The New Member States and the Process towards EMU

The authors apply two complementary empirical criteria to eight new member states (NMSs) of the European Union to assess how ready they are to adopt the euro. As a first step, they recover demand and supply shocks and calculate the social losses implied by the two relevant exchange rate regimes: flexible rates and currency board. As a second step, the authors calculate the real exchange rates variability that these countries are currently experiencing and compare it to that of three Mediterranean countries during a similar period before they joined the EMU. The combination of the results of both tests shows that Estonia and Slovenia are the only countries that seem ready to adopt the euro within the shortest period of time foreseen by the Maastricht criteria; that is, after the two mandatory years in the ERM2. The rest of the countries will probably still need some exchange rate flexibility to absorb external shocks in the coming years.     

Macroeconomic shocks under alternative exchange rate regimes: the Irish experience

The paper investigates the nature of Irish macroeconomic shocks and their correlation with German and UK shocks. A restricted VAR of real output and prices is employed to distinguish aggregate demand and supply shocks for the three countries. To identify the role of Irish exchange rate policy two periods are considered: the preERM period and the ERM period. The results indicate that while the change in exchange rate policy had an effect on the nature of demand and supply shocks, the ERM did not have the effect of increasing the correlation of Irish shocks with Germany or the UK. Evidence of substantial asymmetric shocks with Germany and the UK exist. Thus, Ireland as a member of the EMU faces increased cost of adjustment to asymmetric macroeconomic shocks.     

Real Exchange Rate Variability: An Empirical Analysis of the Developing Countries Case

The purpose of this paper is to investigate the potential role of monetary and real factors in explaining real exchange rate variability in developing countries. For this purpose two indexes of real effective exchange rate variability that measure short-term and long-term variability were constructed for 30 countries. The results obtained, using a generalized least squares procedures on cross section data, indicate that real exchange rate variability has been affected both by real and monetary factors. In particular it was found that more unstable nominal exchange rate policies were reflected in higher real exchange rate instability in the short-run; more unstable domestic credit policies resulted in higher short-term real exchange rate variability; and more unstable external terms of trade also affected positively the degree of real exchange rate instability.

The Exchange Rate: A Shock Absorber or Source of Shocks in Turkey?

This study investigates the role of the exchange rate as shock-absorber as opposed to a source of its own shocks in Turkey during the period from 1990 to 2009 by employing a structural VAR framework with long-run and short-run restrictions. We find that the economic shocks have predominantly been asymmetric relative to one of the largest trading partner, the US. Our results provide evidence of the fact that while the major source of variability in exchange rates in the pre-2001 crisis period is mainly nominal shocks, a large proportion of the exchange rate variability can be attributed to supply and demand shocks in the post-2001 crisis period. This suggets that, rather than reacting to shocks to the foreign exchange market, such as shifts in risk premia, the exchange rate moves mainly in response to the real shocks during the post-2001 crisis period. Hence, there is a sizeable role for exchange rate stabilization during this period, absorbing those shocks and therefore requiring opposed monetary policy responses.     

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.     

Cross‐country asymmetries in monetary policy transmission: evidence from EMU members

This paper analyzes monetary policy asymmetries in EMU participating countries. In particular, we use a structural dynamic modelling approach to investigate asymmetric monetary transmission in Europe. Asymmetries are investigated in two different ways. First, we restrict the estimated structural models reflecting the monetary constraints each country faced during the EMS period. We obtain well‐behaved and comparable effects of monetary policy shocks. Second, efficiency frontiers for the selected EMU countries are estimated. In computing the optimal combinations of output gap and inflation volatility we use a weighted average of interest rate and exchange rate, i.e. the Monetary Condition Index (MCI), as a policy instrument. The impulse response analysis implemented with the MCI shows relatively small differences in the responses of the real economy to monetary policy shocks. Altogether the results suggest that, no matter which policy instrument is used, output gap and inflation respond to identical monetary shocks with a similar speed and movement, albeit with a different degree of effect.     

Relative price variability and inflation: The Italian evidence

Using Italian data from 1954 to 1983, it is found that relative price variability and inflation are positively correlated only during the 1970s and the early 1980s, when their relationship appears to be largely induced by movements in the oil price, rather than by aggregate demand shocks. This result is consistent with the findings of Fischer, 1981, Fischer, 1982 for the U.S. and Germany (although, in contrast to the evidence for these two countries, no relationship can be detected between unexpected inflation and relative price variability). Furthermore, the comparison between the three countries provides substantial support for the hypothesis — tentatively advanced by Fischer (1982) — that the correlation between relative price variability and inflation is enhanced by monetary accommodation of real shocks. There is also evidence that in Italy both variables have been considerably affected by exchange rate movements.     

Monetary Shocks and Real Exchange Rate Hysteresis: Evidence from the G-7 Countries

Long-run monetary neutrality specifies that nominal disturbances do not affect long-run real exchange rates. However, the "over depreciation" of the US dollar in the late 1980s, after its strong appreciation earlier in the decade, suggested to a number of observers that nominal disturbances alter long-run real exchange rates; that is, money supply shocks entail real exchange rate hysteresis. Using data from the G-7 countries and the post-1973 float, the paper measures the long-run effects of relative money supply disturbances on real US dollar exchange rates. Little evidence of hysteretic monetary policy effects is found.     

Why does monetary policy respond to the real exchange rate in small open economies? A Bayesian perspective

To estimate how monetary policy works in small open economies, we build a dynamic stochastic general equilibrium model that incorporates the basic features of these economies. We conclude that the monetary policy in a group of small open economies (including Australia, Chile, Colombia, Peru, and New Zealand) is rather similar to that observed in closed economies. Our results also indicate, however, that there are strong differences due to the shocks from the international financial markets (mainly risk premium shocks). These differences explain most of the variability of the real exchange rate, which has important reallocation effects in the short run. Our results are consistent with an old idea from the Mundell–Fleming model: namely, a real depreciation to confront a risk premium shock is expansive or procyclical, in contradiction to the predictions of the balance sheet effect, the J curve effect, and the introduction of working capital into RBC models. In line with this last result, we have strong evidence that only in one of the five countries analyzed in this study does not intervene the real exchange rate, the case of New Zealand.     

A re-examination of the impacts of macroeconomic and financial shocks on real exchange rate fluctuation: evidence from G7 and Asian countries

ABSTRACT

This paper aims to investigate the sources of real exchange rate fluctuation by utilizing sign restrictions in structural vector autoregressive (SVAR) method. Under an agnostic identification scheme, the empirical results show that the delayed overshooting puzzle still exists in response to monetary shock even if price puzzle is ruled out by construction. In contrast, all countries experience a significant initial real depreciation, and then gradually appreciate in response to currency risk premium (CRP) shock. This finding is consistent with Dornbusch’s overshooting model. In addition, I examine the importance of investors’ expectations in determining the short-term variations in the real exchange rate. The results indicate that the CRP and expectation shocks obviously outperformed the demand, supply and monetary shocks in terms of explaining the real exchange rate fluctuation.     

Rational expectations,market shocks,and the exchange rate

The world economy has been subjected to numerous real shocks in recent years. In addition, purchasing-power parity seems to have collapsed. Critics of the monetary approach to the exchange rate have been quick to draw attention to these facts. This paper extends the basic framework of the monetary approach so that it provides a useful tool for explaining the impact of real shocks on the exchange rate and so that it is compatible with the existence of significant deviations from purchasing-power parity. The real shocks that are discussed include changes in commercial policy, the terms of trade, and productivity. It is demonstrated that real shocks influence the exchange rate through two distinct channels—a real-income channel and a deviations from purchasing-power-parity channel.     

Has Australia's floating exchange rate regime been optimal?

This paper develops a straightforward theoretical framework for evaluating exchange rate regime choice for small economies. It proposes that a floating exchange rate minimises national income and employment variation when real macroeconomic shocks predominate, whereas a pegged exchange rate achieves this goal should monetary shocks predominate. It then shows econometrically that, in the case of Australia, a floating exchange rate best suited the economy for the period 1985 to 2010, because real shocks were more significant than monetary shocks. Moreover, consistent with the theory, further results showing that a stronger (weaker) exchange rate correlated with positive (negative) deviations from trend GDP affirm that a floating exchange rate regime was optimal for Australia over this time.     

Real exchange rate dynamics: Relative importance of Taylor‐rule fundamentals,monetary policy shocks,and risk‐premium shocks

We first show that the solution to the real exchange rate under the Taylor rule with interest rate smoothing can have two alternative representations—one based on a first‐order difference equation and the other based on a second‐order difference equation. Then, by comparing error terms from these two alternative representations and analyzing their second moments, we evaluate the relative importance of Taylor‐rule fundamentals, monetary policy shocks, and risk‐premium shocks in the dynamics of the real exchange rate. Empirical results suggest that the risk‐premium shock is the largest contributor to real exchange rate movements for all the countries examined, with the Taylor‐rule fundamentals and monetary policy shocks playing a limited role. These results are robust to various alternative sets of parameter values considered for the Taylor rule with interest rate smoothing.     

Is There a Trade‐Off Between Inflation Variability and Output‐Gap Variability in the EMU Countries?

This paper examines the performance of monetary policy in eleven EMU countries for the whole period of the EMS. This is based on the trade‐off between inflation variability and output‐gap variability. To this end, we examine whether the introduction of an implicit inflation targeting by the EMU member countries after the Maastricht Treaty, changed the trade‐off between inflation variability and output‐gap variability. We employ a stochastic volatility model for two sub‐periods of the EMS (i.e. before and after the Maastricht Treaty). We find that the trade‐off varies amongst EMU countries. The implication of these findings is that there are asymmetries in the euro area, due to different economic structures among the member countries of the EMU.     

Insulation properties of separating exchange markets

Insulation properties play an important role for countries in favour of separating rates for separating transactions. Such properties insulate the open economy from monetary and real shocks, of domestic and foreign origins. Through theoretical and numerical analyses, we find that in a unified flexible exchange rate system, portfolio holders' expectations drive the price adjustment, leading to expectations of exchange rate changes. In separating exchange markets, the financial rate reflects the instability of portfolio holders' expectations and capital flows; however, the real exchange rate and hence the macroeconomy is stable. Uncertainty of shocks ceases to affect the real sector of the economy.     

Monetary Shocks and Real Exchange Rate Dynamics: a Reappraisal

This paper proposes a two‐country general‐equilibrium model incorporating a tradable sector with pricing‐to‐market as well as a nontradable sector. In that case, real exchange rate fluctuations arise from two sources: changes in the relative price of traded goods, that exemplify deviations from the law of one price, and movements in the relative price of traded to nontraded goods across countries. Our framework sheds light on the propagation mechanisms through which monetary shocks affect the real exchange rate. More specifically, the two components respond in opposite directions to monetary disturbances, which is consistent with data. Besides, the introduction of nontraded goods does not alter the predictive power of monetary shocks because the presence of nontraded goods magnifies the response of the deviation from the law of one price.     

Optimal exchange rate policy for a small oil-exporting country: A dynamic general equilibrium perspective

This paper examines the choice of optimal exchange rate regime for an oil-exporting small open economy using a welfare-based model. The paper extends the standard New Keynesian Small Open Economy model to include three countries: a small oil-exporting country and two large foreign countries. The model also features three sectors: traded, non-traded, and primary-commodity (crude-oil). The sources of uncertainty are random monetary (demand), productivity (real), and real oil price (supply) shocks. Despite the absence of a non-oil traded sector in this primary-commodity economy, the welfare analysis suggests that flexible exchange rate regimes can reduce external shocks and consumption volatility given certain caveats about pricing-schemes. The analysis also suggests that a basket peg is more welfare-improving than a unilateral peg, as higher volatility of the anchor currency reduces consumer welfare.     

Monetary Policy in the Open Economy Revisited: Price Setting and Exchange-Rate Flexibility

This paper develops a welfare-based model of monetary policy in an open economy. We examine the optimal monetary policy under commitment, focusing on the nature of price adjustment in determining policy. We investigate the implications of these policies for exchange-rate flexibility. The traditional approach maintains that exchange-rate flexibility is desirable in the presence of real country-specific shocks that require adjustment in relative prices. However, in the light of empirical evidence on nominal price response to exchange-rate changes—specifically, that there appears to be a large degree of local-currency pricing (LCP) in industrialized countries—the expenditure-switching role played by nominal exchange rates may be exaggerated in the traditional literature. In the presence of LCP, we find that the optimal monetary policy leads to a fixed exchange rate, even in the presence of country-specific shocks. This is true whether monetary policy is chosen cooperatively or non-cooperatively among countries.     

Monetary Policy in Russia: Identifying exchange rate shocks

Russian monetary policy has failed persistently to achieve sustained low inflation, both in absolute terms and relative to the peer group of countries similarly exiting from Soviet-style central planning. This paper explores the reasons for this state of affairs by analysing the kind of monetary policy that has been pursued by the central bank during the period 1995 to 2009. Our contribution is to search for a possible transmission channel between the real interest rate, inflation rate, exchange rate, output growth and foreign reserve growth, after having controlled for the effect of oil price inflation. Using a vector autoregressive model in error-correction form and using sign restrictions methodology, we show that the monetary authorities’ failure to abate double-digit inflation appears to be driven by the policy of exchange rate targeting, as reflected in our identified exchange rate shocks.     

Evidence on the sectoral monetary transmission process under a fixed exchange rate regime

Traditional macroeconomic models suggest that monetary policy changes are largely ineffective in fixed exchange rate economies. However, Edwards and Végh (1997) present a model that shows this might not be the case, as a tightening in monetary policy raises financial costs faced by firms and therefore lowers real wages and, by extension, consumption. This paper empirically tests this hypothesis using data on a country with one of the longest running fixed exchange rate regimes (1975–present). The results of the study confirm the theoretical predictions of Edwards and Végh, but they also show that the propagation of nominal shocks in fixed exchange rate systems is comparatively slower than in countries with a more flexible exchange rate regime.
