how important is fiscal policy cooperation in a currency union abstract by constructing a dynamic stochastic general equilibrium model which assumes a currency union consisting of two countries with nontradables we study the importance of fiscal policy cooperation as shown in the previous studies we find that the role of fiscal policy is important in maximizing social welfare however we have a contrary result for fiscal policy cooperation while the previous studies highlight that fiscal policy cooperation has a nontrivial effect in maximizing social welfare we show that fiscal policy cooperation has no benefits regardless of the share of nontradables self oriented fiscal policy can replicate social welfare under the cooperative setting

macroeconomic consequences of the real financial nexus imbalances and spillovers between china and the u s relying on quarterly data since 1998 we estimate for china and the u s small scale econometric models that economize on the number of variables employed and yet are rich enough to provide useful insights about spillover effects between the two countries under different maintained assumptions about the exogeneity of the macroeconomic relationship between them we conclude that inflation in china responds to credit shocks indeed the monetary transmission mechanism in china resembles that of the u s even if the channels through which monetary policy affects their respective economies differ we also find that the monetary policy stance of the pboc was helpful in mitigating the impact of the 2008 9 global financial crisis on china s financial conditions finally spillovers from the u s to china are significant and originate from both the real and financial sectors of the u s economy

remaking macroeconomic policy after the global financial crisis a balance sheet approach this paper describes the origins of the global financial crisis and how the prevailing new keynesian macroeconomic orthodoxy failed to anticipate its severity this failure we argue stemmed from an incomplete understanding of the pivotal role of financial institutions in the amplification of the crisis and its transmission to the wider economy low global interest rates and a consequent search for yield in the pre crisis period encouraged financial institutions to build highly leveraged balance sheets which in turn generated extremely large asset price movements when a small event the downturn in the us sub prime mortgage market triggered the crisis the paper then briefly describes the element of the broadly successful and coordinated macroeconomic policy response to the crisis before turning to the medium term challenges facing policymakers in sustaining global recovery at the national level we focus on the resolution of fiscal imbalances which contributed in part to the crisis and which then worsened because of the policy actions which have been taken to deal with it at the international level we emphasise the need to rectifying the imbalances between savings and investment in many significant countries this will require greater coordination of macroeconomic policy across the world s major economies it will also involve strengthening the role and the governance of the international monetary fund

capital flows in the euro area and target2 balances abstract this paper explores how the uneven recourse by national banking systems in the euro area to the ecb s unconventional refinancing operations that led to the accumulation of large target2 balances at the ncbs has contributed to the evolution of aggregate economic activity in important member states of the euro area for the period between 2008 and 2014 we estimate a panel var model and identify the structural shocks by means of sign restrictions our results suggest that the build up of target2 balances was driven mainly by capital flow shocks while being barely responsive to other aggregate shocks furthermore on the basis of counterfactual experiments we find that the ability to build up sizeable target2 liabilities has contributed substantially to avoiding deeper recessions in the distressed euro area member countries like spain italy ireland and portugal while to a smaller extent depressing aggregate economic activity in core member states such as germany the netherlands and finland

optimal monetary policy and sectoral shocks is international monetary cooperation beneficial a stochastic general equilibrium model is used to explore the welfare effects of optimal monetary policy and the potential benefits of policy coordination cross country perfectly symmetric shocks in the traded goods sectors and imperfectly correlated shocks in the nontraded goods sectors are considered in this set up monetary policy may not be able to achieve efficient sectoral resource allocations within countries and avoid inefficient relative price changes across countries welfare gains from coordination are sizable if the shocks to the traded and non traded goods sectors are negatively correlated and both sectors are of roughly equal size

macroeconomic policy transmission and international interdependence a svar application to brazil and us economic policy transmission between trade partners has been analyzed over different contexts in the literature depending on real or nominal frictions the results indicate possible beggar thy neighbor effects for policies given international trade and need for coordinating policies the baseline model is corsetti and pesenti 2001 of macroeconomic interdependence the theoretical proposition suggests that a no anticipated economic policy of exchange rate depreciation creates a beggar thyself effect yet many economies have engaged in this policy to enhance exports and improve welfare here fiscal policy transmissions over brazilian economic aggregates are investigated considering brazil as home and us as foreign country the problem is specified in a structural var vector autoregression model taking granger causality tests and impulse response analysis as econometric applications the results indicate that expansionary fiscal policy in us has a beggar thy neighbor effect for the brazilian economy in the long run the policy transmission mechanism relies on the terms of trade in addition real money balances are affected by foreign fiscal policy affecting the efficiency of domestic monetary policy 2013 national association of postgraduate centers in economics anpec production and hosting by elsevier b v all rights reserved jel classification f41 f42

models of currency crises with self fulfilling features the discomfort a government suffers from speculation against its currency determines the strategic incentives of speculators and the scope for multiple currency market equilibria after describing an illustrative model in which high unemployment may cause an exchange rate crisis with self fulfilling features the paper reviews some other self reinforcing mechanisms recent econometric evidence seems consistent with the practical importance of these mechanisms

friedman redux restricting monetary policy rules to support flexible exchange rates abstract when the currency of export pricing is endogenous there is a social benefit to exchange rate volatility that may be ignored by monetary authorities as a result there is a welfare inferior equilibrium with zero exchange rate pass through and fixed exchange rates this paper shows that there is a simple method of ruling out this equilibrium restrict monetary authorities to respond only to domestic economic conditions

a new bankruptcy procedure that uses multiple auctions abstract we propose a new bankruptcy procedure that makes use of multiple auctions the procedure is designed to work even when capital markets do not function well for example in developing economies or in economies in transition although it can be used in all economies

the expenditure switching effect welfare and monetary policy in a small open economy abstract this paper analyses the implications of the expenditure switching effect for the role of the exchange rate in monetary policy in a small open economy it is shown that when the elasticity of substitution between home and foreign goods is not equal to unity welfare depends on the variances of producer prices and the terms of trade producer price targeting is compared to consumer price targeting and a fixed exchange rate it is found that a fixed exchange rate yields higher welfare than the other regimes only when the elasticity of substitution between home and foreign goods is very high

inflation targeting rules and welfare in an asymmetric currency area abstract this paper studies the effect on monetary policy of differing degrees of competition and differing degrees of nominal rigidity between the members of a monetary union in particular we assess the welfare loss brought about by the use of a simple interest rate rule that does not take into account such structural differences our results show that ceteris paribus to maximize welfare the central bank should react more strongly to inflation pressure generated by the more competitive economies our work extends the results of benigno benigno p 2004 optimal monetary policy in a currency area journal of international economics 63 293 320 by showing that if the degree of competition differs between countries the optimal rule could involve placing a greater weight on the more flexible countries our study suggests that the size of the welfare losses generated by failure to take account of these asymmetries depends crucially on the actual combination of the various asymmetries as a consequence we show that if the optimal weights are chosen under incomplete information regarding the extent and type of asymmetries the resulting level of welfare could be lower than that produced by the symmetric rule

sellers local currency pricing or buyers local currency pricing does it matter for international welfare analysis abstract we study international transmissions and welfare implications of monetary shocks in a two country world with multiple stages of production and multiple border crossings of intermediate goods this empirically relevant feature is important as it has opposite implications for two external spillover effects of a unilateral monetary expansion if all production and trade are assumed to occur in a single stage the conflict of interest terms of trade effect tends to dominate the common interest efficiency improvement effect for reasonable parameter values so that the international welfare effects would depend in general on the underlying assumptions about the currencies of price setting the stretch of production and trade across multiple stages of processing magnifies the efficiency improvement effect and dampens the terms of trade effect thus a monetary expansion can be mutually beneficial regardless of its source or the pricing assumptions

unconventional policies and exchange rate dynamics abstract we study exchange rate dynamics under cooperative and self oriented policies in a two country dsge model with unconventional monetary and exchange rate policies the cooperative solution features a large exchange rate adjustment that cushions the impact of negative shocks and a moderate use of unconventional policy instruments self oriented policies nash equilibrium however entail limited exchange rate movements and an aggressive use of unconventional policies in both countries our results suggest that sizable exchange rate depreciations are not always a symptom of beggar thy neighbor policies they could also reflect a desirable process of external adjustment that improves global welfare

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

openness imperfect exchange rate pass through and monetary policy abstract this paper analyses the implications of imperfect exchange rate pass through for optimal monetary policy in a linearised open economy dynamic general equilibrium model calibrated to euro area data imperfect exchange rate pass through is modelled by assuming sticky import price behaviour the degree of domestic and import price stickiness is estimated by reproducing the empirical identified impulse response of a monetary policy and exchange rate shock conditional on the response of output net trade and the exchange rate it is shown that a central bank that wants to minimise the resource costs of staggered price setting will aim at minimising a weighted average of domestic and import price inflation

oil price stabilization and global welfare abstract oil price stabilization polices are adopted extensively in developing countries some argue that developed economies especially the us may gain from these policies through trade this paper studies this issue in a two country model with dollar currency pricing we find that the optimal level of oil price stabilization chosen by developing countries and its implications for global welfare depend critically on whether monetary policy can effectively respond to oil shocks in an environment without monetary shocks when optimal monetary policies are considered there is no role for oil price stabilization in developing countries however to make the oil price stabilization policy redundant optimal monetary policy is not necessary some non optimal endogenous monetary policies satisfying certain conditions can also make the developing countries choose zero oil price stabilization the results change when there are monetary shocks even with optimal monetary policies the developing countries will choose a positive level of oil price stabilization however due to dollar currency pricing the us actually loses from the stabilization policy our results are well supported by the quantitative analysis in a full fledged dynamic stochastic general equilibrium model

price stability with imperfect financial integration this paper studies whether the international monetary system can be affected by asymmetries in the cross country positions in the international financial markets i e the fact that some countries are large debtors while others are creditors an important channel that is explored is the interaction between international risk sharing and the stabilization role of monetary policy in each country the main finding is that the welfare costs of incomplete markets and the gains of deviating from a policy of price stability are increasing with the cross country asymmetries in the initial net international positions and in particular they become nonnegligible when the persistence of the shocks increases 1 of a permanent shift in steady state consumption for the welfare costs of incomplete markets and 0 2 for the gains of deviating from a policy of price stability when global imbalances become larger optimal monetary policy requires an increase in the volatilities of the real returns on assets and in particular of the nominal interest rates which should happen to be more correlated across countries

optimal financial market integration and security design 1 we study 2 period pure exchange capital asset pricing model capm economies with incomplete financial markets and restricted participation we characterize the optimal financial market structure and efficient innovations consisting of both the introduction of new assets and the integration of segmented markets welfare gains from innovations are maximal when the endowments of affected agents are negatively correlated uncoordinated innovations lead to efficient market structures if all assets have identical participation structure or the markets being integrated trade identical assets however coordination failure in the introduction of new assets may result when assets have participation structures that overlap only partially

optimal monetary policy in open economies revisited abstract this paper revisits optimal monetary policy in open economies in particular focusing on the noncooperative policy game under local currency pricing in a two country dynamic stochastic general equilibrium model we first derive the quadratic loss functions which noncooperative policy makers aim to minimize then we show that noncooperative policy makers face extra trade offs regarding stabilizing real marginal costs induced by deviations from the law of one price under local currency pricing and that optimal monetary policy seeks to stabilize cpi inflation rates and more so under noncooperation than it does under cooperation as a result of the increased number of stabilizing objectives welfare gains from cooperation emerge even when two countries face only technology shocks still gains from cooperation are not large implying that frictions other than nominal rigidities are necessary to strongly recommend cooperation as an important policy framework to increase global welfare

new directions for stochastic open economy models the paper develops a simple stochastic new open economy macroeconomic model based on sticky nominal wages explicit solution of the wage setting problem under uncertainty allows one to analyze the effects of the monetary regime on welfare expected output and the expected terms of trade despite the potential interplay between imperfections due to sticky wages and monopoly the optimal monetary policy rule has a closed form solution to motivate our model we show that observed correlations between terms of trade and exchange rates are more consistent with our traditional assumptions about nominal rigidities than with a popular alternative based on local currency pricing 2000 elsevier science b v all rights reserved

does better information about foreign shocks improve monetary policy abstract this paper examines whether better information about foreign shocks leads to welfare improving monetary policy using a stylised two country new keynesian general equilibrium model we demonstrate that when terms of trade externality exist and national central banks have the incentives to shift terms of trade in their own favour the equilibrium under imperfect information may be welfare superior relative to an equilibrium with perfect information in addition the welfare gains or losses from information sharing between central banks are found to be small for empirically plausible range of parameters for risk aversion and elasticity of labour supply

optimal monetary policy with international trade in intermediate inputs abstract this paper examines optimal monetary policy in a two country new keynesian model with international trade in intermediate inputs we derive the loss function of a cooperative monetary policymaker and find that the optimal monetary policy must target intermediate goods price inflation rates final goods price inflation rates final goods output gaps and relative price gaps we use the welfare loss under the optimal monetary policy as a benchmark to evaluate the welfare implications of three taylor type monetary policy rules a main finding is that the degree of price stickiness at the stage of intermediate goods production is a key factor to determine which policy rule should be followed specifically when the degree of price stickiness at the stage of intermediate goods production is high the policymaker should follow intermediate goods ppi based taylor rule whereas cpi based taylor rule should be followed when the degree of price stickiness at the stage of intermediate goods production is intermediate or low

should the exchange rate be a shock absorber this paper examines the welfare case for the exchange rate as a shock absorber cushioning an economy in face of shocks to world demand for its good we provide an example in which although the exchange rate acts perfectly as a shock absorber stabilizing output around the natural rate and eliminating the impact of nominal rigidities it may in fact be better to prevent the exchange rate from adjusting at all the explanation for this is that with incomplete international financial markets the natural rate is inefficient it does not respond enough to demand shocks while fixing the exchange rate increases the volatility of consumption the pro cyclical nature of monetary policy under a fixed exchange rate allows for a more efficient composition of consumption between home and foreign goods furthermore for the shocks examined a welfare maximizing monetary rule always dampens exchange rate volatility relative to that of a free float and in some cases may imply a fixed exchange rate d 2004 elsevier b v all rigths reserved

international interdependencies in fiscal stabilization policies abstract trade links imply that business cycle fluctuations are transmitted among trade partners to the extent that fiscal policy can mitigate business cycle fluctuations international interdependencies in stabilization policies arise we analyse in a two country general equilibrium model the role of fiscal policy in mitigating risk or providing implicit insurance in the presence of capital market imperfections and adjustment failures rigid wages it is shown that there is a welfare case for an active stabilization policy and that it is larger in the presence of adjustment failures rigid wages non cooperative policy decisions imply inefficiencies in fiscal stabilization policies which in the case of flexible wages may imply too much stabilization whereas stabilization is always insufficient in the case of rigid wages

a currency crisis model with an optimising policymaker abstract a model is presented in which the abandonment of a fixed exchange rate regime is triggered by an optimising policymaker who wants to loosen monetary policy and boost aggregate demand agents in the foreign exchange market know the policymaker s objective function and build expectations of a regime switch into interest differentials the resulting rise in interest rates affects the policymaker s decision to switch regime it is shown that a rational expectations equilibrium exists where the fixed rate is abandoned in response to adverse demand shocks in some circumstances multiple equilibria arise which may lead to self fulfilling crises

home bias exchange rate disconnect and optimal exchange rate policy abstract this paper examines how much the central bank should adjust the interest rate in response to real exchange rate fluctuations the paper first demonstrates in a two country dynamic stochastic general equilibrium dsge model that home bias in consumption is important to replicate the exchange rate volatility and exchange rate disconnect documented in the data when home bias is high the shock to uncovered interest rate parity uip can substantially drive up exchange rate volatility while leaving the volatility of real macroeconomic variables such as gdp almost untouched the model predicts that the volatility of the real exchange rate relative to that of gdp increases with the extent of home bias this relation is supported by the data a second order accurate solution method is employed to find the optimal operational monetary policy rule our model suggests that the monetary authority should not seek to vigorously stabilize exchange rate fluctuations in particular when the central bank does not take a strong stance against the inflation rate exchange rate stabilization may induce substantial welfare loss the model does not detect welfare gain from international monetary cooperation which extends obstfeld and rogoff s obstfeld m rogoff k 2002 global implications of self oriented national monetary rules quarterly journal of economics may 503 535 findings to a dsge model

worldwide macroeconomic stability and monetary policy rules we study the interaction of multiple large economies in dynamic stochastic general equilibrium each economy has a monetary policymaker that attempts to control the economy through the use of a linear nominal interest rate feedback rule we show how the determinacy of worldwide equilibrium depends on the joint behavior of policymakers worldwide we also show how indeterminacy exposes all economies to endogenous volatility even ones where monetary policy may be judged appropriate from a closed economy perspective we construct and discuss two quantitative cases in the 1970s worldwide equilibrium was characterized by a two dimensional indeterminacy despite u s adherence to a version of the taylor principle in the last 15 years worldwide equilibrium was still characterized by a one dimensional indeterminacy leaving all economies exposed to endogenous volatility our analysis provides a rationale for a type of international policy coordination and the gains to coordination in the sense of avoiding indeterminacy may be large

exchange rate policy and endogenous price flexibility most theoretical analysis of exible vs flxed exchange rates takes the degree of nominal rigidity to be independent of the exchange rate regime choice itself but informal policy discussion often suggests that a credible exchange rate peg may increase internal price exibility this paper explores the relationship between exchange rate policy and price exibility in a model where price exibility itself is an endogenous choice of proflt maximizing flrms a flxed exchange rate can afiect the optimal degree of price exibility by altering the volatility of nominal demand facing price setting flrms we flnd that a unilateral peg such as a currency board adopted by a single country will increase internal price exibility perhaps by a large amount on the other hand when an exchange rate peg is supported by bilateral participation of all monetary authorities such as in a monetary union price exibility may actually be less than under freely oating exchange rates quantitatively we flnd that the endogenous increase in price exibility following a unilateral peg might be big enough that output volatility is no greater than it would be under a oating exchange rate regime

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

international portfolios a comparison of solution methods we compare the performance of the perturbation based local portfolio solution method of devereux sutherland 2010a 2011 with a global solution method as a test suite we use model specifications that broadly capture features of international financial trade between advanced economies and between advanced and emerging economies we consider both symmetric country setups and asymmetric setups that capture important empirical facts such as differences in macroeconomic volatility differences in portfolio composition and high equity premia we find that the local method performs well at business cycle frequencies both in the symmetric and asymmetric settings while significant differences arise at long horizons in asymmetric settings

on the benefits of a monetary union does it pay to be bigger this paper revisits the question of the appropriate domain of a currency area using a new keynesian open economy model in which the world is split into two areas each framed as a continuum of small open regions we show that the adoption of a common currency like the euro can be beneficial for the members of the monetary union since the spill over effects generated by the inflationary policies of the small open economies are likely to outweigh the costs of not tailoring monetary policy to country specific shocks we also show that while the enlargement of the monetary union to another group of small open economies can bring about welfare gains for all countries involved monetary integration of two large economies such as the euro area and the u s will not these findings can help to rationalize the process of the creation and enlargement of multi country currency areas like the eurozone

currency areas and monetary coordination we integrate a monetary search model into open economy macro to analyze the gains from coordinating on inflation search frictions and local congestion lead to a determinate exchange rate between two currencies relative prices deviate from the law of one price because the deviations depend on the cross country differential in money growth each country is tempted to inflate to exploit the deviations policy coordination reduces inflation and improves welfare for all countries in contrast to traditional models the gains from coordination continue to exist even after each country optimally sets a direct tax on the foreign use of the country s currency

wage or price based inflation alternative targets in optimal monetary policy rules abstract in this paper the optimality of a specific variant of monetary policy rules a la taylor is tested within a general equilibrium monetary model with both nominal and real rigidities the traditional taylor rule is amended by the inclusion of the growth rate of nominal wage or wage inflation nominal rigidities are inserted via quadratic adjustment costs for both prices and wages a la rotemberg 1982 sticky prices in the united states journal of political economy 90 1187 1211 and kim 2000 constructing and estimating a realistic optimizing model of monetary policy journal of monetary economics 45 329 359 cost of capital adjustment together with a positive steady state inflation rate allow the model to match the main empirical facts about us economy the model is solved by using a second order approximation around the non stochastic steady state as in kim et al 2008 calculating and using second order accurate solutions of discrete time dynamic equilibrium models journal of economic dynamics and control 32 11 3397 3414 the welfare metric is offered by the second order expansion of the utility function conditional to the non stochastic steady state the results show that wage inflation targeting is welfare improving when coupled with inflation targeting moreover optimal monetary rules include also a positive coefficient for output targeting as the need to smooth out quantity adjustments induced by real and nominal rigidities similar results occurs when both targets are in expected value one period ahead the model shows good in sample and out of sample properties

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

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

financial globalization and monetary policy abstract recent data show substantial increases in the size of gross external asset and liability positions the implications of these developments for optimal conduct of monetary policy are analyzed in a standard open economy model which is augmented to allow for endogenous portfolio choice the model shows that monetary policy takes on new importance due to its impact on nominal asset returns nevertheless the case for price stability as an optimal monetary rule remains in fact it is reinforced even without nominal price rigidities price stability is optimal because it enhances the risk sharing properties of nominal bonds

the making of the turkish financial crisis abstract at the turn of the century the turkish economy was in need of an urgent stabilization in order to halt a treacherous process of inflation unsustainable public debt accumulation and increasing financial fragility resulting from irresponsible policies and lack of fiscal discipline that had been endemic since the early 1980s the stabilization program launched with support from the imf has however failed to deliver its promises plunging the economy into an unprecedented recession largely because of serious shortcomings in its design as well as in crisis intervention which appears to have drawn no useful lessons from recent crises in emerging markets

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

welfare effects of a monetary union the role of trade openness this paper evaluates the welfare effects of a monetary union mu compared to a e oating exchange rate regime using a quantitative business cycle model of a two country world with sticky prices it is assumed that under a e oat there are shocks to the uncovered interest rate parity uip condition these shocks are shown to have a negative effect on welfare the detrimental effect is stronger the higher the degree of trade openness a mu eliminates uip shocks and it may thus raise welfare the welfare gain from mu is positively linked to openness jel e4 f3 f4

currency and financial crises in turkey 2000 2001 bad fundamentals or bad luck this paper attempts to explore the underlying causes of twin crises experienced by turkey in november 2000 and february 2001 we study an extensive set of leading indicators of crises that are drawn from the existing literature our results identify three sets of vulnerabilities in the turkish economy in triggering the financial crisis and bringing about the collapse of the turkish lira these are first the weak external position caused by excessive debt burden combined with the loss of competitiveness second the weak fiscal position resulting from the record levels of interest payments on domestic borrowing and most importantly third weaknesses in the financial and banking sector given these observations we argue that the success of financial sector reform is instrumental not only for putting the economy on a sustainable recovery path but also for reducing the likelihood of similar crises in the future the general lesson to be drawn from this experience is that a sound financial system is a pre condition for the successful operation of a fixed exchange rate regime

optimal fiscal transfers in a monetary union abstract we derive the optimal fiscal transfer scheme for countries in a monetary union to offset the welfare losses resulting from asymmetric shocks and nominal rigidities optimal transfers involve a tradeoff between reducing national output gaps and the provision of consumption insurance across countries where the weight of the former increases relative to the latter as consumption home bias rises the welfare gains from optimal transfers increase in wage rigidity and trade elasticities and are particularly large when risk sharing through financial markets breaks down for the average euro area economy the welfare gains from optimal transfers range from 0 50 of permanent consumption under complete markets and low wage rigidity to 6 09 of permanent consumption under financial autarky and high wage rigidity

trade openness and exchange rate regimes the paper evaluates the net welfare gains of inflation targeting over a fixed exchange rate as a function of a country s trade openness using a multisectoral structural model calibrated to chile for most calibrations with separable preferences net welfare gains are increasing in trade openness the reason is that in more open economies terms of trade shocks which favor inflation targeting become quantitatively more important while price markup shocks in the imperfectly competitive nontradables sector which favor exchange rate targeting become less important the most important exception is heavily indebted countries where net welfare gains are decreasing in trade openness

does exchange rate variability matter for welfare a quantitative investigation of stabilization policies abstract this paper studies what degree of exchange rate stabilization is optimal for several types of open economies this is accomplished through a quantitative evaluation of optimal monetary policy rules in a two country sticky price model first a calibrated benchmark model with incomplete asset markets supports past conclusions from simpler models emphasizing inflation stabilization rather than exchange rate stabilization it also highlights that the utility gains from optimal stabilization policy are small second while an economy extended to include consumer habits implies greater sensitivity by households to consumption variability it has only minor effects on the benchmark conclusions and benefits finally these conclusions are altered under an alternative environment where international asset markets exhibit asymmetry in the form of original sin such countries can benefit from policies that aggressively stabilize the exchange rate with utility gains larger than the previous cases

optimal monetary policy cooperation through state independent contracts with targets abstract simple state independent monetary institutions are shown to secure optimal cooperative policies in a stochastic linear quadratic two country world with international policy spill overs and national credibility problems institutions characterize delegation to independent central bankers facing quadratic performance related contracts punishing or rewarding deviations from primary and intermediate policy targets

foreign money shocks and the welfare performance of alternative monetary policy regimes the welfare properties of monetary policy regimes for a country subject to foreign money shocks are examined in a two country sticky price model money targeting is found to be welfare superior to a fixed exchange rate when the expenditure switching effect of exchange rate changes is relatively weak but a fixed rate is superior when the expenditure switching effect is strong however price targeting is superior to both these regimes for all values of the expenditure switching effect a welfare maximising monetary rule yields lower output and exchange rate volatility than price targeting for a wide range of parameter values

an analysis of factors affecting price volatility of the us oil market abstract this paper studies the price volatility of the crude oil market by examining the market structure of opec the stable and unstable demand structure and related elasticity of demand in particular the impacts of prosperity and recession of the world economy and the resulting demand shift on crude oil price are investigated the error correction model is used to estimate the demand relations and related elasticity the income effect on demand functions is evaluated to shed light on future prices a simulation of potential oil prices under different scenarios on a cut of one million barrels per day by opec is evaluated from our simulation given the 4 cut in opec production the oil price is expected to increase unless the recession is severe the magnitude and scope of a price hike would be diminished if non opec or domestic production were greatly expanded

strategic monetary policy in interdependent economies gains from coordination reconsidered abstract there is a wide acceptance that gains to international monetary policy coordination are small at best and that the need of policy coordination is questionable this conclusion however follows from the underlying presumption that monetary policy is concerned with the stabilization of macroeconomic fluctuations only this paper presents a general short run monetary policy analysis within a familiar two country new open economy macroeconomics noem framework where national monetary policy involves the choice of a deterministic growth trend of money supply average inflation rate and stochastic state dependent deviations of actual money supply from the deterministic trend stabilization strategic beggar thy neighbor considerations induce the deviation of both policy choices from their socially optimal values the gains from international coordination of the average inflation rate are of first order and hence larger than the gains from the coordination of the stabilization policies which are of second order

short and long run adjustments in u s petroleum consumption long run adjustments in petroleum consumption are not only larger than short run adjustments they may also be motivated by entirely different price events this analysis shows that new price peaks have both short run and long run consumption responses a result that is starkly different than price changes that track previous price paths it also establishes significant trend effects where gasoline and residual fuel oil consumption decline over time the analysis explores these adjustments by establishing long run cointegrating relationships for different petroleum product groupings an important implication is that price increases above historical levels may be providing substantially greater incentives for significant long run demand adjustments than would be the case otherwise

the g 20 mutual assessment process a perspective from imf staff in the wake of the financial crisis g 20 leaders launched a framework to mutually assess their policies to help strengthen the global economy this article reflects on the experience so far with the mutual assessment process map it looks at the coordination problem facing g 20 economies with respect to the need for global rebalancing of demand while a classic coordination failure has some appeal a more compelling case for policy cooperation is based on the role of spillovers and interdependence in this context the g 20 map as a coordination vehicle has the potential to build shared understanding enhance mutual trust and galvanize action among members simulated gains from collective action are potentially sizeable however key conditions that engendered remarkable global cooperation at the height of the crisis are now more diffuse posing challenges to what the map might achieve going forward and providing some initial lessons for international policy coordination copyright 2013 oxford university press

an aggregate petroleum consumption model abstract this paper presents an aggregative model of us consumption of petroleum and products of a type which might potentially be used to derive short term forecasts of us petroleum consumption and imports the model attempts to separate income and weather related changes from those induced by changes in relative prices with emphasis on the dynamic path of consumption responses to price changes estimation results suggest that there are still significant price effects six years after a change in the relative price of petroleum

the need for international policy coordination what s old what s new what s yet to come the first generation of policy coordination models was introduced some 25 years ago it provided a rationale for policy coordination but the gains from coordination were generally thought to be small now a new generation of policy coordination models is emerging incorporating monopolistic competition and nominal inertia here we examine macroeconomic interdependence and the scope for policy coordination in a tractable second generation model with two countries and multiple sectors initial calibration of the model suggests that second generation models may have more scope for policy coordination than did the first d 2004 elsevier b v all rights reserved

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

global implications of national unconventional policies abstract financial integration in the markets for banks assets and liabilities makes balance sheet constraints highly correlated across countries resulting in a high degree of financial and macroeconomic interdependence likewise under financial integration unconventional policies aimed at stabilizing domestic financial and credit conditions could entail large international spillovers therefore stabilization by one country will also benefit other countries reducing incentives to implement credit policies in a classic free riding problem especially when these policies entail domestic costs we show that this outcome can emerge in an open economy model featuring financial intermediaries that face endogenously determined balance sheet constraints

the role of financial market structure and the trade elasticity for monetary policy in open economies the degree of international risk sharing matters for how monetary policy should optimally be conducted in an open economy this is because risk sharing afiects the way in which monetary policy is afiected by terms of trade considerations in a standard twocountry model with monopolistic competition and nominal rigidities i consider difierent assumptions on international flnancial markets complete markets flnancial autarky and a bond economy and a large region for the crucial parameter of the trade elasticity there are three main results one the prescription of producer price stability as the optimal policy is obtained only as a special case while in general it is optimal to deviate from a strictly zero in ation rate two while gains from international policy coordination are generally small they do become substantial when international risk sharing is poor and wealth efiects from shocks across countries are large and three when international flnancial markets are incomplete there are also sometimes considerable gains over the exible price allocation achievable

a stable international monetary system emerges inflation targeting is bretton woods reversed a stable international monetary system has emerged since the early 1990s a large number of industrial and a growing number of developing countries now have domestic inflation targets administered by independent and transparent central banks these countries place few restrictions on capital mobility and allow their exchange rates to float the domestic focus of monetary policy in these countries does not have any obvious international cost inflation targeters have lower exchange rate volatility and less frequent sudden stops of capital flows than similar countries that do not target inflation inflation targeting countries also do not have current accounts or international reserves that look different from other countries this system was not planned and does not rely on international coordination there is no role for a center country the imf or gold it is durable in contrast to other monetary regimes no country has been forced to abandon an inflation targeting regime succinctly it is the diametric opposite of the post war system bretton woods reversed

metaanalisis de las elasticidades ingreso y precio de la demanda de energia algunas implicaciones de politica publica para america latina the aim of this paper is to analyze the variation in empirical estimates of the income and price elasticities of energy demand the evidence presented through a meta analysis allows identification of the weighted average of the income and price elasticities shows that the estimates are very heterogeneous that there is publication bias and that factors such as region energy sector among others affect its volatility the evidence also indicates that income elasticity in latin america is greater than in the oecd countries and that the price elasticity of energy demand is lower in latin america than in the oecd countries therefore continued economic growth in latin america will be accompanied by a growth in energy demand moreover the establishment of a tax in latin america under the current elasticities is less effective and will be insufficient to control the increase in energy consumption

escaping from a liquidity trap and deflation the foolproof way and others existing proposals to escape from a liquidity trap and deflation including my foolproof way are discussed in the light of the optimal way to escape the optimal way involves three elements 1 an explicit central bank commitment to a higher future price level 2 a concrete action that demonstrates the central bank s commitment induces expectations of a higher future price level and jump starts the economy and 3 an exit strategy that specifies when and how to get back to normal a currency depreciation is a direct consequence of expectations of a higher future price level and hence an excellent indicator of those expectations furthermore an intentional currency depreciation and a crawling peg as in the foolproof way can implement the optimal way and in particular induce the desired expectations of a higher future price level i conclude that the foolproof way is likely to work well for japan which is in a liquidity trap now as well as for the euro area and the united states in case either would fall into a liquidity trap in the future

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

when do cooperation and commitment matter in a monetary union abstract this paper offers a framework to study strategic interactions between private players national fiscal authorities and a common central bank in monetary unions we establish general conditions in terms of restrictions on spillover effects of actions by private and public players under which games that differ in the degree of cooperation and commitment can admit the same equilibrium outcome we use these conditions to characterize benchmark results on the irrelevance of cooperation and commitment established in recent literature moreover we show for a general setting in which the benchmark results do not apply that gains from fiscal cooperation depend on the number of countries and increase as this number gets larger

tests for structural change in us oil consumption 1967 1982 abstract the purpose of this paper is to test us oil consumption for structural change over the period 1967 1982 a frequently used functional form is posited for total petroleum consumption as well as for gasoline distillate and residual fuel tests for abrupt change chow and gradual or conservation like change durbin brown evans and farley hinnich mcguire are employed at special break points 1973 embargo 1979 iranian crisis 1980 recession to check for abrupt changes and across years in general to detect gradual shifts both abrupt and gradual changes are found although the last five years may be the beginning of a new non changing period

political connection bank credits and growth evidence from turkey the pervasive existence of government owned banks in emerging economies is often justified by their provision of access to credit in remote and underdeveloped regions that are ignored by private banks this paper analyses whether credits provided by government owned and private banks have a significant role in regional growth and whether this role changes in politically connected areas in turkey our findings imply that private banks significantly improve the economic well being in all turkish provinces regardless of their development level or their political connection with the ruling party however credits by government owned banks are found to be positively related to the per capita growth rate only in the less developed provinces that are advocates of the ruling political party and also developed but not politically connected provinces these results suggest that government owned bank credits as implied by the political view are used for funding politically desirable projects or politically connected borrowers

policy instrument choice and non coordinated monetary policy in interdependent economies abstract non coordinated monetary policy is analyzed in a stochastic two country general equilibrium model non coordinated equilibria are compared in two cases one where policy is set in terms of state contingent money supply rules and one where policy is set in terms of state contingent nominal interest rate rules in general the non coordinated equilibrium differs between the two types of policy rule but a number of special cases are identified where the equilibria are identical the endogenous choice of policy instrument is analyzed and the nash equilibrium in the choice of policy instrument is shown to depend on the interest elasticity of money demand

energy consumption and economic activity in industrialized countries the dynamic aggregate time series relationship abstract most econometric studies suggest that the income elasticity of demand for energy is approximately unity for the developed market economies it is shown that over the period 1950 1978 the long run income elasticity is substantially higher than unity in terms of a ces energy demand function this result reflects the application of a generalized dynamic estimation methodology where serial correlation is regarded as a diagnostic guide to distributed lag fitting price elasticities are also estimated but these are in line with conventional estimates

collapsing exchange rate regimes some linear examples abstract we construct a pair of linear examples to study the collapse time of a fixed exchange rate regime the first example is a perfect foresight continuous time model which allows calculation of the exact collapse time and the tracking of reserves the second example is a discrete time stochastic model which yields an endogenous probability distribution over the collapse time and produces a forward discount of the exchange rate

the role of intermediate goods in international monetary cooperation abstract this paper investigates the implications of intermediate goods for optimal monetary policy in open economies and particularly focuses on the welfare gains that result from monetary cooperation in a relatively standard two country dynamic stochastic general equilibrium model with input output relations this paper demonstrates that introducing intermediate goods can amplify the welfare gains caused by cost push shocks by an order of magnitude larger a detailed analysis of equilibrium dynamics highlights a new channel that is absent in the previous literature non cooperative central banks respond differently to shocks in the intermediate goods market versus shocks in the final goods market even if these shocks generate the same distortions when the two central banks cooperate furthermore it is demonstrated that increasing the degree of openness in the intermediate goods market can reduce the welfare gains from monetary cooperation this casts doubt on whether the recent trend in international economic integration justifies the potential need for international monetary cooperation

liberalising foreign trade through rose tinted glasses the foreign trade sector has a crucial role to play in economic development trade has variously been described as the engine or handmaiden of growth this key role has stimulated a great deal of interest in the links between trade and growth with the links between trade orientation and exports and exports and growth receiving particularly close attention alongside this time series work there have been a number of multi country studies of trade policy in developing countries those of krueger i 98 i and balassa i 982 are perhaps the best known most of this work has been directed at two questions first what does the structure of protection look like in a given developing country second are there clear links between the structure of protection trade orientation and economic performance it is widely believed in developing countries that the major lending agencies the world bank in particular perceive a clear link between trade orientation and economic performance and that this explains why around three quarters ofall conditions which attach to structural adjustment loans sals feature reform of trade policy the editors of liberalising foreign trade demetrious papageorgiou michael michaely and armeane choksi all of whom are on the world bank staff clearly believe this to be the case judging from their opening statement the benefits of open trading have by now been sufficiently demonstrated and described by economic historians and analysts in this study we take them for granted and turn our minds from the whether to the how vol i p vii in other words it is the timing phasing and sequencing involved in the design and implementation of a trade liberalisation policy that forms the subject matter of the present study vol 7 p i liberalising foreign trade is a world bank organised study which describes and evaluates 36 liberalisation episodes in i 9 countries during the period i950 i982 the study is ambitious in scale28 authors 3 editors 7 volumes and almost 3 ooo pages of text it is the most comprehensive cross country analysis of liberalisation episodes undertaken from a policy perspective a study of this scale is potentially of considerable interest given the liberalisations

oil currency and the dollar standard a simple analytical model of an international trade currency the u s dollar is the central reference currency for international trade pricing and the main invoicing currency for primary commodities this paper links these two observations within a stylized theoretical framework and shows how to obtain a quantitative estimate of the gain to the u s economy when the dollar is a reference currency with dollar invoicing of primary commodities u s firms bear less exchange rate risk than foreign firms this asymmetry leads to a dollar standard in international goods pricing we then derive a simple analytical formula to calculate the gains and find that they are extremely small

on constraining fiscal policy discretion in emu we review the theoretical and empirical literature on the benefits and costs of imposing restrictions on fiscal policy we emphasize that the arguments in favour of restricting discretion of fiscal policy go beyond the notion of avoiding unsustainable budgetary plans that can lead to pressure on the central bank restrictions on fiscal policy can also be justified on the grounds that discretionary changes in spending or taxes can lead to unnecessary volatility in output and lower economic growth empirically there is evidence that implicit constraints on governments can be as effective as explicit constraints i e rules from the analysis in emu countries in the last 10 years we conclude that there has been a significant change in the conduct of fiscal policy in terms of increased discipline and less use of discretion however since 1999 there are clear signs of fatigue in this process as previous trends have either stopped or even reversed copyright 2003 oxford university press

backcasting u s oil demand over a turbulent decade abstract this paper compares 10 year backcast projections of u s petroleum consumption for the 2000 2009 period based upon a range of functional forms although a univariate specification based upon only lagged consumption performed better than most approaches it provides little value to the policymaker who wants to understand the factors that influence oil consumption and by how much one structural approach performed considerably better than all other approaches including the univariate model this specification is the autoregressive distributed lag adl model that allowed oil demand to respond differently asymmetrically to price increases and decreases certain forms of this equation however do well while others perform poorly evaluations of backcast projections over different periods and updated frequently can be important byproducts of energy modeling

the welfare effect of international asset market integration under nominal rigidities abstract this paper assesses the impact of integrating international asset markets when segmented markets are not the only distortion using a two country general equilibrium model with nominal rigidities and monetary shocks we show that integration is not universally beneficial instead the welfare impact depends on the degree to which exchange rate fluctuations are passed through to consumer prices while the integration is welfare neutral in the polar cases of complete or zero pass through this is not the case when pass through is partial when shocks are equally volatile in both countries integration can be detrimental or beneficial depending on the degree of pass through when shocks are more volatile in one country it benefits from integration compared with the more stable country

transmission of nominal exchange rate changes to export prices and trade flows and implications for exchange rate policy we discuss how the welfare ranking of fixed and flexible exchange rate regimes in a new open economy macroeconomics model depends on the interplay between the degree of exchange rate pass through and the elasticity of substitution between home and foreign goods we identify combinations of these two parameters for which flexible and fixed exchange rates are superior with respect to welfare as measured by a representative household s utility level we estimate the two parameters for six non emu european countries czech republic hungary poland slovakia sweden and the uk using a heterogeneous dynamic panel approach

a single equation study of u s petroleum consumption the role of model specification the price responsiveness of u s petroleum consumption began to attract a great deal of attention following the unexpected and substantial oil price increases of 1973 74 there have been a number of large multi equation econometric studies of u s energy demand since then which have focused primarily on estimating short run and long run price and income elasticities of individual energy resources coal oil natural gas electricity for various consumer sectors residential industrial commercial following these early multi equation studies there have been several single equation studies of aggregate u s petroleum consumption 4 3 9 5 6 these singleequation studies have found that u s demand for petroleum products can be quite price inelastic in the short run estimates range from 0 04 to 0 08 but exhibits long lags of anywhere from 6 to 10 years that yield long run price elasticities ranging from 0 25 to 0 56 income or gnp elasticities are usually found to be much higher 0 69 to 1 13 with the complete response often assumed to occur in the current period single equation studies are often justified as efficient shortcuts or reduced forms for identifying the central behavioral aspects of a particular market the main issue addressed in this paper is the extent to which the existing empirical results from single equation studies of aggregate u s petroleum consumption have been influenced by the researchers choice of dynamic model specification this question is relevant because the econometric methodology usually followed in such studies is to start with a relatively simple specification such as a partial adjustment model or some kind of a distributed lag structure on price alone this initial specification choice is rarely justified except possibly to cite its previous success in similar work given that models which produce insignificant or perverse coefficient estimates are not usually publishable the reported specification is almost certain to provide reasonable statistically significant estimates with the correct signs the primary diagnostic test of the chosen specification is the durbin watson test statistic or perhaps durbin s h statistic in the presence of lagged dependent variables when this test gives evidence of serial correlation in the residuals the usual response is to correct for this by estimating a first or second order autoregressive model ar 1 or ar 2 should this easilyimplemented correction not solve the problem there is a tendency to chalk it up to some kind 1 an excellent survey of these results may be found in bohi 2 159

dynamic firm behavior and regional deadweight losses from a u s oil import fee this paper analyzes the national and regional efficiency aspects of a 5 per barrel fee on crude oil imported into the united states the emphasis of the paper is twofold firstly a dynamic model of firm behavior capturing explicitly both expectations formation and resource nonrenewability is used to assess the impact of the fee on domestic firm behavior and secondly the regional breakdown of the producer and consumer surplus changes tariff revenues and deadweight losses or gains is performed by taking explicit account of stock ownership in oil producing and oilconsuming corporations and consumption by end use sector the import fee is a politically contentious issue but one that refuses to go away in political circles the perceived benefits of the fee are usually seen as increased energy security and aid to a beleaguered domestic oil and gas industry perceived drawbacks are usually inflation and regional inequities the last point is the political downfall of the tariff producing states are seen to gain from the higher prices brought on by the tariff and consuming states are seen to lose representatives from states with little or no production and this of course covers most states are hard pressed to sell the idea to constituents this paper thus deals with two of the most important questions from a policy perspective the regional incidence of the tariff and its impact on domestic output in a related paper 20 i discuss the economic rationales for an oil import fee i find that any optimal tariff arguments based on u s monopsony power in the world oil market are not valid in today s market estimates show an import supply curve of approximately infinite elasticity and thus an optimal tariff near zero i dispense with the energy security rationale for a tariff as well arguing that any risk of a disruption of imports in the future and that risk may be small in today s market is best handled with other policy tools such as government owned or subsidized stockpiles these conclusions imply that a tariff would impose deadweight losses on the u s economy by encouraging overproduction of domestic petroleum resources and underconsumption of petroleum imports how much overproduction results from the tariff is the focus of section ii below a

policy measures to avoid a currency crisis this paper considers a number of policy measures that may be used to preserve a fixed exchange rate these are analyzed in a model where a switch of exchange rate regime is triggered by an optimizing policymaker in response to extreme economic conditions it is shown how a number of policy measures can be used to alter the balance between the costs and benefits of switching between regimes these policy measures have both a direct effect on the policymaker s choice of regime switching point and an indirect effect through private sector expectations of a regime switch copyright 1995 by royal economic society
