Monetary union: A welfare based approach

This article attempts to shed light on the consequences of the transition to EMU for individual welfare following specific shocks. To this end, we develop a two country intertemporal general equilibrium model that extends the Obstfeld and Rogoff (Journal of Political Economy 103 (3) (1995) 624) specification to nominal rigidities through price adjustment costs and pricing-to-market behavior.We show that, when facing a positive asymmetric permanent shock to either technology or government expenditures occurring in one country, implementing a monetary union is beneficial to the households living in this economy. Conversely, it is detrimental to foreigners. Further, a sensitivity analysis shows that if the gains/losses to implementing monetary union are qualitatively robust when facing changes in the degree of nominal rigidities and the elasticity of substitution between foreign and domestic goods, they are quite sensitive to the degree of pricing-to-market in the economy.     

International transmission of environmental policy: A New Keynesian perspective

In this paper we examine the international transmission of environmental policy using a New Keynesian model of the global economy. We first consider the case in which the quality of the environment affects utility, but not productivity. This allows us to look at the trade-off between environmental quality and output. We then consider the case in which the quality of the environment increases productivity but does not affect utility. Our main results show that in both cases a unilateral implementation of a more stringent environmental policy by the domestic country raises foreign welfare under a benchmark parameterization. Our modeling strategy allows an analysis of how nominal rigidities interact with the implementation of environmental reforms, by allowing the domestic country to shift, through exchange rate depreciation, parts of the costs of more stringent environmental policies to the foreign one.     

Real exchange rates,asset prices and terms of trade: A theoretical analysis

This paper develops a continuous-time two-country dynamic equilibrium model, in which the real exchange rates, asset prices, and terms of trade are jointly determined in the presence of nontradable goods. The model determines the relation between the financial markets and real goods markets in the world economy and their responses to various shocks under the home bias assumption. A positive domestic supply shock induces a positive return on the domestic asset markets and a deterioration of terms of trade that improves the foreign output and boosts the foreign asset markets. Demand shocks act in the opposite way. This model also analyses the impact of change in the relative price of nontradable to tradable goods on the terms of trade and asset markets. A higher productivity growth in tradable goods than in nontradable goods leads to a higher relative price of nontradable to tradable goods, which appreciates the real exchange rate, deteriorates the terms of trade, and depresses the domestic and foreign asset markets. A lower relative price of nontradable goods depreciates the real exchange rate, improves the terms of trade, and lifts both the domestic and foreign asset markets.     

The optimal choice of monetary policy instruments in a small open economy

Abstract.  This paper studies how the nature of shocks affects the optimal choice of monetary policy instruments in a small open economy. Three classic rules, fixed exchange rates, monetary targeting, and inflation targeting are studied and ranked by comparing with the optimal monetary policy under commitment. We find that the ranking of the simple rules can be mapped to the terms-of-trade variability that the rule allows relative to what a particular shock optimally calls for. It turns out that inflation targeting dominates the other two rules under productivity or velocity shocks, whereas monetary targeting is the best performer under fiscal shocks.     

European monetary union, adjustment, and exchange rate variability

This paper uses a three-country, three-good, factor-specific model of trade with wage rigidities to investigate how European Monetary Union is likely to affect exchange rate variability. Focusing on international macroeconomic adjustment under both exogenous and optimizing monetary policies, it shows that the relative variability (against external currencies) of the euro and a basket of predecessor currencies depends on the relative sizes and specialization patterns of countries and the relative importance of different shocks. Monetary union is likely to decrease (increase) aggregate European exchange rate variability for shocks to industries in which large (small) euro area countries specialize.     

Potential economic reforms in North Korea: a dynamic general equilibrium model

We use a dynamic general equilibrium model to examine hypothetical market reforms in North Korea. We model partial reform, in which producers choose capital allocations across sectors, with the government still fixing total capital. We also consider two full market reform scenarios. In one, public infrastructure investment remains unchanged, while, in the other, it increases substantially. In all scenarios, we assume a closed economy and a constant military size. Our simulations show little hope for the North Korean economy without boosting infrastructure. Although all of the reforms raise consumption, only significant increases in infrastructure investment bring positive economic growth.     

Equity home bias,incomplete financial markets,and nominal rigidities

Abstract This paper analyzes optimal portfolio decisions in a monetary open‐economy framework. It is found that market completeness and the specific form of nominal rigidities, namely, nominal price vs. nominal wage rigidities, matter for justifying the observed structure of equity holdings. When markets are complete, sticky prices generate a negative correlation between the non‐diversifiable labour income and the profit of domestic firms with respect to the productivity shocks, which explains why households invest little abroad. In contrast, when markets are incomplete, rigidities in goods prices result in a counterfactual ‘super home bias’, because domestic equities provide a good hedge against not only the labour income risk but also the relative price risk. Wage rigidities, however, have the opposite effect. Therefore, nominal rigidities in both goods prices and wage rates are needed to address the empirical composition of gross equity positions under incomplete markets.     

Nonlinear dynamics in exchange rate deviations from the monetary fundamentals: An empirical study

This paper reexamines empirical performance of the monetary exchange rate model with nonlinear dynamics of exchange rate deviation from the monetary fundamentals. First, we apply unit root test of Park and Shintani (2005) to post-Bretton Woods exchange rate data and able to reject the null of unit root deviation from monetary fundamentals against alternative hypothesis of nonlinear stationary process for deutschemark, pound, and Swiss franc. Our empirical results find that exchange rates show high degree of mean-reversion with larger deviation and long periods of overvaluation and undervaluation of dollar. We also find empirical evidence of predictability of the monetary fundamentals at longer horizons.     

Policy analysis in real time using IMF's monetary model

We investigate to what extent estimated relationships of the IMF's monetary model and their policy implications are sample dependent. We observe that estimates of the model's key parameters and model-based measures of macroeconomic disequilibria are highly dependent on the data vintage employed. Changes in parameter estimates solely due to data revisions are found to be much smaller than those owing to parameter instability, possibly reflecting model misspecification. Moreover, instability in parameter estimates contributes to more uncertainty in assessments of macroeconomic disequilibria than data revisions. Analyses based on a version of the model in difference form are also found to be quite sensitive to the data vintage employed, although to a lesser extent than those based on the standard version of the model with variables in levels.     

Liquidity risk, economic development, and the effects of monetary policy

Empirical evidence indicates that monetary policy is not super-neutral in many countries. In particular, in high inflation economies, inflation is negatively related to economic activity. By comparison, inflation may be positively correlated with output in low inflation countries. We present a neoclassical growth model with money in which the incidence of liquidity risk is inversely related to aggregate capital formation. Interestingly, there may be multiple monetary steady-states where the effects of monetary policy vary. In poor economies, the financial system is highly distorted and higher rates of money growth are associated with less capital formation. In contrast, in advanced economies, a Tobin effect is observed. Since inflation exacerbates distortions from a coordination failure in the low-capital steady-state, individuals become much more exposed to liquidity risk. Consequently, optimal monetary policy depends on the level of development.     

Globalization, the output-inflation tradeoff and inflation

This paper provides comprehensive evidence on the relation between inflation and globalization, defined here as trade and financial openness, using a large cross-section of 91 countries over the period 1985-2004. We establish two main empirical regularities: both higher trade and financial openness (i) reduce central banks’ inflation bias, yielding lower average inflation and (ii) are associated with a larger output-inflation tradeoff. This evidence is at odds with the standard Barro-Gordon framework, which would require globalization to have a negative effect on the output-inflation tradeoff to yield lower equilibrium inflation, but it is consistent with a recent strand of new Keynesian models emphasizing the role of imperfect competition and nominal rigidities. Our findings also support the relevance of the time-inconsistency hypothesis, which underlies the theoretical models predicting a relation between globalization and inflation. For the OECD subsample, however, we do not find an effect of openness on inflation (the output-inflation tradeoff), suggesting that these countries have created an institutional framework for central banks that eliminates distortions due to the time-inconsistency problem.     

Fiscal inertia, donor credibility, and the monetary management of aid surges

Donors cannot pre-commit to support scaled-up public spending programs on a continuing basis, nor can governments credibly commit to curtail expenditure rapidly in the event that aid revenues contract. An aid boom may therefore be accompanied by a credibility problem. When this is the case, the absorb-and-spend strategy recommended by the IMF leads to capital flight, higher inflation, and large current account surpluses inclusive of aid. The right policy package combines a critical minimum degree of fiscal restraint with reverse sterilization.     

International portfolio reallocation: Diversification benefits and European monetary union

We investigate the determinants of bilateral international equity and bond portfolio reallocation across a large cross-section of countries spanning over two sample periods: 1997-2001 and 1997-2005. We find that the strongest drivers are the marginal diversification benefits arising from the pure asset component and the initial degree of underweight. This evidence suggests that global portfolio reallocations over the asset boom and bust period were determined by optimal diversification considerations. We also find that due to economic and monetary union (EMU) the weight assigned by euro area investors to investment in euro area countries increased significantly in equity and fixed income portfolios, with a trade diverting effect against the British bond market.     

The behaviour of relative prices in the European Union: A sectoral analysis

Using multivariate unit root test methods, this paper investigates the Purchasing Power Parity (PPP) hypothesis at the sectoral level across six European countries over the last 17 years. Evidence of mean reversion towards PPP is found for the relative prices of some sectors and countries. Mean reversion in relative prices is explained by cross-country and cross-sectoral characteristics such as the distance between countries, nominal exchange rate volatility, differences in GDP per capita, non-tariff barriers, research and development, advertising, industrial concentration and tradeability of the products.     

Investment-specific shocks and external balances in a small open economy model

Abstract.  We set up a standard small open economy business cycle model driven by government spending shocks, neutral productivity (TFP) shocks, and investment-specific shocks. The model is calibrated to quarterly Canadian data and its predicted moments and sample paths are compared with their Canadian counterparts. We find that the model captures the dynamics in investment and in the trade balance better than special cases of the model where either one of the productivity shocks is omitted. More specifically, the model matches the variance of the trade balance-output ratio, its correlation with output and its autocorrelation. It also matches the output-investment correlation.     

The coordination channel of foreign exchange intervention: A nonlinear microstructural analysis

Taylor (1994, 1995) [Taylor, M.P., 1994. Exchange rate behaviour under alternative exchange rate regimes. In: Kenen, P. (Ed.), Understanding Interdependence: The Macroeconomics of the Open Economy. Princeton University Press, Princeton; Taylor, M.P., 1995. The economics of exchange rates. Journal of Economic Literature 33, 13-47] has proposed the coordination channel as a means by which foreign exchange market intervention may be effective, in addition to the traditional portfolio balance and signalling channels. If strong and persistent misalignments of the exchange rate are caused by nonfundamental influences, such that a return to equilibrium is hampered by a coordination failure among fundamentals-based traders, then official intervention may act as a coordinating signal, encouraging stabilising speculators to re-enter the market at the same time. We develop this idea in the framework of a simple microstructural model of exchange rate movements, which we then estimate using daily data on the dollar-mark exchange rate and on Federal Reserve and Bundesbank intervention operations. The results are supportive of the existence of a coordination channel of intervention effectiveness.     

Macroeconomic dynamics in Macedonia and Slovakia: Structural estimation and comparison

This paper estimates a structural macroeconomic model using data for Macedonia and Slovakia to characterize possible challenges Macedonia can face concerning macroeconomic stabilization during its transition process. A comparison of the estimated model parameters suggests that, in Slovakia, the output gap is less sensitive to real interest rate movements and prices experience greater inertia. The estimated monetary policy reaction functions show Macedonia and Slovakia as inflation targeters, with Macedonia as the more conservative one, despite its officially applied exchange rate targeting regime. The differences in the estimated parameters imply differing transmission mechanisms for Macedonia and Slovakia. Consequently, the variance of domestic variables in Slovakia is most influenced by monetary policy shocks, while there is no single dominating shock explaining the volatility of Macedonia's macroeconomic variables. The exchange rate shock, the monetary policy shock and the demand shock are jointly important in determining the volatility of Macedonia's variables. The model simulations indicate that Macedonia experiences lower output gap and inflation volatility than Slovakia. This comes, nevertheless, at the cost of higher interest rate and real exchange rate volatility in Macedonia, which could be an indication of more volatile financial markets with possible negative implications for financial stability.     

The long-run convergence of exchange rates and prices in the European Union

This paper provides tests of Purchasing Power Parity (PPP) for members of the EU-27 not in the euro area, using multivariate and panel cointegration techniques, for the period since the introduction of the euro currency in 1999 until the end of 2009. The results indicate that long-run PPP holds in ten cases and that domestic prices or the nominal exchange rate is the main driver of the short-run adjustment to stationarity. These results are discussed in terms of monetary convergence in the long-run.     

The Hidden Structural Features of the Fiscal Rule: A European Saga

This paper addresses the question of the reform of the Stability and Growth Pact (SGP). More and more authors and policymakers are bringing to light the negative impacts of the European deficit rule on the countries and their ability to respond asymmetric economic shocks, and some are asking for a redefinition of the pact. If the focus of the SGP is only fiscal, and two of the biggest countries in Europe have failed to abide by the pact since its implementation, it seems clear that the SGP needs at least a re-examination. Yet, on the contrary, if we introduce into the analytical framework the SGPs impacts on the European Unions structural policies, the conclusions are far different. Abolishing the SGP could hinder the presently up-to-date convergence prospective. This paper proposes a theoretical analysis of the SGP that emphasizes a new feature of the SGP: a strong incentive to structural reforms.The author would like to thank the participants of the International Atlantic Economic Conference in Quebec City (Oct. 16–19, 2003) for their helpful comments, Kenneth Donahue, and two anonymous referees.

Tariffs,Offshoring and Unemployment in A Two‐Country Model

This paper develops a two‐country model that incorporates offshoring opportunities, and analyses the effects of tariffs under economic stagnation in a liquidity trap that causes unemployment. We find that a rise in tariffs on imports of outsourced goods contributes to an increase in employment by inducing a shift in production, but also leads to an appreciation of the real exchange rate that tends to reduce employment. The effect of real exchange rate appreciation dominates the effect of the production shift, and accordingly employment and consumption fall. The effects of tariff adjustments are reversed, however, when there is no liquidity trap and hence no unemployment.
