversion is less pronounced than static risk aversion the payoff scheme of a bidding rosca facilitates risk sharing in the presence of information asymmetries the risk sharing performance of a simple arrangement where a group of homogenous individuals runs several bidding roscas simultaneously is as good as that of a linear risk sharing contract and is more enforceable because it carries a fixed rather than a variable contribution

comparative analysis of litigation systems an auction theoretic approach a simple auction theoretic framework is used to examine symmetric litigation environments where the legal ownership of a disputed asset is unknown to the court the court observes only the quality of the case presented by each party and awards the asset to the party presenting the best case rational litigants influence the quality of their cases by hiring skilful attorneys this framework permits us to compare the equilibrium legal expenditures that arise under a continuum of legal systems the british rule continental rule american rule and some recently proposed legal reforms are special cases of our model

politics and business cycles in industrial democracies politics alberto alesina influences from political competition on macroeconomic policy are often thought to be a source of economic fluctuations politicians are described as being driven by two not mutually exclusive main motivations they want to be reelected and they harbour political or ideological biases when such theories are confronted with actual cycles in a number of industrial countries the pattern of inflation unemployment output and budget deficits indicates that partisan policy making is a fairly widespread phenomenon with more limited evidence that electoral preoccupations result in major fluctuations the combination of partisanship and electoral cycles may easily result in socially undesirable outcomes in particular the degree of politico institutional stability and the independence of the central bank have a bearing on macroeconomic outcomes these observations raise a number of important questions about the design of political institutions

distributive politics and economic growth a crude distinction between economics and politics would be that economics is concerned with expanding the pie while politics is about distributing it in this paper we analyze the relationship between the two we focus on how an economy s initial configuration of resources shapes the political struggle for income and wealth distribution and how that in turn affects long run growth our main conclusion is that inequality is conducive to the adoption of growth retarding policies we derive this result from a simple political economy model of growth and present cross country evidence consistent with it the key feature of our model is that individuals differ in their relative factor endowments we distinguish between two types of factors an accumulated factor called capital and a nonaccumulated factor called labor growth is driven by the expansion of the capital stock which is in turn determined by individual saving decisions long run growth is endogenous as the aggregate production function is taken to be linearly homogeneous in capital and productive government services taken together the provision of government services is financed by a tax on capital because government services are productive a small tax on

charity auctions with multiple goods bidding behavior and revenue abstract in a charity auction with multiple goods we show that the highest losing bid uniform price auction revenue dominates its lowest winning bid counterpart only in the highest losing bid uniform price auction is bidding independent of the number of goods and players and revenue increasing in the number of goods

single versus multiple prize all pay auctions to finance public goods an experimental analysis this paper presents an experimental comparison of single and multiple prize all pay auctions as fundraising mechanisms to finance public goods we consider a setting characterized by heterogenous incomes and incomplete information where single and multiple prize incentive mechanisms are predicted to raise the same overall contribution but different contributions by income level we find that overall for a given total prize sum a single large prize generates higher contributions to the public good than three smaller prizes as predicted by the theory a single prize provides a more effective incentive for high income individuals however contrary to the theoretical predictions multiple prizes do not provide a more effective incentive for low income individuals

do corrupt governments receive less foreign aid critics of foreign aid programs argue that these funds often support corrupt governments and inefficient bureaucracies supporters argue that foreign aid can be used to reward good governments this paper documents that there is no evidence that less corrupt governments receive more foreign aid on the contrary according to some measures of corruption more corrupt governments receive more aid also we could not find any evidence that an increase in foreign aid reduces corruption in summary the answer to the question posed in the title is no

an analysis of the war of attrition and the all pay auction we study the war of attrition and the all pay auction when players signals are affiliated and symmetrically distributed we a find sufficient conditions for the existence of symmetric monotonic equilibrium bidding strategies and b examine the performance of these auction forms in terms of the expected revenue accruing to the seller under our conditions the war of attrition raises greater expected revenue than all other known sealed bid auction forms journal of economic literature classification numbers d44 d82 1997 academic press

hourly based greenhouse gas emissions of electricity cases demonstrating possibilities for households and companies to decrease their emissions abstract greenhouse gas emissions from electricity production are a crucial part of the environmental impact assessments of any kind of product service or consumption usually average annual emissions are used but lately there has been increased interest in the daily based and hourly based emission coefficients for electricity in such markets where the technology mix in the production process includes technologies with different emission factors there is potential for large variation in hourly based emission factors and consequently this offers potential for decreasing the emissions by real time based demand management however in real life the timing of electricity use in households and companies has restrictions in this paper we show illustrative household and company cases with realistic shifts in the timing of electricity use we determine hourly based emission factors and give examples of how emissions may be decreased in households and companies by changing usage patterns and consequently the timing of electricity use with the total amount of electricity consumed remaining unchanged the examples show decreases of emissions in the range 3 8 due to optimised timing indicating that there is important potential for managing hourly based demand loads and the resulting emissions even with realistic assumptions of the timing of consumption

globalisation and economic growth a historical perspective this paper reviews the historical evidence on the relationship between globalisation and economic growth divergence in the growth of income and industrialisation in the twentieth century is documented but it is also noted that international income inequality appears to have decreased since about 1870 and that long run trends in the human development index are much less pessimistic about the experience of developing countries it is argued that trade liberalisation has been good for growth on average but that successful capital liberalisation requires high institutional quality and that the developmental state may have an important role to play in the early stages of development the recent claim by robert lucas that the 21st century will see a massive reduction in income inequality across countries in a globalised world economy is sceptically discussed in the context of empirical evidence that bad institutions are often persistent and that geography is still a major factor in explaining international income differences

erratumauction guarantees for works of art this paper addresses the question of whether auction guarantees change the bidding environment and whether they cause a change in price once the value of an item is taken into account we analyze both the cases of third party guarantees and in house guarantees we use two datasets one of christie s and sotheby s contemporary and impressionist evening sales from january 2010 to february 2012 and another larger dataset consisting of all items auctioned at christie s from 2001 to may 2011 while more expensive items are more likely to have guarantees we find little empirical evidence to suggest an effect on price from the guarantee itself once the value of the item is taken into account
