involuntary unemployment and implicit contracts this paper provides an explanation of involuntary umemployment arising as a consequence of asymmetric information between firms and workers involuntary unemployment is defined as a situation where ex post gains to trade exist a model of labor contracts is developed where the allocations are not ex post optimal it is shown that inferiority of leisure is a necessary and sufficient condition for the existence of involuntary unemployment

pressure groups and public expenditures the flypaper effect reconsidered a model of government budgeting is developed in which lobbying by interest groups can divert the allocation of funds away from the one preferred by the median voter the model is applied to state and local governments to show that the flypaper effect the tendency for lump sum grants to increase public expenditures by more than an equivalent increase in the community s pretax income can be explained without the customary assumption of voter fiscal illusion furthermore the model predicts variation in the extent of the flypaper effect among expenditure categories as found in previous empirical studies

wage employment contracts this paper studies the efficient agreements about the dependence of workers earnings on employment when the employment level is controlled by firms the firms superior information about profitability conditions is responsible for this form of contract governance under plausible assumptions such agreements will cause employment to diverge from efficiency as a byproduct of their attempt to mitigate risk it is shown that if leisure is a normal good and firms are risk neutral employment is always above the efficient level such a one period implicit contracting model cannot therefore be used to explain unemployment as a rational byproduct of risk sharing between workers and a risk neutral firm under conditions of asymmetric information

a parametrization of the auction design space abstract we present an extensive breakdown of the auction design space that captures the essential similarities and differences of many auction mechanisms in a format more descriptive and useful than simple taxonomies this parametrization serves as an organizational framework in which to classify work within the field and uncovers parameter combinations corresponding to novel mechanisms the structured characterization of auction rules can be exploited for the modular design of configurable auction servers it also facilitates the communication of auction rules to software agents enabling the automation of flexible market based negotiation journal of economic literature classification numbers c70 d44

constrainedly fair job assignments under minimum wages a number of jobs are to be assigned to a greater number of workers while having to abide by the law of minimum wages firms must determine who should be assigned which job and at what salary in such situations fair envy free allocations usually fail to exist to cope with this situation this paper proposes a new concept of fairness called constrained fairness among the set of constrainedly fair allocations the so called constrainedly fair and minimal allocations are of particular interest the reason for this is that the salaries are not only compatible with the minimum wages they are also optimal from the standpoint of cost minimizing firms and the assignment of jobs is efficient from the viewpoint of workers a convergent dynamic procedure that identifies constrainedly fair and minimal allocations is proposed furthermore strategic properties of the mechanism are derived and two notions of efficiency are evaluated

optimal labour contracts when workers have a variety of privately observed reservation wages if a firm does not know the individual ex post outside opportunities of its contracted workforce then it can use hours wages and redundancy payments to screen them will a second best contract have underemployment inefficiency or overemployment and with a stochastic contract are those workers randomly selected for layoff worse off than their retained colleagues involuntary layoff or vice versa involuntary retention the answers depend on the nature of the workers preferences two polar cases are looked at corresponding to permanent and temporary layoff the former is characterized by overemployment and involuntary retention the latter by underemployment and involuntary layoff also examined are simple contracts where all retained workers are paid a common wage and all laid off workers receive a common redundancy payment handling asymmetric information in stochastic contracts has led to two technical innovations first a number of results are proved even though all the truth telling constraints are explicitly included second a new regularity condition is found under which the local constraints are sufficient to ensure global incentive compatibility at an optimum

the dual illusion of grants in aid on central and local expenditures a reply in this journal chu chu h y 2003 public choice 114 349 359 offered corrections for inconsistencies in the logan model of dual fiscal illusion logan r r 1986 journal of political economy 94 1304 1318 this paper shows that logan 1986 introduced two prevailing models of fiscal illusion and chose to follow one of them for generalization chu has not corrected any inconsistencies he has instead offered a generalization of the other type of illusion this paper demonstrates that the chu generalization suffers from multiple irrational and unachievable results which is why logan 1986 chose the original version in the first place

optimal employment contracts with bankruptcy constraints abstract consider the optimal incentive compatible contract offered by a firm with private information to its risk averse employees if the firm is subject to a binding limited liability or bankruptcy constraint then the contract will yield underemployment in low productivity states relative to full information efficiency such contracts either yield underemployment in all states or excessively high variability in employment

liquidity flows and fragility of business enterprises abstract this paper develops a macroeconomic model in which funds are channeled to entrepreneurs through long term relationships between entrepreneurs and lenders the flow of funds to a relationship may be low causing it to break up due to insufficient liquidity multiple pareto ranked steady states emerge from complementarity between financial intermediation reflected by the number of relationships and households incentives to provide funds this complementarity also serves as a mechanism for propagating aggregate shocks financial collapse may become inescapable if a shock destroys sufficiently many relationships

using first price auctions to sell heterogeneous licenses abstract this paper considers three alternative ways to sell heterogeneous licenses via a first price format when there is single unit demand it has been suggested that incorporating a first price element may bolster competition in this case klemperer paul d 2002 what really matters in auction design journal of economic perspectives 16 169 189 in a controlled laboratory setting we compare the performance of the simultaneous first price auction the sequential first price auction and the simultaneous descending auction with that of the simultaneous ascending auction the experiments involve several bidding environments of varying complexity we find that the simultaneous ascending auction achieves the highest levels of efficiency but also has drawbacks i its revenues are low and variable ii per license profits vary and iii the incidence of winner s curse outcomes is high seller s revenues are highest when the licenses are sold in a sequential first price auction in decreasing order of quality

the dual illusion of grants in aid on central and local expenditures the purpose of this paper is to clarify some misspecificationsthat prevail in the dual illusion hypothesis which is animportant influential theory in fiscal illusion studies avoter s behavior can hence be self fulfilling and the dual illusion will not contradict each other our findings alsosupport what the dual illusion hypothesis expects that aidraises the demand for recipient government output and reducesthe demand for grantor government output the intergovernmentgrants therefore do appear to be a common source of fiscalillusion

which median voter under the median voter model the demand for local government spending is a function of the median voter income and median tax price of spending in the jurisdiction the theory provides a convenient framework for analytically aggregating the individuals public spending demands into a community public demand function it does not however provide guidance when selecting the proper definition of median income and tax share variables in empirical models data availability often dictates the selection of empirical proxies in applications but the question nonetheless remains is the appropriate empirical proxy median family income median household income or some other median income measure this paper addresses this and related questions concerning the specification of empirical expenditure functions for local governments the median voter model has proved to be an enduring device in public economics but even while it continues to be widely used in both theoretical and empirical studies of local government spending behavior the median voter model itself has become the focus of study although various specifications and modifications have been examined and compared in the literture the question of the appropriate median definition in empirical models has been overlooked thus far the usual methods of testing competing specifications in the local public spending literature is to evaluate prediction errors or the sign of key parameters in an estimated expenditure function 4 6 9 11 14 19 the nature of our question however requires a different type of test one capable of evaluating competing hypotheses that entail mutually exclusive functional forms or sets of regressors the cox test represents an appropriate procedure for evaluating the competing median definitions and related functional form questions in this paper this test based on theoretical results by cox 2 3 has several advantages in our application first the test is tractable and the statistics have well defined properties the asymptotic distribution of the calculated statistics are known thereby avoiding the use of bootstrap or other simulation methods in our evaluation second the test allows for bilateral rejection so that we

double implementation in a market for indivisible goods with a price constraint i consider the problem of assigning indivisible objects to agents in which each agent pays a price for his object and all prices sum to a given constant the objective is to select an assignment price pair that is envy free with respect to the agents true preferences i propose a simple mechanism whereby agents announce valuations for all objects and an envy free allocation is selected with respect to these announced preferences i prove that the proposed mechanism implements both in nash and strong nash equilibrium the set of true envy free allocations

fiscal illusion and the grantor government in canada recent work on the u s concludes that one or more illusions are responsible for the empirically observed flypaper effect using annual canadian data for the period 1962 84 we test the single illusion and dual illusion specifications currently in the literature while the empirical results support the dual illusion specification it is not the unambiguous choice over single illusion specifications as previously found further the nature of the grant system in canada raises questions about whether illusions or real factors produce the empirical results

price and income distortions under separate spending and taxing decisions abstract this paper analyzes the extent to which intergovernmental grants create a discrepancy between the local voter s actual and perceived budget constraints the model is innovative in that it introduces grant illusion due to income misperceptions theoretically distinguishes illusion caused by income distortions from illusion caused by price distortions and separately tests for the magnitude of each empirical analysis identifies both price and income misperceptions as significant determinants of voter behavior these unbiased estimates reveal that previous research has misspecified the budget constraint resulting in overestimation of the stimulative effects of intergovernmental grants on local expenditure

fiscal illusion and the australian local government grants process how sticky is the flypaper effect it has been argued that evidence supporting the widely documented flypaper effect is a statistical artefact more specifically that previous studies are compromised by the use of inappropriate functional forms and the endogeneity of intergovernmental grant programs whilst the first issue may be resolved with careful econometric testing the second requires the incorporation of institutional constraints into governmental expenditure equations combining australian local government expenditure equations and intergovernmental grant parameters the flypaper controversy is analysed empirical results confirm the sensitivity of the flypaper effect to specification and tests of fit unambiguously favour one functional form that specification yields no evidence of a flypaper effect in the australian institutional milieu

fiscal illusion uncertainty and the flypaper effect abstract the flypaper effect is the empirical observation that increases in intergovernmental aid stimulate greater local government expenditure than do increases in voter income fiscal illusion provides a widely accepted explanation for this asymmetry models of voter behavior under fiscal illusion typically assume that taxpayers consistently misperceive nonstochastic average for marginal tax prices this paper develops an alternative framework in which rational voters recognize marginal tax prices but must make tax and expenditure plans under imperfect information or uncertainty various sources of uncertainty are analyzed and related to the flypaper effect and implications for public expenditure demand theory are discussed

elicitation of honest preferences for the assignment of individuals to positions the problem of eliciting honest preferences from individuals who must be assigned to a set of positions is considered individuals know that they will be charged for the positions to which they are assigned a set of prices that provide no incentive for the individual to misrepresent his preferences is suggested it is shown that these prices constitute an element of the optimal solution to the dual of a linear programming assignment problem both the optimal allocation and the prices to be charged can be derived by solving two linear programming problems once preferences have been elicited the procedure can usefully be viewed as a simulation of a competitive market under conditions where such a market cannot be expected to function well it results in an efficient allocation where all resources are valued at their opportunity costs and consumer surplus is maximized its outcome thus has the desirable properties of competitive market equilibria

the role of household production in models of involuntary unemployment and underemployment a classic result in the theory of labor contracts with asymmetric information is that underemployment results if and only if leisure is an inferior good a classic result in models where unemployment occurs because of indivisibilities including implicit contract models and some equilibrium macroeconomic models is that unemployment is involuntary if and only if leisure is an inferior good the authors introduce household production into otherwise standard versions of these models and show that this implies they can have underemployment in asymmetric information models or involuntary unemployment in indivisible labor models without assuming that leisure is inferior

approximation in mechanism design with interdependent values abstract this paper studies the revenue maximization problem in environments wherein buyers have interdependent values and correlated types we show that 1 when the system of feasible sets is a matroid and buyer valuations satisfy a single crossing condition the generalized vickrey clarke groves mechanisms with lazy reserves vcg l are ex post incentive compatible and ex post individually rational 2 if in addition the valuation distribution satisfies a generalized monotone hazard rate condition the vcg l mechanism with conditional monopoly reserves is approximately optimal then we construct an ascending auction that implements the truth telling equilibrium of a vcg l mechanism in ex post equilibrium finally we discuss the connection between the vcg l mechanisms and greedy algorithms studied in lehmann et al 2002 and deferred acceptance auctions studied in milgrom and segal 2014 and the impact of competition by proving a bulow and klemperer 1996 type result

existence and characterization of optimal employment contracts on a continuous state space abstract this paper characterizes the class of incentive compatible contracts and establishes existence and absolute continuity of an optimal wage employment contract in an environment where private information can take on a continuum of values unlike previous work on optimal contracting our results use neither an assumption that utility is additively separable in income and leisure nor prior assumptions of continuity or differentiability of the contract journal of economic literature classification numbers d82 c61 j41

large indivisibles an analysis with respect to price equilibrium and fairness an exchange economy is considered in which there are a finite number of individuals the same number of indivisibles and a fixed amount of a divisible good each individual consumes exactly one of the indivisibles and a certain quantity of the divisible good the existence of prices corresponding to pareto efficient allocations is proved it is also shown that this economy possesses fair allocations income fair allocations coalition fair allocations and pareto efficient egalitarian equivalent allocations in this study the effect of including large indivisibles in an exchange economy will be analyzed the analysis will be carried out with respect to the existence of price equilibrium and with respect to the existence of different forms of fairness the economy consists of a finite number of individuals the same number of indivisibles and a fixed amount of a divisible good it is assumed that each individual consumes exactly one of the indivisibles and some quantity of the divisible good we may interpret the indivisibles as being professions or houses the relationship between price equilibrium and a pareto efficient allocation is well known and proved in a number of cases under different assumptions about preferences and commodities for a standard economy see e g debreu 5 in case of nonconvexities which may also describe a certain type of indivisibility we may have an exact relationship in economies with a continuum of individuals see e g hildenbrand 11 but otherwise an approximate relationship obtains the degree of approximation depends on the degree of nonconvexities in preferences and not on the number of individuals see e g arrow and hahn 1 we will prove the existence of prices characterizing a pareto efficient allocation in a case where the indivisibles play an essential role and where approximate results would be too approximate the indivisibles may be considered large for the individual compared to his total consumption the theory of fairness has developed considerably during the seventies different kinds of concepts of fairness have been introduced and analyzed see daniel 41 foley 81 pazner and schmeidler 121 and schmeidler and vind 141 among others normally these authors have considered models with divisible goods or an infinite number of individuals for exchange economies the existence of fair allocations an envy free and pareto efficient allocation has been proved in

cost sharing versus block funding in a federal system a demand systems approach this paper employs a maximizing framework consistent with the axioms of consumer preference to analyze local government s choice of spending on different social services within this framework it is possible to include both block funding and cost sharing intergovernment transfer schemes canada s movement to block funding from the cost sharing method of financing provincial expenditures on hospitals medical care and post secondary education is analyzed the results indicate that the provincial governments actions are generally consistent with a significant maximizing model of consumer behavior and that the change to block funding had a significant impact on real provincial funding of some previously cost shared social services

the overspending and flypaper effects of fiscal illusion theory and empirical evidence abstract this paper broadens the notion of fiscal illusion to include imperfect information where voters are unsure about how much they must pay for additional services or where they are unsure about the services received in return for higher taxes it shows how each type of voter imperfect information has different effects on public spending and modifies the overspending and flypaper effects predicted by the certainty model an empirical study of municipal expenditures provides support for the broader notion of fiscal illusion as imperfect information

transferring ownership of public housing to existing tenants a market design approach this paper explores a housing market with an existing tenant in each house and where the existing tenants initially rent their houses the idea is to identify equilibrium prices for the housing market given the prerequisite that a tenant can buy any house on the housing market including the one that he is currently possessing or continue renting the house he is currently occupying the main contribution is the identification of an individually rational equilibrium selecting and group non manipulable price mechanism in a restricted preference domain that contains almost all preference profiles in this restricted domain the identified mechanism is the minimum price equilibrium selecting mechanism that transfers the maximum number of ownerships to the existing tenants we also relate the theoretical model and the main findings to the u k housing act 1980 whose main objective is to transfer ownerships of houses to existing tenants

strategic information revelation we analyze the problem in which agents have non public information and are to play an asymmetric information game the agents may reveal some or all of their information to other agents prior to playing this game revelation is via exogenously specified certifiable statements the equilibria resulting from various revelation strategies are used to determine equilibrium revelation of information sufficient conditions are provided for complete revelation of all private information a number of examples are provided illustrating when revelation will or will not occur in commonly analyzed games many economic problems are characterized by the presence of both strategic behaviour on the part of individuals and by asymmetric information models encompassing both of these characteristics have been used successfully to examine questions in many fields usually using the concept of bayesian nash equilibrium as the solution concept typically the agents information is given exogenously and is fixed throughout the analysis modelling the information structure as static is appropriate for some problems but not for all in particular situations that are inherently dynamic most economic encounters allow for some interchange between the agents before the outcome is settled irrevocably in such circumstances it is possible that at least one or more of the agents possessing non public information may be able to reveal part or all of his information to one or all of the other agents in the economy during the course of their contact to the extent that such a communication is believed by the other agents the priors of the other agents will change and we will have what is in essence a new asymmetric information game new in

structure induced equilibria and perfect foresight expectations this paper extends the work on structure induced equilibria by explicitly considering voters expectations the standard assumption of myopic expectations is contrasted with the alternative assumption of perfect foresight expectations in the institutional setting examined perfect foresight means voters know how the outcome on the first issue in a sequence of two issues conditions majority rule outcomes on the second issue if voters act on this knowledge when voting on the first issue then several important results follow first voters may possess multipeaked preferences defined over the first issue with a majority cycle resulting so that there is no equilibrium to the whole sequence of elections second even if cycling does not result the exact location of the equilibrium involves a broader conspiracy than previously thought a conspiracy of not only preferences and institutional structure but also voters expectations as conditioned by that structure

public sector unions and public spending this study examines the influence of public sector unions on the expansion of the public sector based on public goods theory our paper models how unions influence the supply of and demand for public sector activities on the demand side public sector unions are special interests which advocate public sector expansion to policy makers on the supply side they exert pressure to maintain and expand monopoly powers empirical evidence supports the hypothesis that a positive relationship exists between public sector unionism and public spending

joint bidding in the name your own price channel a strategic analysis in this paper we study the name your own price nyop channel we examine theoretically and empirically whether asking consumers to place a joint bid for multiple items rather than bid one item at a time as practiced today can increase nyop retailers profits relatedly we also examine whether allowing consumers to self select whether to place a joint bid or itemwise bids increases retailers profits and consumers surplus we construct a dynamic model that incorporates both demand uncertainty and supply uncertainty to address these issues our theoretical analysis identifies the conditions under which joint bidding can increase both nyop retailers profits and consumers surplus we find that some consumers might bid more for the very same items when they place joint bids the increase in bid amount is related to the fact that joint bidding reduces the chance of mismatch between nyop retailers costs and consumer bids we conducted a laboratory study to assess the descriptive validity of some of the

some evidence on the effect of the separation of spending and taxing decisions it is often argued that separation of public spending and taxing decisions engenders in the voter overoptimistic hopes that someone else will bear the cost of public services thereby inducing an increase in the size of government but are perceived tax prices systematically and persistently reduced by separation although in stock markets all agents expectations may be unbiased they may or may not be unbiased in political markets this paper analyzes the separation created in federal states when the central government finances local expenditures evidence from a dynamic decisive voter model is presented that indicates that the separation introduced by federal grants to canadian provinces did in fact reduce the perceived tax price of provincial public services and raise provincial expenditures the results suggest also that the effect of separation diminished over time

fiscal illusion at the local level empirical evidence for the flemish municipalities fiscal illusion refers to a systematically biased perception of fiscal parameters due to demand side error ignorance or supply side abusive behaviour as such it is a component of a more general tax choice framework

fiscal illusion budget maximizers and dynamic equilibrium this paper extends previous work in grant induced fiscal illusion in two ways while previous models have focused on the existence of rational comparative static equilibria in the presence of illusion this work focuses on the dynamic process by which steady state equilibria can be achieved furthermore endogeneity in grants is incorporated which necessitates the use of a budget maximizing hypothesis however it is shown that a broader interpretation of the budget maximizing assumption is necessary in order for this characterization to make sense in a grantor recipient framework

do law enforcement expenditures crowd out public education expenditures as state and local governments have devoted a rising share of their resources to crime related programmes concerns have arisen that spending on other programmes such as education will fall coupled with growing public concerns over performance of the public education system and expectations that prison populations will rise as states pass and enforce more stringent sentencing laws it is not surprising that some view the expansion of crime related programmes as troublesome one hypothesis is that education and crime related programmes directly compete for government expenditures so that what one programme gains the other must lose as in a fixed pie situation a competing hypothesis is that spending on these two public programmes are unrelated and therefore higher crime related spending may also lead to higher taxes or public debt issuance or to reduction in spending on programmes other than education we estimate a three equation model of spending on crime related programmes spending on education and

the median voter model across levels of government the median voter model provides a method of aggregating individual voter s demands to obtain community demand although higher level governments are often assumed to be less responsive to voters than lower level governments it remains an open question whether or not the median voter model which has been found to apply to the lowest tier of the federalist system extends to higher level governments we use the cox specification test to find that the ad hoc model dominates the median model for counties and states the county results are sensitive to the time periods budgetary structure and degree of urbanization

the package assignment model we study assignment problems where individuals trade packages consisting of several rather than single objects although buyers reservations values are non additive efficient assignments can be formulated as a linear programming problem in which the pricing functions expressing duality may be non linear in the objects constituting the packages the interconnections among the linear programming formulation walrasian equilibrium and the core are established in the single seller auction version a necessary and sufficient condition is given for the vickrey payoff point to be implementable by a pricing equilibrium journal of economic literature classification numbers c62 d44 d51

the political determination of intergovernmental grants in australia intergovernmental grants have been conventionally explained on the basis of either equity efficiency and or institutional considerations this paper seeks to model australian intergovernmental grants by including both traditional public finance variables and public choice influences that is grants are used by federal government politicians to purchase political capital thereby enhancing their own chances of reelection the models employed in this paper are tested for six australian states for the period 1981 82 to 1991 92 using unsystematic grant transfers the results provide support for these public choice considerations and highlight the importance of incorporating institutional factors and controlling for misspecification in the error structure in estimates of this type

public education supply and student performance this paper develops a model of public exchange whereby voters and education policy makers exchange with one another within school districts because school district consolidation lowers alternatives to voters parents consolidation is hypothesized to raise public education spending because weakened intergovernmental competition allows policy makers to promote their own utility rather than that of constituents models of public education spending and academic performance are estimated over 1988 1990 while evidence indicates little support for the traditional treatment of the leviathan hypothesis that greater competition lowers public spending this paper argues that education spending by itself does not fully provide a valid test of the leviathan hypothesis since spending by itself does not necessarily indicate the quality of public education programmes empirical evidence indicates that greater numbers of schools and school districts promote higher student achievement as evidenced by higher math and v

involuntary unemployment and worker moral hazard this paper critically examines the hypothesis that layoffs are involuntary in implicit labour contracts because they are used by employers to punish inferior worker performance in repeated moral hazard situations workers typically bear risk associated with whether they are chosen to be laid off even though the latter is uninformative about previous effort choices and wages are performance contingent however the hypothesis is unsatisfactory as optimal contracts involve involuntary retentions rather than involuntary layoffs in a wide variety of circumstances the theory of implicit labour contracts as developed over the past decade has thrown considerable light on the nature of long term employment relationships by emphasizing that firm owners are usually less risk averse than workers and thus have an incentive to insure workers against fluctuations in the demand for the firm s product the theory manages to explain the emergence of long term contracts characterized by downward real wage rigidity see holmstrom 1983 however the theory also typically implies that workers will be indifferent about whether they are to be retained or laid off this runs contrary to the common observation that there is an element of involuntariness in layoff decisions i e within any job category with given skill and performance history if a proportion of randomly chosen workers are to be laid off in a recession the laid off workers would strictly prefer to be retained not only is this phenomenon of involuntary layoffs interesting to explain per se it also seems relevant to the keynesian notion of involuntary unemployment interpreted as unequal treatment of similar workers where some are employed while others are not and unemployed workers would strictly prefer to be employed it thus seems worthwhile to examine if the theory of implicit contracts can be extended to explain this phenomenon satisfactorily as a test of its plausibility and as a possible source of a consistent microfoundation for keynesian propositions to explain why the firm does not insure workers against the risk associated with selection of those to be laid off it is natural to think of possible informational asymmetries this has been attempted by geanakoplos and ito 1981 and moore 1985 geanakoplos and ito introduce the realistic feature that a firm does not observe spot market opportunities available ex post to a laid off worker this permits only incomplete insurance against the risk of layoff however their model produces the paradoxical conclusion that with decreasing absolute risk aversion workers strictly prefer ex ante being laid off moore allows workers to have better ex ante information about their spot market opportunities but finds a similar tendency toward involuntary retentions rather than involuntary layoffs in this paper we explore the alternative hypothesis that firms cannot perfectly observe effort decisions of employed workers and use the threat of involuntary layoff as a discipline device the analysis of stiglitz and weiss 1983 shapiro and stiglitz 1984 and singh 1982 of principal agent relations in the absence of demand fluctuations suggests that the threat of contract termination may be used as an incentive device in their models

a simple selling and buying procedure abstract for the assignment game we analyze the following mechanism sellers simultaneously fix their prices first then buyers sequentially decide which object to buy also each buyer may report his or her indifferences along with the previous buyers indifferences to the following buyer the first phase determines the potential prices while the second phase determines the actual matching reporting truthfully the indifferences is always a dominant strategy for the buyers moreover when buyers state their true indifferences the subgame perfect equilibria outcomes of the mechanism correspond to the maximum equilibrium price vector together with optimal matchings journal of economic literature classification numbers c78 d78

implicit contracts with asymmetric information and bankruptcy the effect of interest rates on layoffs this paper develops a model in which a firm writes labour contracts with workers and debt contracts with creditors firms have more information than do the owners of the factors of production and they are also subject to limited liability we show that if the limited liability constraint is binding then the employment level is inefficient relative to a situation of symmetric information the firm is then embedded into a partial equilibrium model in which the real rate of interest is exogenously determined we show that increases in the real rate of interest increase the inefficiency of the optimal employment contract and lead to layoffs in more states of nature than would occur at lower real interest rates recent literature in the area of implicit contracts has shown considerable interest in the assumption of asymmetric information henceforth a i papers by azariadis 1982 green and kahn 1982 and grossman and hart 1981 have all shown that a i will interfere with optimal risk sharing but although these models produce non walrasian outcomes it is not clear that they are capable of explaining the observed variations in employment over the business cycle in the absence of a link between the level of employment and other macroeconomic variables these new versions of contract theory are open to the charge that they are presenting a complicated explanation of frictional unemployment one potential link between variations in output and variations in intertemporal prices is suggested by models which explicitly allow for the possibility of bankruptcy sappington 1983 has shown that bankruptcy will generate inefficient outcomes even between risk neutral agents and farmer 1984 has shown that if sappington type contracts are incorporated into a macroeconomic structure then the resulting model predicts that bankruptcies will vary countercyclically over the business cycle although bankruptcy is important however it is unlikely that bankruptcies alone will account for all of the output loss during a recession the purpose of this paper is to show that the assumptions of a i and limited liability will generate a model in which the employment level is inefficient and in which the magnitude of this inefficiency varies systematically with the expected real rate of interest this model predicts that the observed increase in the incidence of layoffs during recessions is directly attributable to the effects of high interest rates on aggregate supply some evidence of the phenomenon to be explained is presented below

options using a collective lottery to ration vaccines during an influenza pandemic for many countries the best way to counter an influenza pandemic is to provide citizens with a pandemic vaccine however since the global supply of the vaccines is far smaller than the quantity demanded how to allocate the limited vaccines can be a very challenging task for them in this study we introduce a collective lottery mechanism that allocates vaccines as fairly as the traditional lottery while also offering more options for family members or those who are close so that they can choose the joint probability of successes that can maximize their welfare this mechanism thus gives rise to a pareto improvement over the traditional lottery our empirical study uses the us and the uk as examples in sequential collective lotteries that are simulated to prove that such an improvement while maintaining fairness in fact exists

tax effort and oil royalties in the brazilian municipalities abstract this paper estimates a stochastic production frontier to investigate whether municipalities covered by oil royalties in the last decade have reduced their tax effort in brazil the issue is relevant to the prospect of a substantial increase in these revenues and the new rules for distribution of the funds established by law no 12 734 2012 the inputs were provided by personnel and capital expenditures whereas the product was defined as the municipal tax collection with the purpose of overcoming the endogeneity problems due to reverse causality of output on inputs we used the lagged independent variable as instruments in the inefficiency equation the data set is composed of a panel of brazilian municipalities from 2002 to 2011 the results indicate that oil revenues have a negative impact on the estimated efficiencies signaling reduced fiscal effort by the benefiting municipalities

fiscal illusion intergovernmental grants and local spending islam m n 1998 fiscal illusion intergovernmental grants and local spending reg studies 32 63 71 this paper provides some evidence of fiscal illusion of a reduced tax price of public service engendered by provincial grants to local governments a model of fiscal response to grants based on expected vote maximization approach is tested on time series data as well as pooled time series and cross section data for 39 upper tier municipalities in ontario over the period 1977 91 a generalized two stage least square procedure is used to estimate the model adjusting for autocorrelation heteroscedasticity in errors and simultaneity between grants and expenditures the results show that the fiscally induced price effects of grants varies quite widely from one municipality to another and these variations can be attributed to differences in municipal characteristics and their institutional relations with the province additionally the results show evidence of considerable tax exporting and importing

state government expenditures in a federal system cost and revenue equalization effects in australia all federal systems entail some degree of fiscal equalization australia has the most comprehensive system in the world its unique feature being cost equalization the effects of this on state government behaviour are not clear the procedures used in australia for cost and revenue equalization are employed to develop a model of state government expenditures the model aims to explain both total expenditure and its allocation across types of government services the empirical results suggest that without revenue equalization state taxes would adjust to maintain current state expenditures some cost equalization effects are also found

bargaining in stationary networks we study an infinite horizon game in which pairs of players con nected in a network are randomly matched to bargain players who reach agreement are replaced by new players at the same positions in the network we show that all equilibria are payoff equivalent the payoffs and the set of agreement links converge as players become patient several new concepts mutually estranged sets partners and shortage ratios provide insights into the relative strengths of the positions in the network we develop a procedure to deter mine the limit equilibrium payoffs for all players characterizations of equitable and nondiscriminatory networks are also obtained jel c78 d85 competitive equilibrium theory assumes large and anonymous markets in which every buyer can trade with every seller underlying these assumptions are standard goods and services that may be traded at low transaction costs by agents who are not in specific relationships with one another however in many markets goods and services are heterogeneous e g cars apartments or need to be tailored to particular needs e g manufacturing inputs technical support furthermore trad ing opportunities may depend on transportation costs social relationships infor mation advertising trust technological compatibility joint business opportunities free trade agreements etc in such cases it is natural to model the market using a network where only pairs of connected agents may engage in exchange new theories are needed to explore the influence of the network structure on market outcomes many questions arise how does an agent s position in the net work determine his bargaining power and the local prices he faces who trades with whom and on what terms when are prices uniform in the network one possible conjecture is that an agent s bargaining power is determined by his relative number of connections in the network however this simple theory is implausible consider the network of four sellers located at the top nodes and nine buyers located at the bottom nodes depicted in figure 1 assume that each seller supplies one unit of a homogeneous indivisible good each buyer demands one unit of the good and all buyers have identical values for the good the buyer located in the middle has the largest number of links in the network as he is connected to each

decentralisation as an incentive scheme recent changes have introduced more decentralization in a number of traditionally centralized countries 1 in the case of france it is sometimes claimed that the 1982 1983 reform of subcentral government is of historical importance although the principles of that reform are not contested any more by the new majority elected in 1986 opinions still differ on a number of policy issues some of the issues are presented in this introductory section but the main purpose of this paper is not to expose or discuss in detail the problems of decentralization in france as argued in the second part of the introductory section the theoretical framework in which the policy issues of decentralization are usually discussed by economists is somewhat unsatisfactory in particular when applied to unitary states such as britain or france the bulk of the paper is devoted to the exploration of a different approach to decentralization it is not purported however that this approach could completely replace the more traditional one consequently when in the concluding section we return briefly to the policy issues identified here this is to be read as a preliminary attempt to evaluate the relevance of the reasoning developed in the paper

the flypaper effect identifying areas for further research the flypaper effect literature dates back three decades it is overwhelmingly neo classical in approach attempting to improve the median voter demand model and or temper it with public choice supply side perspectives whilst this approach provided valuable early substantial analytical insights more recent papers seem to have contributed only marginally to an understanding of the flypaper effect if indeed it exists at all hence as well as providing a long overdue comprehensive review of the literature on the flypaper effect this paper identifies more productive avenues for further research

renegotiating incomplete contracts i examine the welfare effects associated with having agents write incomplete contracts when contracting parties are permitted to renegotiate existing contracts i show that they will be able to design contracts that can implement the set of first best allocations via renegotiation therefore at least for the kind of economy that is examined here incomplete contracts do not impair the optimality of production and exchange

the optimal amount of discretion to allow in disclosure in this paper a party with private information can verifiably disclose some but not all of his information the optimal amount of discretion to allow the informed party is studied that is should the informed party be allowed unlimited discretion in choosing which elements of his information set to disclose or should restrictions be imposed that limit this discretion the model is formulated in the spirit of a persuasion game it is demonstrated that under certain circumstances rules that limit discretion increase the informativeness of disclosures and thus improve economic decisions

overlapping jurisdictions substitutes or complements this paper presents a simple model of the demand relationship between the activities undertaken by overlapping governments and uses the framework to estimate the relationship between municipal and county expenditures the empirical results reveal a complementary relationship between county and city general expenditures any public sector expansion effects of monopoly power at the county level will therefore be reinforced by greater municipal spending further expanding the total size of the local public sector on the other hand changes in county police and roads expenditures appear to have no strong stable impact on municipal police and roads expenditures respectively providing no reinforcing or offsetting municipal spending responses to decisions at the county level

fiscal illusion and the grantor government empirical studies indicate that unconditional intergovernmental grants have a flypaper effect several authors have modeled recipient government spending under fiscal illusion to explain this phenomenon in short grants reduce the perceived marginal cost of recipient government output this paper develops a more general model of illusion that incorporates the grantor government thereby eliminating inconsistencies encountered in previous models the more general model implies that grant finance increases the perceived marginal cost of grantor government output thus grant induced illusion should have two effects an increase in recipient output and a decrease in grantor output the empirical work supports this hypothesis

centralization and government competition this paper examines the relationship between government size and fiscal centralization with specific focus on the separate influences of centralism and fragmentation on the size of public sector in the united states the empirical findings at the national level provide support to the hypothesis that fiscal decentralization leads to a smaller government the findings at the state and local levels however show no empirical relationship between government size and the degree of centralization

how to efficiently allocate houses under price controls we examine a housing market with price controls and show how the allocation problem can be solved through a price system we demonstrate that the auction of talman and yang 2008 always generates a core allocation thus resulting in a pareto efficient and stable outcome

financial capacity and output fluctuations in an economy with multi period financial relationships this paper motivates a financial propagation mechanism in the context of an intertemporal production economy with asymmetric information and with borrowers and lenders who enter multi period financial relationships a key feature is that aggregate output and borrowers financial capacity the maximum overhang of past debt they may feasibly carry are determined jointly much in the spirit of gurley and shaw 1955 expectations of future economic conditions govern financial capacity which in turn may constrain current production especially in bad times a small but persistent shift in aggregate conditions may have a large impact on financial capacity making the framework capable of motivating large endogenous fluctuations in financial constraints understanding how small disturbances can induce large output fluctuations is an on going quest in macroeconomics this paper develops a simple framework in which shifts in aggregate economic fundamentals are amplified through their impact on financial conditions a distinguishing feature is that output and borrowers financial capacity the maximum overhang of past debt they may feasibly carry are determined jointly much in the spirit of gurley and shaw 1955 expectations of future economic conditions govern financial capacity and financial capacity may constrain current production especially in bad times a number of recent papers have resurrected the view that financial factors may play a part in propagating business fluctuations the underlying theories exploit the idea that with asymmetric information between borrowers and lenders agency costs may drive the price of uncollateralized external funds above the price of internal funds in this kind of setting a borrower s financial position is a key determinant of the terms of credit she faces in the aggregate swings in borrower balance sheets over the cycle amplify fluctuations in investment and output essentially by inducing counter cyclical movements in the required premium for external finance this simple mechanism is broadly consistent with informal descriptions of how financial and real variables interacted in the great depression bernanke 1983 and in the postwar business cycles eckstein and sinai 1986 in addition numerous recent panel data studies beginning with fazzari hubbard and peterson 1988 support the notion of a financial investment accelerator mechanism

a competitive partnership formation process a group of heterogeneous agents may form partnerships in pairs all single agents as well as all partnerships generate values if two agents choose to cooperate they need to specify how to split their joint value among one another in equilibrium which may or may not exist no agents have incentives to break up any existing partnerships or form new partnerships this paper proposes a dynamic competitive adjustment process that always either finds an equilibrium or exclusively disproves the existence of any equilibrium in finitely many steps when an equilibrium exists partnership and revenue distribution will be automatically and endogenously determined by the process moreover several fundamental properties of the equilibrium solution and the model are derived

the determinants of off budget activity of state and local governments the primary finding of this paper is that the off budget activity of the public sector is significantly and positively related to on budget activity by state and local governments we suggest the following policy implications one there appears to be evidence that the composition of total government activity is related to the relative costs of the alternative avenues of providing governmental activity future research into determining the nature of the relative cost differences may be one useful means of understanding both the composition of government activity as well as its total size two our ability to measure the true size of public sector participation in the economy must go well beyond our attempt here while we have presented information on one of the important hidden elements of public sector participation we are still a long way from effectively incorporating similar data on legislation regulations and so forth into our empirical tests further research into these issues is clearly warranted

partially verifiable information and mechanism design in a principal agent model with adverse selection we study the implementation of social choice functions when the agent s message space is a correspondence which depends on this true characteristic we characterize such correspondence for which the revelation principle is valid returns must not contradict easily observable elements of the taxpayer s lifestyle in this paper we present a model of two person organizations in which these considerations are important we ask whether the restrictions on fallacious statements inherent in the system are sufficient to achieve the goals of the organization we show that the optimal way of eliciting the agent s response may not be to establish incentives for truthtelling in all instances in our model there is one player the agent who observes the state of the economic system another player the principal takes an action based on the information presented to him by the agent this class of models is often referred to as the principal agent problem in the extensive and growing literature on this problem it has always been assumed that the agent could lie to the principal and therefore that he had to be properly motivated to act at least partially in the principal s interest our formal way of modelling the partial verifiability of information is to introduce the restriction that the agent s responses must lie in a set m o that varies with the true state 0 it is assumed that this set always admits the possibility of responding with the true state the way in which the allowable response set varies with the true state is known to the principal in other respects we retain the usual principal agent formalization in particular the principal is the stackelberg leader in this game he can commit himself to choose a collective action as a function of the message transmitted by the agent whether the variation of the message space with the true observation is purely technological or whether it is induced by the severity of potential actions of the principal

a general strategy proof fair allocation mechanism abstract this paper studies a general problem of efficiently and fairly allocating n indivisible objects like jobs or houses with a certain amount of money to n persons with a requirement that each person be assigned with one object the precise preferences of individuals over both the objects and money are unknown and manipulable but assumed to follow some general patterns to ensure the existence of a fair allocation a mechanism is developed that elicits honest preferences over both the objects and money and that assigns the objects with some money to individuals efficiently and fairly

the strategy structure of two sided matching markets we study two sided markets in which agents are buyers and sellers or firms and workers or men and women the agents are to form partnerships which provide them with satisfaction and at the same time make monetary transfers e g salaries or dowries the core of this market game is shown to have a particularly nice structure so that precise answers can be given to questions concerning comparative statics and manipulability the idea of using walrasian equilibrium as a mechanism for making allocations with desirable properties of fairness and efficiency has been studied extensively the scheme involves having agents specify their supply and demand functions the competitive equilibria are then calculated and allocations are made accordingly in general this procedure may run into two difficulties first nonuniqueness if there are several equilibria there may be no fair way to decide which one should be implemented and second manipulability if there is only one equilibrium an informed agent may be able to influence it by suitably falsifying his demand data however as we will show here using the walrasian mechanism does work remarkably well for a certain class of important markets these are the matching markets of our title and they include markets for single items like houses where it is assumed that traders do not wish to acquire more than one item they also include labor markets in which it is desired to match workers with jobs at suitable salaries academic markets in which students are to be assigned to educational institutions marriage markets where men and women are matched through negotiating of dowries it turns out that in these markets both the problems of nonuniqueness and manipulability can be resolved in a

no envy and consistency in economies with indivisible goods we consider the problem of fair allocation in economies with indivisible goods our main objective is to identify appealing subsolutions of the no envy solution we formulate desirable properties of solutions and look for solutions satisfying them given an allocation chosen by a solution for some economy and given a subgroup of the agents consider the problem of fairly distributing among its members the resources that this group has collectively received the solution is consistent if it recommends that the same bundle be attributed to each of these agents as initially we show that there is no proper subsolution of the no envy solution that satisfies consistency however many subsolutions satisfy bilateral consistency or the converse of consistency but again there is no proper subsolution satisfying these two properties together

the median voter hypothesis evidence from general purpose local governments the median voter hypothesis mvh represents a much used as well as much criticized tool in the hands of public finance economists to evaluate the mvh this paper applies the cox specification test using data from general purpose municipal governments the cox test allows for possible simultaneous rejection of the mvh and all tested models thus providing stricter criteria than applied to date in empirical mvh analyses the test results reveal that the mvh is appropriate for explaining the aggregate behavior of municipal governments but not specific services further the single service and single tax base assumptions are not critical to the empirical mvh performance

multi item auctions a collection of items is to be distributed among several bidders and each bidder is to receive at most one item assuming that the bidders place some monetary value on each of the items it has been shown that there is a unique vector of equilibrium prices that is optimal in a suitable sense for the bidders in this paper we describe two dynamic auction mechanisms one achieves this equilibrium and the other approximates it to any desired degree of accuracy

financial distress and underemployment a reasonable model of the labour market over the business cycle should predict among other things that a in very low states of product demand there may be too little employment from an efficiency perspective but as the state improves employment will increase until ultimately it is efficiently deployed and b in low states of demand a worker s welfare level will be low and as the state of the world improves so will the worker s welfare except possibly at high levels of demand where the worker s utility may start to fall surprisingly there does not exist a labour contract based model that is consistent with predictions a and b in fact the standard results in the literature are if leisure is a normal good then there will be too much employment in essentially all states of the world and the welfare of the worker declines as the state of the world improves in this paper a labour contracting model is constructed that is consistent with the above mentioned predictions two necessary ingredients in the model are the possibility of financial distress in low demand states and partial provability in contracting financial distress can be viewed as frustrating renegotiation and thus inefficient outcomes are possible in equilibrium partial provability the ability of an informed player to make verifiable claims or statements to an uninformed player eliminates certain kinds of inefficient outcomes in particular it eliminates the possibility that in equilibrium there is too much employment this last result is interesting in itself because it is commonly believed that normality of leisure necessarily implies that labour contracting models will generate employment levels that are too high from an efficiency perspective

a note on overemployment underemployment in labor contracts under asymmetric information abstract models of labor contracts under asymmetric information may predict either overemployment or underemployment this paper shows that this result depends crucially on whether or not leisure is a normal good if firms are risk neutral

implicit contracts a survey 7mplicit contracts resolve the distribution of uncertainty and utilization of specific human capital between risk averse workers and less risk averse firms incomplete contracts are required to yield involuntary layoffs in contract markets otherwise contracts are efficient and pareto optimal by construction there is a close relation between contract theory and neoclassical labor market theory contracts smooth consumption but increase the volatility of labor supply and labor utilization to demand disturbances because contractural insurance eliminates the income effects of socially diversifiable risks this result is similar to the intertemporal substitution hypothesis however the price mechanism in a contract is substantially different contracts embody a nonlinear two part pricing scheme the lump sum part allocates the income consumption consequences of risks and the marginal pricing part allocates production and labor utilization this implicit pricing mechanism is in all respects flexible though the observed average hourly wage combines both parts and may give the outward appearanceof rigidity furthermore the observed average wage rate in a contract does not reflect marginal conditions necessary for structural econometric estimation indivisibilities appear necessary to account for the split between work sharing and layoffs contracts with private information are also considered in the nonlinear pricing context this abstract was borrowed from another version of this item

fiscal decentralization and government size an extension this paper analyzes one method governments employ to circumvent the discipline of a competitive system of fiscal federalism intergovernmental collusion in the form of intergovernmental grants grants it is argued serve to encourage the expansion of the public sector by concentrating taxing powers in the hands of the central government and by weakening the fiscal discipline imposed on governments forced to self finance their expenditures the results reported suggest that intergovernmental grants do encourage growth in the public sector the results offer further support for the use of monopoly government assumptions in public sector modeling

the influence of special district government on public spending and debt growth in special district governments is examined as a reason behind public sector expansion in the united states a theoretical model is developed of the optimal mix of government suppliers which predicts how special district governments affect the overall provision of government policies the hypothesis that expansion of special district governments leads to expansion of the public sector is expirically examined over two time periods

foreign aid and the question of fungibility this paper analyzes whether the foreign assistance provided for specific categories of expenditure is shifted among them contrary to the wishes of donors it also considers whether aid reduces the tax effort of recipient governments econometric results are presented for the dominican republic that show that the fungibility of aid has resulted in a thwarting of the intentions of donors an attempt is made to account for the observed differences in behavior of individual countries in altering expenditures copyright 1993 by mit press

fair allocation of indivisible goods and criteria of justice a set of n objects and an amount m of money is to be distributed among m people example the objects are tasks and the money is compensation from a fixed budget an elementary argument via constrained optimization shows that for m sufficiently large the set of efficient envy free allocations is nonempty and has a nice structure in particular various criteria of justice lead to unique best fair allocations that are well behaved with respect to changes of m this is in sharp contrast to the usual fair division theory with divisible goods
