Foreign interest rate shocks and exchange rate regimes in East Asia

Using a theoretical dynamic stochastic general equilibrium model and an empirical panel vector autoregression, we assess the transmission of foreign real interest rate shocks on the volatility of various key macroeconomic variables in nine small open economies in East Asia taking into account the role of exchange rate regimes. Both the theoretical and empirical findings confirm the hypothesis that flexible exchange rate may work as a shock absorber when the economy is hit by foreign real interest rate shocks. The findings suggest a clear trade-off between the volatility of real exchange rate and real output to foreign interest rate shocks, both the US and G7 real interest rates, where the responses of real output are mitigated in countries that have more flexible exchange rate regime.     

Rational expectations,market shocks,and the exchange rate

The world economy has been subjected to numerous real shocks in recent years. In addition, purchasing-power parity seems to have collapsed. Critics of the monetary approach to the exchange rate have been quick to draw attention to these facts. This paper extends the basic framework of the monetary approach so that it provides a useful tool for explaining the impact of real shocks on the exchange rate and so that it is compatible with the existence of significant deviations from purchasing-power parity. The real shocks that are discussed include changes in commercial policy, the terms of trade, and productivity. It is demonstrated that real shocks influence the exchange rate through two distinct channels—a real-income channel and a deviations from purchasing-power-parity channel.     

Monetary policy credibility and exchange rate pass-through: Some evidence from emerging countries

Considering external constraints on monetary policy in emerging countries, we propose a semi-structural vector autoregressive model with exogenous variables (VARX) to examine the exchange rate pass-through to domestic prices. We demonstrate that a lower exchange rate pass-through is associated with a credible monetary policy aiming at controlling inflation. The empirical results suggest that the exchange rate pass-through is higher in Latin American countries than in East Asian countries. The exchange rate pass-through has declined after the adoption of an inflation targeting monetary policy.     

Monetary Stabilisation Policy in a Monetary Union: Some Simple Analytics

We do two things in this paper. First, we look at some simple models of monetary decision making in a monetary union and ask how much more variable a country's output and inflation is likely to be if it joins the union. We answer this analytically and then go on to 'calibrate' the simple model. The model has few structural equations, but it is useful in allowing us to examine how the variability of output and inflation are likely to change as key parameters change. Our conclusions on this front are likely to be sensitive to model specification. However, we also identify a second best issue concerning the optimal make–up of the monetary union which is likely to be more robust: namely that only when all members of the union have the same structural parameter values (and shocks are perfectly correlated) will it be optimal for a new member to have these same structural parameter values.     

The fallacy of composition and contractionary devaluations: output effects of real exchange rate shocks in semi-industrialised countries

This paper studies whether intra-developing country price competitionhas significant effects on the short-run growth of output indeveloping countries that are specialised in manufactured exports.Regression estimates using the generalised method of momentsapplied to annual panel data for 17 semi-industrialised countriesin 1983–2004 show that these countries exhibit a ‘fallacyof composition’, in the sense that a real depreciationrelative to competing developing country exporters increasesthe home country's growth rate at the expense of its competitors'growth. The results also suggest that real depreciations forthese developing countries relative to the industrialised countriesare contractionary.     

Monetary policy and the transmission of oil shocks

This paper provides evidence on the role played by monetary policy in the transmission of oil shocks to the US economy. We show that for the period since 1986, oil shocks have had a negative effect on stock returns, regardless of whether the oil shock is defined as the percentage change in the price of oil or a nonlinear transformation of that series. We then demonstrate that there is no relationship between the reaction of individual stock prices to oil shocks and to monetary policy shocks. This implies that oil shocks do have effects on the economy beyond their effect on monetary policy. We conclude that systematic monetary policy is not as effective as suggested in some previous studies.     

Monetary and real shocks in a monetary Union: The Swiss case

We analyze to what extent real and monetary shocks affect price levels and real exchange rates in seven Swiss regions. A structural time series model is set up and estimated using the Kalman filter under two assumptions on the persistence of monetary shocks. We find that the variability of changes in price levels is mainly due to real shocks. The variance of monetary shocks is small but the monetary component of inflation differences across regions differs from zero with some persistence. As the Swiss case shows this does not seem to be a major obstacle to forming a monetary union.We thank Ernst Baltensperger, Tobias Rötheli, and participants at the Econometric Society European Meeting 1994 for stimulating discussions.

扩张性货币政策批判:货币政策传导机制的无效性

西方经济学所说货币政策传导机制,包括利率渠道、资产价格渠道即利率渠道基础上的投资效应和财富效应、信贷渠道、汇率渠道等,在积极的或扩张性货币政策方面都是难以奏效的。扩张性货币政策的短期效果也难以证实,而且推动通胀、加剧过剩、浪费资源、加剧分化,损害长远经济发展,在长期中是负效应而不是中性。正确的货币政策原则只能是适应性的。     

Optimal Monetary Policy

Optimal monetary policy maximizes the welfare of a representative agent, given frictions in the economic environment. Constructing a model with two sets of frictions—costly price adjustment by imperfectly competitive firms and costly exchange of wealth for goods—we find optimal monetary policy is governed by two familiar principles. First, the average level of the nominal interest rate should be sufficiently low, as suggested by Milton Friedman, that there should be deflation on average. Yet, the Keynesian frictions imply that the optimal nominal interest rate is positive. Second, as various shocks occur to the real and monetary sectors, the price level should be largely stabilized, as suggested by Irving Fisher, albeit around a deflationary trend path. Since expected inflation is roughly constant through time, the nominal interest rate must therefore vary with the Fisherian determinants of the real interest rate. Although the monetary authority has substantial leverage over real activity in our model economy, it chooses real allocations that closely resemble those which would occur if prices were flexible. In our benchmark model, there is some tendency for the monetary authority to smooth nominal and real interest rates.     

Large data sets,nonlinearity and the speed of adjustment to real exchange rate shocks

A well known puzzle in international finance concerns the very slow speeds of adjustment of real exchange rates observed in response to shocks. In this article, we explore whether allowing for a wide range of influences on the real exchange rate in a nonlinear framework can help resolve this puzzle. Using, recently proposed econometric methods for summarizing very large macroeconomic data sets into a small number of observable factors, we find that there is a long run relationship between these factors and real exchange rates. When put into a nonlinear framework, we find that allowing for the effects of macroeconomic factors dramatically increases the measured speed of adjustment of the real exchange rate.     

前瞻性货币政策反应函数在我国货币政策中的检验

本文在泰勒等西方学者对货币政策反应函数研究的基础上,构造一个适合我国国情的前瞻性货币政策反应函数,从市场利率(同业拆借利率)、管制利率(存贷款利率)以及两者利差三个层次,通过该反应函数对我国货币政策的实证检验结果发现,一方面,该反应函数能够很好地描述同业拆借利率、存贷款利率和两者利差的具体走势,能够为我国货币政策的制定提供一个参考尺度,以衡量货币政策的松紧。另一方面,检验结果表明,三个层次的利率对预期通胀率和预期产出的反应绝大多数都不足,这说明,我国货币政策是一种内在不稳定的货币政策。     

Monetary policy shocks and productivity measures in the G-7 countries

An implication of two-country international real business cycle models is that total factor productivity should be an exogenous stochastic process. Economic theories which feature labor hoarding, variable capacity utilization, and increasing returns predict that measured productivity shifts are not exogenous; instead, expansionary aggregate demand shocks should lead to an increase in measured productivity. For each of the G-7 countries, this paper measures quarterly aggregate total factor productivity for the domestic country and its rest-of-world (G-6) counterpart. In each case the domestic productivity measures are not strictly exogenous: expansionary U.S. monetary policy shocks, as well as other G-6 monetary policy shocks, lead to productivity expansions. The evidence indicates that international business cycle models are misspecified unless they feature endogenous productivity mechanisms.Received: June 2001, Accepted: December 2001, JEL Classification: E5, F4Correspondence to: Charles L.

Real exchange rate and exchange rate policy in Hungary

Five real exchange rate indicators are computed to assess the international competitiveness of Hungarian industry. These indicators are explained in econometric equations by employment, unemployment, productivity, interest spread and real producer wage. Causality tests reveal that external performance has an impact on real exchange rates, and contributes to explaining real exchange rates. There is very limited scope for policy intervention to constrain the negative effects of capital inflows without incurring other costs.
