a tale of tax policies in open economies recent financial crises in europe as well as the periodic battles in the u s over the debt ceiling point to the importance of fiscal discipline among developed countries this paper develops an open economy model calibrated to the u s and a subset of the emu to evaluate the impact of various permanent tax changes the first set of experiments considers a targeted one percentage point reduction in the government deficit to gdp ratio through raising one of the consumption tax the labor income tax or the capital income tax in terms of welfare the consumption tax is found to be the least costly of the tax increases a second set of experiments looks at deficit neutral tax changes partially replacing the capital income tax with either a higher labor income tax or higher consumption tax and partially replacing the labor income tax with an increased consumption tax reducing reliance on capital income taxation is welfare enhancing although it leads to short term losses reducing labor income taxation improves international competitiveness and is welfare improving

monetary policy under alternative asset market structures the case of a small open economy can the structure of asset markets change the way monetary policy should be conducted following a linear quadratic approach the present paper addresses this question in a new keynesian small open economy framework our results reveal that the configuration of asset markets significantly affects optimal monetary policy and the performance of standard policy rules in particular when comparing complete and incomplete markets the ranking of policy rules is entirely reversed and so are the policy prescriptions regarding the optimal level of exchange rate volatility

imperfect information and price rigidity the purpose of this paper is to present a microeconomic model of pricing behavior that is consistent with macroeconomic theory and evidence the essential ingredient in the model is the hypothesis that imperfect information implies that firms face kinked demand curves i provide a detailed analysis of this hypothesis and develop its empirical implications the model provides a microeconomic rationale for the price stickiness assumed in disequilibrium macroeconomic models

ramsey optimal tax reforms and real exchange rate dynamics abstract we solve the ramsey optimal tax plan for a small open economy with an endogenously determined real exchange rate the open economy constrains the government s setting of the capital income tax rate since physical capital cannot be dominated in rate of return by foreign assets however the endogenous real exchange rate loosens this constraint relative to a one good open economy model in which the real exchange rate is necessarily fixed we find that the dynamics of the two good small open economy model more closely resemble those of a closed economy model than a one good small open economy model

the theory of public goods non nash behaviour abstract most treatments of equilibrium public goods provision assume zero conjectural variations in the sense that each individual regards the behaviour of the rest of the community as independent of his own this paper introduces nonzero conjectural variations into the model a diagram is introduced which can depict both the individual s and the community s equilibrium in the presence of nonzero conjectural variations equilibrium and optimal outcomes are compared and a specific functional form is used to investigate the effect of community size on the nature of equilibrium finally we discuss the requirement that conjectures should be consistent

do central banks respond to exchange rate movements a structural investigation abstract we estimate a small scale structural general equilibrium model of a small open economy using bayesian methods our main focus is the conduct of monetary policy in australia canada new zealand and the uk we consider generic taylor type rules where the monetary authority reacts in response to output inflation and exchange rate movements we perform posterior odds tests to investigate the hypothesis whether central banks do target exchange rates the main result of this paper is that the central banks of australia and new zealand do not whereas the bank of canada and the bank of england do include the nominal exchange rate in its policy rule this result is robust for various specification of the policy rule we also find that terms of trade movements do not contribute significantly to domestic business cycles

monetary policy and exchange rate volatility in a small open economy we lay out a small open economy version of the calvo sticky price model and show how the equilibrium dynamics can be reduced to a simple representation in domestic inflation and the output gap we use the resulting framework to analyse the macroeconomic implications of three alternative rulebased policy regimes for the small open economy domestic inflation and cpi based taylor rules and an exchange rate peg we show that a key difference among these regimes lies in the relative amount of exchange rate volatility that they entail we also discuss a special case for which domestic inflation targeting constitutes the optimal policy and where a simple second order approximation to the utility of the representative consumer can be derived and used to evaluate the welfare losses associated with the suboptimal rules

on the international dimension of fiscal policy this paper analyses the international dimension of fiscal policy using a small open economy framework in which the government finances its spending by levying distortionary taxation and issuing non state contingent debt the main finding of the paper is that once the open economy aspect of the policy problem is considered it is not optimal to smooth taxes following idiosyncratic shocks even when prices are flexible and inflation can costlessly act as a shock absorber to restore fiscal equilibrium the presence of a terms of trade externality lead to movements in the tax rate also in contrast with the closed economy the introduction of sticky prices can reduce the optimal volatility of taxes

price stability in open economies this paper studies the conditions under which price stability is the optimal policy in a two country open economy model with imperfect competition and price stickiness special conditions on the levels of country specific distortionary taxation and the intratemporal and intertemporal elasticities of substitution need to be satisfied these restrictions apply to both cooperative and non cooperative settings most importantly we show that cooperative and non cooperative solutions do not coincide despite market completeness and producer currency pricing in this framework our analysis suggests a role for international policy coordination

sticky price models of the business cycle can the contract multiplier solve the persistence problem we construct a quantitative equilibrium model with firms setting prices in a staggered fashion and use it to ask whether monetary shocks can generate business cycle fluctuations these fluctuations include persistent movements in output along with the other defining features of business cycles like volatile investment and smooth consumption we assume that prices are exogenously sticky for a short time persistent output fluctuations require endogenous price stickiness in the sense that firms choose not to change prices much when they can do so we find that for a wide range of parameter values the amount of endogenous stickiness is small thus we find that in a standard quantitative model staggered price setting alone does not generate business cycle fluctuations

the role of consumption substitutability in the international transmission of monetary shocks abstract this paper develops a general framework to analyze the impact of monetary shocks in an open economy focusing on the role of the degree of substitutability between goods produced in different countries we extend the contributions by obstfeld and rogoff obstfeld m rogoff k 1995 exchange rate dynamics redux journal of political economy 103 624 659 and corsetti and pesenti corsetti g pesenti p 1997 welfare and macroeconomic interdependence nber working paper 6307 to show that the welfare impact differs across countries when the degree of substitutability between goods produced in different countries is different from the degree of substitutability between goods produced in the same country a shock that would be beneficial in a closed economy can have an adverse beggar thyself effect in the country where it takes place or an adverse beggar thy neighbor effect on its neighbor

redistributive taxation in a simple perfect foresight model abstract we investigate the redistributive potential of capital taxation in an intertemporal maximizing model of capital formation first even unanticipated redistributive capital taxation is severely limited in its effectiveness since it depresses wages second under any convergent redistributive tax policy which maximizes a paretian social objective the capital income tax will converge to zero independent of the factor supply elasticities these results are independent of workers holdings of capital

optimal taxation without state contingent debt in an economy studied by lucas and stokey tax rates inherit the serial correlation structure of government expenditures belying barro s earlier result that taxes should be a random walk for any stochastic process of government expenditures to recover a version of barro s random walk tax smoothing outcome we modify lucas and stokey s economy to permit only risk free debt having only risk free debt confronts the ramsey planner with additional constraints on equilibrium allocations beyond one imposed by lucas and stokey s assumption of complete markets the ramsey outcome blends features of barro s model with lucas and stokey s in our model the contemporaneous effects of exogenous government expenditures on the government deficit and taxes resemble those in lucas and stokey s model but incomplete markets put a near unit root component into government debt and taxes an outcome like barro s however we show that without ad hoc limits on the government s asset holdings outcomes can diverge in importa

the macroeconomic effects of lockdown policies abstract a tractable incomplete market model with endogenous unemployment risk sticky prices real wage rigidity and a fiscal side is calibrated to euro area countries and used to analyze the macroeconomic effects of lockdown policies modeling them as a shock to the extensive margin of labor adjustment a rise in separations produces large and persistent negative effects on output unemployment and welfare raises precautionary savings and lowers inflation in line with early evidence about inflation dynamics modeling lockdowns as a shock to the intensive margin a fall in labor utilization produces small and short lived macroeconomic and welfare effects and implies a counterfactual rise in inflation conditional on a lockdown separation shock raising public spending or extending ui benefits by large amounts is much more effective in stimulating the economy than during normal times quantitatively however the ability of such policies to flatten the output and unemployment curves remains limited even though these policies can alleviate a reasonable share of the aggregate welfare losses from the lockdown

global implications of self oriented national monetary rules author s obstfeld maurice rogoff kenneth abstract it is well known that if international linkages are relatively small the potential gains to international monetary policy coordination are typically quite limited but what if goods and financial markets are tightly linked is it then problematic if countries unilaterally design their institutions for monetary stabilization are the stabilization gains from having separate currencies largely squandered in the absence of effective international monetary coordination we argue that under plausible assumptions the answer is no unless risk aversion is very high lack of coordination in rule setting is a second order problem compared to the overall gains from monetary policy stabilization

equilibrium capital taxation in open economies under commitment abstract this paper analyzes equilibrium capital taxation in open economies with strategic interaction in a neo classical growth model under perfect commitment i show that non cooperative capital taxes are zero in the long run for a large open economy thereby generalizing the result previously established only for the special cases of a closed and a small open economy this does not represent a race to the bottom though since the result is independent of the degree of capital mobility the number of countries or a country s size relative to the rest of the world moreover when countries cooperate they still set capital taxes to zero in the long run these outcomes are robust to different equilibrium specifications the inclusion of endogenous government spending and heterogeneous agents and non linear labor income taxation governments find it optimal to implement the efficient capital allocation in the long run both in a closed and an open economy this trumps incentives to tax foreigners domestic capital holdings by raising capital taxes and attracting capital from abroad by lowering capital taxes

fiscal policy and inflation in a monetary union this paper studies optimal scal policies in a small open economy within a mon etary union the government has access to nominal non state contingent debt and distortionary labour taxes to nance exogenous spending price levels dier across countries due to consumption home bias thus scal policy in uences in ation and the terms of trade prices are exible we show that unlike in a country with an inde pendent monetary policy some variability in labour taxes is optimal this is true even when the terms of trade externality is shut down while scal policy aims at smooth ing production distortions with nominal public debt there is an incentive to use taxes to in ate in bad times when debt levels are high reminiscent of chari et al s 1991 optimal monetary policy result

dynamic optimal taxation in small open economies abstract this paper examines the effects of perfect capital mobility on the determination of optimal capital taxation it shows that capital movements do not change dramatically the optimal tax path studied for the closed economy in addition the paper provides a counterexample to the standard belief that the worldwide system is the optimal regime of taxation finally it shows that the rate of taxation of the rest of the world is not fundamental to determine the optimal decision of a small economy

an empirical investigation of customer market analysis a microfoundation for macroeconomics the slow adjustment and stickiness of output prices is widely regarded as an important determinant of macroeconomic behaviour recently a number of writers have argued that customer market analysis can provide a microfoundation for price stickiness this paper develops the theory of a firm selling in a customer market and investigates the empirical implications of the theory the model is shown to imply a particular pattern of behaviour between retail prices and wholesale prices data on retail and wholesale prices for the united states the united kingdom and australia at various levels of aggregation is investigated and found to support the predictions of the customer market model in the conclusion the macroeconomic implications of the empirical conslusions are drawn out

international business cycles with endogenous incomplete markets backus kehoe and kydland 1992 baxter and crucini 1995 and stockman and tesar 1995 find two major discrepancies between standard international business cycle models with complete markets and the data in the models cross country correlations are much higher for consumption than for output while in the data the opposite is true and cross country correlations of employment and investment are negative while in the data they are positive this paper introduces a friction into a standard model that helps resolve these anomalies the friction is that international loans are imperfectly enforceable any country can renege on its debts and suffer the consequences for future borrowing to solve for equilibrium in this economy with endogenous incomplete markets the methods of marcet and marimon 1999 are extended incorporating the friction helps resolve the anomalies more than does exogenously restricting the assets that can be traded

theory measurement and calibration of macroeconomic models abstract calibration has become a standard tool of macroeconomics this paper extends and refines the calibration methodology along several important dimensions first accounting for home production is important both in measuring calibration targets and in organizing the data in a model consistent fashion for this reason thinking about home production is important even if the model under consideration does not include home production second investment specific technological change is included because of its strong balanced growth parameter restrictions third the measurement strategy is laid out as transparently as possible so that others can easily replicate the underlying calculations the data and calculations used in this paper are available at http clevelandfed org research models rbc index cfm

optimal fiscal and monetary policy some recent results this paper studies the quantitative properties of fiscal and monetary policy in business cycle models in terms of fiscal policy optimal labor tax rates are virtually constant and optimal capital income tax rates are close to zero on average in terms of monetary policy the friedman rule is optimal nominal interest rates are zero and optimal monetary policy is activist in the sense that it responds to shocks to the economy

monetary policy and welfare in a small open economy this paper analyzes optimal monetary policy in a small open economy featuring monopolistic competition and nominal rigidities it shows that the utility based loss function for this economy can be written as a quadratic expression of domestic inflation output gap and real exchange rate the presence of an internal monopolistic distortion and a terms of trade externality drives optimal policy away from domestic inflation targeting and affects the optimal level of exchange rate volatility when domestic and foreign goods are close substitutes for each other the optimal policy rule implies lower real exchange rate volatility than a domestic inflation targeting regime the reverse is true when the elasticity of substitution between goods is low

inflation stabilization and welfare the case of a distorted steady state this paper considers the appropriate stabilization objectives for monetary policy in a microfounded model with staggered price setting rotemberg and woodford 1997 and woodford 2002 have shown that under certain conditions a local approximation to the expected utility of the representative household in a model of this kind is related inversely to the expected discounted value of a conventional quadratic loss function in which each period s loss is a weighted average of squared deviations of inflation and an output gap measure from their optimal values zero however those derivations rely on an assumption of the existence of an output or employment subsidy that offsets the distortion due to the market power of monopolistically competitive price setters so that the steady state under a zero inflation policy involves an efficient level of output here we show how to dispense with this unappealing assumption so that a valid linear quadratic approximation to the optimal policy problem is possible even when the steady state is distorted to an arbitrary extent allowing for tax distortions as well as market power and when as a consequence it is necessary to take account of the effects of stabilization policy on the average level of output we again obtain a welfare theoretic loss function that involves both inflation and an appropriately defined output gap though the degree of distortion of the steady state affects both the weights on the two stabilization objectives and the definition of the welfare relevant output gap in the light of these results we reconsider the conditions under which complete price stability is optimal and find that they are more restrictive in the case of a distorted steady state we also consider the conditions under which pure randomization of monetary policy can be welfare improving and find that this is possible in the case of a sufficiently distorted steady state though the parameter values required are probably not empirically realistic

fiscal and monetary rules for a currency union abstract this paper addresses the optimal joint conduct of fiscal and monetary policy in a two country model of a currency union with staggered price setting and distortionary taxes a tractable linear quadratic approximation permits a representation of the optimal policy plan in terms of targeting rules in the optimal equilibrium monetary policy should achieve aggregate price stability following a flexible inflation targeting rule fiscal policy should stabilize idiosyncratic shocks allowing for permanent variations of government debt but should abstain from creating inflationary expectations at the union level simple policy rules can approximate the optimal commitment benchmark through a mix of strict inflation targeting and flexible budget rules conversely the welfare costs of balanced budget rules are at least one order of magnitude higher than conventional estimates of the costs of business cycle fluctuactions

optimal fiscal and monetary policy in an economy without capital abstract this paper is concerned with the structure and time consistency of optimal fiscal and monetary policy in an economy without capital in a dynamic context optimal taxation means distributing tax distortions over time in a welfare maximizing way for a barter economy our main finding is that with debt commitments of sufficiently rich maturity structure an optimal policy if one exists is time consistent in a monetary economy the idea of optimal taxation must be broadened to include an inflation tax and we find that time consistency does not carry over an optimal inflation tax requires commitment by rules in a sense that has no counterpart in the dynamic theory of ordinary excise taxes the reason time consistency fails in a monetary economy is that nominal assets should from a welfare maximizing point of view always be taxed away via an immediate inflation in a kind of capital levy this emerges as a new possibility when money is introduced into an economy without capital

non cooperative bargaining theory an introduction the paper provides an informal introduction to some of the main themes of the recent literature on non cooperative or sequential bargaining models it focuses in particular on the relationship between the new approach and the traditional axiomatic approach exemplified by nash bargaining theory it illustrates the new insights offered by the non cooperative approach by reference to a detailed analysis of the manner in which the presence of an outside option available to one of the parties will affect the negotiated outcome finally the difficulties which arise in extending this analysis to two person bargaining with incomplete information and to n person bargaining are discussed this is a revised version of the fourth review of economic studies lecture presented in april 1985 at the joint meeting of the association of university teachers of economics and the royal economic society held in oxford the choice of lecturer is made by a panel whose members are currently professors hahn mirrlees and nobay and the paper is refereed in the usual way this paper aims to provide an informal and elementary introduction to an approach to bargaining which has received a great deal of attention over the past few years the approach involves writing down some particular sequence of moves offers and replies to be made over time in the course of negotiations and then looking for a non cooperative equilibrium in the game thus specified in practice a perfect equilibrium or in games of incomplete information a sequential equilibrium while the approach appears at first sight to be very different in spirit from the traditional axiomatic approach in which a bargaining solution is specified by appealing to a number of general requirements which are deemed appropriate on the basis of some a priori considerations the two approaches are in fact complementary while the

residence and source based capital taxation in open economies with infinitely lived consumers abstract in this paper we investigate tax competition in a neoclassical growth model where each country may use both residence and source based capital taxes we show that both types of capital taxes are zero at any interior steady state just as in a closed economy for symmetric countries and even for countries that differ only with respect to size and productivity we prove analytically and verify numerically that the open economy policies coincide exactly with the closed economy policies in all time periods for countries that are asymmetric in other dimensions we find that source based taxes are used to manipulate the intertemporal terms of trade in the short run either way the fiscal externalities of source based taxes vanish once residence based taxes are allowed

welfare and macroeconomic interdependence we develop a baseline model of monetary and fiscal transmission in interdependent economies the welfare effects of expansionary policies are related to monopolistic supply in production and monopoly power of a country in trade an unanticipated exchange rate depreciation can be beggar thyself rather than beggar thy neighbor as gains in domestic output are offset by deteriorating terms of trade smaller and more open economies are more prone to suffer from inflationary shocks larger economies benefit from moderate demand led expansions but may be worse off if policy makers attempt to close the output gap fiscal shocks are generally beggar thy neighbor in the long run in the short run they raise domestic demand at given terms of trade thus reducing the welfare benefits from monetary expansions analytical tractability makes our model uniquely suitable as a starting point to approach the recent new open economy macroeconomic literature

the cyclical nature of markups in canadian manufacturing a production theory approach in this paper the effects of cost and demand characteristics on the magnitude and cyclical behaviour of markups in canadian manufacturing are measured within a production theory framework price to marginal cost ratios for various manufacturing industries are computed and the impact art their secular and cyclical trends from changes in capacity utilization scale economies variable input prices import competition unemployment and other exogenous market and technological determinants are explored using adjusted markup indexes and elasticities the measured price margins seem weakly procyclical further evaluation of the determinants of these cycles suggests that the procyclical nature of markups is primarily related to exogenous factors affecting costs such as energy price shocks and that cost characteristics underlying scale economies provide a countercyclical influence that counteracts the profitability arising from markups

optimal fiscal and monetary policy equivalence results in this article we analyze the implications of price setting restrictions for the conduct of cyclical fiscal and monetary policy we consider standard monetary economies that differ in the price setting restrictions imposed on the firms we show that independently of the degree or type of price stickiness it is possible to implement the same efficient set of allocations and that each allocation in that set is implemented with policies that are also independent of the price stickiness in this sense environments with different price setting restrictions are equivalent

designing targeting rules for international monetary policy cooperation this study analyzes a two country dynamic general equilibrium model with nominal rigidities monopolistic competition and producer currency pricing a quadratic approximation to the utility of the consumers is derived and assumed as the policy objective function of the policymakers it is shown that only under special conditions there are no gains from cooperation and moreover that the paths of the exchange rate and prices in the constrained efficient solution depend on the kind of disturbance that affects the economy it might be the case either for fixed or floating exchange rates despite this result simple targeting rules that involve only targets for the growth of output and for both domestic gdp and cpi inflation rates can replicate the cooperative allocation

optimal simple and implementable monetary and fiscal rules welfare maximizing monetary and fiscal policy rules are studied in a model with sticky prices money and distortionary taxation the ramsey optimal policy is used as a point of comparison the main findings are the size of the inflation coefficient in the interest rate rule plays a minor role for welfare it matters only insofar as it affects the determinacy of equilibrium optimal monetary policy features a muted response to output interest rate rules that feature a positive response to output can lead to significant welfare losses the welfare gains from interest rate smoothing are negligible optimal fiscal policy is passive the optimal monetary and fiscal rule combination attains virtually the same level of welfare as the ramsey optimal policy

ramsey policies in a small open economy with sticky prices and capital this paper analyzes jointly optimal fiscal and monetary policies in a small open economy with capital and sticky prices we allow for trade in consumption goods under perfect international risk sharing we consider balanced budget fiscal policies where authorities use distortionary taxes on labor and capital together with monetary policy using the nominal interest rate first as long as a symmetric equilibrium is considered the steady state in an open economy is isomorphic to that of a closed economy second whereas sticky prices allocations are almost indistinguishable from flexible prices allocations the open economydimension delivers results that are qualitatively similar to those of a closed economy but with significant quantitative changes fluctuations in terms of trade implied by complete international financial markets affect i consumption through changes in the consumption price index cpi ii hours through changes in the cpi based real wage and iii capital accumulation through the relative price of capital goods these wedges affect the volatility and persistence of optimal tax rates and resulting allocations are quite different as compared to a closed economy

multimarket market power estimation the australian retail meat sector a new technique for estimating market power in several markets simultaneously is developed and applied to the australian retail beef lamb and pork markets the hypotheses that market power is zero and that market power is the same for each meat cannot be rejected nor is there evidence that market power increased over the period of analysis little bias is created by examining markets is isolation rather than within a system when markets are competitive but that bias can be large when market power exists in some markets in the system

efficient investment incentives in the presence of capital flight abstract this paper examines the efficiency of quantity restrictions on capital exports and the accompanying set of taxes when a government can effectively tax foreign source income then it is not efficient to impose restrictions on capital exports and the optimal tax rates on foreign source and domestic source income are the same an efficient allocation of domestic savings between foreign and domestic investment is obtained however when the government cannot tax foreign source income it is optimal to impose such a restriction so as to induce overinvestment in domestic capital

sustainable international monetary policy cooperation abstract we provide new insight on international monetary policy cooperation in a familiar two country setting a country facing a relatively more volatile markup shock has an incentive to deviate from an assumed cooperation regime to a non cooperation regime a similar result obtains if countries differ in size have non unitary elasticity of substitution between domestic and foreign goods and have different degrees of trade openness home bias in consumption this motivates our study of an endogenous history dependent sustainable cooperation regime its history contingent welfare redistributions are supported by incentive compatible variations in resource transfers through the terms of trade or net exports such an endogenous cooperative solution may also provide a theoretical rationale for perceived occasional cooperation between national central banks in reality

customer markets trade unions and stagflation customer market analysis combined with trade union wage setting is shown to yield a range of equilibrium levels of employment only when employment is forced outside this range can the disequilibrium acceleration or d eceleration of the price level be expected to operate numerical calc ulations suggest that this range is quite large implying that the ma ximum level of unemployment consistent with nondecelerating inflation is way above the minimum level of unemployment consistent with nonac celerating inflation a range of equilibrium employment levels appear s to be in closer agreement with empirical experience than a unique natural rate of unemployment copyright 1987 by the review of economic studies limited

on the relevance of exchange rate regimes for stabilization policy this paper assesses the relevance of the exchange rate regime for stabilization policy using both fiscal and monetary policy we conclude that the exchange rate regime is irrelevant this is the case independently of the severity of price rigidities independently of asymmetries across countries in shocks and transmission mechanisms the only relevant conditions are on the mobility of labor and financial assets the results can be summarized with the claim that every currency area is an optimal currency area however with labor mobility or tradable state contingent assets additional policy instruments would be required to establish the irrelevance result

inflation targeting should it be modeled as an instrument rule or a targeting rule abstract the paper discusses how current inflation targeting should be modeled and argues that it is better represented as a commitment to a targeting rule a rule specifying operational objectives for monetary policy or a condition for the target variables than as a commitment to a simple instrument rule like a taylor rule

monetary and fiscal policy interactions in a micro founded model of a monetary union abstract this paper analyzes in detail the mechanisms behind fiscal stabilization policy and the role of policy commitment in a micro founded new keynesian model of a two country monetary union which is hit by supply shocks we also explore the determinants of the gains from fiscal stabilization while monetary policy with identical union members is concerned with stabilizing the union wide economy fiscal policy aims at stabilizing inflation differences and the terms of trade besides exploring optimal policies we also consider monetary and fiscal rules we study these rules both under coordination and non coordination by the fiscal authorities

optimal monetary and fiscal policy in a currency union we lay out a tractable model for the analysis of optimal monetary and fiscal policy in a currency union the monetary authority sets a common interest rate for the union whereas fiscal policy is implemented at the country level through the choice of government spending in the presence of country specific shocks and nominal rigidities the policy mix that is optimal from the viewpoint of the union as a whole requires that inflation be stabilized at the union level by the common central bank whereas fiscal policy has a country specific stabilization role one beyond the efficient provision of public goods

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

incomplete pass through and the welfare effects of exchange rate variability abstract this paper considers the implications of incomplete exchange rate pass through for optimal monetary and exchange rate policy a two country model is presented which allows an explicit derivation of welfare functions in terms of a weighted sum of the second moments of producer prices and the nominal exchange rate from a single country perspective the optimal exchange rate variance depends on the degree of pass through the size and openness of the economy the elasticity of labour supply and the volatility of foreign producer prices welfare may be decreasing or increasing in the volatility of the exchange rate

international dimensions of optimal monetary policy abstract this paper provides a baseline general equilibrium model of optimal monetary policy among interdependent economies with monopolistic firms and nominal rigidities an inward looking policy of domestic price stabilization is not optimal when firms markups are exposed to currency fluctuations such a policy raises exchange rate volatility leading foreign exporters to charge higher prices vis a vis increased uncertainty in the export market as higher import prices reduce the purchasing power of domestic consumers optimal monetary rules trade off a larger domestic output gap against lower consumer prices optimal rules in a world nash equilibrium lead to less exchange rate volatility relative to both inward looking rules and discretionary policies even when the latter do not suffer from any inflationary or deflationary bias gains from international monetary cooperation are related in a non monotonic way to the degree of exchange rate pass through

on the efficiency and equity trade off abstract the concept of policy measures that create a potential pareto improvement has dominated normative economics the use of this concept in welfare economics relies on the availability of discriminatory lump sum transfers in such a way that the implementation of the efficient policy measure leads to a pareto movement in the economy however most studies of efficient policies preclude by assumption the existence of lump sum taxation this paper proposes in economies amenable to gorman aggregation one simple methodology to rank alternative allocations in terms of their distributional implications in a world with no lump sum transfers this methodology is simple because it is independent of the distribution of characteristics in the economy then for a specific policy measure it can be easily identified whether it implies an equity efficiency trade off the method is illustrated by analyzing the effects on inequality of the elimination of capital taxation the reduction of the inflation tax and the liberalization of capital movements in a small open economy

a theory of competition among pressure groups for political influence this paper presents a theory of competition among pressure groups for political influence political equilibrium depends on the efficiency of each group in producing pressure the effect of additional pressure on their influence the number of persons in different groups and the deadweight cost of taxes and subsidies an increase in deadweight costs discourages pressure by subsidized groups and encourages pressure by taxpayers this analysis unifies the view that governments correct market failures with the view that they favor the politically powerful both are produced by the competition for political favors

should capital income be taxed in the steady state this paper provides a new economic interpretation of the well known dynamic optimal taxation principle that capital income should not be taxed in the steady state we show that the result is related to the minimization of distortions at the intratemporal margin when every factor of production can be taxed at the optimal rate capital income should not be taxed in the steady state but when there are restrictions on the taxation of production factors the tax rate on capital income in the steady state is different from zero

optimal taxation of capital income in general equilibrium with infinite lives this paper analyzes the optimal tax on capital income in general equilibrium models of the second best agents have infinite lives and utility functions which are extensions from the koopmans form the population is heterogeneous the important property of the models is the equality between the social and the private discount rates in the long run i find that the optimal tax rate is zero in the long run for a special case of additively separable utility functions i then determine the tax rates along the dynamic path and conditions that are sufficient for the local stability of the steady state

what is wrong with taylor rules using judgment in monetary policy through targeting rules it is argued that inflation targeting is best understood as a commitment to a targeting rule rather than an instrument rule e ither ageneral targeting rule explicit objectives for monetary policy or a specific targeting rule a criterion for the forecasts of the target variables to be fulfilled essentially the equality of the marginal rates of transformation and substitution between the target variables targeting rules allow the use of judgment and extramodel information are more robust and easier to verify than optimal instrument rules and they can nevertheless bring the economy close to the socially optimal equilibrium

optimal fiscal and monetary policy under sticky prices this paper studies optimal fiscal and monetary policy under sticky product prices the theoretical framework is a stochastic production economy without capital the government finances an exogenous stream of purchases by levying distortionary income taxes printing money and issuing one period nominally risk free bonds the main findings of the paper are first for a miniscule degree of price stickiness i e many times below available empirical estimates the optimal volatility of inflation is near zero this result stands in stark contrast with the high volatility of inflation implied by the ramsey allocation when prices are flexible the finding is in line with a recent body of work on optimal monetary policy under nominal rigidities that ignores the role of optimal fiscal policy second even small deviations from full price flexibility induce near random walk behavior in government debt and tax rates third sluggish price adjustment raises the average nominal interest rate above the one called for by the friedman rule finally an interest rate feedback rule whereby the nominal interest rate depends on inflation and output fits well the data emanating from the ramsey economy however the fitted rule is not of the taylor type for the implied inflation coefficient is less than one and close to zero and the output coefficient is negative jel classification e52 e61 e63

factor income taxation and growth with increasing integration of world capital markets abstract in a closed economy the infinite horizon and the overlapping generations og model prescribe diametrically opposite policies on factor taxation the former argues that the growth maximizing capital income tax rate should be set to zero whereas the latter argues that it should be set as high as possible this note investigates the issue by taking into account global capital market integration we show that the long run growth maximizing capital income tax rate in a small open og economy is decreasing as the economy s capital market is increasingly integrated with the rest of the world and will be equal to zero as prescribed in the infinite horizon model once the degree of integration becomes sufficiently high

optimal fiscal policy with redistribution i study the optimal taxation oflabor and capital in a dynamic economy subject to government expenditure and technology shocks unlike representative agent ramsey models workers are heterogenous and lump sum taxation is not ruled out i consider two tax scenarios a linear taxation with a lump sum intercept and b nonlinear mirrleesian taxation when taxes are linear i derive a partial equivalence result with ramsey settings that provides a reinterpretation of such analyses i find conditions for perfect tax smoothing oflabor income taxes and zero capital taxation implications that contrast with ramsey are derived for public debt management for the nature of the time inconsistency problem and for the viability of replicating complete markets without state contingent bonds shifts in the distribution of skills provide a novel source for variations in tax rates for the nonlinear tax scenario i show that taxation based on income averages is optimal

financing of public goods and noncooperative theory of bargaining abstract this paper deals with an application of the noncooperative theory of bargaining to the financing of public goods we characterize the equilibrium of the bargaining game and perform comparative statics with respect to the model parameters in particular our results indicate that i if agreement from both parties is necessary to provide a public good the poorer party may make a negative contribution to the provision of a public good and ii if each party is free to provide the public good without the assent of the other party outside option principle then only non negative contributions are possible

taxation of investment and savings in a world economy the equilibrium of capital and equilibrium market prices are derived for a world economy with a unified securities market mobile capital no uncertainty and varying tax rates on different sources of income in each country the paper then characterizes optimal tax rates for a small country in this setting focusing on the peculiar incentives created when the before tax rate of return differs among securities due to differences in their typical tax treatment copyright 1986 by american economic association

optimal fiscal and monetary policy with sticky prices in this paper i consider the role of state contingent inflation as a fiscal shock absorber in an economy with nominal rigidities i study the ramsey equilibrium in a monetary model with distortionary taxation nominal non state contingent debt and sticky prices with sticky prices the ramsey planner must balance the shock absorbing benefits of state contingent inflation against the associated resource misallocation costs for government spending processes resembling post war experience introducing sticky prices generates striking departures in optimal policy from the case with flexible prices for even small degrees of price rigidity optimal policy displays very little volatility in inflation tax rates display greater volatility compared to the model with flexible prices with sticky prices tax rates and real government debt exhibit behavior similar to a random walk for government spending processes resembling periods of intermittent war and peace optimal policy displays extreme inflation volatility even when the degree of price rigidity is large as the variability in government spending increases smoothing tax distortions across states of nature becomes increasingly important and the shock absorber role of inflation is accentuated

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

productivity shocks stabilization policies and the dynamics of net foreign assets in this paper we investigate the role of macroeconomic stabilization policies for the international transmission of productivity shocks and their eects on the external sector we develop a two country stochastic dynamic new keynesian perpetual youth model of the business cycle with incomplete international nancial markets our olg structure implies stationary net foreign asset dynamics and allows for a thorough analysis of the interaction of monetary policy with non balanced budget scal policy we derive the dynamic and cyclical properties of scal decit feedback rules and their implications for net foreign assets dynamics our results imply that the degree of scal discipline i e the extent to which the scal rule responds to debt dynamics is crucial for the dynamics of net foreign assets we show that under a counter cyclical scal rule with low
