关税、货币政策与中国实际均衡汇率

加入WTO后 ,降低进口品关税等措施将影响人民币均衡汇率水平 ,同时开放经济下国内货币政策、财政政策等宏观经济政策调整也会改变均衡汇率水平。本文运用动态一般均衡的方法 ,探讨中国在加入世界贸易组织之后 ,关税税率调整、货币供应量增长率改变、财政政策调整等措施对实际均衡汇率的长期效应。把货币引入生产函数和消费者的效用函数 ,我们扩展了由Turnovsky提出的两商品资本积累模型 ,利用参数赋值(calibration)的方法进行了均衡状态下的比较静态分析。研究发现降低进口品关税使人民币面临贬值压力 ,而政府增加税收 ,减少对贸易品的消费则有利于人民币的保值和升值。实证研究结果表明 :国外实际利率水平下降 ,实际货币供应量增长率降低都将引起人民币均衡汇率贬值。     

Time Inconsistency and the Exchange Rate Channel of Monetary Policy

This paper analyses time–inconsistency problems related to the exchange rate channel of monetary policy. Within a simple open–economy macroeconomic model, where the exchange rate is the only forward–looking variable, we show that a difference emerges between optimal policy under discretion and under commitment. Moreover, the nature of the time–inconsistency problem resembles that resulting from standard New Keynesian models: when cost–push shocks occur, the exchange rate channel gives rise to excessive output stabilisation and insufficient inertia in monetary policy under a discretionary policy.

Money,Interest Rate and Foreign Exchange Rate As Indicator Variables Of Monetary Policy

Since monetary policy operations affect the ultimate targets such as real income and prices with considerable time lags, this papers attempts to identify the indicator variable of monetary policy in Korea by using autoregression tests, variance docompositions of VAR forecasts and cointegration analyses. The results show that in Korea unlike the U.S., a broad concept of money, interest rate and foreign exchange rate, taken together, could serve as the indicator variables. In particular, M3, But not M2 nor MCT, is significantly related to real income both in the short-run and in the long-run. Such a finding rejects the practice of controlling either M2 or MCT which the Korean monetary authority had exercised before implementing the recent IMF financial-reform program. [E5]     

我国货币政策与人民币汇率的互动关系研究

基于SVAR模型研究我国货币政策与人民币汇率的相互作用关系,发现我国货币政策对汇率冲击的反应具有逆经济风向的操作特征,汇率升值,货币政策扩张;而人民币汇率对货币政策冲击的反应也符合经济理论,货币政策扩张会引起人民币汇率贬值。同时,在货币供应量作为货币政策变量时,汇率水平的反应表现为经典的超调现象,但在名义利率作为货币政策变量时,汇率的反应曲线则表现为延迟的超调现象。总体上,我国货币政策对人民币汇率变动非常敏感,相反人民币汇率对货币政策的反应相对较弱。     

Endogenous Money,Fiscal Policy,Interest Rates and the Exchange Rate Regime: Correction

This note suggests two corrections that might usefully be made to the analysis in an earlier article with the same title. The corrections have no direct bearing on the original argument (which had to do with disputes about modern money theory, or MMT) but do seem important for the future development of an alternative monetary theory.     

Monetary Policy and Exchange Rate Volatility in a Small Open Economy

We lay out a small open economy version of the Calvo sticky price model, and show how the equilibrium dynamics can be reduced to a simple representation in domestic inflation and the output gap. We use the resulting framework to analyse the macroeconomic implications of three alternative rule-based policy regimes for the small open economy: domestic inflation and CPI-based Taylor rules, and an exchange rate peg. We show that a key difference among these regimes lies in the relative amount of exchange rate volatility that they entail. We also discuss a special case for which domestic inflation targeting constitutes the optimal policy, and where a simple second order approximation to the utility of the representative consumer can be derived and used to evaluate the welfare losses associated with the suboptimal rules.     

Monetary Policy and Exchange Rate Interactions in a Small Open Economy

The transmission mechanisms of monetary policy in a small open economy like Norway are analysed through structural VARs, with special emphasis on the interdependence between monetary policy and exchange rate movements. By imposing a long‐run neutrality restriction on the real exchange rate, thereby allowing the interest rate and the exchange rate to react simultaneously to news, I find considerable interdependence between monetary policy and the exchange rate. In particular, following a contractionary monetary policy shock, the real exchange rate immediately appreciates, after which it gradually depreciates back to the baseline. The results are found to be consistent with findings from an “event study”.     

货币政策与财政政策的“新共识”

20世纪90年代以来,宏观经济政策领域出现了一种"新共识",近年来得到进一步发展。在"新共识"宏观经济模型中,货币存量不起作用,但货币政策被赋予非常重要的作用,货币政策可以决定通货膨胀;货币政策采用盯住通货膨胀的方式,通过调节利率将通货膨胀控制在一个较低的水平。财政政策在管理总需求水平方面仍然是一个强有力的工具,"新共识"宏观经济学体现了"货币主义与财政主义的综合"。     

Fiscal Policy and Exchange Rates

This paper examines the dynamics of the nominal exchange rate and fiscal deficits in a continuous time optimizing general equilibrium model with OLG. It is shown that alternative financing modes of budget deficits imply different patterns of adjustment along the transitional path towards the steady-state equilibrium. In particular, the respect of public solvency without money financing is not sufficient to avoid the depreciation of the exchange rate in the long-run after a fiscal expansion. In addition, money and tax financing generate opposite intergenerational reallocation of wealth.     

Exploring the Role of the Real Exchange Rate in Australian Monetary Policy

An important issue in small open-economies is whether policymakers should respond to exchange rate movements when they formulate monetary policy. Micro-founded models tend to suggest that there is little to be gained from responding to exchange rate movements, and the literature has largely concluded that such a response is unnecessary, or even undesirable. This paper examines this issue using an estimated model of the Australian economy. In contrast to microfounded models, according to this model policymakers should allow for movements in the real exchange rate and the terms-of-trade when they set interest rates. Further, taking real exchange rate movements into account appears even more important with price level targeting than with inflation targeting.     

Exchange Rates and Monetary Policy

This paper looks at the relation between exchange rates and monetary policy. It focuses in particular on the role of the exchange rate of the euro in the context of the ECB's monetary policy strategy. The objective of monetary policy is to maintain price stability. The euro area is a large and relatively closed economy. Therefore, the exchange rate of the euro is not an intermediate target nor is it an objective. Nevertheless, the ECB's stability–oriented monetary policy strategy does not neglect the exchange rate of the euro. Clearly, exchange rate developments are taken into account both when looking at the transmission mechanism of monetary policy and when assessing the current economic situation and prospects for the euro area.     

On the Effectiveness of Monetary Policy and of Fiscal Policy

There has been a major shift within macroeconomic policy over the past two decades or so in terms of the relative importance given to monetary policy and to fiscal policy in both policy and theoretical terms. The former has gained considerably in importance, with the latter being rarely mentioned. Furthermore, the nature of monetary policy has shifted away from any attempt to control some monetary aggregate (prevalent in the first half of the 1980s), and instead monetary policy has focused on the setting of interest rates as the key policy instrument. There has also been a general shift towards the adoption of inflation targets and the use of monetary policy to target inflation. This paper considers the significance of this shift in the nature of monetary policy. This enables us to question the effectiveness of monetary policy, and to explore the role of fiscal policy. We examine these questions from the point of view of the "new consensus" in monetary economics and suggest that it is rather limited in its analysis. When the analysis is broadened out to embrace empirical issues and evidence the clear conclusion emerges that monetary policy is relatively impotent. The role of fiscal policy is also considered, and we argue that fiscal policy (under specified conditions) remains a powerful tool for macroeconomic policy. This is particularly an apt conclusion under current economic conditions.     

Monetary and Fiscal Policy Rules in the EMU

Abstract. This paper studies the design and effects of monetary and fiscal policy in the euro area. To do so, a stylized two‐region model of monetary and fiscal policy rules in the EMU is built. We analyse how monetary and fiscal rules affect the adjustment dynamics in the model. Both the effects on the individual countries and on the EMU aggregate economy are studied. Three aspects play an important role in the analysis: (i) the consequences of alternative monetary and fiscal policy rules, (ii) the consequences of asymmetries between EMU countries (asymmetries in macroeconomic shocks and macroeconomic structures), and (iii) the role of alternative degrees of backward‐ and forward‐looking behaviour in consumer decisions and inflation expectations.

Interactions between Monetary and Fiscal Policy Rules

The Fiscal Stability Pact for EMU implies that constraints on fiscal policy facilitate inflation control. In this paper we identify two stable policy regimes. When monetary policy seeks to raise real interest rates in response to excess inflation, a self-stabilising fiscal policy is required to ensure model stability. A fiscal policy which does not, by itself, ensure fiscal solvency constrains monetary policy to be relatively 'passive'. However, in simulations we conclude that the central bank does not need to seek, on this account, the degree of debt stabilisation that appears to be implied by the fiscal stability pact.     

Some Fiscal Implications of Monetary Policy

We study the implications of alternative monetary targeting procedures for real interest rates and economic activity. We find that countercyclical monetary policy rules lead to higher real interest rates, higher average tax rates, lower output but lower variability of tax rates and consumption relative to procyclical rules. For a country with a high level of public debt (e.g. Italy), the adoption of a countercyclical procedure such as interest rate pegging may conceivably raise public debt servicing costs by more than half a percentage point of GNP. Our analysis suggests that the current debate on the targeting procedures of the European Central Bank ought to be broadened to include a discussion of the fiscal implications of monetary policy.     

Fiscal Policy,Monetary Policy and the Mechanics of Modern Clearing and Settlement Systems

Thomas Palley, Eric Tymoigne and Randall Wray recently debated neo-Chartalism in this journal. This article argues that the mechanics of modern clearing and settlement systems is important to understanding this debate. In the neo-Chartalist framework taxes and bond issuance function as part of monetary policy; it is an alternative method for draining reserves to obtain the overnight target rate. Abba Lerner’s Chartalist framework is much clearer on public finance, noting that the federal government can use alternative financing methods to pay for expenditures. Palley’s concerns with central bank ‘money financing’ and inflation are unpersuasive. The Old Keynesian ‘budget restraint– high-powered money relation’ offers limited insight into modern clearing and settlement systems. The article concludes that policymakers should embrace Lerner’s advice and view ‘money printing’ as a normal policy instrument to support functional finance.     

Fiscal Discipline and Exchange Rate Systems

A new 'fiscal' theory of price determination has implications for exchange rate systems and common currency areas. We show that deeper monetary integration requires the discipline of a Ricardian regime ; that is, the government must guarantee fiscal solvency for any sequence of prices or exchange rates. Particularly striking results are that a currency peg is not credible without the discipline of a Ricardian regime, and a common currency area is not viable if fiscal policy in two (or more) of the countries in the union is Non-Ricardian. Interestingly, constraints written into the Maastricht Treaty are sufficient for a Ricardian regime.
