FISCAL POLICY, MACROECONOMIC STABILITY AND FINITE HORIZONS

In this paper we analyse the stabilisation properties of distortionary taxes in a new‐Keynesian model with overlapping generations of finitely lived consumers. In this framework, government debt is part of net wealth and this adds a number of interesting channels through which fiscal policy could affect output and inflation. Output volatility, in the presence of technology shocks, is not substantially affected by the operation of automatic stabilisers, but we find interesting composition effects. While the presence of finitely lived households strengthens the stabilisation performance of distortionary taxes through the reduction of the volatility of consumption, it does so at the cost of more volatile investment and real money balances.     

MACROECONOMIC POLICY AND ELECTIONS IN OECD DEMOCRACIES*

The purpose of this paper is to test for evidence of opportunistic “political business cycles” in a large sample of 18 OECD economies. Our results can be summarized as follows: 1) We find very little evidence of pre-electoral effects on economic outcomes, in particular, on GDP growth and unemployment; 2) We see some evidence of “political monetary cycles,” that is, expansionary monetary policy in election years; 3) We also observe indications of “political budget cycles,” or “loose” fiscal policy prior to elections; 4) Inflation exhibits a post-electoral jump, which could be explained by either the pre-electoral “loose” monetary and fiscal policies and/or by an opportunistic timing of increases in publicly controlled prices, or indirect taxes.     

MONETARY POLICY REGIME SWITCHES AND MACROECONOMIC DYNAMICS*

This article considers the determinacy and distributional consequences of regime switching in monetary policy. Although switching in the inflation target does not affect determinacy, switches in the inflation response can cause indeterminacy. Satisfying the Taylor principle period by period is neither necessary nor sufficient for determinacy when inflation responses switch; indeterminacy can arise if monetary policy responds too aggressively to inflation in the active regime. Inflation target switches primarily impact the level of inflation, whereas inflation response switches primarily impact the volatility. Expecting an inflation target switch has minor effects on volatility, whereas expecting an inflation response switch raises volatility more substantially.     

OPTIMAL CONTRACTS FOR CENTRAL BANKERS AND PUBLIC DEBT POLICY*

We consider how the second‐best allocation corresponding to an optimal rule under the policy commitment of a central bank and a fiscal authority with a consolidated government budget constraint can be achieved, even though these authorities are unable to commit themselves to their optimal policies and ignore the strategic interaction between their policies. Our results show that the best practical institutional arrangement is to have an instrument‐independent central bank that controls the money supply to determine the rate of inflation and commits itself to an inflation target that depends on fiscal variables.     

PPP EXCHANGE RATE RULES,MACROECONOMIC (IN)STABILITY,AND LEARNING*

In order to maintain competitiveness, governments in developing economies seem to have pursued purchasing power parity (PPP) exchange rate rules, by adjusting the nominal devaluation rate in response to real exchange rate deviations from an intermediate target. This article shows that these rules are likely to induce macroeconomic instability, as they generate sunspot‐driven fluctuations that are in fact learnable by agents in the Expectational‐Stability sense. It finds that the existence of these “learnable sunspots” depends, among others, on open economy features, including the degree of openness and the degree of exchange rate pass‐through to consumer's import prices.     

货币政策、金融周期及其宏观经济效应

本文综合金融市场的多维信息,利用主成分分析法合成我国的金融周期指数。在此基础上,构建TVP SV VAR模型研究2003—2017年间我国货币政策、金融周期及宏观经济变量间的时变互动关系。研究发现：（1）我国货币政策、金融周期和宏观经济变量之间存在显著的时变互动关系。（2）金融传导渠道可能扭曲货币政策效力,通过金融传导渠道,货币政策不仅会抑制经济增长,还可能加剧通货膨胀。（3）金融周期对货币政策产出效应的影响滞后于对价格效应的影响。短期来看,货币政策产出效应的时变特征与金融传导渠道无太大关联,但随时间推移,金融繁荣对产出的负面影响可能最终使货币政策产出效应发生反转。货币当局应警惕金融繁荣对货币政策效力的扭曲,审慎操作,且不宜承担过多刺激产出的任务。     

成本冲击、通胀容忍度与宏观经济政策

与之前比较,2010年以来此轮通胀成本冲击型特征十分明显（主要表现为国际大宗商品价格高企和国内劳动力成本上升）。在此背景下,是否应提高对通胀的容忍度以及宏观政策如何有所作为已成为热门话题。目前国内外已经有一些对通胀容忍度的探讨,但规范性的研究论文并不多见。本文在多恩布什-费雪（Dornbusch Fischer）框架基础上,结合中国实际,创新性地区分大宗商品价格和劳动力成本冲击（尤其是B S效应）对总供给以及宏观经济的不同影响机制,探讨有关通胀容忍度以及宏观政策应对问题。     

宏观调控政策的国际互动及效应

通过运用格兰杰二元因果关系检验和协整检验等方法对多国的货币市场利率、货币供给量、政府净债务和政府支出等指标的增长率变动进行分析,可以证实国际间的货币政策和财政政策调控存在显著的互动关系,并且通过分析这些指标与各国经济总量GDP的互动关系,可以证实存在着国际间宏观经济互动调控的经济福利效应,它通过一些宏观经济调控政策的国际互动机制得以实现。     

FISCAL POLICY RULES AND THE SUSTAINABILITY OF PUBLIC DEBT IN EUROPE*

The sustainability of public debt is interpreted as the result of the interaction of fiscal policy with the economic environment, and not as a statistical concept as in most of the recent literature. If debt is not to explode over time, policymakers have to respond to the changing conditions in the macroeconomic environment. This article defines the conditions that will ensure compliance of fiscal policy with the intertemporal budget constraint in the context of Europe's fiscal policy rules. The empirical part of the article reveals that European public debt is sustainable in this respect, but questions regarding long‐run liquidity requirements remain unresolved.     

中国经济走势与宏观经济政策取向

本文采用历史分析和逻辑研究相结合的方法,认为中国经济的运行规律是决定中国未来宏观经济走势的基础,而世界经济运行规律和中国的宏观经济政策选择也影响着宏观经济的走势。无论从中国经济自身的运动规律还是从世界经济的运行规律来看,未来几年中国经济增长总体上都将呈现向好的趋势。因此,2012年及其未来一段时间,保持经济适度增长,促进结构调整,抑制通货膨胀,将成为中国经济发展的主旋律和政策选择的目标。     

SHORT-RUN MONETARY POLICY AND THE MACROECONOMIC ENVIRONMENT

This study investigates factors influencing monetary policy decisions of the Federal Open Market Committee (FOMC) over the period 1960–1998. Competing perspectives regarding the process of monetary policy making exist, with some researchers contending the FOMC makes short-run policy decisions based solely on "objective" macroeconomic considerations and others arguing that political and other nonmacroeconomic considerations significantly influence monetary policy voting. Empirical studies support both views in varying degrees. This article presents a model of FOMC decision making which posits that (1) the current/prospective macroeconomic environment at the time of FOMC meetings is the most important consideration of monetary policy makers, and (2) nonmacroeconomic variables receive little attention unless macroeconomic conditions are difficult for policy makers to assess. Probit results support the implications of the model.     

LINKAGES BETWEEN EXCHANGE RATE POLICY AND MACROECONOMIC PERFORMANCE

Using a sample of 104 countries, we study macroeconomic performance from 1973 to 2007. We examine GDP growth, inflation rate, growth volatility and inflation volatility, and their response to a ‘words versus deeds’ measure of exchange‐rate policy, which is obtained by interacting a country's de jure and its de facto policy. For non‐industrialized countries, the highest growth rates and the lowest inflation volatility are associated with countries that pursue fear of floating policy, whereas countries that pursue a matched float policy (de jure and de facto floating) have the highest inflation rates but the lowest GDP volatility.     

STRATEGIC DEBT AND RJV COMPETITION*

Firms first choose their debt level, next form an RJV and choose R&D investment, and then choose output in Cornot competition. Through the use of debt, a firm commits an aggressive stance, a higher output level, and higher R&D investment, whereby the latter helps solve the free‐riding problem that usually exists in R&D studies. However, a firm in an unleveraged industry gains the highest profit, while a leveraged firm in an asymmetric industry (which achieves the highest profit in Brander and Lewis (1988)) gains the lowest profit. As a result, both firms using debt and both firms not using debt are the two equilibria, and the latter survives as a focal outcome. This is in sharp contrast to Brander and Lewis who find that both firms using debt is a prisoner's dilemma outcome.     

中国宏观经济形势与政策2001-2002年

中国宏观经济政策应该遵循竞争性市场经济的均衡原则,并且其短期效应与长期效应应该是相互包容和内在一致的,短期的反周期需求管理在长期均衡的宏观经济政策框架下实现。中国经济需求管理的财政政策、货币政策、汇率政策长期组合应该是平衡财政预算、稳定货币供应与均衡汇率机制。     

MACROECONOMIC POLICY REFORMS AND PRODUCTIVITY GROWTH IN AFRICAN AGRICULTURE

This article employs a two‐stage procedure to investigate the impact of macroeconomic policy reforms on the agricultural productivity growth of 33 African countries from 1981 to 2001. In the first stage, we measure agricultural productivity using a nonparametric Malmquist productivity index. In the second stage, we build a generalized method of moments (GMM) model with a measure of structural adjustment program (SAP) intensity as a key instrument for macroeconomic policy reforms. We also control for the effects of globalization, civil violence, level of development of physical and financial infrastructure, and other economic variables as well as natural resource factors that directly affect agricultural productivity. Our results indicate a strong positive correlation between the extent of SAP intensity and agricultural productivity, suggesting that the macroeconomic policy reforms improved agricultural productivity growth in the sample countries.
