The failure of the monetary exchange rate model for the Canadian-U.S. dollar

In this paper the validity of the monetary exchange rate model in the long run for the Canadian-U.S. dollar exchange rate is examined. The primary test employed is the Johansen (1991) and Johansen and Juselius (1990) cointegration technique. The effects of dummy variables and lag specification on the statistical inference are considered, and Monte Carlo simulations based on the estimated parameters are employed. Despite the use of the longest data set yet for the Canadian case, no evidence is found in favour of the monetary exchange rate model using the Johansen procedures. This result is confirmed by several other cointegration procedures. JEL Classification: F31; F41
La faillite du modèle monétaire du taux de change pour les dollars canadien et américain. Ce mémoire examine le modèle monétaire du taux de change pour savoir s'il est validé par l'expérience canado-américaine en longue période. Le test principal utilisé est la technique de cointégration de Johansen (1991) et Johansen et Juselius (1990). Les effets des variables fictives et de la spécification de la structure de délais sur l'inférence statistique sont considérés, et on utilise des simulations de Monte Carlo fondées sur les paramètres calibrés. Malgré le fait qu'on fait appel à la plus longue série chronologique utilisée dans ce type d'analyse à ce jour, on ne trouve aucun support du modèle monétaire du taux de change en utilisant les procédures de Johansen. Ce résultat est confirmé par l'utilisation de plusieurs autres procédures de cointégration.     

Autoregressive conditional durations: An application to the Surinamese dollar versus the US dollar exchange rate

The parallel market nominal exchange rate of the United States dollar vis-à-vis the Surinamese dollar (USD/SRD) exhibited periods of severe volatility which were often followed by episodes of stability, usually at a cost of sharp depreciations. This study seeks to model this exchange rate using autoregressive conditional duration models. These models are suitable for modelling events occurring with irregular intervals. Exchange rates in developing countries have distinct features compared to exchange rates in countries with well-established and accessible financial markets. A key feature is that for these developing countries, exchange rates only occasionally experience jumps. Our findings suggest that past exchange rate changes appear to be a significant driver of future exchange rate jumps. Furthermore, our results show that money, international reserves, and commodity prices can explain jumps in the market USD/SRD exchange rate.     

Excess comovements between the euro/US dollar and pound sterling/US dollar exchange rates

ABSTRACT

The aim of this article is to discuss excess comovements of the euro/US dollar and pound sterling/US dollar exchange rates, i.e. we look for comovements of exchange rates which are stronger than implied by the fundamentals. The results of the empirical analysis provide evidence that excess comovements exist for the two exchange rates. A long-run analysis of correlations can verify that a link exists between the correlation dynamics of exchange rates, relative inflation rates, long-term interest rates, economic sentiments and money supply. We find that common movements of money supply, prices and economic sentiments each play a major role in comovements of the exchange rates. From the investigation of the two exchange rates, we conclude that macroeconomic fundamentals can account for the comovement but that common non-fundamental factors also have major significance for the exchange rates.     

Panel cointegration and the monetary exchange rate model

This paper re-examines the validity of the monetary exchange rate model during the post-Bretton Woods era for 18 OECD countries. Our analysis simultaneously considers the presence of both cross-sectional dependence and multiple structural breaks, which have not received much attention in previous studies of the monetary model. The empirical results indicate that the monetary model emerges only when the presence of structural breaks and cross-country dependence has been taken into account. Evidence is also provided suggesting that the breaks in the monetary model can be derived from the underlying purchasing power parity relation.     

The Canadian border and the US dollar: The impact of exchange rate changes on US retailers

This paper provides a micro‐level investigation into the impact of changes in the US–Canada nominal exchange rate on retailers in US regions lying close to the US–Canada border. Using a large data set on product‐level retail prices and sales in the United States over a nine year period, we explore the links between changes in exchange rates, cross‐border travel and the price and quantity responses of US retailers. This allows us to assess the importance of geography and distance in affecting the pass‐through of exchange rate changes into prices and quantities at the level of the consumer. We develop a two‐stage theoretical model of cross‐border travel and industry equilibrium for retail sales at the border. Our empirical results accord well with the implications of the model.     

The failure of the monetary model of exchange rate determination

In this article, we test three popular versions of the monetary model (flexible price, forward-looking and real interest differential models) for the OECD member countries by applying Johansen cointegration technique. Based on country-by-country analysis, we conclude that monetary models do not provide the expected results. We reveal several shortcomings of the models and examine the building blocks of the fundamental version. Although researchers always blame the deviations from purchasing power parity as the reason for the failure of the monetary model, our analysis indicates that invalidity of Keynesian money demand function is also responsible for unfavourable results.     

A problem with estimating the short-run monetary exchange rate model

This paper shows that a composite moving average error is typically implied by a short-run monetary model of exchange rate. Thus, relying solely on the Durbin-Watson (DW) statistic as an indicator of serial correlation is inappropriate and may lead to inefficient coefficient estimates. We suggest that the time-series model technique of Box and Jenkins (1976) be used to identify an error model. The short-run monetary model of the exchange rate can then be estimated as a transfer function model by a maximum likelihood procedure.     

On the deviations from purchasing power parity: the case of the Ringgit effective exchange rate

The paper investigates the extent to which the Ringgit exchange rate converges on its purchasing power parity level in the long run, using the cointegration and variance ratio tests. The results indicate that shifts in the real exchange rate are dominated by permanent stochastic shocks which prevent it from reverting to its PPP base level. Further analysis indicates that low frequency movements in the relative price of tradable goods and the external terms of trade cannot explain the long-run swing in the real exchange rate.     

A short-run monetary model of exchange rate determination: Stability tests and forecasting

The paper develops a short-run econometric monetary model of exchange rate determination. The model assumes a conventional money demand function, markets which are linked by interest arbitrage, adaptive expectations formation, and parameters which are stable over time. One-period-ahead forecasts of the mark/pound rate generated by the model compare favorably with naive model forecasts using monthly data. Stability tests provided evidence of parameter instability in 1976 but correction for it did not improve forecasting accuracy. The inability of monetary models to forecast accurately may be due to the underlying model assumptions rather than parameter instability.     

The role of the exchange rate in Canadian monetary policy: evidence from a TVP-BVAR model

A time-varying parameters Bayesian structural vector autoregression (TVP-BVAR) model with stochastic volatility is employed to characterize the monetary policy stance of the Bank of Canada (BoC) in terms of an interest rate rule linking the policy rate to the output gap, inflation and the exchange rate. Using quarterly bilateral Canadian–US data, we find such an interest rate rule to have little explanatory power for the early part of our sample starting in the mid-1980s, but to become more suitable to explain interest rate dynamics from the mid-1990s onwards. Whereas the exchange rate turns out to be the major determinant of the policy rate in the 1980s, its importance declines throughout the 1990s and 2000s, although it continues to be influential even towards the end of the sample period ending in 2015Q2. We also find interest rate shocks to have become more effective in influencing the macroeconomy over time, indicating that the BoC has continually gained monetary policy credibility. We associate this development with the BoC successively de-emphasizing the role of the exchange rate in informing interest rate decisions, thereby alleviating the potential monetary policy conflict between targeting the exchange rate and maintaining the price stability goal.     

On the predictability of daytime and night-time yen/dollar exchange rates

This article first shows that the yen/dollar rate tended to appreciate in Japan daytime but to depreciate in Japan night-time in the 2000s. The result is very paradoxical because the asymmetry implies that the intra-daily yen/dollar rate had predictable stochastic trends in the 2000s. The article then investigates whether lagged dependent variables and various external shocks were responsible to the asymmetric feature. We find that once we control the effects of lagged dependent variables and external shocks, the daytime yen/dollar rate tended to appreciate when it had appreciated on the day before, while the night-time yen/dollar rate tended to depreciate when it had depreciated on the day before.     

Interaction between oil and US dollar exchange rate: nonlinear causality,time-varying influence and structural breaks in volatility

This article examines the nonlinear Granger causality and time-varying influence between crude oil prices and the US dollar (USD) exchange rate using the Hiemstra and Jones (HP) test, the Diks and Panchenko (DP) test and the time-varying parameter structural vector autoregression model. By applying the iterated cumulative sums of squares (ICSS) algorithm and the DCC-GARCH model, the effects of structural breaks in volatility of the two markets are also investigated. The empirical analysis indicates that, first, crude oil prices are the nonlinear Granger-cause of the USD exchange rate, but not vice versa. Second, the USD exchange rate exerts a stronger and more stable negative influence on crude oil prices in the short term, and the influence gradually weakens after 2012. Finally, ignoring structural breaks can increase the negative volatility correlation between the oil and USD exchange rate markets, which is particularly remarkable during the financial crisis.     

Asymmetric impact of monetary surprises on exchange rate

This paper examines the asymmetric response of exchange rate to monetary surprises. After controlling the type, direction and origin of the news as well as business cycle phase, a new asymmetry is found in the response of the exchange rate to news surprises. In specific, the US Dollar depreciates against major currencies as the response to the negative monetary surprises in the 2001 recession, while the Dollar appreciates responding to similar negative monetary surprises during the 2008 recession. The paper further explores possible causes and finds that time-varying status of the currency with higher financial returns may contribute to the new asymmetry.     

Dynamic forecasting of monetary exchange rate models: Evidence from cointegration

The Frenkel-Bilson and Dornbusch-Frankel monetary exchange rate models are used to estimate the out-of-sample forecasting performance for the U.S. dollar/Canadian dollar exchange rate. By using Johansen's multivariate cointegration, up to three cointegrating vectors were found between the exchange rate and macroeconomic fundamentals. This means that there is a long-run relationship between the exchange rate and economic fundamentals. Based on error correction models, two monetary models outperform the random walk model at the three-, six-, and 12-month forecasting horizons. Therefore, monetary exchange rate models are still useful in forecasting exchange rates.     

Does the Euro follow the German Mark? Evidence from the monetary model of the exchange rate

This paper investigates whether German or synthetic European pre-EMU data provides the appropriate empirical basis for evaluating Euro/Dollar exchange rate behavior. Monetary exchange rate equations are estimated for both data sets over the pre-EMU period, and out-of-sample forecasts are evaluated to assess their ability to explain the Euro/Dollar exchange rate from 1999 to 2004. While forecast accuracy tests confirm the usefulness of synthetic European data for Euro exchange rate analysis, forecasts based on the German pre-EMU experience cannot even beat a random walk. Our results indicate that the Euro does not simply follow the German Mark, but that it has its origins in the other pre-EMU currencies as well.     

The effects of Japanese foreign exchange market interventions on the yen/U.S. dollar exchange rate volatility

In previous empirical work, the link between the interventions of the Bank of Japan (BoJ) and exchange rate volatility has mainly been analyzed by using data on press reports of BoJ interventions. We use official intervention data for the period 1993–2000 that were released only recently by the BoJ. We find a positive link between the interventions of the BoJ and the volatility of the yen/U.S. dollar exchange rate. We also find that those BoJ interventions that were not reported in the financial press were positively correlated with exchange rate volatility.     

The exchange rate mechanism's role in the european monetary system

The European Community was established with the intent of reaching full economic, monetary, and political union among its member countries. The three elements of the European Monetary System—the Exchange Rate Mechanism, the European Currency Unit, and the European Monetary Fund—were designed to work together to achieve monetary integration among the member states. German reunification, as a result of the collapse of the Berlin Wall, played an important role in the failure of the Exchange Rate Mechanism. Many steps will need to be taken in order for the European community to obtain full economic and monetary union.
