On the Link Between Exchange‐rate Regimes,Capital Controls and Monetary Policy Autonomy in Small European Countries, 1979–2000

We investigate international monetary‐policy transmission under different exchange‐rate and capital‐account regimes in eleven small, open economies during the 1980s and 1990s. We find no systematic link between ex‐post monetary‐policy autonomy and exchange‐rate regimes. Capital controls appear to have provided a degree of temporal insulation from foreign monetary policy shocks, though not strict autonomy. The results are consistent both with short‐term autonomy for small countries even under fixed exchange rates and an open capital account, and with long‐term dependence under flexible exchange rates and an independent stability target. Results also indicate that euro‐area market interest rates are significantly more responsive to the development of the corresponding US rate than were the previous national rates.     

Exchange rate expectations and monetary policy

The adjustment process to a monetary disturbance is studied in a model of perfect capital mobility and flexible exchange rates. Exchange rate expectations are emphasized and used to establish an adjustment process. In the short run, a monetary expansion gives rise to a depreciation in the exchange rate and a reduction in saving due to the terms of trade deterioration. The exchange rate depreciation, in the short run, may be in excess of the long-run depreciation. The trade balance in the short run may worsen. The long-run equilibrium of the analysis conforms to the Mundell-Fleming results that establish the force of monetary policy under flexible rates.     

Monetary Policy Independence under Flexible Exchange Rates: An Illusion?

I analyse whether countries with flexible exchange rates are able to pursue an independent monetary policy, as suggested by traditional theory. I use data for three Latin American countries with flexible exchange rates, inflation targeting and capital mobility – Chile, Colombia and Mexico – to investigate the extent to which Federal Reserve actions are translated into local central banks' policy rates. The results indicate that there is significant ‘policy contagion’ and that these countries tend to ‘import’ Fed policies. The degree of monetary policy independence is lower than what traditional models suggest.     

Flexible exchange rates,unemployment and stabilization policy effectiveness

The paper presents a general equilibrium model of a small flexible exchange rate economy comprising asset, goods, and labor markets. Viewing the exchange rate as determined proximately in asset markets, the study examines its influence on the excess demand for labor and for output and, correspondingly, its impact on the level of unemployment and external imbalance. The role of exchange rate expectations is central to the present analysis, which reconsiders, in that light, the conventional conclusions about monetary and fiscal policy effectiveness under flexible exchange rates.     

The employment effects of tariffs under a free exchange rate regime: A monetary approach

This paper develops a ‘monetary’ approach for the analysis of tariff policy under a free (flexible) exchange rate regime. The paper concludes that the imposition of a tariff unambiguously causes a deterioration in the level of employment under free rates even without a Laursen-Metzler effect on saving.     

股票市场开放条件下的货币政策效应分析

本文探讨了在股票市场开放条件下,股票市场的国际资本流动对货币政策的影响。在开放经济条件下,对在东道国投资的国际投资者来说,如果股票投资比债券投资更重要,那么货币政策比财政政策相对有效的观点难以成立。扩张性货币政策使国内利率下降,但利率下降会增加股票投资的预期收益,这会吸引国际资本流入,从而导致本币升值,因而扩张性货币政策对产出的净影响是不确定的。浮动汇率体制有利于减缓外部冲击。     

Segmented asset markets and optimal exchange rate regimes

This paper revisits the issue of the optimal exchange rate regime in a flexible price environment. The key innovation is that we analyze this question in the context of environments where only a fraction of agents participate in asset market transactions (i.e., asset markets are segmented). Under this friction alternative exchange rate regimes have different implications for real allocations in the economy. In the context of this environment we show that flexible exchange rates are optimal under monetary shocks and fixed exchange rates are optimal under real shocks.     

Protectionism and the case for flexible exchange rates: A reexamination

This paper reexamines the arguments by early proponents that flexible exchange rates would lessen the incentives for protectionism and also permit countries to pursue independent monetary policies. We argue that there is a basic inconsistency between these two arguments; the pursuit of independent monetary policy can lead to situations which involve very strong pressures on policy-makers to engage in protection. A theoretical analysis supporting our argument is developed, and some circumstantial evidence is presented.     

Is there an optimal crawl?

This paper shows that optimal exchange rate policy can be defined in terms of either a long-run secular policy or a short-run stabilization policy. The rate of crawl which maximizes real per capita consumption is shown to often differ from the exchange rate movements produced under fixed or floating exchange rates. And the optimal program for dealing with short-run speculative capital flows will involve both discrete and gradual exchange rate changes. It is also argued that domestic monetary policy and exchange rate policy are not independent instruments.     

Reforming the GATT: The use of trade measures for balance-of-payments purposes

The GATT rules which govern international trade are to be reformed during the current Multilateral Trade Negotiations. It is widely agreed that among the rules most in need of change are those relating to the use of trade policy measures, such as import quotas and surchages, for balance-of-payments purposes. This article reviews the role of such measures under international monetary regimes based on both fixed and flexible exchange rates, and concludes that they should no longer be authorized by the GATT. If they do remain part of the system, a number of major changes are needed in both the substantive and procedural rules which govern their use.     

The short run efficacy of monetary policy under floating exchange rates reconsidered

This paper disputes the argument that the short-run effectiveness of monetary policy in stabilizing domestic output under floating rates is necessarily reduced if elasticities of demand for imports and exports with respect to the current exchange rate are low and capital flows depend on the exchange rate. It is shown that the relative efficacy of monetary changes is determined by the interest rate elasticity of international interest payments and receipts and the effect of exchange rate variations on the demand for money in addition to the exchange rate elasticities of trade and capital flows.     

The resource reallocation costs of fixed and flexible exchange rates: A counterexample

This paper questions the view that resource reallocation costs are a disadvantage of a flexible exchange rate system relative to a fixed exchange rate. It is shown that reallocation costs of a flexible exchange rate are not necessarily greater than and indeed may be less than, those under a fixed exchange rate. A method is developed for testing this hypothesis. Applying the technique to Canadian exchange rate policy for 1953–1977 provides a counterexample to the view that reallocation costs are a disadvantage of flexible exchange rates.     

“三元悖论”与中国汇率制度选择

＂三元悖论＂的基本原理是指在货币政策独立、资本自由流动和固定汇率这三个经济目标中最多只能同时实现两个,而该理论本身也存在理论假设过于绝对化,组合难以有效实现,政策组合难以执行的局限性。基于对中国资本流动现状和货币政策有效性分析和＂三元悖论＂的基本原理分析,得出我国的汇率制度选择终级目标是实现＂货币政策独立＋资本自由流动＋自由浮动汇率＂的政策组合。     

An Empirical Analysis of the Determinants of Interest Rates in Ghana

ABSTRACT

This paper provides an empirical analysis of the determinants of the bank lending rate in Ghana using annual time series data from 1970 to 2013. We found evidence of a long-run equilibrium relationship between the average lending rate charged by commercial banks and its determining factors. In the long run, bank lending rates in Ghana are positively influenced by nominal exchange rates and Bank of Ghana’s monetary policy rate but negatively with fiscal deficit, real GDP and inflation. We also find positive dependence of the bank lending rate on exchange rates, and the monetary policy rate both in the short and long run. Specifically, our findings reveal that the Bank of Ghana’s monetary policy rate and the exchange rate, by far, show strong contemporaneous effects on the average bank lending rate in Ghana.     

利率政策与汇率政策协调搭配的文献综述

当前,我国经济已经进入了一个市场化与国际化的转型时期,在经济全球化背景下,利率政策和汇率政策在我国货币政策中的作用日益显著。我国很多学者在这一领域进行了积极的探索,部分成果实现了学术突破,但对于价格型货币政策即利率政策和汇率政策的综合研究还远远不够丰富和深入。我国应进一步深入研究利率政策和汇率政策的交互作用下对中国宏观经济的影响程度,这种影响是否与货币当局的预期相吻合;包含汇率政策在内的扩展的泰勒规则在中国经济的适应性;研究价格型货币政策工具之间的协调机制。通过梳理利率与汇率的关系、利率政策与汇率政策有效搭配的相关理论,可以更好地为新时期我国利率政策和汇率政策的协调搭配提供参考。     

中国货币政策对美国货币政策独立性的实证分析

在外汇储备快速增加和汇率制度面临选择的背景下,中国货币政策的独立性备受关注。本文运用Ordered Probit模型,对中国货币政策相对美国货币政策的独立性进行了实证分析。结果表明:1998年1月至2011年6月,中国基本保持了货币政策的独立性;从1998年1月至2005年6月和2005年7月至2011年6月汇率浮动幅度有明显差异的两个时段分析我国货币政策的独立性的差异,发现人民币汇率浮动幅度的放宽并未导致中国货币政策独立性的增强,放宽汇率管制并不能增强中国货币政策的独立性。     

美联储量化宽松货币政策正常化与人民币汇率变动——基于时变参数向量自相关模型的研究

2015年后，随着量化宽松货币政策正常化和人民币汇率进入双向波动新常态，美国货币政策对人民币汇率的外溢效应日益显著。通过构建时变参数向量自相关模型对2008-2018年美联储量化宽松货币政策的实施和退出对人民币汇率的溢出效应进行研究，结果表明：美联储加息在滞后一季度作用人民币兑美元先升值后贬值，加息通过中美利差、产出差、货币供给之差分别作用于人民币兑美元贬值、升值和升值，利差渠道是主要作用渠道；美联储资产负债表扩张和缩减分别带来人民币汇率的升值和贬值，且扩张的升值影响大于缩减的贬值影响；美联储资产负债表和利率政策有一定替代性，替代关系存在明显的结构效应；美联储资产负债表的扩张和缩减分别带来中国银行间市场利率的下降和回升，两国利率表现出一定联动性。     

Target zones for the US dollar?

The discussion of target zones for flexible exchange rates is evidence of the desire to experiment with new instruments for stabilising the international monetary system. What distinguishes target zones from systems of flexible and fixed exchange rates? What form should they take? How should one regard the various objections to target zones?     

A dynamic model of tariffs,output and employment under flexible exchange rates

A portfolio balance model of the open economy with imperfectly flexible wages and rational expectations is used to analyze the macroeconomic effects of commercial policy. Previous analyses have led to the ‘counterintuitive’ and ‘almost inconceivable’ conclusion that, under flexible exchange rates, a tariff is contractionary. By considering a tariff in a dynamic setting and focusing on the process of adjustment, it is shown that there may exist a tradeoff between a tariffs short-run and long-run effects. In certain circumstances, a tariff imposed under flexible exchange rates increases output and employment initially while reducing them subsequently.     

Monetary policy and the yield curve in an emerging market: the Greek case

This paper explores the impact of monetary policy actions on the nominal term yield curve in the Greek money market. Essentially, the monetary transmission mechanism is under scrutiny in testing monetary policy effectiveness. We focus on the dynamic inter-relationship between the short-term monetary policy instrument (Overnight rate) and market rates across the term structure. The findings are in accordance with the fact that Expectations Hypothesis monetary policy actions have a significant impact on all market rates; however, the impact is decreasing monotonically with maturity of the interest rate.
