monetary policy in open economies abstract the recent literature on monetary policy in open economies has produced a strong presumption in favor of activistic policy and flexible exchange rates we argue that this result may owe much to the combination of two commonly made assumptions that nominal goods prices are rigid and that the monetary authorities have a lot of information about the economy when the source of nominal rigidity is found in wages and monetary policy is conducted according to less information demanding rules such as a standard interest rate rule policies that stabilize the money supply or the nominal exchange rate may perform better

optimal monetary policy in a currency area abstract this paper investigates how monetary policy should be conducted in a two region general equilibrium model with monopolistic competition and price stickiness this framework delivers a simple welfare criterion based on the utility of the consumers that can be used to evaluate monetary policy in a currency area if the two regions share the same degree of nominal rigidity the terms of trade are completely insulated from monetary policy and the optimal outcome is obtained by targeting a weighted average of the regional inflation rates these weights coincide with the economic sizes of the region if the degrees of rigidity are different the optimal plan implies a high degree of inertia in the inflation rate but an inflation targeting policy in which higher weight is given to the inflation in the region with higher degree of nominal rigidity is nearly optimal

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

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

aggregate spending and the terms of trade is there a laursen metzler effect this paper investigates the spending and current account effects of terms of trade shifts in a model where households maximize utility over an infinite planning period in the framework developed here an economy specialized in production must experience a fall in aggregate spending and a current surplus as a result of an unanticipated permanent worsening in its terms of trade the paper s model thus provides a setting in which the current account deficit predicted by laursen and metzier harberger and others fails to materialize

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

ldc agriculture nonparametric malmquist productivity indexes abstract this paper examines changes in agricultural productivity in 18 developing countries over the period 1961 1985 we use the nonparametric output based malmquist index to examine whether the results from such an approach confirm results from other methods that have indicated declining agricultural productivity in less developed countries ldcs the results confirm previous findings indicating that at least half of these countries have experienced productivity declines in agriculture we also found that those countries that tax agriculture most heavily had the most negative rates of productivity change

the terms of trade and the current account the harberger laursen metzler effect the paper examines the effect of terms of trade changes on a small country s spending and current account assuming optimizing behavior in an intertemporal framework with perfect international capital mobility a temporary future terms of trade deterioration implies a deterioration improvement of the trade balance whereas a permanent terms of trade deterioration has an ambiguous effect depending on the rate of time preference nominal and real variables are considered via exact price indexes two periods and an infinite horizon are examined

do the ecb and the fed really need to cooperate optimal monetary policy in a two country world abstract a two country model with monopolistic competition and price stickiness is employed to investigate the implications for macroeconomic stability and the welfare properties of three international policy arrangements a cooperative b non cooperative and c monetary union i characterize the conditions under which there is scope for policy cooperation and quantify the costs of non cooperation and monetary union the non cooperative equilibrium may be suboptimal because of terms of trade spillover effects while monetary union may be suboptimal because of the sluggishness of relative prices both the costs of policy competition and of a monetary union are sensitive to the values assumed for the intertemporal and international demand elasticity and the degree of openness of the economy independently of the calibration scenario adopted the ecb has little to gain by coordinating with the fed

the j curve a literature review due to lag structure currency devaluation is said to worsen the trade balance first and improve it later resulting in a pattern that resemble the letter j hence the j curve phenomenon since its introduction by magee in 1973 brooking papers on economic activity 1 pp 303 25 a large number of studies have attempted to test the phenomenon using different techniques and different model specifications the results are at best ambiguous and deserve to be collected together for the future generation of researchers and graduate students this paper fills such a vacuum in the literature by reviewing the j curve related empirical papers

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

deterioration of the terms of trade and capital accumulation a reexamination of the laursen metzler effect abstract this paper analyzes the effect of both a permanent and a temporary deterioration in the terms of trade on a small open economy the model based on intertemporal optimization emphasizes the labor leisure choice and the role of capital accumulation the transitional dynamics is shown to depend upon the long run response of the capital stock to the terms of trade shock this consists of a negative substitution effect together with a positive income effect whether or not the laursen metzler effect holds depends upon whether the income effect dominates the substitution effect

international business cycles the authors estimate a dynamic two country model in which economic fluctuations are driven by a worldwide supply shock country specific supply shocks and relative fiscal money and preference shocks identification is achieved using only long run restrictions based on a theoretical model the main results are 1 supply shocks particularly country specific ones are very important in generating international business cycles and 2 although the post 1973 flexible exchange rate period has been inherently more volatile there are no differences in transmission properties of economic disturbances across exchange rate regimes for the endogenous variables they focus on copyright 1993 by american economic association

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

public and private sector wages interactions in a general equilibrium model it is common wisdom that public sector wages are not determined in the same way as private sector wages at the same time the empirical evidence available for oecd countries finds a strong positive correlation between public and private sector wages in this paper we develop a model that is consistent with a political economy view of the determination of public sector wages and employment while being consistent with the said empirical evidence public finance constraints are crucial in booms governments expand employment and wages while in downturns lack of tax revenues forces the government to cut back the wage bill

indicator variables for optimal policy under asymmetric information the optimal weights on indicators in models with partial information about the state of the economy and forward looking variables are derived and interpreted both for equilibria under discretion and under commitment the private sector is assumed to have more information about the state of the economy than the policymaker certainty equivalence holds for the optimal reaction function in state space form t he coefficients are independent of the degree of uncertainty about the state of the economy however in the case of commitment certainty equivalence does not hold for the reaction function in integrative form the policy instrument cannot be written as a distributed lag of past estimates of past states of the economy instead optimal policy will generally depend on new estimates of past states of the economy and in ways that depend on the information structure furthermore the usual separation principle does not hold since the estimation of the state of the economy is not independent of optimization and is in general quite complex we present a general characterization of optimal filtering and control in settings of this kind and discuss an application of our methods to the problem of the optimal use of real time macroeconomic data in the conduct of monetary policy

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 exchange rate in a dynamic optimizing business cycle model with nominal rigidities a quantitative investigation this paper studies a quantitative dynamic optimizing business cycle model of a small open economy with staggered price and wage setting the model exhibits exchange rate overshooting in response to money supply shocks the predicted variability of the nominal and especially of the real exchange rate is noticeably higher than in standard real business cycle models with flexible prices and wages a positive domestic money supply shock is predicted to lower the domestic interest rate raise gdp and trigger a depreciation of both the nominal and real exchange rate increases in domestic productivity and in the world interest rate are also predicted to induce a nominal and real exchange rate depreciation 2001 elsevier science b v all rights reserved

should central banks target consumer prices or the exchange rate in this article we consider two arguments suggesting that monetary authorities in an open economy should target output price inflation and not consumer price inflation the first suggests that output price inflation corresponds to the distortions caused by price rigidity the second shows how policy rules involving consumer price inflation can induce instability because of the feedback from interest rates to consumer price inflation via the exchange rate we examine both arguments in the context of an open economy which is subject to a range of shocks we show that both arguments remain robust but that there is a case for including a terms of trade or real exchange rate gap term in the authorities welfare function alongside the output gap and output price inflation

import prices export prices and the current account an asymmetry abstract we demonstrate that there is an important asymmetry between the effects of temporary import and export price shocks on the current account that is ignored in theoretical and empirical work this asymmetry is found to hold for u s and u k data

structural adjustment to a terms of trade disturbance the role of relative prices abstract this paper investigates the impact of a terms of trade disturbance on a small economy which responds gradually to changes in relative prices the key intertemporal link is as in dornbusch 1983 between the price of nontraded goods the real interest rate savings and the current account if the traded and nontraded goods are bad substitutes in consumption then an improvement in the terms of trade leads to a transitory current account surplus and conversely international capital mobility reduces the impact of a terms of trade disturbance on relative prices and also reduces the speed with which the economy adjusts to the disturbance

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

the political economy of policies for smallholder agriculture summary as the experience of the 20th century has shown implementing policies that increase agricultural productivity among smallholders is a particularly promising strategy to achieve pro poor growth however history also reveals major political challenges to adopting this strategy the paper compares the experience of asian countries that were able to launch a smallholder based green revolution with the experience of african countries that are still struggling with this goal it then reviews the political economy literature to identify the factors that account for these divergent experiences finally the paper develops a conceptual framework to guide empirical research to close the knowledge gaps identified by the review

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

common currencies vs monetary independence we study the optimal monetary policy in a two country open economy model under two monetary arrangements a multiple currencies controlled by independent policy makers b common currencies with a centralized policy maker our findings suggest that i monetary policy competition leads to higher long term inflation and interest rates with large welfare losses ii the inflation bias and the consequent losses are larger when countries are unable to commit to future policies iii the welfare losses from higher long term inflation dominates the welfare costs of losing the ability to react optimally to shocks

factor content functions and the theory of international trade this paper introduces the concepts of direct and indirect factor trade utility functions and uses them to derive marshallian and hicksian factor content functions which express the quantities of factors of production embodied in net imports as functions of the exogenous variables facing the economy the properties of these functions are discussed and they are used to derive a number of new results in particular it is shown that in certain circumstances the existence of gains from trade is sufficient for the heckscher ohlin theorem to hold in its factor content form

trade interdependence and the international business cycle a stochastic general equilibrium model of the world economy is developed to analyze the contribution of trade interdependence to international business cycles we test some of the implications of the model using data from ten major industrial countries and a variety of detrending techniques to calculate the cyclical component of output we find that the significance of trade in the transmission of economic disturbances across countries is not robust to the choice of the detrending method in general the role of trade interdependence is moderate and seem to have been stronger in the period before 1973

the dynamic efficiency of regulatory constitutions in this article we model regulation as a repeated game between a utility facing a random sequence of demands and a regulator tempted to underreward past investment rate of return regulation designed with a constitutional commitment to an adequate rate of return on capital prudently invested is able to support an efficient investment program as a subgame perfect nash equilibrium for a larger set of parameter values than rate of return regulation without such a commitment furthermore rate of return regulation is superior to price regulation according to the same criterion assuming that the regulator is unable to make state contingent transfer payments

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
