reserve prices without commitment abstract when potential bidders in an auction have to incur a cost to prepare their bids and thus to learn their valuations imposing a reserve price and announcing that in case no bid is submitted there will be another auction without a reserve price is both revenue and welfare improving reserve prices that induce less than maximum entry in the first auction may be optimal also entry fees are not necessarily better instruments than reserve prices journal of economic literatureclassification number d44

residential choice and the supply of local public goods abstract this paper deals with the supply of local public goods in an agglomeration consisting of a central city and a given number of suburban communities the properties of an equilibrium under free mobility are studied in particular a community s population size level of public good and public spending are analyzed as a function of distance to the central city an extension analyzes an equilibrium with two income classes and the corresponding income location pattern

note comment and letter to the editorsustainable oligopolies in this paper we show that an oligopoly market where both increasing returns to scale and competition are present can nevertheless satisfy stability conditions in a sustainable oligopoly 1 each consumer chooses the firm which proposes the price quality schedule he prefers 2 firms earn non negative profits 3 no new firm could attract consumers and make profits we prove that such a sustainable oligopoly exists under rather weak assumptions the results apply to most models of vertical or horizontal product differentiation or to models of quality differentiation due to congestion effects

resource allocation in non walrasian environments abstract we are interested in resource allocation mechanisms that perform satisfactorily in environments which are problematic for the walrasian equilibrium theory and the tatonnement the b idding process of hurwicz radner reiter is informationally decentralized and has appealing normative properties the speed of convergence of the b process is characterized in an economy with indivisible commodities a modification of this process is shown to converge in an economy with both divisible and indivisible goods some simulation results on the b process and its modifications throwing light on its performance in non walrasian environments are also reported

tiebout with politics capital tax competition and constitutional choices this paper examines how capital tax competition affects jurisdiction formation we describe a non cooperative locational model of public goods provision choices where the levels of taxation and the local public good varieties provided within jurisdictions are selected by majority voting and where equilibrium jurisdictions consist of consumers with similar tastes we show that interjurisdictional tax competition results in an enlargement of jurisdictional boundaries and even in the absence of intrajurisdictional transfers can raise welfare for all members of a jurisdiction

efficient exchange with a variable number of consumers the notion of a club efficient allocation introduced in this paper is shown to allow for a unifying treatment of rather disparate matters the main result deals with the dual characterization of such allocations the fundamental theorems of welfare economics the limit theorem on the core and a general version of a henry george theorem on the relationship between aggregate land rent and local public expenditures all can be recovered as special cases of this paper s main result

second best taxation as a game second best theory usually lies in the realm of normative analysis it focuses attention on the best solutions which still can be obtained in problems where constraints of various natures forbid the attainment of first best pareto optimal situations its central concern is the characterization of such second best solutions and a large part of the literature concentrates on the optimal design of taxes or of policies of public firms taking a second best problem we try in this paper to shift the emphasis from normative to positive considerations the solution we are interested in is not optimal with respect to some a priori given social welfare function embodying justice objectives but it is supposed to reflect the power of the different agents in a negotiation process clearly the conceptual tools required for such an analysis are to be found in game theory and it is actually a game theoretical approach that we follow here the model we are looking at is presented in section ii it formalizes one of the simplest second best problems that can be imagined we have a twogood economy with one private good and one public good agents have different wealth in private good and the public good is financed through a wealth tax this latter fiscal system is clearly not flexible enough to adjust contributions with marginal willingnesses to pay so that we actually face a second best situation there is one decision variable in the society the tax rate which determines the public good production about which the agents have conflicting desires to this problem we associate a game which provides a precise framework for the analysis of the power of the agents the positive outcomes of the negotiation process are supposed to belong to the core of this game sections iii and iv concentrate on the analysis of the core the results strongly contrast with those obtained in the classical studies of the core of 67 0022 053 l 81 040067 25 02 00 o

equilibrium in a finite local public goods economy abstract this paper examines the existence of a noncooperative equilibrium in a finite local public goods economy where consumers have quasi linear preferences jurisdictions consist of consumers who chose the same public project and finance the cost of production of public goods through either a proportional income tax or a poll tax we show that under a proportional income tax scheme a nash equilibria may fail to exist under a poll tax scheme an equilibrium always exists but in general nash equilibria violate a very weak efficiency condition we conclude by commenting on the stabilizing effect of zoning policies journal of economic literatureclassification number c71

political institutions and sorting in a tiebout model we construct a computational model of tiebout competition and show that political institutions differ in their ability to sort citizens effectively in particular we find that certain types of institutions those that become more politically unstable as citizen heterogeneity increases perform relatively poorly given a single jurisdiction yet these same institutions perform relatively well when there are multiple jurisdictions we provide an explanation for this phenomenon which draws upon simulated annealing a discrete nonlinear search algorithm jel

quantities qualities and multiple public services in the tiebout model abstract this paper introduces a new more realistic characterization of local public services this characterization fits education parks and streets none of which are a pure samuelsonian good it is shown that tiebout s hypothesis holds for this new type of services provided correct user charges are adopted introducing several local services considerably affects the results the paper emphasizes the difference in tastes with regard to quality as opposed to quantity earlier literature is shown to apply to the role of quality and ignores the role of quantity the effect of the latter makes mixed communities more efficient than segregated ones it is shown that efficient allocation with mixed communities is an equilibrium in a costless mobility tiebout type setting

an efficient dynamic auction for heterogeneous commodities this paper proposes a new dynamic design for auctioning multiple heterogeneous commodities generalizing earlier work that treated identical objects an auctioneer wishes to allocate one or more units of each of k heterogeneous commodities to n bidders the auctioneer announces a vector of current prices bidders report back quantities demanded at these prices and the auctioneer adjusts the prices units are credited to bidders at the current prices as their opponents demands decline and the process continues until every commodity market clears bidders rather than being required to behave as price takers are permitted to strategically exercise their market power nevertheless with pure private values the proposed auction yields walrasian equilibrium prices an efficient outcome results as from a vickrey clarke groves mechanism but bidders are only required to evaluate their demands along a one dimensional path of prices rather than reporting their utilities over the entire k dimensional consumption set the auction is also more transparent and potentially simpler for bidders to understand and has the advantage of assuring the privacy of the upper portions of bidders demands theoretically the new auction provides a new foundation for convergence to walrasian equilibrium in an exchange economy practically it provides an efficient method for simultaneously auctioning two or more related types of securities for example three month and six month treasury bills it is also potentially useful for auctioning multiple types of communications spectrum for example licenses for paired and unpaired spectrum

economic theories of the break up and integration of nations abstract this paper surveys the recent political economy literature on the size distribution of nations the main themes of this literature are 1 a the spread of democracy leads to the creation of too many sovereign states 2 b the extent of factor mobility plays a key role in determining the incentives towards separation or integration 3 c economic integration through the development of international trade may require greater political integration to create and effectively maintain a level playing field in international trade at the same time economic integration by reducing the economic costs of separation increases the incentives towards political separation

alternative common value auction procedures revenue comparisons with free entry the logic of revenue comparisons for different types of common value auctions is substantially altered if the number of participants rather than being fixed responds endogenously to the expected profitability from participating in a thoroughly symmetric model a seller may prefer that competition be indirect an auction procedure in which fewer participants are needed to drive the expected profitability from participating down to the level obtainable in other auctions in the economy can attain higher expected revenue if a sale is sufficiently likely this insight allows a complete revenue ranking of standard auction procedures with endogenous entry

the consequences of overlapping tax bases for redistribution and public spending in a federation tax and expenditure policies are studied in a federation with imperfectly mobile households states implement a linear progressive tax and supply a public good a vertical fiscal externality reflecting the effect of state policies on federal revenues provides an incentive for state taxes to be too progressive a horizontal fiscal externality causes nonoptimal state taxes and expenditures because of the migration effect the federal government implements its own linear progressive tax and makes transfers to the states the federal government can nullify both externalities by appropriate fiscal policies and redistributive taxation can be decentralized to the states c 1998 elsevier science s a

local public goods with mobility existence and optimality of a general equilibrium abstract the existence and optimality of a general equilibrium in a model with a finite number of locations among which the continuum of individuals each individual belonging to one of a finite number of types have to choose is investigated each community finances its own production of public goods by taxes the way in which the tax burden in shared among the different types in the different regions is left arbitrary the model allows for restrictions on the mobility of either residents and or workers congestion and externalities in both production and consumption commuting costs preferences of an individual may also depend on his location as well as on the distribution of all individuals across locations

on optimal reservation prices in auctions the theory of auction design examines how various factors affect the outcome of an auction most of the existing literature focuses on how varying the amount of information available to each bidder affects the bid taker s expected revenue when all other factors remain constant this paper studies how the bid taker s expected revenue varies with changes in the auction format when such changes affect the number of bidders and in turn the bidders maximum value for the object being sold specifically we examine how varying the reservation price or screening level affects the bid taker s expected revenue though its effect on the number of bidders for two simple examples the losses associated with a reduced number of bidders outweighs any benefits that nontrivial reservation prices might have had in models with an exogonously set number of bidders

do local governments use their tax bases efficiently abstract this paper analyzes an economy with multiple governments and with mobility of individuals across jurisdictions where each government is constrained to raise revenue for public expenditures using distortionary taxes a government is said to be competitive if the total benefits and costs of its decisions including the excess burden are perceived to be internalized the competitive equilibrium allocations are not constrained efficient in general there exists another set of distortionary taxes and public expenditures such that when private sector behavior adjusts to maintain equilibrium all individuals in the economy are better off thus competitive decentralized decision making does not lead to an efficient use of the available tax instruments it is also shown that the source of the failure can be interpreted as a missing market and the form of the best decentralized remedy which involves pricing the tax base is derived

on a possible benefit to bid takers from using multi stage auctions each year multi stage auctions of one form or another sell or let billions of dollars worth of goods and contracts yet despite the significance of such auctions the existing theory of auctions and competitive bidding fails to explain why a bid taker might prefer a multi stage auction to a possibly simpler single stage mechanism in fact the existing theory tends to overlook multi stage mechanisms altogether this paper takes a first step in correcting that omission we start with several illustrations of what we will define to be multi stage auctions all the illustrated auctions allow bidders to acquire information or more generally to increase the amount of resources committed to bidding in stages we conjecture that allowing such a sequential commitment of resources could result in a more efficient auction than if bidders had no chance to adjust their commitments an analytic example illustrates and documents the benefits to the bid taker from using a multi stage auction in the example bidders acquire costly information in stages a bidder may stop acquiring additional information as soon as further participation in the auction would no longer increase his expected net profit the resulting auction generates significantly more expected revenue for the bid taker than if the bidders all had to acquire the same amount of information

property taxes and property values evidence from proposition 212 abstract we examine the effect of proposition 2 1 2 on revenues and housing prices in massachusetts communities that were initially constrained by the law saw large increases in state aid and the use of fees we use these initial constraints as instruments for changes in other components of revenue while treating the change in the property tax as exogenously determined by proposition 2 1 2 our results strongly suggest that communities that were able to increase their property taxes more rapidly saw greater increases in their housing values in the period following passage of the law

supply and equilibrium in an economy with land and production a model with a finite number of consumers trading in land that can be changed through production is examined unlike most other models in urban economics land is modeled as measurable subsets of a compact set formally there are three major results conditions are found under which a solution to the producer s profit maximization problem exists secondly conditions are found under which a solution to the consumer s problem exists the assumptions used to prove these two results are standard finally the existence of an equilibrium is demonstrated copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

tatonnement beyond gross substitutes gradient descent to the rescue abstract we identify a class of economies for which tatonnement is equivalent to gradient descent this is the class of economies for which there is a convex potential function whose gradient is always equal to the negative of the excess demand among other consequences we show that a discrete version of tatonnement converges to the equilibrium for the following economies of complementary goods i fisher economies in which all buyers have complementary ces utilities with a linear rate of convergence in fisher economies all agents are either buyers or sellers of non numeraire goods but not both this shows that tatonnement converges for the entire range of fisher economies when buyers have complementary ces utilities in contrast to prior work which could analyze only the substitutes range together with a small portion of the complementary range ii fisher economies in which all buyers have leontief utilities with an o 1 t rate of convergence

strong tiebout equilibrium under restricted preferences domain abstract we investigate the existence and give a partial characterization of a strong tiebout equilibrium which consists of an endogenously formed partition of the individuals into disjoint jurisdictions with each jurisdiction producing and financing its own public goods and moreover there exists no group of individuals who can all benefit by establishing their own community in particular no single individual finds it desirable to migrate from his equilibrium jurisdiction the existence proof makes use of the notion of consecutive games which we introduce and show that for such games there always exists a partition with a nonempty core

pigou tiebout property taxation and the underprovision of local public goods abstract pigou s proposition that the use of distorting taxes rather than neutral head taxes reduces public service levels is examined in this paper a simple model with a national system of competing local governments is utilized to demonstrate that the use of a distorting property tax on mobile capital decreases the level of residential public services the case where public services are an intermediate producer good is also considered

distributive implications of european integration one of the main pitfalls of european construction is undoubtedly the alleged charge that it impedes redistributive policy at the national level this charge is indeed widespread in political circles and in the medias yet it had received little attention among economists up to recently over the last few years an increasing amount of research has been devoted to that accusation or to be more neutral to that conjecture the purpose of our paper is to survey this literature we first present the conventional wisdom according to which mobility makes redistribution difficult if not impossible we also discuss the most important qualifications to this result and the solutions that are generally advocated and that imply some sort of cooperation in a second part we consider a different issue that of redistribution across countries it assumes the existence of some supranational government which is not trivial in addition informational differences between the national and the supranational governments are shown to play a crucial role

a critique of tiebout s theory of local public expenditures the last section of this paper presents a rigorous version of tiebout s theory of local public goods it is shown that equilibria exist and are pareto optimal this rigorous theory follows closely the more rigorous part of tiebout s work this rigorous theory makes a number of very special assumptions which make local public goods essentially private the body of this paper presents a series of examples which show that if one tries to generalize the rigorous version of tiebout s theory in a number of interesting directions then equilibria may no longer exist or may not be pareto optimal the conclusion is that tiebout s idea does not lead to a satisfactory general theory of local public goods the goal of this paper is to point out that tiebout s notion of equilibrium with local governments does not have the nice properties of general competitive equilibrium except under very restrictive assumptions tiebout 39 suggested that there are competitive forces which tend to make local governments allocate resources in a pareto optimal fashion consumers choose to live in those towns with the mix of taxes and public goods they prefer local governments choose this mix so as to attract inhabitants this idea may seem intriguing for it suggests that the invisible hand solves an important part of samuelson s perplexing public goods problem 32 tiebout in fact makes an argument which is nearly rigorous i give a rigorous version of his argument at the end of the paper however in this rigorous version so many restrictive assumptions are made that public goods become essentially private in the body of the paper i give a series of examples with which i try to convince the reader that one is forced to adopt tiebout s restrictive assumptions the idea is that if one changes any of his assumptions then either equilibria may not exist or may not be pareto optimal my examples are presented in the context of a general class of tiebout models i consider several subclasses one of which is the special case considered by tiebout in each of the subclasses except that considered by tiebout i give a counterexample either to the existence of equilibrium or to its pareto optimality the subclasses are so chosen that the difficulties they reveal would be shared by any reasonable tiebout model which differed from his special case i believe that my examples controvert tiebout s suggestion 39 last paragraph that his theory compares favorably with competitive equilibrium theory most of the examples in this paper have already appeared in the literature i cite related work as i go along what is new here is that i assemble the examples in a unified argument

assessing the importance of tiebout sorting local heterogeneity from 1850 to 1990 this paper argues that long run trends in geographic segregation are inconsistent with models where residential choice depends solely on local public goods the tiebout hypothesis we develop an extension of the tiebout model that predicts as mobility costs fall the heterogeneity across communities of individual public good preferences and of public good provision must weakly increase given the secular decline in mobility costs these predictions can be evaluated using historical data we find decreasing heterogeneity in policies and proxies for preferences across i a sample of u s municipalities 1870 1990 ii all boston area municipalities 1870 1990 and iii all u s counties 1850 1990

accountability and decentralisation in government an incomplete contracts model this paper approaches the question of the appropriate level of decentralisation of power in government as a problem in the allocation of control rights under incomplete contracts the model of the paper compares allocations of power to local central and regional government as alternative means of motivating governments to act in the interests of citizens centralisation allows benefits from policy coordination but has costs in terms of diminished accountability which can be precisely defined as the reduced probability that the welfare of a given region can determine the re election of the government the model is extended to allow for conflicts of interest within regions and externalities between central and local governments in a federation it is also applied to determining levels of fiscal transfer between localities and to circumstances where governments may act as leviathans appropriating resources for their own use

local government structure and urban residential location the large research literature on the tiebout model has developed with little attention paid to the urban economic structure in which local government functions this paper attempts to examine the theoretical consequences of local jurisdictions functioning within a conventional monocentric urban model it also discusses a mathematical formulation of a two jurisdiction linear city in which the local service level and local property tax rate might be used as strategic variables in a game theory sense it is concluded that for this to happen the local service level has to have more than one element which is intuitively appealing some references are developed to current british local government and possible changes

clubs and the market large finite economies abstract this paper builds a general equilibrium model of finite economies with exchange and club formation agents trade multiple private goods widely in the market can belong to several clubs and care about the characteristics of other club members because club memberships are indivisible and choices of club memberships must be coordinated across the population the core of such an economy may be empty and equilibrium may not exist however for large finite club economies an approximate core is not empty and states in this approximate core can be approximately decentralized by prices for private goods and for club memberships the arguments use convexification tools familiar from the literature on private goods economies and a new tool of some independent interest that addresses the special problems created by the nature of club memberships journal of economic literature classification numbers d2 d5 h4

household location and tiebout do families sort according to preferences for locational amenities abstract if households sort efficiently across locations then at a given location families receive the same marginal benefit from the locational amenities we test for such sorting by imposing cross equation restrictions on hedonic regressions that difference away location versus house specific effects estimates are obtained using a unique subset of the american housing survey in which adjacent housing units are grouped together and observed in both 1985 and 1989 rejection of the cross equation restrictions unambiguously implies an inefficient sorting of households in contrast the data support the cross equation restrictions which is a necessary but not sufficient condition for efficient sorting

tiebout sorting and neighborhood stratification tiebout s classic 1956 paper has strong implications regarding stratification across and within jurisdictions predicting in the simplest instance a hierarchy of internally homogeneous communities ordered by income typically urban areas are less than fully stratified and the question arises how much do departures from standard tiebout assumptions contribute to observed within neighborhood mixing this paper quantifies the separate effects of employment geography via costly commuting and preferences for housing attributes on neighborhood stratification it does so using an equilibrium sorting model estimated with rich census micro data simulations based on the model and credible preference estimates show that counterfactual reductions in commuting costs lead to marked increases in racial and education segregation and to a lesser degree increases in income segregation given that households now find it easier to locate in neighborhoods with like households while turning off preferences for housing characteristics increases racial segregation especially for blacks doing so reduces income segregation indicating that heterogeneity in the housing stock serves to stratify households based on ability to pay further we show that differences in housing help to accentuate differences in the consumption of local amenities

tiebout economies with differential genetic types and endogenously chosen crowding characteristics abstract we consider a tiebout economy with differential crowding and public projects in which agents are distinguished by their tastes and genetic endowments agents choose which crowding characteristic for example a skill they wish to express and this affects their value to other members of their jurisdiction club firm etc an agent s choice is influenced both by his genetic endowment which affects his cost of acquiring crowding characteristics and by his preferences over which crowding characteristic he expresses we show that if small groups are strictly effective the core is equivalent to the set of anonymous competitive equilibrium outcomes but that the core generally contains taste homogeneous jurisdictions journal of economic literature classification numbers h41 h72

towards european monetary union without the ems towards emu without the ems paul de grauwe this paper examines the causes of the breakdown of the ems arguing that ems credibility has always been impaired by recessions this has relevance both for the future of monetary union in europe and for the path by which it might be attained i argue that in comparison with the erm the present more flexible exchange rate arrangements will ease not exacerbate some of the technical problems in making the transition to emu i then analyse the political economy of monetary union and identify the main stumbling blocks that remain finally i set out a specific proposal that takes advantage of the new opportunities to move forward towards emu

equivalence of the core and competitive equilibrium in a tiebout economy with crowding types abstract we propose a new model of a local public goods economy with differentiated crowding the new feature is that taste and crowding characteristics of agents are distinguished from one another we prove that if the economy satisfies strict small group effectiveness then the core is equivalent to the set of tiebout equilibrium outcomes equilibrium prices are defined to depend solely on crowding characteristics this implies that only publicly observable information and not private information such as preferences is needed to induce agents to sort themselves into efficient jurisdictions thus our model allows us to satisfy bewley s 6 anonymity requirement on taxes in his well known criticism of the tiebout hypothesis

a convergent price adjustment process abstract in this paper we describe a price adjustment mechanism which leads to an economic equilibrium starting from an arbitrarily chosen initial price vector the process is global and universal

incomplete information high low bidding and public information in first price auctions high low bidding refers to auctions of a series of objects where for a subset of the auctioned objects one of two buyers bids high on some objects and low on others while the other buyer does the reverse this paper shows that high low bidding does not imply collusive behavior among buyers in particular through a formal modeling of a noncooperative game of information acquisition and bidding decisions it shows that high low bidding can be obtained the paper also demonstrates that if the cost of information to a seller is less than the equilibrium joint expected information cost of the buyers then it pays the seller to provide public information finally if the provision of public information is not feasible but a seller can know whether buyers have acquired information then it pays the seller to make known to the buyers and to pursue a policy that just prior to the start of an auction the seller will announce which buyer has acquired information
