一般均衡中的利率、确定性与最优规则

利率规则理论是以短期利率作为货币政策工具而发展起来的一套新的理论,它体现了货币经济学家在货币政策领域内的新的尝试和努力。在利率规则理论中,货币经济学家试图解决两个问题:利率规则冲击对非政策经济变量的短期影响是什么,以及一个好的利率规则应当具有怎样的性质。利率规则将短期利率作为非政策经济变量的内生反应函数,使得货币经济学家可以在一般均衡模型中探讨这两个问题。然而,由于利率规则从一开始就是出于一种偏好的设定,因此,讨论的结果并不符合稳健性和科学性的要求,这就削弱了理论预言的可靠性。在某种意义上,利率规则理论若想成为一门真正的"科学的艺术",它就必须为内生利率规则寻找到一个坚固的微观基础。本文梳理评述了利率规则理论在经验上和理论上的成就和不足。     

Effectiveness of Monetary Policy in Euroland

In this paper we analyze the effects of different decision rulesin the ECB on monetary stability. We consider a model where asymmetricshocks and divergent propagation of shocks on output and inflation arepotential causes of tension within the ECB concerning the conduct ofmonetary policy. Given divergence of desired interest rates we analyze theeffect of different voting procedures within the Governing Council of theECB. We find that under ECB-rule the ECB Board is able to impose its desiredinterest rate as the Euro-wide interest rate. Large countries benefit fromECB-rule as it implies higher voting power for them at the GoverningCouncil. Our welfare analysis indicates that under particular parameterspecifications ECB-rule is strictly preferred to Nationalistic rule.     

Interest rate rules, inflation and the Taylor principle: an analytical exploration

Summary. The purpose of this article is to characterize optimal interest rate rules in the framework of a dynamic stochastic general equilibrium model, and notably to scrutinize the “Taylor principle”, according to which the nominal interest rate should respond more than one for one to inflation. This model yields explicit solutions for the optimal rule. We find that the elasticity of response depends on numerous factors, such as the degree of price rigidity, the autocorrelation of the underlying shocks, or which measure of inflation is used. In general the optimal elasticity of the interest rate with respect to inflation needs not be greater than one.Received: 6 November 2003, Revised: 17 August 2004 JEL Classification Numbers: E5, E52, E58.J.-P.

中国货币政策规则稳健性研究——基于不确定性视角

通过中国货币政策规则的统计特征和调整模式研究中国货币政策规则的稳健性以及不确定性,结论表明:中国货币政策调整规则基本符合调整频率低、每次调整幅度小、反转调整次数少且在长时间静止之后再进行反转调整的稳健性特征,除此之外,声誉不确定性也是导致中国货币政策规则稳健性特征的主要原因之一.     

Determinacy, stock market dynamics and monetary policy inertia

We study equilibrium determinacy in a New-Keynesian model where the Central Bank responds to asset prices growth. Unlike Taylor-type rules that react to asset prices, the proposed alternative does not harm dynamic stability and in certain cases promotes determinacy by inducing interest-rate inertia.     

中国特色社会主义市场经济货币政策体系的形成及演变*

伴随中国特色社会主义基本经济制度的发展,与之相适应的宏观调控机制不断完善。货币政策体系作为其中重要组成部分,在持续深化改革的进程中逐渐演进,成为构建更加系统完备、更加成熟定型的高水平社会主义市场经济体制的重要内容。在货币政策最终目标及中间目标、货币政策工具、货币政策传导机制等方面正在形成与中国特色社会主义基本经济制度相适应的政策体系,并且具有鲜明的中国特色。本文讨论改革开放以来中国货币政策体系的形成、演变过程及特点。

Investment,interest rate rules,and equilibrium determinacy

Summary. By adding endogenous investment to a flexible-price, money-in-the-utility-function model, this paper studies the role that physical capital plays in stabilizing the real side of the economy when the monetary authority follows interest-rate feedback rules. We show that with inelastic labor supply equilibrium uniqueness is ensured under both active and passive monetary policies. For the case where money affects both preferences and technology, the uniqueness result remains true under active monetary policy. With endogenous labor supply, the uniqueness result holds again regardless of the stance of monetary policies for the case with separable leisure, but indeterminacy remains likely under both active and passive monetary policies when leisure is nonseparable.Received: 19 December 2001, Revised: 12 May 2003, JEL Classification Numbers: E52, O42.We are grateful to Jess Benhabib and an anonymous referee for helpful comments and suggestions.

略论中国货币政策有效性

在界定货币政策有效性的概念基础上对中国的货币政策效果进行实证分析,进而提出提高中国货币政策有效性的对策建议。货币政策目标的实现程度是衡量货币政策有效性的标志。货币政策有效性的内涵就是货币政策具有真实效应,能够对真实经济变量产生影响。货币政策有效性就是货币政策能够在保持物价稳定、国际收支平衡的前提下促进经济增长和降低失业。     

析货币政策的科学性与艺术性

货币政策的制定和实施离不开科学原则作指导,但货币政策的实时决策又是极其复杂的,需要中央银行家的审时度势和敏锐判断,也即货币政策的艺术性。详细分析了货币政策科学性和艺术性的具体表现,认为货币政策的科学性与艺术性在实践中是难以分割和同等重要的,好的货币政策总是需要好的政策实施者,需要将科学性原则与中央银行家们的决策艺术完美地结合起来。

The Doctoral Origins of Economics Faculty and the Education of New Economics Doctorates

For the open economy, the workhorse model in intermediate textbooks still is the Mundell-Fleming model, which basically extends the investment and savings, liquidity preference and money supply (IS-LM) model to open economy problems. The authors present a simple New Keynesian model of the open economy that introduces open economy considerations into the closed economy consensus version and that still allows for a simple and comprehensible analytical and graphical treatment. Above all, their model provides an efficient tool kit for the discussion of the costs and benefits of fixed and flexible exchange rates, which also was at the core of the Mundell-Fleming model.     

货币信贷运行特点与货币政策操作取向

本文回顾了2009年中国货币政策操作的主要措施,说明了2009年金融运行情况和特征,分析了2010年货币政策运行环境,提出了货币政策建议。本文认为,2009年,为了应对国际金融危机的不利影响,中国人民银行实行了适度宽松的货币政策,货币环境宽松,有力地支持了经济企稳回升。2010年,随着经济形势的变化,中国人民银行需要在保增长、调结构和防风险之间取得平衡,因此需要在保持货币政策的连续性和稳定性的同时,进一步增强货币政策的前瞻性、针对性和灵活性,保持货币信贷的合理均衡增长,促进经济稳定发展。
