货币政策对住宅商品房价格影响的区域差异——来自我国31省份的证据

我国房地产市场的发展演进与我国宏观经济走向有着密切的关系。由于我国不同地区间经济发展水平各异，经济运行特点有别，我国区域住宅商品房市场价格与宏观经济的联动关系以及对货币政策的反应效力均呈现出了明显差异。本文根据我国31省份的相关宏观数据，通过VAR/PVAR模型及统计学方法，研究发现了能够解释各区域住宅商品房价格趋势被持续维持的“正螺旋反馈机制”及货币政策的时滞效应。基于此，可将全国各省份的住宅商品房价格趋势的形成类型划分为货币政策主导型、经济增长主导型、混合主导型与房地产主导型。     

Real wage rigidities and optimal monetary policy in a small open economy

The main objective of the study is to provide a theoretical analysis of optimal monetary policy in a small open economy where households set real wage in a staggered fashion. The introduction of real wage rigidities plays a important role to resolve main shortcomings of the standard new Keynesian small open economy model. The main findings regarding the issue of monetary policy design can be summarized as three fold. First, the optimal policy is to seek to minimize variance of domestic price inflation, real wage inflation, and the output gap if both domestic price and real wage are sticky. Second, controlling CPI inflation directly or indirectly induces relatively large volatility in output gap and other inflations. Therefore, both CPI inflation-based Taylor rule and nominal wage-inflation based Taylor rule are suboptimal. Last, a policy that responds to a real wage inflation is most desirable.     

Money growth,uncertainty and macroeconomic activity: a multivariate GARCH analysis

The impact uncertainty has on money growth has received much attention in recent years and is an issue of critical importance to central banks, particularly for those, such as the European Central Bank (ECB), which place a strong emphasis on monetary analysis in monetary policy formulation. Some recent papers examining this issue use ad hoc estimates and measure variability rather than uncertainty. We employ a multivariate GARCH model, which measures uncertainty by the conditional variance of the data series, to investigate whether macroeconomic uncertainty and monetary uncertainty Granger-cause changes in real money. The estimated model also allows us to investigate how monetary uncertainty impacts economic activity. We find that macroeconomic uncertainty impacts positively on US real M2 growth over a two-year horizon but that monetary uncertainty does not cause changes in real M2. Instead, our results indicate that real money growth causes monetary uncertainty. Monetary uncertainty is found to have a negative effect on real economic activity and on macroeconomic uncertainty. We conclude by discussing the implications of these results and the methodological approach used for institutions such as the ECB that give monetary analysis a prominent role in their monetary policy strategy.     

Macroeconomic dynamics in Macedonia and Slovakia: Structural estimation and comparison

This paper estimates a structural macroeconomic model using data for Macedonia and Slovakia to characterize possible challenges Macedonia can face concerning macroeconomic stabilization during its transition process. A comparison of the estimated model parameters suggests that, in Slovakia, the output gap is less sensitive to real interest rate movements and prices experience greater inertia. The estimated monetary policy reaction functions show Macedonia and Slovakia as inflation targeters, with Macedonia as the more conservative one, despite its officially applied exchange rate targeting regime. The differences in the estimated parameters imply differing transmission mechanisms for Macedonia and Slovakia. Consequently, the variance of domestic variables in Slovakia is most influenced by monetary policy shocks, while there is no single dominating shock explaining the volatility of Macedonia's macroeconomic variables. The exchange rate shock, the monetary policy shock and the demand shock are jointly important in determining the volatility of Macedonia's variables. The model simulations indicate that Macedonia experiences lower output gap and inflation volatility than Slovakia. This comes, nevertheless, at the cost of higher interest rate and real exchange rate volatility in Macedonia, which could be an indication of more volatile financial markets with possible negative implications for financial stability.     

Monetary transmission mechanism in Turkey under the monetary conditions index: an alternative policy rule

This study analyses monetary transmission mechanism in Turkey using a small structural macroeconomic model. The core equations of the model consist of aggregate demand, wage-price setting, uncovered interest rate parity, foreign sector and a monetary policy rule. The aim of the paper is to analyse the disinflation path, the output gap, the output level, the exchange rate and the interest rate, and also the output–inflation variance frontier of the economy under various scenarios. The first scenario assumes that a standard Taylor rule is implemented as the policy rule. In the alternative scenario, instead of the standard Taylor rule, the MCI, Monetary Conditions Index – combination of the changes in the short-term real interest rate and in the real effective exchange rate in a single variable – is used as a policy instrument. The results indicate that the economy stabilizes much more quickly and shows significantly less volatility under this new setting. Therefore, the paper concludes that the policymakers should consider using MCI as an instrument when conducting monetary policy.     

The transmission mechanism of Malaysian monetary policy: a time-varying vector autoregression approach

The aim of this paper is to determine whether the propagation and transmission mechanism of Malaysian monetary policy differed during the Asian Financial Crisis of 1997/1998 and the Global Financial Crisis of 2007/2008. The methodology employs a time-varying vector autoregression framework. The primary result is that despite having no evidence of time-variation within the propagation mechanism of Malaysian monetary policy the average contribution of a monetary policy shock to the variability of each macroeconomic variable: real GDP, inflation and the nominal effective exchange rate, differs between the two crises. This finding suggests that despite the propagation mechanism being relatively constant, Malaysia’s monetary policy transmission mechanism evolves over time. We believe that the main mechanism driving this evolution is the time-variation in the variance–covariance matrix of the shocks of the model, not the coefficients. We also find some evidence that the implementation of capital controls reduced the influenceability of monetary policy on the Malaysian economy.     

Monetary policy, oil shocks, and TFP: Accounting for the decline in US volatility

An equilibrium model is used to assess the quantitative importance of monetary policy for the post-1984 decline in US inflation and output volatility. The principal finding is that monetary policy played a substantial role in reducing inflation volatility, but a small role in reducing real output volatility. The model attributes much of the decline in real output volatility to smaller TFP shocks. We also investigate the pattern of output and inflation volatility under an optimal monetary policy counterfactual. We find that real output volatility would have been somewhat lower, and inflation volatility substantially lower, had monetary policy been set optimally.     

Examining asymmetries in the transmission of monetary policy in the euro area: Evidence from a mixed cross-section global VAR model

I estimate the transmission of a common euro area monetary policy shock across individual euro area economies. To do so, I develop a global VAR model in which all euro area economies are included individually while, at the same time, their common monetary policy is modelled as a function of euro area aggregate output growth and inflation. The results suggest that the transmission of monetary policy across euro area economies displays asymmetries, and that, in line with economic theory, these are driven by differences in economies׳ structural characteristics. In particular, euro area economies in which a higher share of aggregate output is accounted for by sectors servicing interest rate sensitive demand exhibit a stronger transmission of monetary policy to real activity. Similarly, even though the evidence is less conclusive, euro area economies which feature more real wage and/or fewer unemployment rigidities also appear to display a stronger transmission of monetary policy to real activity.     

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.

Endogenous monetary policy and the liquidity effect

We compare the transmission mechanism of exogenous and endogenous monetary policies in a calibrated small open economy model with nominal and real rigidities. Under an exogenous monetary policy rule it takes implausible values of the intertemporal elasticity of substitution and the price adjustment costs to generate the liquidity and overshooting effects. Endogenous rules with strong feedback to inflation and output help to reproduce the response of the nominal interest and exchange rates to unanticipated monetary policy shocks that characterize the transmission mechanism of standard sticky price models. The liquidty and overshooting effects are always obtained when the model is augmented with a Taylor interest rate rule.JEL Classification: E32, E43Javier Andrés acknowledges support of CICYT grant SEC2002-0026.

Imperfect credibility,sticky wages,and welfare

This paper studies optimal monetary policy under imperfect credibility in a New Keynesian model with staggered price and wage setting. In our imperfect credibility framework, the central bank commits to a policy plan but occasionally reneges on past promises with a given common knowledge probability. We find that the welfare gains from increasing credibility are approximately linear on the initial credibility level. We also find that the output-inflation stabilisation trade-off is nonmonotonic as higher credibility does not always reduce output volatility. The variance decomposition shows that wage markup shocks are the main driver of economic fluctuations and that these shocks are better contained, even in relative terms, when credibility is high. We then show that the degree of credibility impacts the effect of wage flexibility on welfare. When credibility is low, monetary policy is less potent and the economy can experience a feedback loop between wage volatility and price volatility. We show, though, that once wage markup shocks are taken into account, wage flexibility is usually welfare improving.     

我国资产价格波动与货币政策关系研究

随着金融自由化的逐步推进,资本市场存量日益增大.这既体现了金融深化程度的提高,又意味着货币供应与国民经济主要指标之间稳定性的弱化.资产价格对货币政策的制订和执行会产生深刻的影响.其中股价、房价等资产价格在货币政策传导机制中扮演的角色越来越重要.本文从实证角度出发,通过构建VAR模型检验我国资产价格对货币政策的反应以及资产价格对货币政策目标的影响,发现资产价格、货币政策及货币政策目标间存在长期协整关系,资产价格对产出有正向冲击作用,股市显著影响通货膨胀,但房地产市场对通货膨胀推动作用不明显,资产价格受货币政策的冲击影响显著,其中股市对货币政策冲击的反应明显大于房地产市场.     

Macroeconomic policy and aggregate fluctuations in a semi-industrialized open economy: Greece 1951–1980

In this paper we model the effects of macroeconomic policy in a semi-industrialized open economy. Greece is our case, but the model could apply to other similar economies with tightly controlled financial markets and comprehensive foreign exchange restrictions, where both the exchange rate and interest rates are administered prices. The model consists of three equations which determine output, the price level and the trade balance. It is largely non-Keynesian, but, through the real exchange rate, it allows for anticipated monetary policy to affect real output. The model is estimated by FIML and its various restrictions cannot be rejected. A policy simulation suggests that even Friedman's x% money growth rule would ensure greater macroeconomic stability in the 1970s than the monetary policy that was actually followed.     

ENDOGENOUS TIME PREFERENCE,INTEREST‐RATE RULES,AND INDETERMINACY*

This paper extends the Benhabib et al. flexible‐price, money‐in‐the‐utility‐function model by considering endogenous time preference and re‐examines equilibrium indeterminacy in response to alternative interest‐rate rules. We show that either an active or a passive interest‐rate feedback rule can generate local indeterminacy even if consumption and real money balances are Edgeworth independent. This result is in sharp contrast to that in the related literature. We also find that in the presence of endogenous time preference, local indeterminacy may occur regardless of whether the monetary policy is based on the interest‐rate feedback rule or money growth‐rate targeting.     

The impact of monetary policy on local housing markets: Do regulations matter?

This paper shows that monetary policy has uneven impacts on local housing markets, and that the magnitude of the impacts are correlated with housing supply regulations. We apply the linearized present value model, which allows the log rent–price ratio to be decomposed into the expected present values of all future real interests rates, real housing premia, and real rent growth, to the housing markets in 23 US metropolitan statistical areas. Based on the indirect inference bias-corrected VAR estimates, we find that MSAs that are more regulated have (i) a higher variance in the log rent–price ratio, (ii) a larger share of the variance explained by real interest rate, and (iii) a stronger impulse response of house price to the real interest rate shock.     

Financial market imperfections and monetary policy strategy

In a model with imperfect money, credit and reserve markets, we examine if an inflation-targeting central bank applying the funds rate operating procedure to indirectly control market interest rates also needs a monetary aggregate as policy instrument. We show that if private agents use information extracted from money and financial markets to form inflation expectations and if interest rate pass-through is incomplete, the central bank can use a narrow monetary aggregate and the discount interest rate as independent and complementary policy instruments to reinforce the credibility of its announcements and the role of inflation target as a nominal anchor for inflation expectations. This study shows how a monetary policy strategy combining inflation targeting and monetary targeting can be conceived to guarantee macroeconomic stability and the credibility of monetary policy. Friedman's k-percent money growth rule, which can generate dynamic instability, and two alternative stabilizing feedback monetary targeting rules are examined.     

Inflation Targeting versus Nominal Income Targeting

In this paper we analyze two different target regimes, flexible inflation targeting and nominal income targeting, under discretion in a simple dynamic macro model. The key results of our paper are: First, for both targeting regimes optimal monetary policy response leads to a shock-dependent feedback rule. Second, a demand shock is completely offset by both monetary strategies. Third, in case of a supply shock there is a significant difference between the two different targeting regimes. Under inflation targeting the policy makers face a trade-off between inflation and output stabilization. This trade-off depends on the weight Φ the policy makers attach to output stabilization relative to inflation stabilization in the loss function. In contrast, under nominal income targeting policy makers face a constant trade-off between inflation and real output growth: an increase in inflation leads to a fall in real output growth by an equal amount. Furthermore, in Appendix A we analyze a (linear) commitment solution for inflation targeting and compare it with the discretionary case. Under commitment, inflation is smaller and the output gap is larger than under discretion. In Appendix B, we investigate inflation targeting in a two-period time-lag version of the model. The qualitative results on the trade-off between inflation and output growth remain the same as in the basic model without time lag.

Fiscal expansion, monetary policy, interest rate risk premia, and wage reactions

We examine the macroeconomic implications of fiscal policy in a small open economy, with emphasis on the interactions between fiscal, monetary and labour market policies. The paper uses the NBNZ-DEMONZ macroeconometric model. Novel features of the model are that it includes an endogenous interest rate risk premium (IRRP), and forward-looking monetary and fiscal policy reaction functions which capture the essence of New Zealand's Reserve Bank and Fiscal Responsibility Acts. The most important empirical result is that the postulated IRRP, proxying financial market mechanisms, can contribute at least as much as the monetary policy reaction function to maintaining price stability. Also of significance are that an income tax cuts package shows more damped real GDP and underlying inflation paths than does an expenditure increases equivalent; and that the inflationary and real sector impacts of a personal income tax cut package depend heavily on how the cut is `shared' between firms and workers. The nature and interdependence of monetary and fiscal policies and labour market conditions are therefore crucial to the macroeconomic outcomes.     

Optimal Monetary Policy

Optimal monetary policy maximizes the welfare of a representative agent, given frictions in the economic environment. Constructing a model with two sets of frictions—costly price adjustment by imperfectly competitive firms and costly exchange of wealth for goods—we find optimal monetary policy is governed by two familiar principles. First, the average level of the nominal interest rate should be sufficiently low, as suggested by Milton Friedman, that there should be deflation on average. Yet, the Keynesian frictions imply that the optimal nominal interest rate is positive. Second, as various shocks occur to the real and monetary sectors, the price level should be largely stabilized, as suggested by Irving Fisher, albeit around a deflationary trend path. Since expected inflation is roughly constant through time, the nominal interest rate must therefore vary with the Fisherian determinants of the real interest rate. Although the monetary authority has substantial leverage over real activity in our model economy, it chooses real allocations that closely resemble those which would occur if prices were flexible. In our benchmark model, there is some tendency for the monetary authority to smooth nominal and real interest rates.     

Optimal monetary policy for a small open economy

This paper focuses on the design of monetary policy rules for a small open economy. The model features optimizing behavior, general equilibrium and price stickiness. The real exchange rate is shown to affect the firm's real marginal cost, aggregate supply and aggregate demand. The welfare objective depends on the openness of the economy, and the optimal policy rule differs from that which obtains in a closed economy. The inflation versus output gap stabilization trade-off is caused by the real exchange rate. The implied optimal monetary policy regime is domestic inflation target coupled with controlled floating of the real exchange rate.
