Safe‐haven currency: An empirical identification

This paper attempts to empirically identify strong safe havens among six currencies: the Swiss franc, Japanese yen, British pound, euro, Canadian dollar and Norwegian krone. Using Markov regime‐switching vector autoregressive models, we test whether the currencies are negatively related to risky assets and whether the negative relation is stronger in times of crisis than in times of growth. We find that (1) the Swiss franc and Japanese yen qualify as strong safe havens, and (2) the other currencies qualify as “equity‐like” or risky currencies.     

Tail behaviour of the euro

This paper empirically analyses risk in the euro relative to other currencies. Comparisons are made between a subperiod encompassing the final transitional stage to full monetary union with a subperiod prior to this. Stability in the face of speculative attack is examined using Extreme Value Theory to obtain estimates of tail exchange rate changes. The findings are encouraging. The euro's common risk measures do not deviate substantially from other currencies. Also, the euro is stable in the face of speculative pressure. For example, the findings consistently show the euro being less risky than the yen, and having similar inherent risk to the Deutsche mark, the currency that it is essentially replacing.     

The purchasing power parity of Southeast Asian currencies: A time-varying coefficient approach

The economies of Southeast Asia have undergone several structural changes, including the Asian currency crisis, during the post-Bretton Woods era. We use a time-varying coefficient cointegration model to test for purchasing power parity (PPP) of Southeast Asian currencies and to track changes in purchasing power relationships over time. The main empirical findings are as follows. First, the stability of the relationship between exchange rates and price differentials is strongly rejected. Second, a major structural change occurs at the outbreak of the Asian currency crisis in 1997. Third, when the cointegration vector is allowed to vary with time, we find evidence of a cointegration relationship for four countries in terms of the US dollar and for four countries in terms of the Japanese yen. Therefore, it seems unlikely that Southeast Asian currencies form a “yen bloc.”     

The Real Yen Exchange Rate and Japanese Productivity Growth

This study investigates the time-series properties of five real yen exchange rates by testing for stationarity in the context of a single structural shift. It finds that all but one of the series are stationary in conjunction with a trend- or mean-break in the late 1950s or early 1970s. By comparison, most real rates for five other industrialized countries are stationary around a constant mean. These findings suggest that the behavior of the real yen exchange rate is unique among the six currencies in the sample, a difference that may originate in the exceptional productivity performance of the Japanese traded-goods sector.     

Four harmonic cycles explain and predict commodity currencies' wide long term fluctuations

In theory and practice, it is difficult to accept a particular model of explanation and forecasting of exchange currencies as the literature review reveals. However, the currencies that are called commodity currencies, such as the Australian dollar are heavily influenced by commodity prices cycles, and hence they might be easier to analyze and predict. We investigate the possibility that the Australian dollar is primarily determined by a handful of harmonic cycles which in turn are based not only on commodity prices cycles but also on commodity production cycles and in general on economic cycles. In this way we can get a very good fit of the relevant data and good out-of-sample forecasts. We cross check these results by referring to the main issues involved, such as fundamentals, short and long cycles, and so on. In addition, our analysis, forecasting ability, and conclusions still hold for three more commodity currencies examined here: New Zealand's dollar, Canada's dollar, and Norway's krone.     

Asymmetry effects of exchange rate changes on domestic production in Japan

Previous studies that assessed the effects of currency depreciation on the domestic production of Japan did not find any significant long-run effects. Using the linear ARDL approach we first confirm previous findings. We then argue and show that failure to find any significant link between the value of the yen and Japanese domestic production is due to assuming a linear adjustment mechanism or symmetric effects of exchange rate changes. Once we use the nonlinear ARDL approach we show that indeed exchange rate changes do have asymmetric effects on domestic production in Japan. Not only we observe adjustment asymmetry, but also short-run asymmetry that lasts into the long run. In the long run while strong yen seems to hurt domestic production in Japan, weak yen seems to have no effect.     

Manufacturing and the Trade Balance

When the world shifted to the regime of flexible exchange rates after 1970, economists expected that large trade imbalances would soon disappear. Instead, such imbalances not only persisted but soared in the 1980s and 1990s, in spite of significant changes in important currencies such as the yen, the mark and the dollar. This paper reports that manufacturing importers tend to suffer trade deficits whereas exporters of manufacturing products tend to enjoy trade surpluses. The reason lies in the higher rates of productivity growth experienced by exporters of manufactures.     

Risk premia in forward foreign exchange rates: a comparison of signal extraction and regression methods

We investigate possible presence of time-varying risk premia in forward pound, yen, and Euro monthly exchange rates versus the US dollar over the last two decades. We study this issue using regression techniques and separately using a signal plus noise model. Our models account for time-varying volatility and non-normality in the observed series. Our regression model rejects the hypothesis that the forward rate is an unbiased predictor of future spot exchange rate, indicating the existence of time-varying risk premium under rational expectations. Our signal plus noise model reveals a time-varying risk premium component in yen and Euro. The same model provides evidence for the presence of risk premium in pound over a shorter sample period, though not over the entire sample. We conclude that risk premia exist, although we may fail to detect these for some currencies over specific time periods.     

Exchange-rate pass-through in Japanese export pricing

Two recent aggregative studies claim to demonstrate that Japanese exporters absorb a proportion of exchange-rate changes in their profit margins; but the estimates of this proportion are dramatically different. This study accounts for the discrepancy, and shows that neither estimate is credible. These results identify incomplete pass-through, conditional on costs, as a transitory consequence of export pricing in currencies other than yen. The only long-run effect of the exchange rate on yen-dominated export prices operates through imported materials prices.     

SYNCHRONIZATION OF ECONOMIC SHOCKS BETWEEN GULF COOPERATION COUNCIL AND UNITED STATES,EUROPE, JAPAN,AND OIL MARKET: CHOICE OF EXCHANGE RATE REGIME†

Using a structural vector autoregression (SVAR) with block exogeneity, this study examines the impacts of external shocks originating from the United States, the European Union, Japan, and the oil market as well as those of the regional shocks, on the oil‐rich countries of the Gulf Cooperation Council (GCC), viewed as a prospective monetary union. It takes into account the implications of the shock impacts for selecting an appropriate common exchange rate arrangement. The SVAR variance decomposition and impulse response analyses strongly underscore the relative impacts of the global shocks over the regional ones. The findings imply that the world's two major currencies, the U.S. dollar and the euro, should figure highly in a GCC's common basket of currencies. Accordingly, a transitional movement to a more flexible exchange rate arrangement such as a basket peg may be desirable for these trade‐dependent economies in the long run, as is argued in the optimal currency literature for developing countries.

Assessing the Economic Preconditions for a Yen Bloc

Stabilising Asia-Pacific exchange rates by establishing a system of pegs, bands or target zones around the Japanese yen requires the compromise of domestic policy autonomy. The cost of doing so is least when members reaction to economic shocks are symmetric. This study considers which currencies meet this necessary precondition. To assess regional disturbance symmetry the Blanchard and Quah (1989) procedure is employed to distinguish temporary from permanent shocks for paired aggregate output and price time-series. Disturbance correlations between Japan and other Asia-Pacific nations are calculated. Supply-side disturbance correlations are relatively weak and suggest the economic preconditions for a yen bloc are not in place.     

EXCHANGE RATE,EXPECTED PROFIT AND CAPITAL STOCK ADJUSTMENT: JAPANESE EXPERIENCE

This paper empirically investigates the impact of exchange rate shocks on capital stock adjustment in the Japanese industry. An intertemporal optimization model is developed, in which an individual corporation in an open economy adjusts its capital stock according to Tobin's q. By explicitly considering the marginal q, the transmission mechanism from real exchange rate shocks to investment dynamics is examined based on the Vector Autoregressive model. Empirical evidence suggests that the depreciation of the Japanese yen increases the expected profitability of the firm and stimulates investment, especially in the machinery sector.     

Testing for random walk in euro exchange rates using the subsampling approach

This study utilizes variance ratio tests based on the subsampling approach to test the behaviour of euro-based exchange rates markets. Results are mixed, although the random walk behaviour is dominant among the three major currencies namely the Japanese yen, the US dollar and the British pound.     

Smooth structural breaks and the stationarity of the yen real exchange rates

This article examines and solves an interesting paradox in the literature that the tests for purchasing power parity (PPP) based on the yen real exchange rates (RERs) refute the PPP hypothesis more often than those with other major currency-based RERs, and the evidence is sensitive to the sample period used. Using a new empirical methodology accounting for both nonlinearity and multiple smooth temporary breaks in the data, we show that the puzzling finding is due to the failure to take into account the long but temporary large rise and fall in the yen RERs. The results illustrate that the yen RERs in the post-Bretton Woods period are likely mean reverting with linear or nonlinear adjustment toward large, long swing type of infrequent smooth temporary changes around constant equilibrium values, supporting the validity of PPP and resolving the paradox.     

Foreign exchange market interventions and the $–¥ exchange rate in the long run

This article examines whether foreign exchange market interventions conducted by the Bank of Japan are important for the dollar–yen exchange rate in the long run. We rely on a re-examination of the empirical performance of a monetary exchange rate model. This is basically not a new topic; however, we focus on two new questions. First, does the consideration of periods of massive interventions in the foreign exchange market uncover a potential long-run relationship between the exchange rate and its fundamentals? Second, do Forex interventions support the adjustment towards a long-run equilibrium value? Our results suggest that taking periods of interventions into account within a monetary model does improve the goodness of fit of an identified long-run relationship to a significant degree. Furthermore, Forex interventions increase the speed of adjustment towards long-run equilibrium in some periods, particularly in periods of coordinated forex interventions. Our results indicate that only coordinated interventions seem to stabilize the dollar–yen exchange rate in a long-run perspective.

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.     

Money demand instability and real exchange rate persistence in the monetary model of USD–JPY exchange rate

This paper proposes a hybrid monetary model of the dollar–yen exchange rate that takes into account factors affecting the conventional monetary model's building blocks. In particular, the hybrid monetary model is based on the incorporation of real stock prices to enhance money demand stability and also, productivity differential, relative government spending, and real oil price to explain real exchange rate persistence. By using quarterly data over a period of high international capital mobility and volatility (1980:01–2009:04), the results show that the proposed hybrid model provides a coherent long-run relation to explain the dollar–yen exchange rate as opposed to the conventional monetary model.     

Interest expectations and exchange rates news

Using a new survey data set ofmatched exchange rate and interest rate expectations for eight currencies relative to the German mark, we examine empirically the relationship between exchange rate returns, news and risk premia. News on interest differentials enters significantly in equations for the difference between the spot rate and the lagged forward rate for the British pound, Japanese yen, Spanish peseta and the US dollar. An unexpected rise in the interest rate differential tends to strengthen the domestic exchange rate. For each of these currencies, we also find significant effects of our ex-ante measure of the risk premium. In addition, we investigate the effect of lagged interest rate differentials as proxy for the risk premium and find that they do not capture time-varying risk premia as is widely suggested in the literature, but probably capture a peso-problem, learning about a policy change, a market-inefficiency or a combination of these factors.     

Estimating an equilibrium exchange rate for the dollar and other key currencies

In this paper, we adapt the concept of fundamental equilibrium exchange rates ‘FEER’ in a complete model approach. We use it to determine the likely paths of the Dollar and other key currencies. The FEER is the (real) exchange rate that is consistent with internal balance and sustainable external balances. Here we examine the composition of a Dollar adjustment and hence the extent to which a FEER (for the US) depends on factors or rigidities elsewhere in the world, as well as at home. We find, the US still needs to accept an adjustment in her real exchange rate if the increase in her foreign liabilities is to come to an end. However, counterpart adjustments also have to be made in Canada, Mexico, and some Asian economies if this policy is to be successful. We also show that productivity growth differentials may act as a substitute for depreciation, and this provides an explanation for the failure of the dollar to depreciate in the 1990s.
