Exchange rate determination: Empirical evidence for the Greek drachma

We examine the monetary approach to the exchange rate from several perspectives, using monthly data on five Greek bilateral exchange rates. Using the Johansen multivariate cointegration technique we demonstrate that the monetary model is validate as a long-run relationship. Moreover, upon imposing the long-run monetary model restrictions we find that the proportionality of the exchange rate to relative monetary aggregates is accepted for the bilateral exchange rate of the Greek drachma with respect to the US dollar, the deutschemark, the pound sterling, the French franc and the Italian lira. Finally, using the Hansen-Johansen (1993) testing procedure, we reject the hypothesis of sample independency of the dimension of the cointegration space in all cases, apart from the German one, but we accept the hypothesis that the estimated coefficients do not display instabilities in recursive estimations.     

HAZARDS IN IMPLEMENTING A MONETARY CONDITIONS INDEX

Some recent studies have suggested constructing a Monetary Conditions Index (or MCI) to serve as an indicator of monetary policy stance. The central banks of Canada, Sweden and Norway all construct an MCI and (to varying degrees) use it in conducting monetary policy. Empirically, an MCI is calculated as the weighted sum of changes in a short-term interest rate and the exchange rate relative to values in a baseline year. The weights aim to reflect these variables’ effects on longer-term focuses of policy — economic activity and inflation. This paper derives analytical and empirical properties of MCIs in an attempt to ascertain their usefulness in monetary policy. An MCI assumes an underlying model relating economic activity and inflation to the variables in the MCI. Several issues arise for that model, including its empirical constancy, cointegration, exogeneity, dynamics and potential omitted variables. Because of its structure, the model is unlikely to be constant or to have strongly exogenous variables, yet constancy and exogeneity are critical for the usefulness of an MCI. Empirical analyses of Canadian, Swedish and Norwegian MCIs confirm such difficulties. Thus, the value of an MCI for conduct of economic policy is in doubt.     

Cross-section dependence and the monetary exchange rate model – A panel analysis

This paper tackles the issue of cross-section dependence for the monetary exchange rate model in the presence of unobserved common factors using panel data from 1973 until 2007 for 19 OECD countries. Applying a principal component analysis we distinguish between common factors and idiosyncratic components and determine whether non-stationarity stems from international or national stochastic trends. We find evidence that the common factors are I(1) while the idiosyncratic components are I(0). This finding indicates that cross-member cointegration exists and non-stationarity in exchange rates and fundamentals is mainly driven by common international trends. We find evidence that the common factors of the exchange rates and fundamentals are cointegrated. In addition, the estimated long-run coefficients of this common international relationship are in line with the suggestions of the monetary model with respect to income and money.     

Money stock targeting and money supply: A closer examination of the data

In a recent paper Mercenier and Sekkat (1988) use a linear-quadratic model to examine the willingness of a monetary authority in a small open economy to target its exchange rate. Based on their empirical results, the authors conclude that the Bank of Canada has displayed a willingness to use the money supply to target the Canada—US exchange rate. We re-examine their empirical results using a different estimation approach and with different assumptions about the forcing process of the exogeneous variables. We also extend the sample period to include more recent observations. While we find some weak evidence to support their conclusion, the results, in general, suggest that a linear-quadratic model may not be a particularly useful representation of the assumed exchange rate targeting by a monetary authority.     

Polish Stabilization: What can we learn from the I(2) Cointegration Analysis?

This paper investigates an array of nominal systems for the Polish economy, of domestic price level, import prices, exchange rates, money stock, nominal wages, and real output, and conducts I(1) and I(2) cointegration analyses. Post-stabilization monthly data are used, 1991:5–1999:12.A test for the presence of a price-wage spiral is performed, and the stabilization package is compared to its realization. The long-run homogeneity hypothesis, the impact of monetary and incomes policies, and of external sector variables on long and medium run price development are studied. It is found that in Poland, contrary to some earlier studies, the external sector is not important for the long run price development. On the contrary, very strong evidence is found of the cost-push inflation.     

Monetary policy in a small open economy with fixed exchange rate: The case of Macedonia

This paper empirically applies the New Keynesian model for monetary policy analysis in a small open economy with a fixed exchange rate. Official reserves are included in the interest rate rule to account for the constraint that these impose on monetary policy when the exchange rate is fixed. Also, the foreign interest rate is included in order to reflect the necessity of following the foreign monetary policy. The model is applied to Macedonian data from the period 1997 to 2011. In general, results indicate that monetary policy has been focused on domestic objectives during this period, despite the fixed currency. In addition, there seem to have been significant differences in the conduct of the monetary policy in the first and second half of this period. The response to inflation has been more aggressive in the earlier period, at a time when reserves appear less important, while the output gap is found to be important only in the latter period, possibly due to the stronger monetary policy transmission. Finally, results indicate that the monetary policy has likely moved from adaptive in the first period to rational in the second period.     

Nonlinearities in exchange rate determination in a small open economy: Some evidence for Canada

We analyze bilateral Canadian-US dollar exchange rate movements within a Markov switching framework with two states, one in which the exchange rate is determined by the monetary model, and the other in which its behavior follows the predictions of a Taylor rule exchange rate model. There are a number of regime switches throughout the estimation period 1991:2–2008:12 which we can each relate to particular changes in Canadian monetary policy. These results imply that an active monetary policy stance may account for nonlinearities in the exchange rate-fundamentals nexus. The strong evidence of nonlinearities also confirms the notion that exchange rate movements cannot be explained exclusively in terms of any one particular exchange rate model.     

Unit root and cointegration tests on the efficiency and biasedness of forward exchange rates

This paper analyzes the stationarity of spot and forward exchange rates by testing for the presence of unit roots in the autoregressive process of the exchange rate time series. The results of the unit root and cointegration tests for forward exchange rates of six major currencies are inconsistent with earlier studies by others that found the existence of unit roots but the absence of cointegration. Our results show that realized spot rates are cointegrated with past forward rates. Both Dickey-Fuller and Augmented Dickey-Fuller tests affirm the unbiased forward rate hypothesis for 30- and 90-day forward rates. The Augmented Dickey-Fuller tests on the longer term forward rate, however, reveal the existence of cointegration that leads to the rejection of the hypothesis.     

Mexico’s balance of payments and exchange rates: a cointegration analysis

Mexico’s recurrent economic crises have cast serious doubts on the existence of a long-run relationship between the country’s balance-of-payments and exchange rates. In this paper, cointegration and vector autoregression techniques are applied to Mexico’s data covering the period 1971 through 1988. Despite the presence of nonstationarity, the statistical analysis supports a long-run relationship between changes in international reserves and the exchange rate and changes in domestic credit. Further multivariate Granger causality tests, together with innovation accounting, indicate that Mexico’s monetary authorities adjust domestic assets to sterilize balance-of-payments deficits in a futile attempt to control its monetary policy.     

Do the black market and the official exchange rates converge in the long run?

Establishing cointegration and long-run convergence between the official and the black market exchange rates is a way of testing foreign exchange market efficiency. Earlier research employed the Engle-Granger or Johansen method to test for cointegration between the two rates. Since either method requires each rate to be non-stationary, exchange rates that did not possess this property had to be excluded from analysis. However, with the introduction of the bounds testing approach to cointegration, no exchange rate needs to be excluded since this relatively new technique does not require pre-unit root testing. This paper employs monthly data from 27 developing countries and the bounds testing approach to cointegration by Pesaran et al. (2001) to show that in 22 out of 27 countries, not only are the two rates cointegrated but in all countries the black market exchange rate causes the official rate to adjust and converge toward the black market rate in the long run.     

Monetary policy rules for convergence to the Euro

This paper investigates the applicability of open-economy convergence-consistent instrument rules for monetary policies in the economies undergoing monetary convergence to a common currency area. The proposed policy rule is forward-looking, consistent with a monetary framework based on inflation-targeting containing input variables that are relative to the corresponding variables in the common currency area. Robust forms of the policy rule are tested empirically for three inflation-targeting countries converging to the euro, i.e. the Czech Republic, Poland and Hungary. Empirical tests imply systemic differences in monetary policies among these euro-candidates. The Czech monetary policy seemingly follows the rule prescribed by our model. Both the Czech and the Polish central bank interest rate policies respond predominantly to changes in the inflation gap, while the Hungarian responds mainly to the exchange rate gap. In all three cases, changes in the eurozone short-term interest rates strongly drive adjustments in the central banks’ reference interest rates.     

Interest rate pass-through in South East Europe: An empirical analysis

This paper investigates the effectiveness of the interest rate channel in three small open economies with rigid exchange rate regimes in South East Europe – Bulgaria, Croatia and Macedonia – during the period 2000–2010. Specifically, we examine the size and speed of adjustment of bank lending rates to the changes in money market rates by employing various cointegration methods. In addition, we assess the stability of interest rate passthrough during the transition period, including the recent economic crisis. The results reveal the existence of a cointegrating relationship among some of the interest rates. We find that the long-run pass-through is far from complete with the exception of Macedonia. The shortrun adjustment of lending rates is also low and sluggish, implying that the domestic monetary policy may have a limited impact on the interest rate channel. Finally, the econometric investigation provides mixed evidence on the stability of the interest rate pass-through. Therefore, the overall findings of the paper support the view that in small open economies with rigid exchange rates the effectiveness of domestic monetary policy through the interest rate channel is quite limited.     

Forecasting the exchange rate using nonlinear Taylor rule based models

This research utilises a non-linear Smooth Transition Regression (STR) approach to modelling and forecasting the exchange rate, based on the Taylor rule model of exchange rate determination. The separate literatures on exchange rate models and the Taylor rule have already shown that the non-linear specification can outperform the equivalent linear one. In addition the Taylor rule based exchange rate model used here has been augmented with a wealth effect to reflect the increasing importance of the asset markets in monetary policy. Using STR models, the results offer evidence of non-linearity in the variables used and that the interest rate differential is the most appropriate transition variable. We conduct the conventional out-of-sample forecasting performance test, which indicates that the non-linear models outperform their linear equivalents as well as the non-linear UIP model and random walk.     

Market efficiency and cointegration: Some evidence in Pacific-Basin black exchange markets

This paper investigates the efficiency of the black exchange markets in Indonesia, Malaysia, the Philippines, South Korea, Taiwan, and Thailand. The study applies unit root and cointegration tests to examine black exchange market efficiency of Pacific-Basin countries. The generating process of black exchange rates appears to be a random walk. This is consistent with Gupta (1981) and other foreign exchange rate unit root test studies. Johansen cointegration tests are performed for these black exchange markets together with Japan and Singapore. The results suggest that there is at least one unit root among the black market exchange rates. Hence, black exchange markets are not collectively efficient.     

Internal and external transmissions of monetary and fiscal policies in the EMU

With the introduction of Economic and Monetary Union (EMU), the sovereignty of national monetary institutions has been replaced by a common monetary institution, the European Central Bank (ECB) and national currencies have been replaced by a common currency, the euro. EMU therefore implies the loss of national monetary policy autonomy and internal exchange rate flexibility inside the EMU area. However, external exchange rate adjustment, i.e. adjustment of the euro exchange rate, remains a feasible adjustment mechanism. This paper analyses how internal and external exchange rate flexibility affect macroeconomic adjustment in EMU and non-EMU countries. To do so, a model is constructed in which three countries interact: two countries that decide to form a monetary union and a third country that does not participate in the monetary union. Numerical simulations of a representative example are used to characterise the adjustment dynamics induced by monetary and fiscal policies before and after the start of the EMU.     

Managed Floating as a Monetary Policy Strategy

Although there seems to be a broad consensus among economists that purely floating or completely fixed exchange rates (the so-called corner solutions) are the only viable alternatives of exchange rate management, many countries do not behave according to this paradigm and adopt a strategy within the broad spectrum of exchange rate regimes that is limited by the two corner solutions. Many of these intermediate regimes are characterized by significant foreign exchange market interventions and a certain degree of exchange rate flexibility with non-preannounced exchange rate targets. While academic research in this area usually concentrates on some specific aspects of intermediate regimes (such as the effectiveness of interventions or institutional aspects), managed floating has rarely been analyzed as a comprehensive monetary policy strategy. In this paper, we present a monetary policy framework in which central banks simultaneously use the exchange rate and the interest rate as operating targets of monetary policy. We explain the mechanics of foreign exchange market interventions and sterilization and we explain why a central bank has an interest of controlling simultaneously the two operating targets. We derive the monetary policy rules for the two operating targets from a simple open economy macro model in which the uncovered interest parity condition and the monetary conditions index play a central role.     

An input–output model of exchange-rate pass-through

The impact of the exchange rate on price formation is often debated through a mechanism called the exchange-rate pass-through. Studies of the pass-through generally rely on econometric analysis implemented on time series data. This study examines pass-through to the domestic price level through an input–output model. The proposed model is implemented on a sample of countries, and a number of different variables connected to the pass-through are examined. A comparison across countries and sectors highlights the importance of the construction sector in price formation. National income is negatively related to the pass-through. A high dependence on intermediate imports implies higher pass-through. Price level volatility and pass-through are positively related; whereas a country’s monetary policy stance has no apparent effect. The effect of exchange-rate volatility is unclear; it is negative for the real effective exchange rate, the connection is very weak in the case of the nominal exchange rate.

Evaluating New‐Keynesian Models of a Small Open Economy*

We suggest a strategy to evaluate members of a class of New‐Keynesian models of a small open economy. As an example, we estimate a modified version of the model in Svensson [Journal of International Economics (2000) Vol. 50, pp. 155–183] and compare its impulse response and variance decomposition functions with those a structural vector autoregression (VAR) model. The focus is on responses to foreign rather than to domestic shocks, which facilitates identification. Some results are that US shocks account for large shares of the variance of Canadian variables, that little of this influence is due to real exchange rate movements, and that Canadian monetary policy is not adequately described by a Taylor rule.
