汇率制度与宏观经济政策环境——以加拿大为例

加拿大属于典型的资源性经济,加元的汇率变化多受国际商品和石油价格的影响,超出了国内货币政策的控制范围,是独立浮动或是固定汇率？经过两次试验后,加拿大政府坚定地选择了独立浮动汇率制度,并最终实现了汇率政策与货币政策脱离,以此给予了加拿大银行较大的决策空间,使后者专注于维持较低的通货膨胀环境。同时,加拿大政府努力为汇率制度创造有利的宏观经济政策环境,财政政策和货币政策分工明确、相互支持,为汇率制度和经济增长奠定了可持续的坚实基础。本文以加拿大浮动汇率制度为主线,从财政政策、货币政策、政策搭配角度讨论其宏观经济政策框架,分析加元汇率制度的运行环境。在此基础上,本文探讨加拿大汇率政策及浮动汇率制度的作用与功能。本文第五部分对加拿大银行提出的汇率预测模型作出了较深入的分析。     

Inflation volatility,economic growth and monetary policy in Bangladesh

This article provides an overview of the trends and movements of CPI-inflation in Bangladesh since the early 1950s and examines the key issues in rule-based monetary policy for price stability, implying low and stable inflation, in this country. Under a fixed exchange rate system, inflation in Bangladesh was moderately high and volatile during the 1950s and 1960s. Since the country’s independence from Pakistan in 1971, inflation in Bangladesh has remained moderately high on average and highly volatile and persistent under a fixed-pegged exchange rate system or under a managed floating system since 2003. Using data from the early 1970s or earlier depending on data availability, the article undertakes both Granger-causality and the structural vector autoregression (SVAR) analysis with two models. The first model is comprised of such variables as inflation, the real interest rate, the real exchange rate and output growth, and the second model is comprised of the volatilities of money growth, real output growth and inflation. Then, based on the empirical findings, the article concludes that a rule-based monetary policy, namely monetary targeting or inflation targeting, remains appropriate for Bangladesh provided that it adopts a more flexible, if not freely floating, exchange rate system. The article suggests that the use of monetary policy to achieve multiple objectives under a fixed-pegged exchange rate system creates a time-inconsistency problem, reduces monetary policy credibility and makes it (monetary policy) ineffective in lowering inflation and its volatility. Low credibility of monetary policy in particular raises inflation persistence. Within the present monetary-policy framework in Bangladesh, the article illustrates how the fixed-pegged exchange rate system has generated money growth volatility in the presence of large-scale inflows of overseas workers’ remittances and readymade garments export earnings. This does not seem to be a concern of the central bank of Bangladesh (Bangladesh Bank); rather, it (Bangladesh Bank) pursues monetary-base targeting to keep inflation low and stable after considering economic growth. The consequent diminishing credibility of monetary policy has kept inflation volatile and persistent, which has adversely affected economic growth.     

Optimal monetary policy for a small open economy

This paper focuses on the design of monetary policy rules for a small open economy. The model features optimizing behavior, general equilibrium and price stickiness. The real exchange rate is shown to affect the firm's real marginal cost, aggregate supply and aggregate demand. The welfare objective depends on the openness of the economy, and the optimal policy rule differs from that which obtains in a closed economy. The inflation versus output gap stabilization trade-off is caused by the real exchange rate. The implied optimal monetary policy regime is domestic inflation target coupled with controlled floating of the real exchange rate.     

COSTS AND BENEFITS OF EXCHANGE RATE STABILITY: CANADA'S INTERWAR EXPERIENCE

In January 1929, the Canadian government suspended gold exports and implemented a floating exchange rate regime that endured until the onset of World War II. In sharp contrast to the experience of other countries that left the gold standard, Canada's deflation and declining economic activity continued until 1933. This paper examines why the Canadian government chose to follow a restrictive monetary policy and how that policy affected the Canadian exchange rate. We show that the chosen policy was rational—given the government's assumptions and objectives—and that it was consistent with fiscal policy. In so doing, we argue that the government's commitment to monetary stability was credible. We show that one can explain the Canadian exchange rate's behavior by a simple expectations-based model of exchange rate determination, given external events and the government's monetary policy.     

Exchange Rate Regimes and Inflation: Evidence from India

Abstract

Exchange rate stability is crucial for inflation management as a stable rate is expected to reduce domestic inflation pressures through a ‘policy discipline effect’ – restricting money supply growth, and a ‘credibility effect’ – inducing higher money demand and reduced velocity of money. Alternatively, the ‘impossibility trillema’ of Mundell (1961a Mundell, R. A. (1961a). Capital mobility and stabilization policy under fixed and flexible exchange rates. Canadian Journal of Economics and Political Science, 29, 475–485. doi: 10.2307/139336[Crossref], [Web of Science ®] , [Google Scholar], 1961b Mundell, R. A. (1961b). Flexible exchange rates and employment policy. Canadian Journal of Economics and Political Science, 27, 509–517. doi: 10.2307/139437[Crossref], [Web of Science ®] , [Google Scholar]) predicts that in the presence of an open capital account, a stable exchange rate may lead to lack of control on monetary policy and, hence, higher inflation. Using a monetary model of Inflation, this paper investigates the impact of the ‘empirically-claimed’ de facto stable exchange rate regime on inflation in India during different sub-periods of exchange rate stability. The results show that the impact of exchange rate regime on inflation is not visible in the Indian case, which could be because of the offsetting sterilization policy undertaken by the Reserve Bank of India (RBI) during expansionary money supply growth resulting from its large-scale intervention to even out exchange rate volatility.     

Exchange Rate Asymmetry and Flexible Exchange Rates under Inflation Targeting Regimes: Evidence from Four East and Southeast Asian Countries

While many have underscored the role of a flexible exchange rate policy under an inflation targeting (IT) regime, very few studies have examined what actually happens to exchange rate policy once the emerging market announces that it will adopt inflation targeting. The central contention of this paper is that while the adoption of an inflation targeting (IT) policy may lead to more flexible exchange rate movements, for various reasons it is possible that the degree of flexibility will be significantly higher on one side of the market. In this study, we demonstrate that four Asian economies—namely, Indonesia, Korea, the Philippines and Thailand—whom were among the first group of emerging markets to embrace the inflation targeting framework of monetary policy, tend to adopt a form of asymmetrical exchange rate behavior, wherein appreciation pressures are restrained more substantially than depreciation pressures.     

How should emerging economies float their currencies?

Floating exchange rates seem to be gaining ground in Latin America, East Asia and the transition economies. The recent crises left many economies with no alternative but to float. Others have moved toward floating, searching for greater flexibility and insulation from external shocks. The question for most emerging market economies, then, is no longer to float or not to float, but how to float. Four issues arise in this regard. The first is how to float and have low inflation. The second is whether floating provides as much insulation as conventional theory predicts, especially in the presence of dollarized liabilities. Which leads to the third point: the relationship between the stability of the exchange rate and that of the financial system. The fourth is how to conduct monetary policy under a float, and the role of inflation targeting. We consider each of these points in turn, and conclude that a workable model of how to float seems to be emerging from the so‐far successful experience of countries like Chile and Brazil. It involves the adoption of an inflation target as the main anchor for monetary policy, coupled with a monetary policy reaction function that — aside from reacting to the output gap and other determinants of the inflation rate — reacts also partially to movements in the nominal exchange rate.

Does money have a role in the inflation process? Evidence from Australia

Inflation, defined as a sustained increase in the price level, is considered a monetary phenomenon, as it can be explained within the framework of money‐demand and money‐supply relationships. In the extant literature, money growth is shown to remain causally related to inflation across countries and over time, irrespective of the exchange rate regime and stability of the money‐demand function. Nevertheless, emerging literature suggests a diminishing role of money in the conduct of monetary policy for price stability, especially under inflation targeting. Monetary policy in Australia under inflation targeting since 1993 is an example of policy that denies a relationship between money growth and inflation. The proposition that money does not matter insofar as inflation is concerned seems odd in both theory and the best‐practice monetary policy for price stability. This paper uses annual data for the period 1970–2017 and quarterly data for the period 1970Q1–2015Q1. It deploys both the Johansen cointegration approach and the autoregressive distributed lag (ARDL) cointegration approach to investigate for Australia whether money, real output, prices and the exchange rate (non‐stationary variables) maintain the long‐run price‐level relationship that the classical monetary theory suggests in the presence of such stationary variables as the domestic and foreign interest rates. As expected, the empirical findings for Australia are consistent with the classical long‐run price‐level relationship between money, real output, prices and the exchange rate. The error‐correction model of inflation confirms the presence of a cointegral relationship among these variables; it also provides strong evidence of a short‐run causal relationship between money supply growth and inflation. On the basis of a priori theoretical predictions and empirical findings, the paper draws the conclusion that the monetary aggregate and its growth rate matter insofar as inflation is concerned, irrespective of the strategy of monetary policy for price stability.     

Evaluating inflation targeting as a monetary policy objective for India

This study formulates a small open economy model for India with exchange rate as a prominent channel of monetary policy. The model is estimated using the Instrumental Variable-Generalized Methods of Moments (IV-GMM) estimator and evaluated through simulations. This study compares different cases of domestic and CPI inflation targeting, strict and flexible inflation targeting, and simple Taylor type rules. The analysis highlights the unsuitability of simple Taylor-type monetary rules in stabilizing the Indian economy and suggests that discretionary optimization works better in stabilizing this economy. There seems to be a trade-off between output gap stabilization and exchange rate stabilization in flexible domestic inflation targeting and CPI inflation targeting respectively. However, flexible domestic inflation targeting seems a better alternative from an overall macro stabilization perspective in India where financial markets are still not sufficiently integrated to ensure quick transmission of interest rate impulses and existence of rigidities in the economy.     

Stability of Money Demand and Monetary Policy in Papua New Guinea (PNG): An Error Correction Model Analysis

An error correction model (ECM) is used to study the Properties of money demand and to evaluate the appropriate monetary policy in PNG. The study confirms that the determinats of money demand are real GDP, nominal interest and inflation rate. The income elasticity of money demand is very low. The demand for money in PNG was stable during 1979-95, suggesting that the monetary targeting regime by the PNG Central Bank is feasible. However, as PNG proceeds with economic reforms that Includes financial sector reform and a floating exchange rate regime, the stability of the demand for money may have to be re-examined periodically. The best approach for conducting the monetary policy in PNG is to target the inflation rate. [E41, E52, C22]     

A NEW COMPARATIVE STUDY ON THE FREE‐FLOATING AND CURRENCY BOARD REGIMES IN HONG KONG

This study aims to compare the performance of free‐floating and currency board regimes for Hong Kong by examining historical data of the two on the output growth and inflation rate. Structural vector autoregression has been applied in the empirical analysis. Without making a strong assumption of unit variance in the residual matrix, this study applies a more natural approach proposed by Cecchetti and Rich to recover the structural parameters. The study has further investigated the recovery of the economy under a demand shock under different exchange rate regimes, in order to provide some evidence to answer why Hong Kong's recovery process after the Asian financial crisis is relatively longer than that in other economies with a managed floating exchange rate regime. New evidence in this study indicates that output recovers much faster in a flexible exchange rate regime than in a fixed exchange rate regime after an aggregate demand shock. Furthermore, this study has applied a more robust method in the counterfactual analysis when comparing the two regimes. New evidence in this study suggests that a free‐floating regime may generate much smaller output variance in Hong Kong and deliver higher output and price levels to Hong Kong.     

Inflation Dynamics in India: Relative Role of Structural and Monetary Factors

This paper examines the relative role of structural and monetary factors in the variation of inflation in India over the period 1996–1997:Q1 to 2013–2014:Q4. The paper finds that both the monetary factors and the output gap has significant role. The role of the output gap in inflation is found more prominent than the monetary factors like broad money growth, interest rate and change in exchange rate. The depreciation of exchange rate and broad money growth stimulates inflation where as the interest rate is identified as an anti-inflationary monetary instrument. In view of a comprehensive policy for price stability, it is imperative to know the role of sectoral output gap in inflation. The paper, therefore, enquires the relative role of the primary, secondary and tertiary sector output gap in inflation. Output gap of each of these three sectors provokes inflation where the contribution of tertiary sector output gap is found to be the maximum followed by the primary sector and the secondary sector output gap. The prominent role of the output gap and comparatively passive role of monetary factors does not necessarily imply a non-effective monetary policy but suggests that controlling inflation only through the monetary management may not be effective.

     

Oil shocks and monetary policy rules in emerging economies

We examine the effects of shocks in the oil market on key macroeconomic variables in small open economies using a dynamic stochastic general equilibrium model with sticky prices and imperfect competition under different monetary policy rules. The numerical solutions show that the types of exchange rate regimes and monetary policies could partly explain the trends in macroeconomic volatilities considering negative shocks to oil supply (Hamilton, 1983) and positive shocks to oil demand (Kilian, 2009). These findings are confirmed in vector autoregressive responses for Chile and Israel with inflation targeting under flexible exchange regimes and Hong Kong with fixed regime.     

Comparing monetary policy reaction functions: ECB versus Bundesbank

This paper compares the European Central Bank’s (ECB) conduct of monetary policy with that of the Bundesbank. Estimated monetary policy reaction functions show that the ECB reacts similarly to expected inflation but significantly stronger to the output gap than the Bundesbank did. Theoretical considerations suggest that this stronger response to the output gap may rather be due to a higher interest rate sensitivity of the German output gap than to a higher weight given to output stabilisation in the objective function of the ECB. Counterfactual simulations based on the estimated interest rate reaction functions reveal that German interest rates would not have been lower under a hypothetical Bundesbank regime after 1999. However, this conclusion crucially depends on the assumption of an unchanged long-run real interest rate for the EMU period and is reversed when the Bundesbank reaction function is adjusted for the lower long-run real interest rate estimated for the ECB regime.

RE-EXAMINING THE EFFECTIVENESS OF STABILISATION POLICY

This paper develops an alternative international macroeconomic model for evaluating the effectiveness of fiscal and monetary policy in stabilising national income under fixed and floating exchange rates. It encompasses national output and income, saving, investment, money and capital flows and linkages between the exchange rate, price levels and real interest rates consistent with international parity conditions. It demonstrates that the nature of government spending is pivotal to the effectiveness of fiscal policy, revealing that, ceteris paribus , higher public consumption expenditure contracts national income and depreciates the exchange rate, whereas higher productive public investment spending has opposite effects. The framework also shows that the effectiveness of fiscal and monetary policy as macroeconomic policy instruments is not ultimately dependent on the exchange rate regime.     

The transmission of inflation between the United States and Canada: An empirical analysis

This paper investigates the causal patterns, in the sense of Granger, which characterize the relationships between U.S. and Canadian inflation rates under different exchange rate regimes. Both bivariate and multivariate models are considered. The results suggest that the flexible exchange rate period of the 1950s exhibits no insulating effects with causal inferences similar to those from the fixed rate era of the 1960s. For the flexible rate period of the 1970s the bivariate model indicates that U.S. and Canadian inflation are independent but when the model is expanded to include money growth rates in each country, evidence of a direct, nonmonetary causal link from U.S. inflation to Canadian inflation is found.     

The effects of the monetary policy regime shift to inflation targeting on the real interest rate in the United Kingdom

This paper studies the effects of the monetary policy regime shift to inflation targeting on the stochastic properties of the real interest rate in the U.K. The empirical analysis suggests a constant mean of the real interest rate that shifts with the monetary policy regime change to inflation targeting in October 1992. The mean-reverting level of the real interest rate has decreased from 5.1% to 2.3% per annum with the change in monetary policy to inflation targeting. In addition, the shift in monetary policy regime to inflation targeting has reduced the volatility of the real interest rate and increased the persistence of real interest rate deviations from the mean. The results suggest that the central bank can affect the stochastic properties of the real interest rate through the choice of monetary policy regime over a long period of time.     

中间汇率制度下货币、财政政策效应比较及政策建议

蒙代尔-弗莱明模型(M-F模型)研究了固定汇率制和浮动汇率制下财政、货币政策的有效性。将其拓展到中间汇率制度下发现,无论资本的流动性如何,扩张性的财政政策和货币政策基本有效,其效应介于固定汇率制和浮动汇率制的情况之间。实行中间汇率制度的国家在进行宏观调控时,最应该运用财政、货币政策搭配方法,此时政策效果最好。     

Monetary and fiscal policy interactions in a post Keynesian open-economy model

Using a post Keynesian model, this study aims to analyze the stabilizing role of fiscal and monetary policies in an open economy with a managed exchange rate regime. The real exchange rate is modeled as an endogenous variable and inflation explained using the conflicting claims approach. The dynamic properties of macroeconomic equilibrium are evaluated in different regimes of fiscal and monetary policies. The main result of this study suggests that the preferred policy regime is the one in which economic authorities are complementary and fiscal policy plays an explicitly active role. In this regime, the fiscal policy must commit to the target for the rate of capacity utilization and the monetary authority must commit to the inflation target.
