do side payments help collective decisions and strategic delegation i investigate when side payments facilitate cooperation in a context with strategic delegation on the one hand allowing side payments may be necessary when one party s participation con straint otherwise would be violated on the other with side payments each principal appoints a delegate that values the project less because this increases her bargaining power reluctant agents in turn implement too few projects i show that side payments are bad if the hetero geneity is small while the uncertainty and the typical value of the project are large with a larger number of parties there may be a stalemate without side payments but delegation becomes more strategic as well and cooperation decreases in either case jel c78 d78 f53 h77

bargaining over reform abstract this paper models the delay in a macroeconomic stabilization as the outcome of a bargaining game between two parties who must reach an agreement over how the stabilization cost is to be shared the paper modifies alesina and drazen s 1991 american economic review 81 1170 1189 war of attrition model by endogenizing the distribution of the stabilization costs through a bargaining game using this bargaining framework the paper analyzes the role of crises and foreign assistance in bringing about a settlement to the distributional conflict in the bargaining game a crisis that increases the welfare loss from not stabilizing the economy will lower the probability of delay in contrast foreign aid that is used to reduce the stabilization costs will further increase the delay in reaching an agreement between the two parties

centralized versus decentralized provision of local public goods a political economy approach abstract this paper takes a fresh look at the trade off between centralized and decentralized provision of local public goods it argues that the sharing of the costs of local public spending in a centralized system will create a conflict of interest between citizens in different jurisdictions when spending decisions are made by a legislature of locally elected representatives this conflict of interest will play out in the legislature depending on precisely how the legislature behaves the result may be excessive public spending or allocations of public goods characterized by uncertainty and misallocation across districts the extent of the conflict of interest between districts is affected by spillovers and differences in tastes for public spending thus the relative performance of centralized and decentralized systems depends upon spillovers and differences in tastes for public spending but for different reasons than suggested in the existing literature

is the united states really underinvesting in agricultural research comment the tax system may bias upward estimates of the rate of return to public agricultural research fox gives an example to illustrate the effect of failure to acknowledge the deadweight loss dwl of taxation by assuming a uniform stream of benefits the purpose of this note is a to show that fox s example overestimates the effect of dwl on the rate of return and b to use a more realistic stream of benefits to assess the effect of dwl

is the united states really underinvesting in agricultural research that the level of public investment in u s agricultural research is too low is widely accepted this paper argues that there are two important limitations to the evidence assembled in support of the underinvestment hypothesis a many authors have compared the social rate of return to public investments with the private rate of return to private investments b costs of public expenditures on agricultural research have been underestimated by a failure to account for the marginal excess burden of the tax collection system taking these two factors into account evidence in support of the underinvestment hypothesis is weakened considerably

rules transparency and political accountability rules of allocation and redistribution in the public sector are often less contingent on available information than normative theory would suggest this paper offers a political economy explanation under different rules even if the observable outcomes of policies remain the same the informational content which can be extracted by these observations is different less contingent rules allow citizens to gain more information on politicians and this improved information may be used to better select politicians this advantage may overcome the efficiency loss induced by flatter rules 2001 elsevier science b v all rights reserved

communication in federal politics universalism policy uniformity and the optimal allocation of fiscal authority the paper presents a positive model of policy formation in federal legislatures when delegates engage in the strategic exchange of policy relevant information depending on the type of policy under consideration communication between delegates generally suffers from a bias that makes truthful communication difficult and sometimes impossible this generates inefficient federal policy choices that are often endogenously characterized by overspending universalism and uniformity building on these findings i develop a theory of fiscal de centralization which revisits the work of oates in a world of incomplete information and strategic communication empirical results from a cross section of us municipalities are consistent with the predicted pattern of spending

optimal regional redistribution under asymmetric information this paper studies optimal redistribution among two different regions in a federal state regional governments supply local public goods financed with distorting local taxes they have better information on their tax bases than the federal government we model this both as an adverse selection problem on the size of local tax bases and or as moral hazard problem on local tax enforcement moral hazard alone does not affect the first best redistribution rule which is a lump sum transfer from the rich to the poor region in all other cases the optimal transfer rule involves a lump sum tax on the rich regions and a premium for fiscal effort by the poor regions with the transfer falling short of the first best level in the equilibrium with moral hazard and adverse selection tax evasion occurs only in the poor region even though the possibility of lax tax enforcement benefits the rich and harms the poor region because it reduces equilibrium redistribution this abstract was borrowed from another version of this item

decentralization duplication and delay we argue that although decentralization has advantages in finding low cost solutions these advantages are accompanied by coordination problems which lead to delay or duplication of effort or both consequently decentralization is desirable when there is little urgency or a great deal of private information but it is strictly undesirable in urgent problems when private information is less important we also examine the effect of large numbers and find that coordination problems disappear in the limit if distributions are common knowledge

multi issue bargaining with endogenous agenda abstract the first part of this paper shows that in a noncooperative bargaining model with alternating offers and time preferences the timing of issues the agenda matters even if players become arbitrarily patient this result raises the question of which agenda should come up endogenously when agents bargain over a set of unrelated issues it is found that simultaneous bargaining over packages should be a prevailing phenomenon but we also point to the possibility of multiple equilibria involving even considerable delay journal of economic literature classification number c78

cross border externalities and cooperation among representative democracies abstract this paper analyzes the provision of public goods with cross border externalities by representative democracies the level of provision of each country is decided by a policy maker elected by majority rule at the country level we compare the case in which policy makers set their policies noncooperatively with the case in which they set their policies through coasian cooperation cooperation induces policy makers to internalize cross border externalities but it also induces strategic voters to elect a policy maker who cares less about the public good to reduce their public good contribution the former effect increases public good provision while the latter reduces it we show that once voters incentives are taken into account whether cooperation is beneficial depends neither on voters preferences nor on the magnitude of spillovers nor on the size bargaining power or efficiency of each country instead it depends only on the curvature of the demand for the public good cooperation increases decreases public good provision when the demand function is more less convex than the unit elastic demand function hence the desirability of international cooperation depends mostly on the type of public good considered

strategic delay in bargaining with two sided uncertainty the role of strategic delay is analyzed in an infinite horizon alternating offer model of bargaining a buyer and seller are engaged in the trade of a single object both bargainers have private information about their own preferences and are impatient in that delaying agreement is costly an equilibrium is constructed in which the bargainers signal the strength of their bargaining positions by delaying prior to making an offer a bargainer expecting large gains from trade is more impatient than one expecting small gains and hence makes concessions earlier on trade occurs whever gains from trade exist but due to the private information only after costly delay panmunjom korea upi the american general and the north korean general glared at each other across the table and the only sound was the wind howling across the barren hills outside their hut maj gen james b knapp negotiator for the united nations command unc was waiting for maj gen ri choonsun of the democratic people s republic of north korea to propose a recess they sat there arms folded for 42 hours not a word finally gen ri got up walked out and drove away evening bulletin philadelphia 11 april 1969

why are stabilizations delayed when a stabilization has significant distributional implications e g tax increases to eliminate a large budget deficit socioeconomic groups may attempt to shift the burden of stabilization onto other groups the process leading to stabilization becomes a war of attrition each group attempting to wait the others out and stabilization occurring only when one group concedes and bears a disproportionate share of the burden the authors solve for the expected time of stabilization in a model of rational delay and relate it to several political and economic variables they motivate this approach and its results by comparison to historical and current episodes copyright 1991 by american economic association

the breakup of nations a political economy analysis this paper develops a model of the breakup or unification of nations in each nation the decision to separate is taken by majority voting a basic trade off between the efficiency gains of unification and the costs in terms of loss of control on political decisions is highlighted the model emphasizes political conflicts over redistribution policies the main results of the paper are i when income distributions vary across regions and the efficiency gains from unification are small separation occurs in equilibrium and ii when all factors of production are perfectly mobile all incentives for separation disappear i introduction following the demise of communism the entire map of europe from the atlantic coast to the urals is being redrawn and issues of separation unification and the redrawing of borders are yet again at the forefront of european concerns many of the issues raised by this process are primarily of a political cultural or linguistic nature however there are also economic considerations that bear on this problem the objective of this paper is to analyze some important economic and political determinants of the process of unification and separation of democratic nations the starting point of our analysis is to suppose that from an economic efficiency point of view separation of nations is never desirable a unified nation is always more efficient since free trade among regions is guaranteed duplication costs in defense and law enforcement are avoided and local public goods provision such as transportation and communication networks or common standards can be coordinated furthermore any benefits of decentralization that might be obtained in a world with several nations may also be achieved within a unified nation by replicating the administrative structure of the world with several

the benefit of crises for economic reforms when expenditures consistently outrun revenue the resulting inflation may have the effect of convincing the public and government that taxes must be raised to finance public investment in the advanced industrial countries income taxation and big spurts in taxation generally have become possible only under the impact of major emergency and crisis mostly in wartime in a number of developing countries in

reforming an asymmetric union on the virtues of dual tier capital taxation the tax competition for mobile capital in particular the reluctance of small countries to agree on measures of tax coordination has ongoing political and economic fallouts within europe we analyse the effects of introducing a two tier structure of capital taxation where the asymmetric member states of a union choose a common federal tax rate in the first stage and then non cooperatively set local tax rates in the second stage we show that this mechanism effectively reduces competition for mobile capital between the members of the union moreover it distributes the gains across the heterogeneous states in a way that yields a strict pareto improvement over a one tier system of purely local tax choices we also discuss the effects of diverging capital endowments within the union and capital flows to third countries

coordination in heterogeneous federal systems abstract we compare centralized and decentralized policy making in a federation in which policy heterogeneity is inherently costly and preferences vary across jurisdictions all jurisdictions agree that some harmonization is desirable but no one agrees on the direction of harmonization this type of collective choice problem arises when members of a federal system have to coordinate nonbudgetary policies such as laws regulations standards or diplomatic policies contrary to the common wisdom decentralization becomes optimal when coordination becomes very important when coordination costs are symmetric decentralization dominates centralization irrespective of the magnitude of externalities and the heterogeneity of preferences in the case of discontinuous network effects standardization never pareto dominates decentralization

experimentation in federal systems will decentralization lead to a laboratory in policy experimentation or is centralization necessary to prevent free riding in the innovation process we present a model where experiments have two dimensions all prefer quality but preferences

flexible integration mandatory and minimum participation rules should a subset of the eu members be allowed to form inner clubs and enhance cooperation or should integration proceed at the same speed for all while flexible cooperation allows members to participate if and only if they benefit it also generates a free rider problem if potential members choose to opt out the analysis shows that flexible cooperation is better only if the heterogeneity is large and the externality small but rigid cooperation will be the political equilibrium too often flexibility and rigidity can be combined by i mandatory participation rules where participation is voluntary unless a super majority requires everyone to participate and ii minimum participation rules where inner clubs must be sufficiently large the combination of mandatory and minimum participation rules may implement the best possible mechanism

federal mandates by popular demand this paper proposes a new framework for studying federal mandates regarding public policies in areas such as environmental quality public health highway safety and the provision of local public goods voters have single peaked preferences along a single policy dimension there are two levels of government federal and local the federal level can constrain local policy by mandating a minimum or maximum policy localities are free to adopt any policy satisfying the constraint imposed by the federal mandate we show that voters choose federal mandates that are too strict which leads to excessively severe mandates we show that similar results can obtain when federal provision of the public provided good is more efficient than local provision

decentralization externalities and efficiency in the competitive model externalities lead to inefficiencies and inefficiencies increase with the size of externalities however as argued by coase these problems may be mitigated in a decentralized system through voluntary coordination we show how coordination is limited by the combination of two factors respect for individual autonomy and the existence of private information together they imply that efficient outcomes can only be achieved through coordination when external effects are relatively large moreover there are instances in which coordination cannot yield any improvement at all despite common knowledge that social gains from agreement exist this occurs when external effects are relatively small and this may help to explain why coordination is so seldom observed in practice when improvements are possible we describe how simple subsidies can be used to implement second best solutions and explain why standard solutions such as pigovian taxes cannot be used possible extensions to issues arising in the structure of research joint ventures assumptions in the endogenous growth literature and the location of environmental hazards are also described

externalities vs internalities a model of political integration abstract decentralized government leads to inter regional externalities whereas an integrated jurisdiction solves the externality problem centralized government entails other costs in particular a neglect for minority interests the paper models formally the trade off between these two forces in determining the optimum as well as the equilibrium design of jurisdictions both the relative size of regions and the distribution of tastes are shown to be important parameters of the problem

international cooperation for sale abstract this paper shows that strong asymmetry among countries warrants a change in the rules of the game of global public goods provision with the consequence that cooperation by some countries is bought by others and aggregate welfare is increased perhaps substantially side payments on their own have virtually no effect on the outcomes that can be sustained by self enforcing cooperative agreements but when the rules of the game are changed by strong asymmetry when some countries are effectively committed to being non signatories to an agreement eschewing money transfers side payments become the vehicle for increasing participation in a cooperative agreement

on the timing of climate agreements a central issue in climate policy is the question whether long term targets for greenhouse gas emissions should be adopted this paper analyzes strategic effects related to the timing of such commitments using a two country model we identify a redistributive effect that undermines long term cooperation when countries are asymmetric and side payments are unavailable the effect enables countries to shift rents strategically via their r d efforts under delayed cooperation in contrast a complementarity effect stabilizes long term cooperation because early commitments in abatement induce countries to invest more in low carbon technologies and create additional knowledge spillovers contrasting both effects we endogenize the timing of climate agreements

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

international and institutional r d spillovers attribution of benefits among sources for brazil s new crop varieties reported rates of return to agricultural r d are generally high but they are likely to be biased particularly because of attribution problems mismatching research benefits with costs the importance of attribution biases is illustrated here with new evidence for brazil during 1981 2003 varietal improvements in upland rice edible beans and soybeans yielded benefits of 14 8 billion in present value 1999 prices terms attributing all of the benefits to embrapa a public research corporation accounting for more than half of brazil s agricultural r d spending the benefit cost ratio would be 78 1 under alternative attribution rules the ratio drops to 16 1

trade disputes and settlement we develop a model of trade agreements with renegotiation and imperfectly verifiable information in equilibrium trade disputes can occur and can be resolved in a variety of ways governments may settle early or trigger a court ruling and in the latter case they may implement the ruling or reach a post ruling settlement the model yields predictions on how the dispute outcome depends on the contracting environment and how it correlates with the optimal contract form we find support for a key prediction of our model using data on the outcomes of actual trade disputes in the general agreement on tariffs and trade world trade organization

resistance redistribution and investor friendliness abstract poor communities sometimes resist private investment and destroy economic surplus even if the government has the willingness and ability to redistribute we interpret such acts of resistance as demands for redistribution destruction contains credible information about how the affected group values surplus and such information is used by the government in implementing the optimal redistribution policy the extent of destruction is increasing in the extent of political marginalization of the affected group resistance not only destroys economic surplus it also mutes the investor s incentives to create surplus the government uses a tax subsidy on the investor to maximize weighted social surplus and we show that the possibility of destruction may force the government to be too soft in its negotiations with the investor we discuss several policy instruments that have the potential to improve welfare these include compensation floor for the affected group legal or financial protection for the investor and licensing fees for the investor

harmonization and side payments in political cooperation for two districts or countries that try to internalize externalities i analyze a bargaining game under private information i derive conditions for when it is efficient with uniform policies across regions with and without side payments and when it is efficient to prohibit side payments in the negotiations while policy differentiation and side payments allow the policy to better reflect local conditions they create conflicts between the regions and thus delay the results also describe when political centralization outperforms decentralized cooperation and they provide a theoretical foundation for the controversial uniformity assumption traditionally used by the fiscal federalism literature

the impact of sales taxation on internet commerce an empirical analysis abstract this paper examines how sales taxation on internet purchases could affect the decision to buy goods over the internet the results appear robust with respect to unobserved technological sophistication or other alternative explanations the tax effect is found to be significant and its magnitude suggests that applying a provincial average sales tax of 14 to all internet sales in canada would reduce the number of online buyers by as much as 44

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

north south negotiations on emission reductions a bargaining approach this article models north south negotiations on emission reductions where the north provides side payments in exchange for the south s adoption of a more stringent emission standard we find that depending on where firms compete strong asymmetry among regions the two regions different valuations of side payments and climate change damage can produce self enforcing cooperative agreements moreover the south s optimal standard choice can be one of two polar cases i e either the cleanest or the dirtiest irrespective of the continuum of standards available the results above can also hold true when both parties bargain over the south s emission tax

endogenous games and mechanisms side payments among players we characterize the outcomes of games when players may make binding offers of strategy contingent side payments before the game is played this does not always lead to efficient outcomes despite complete information and costless contracting the characterizations are illustrated in a series of examples including voluntary contribution public good games cournot and bertrand oligopoly principal agent problems and commons games among others

distributive politics and the costs of centralization this paper studies the choice between centralization and decentralization of fiscal policy in a political economy setting with centralization regional delegates vote over agendas comprising sets of region specific projects the outcome is inefficient because the choice of projects is insufficiently sensitive to within region benefits the number of projects funded may be non monotonic in the strength of project externalities the efficiency gains from decentralization and the performance of constitutional rules such as majority voting which may be used to choose between decentralization and centralization are then discussed in this framework weaker externalities and more heterogeneity between regions need not increase the efficiency gain from decentralization

interregional redistribution and mobility in federations a positive approach the paper studies the effects and the determinants of interregional redistribution in a model of residential and political choice we find that paradoxical consequences of inter jurisdictional transfers arise if people are mobile while self sufficient regions are nec essarily identical with respect to policies and average incomes in our model interregional redistribution always leads to the divergence of regional policies and per capita incomes thus interregional redistribution prevents interregional equality at the same time however transfers may allow for more interpersonal equality among the inhabitants of each region the voting population may therefore in a decision over the fiscal constitution deliberately implement such a transfer scheme to foster regional divergence empirical evidence from panel data from oecd countries and candian provinces is consistent with the theory

strategic delay in bargaining this paper analyses a bargaining model with incomplete information in which the time between offers is an endogenous strategic variable we find equilibria involving a delay to agreement that is due to the use of strategic time delay by bargainers to signal their relative strength under some specifications of the parameters delay is present in the unique sequential equilibrium whose beliefs satisfy one intuitive restriction this delay does not vanish as the minimal time between offers becomes small
