发展循环经济与政府职能转变

传统计划经济体制下的政府职能不能适应循环经济发展的需要。作为一种健康的经济发展模式,在社会主义市场经济下发展循环经济要求转变政府职能、加强政府的支持和调控能力,实现政府行为的规范化和高效化;同时,为保证循环经济顺利发展,政府要充分利用财政政策、金融政策和产业政策,加大政府对循环经济的宏观调控力度。     

Trade,money and employment in intertemporal optimizing models of growth

This paper unites elements of Sidrauski's (1967) monetary model of growth, Ventura's (1997) analysis of the effects of international trade on growth, and some work on the labour market implications of growth by Barro and Sala-i-Martin (1995). It was shown by Ventura that, for a small economy, free international trade leads to an increase of the de facto elasticity of substitution between the domestic factors of production. The first part of the paper analyses how such an increase in the elasticity of substitution influences the steady state and the speed of convergence. From the Sidrauski model we know that money is super-neutral in the long-run but that monetary policy can have real effects along the transition path as long as the intertemporal elasticity of substitution is not equal to one. In the second part of this paper, it is shown how these results also depend on the elasticity of substitution between factors of production. The results give some important insights into possible interactions between monetary and trade policy in the long and short run. The last part of the paper deals with a modified version of the monetary growth model, which includes endogenous labour supply as in Klump (1993) or Barro and Sala-i-Martin (1995). In this context, international trade, by increasing the elasticity of substitution, leads to lower domestic employment in the long run whereas monetary policy may be able to increase employment at least in the short run. Thus, under certain circumstances, trade and monetary policy can be regarded as complementary with respect to their labour market effects.     

信贷机制、货币乘数与货币政策有效性研究

本文在蒙代尔—弗莱明的分析框架下引入商业银行信贷机制,来考察固定汇率制下小型开放经济体货币政策的有效性问题,发现货币政策可以作为稳定经济的工具。文章指出,实行固定汇率制度的小型开放经济体,其货币政策具有一定的独立性,可以对实际产出产生一定的作用;不同的货币政策工具对实际产出发生作用的传导机制不同,从而导致效果不同,因此货币当局在对宏观经济进行调节时必须选择适当的货币政策工具。     

MONETARY AND FISCAL INTERACTIONS: SHORT‐RUN AND LONG‐RUN IMPLICATIONS

We model policy interactions in a growing economy. Unemployment can persist and matters for the real wage; conflicting claims underpin inflation outcomes; and aggregate demand determines capacity utilization and unemployment. Monetary policy is characterized by a Taylor rule. Fiscal policy is characterized by a marginal tendency to run deficits or surpluses. We address three questions: can monetary policy ensure macroeconomic stability in the absence of coordinated fiscal policy, can fiscal policy ensure macroeconomic stability when the monetary authority pegs the interest rate, and can policy authorities trade‐off some sustained inflation for a long‐run improvement in unemployment rates?     

Monetary and fiscal policy interactions in a micro-founded model of a monetary union

This paper analyzes in detail the mechanisms behind fiscal stabilization policy and the role of policy commitment in a micro-founded New-Keynesian model of a two-country monetary union, which is hit by supply shocks. We also explore the determinants of the gains from fiscal stabilization. While monetary policy with identical union members is concerned with stabilizing the union-wide economy, fiscal policy aims at stabilizing inflation differences and the terms of trade. Besides exploring optimal policies, we also consider monetary and fiscal rules. We study these rules both under coordination and non-coordination by the fiscal authorities.

MONETARY POLICY WITH INVESTMENT–SAVING IMBALANCES

Financial instability is the new challenge for monetary policy. Most studies indicate that financial crises follow prolonged unwinding of investment–saving imbalances (ISI). These phenomena are not contemplated by the standard theoretical framework of continuous intertemporal equilibrium. This paper's aim is to take a first step into the analysis of monetary policy in the context of ISI. First, a dynamic model of a flex‐price, competitive economy is presented where ISI are allowed to develop. Second, upon introducing different types of Taylor rules, some indications for the conduct of monetary policy emerge, which are at variance with the standard view.

货币政策对资本市场的非线性效应——基于自私募股权投资经验证据的分析

私募股权投资是资本市场的重要组成部分,而资本市场波动对宏观经济周期有重要影响。通过构建非线性计量经济模型,本文从不同期限结构和类型的政策模式角度探索货币政策对私募股权投资的非线性影响。研究发现,短期数量型货币政策在经济高涨时期对私募股权投资的调控效果更佳,而长期数量型货币政策在经济平稳时期对私募股权投资的调控效果更佳,数量型货币政策对私募股权投资的影响在时间维度呈现递减趋势;短期价格型货币政策在经济萧条时期对私募股权投资的调控效果更佳,而长期价格型货币政策在经济平稳时期对私募股权投资的调控效果更佳,价格型货币政策对私募股权投资的影响在时间维度呈现递增趋势。因此,长期价格型货币政策是我国进入经济新常态时期后的主要选择。     

Japanese economy and the its exchange rate from 1985 to 2010

The paper tries to analyze the interaction between Japanese exchange rate and its domestic economy from 1985 to 2010. By employing the Mundell-Fluming model, the paper is designed to shed light on the factors that determined the exchange rate and the impact of the exchange rate oa the economy, the theoretical resalt of the model will be enhanced with the help of graphs and statistical ambers, by the end of the paper; it concludes the important policy implication for the monetary policy and exchange rate policy.

Doing business in South Africa

This survey of the South African business environment outlines the major transformations the country has experienced since 1994. The economy has been restructured, which enhanced fiscal and monetary discipline as well as domestic and global competitiveness. The general business climate has been improved, but continued progress requires (1) prioritization of social issues such as HIV/AIDS, employment, and crime and (2) accelerated privatization, market reforms, and clarity about black economic empowerment. Such changes may stimulate inflation‐rate reduction, foreign exchange stability, and an increase in foreign direct investment. © 2004 Wiley Periodicals, Inc.     

不完全汇率传递下的货币政策工具规则分析

本文尝试构建一个开放条件下的总供给-总需求模型,通过名义进口价格刚性在模型中引入汇率传递因素。模型对各种货币政策工具规则下社会福利损失函数进行比较,考察在不同的汇率传递程度下的各种货币政策工具规则。研究结果显示,社会福利水平随着汇率传递程度下降而提高;货币政策工具规则对消费者物价指数(CPI)上涨作出反应一定程度上优于对国内制造商品价格上涨作出反应,制定的货币政策工具规则应该以CPI为目标,以使社会福利损失最小。     

中国货币政策非对称效应分析

经典的货币政策非对称效应意味着相同程度紧缩性货币政策效果显著强于扩张性货币政策,本文通过构建四类货币供给方程全面测度中国货币政策冲击,藉此验证货币政策非对称效应的存在性及表现形式。研究表明中国货币政策存在显著的非对称效应,当期正向货币冲击对产出的影响力度大于负向货币冲击对产出的影响力度;但滞后两期和四期负向货币冲击对产出的影响力度则分别大于相应滞后期的正向货币冲击的影响力度;考虑货币政策发挥作用的整个时段,紧缩性货币政策比扩张性货币政策更为有效。

随着以金融为核心的符号经济的不断发展 ,货币政策的传导机制变得日趋复杂 ,由此产生的一个问题是 ,货币政策是否需要把包括金融资产价格在内的广义价格指数作为调控目标。通过分析可知对于一个证券市场波动可能对宏观经济稳定产生重大影响的经济体而言 ,货币政策应该对资产价格变动保持密切关注 ,但不宜作为货币政策的调控目标     

浅议美国量化宽松货币政策背景下我国的经济对策

为应对金融危机带来的经济衰退,美国政府采用了量化宽松的货币政策,对全球经济产生了深远的影响,对我国经济的影响同样不可忽视。美国的量化宽松政策一方面导致我国出现严重的输入性通胀,另一方面迫使人民币升值压力加剧。更为严重的是我国的货币政策陷入到两难的境地。为了应对美国这一政策,我国需要全面运用货币政策、财政政策、收入政策、产业政策等政策组合,避免成为美国货币政策的牺牲品。同时以此为契机,加快我国经济结构调整和收入分配体制改革,并积极推进人民币国际化。     

Can monetary policy survive policy model mis‐specification? Model uncertainty and the perils of “policy model complacency”

The question addressed in this paper is: can monetary policy succeed in stabilizing the economy even when the policy model on which it is predicated is mis‐specified? Using variants of the 3‐equation macroeconomic model, it is shown that this question can be answered in the affirmative. The purpose of the paper is not to encourage indifference toward model uncertainty, however, but rather to warn against the perils of “policy model complacency.” This arises if the success of policy is misinterpreted as successful understanding of the workings of the economy, which makes the policy maker vulnerable to surprises: events with systematic origins in the “true” model of the economy that are not anticipated by the (mis‐specified) policy model. To safeguard against this problem, policy makers should always entertain eclectic views of the workings of the economy. This task is easily accomplished by paying attention to heterodox macroeconomics, which frequently makes predictions that are very much at variance with those of the dominant policy model.     

Optimal monetary and fiscal policy in a currency union

We lay out a tractable model for the analysis of optimal monetary and fiscal policy in a currency union. The monetary authority sets a common interest rate for the union, whereas fiscal policy is implemented at the country level, through the choice of government spending. In the presence of country-specific shocks and nominal rigidities, the policy mix that is optimal from the viewpoint of the union as a whole requires that inflation be stabilized at the union level by the common central bank, whereas fiscal policy has a country-specific stabilization role, one beyond the efficient provision of public goods.     

Open Economy Dynamics in a Floating Exchange Rate Developing Country Context

ABSTRACT

This article develops a wavelet-based control model to simulate fiscal, monetary, and real exchange rate scenarios in an open economy developing country with an inflation-targeting regime. We use South African macro data to jointly simulate optimal fiscal and monetary policy under varying scenarios for real exchange rate stability with interest rate parity. As real exchange rate stability increases, the model simulates the effects on the trade balance under both a constant and depreciating real exchange rate. We find that short-term cycle stability problems are somewhat mitigated by allowing the real exchange rate to depreciate.     

Financial Stability and the Hemianopsia of Monetary Policy

Financial stability concerns cannot be separated from macroeconomic objectives of monetary policy. Stimulative monetary policy works by creating financial conditions that could lead to instability in markets that could, in turn, engender deflationary pressures. Although the Federal Reserve Act does not explicitly mention financial stability as an FOMC objective, it is fundamentally bound together with the achievement of the explicit goals of maximum employment and price stability.
