the public choice of superior sanctions this paper analyzes the public choice of specific forms of sanctions current sanctions are essentially quantity constraints q sanctions which are like quotas in that they might bestow benefits on certain special interest groups in the target country revenue sanctions r sanctions may be able to recapture such benefits in the form of sender government revenue which could either compensate for the costs of sanctions to the sending country or finance other sanction enhancing activities aimed at the target country hence r sanctions may be superior to q sanctions in general or on the basis of target efficiency however public choice analysis suggests that q sanctions will generally be chosen over r sanctions by democratic countries

durable goods and product obsolescence the issue of product obsolescence is addressed by examining the optimal sales strategy of a monopolist firm that may introduce an improved version of its current product consumers expectations of a forthcoming product lowers the price that they are willing to pay for the current product because of its loss in value due to obsolescence the new product is characterized by consumers increased willingness to pay and by its competitive interaction with the old product these characteristics affect the tradeoff that the firm makes between the cost of waiting for new product sales versus the cost of cannibalizing these sales we analyze the effect of these characteristics of the new product on the firm s optimal sales strategy we consider the various policy measures available to the firm including limiting initial sales in order to lower cannibalization of the new product buying back the earlier version of the product in order to generate greater demand for the new product and announcements of future product introductions we find that for modest levels of product improvement the firm s optimal policy is to phase out sales of the old product while for large improvements a buy back policy is more profitable lastly we find that the firm is better off if it informs consumers whether a new product is forthcoming

the relative restrictiveness of tariffs and quotas a reinterpretation from a rent seeking perspective international trade theorists have conventionally argued that a tariff is a less inefficient method of restricting imports than quotas as peter kenen writes tariffs are better instruments than most other trade controls 1 the purpose of this short article is to develop two fundamental points first contrary to the common presumption government limitations on imports will be more restrictive under a tariff system than a quota system that is to say fewer cars will be imported from japan under a system of import tariffs than quotas or what amounts to the same thing voluntary restraints second the relative efficiency of quotas and tariffs cannot be fully settled by way of the apriori arguments used in the past however we might still reasonably conjecture that tariffs will be more inefficient at least as measured by the extent of the deadweight loss than quotas these conclusions unfold from a rent seeking perspective

equilibrium properties of auctions and alternative procedures for allocating transferable permits abstract this paper examines the equilibrium properties of a range of auctions and related procedures placing emphasis on the types of procedures that are likely to be of special interest in environmental management applications nash equilibrium properties are first derived for a very general class of auctions for multiple homogeneous or heterogeneous objects or permits next it is shown that given appropriate assumptions three broad classes of public allocation procedures that do not generate revenues for the government would yield participants equal expected profits these classes are 1 incentive compatible auctions where bidders receive equal lump sum refunds 2 non incentive compatible procedures where refunds are a function of participants bids and 3 free initial distribution of permits on a lump sum basis followed by trading via a competitive market the applicability of the general results is then demonstrated by examining the particular non incentive compatible fair division procedure originally suggested by knaster finally implications of the theoretical results for applications including the allocation of transferable discharge permits and water rights are discussed

the role of firm size in bilateral bargaining a study of the cable television industry we examine the effect of buyer merger on bilateral negotiations between a supplier and n buyers merger may have bargaining effects in addition to the usual efficiency effects the effect of merger on the buyers bargaining position depends on the curvature of the supplier s gross surplus function merger enhances worsens the buyers bargaining position if the function is concave convex based on a panel of advertising revenue in the cable television industry our estimates indicate that the gross surplus function for suppliers of program services is convex this result suggests that cable operators integrate horizontally to realize efficiency gains rather than to enhance their bargaining position vis a vis program suppliers

durable goods monopolists durable goods monopolists face special problems because the sale of their products creates a secondhand market not controlled by the monopolist to the extent the monopolist is able to rent his product rather than sell it or to make binding promises about his future production such problems are ameliorated given the inability to do the above the monopolist is led to producing goods less durable than those produced by either competitive firms or monopolist returns a reverse averch johnson result that monopolist sellers may invest less in fixed costs including plant modernization and research and development than would the renters is shown it is also shown that even though sellers have less monopoly power than renters and nondurable goods monopolists it is possible that the seller will cause a greater deadweight loss than the other types of monopolies

estimating demand for local telephone service with asymmetric information and optional calling plans in this paper i study the theoretical and econometric implications of agents uncertainty concerning their future consumption when a monopolist offers them either a unique mandatory nonlinear tariff or a choice in advance from a menu of optional two part tariffs agents uncertainty is resolved through individual and privately known shocks to their types in such a situation the principal may screen agents according to their ex ante or ex post type by offering either a menu of optional tariffs or a standard nonlinear schedule the theoretical implications of the model are used to evaluate a tariff experiment run by south central bell in two cities in kentucky in 1986 the empirical approach explicitly accounts for the existence of informational asymmetries between local telephone users and the monopolist leading to different nested econometric specifications under symmetric and asymmetric information the empirical evidence suggests that there exists a significant asymmetry of information between consumers and the monopolist under both tariff regimes all expected welfare components failed to increase with the introduction of optional tariffs for the estimated value of the parameters copyright 2002 wiley blackwell

economic and political determinants of budget deficits in developing countries abstract the evidence from a large sample of developing countries tends to reject the empirical implications of optimizing models of the process of determination of fiscal deficits tax rates seigniorage and inflation the paper also presents some preliminary evidence that an important reason for the failure of the equilibrium approach to fiscal policy is that fiscal deficits are partly determined by political factors and that cross country differentials in budget deficits may depend on measures of political instability in particular as suggested by a number of recent theoretical approaches an increase in the degree of political instability appears to lead to greater budget deficits

tax base variability and procyclical fiscal policy in developing countries abstract based on a sample of 56 countries we show that fiscal policy in the g7 countries appears to be acyclical while fiscal policy in developing countries is procyclical i e fiscal policy is expansionary in good times and contractionary in bad times to explain this puzzle we develop an optimal fiscal policy model in which running budget surpluses is costly because they create pressures to increase public spending given this distortion a government that faces large fluctuations in the tax base as is the case for developing countries will find it optimal to run a procyclical fiscal policy

symbiosis vs crowding out the interaction of formal and informal credit markets in developing countries abstract it is a common observation in many developing countries that enterprises are active borrowers in both formal and informal credit markets we propose a model in which the formal sector s superior ability in deposit mobilization is traded off against the informational advantage that lenders in the informal sector enjoy the formal sector can screen borrowers by providing only partial financing for projects thereby forcing borrowers to resort to the informal sector for the remainder of the loan we use the model to predict how the market structure responds to changes in the environment and we consider the policy implications of various forms of government intervention

tax compensation schemes misleading advice in a rent seeking society the central message of this paper was captured by kipling when he wrote of the dane s conquest of his country more than a thousand years ago he added to the passage at the head of the paper qu and that is called paying the dane geld but we ve proved it again and again that if once you have paid him the dane geld you never get rid of the dane

hiring and leasing with nonlinear prices this paper examines the problem of a monopolist setting an optimal nonlinear pricing schedule in the face of consumers of unknown type who arrive randomly over time and self select a choice of hire period the major determinant of pricing policy is the customer arrival distribution with the overall level of price higher than in the atemporal yield management nonuniform pricing solution by a margin which increases with the average frequency with which potential customers arrive by contrast the solution is generally fairly insensitive to variations in the time rate of discount although there is a tendency for the rate of price discount to increase with increases in the time discount rate

the neo luddite s lament excessive upgrades in the software industry we examine two reasons why a monopoly supplier of software may introduce more upgrades than is socially optimal when the upgrade is backward but not forward compatible so users who upgrade reduce others network benefits one explanation involves a commitment problem profits and social welfare may suffer because ex post the monopolist will want to sell the upgraded product to new consumers the second involves consumer heterogeneity here oversupply arises from the difference between the externality that upgrades impose on the marginal and average consumer and from the effect of upgrades on sales of the base good

cyclicality of taxes and external debt abstractin their work vegh and vuletin have shown that statutory tax rates are acyclical in developed economies and procyclical in developing ones this article extends their analysis by checking the interaction of statutory tax rates with countries external public debt in general we found that the value added tax rates are changed procyclically in both developed and developing countries i e taxes are raised in bad times and reduced in good times however when the external debt is high in the developing countries the procyclicality increases while the opposite result holds for developed economies this pattern occurs mainly in times of recession when the need for loans is the highest although we found that there was a reduction in procyclicality after the 2000s these findings pose a challenge to policy makers who should think of ways of dealing with lack of foreign funds in difficult times

revenue implications of money creation under leviathan most governments possess a monopoly franchise in the creation of money economists provide an analytical justification for this institutional arrangement either in terms of the use of monetary aggregates for macro economic stabilization or in terms of the alleged inability of competitive markets to generate tolerably efficient monetary results any complete case for the government s monetary monopoly must however depend on a comparison of market and political arrangements a comparison that requires predictions about how governments are likely to behave once a monopoly franchise is assigned similarly such predictions are crucial in evaluating restrictions that might be imposed on the government s exercise of its money creation power in designing a monetary constitution in the analysis of political arrangements the revenue implications of the money creation power are probably more significant than considerations of either macro economic stability or optimality in the money supply although those revenue implications are incidental to demonstrating the nature of market failure in monetary arrangements they are fundamental in understanding how the government might exploit a monopoly in money creation once granted our interest in the revenue effects of money creation stems from a broader study of constitutional restrictions on the revenueraising authority of government see our book the power to create money is naturally encompassed in this restrictions on the revenue raising power must embody restrictions on the power to create money consequently the fiscal constitution has important implications for the monetary constitution in this paper we examine both the revenue implications of money creation and desirable consitutional restrictions on the money creation power within the context of a specific model of political processes

optimal labour contracts under asymmetric information an introduction the review of economic studies has instituted a new series of lectures to be given annually by a younger british economist at the association of university teachers of economics meetings the choice of lecturer is determined by a panel whose members are currently professors hahn mirrlees and nobay this paper is a revised version of the first lecture in the series it was presented at the aute meeting held at the university of surrey in april 1982 and was refereed in the usual way mak

monopoly with incomplete information recent theoretical research on principal agent relationships has emphasized incentive problems that arise when the parties involved are constrained by either asymmetric information or their inability to monitor each other s actions here we concentrate on the former constraint and consider the case of a single principal the monopolist the main contribution is to show that under a separability assumption strong conclusions can be drawn about the nature of optimal incentive schemes although the primary focus is on optimal quantity discounts in a monopolized market the results also shed light on related topics such as optimal income taxation and commodity bundling

optimal nonuniform prices we consider optimal nonuniform pricing schedules where the price depends upon the amount purchased such schedules are regularly used by public utilities and other services welfare optimal nonuniform prices are related to the theory of optimal uniform prices developed by ramsey we characterize situations in which upward or downward discontinuities in pricing schedules are optimal our results are applicable to a number of related problems including optimal taxation insurance and incentives economic theory has confined most of its attention to markets with uniform prices in which the price per unit charged is invariant to the level of a customer s purchases this focus is warranted when goods are resellable since any attempt to charge nonuniform prices could be circumvented by reselling amongst customers but when goods are not resellable nonuniform prices are not only possible but common public utilities have declining block pricing with lower unit charges for large levels of consumption many agencies providing services including communications transportation even education use two part pricing with a fixed entry or retainer charge and a further charge per unit consumption nonuniform price schedules can be expected to be ever more common as services become a larger fraction of total output the increasing prevalence of nonuniform pricing policies have made them the focus of recent public and economic attention oi 1971 feldstein 1972 and ng and weisser 1974 have examined optimal two part pricing policies leland and meyer 1976 examine block pricing and show by example that optimal welfare policies may require nonuniform prices if zero profit constraints are binding in this paper we consider arbitrary nonuniform pricing policies using variational techniques two part and block pricing schedules are of course special cases of the environment we consider the work most closely related to our examination is the seminal paper by spence 1978 and subsequent analysis by roberts 1979 spence however does not pay explicit attention to the key role played by constraints on optimal pricing schedules roberts considers upward price discontinuities which lead to bunching of consumers at a given level of consumption but not downward price discontinuities which lead to regions in which no consumer chooses to consume gaps bunching or gaps may appear in the optimal price schedule even when underlying demand and cost functions are smooth and well behaved the prevalence of discontinuous pricing schedules e g the block pricing structures of public utilities argues that these questions are of practical as well as theoretical interest

cost functions in non linear pricing abstract this paper compares the optimal selling strategies with symmetric and asymmetric information when monopolist s cost function depends both on individual and aggregate production we show how standard underproduction and higher exclusion with incomplete information are affected

the simple economics of extortion evidence from trucking in aceh this paper tests whether the behavior of corrupt officials is consistent with standard industrial organization theory we designed a study in which surveyors accompanied indonesian truck drivers on 304 trips during which they observed over 6 000 illegal payments to police soldiers and weigh station attendants using plausibly exogenous changes in the number of checkpoints we show that market structure affects the level of illegal payments we further show that corrupt officials use complex pricing schemes including third degree price discrimination and a menu of two part tariffs our findings illustrate the importance of considering the market structure for bribes when designing anticorruption policy

fiscal federalism and procyclical spending the cases of argentina and brazil este trabajo estudia las fuentes de la prociclicalidad del gasto para gobiernos subnacionales en argentina y brasil encontramos que los esquemas de coparticipacion de los impuestos explican solo una parte menor de la prociclicalidad de los recursos de las entidades subnacionales siendo la mayor parte explicada por la prociclicalidad de los propios recursos esto es especialmente visible cuando esa prociclicalidad se mide relativa al producto de cada entidad subnacional usando evidencia de corte transversal para distintas jurisdicciones podemos concluir que a su vez la prociclicalidad del gasto resulta de la prociclicalidad de los recursos mediante el llamado voracity effect la conclusion es que el debate sobre la prociclicalidad del gasto de entidades subnacionales debiera concentrarse mucho mas en mejorar los sistemas impositivos locales que en cambiar los regimenes de coparticipacion

when are local incentive constraints sufficient we study the question of whether local incentive constraints are sufficient to imply full incentive compatibility in a variety of mechanism design settings allowing for probabilistic mechanisms we give a unified approach that covers both continuous and discrete type spaces on many common preference domains including any convex domain of cardinal or ordinal preferences single peaked ordinal preferences and successive single crossing ordinal preferences local incentive compatibility suitably defined implies full incentive compatibility on domains of cardinal preferences that satisfy a strong nonconvexity condition local incentive compatibility is not sufficient our sufficiency results hold for dominant strategy and bayesian nash solution concepts and allow for some interdependence in preferences

a reduced form optimal nonlinear income tax problem abstract for a finite population with quasilinear preferences it is shown how mirrlees optimal nonlinear income tax problem can be simplified to a reduced form problem involving only the allocation of the consumption good this result is a finite version of a proposition established in the continuum by s lollivier and j c rochet

intertemporal quality discrimination of a durable good monopolist abstract consider a durable good monopolist facing the technology constraint that when he introduces a new product he cannot produce a cheaper variant without a time lag we show that the qualities of his high end and low end products are higher than their efficient quality levels

group buying on the web a comparison of price discovery mechanisms web based group buying mechanisms are being widely used for both business to business b2b and business to consumer b2c transactions we survey currently operational online group buying markets and then study this phenomenon using analytical models we build on the literatures in information economics and operations management in our analytical model of a monopolist offering web based group buying under different kinds of demand uncertainty we derive the monopolist s optimal group buying schedule under varying conditions of heterogeneity in the demand regimes and compare its profits with those that obtain under the more conventional posted price mechanism we further study the impact ofproduction postponement by endogenizing the timing of the pricing and production decisions in a two stage game between the monopolist and buyers our results have implications for firms choice of price discovery mechanisms in e markets and for the scheduling of production and pricing decisions in the presence and absence of scale economies of production

nonlinear pricing and price cap regulation abstract this paper analyzes profit maximizing nonlinear pricing by a firm that is subject to price cap regulation two forms of regulatory constraint are considered i a cap on the firm s average revenue and ii a constraint that the firm must continue to offer each consumer the option of buying at the uniform price optimal nonlinear price schedules in these regimes are shown to have simple characterizations that are related to the nonlinear tariffs that an unregulated monopolist would charge of the regulatory regimes the firm prefers the average revenue constraint to the option constraint and likes uniform pricing least consumers in aggregate prefer the option regime to uniform pricing and like the average revenue constraint least but there are also distributional effects between consumers although the optional tariff regime pareto dominates uniform pricing it is ambiguous whether welfare is higher under uniform pricing or under the average revenue regime an example is used to illustrate the nature of the ambiguity

equivalence between the diamond dybvig banking model and the optimal income taxation model abstract it is shown that the diamond dybvig journal of political economy 96 1983 768 banking model with a continuum of types of agents has the same analytical structure as the standard optimal income taxation model review of economic studies 38 1971 175 review of economic studies 43 1976 261 insights from the income taxation literature immediately imply that a bank run equilibrium exists in the banking model as long as the long term project is sufficiently costly to liquidate

output fluctuations and fiscal policy u s state and local governments 1978 1994 abstract we study the cyclical properties of u s state and local government fiscal policy the budget surpluses of both are procyclical over short and medium term horizons procyclical surpluses are the result of strongly procyclical revenue and weakly procyclical expenditure these results hold whether aggregate u s wide fluctuations are controlled for or not federal grants to state and local governments are procyclical but this is due to aggregate output fluctuations with respect to state level output fluctuations federal grants are countercyclical the budget surpluses of trust funds and utilities are also procyclical but there is no evidence that this effect is stronger in states where balanced budget rules are tighter the cyclical patterns of state and local budget surpluses are affected by various political institutions for example budget surpluses are less procyclical in conservative states in an election year that occurs in good times state governments refrain from accumulating a larger surplus in bad times no such asymmetry between election and non election years is apparent

involuntary unemployment and worker self selection abstract consider a firm that lacks information about the reservation wage or ability of any specific worker but is aware that workers with higher reservation wages tend to be more able on average we show that under a simple condition that the efficiency wage exceeds the lowest reservation wage the optimal hiring policy for the firm involves 1 no wage discrimination and 2 rationing of jobs when demand for its product is low the result also extends to the case where hours of work are variable provided each worker is most productive when working a strictly positive number of hours per week

government spending cyclicality evidence from transitory and persistent shocks in developing countries we revisit the debate of whether government spending is procyclical in developing countries our main contribution is to argue that beyond exogeneity of the income shock an empirical analysis of government spending cyclicality must be carefully tailored to the shock s persistence we first illustrate this point in a simple intertemporal model we then use instrumental variables estimation to characterize the response of government expenditures to exogenous shocks with different degrees of persistence our estimation strategy exploits that i year to year variations in rainfall have a significant positive contemporaneous effect on sub saharan african countries real gdp but this effect is transitory ii year to year variations in the gdp of sub saharan african countries oecd trading partners have a significant positive contemporaneous effect on sub saharan african countries real gdp and this effect is persistent using rainfall as an instrument for sub saharan african countries gdp yields a government consumption expenditures elasticity response of around 0 4 standard error 0 3 when the instrument is the gdp of sub saharan african countries oecd trading partners the estimated government consumption expenditures elasticity response is around 1 1 standard error 0 2 the elasticity response of government consumption expenditures to persistent income shocks is thus significantly higher relative to transitory shocks

combining rent seeking and public choice theory in the analysis of tariffs versus quotas economists continuing criticisms of protectionism make a valuable contribution to the general interest element of the forces which operate to keep propensities to protect somewhat in check mckenzie rightly warns however that proposals by economists for giving protection in more efficient forms run the danger of increasing the total supply of protection thus we agree that serious consideration should be given to the political economy responses which may be induced before one advocates ways of doing more efficiently what one believes should not be done in the first place it does not follow however that all such policies will have net negative unanticipated consequences in the case of tariffs versus quotas we do not believe that we have yet sufficient knowledge of all of the relevant political economy considerations to predict about the full effects of legislation which allowed trade protection to only take the form of tariffs we are doubtful however that such a measure would increase the total quantity of protection through the channels outlined by mckenzie we believe that the same type of basic public choice analysis of the individual incentives to lobby which suggests that consumer taxpayers will not force the political process to operate so as to maximize aggregate economic efficiency with respect to the level of protection also suggests that the net lobbying for quotas is likely to be higher on average than the net lobbying for tariffs political effectiveness and ability to overcome free riding on the part of tariff revenue seekers is likely to be low at the margin furthermore issues of visibility and institutional structure are likely to lessen the ability of anti protection forces to lobby against quotas placed within a broader framework public choice and rent seeking theory is consistent with the empirical evidence that where quotas are used protection is high

regulating a monopolist with unknown costs we consider the problem of how to regulate a monopolistic firm whose costs are unknown to the regulator the regulator s objective is to maximize a linear social welfare function of the consumers surplus and the firm s profit in the optimal regulatory policy prices and subsidies are designed as functions of the firm s cost report so that expected social welfare is maximized subject to the constraints that the firm has nonnegative profit and has no incentive to misrepresent its costs we explicitly derive the optimal policy and analyze its properties in their classic papers dupuit 2 and hotelling 5 considered pricing policies for a bridge that had a fixed cost of construction and zero marginal cost they demonstrated that the pricing policy that maximizes consumer well being is to set price equal to marginal cost and to provide a subsidy to the supplier equal to the fixed cost so that a firm would be willing to provide the bridge this first best solution is based on a number of informational assumptions first the demand function is assumed to be known to both the regulator and to the firm while the assumption of complete information may be too strong the assumption that information about demand is as available to the regulator as it is to the firm does not seem unnatural a second informational assumption is that the regulator has complete information about the cost of the firm or at least has the same information about cost as does the firm this assumption is unlikely to be met in reality since the firm would be expected to have better information about costs than would the regulator as weitzman has stated an essential feature of the regulatory environment i am trying to describe is uncertainty about the exact specification of each firm s cost function in most cases even the managers and engineers most closely associated with production will be unable to precisely specify beforehand the cheapest way to generate various hypothetical output levels because they are yet removed from the production process the regulators are likely to be vaguer still about a firm s cost function 12 p 684 as this observation suggests it is natural to expect that a firm would have better information regarding its costs than would a regulator the purpose of this paper is to develop an optimal regulatory policy for the case in which the regulator does not know the costs of the firm one strategy that a regulator could use in the absence of full information about costs is to give the firm the title to the total social surplus and to delegate the pricing decision to the firm in pursuing its own interests which would then be to maximize the total social surplus the firm would adopt the same marginal cost pricing strategy that the regulator would have imposed if the regulator had
