Customer Markets,Inflation and Unemployment in a Dynamic Model with a Range of Equilibria

The paper presents a dynamic model incorporating a range of non‐accelerating‐inflation rates of unemployment (NAIRU) obtained according to the theoretical framework proposed by the customer markets literature. The analysis of the dynamic adjustments of unemployment and inflation emphasizes the real effects of demand shocks. Changes in the fiscal and monetary policy can exert permanent effects on output and unemployment, both determining persistence in the unemployment rate and selecting the actual steady‐state equilibrium within the NAIRU range.     

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?     

中国经济增长中货币政策与财政政策有效性的比较检验

本文通过一个广义货币供应量、财政支出和国内生产总值三变量向量误差修正模型(VECM)考察中国1978—2005年间货币政策和财政政策对经济增长影响的差异性特征。在应用脉冲响应函数和方差分解方法研究它们之间的动态特性后发现:积极货币政策的经济增长效果无论在短期还是长期内均要强于财政政策,长期内,积极货币政策对经济增长一直有递减的正效应,但是积极财政政策由于挤出效应的影响,长期内对经济增长呈负效应。     

当前我国宏观经济下的财政政策

财政政策与货币政策是调控宏观经济的两种最重要手段,为了保障宏观经济平稳的运行,在实际的经济生活中适时、适当地运用财政政策与货币政策十分重要。伴随着我国改革开放的进行,财政政策在我国的经济中起着越来越重要的作用。财政政策根据稳定经济的需要,通过财政支出与税收政策来调节总需求,增加政府支出,可以刺激总需求,从而增加国民收入,反之则压抑总需求,减少国民收入。     

Monetary Dynamics of Inflation in China

This paper investigates both the short‐run and the long‐run relationships between monetary growth and inflation in China between 1980 and 2010. We construct multivariate dynamic models based on Friedman’s quantity theory of money (but permitting money to be endogenous) and Meltzer’s monetarist model. The empirical results provide robust evidence that there is a bilateral causal relationship between monetary growth and inflation as well as between monetary growth and output growth. An indirect and implicit causal relationship between monetary growth and inflation is found through the asset inflation channel. There are also long‐run equilibrium relationships between money stock, price index and other relevant variables. The present paper further provides a historical exploration of the mechanism of the monetary dynamics of inflation in China over the underlying period. We conclude that the monetary growth rule is likely to be the most promising policy orientation for China to manage its inflation.     

Fiscal and Monetary Policy Rules in an Unstable Economy

This paper examines the implications of different monetary and fiscal policy rules in an economy characterized by Harrodian instability. We show that (1) a monetary rule along Taylor lines can be stabilizing for low debt ratios but becomes de‐stabilizing if the debt ratio exceeds a certain threshold, (2) a ‘Keynesian’ fiscal policy rule can stabilize the economy at full employment, (3) a fiscal ‘austerity’ rule that links fiscal parameters to deviations from a target debt ratio fails to adjust the ‘warranted’ to the ‘natural’ growth rate and destabilizes the warranted path and (4) instability may arise from a combination of fiscal and monetary policy rules which separately would stabilize the system.     

A POST‐KEYNESIAN AMENDMENT TO THE NEW CONSENSUS ON MONETARY POLICY

A common view is now pervasive in policy research at universities and central banks, which one could call the New Keynesian consensus, based on an endogenous money supply. This new consensus reproduces received wisdom: in the long run, expansionary fiscal policy leads to higher inflation rates and real interest rates, while more restrictive monetary policy only leads to lower inflation rates. The paper provides a simple four‐quadrant apparatus to represent the above, and it shows that simple modifications to the new consensus model are enough to radically modify received doctrine as to the likely effects of fiscal and monetary policies.     

Can monetary policy tame Harrodian instability?

The paper introduces monetary policy into the canonical Kaleckian growth model with a built‐in Harrodian instability. It abstains, however, from the simple and immediately stabilizing interest rate inverse IS curve. Instead, more indirect effects are examined, which realistically will take time to work out. In particular, (a) the trend rate of growth governing the investment decisions additionally responds to the difference between the profit rate and the real rate of interest; and (b) the real interest rate may enter dynamic adjustments of the price markup. The main finding is that the Harrodian forces could still be overcome and stability of the steady state position is re‐established provided that the profitability motive in (a) and the responsiveness in the Taylor policy rule are both sufficiently strong. By contrast, the indirect feedback effects produced by (b) broaden the scope for instability. In sum, monetary policy in this extended framework can favour stability but is not necessarily the stabilizing panacea that the New Consensus considers it to be.     

财政政策对经济增长与价格波动影响的动态效应研究——结合货币供给量的SVAR分析

通过建立结构式向量自回归模型(SVAR),就财政政策对经济增长和价格水平的动态效应作深入分析。结果表明,财政支出对经济增长影响波动较大,中长期总体效应为正面影响。而在加入货币政策变动影响后,它对经济增长在中长期效应为负面影响,货币供给总体表现为正面影响,两者对经济增长的综合影响为正。     

A POST‐KEYNESIAN STOCK‐FLOW CONSISTENT MODEL FOR DYNAMIC ANALYSIS OF MONETARY POLICY SHOCK ON BANKING BEHAVIOUR

We try to make Keynes' approach compatible with an endogenous theory of the money supply. For that purpose, the principle of liquidity preference is generalized within a competitive banking framework. Private banks can impose a monetary rationing independently of the central bank. Then, we analyse the consequences of a monetary policy shock on the financial behaviour of banks. We clarify the dynamic process between the monetary policy and net investment within a Minskyan approach. First, we build a Post‐Keynesian stock‐flow consistent model with a private‐bank sector introducing more realistic features. Second, we perform some simulations.     

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.

宏观政策的协调机制与欧洲债务危机

通过政策调整损失函数的理论模型分析,认为负的需求冲击是构成欧洲债务危机的前提,而缺乏货币政策协调的持续性扩张财政政策是欧洲债务危机的本质原因。对2000Q1—2010Q1的"PIIGS"的季度数据进行实证分析后,发现5国独立财政政策和欧元区共同货币政策的协调机制是存在冲突的。希腊长期均衡和短期调整均存在主权债务危机风险,因而成为首个爆发危机的国家。西班牙、意大利的短期调整虽暂时缓解了主权债务危机出现的可能,但不能解决发生危机的根本问题。而爱尔兰、葡萄牙只是短期内实施了过度的积极财政计划而造成了主权债务危机假象。     

政策协调、产业结构升级及宏观经济效应分析

不同模式的宏观政策协调不但会对产业结构优化产生差异性影响,也会影响产业结构优化带来的宏观经济效应。本文在新凯恩斯框架下构建理论模型,并基于贝叶斯参数估计和数值模拟分析政策协调对产业结构优化以及宏观经济效应的影响。研究发现:数量型货币政策比价格型货币政策更有利于产业结构优化,收入型财政政策比支出型财政政策更有利于产业结构优化;价格型货币政策和收入型财政政策的政策协调更有利于产业结构优化对消费、就业和产出的促进作用,数量型货币政策和支出型财政政策的政策协调更有利于产业结构优化对通货膨胀的稳定作用;货币政策对产业结构优化升级这一目标与稳定经济波动这一目标存在着Trade Off现象,财政政策对产业结构优化升级这一目标与促进经济增长这一目标存在着Trade Off现象。因此,建议采取货币政策为主、财政政策为辅的宏观经济调控政策,具体操作体现在减息为主结合降低税率水平为辅的政策协调组合来应对经济增速下滑和产业结构升级。     

Symbiosis of monetary and fiscal policies in a monetary union

We consider the interaction between the monetary policy in a monetary union, and the separate fiscal policies of the member countries. We use a Barro–Gordon-type model extended to many countries and fiscal policies. Each country’s fiscal policies inflict externalities on other countries, and the common monetary policy has its time-consistency problem. But if the two types of policymakers agree about the ideal levels of output and inflation, then this ideal is attained despite disagreements about the weights of the objectives, despite ex post monetary accommodation to fiscal profligacy, without fiscal coordination, without monetary commitment, and for any order of moves.     

中国积极财政政策与货币政策效力的比较——对蒙代尔—弗莱明模型的一个修正运用

运用一个修正的MF模型 ,对我国积极财政政策和货币政策的效力进行比较 ,得出在我国现行汇率制度安排下 ,积极财政政策的效果要优于货币政策。当前我国的经济政策应以财政政策为主 ,坚持积极的财政政策 ,淡化扩张性的货币政策。     

财政货币政策在宏观调控中的协调配合

在财政政策与货币政策之间存在一些结合部,深入研究这些结合部对于充分发挥财政货币政策作用,减少政策摩擦,具有重要意义。本文认为,我国政府已经能够根据宏观经济形势的需要主动选择适当的政策组合,运用间接手段调节供求关系,并初步建立了适应市场运行机制的宏观调控体系。文章强调,财政货币政策的协调配合一直是宏观调控的核心问题之一,随着我国政府“财政货币双稳健”宏观调控思想的确立,两大政策的协调配合将从以总量调控为主转向以结构或制度配合为主。     

Demand-side stabilization policies: What is the evidence of their potential?

Using disaggregated data for the United States, this paper explores the effects of the variability of fiscal and monetary policy shocks. Higher variability of government spending shocks around a steady-state growth trend results in, on average, a decline in aggregate demand growth and inflation, with limited effects on output growth. On the other hand, higher variability of monetary shocks results in, on average, an increase in inflation and a decline in output growth. These results indicate the desirability of avoiding large fluctuations over time in either government spending or the money supply.     

RE‐EXAMINING THE IMPLICATIONS OF THE NEW CONSENSUS: ENDOGENOUS MONEY AND TAYLOR RULES IN A SIMPLE NEOCLASSICAL MACRO MODEL

This paper re‐examines the impact of endogenous money in a neoclassical model with interest‐sensitive expenditures. It first outlines a benchmark model with exogenous money and the usual full employment and money growth‐determined inflation results. It then replaces exogenous money with endogenous money, which is shown to generate model indeterminacy. Two methods of resolving this indeterminacy are then explored: money illusion and a Taylor rule for monetary policy, a key feature of new consensus models. The paper concludes that endogenous money has negative implications for the behaviour and interpretation of neoclassical and new consensus models.     

ENTRY AND EXIT OF FIRMS AND UNDEREMPLOYMENT EQUILIBRIUM

This paper extends the standard Keynesian model of aggregate demand and supply allowing for imperfect competition, variable returns to scale, and entry and exit of firms. It distinguishes three phases of macroeconomic equilibria, stagnant, expansive and contractive, according to whether the number of firms is fixed or endogenously determined by the position of the aggregate demand curve. Using this model we show that a large shift in the aggregate demand affects the structure of the economy irreversibly and that the real wage or labor productivity may move procyclically rather than anticyclically. We also elucidate the asymmetric effects of fiscal and monetary policies on the entry of firms and employment.
