Unanticipated money,output, and prices in the small economy

A macroeconomic model for an open economy experiencing both domestic and international monetary disturbances is given. Expectations are assumed to be rational. Particular attention is focused on the reduced form coefficients for unanticipated domestic and foreign monetary disturbances under alternative exchange rate regimes.     

COMPARATIVE ANALYSIS OF EXCHANGE RATE APPRECIATION AND AGGREGATE ECONOMIC ACTIVITY: THEORY AND EVIDENCE FROM MIDDLE EASTERN COUNTRIES

The paper examines the effects of exchange rate depreciation on real output and price in a sample of 11 developing countries in the Middle East. The theoretical model decomposes movements in the exchange rate into anticipated and unanticipated components. Unanticipated currency fluctuations determine aggregate demand through exports, imports, and the demand for domestic currency, and determine aggregate supply through the cost of imported intermediate goods. The evidence indicates that the supply channel attributed to anticipated exchange rate appreciation results in limited effects on output growth and price inflation. Consistent with theory's predictions, unanticipated appreciation of the exchange rate appears more significant with varying effects on output growth and price inflation across developing countries.     

The administered Bank rate and the Canada-U.S. spot exchange rate: 1975–1979

This paper analyzes, for the period 1975–1979, the announcement effect of the unanticipated Canadian administered Bank rate changes (the Bank rate is analogous to the discount rate in the U.S.) on the Canada-U.S. dollar spot exchange rate. Leading and/or lagged announcement effects are also investigated. By examining the behaviour of the residuals, on and surrounding the announced Bank rate changes, derived from an autoregressive equation of the daily changes (4:30 p.m. to noon the following day) in the logarithm of the spot $ Canadian/$ U.S. rate the evidence seems to indicate, on the average, a significant adjustment (appreciation of the Canadian dollar for Bank rate increases and depreciation for Bank rate decreases) of the exchange rate on the day of the effective unanticipated administered Bank rate changes regardless of the assumptions made with respect to the probability distribution of the residuals — whether it be normal, symmetric stable with a characteristic exponent of 1.8, or nonparametric.     

The Impact of Monetary Surprises on Australian Financial Futures Markets: An Insight into Cash Rate Target Announcements

This paper investigates the impact of unanticipated Australian monetary policy changes on AUD/USD exchange rate futures, and 3‐year and 10‐year Australian Treasury bond futures, during the period from January 1997 to April 2010. Our study contributes to the literature by using both the 30‐day and the 90‐day bank accepted bill (BAB) rates to disentangle the unexpected surprise component of monetary policy changes from overall cash rate target changes in the Australian money market, and by concurrently modelling the effects of monetary surprises and other key macroeconomic announcements in Australia. The empirical results suggest that the 30‐day BAB rate is the best proxy for the expected monetary policy actions. We find that the effect of monetary surprises on the volatility of the 3‐ and 10‐year bond future instruments is significant and persistent. We have also documented a strong monetary policy effect on the mean returns of the exchange rate futures, indicating that unexpected monetary policy adjustments have a significant impact on the level of the exchange rate movements rather than on the volatility of the FX futures market.     

The reaction of spot and forward rates to new information

This paper examines the impact of new information on the term structure of exchange rates. In particular, the response of spot and forward exchange rates to anticipated and unanticipated weekly U.S. and Canadian money growth announcements, and the speed of adjustment of the foreign exchange market to these announcements are investigated. The results indicate that the unanticipated component of the announced changes in the U.S. money supply has an immediate negative effect on the foreign value of the U.S. dollar. This is entirely consistent with the assetmarket theory of exchange rate determination that postulates that exchange rates immediately adjust to reflect ‘new information’. The response of the forward market, however, appears to be weaker, lending support to the overshooting hypothesis.     

Does Real Exchange Rate Depreciation Boost Capital Accumulation? An Intertemporal Analysis

This paper examines the investment‐enhancing effect of real exchange rate (RER) depreciation in a two‐sector small open economy model where a representative firm in the tradable sector maximises its discounted profit over an infinite planning period. In this framework, a one‐time, permanent, unanticipated depreciation in the RER leads to a higher steady‐state level of capital stock and investment. This consequently increases the optimal investment rate associated with an arbitrary level of capital stock as the saddle path shifts upwards. In the benchmark calibration, the investment‐enhancing effect of RER depreciation is sizeable. One per cent depreciation in the RER leads to an increase of 0.4444 per cent in the rate of capital accumulation.     

Random perturbations of deterministic equilibria

This paper examines whether a small random deviation from a non-random policy process will destabilize the equilibrium exchange rate. The results focus on exchange rate dynamics when the government maintains a target zone or makes unanticipated deviations from a policy rule. With rational expectations small random shocks do not create large deviations from the policy rule exchange rate. If agents are approximately rational large deviations between exchange rates are possible.     

Government spending and the exchange rate

This paper investigates the effects of govenment spending on real and nominal exchange rates within the context of an open economy equilibrium rational expectations model. The model predicts that both real and nominal exchange rates appreciate in response to anticipated and unanticipated increases in government spending. Empirical evidence from Germany for the period 1975:2–1989:4 provides some weak support for the predictions of the model.     

Market efficiency broadcasted live: ECB code words and euro exchange rates

This paper examines the impact of the European Central Bank (ECB) monetary policy on euro exchange rate returns using an event study with intraday data for five currencies (the euro exchange rate versus the US dollar, the British pound, the Canadian dollar, the Swiss franc, and the Japanese yen). I construct two indicators of news about monetary policy stemming separately from policy decisions and the press conference. Estimation results show that the surprise component of communication has highly statistically significant effects on exchange rates, whereas the response of euro exchange rates to the unanticipated change in the policy rate is more muted. I also estimate the financial market impact on euro exchange rates of US, European and German macroeconomic news, and I show that the impact of the ECB press conference is economically important. The process of fully incorporating the ECB news shock takes about 1 h, and thus this result suggests that the whole press conference (both the Introductory Statement and the Q&A part) provides valuable information to market participants.     

News and the exchange rate revisited

This paper provides a theoretical framework to explain the increasing impact on the exchange rate of unanticipated money growth, with a stable short-term interest rate, and rising long-term rates. The assumptions of Purchasing Power Parity and Uncovered Interest Rate parity are relaxed. The appreciation of the currency is shown to be a direct result of the expected increase of future interest rates. A discussion is offered on the precise definition of the "surprise," under alternative assumptions. Heterogeneity of agents as regards exchange rate expectations, and the effect of long-term capital investments are also taken into account. It is shown that the surprise may have lagged effects on the exchange rate, and that its sign depends on the horizon of the portfolio investments (short or long). This paper has benefited from the comments of the participants at the 1996 International Atlantic Economic Conference in Paris. Financial support from the Instituto Valenciano de Investigaciones Económicas and the DGCYT under project PB94–1502 is acknowledged.     

High growth and low consumption in East Asia: How to improve welfare while avoiding financial failures

This paper analyzes certain policies that are typical of a number of rapidly growing East Asian countries in which a fixed exchange rate, combined with a surplus labor market, has made domestic assets relatively inexpensive, generating high rates of FDI as well as domestic capital formation. This “investment hunger” can lead to unanticipated declines in the returns to investment, and resulting financial insolvencies. Private consumption remains low and there are concerns that high savings rates cannot be sustained.We construct a dynamic general equilibrium model and apply it to a stylized Asian economy, loosely based upon China. We calibrate a benchmark equilibrium, and carry out various counterfactual simulations to analyze alternative policies, in particular tax cuts and exchange rate revaluations, as instruments in increasing private consumption while avoiding bank failures.     

Exchange Rate Exposure of Chinese Firms at the Industry and Firm Level

This study investigates the exchange rate exposure of Chinese firms at the industry and firm level based on the conventional capital asset pricing model (CAPM) framework. At the industry level, the dynamic conditional correlation MGARCH (DCC MGARCH) estimates demonstrate that the market model and three‐factor model are appropriate for exposure measurements, and industry returns are more likely to be exposed to unanticipated changes in the real exchange rate and the trade‐weighted effective exchange rate, particularly for manufacturing industries. At the firm level, although the seemingly unrelated regression (SUR) estimates vary across markets, it is apparent that there is a relationship between firm size and exposure effects, which also show that lagged exchange rate changes have significant exposure effects on firm returns. This study finally suggests that non‐financial firms should set up special commissions to hedge currency risks of their future cash flows.     

Overshooting in the foreign exchange market: Evidence from the 1970s

This paper analyzes the reaction of spot and forward exchange rates to unanticipated weekly money supply changes. The empirical results tend to support the (overshooting) hypothesis that equilibrium exchange-rate changes that occur in the short run in response to an unanticipated event exceed the equilibrium exchange-rate change in the long rung.     

Inflation and the Exchange Rate: The Role of Aggregate Demand Elasticity

This paper examines the effect of aggregate demand elasticity on the exchange rate when inflation occurs. We discover that both the source of the inflation, whether demand-pull or cost-push, and the elasticity of aggregate demand with respect to the price level, are of consequence for the exchange rate. We obtain two primary conclusions. First, the effect on the exchange rate of cost push inflation is ambiguous and is partially determined by the price level elasticity of aggregate demand. In particular, and assuming that the two examined countries have equivalent aggregate supply elasticities, we conclude that the nation with the less elastic aggregate demand function will see its currency appreciate relative to the other. Second, demand-pull inflation results in an unambiguous increase in the exchange rate but the size of that increase is partially a function of aggregate demand elasticity. Assuming again that two countries have equivalent aggregate supply elasticities, that country with the more elastic aggregate demand will experience currency appreciation.     

Between the hammer and the anvil: The impact of economic sanctions and oil prices on Russia’s ruble

Exchange rate fluctuations strongly affect the Russian economy, given its heavy dependence on foreign trade and investment. In the aftermath of the conflict between Russia and Ukraine that broke out early 2014, the Russian ruble lost 50% of its value against the US dollar. The impact of the conflict on Russia may have been amplified by sanctions imposed by Western countries. However, as Russia is heavily dependent on natural resource exports, another factor behind the deterioration could be the sharp decline in oil prices starting in summer 2014. Using high-frequency data on nominal exchange and interest rates, oil prices, actual and unanticipated sanctions, we provide evidence on forces underlying the ruble exchange rate. The analysis is based on cointegrated VAR models, where fundamental long-run relationships are implicitly embedded. The results indicate that the bulk of the depreciation can be related to the decline of oil prices. In addition, unanticipated sanctions matter for the conditional volatility of the variables involved.     

Local content requirement on foreign direct investment under exchange rate volatility

This paper analyzes the effects of exchange rate volatility of both the host country and the parent country on host-government policy related to local content requirement (LCR) on export-oriented foreign direct investment (FDI) in the context of an oligopolistic market in a third country. We, inter alia, find that an increase in the volatility foreign exchange rate decreases optimal LCR both under free entry and exit of foreign firms and when the number of foreign firms is fixed. We also find that the government uses a less strict LCR policy when the number of foreign firms is endogenous than when it is exogenous.     

Creative Destruction, Investment Volatility, and the Average Age of Capital

In this article, a new numerical procedure is used to compute the equilibrium of a vintage capital growth model with nonlinear utility, where the scrapping time is nonconstant. We show that equilibrium investment and output converge nonmonotonically to the balanced growth path due to replacement echoes. We find that the average age of capital is inversely related to output, which is consistent with recent micro evidence reinforcing the importance of the embodied question. We also find that an unanticipated permanent increase in the rate of embodied technological progress causes labor productivity to slowdown in the short run.

Devaluation,long-term contracts and rational expectations

This paper considers the effects of devaluation and expected devaluation on output, prices and foreign exchange reserves in a small open economy with overlapping two period wage contracts and rational expectations. A devaluation has an expansionary effect on output provided it is unanticipated by at least some contracts when it occurs. Expected devaluations, however, have no effect on prices until they take place. If a devaluation is expected, but fails to take place, output is reduced. Reserves increase in response to all devaluations; but the expectation of a devaluation causes a loss of reserves prior to its expected date.     

Modelling the impact of central bank intervention on exchange rate volatility under inflation targeting

This article empirically investigates the effect of central bank’s foreign exchange interventions on the level and volatility of the Uganda shilling/US dollar exchange rate (UGX/USD) under an inflation-targeting regime. Utilizing daily data spanning the period 1 September 2005, to 31 December 2015, we estimate a foreign exchange intervention model within a GARCH theoretic framework. Empirical results indicate that foreign exchange interventions have had mixed impact on the volatility of the exchange rate. We find that inflation targeting is capable of curbing temporary exchange rate shocks. Empirical results indicate that while order flow is capable of reducing exchange rate volatility, an increase in the operating target rate, the 7-day interbank rate tends to exacerbate exchange rate volatility. Our empirical results are robust to alternative model specifications. We argue that inflation targeting is an effective monetary policy tool for curbing exchange rate volatility.
