Money non-neutrality in a Rational Belief Equilibrium with financial assets

Summary. In Rational Beliefs Equilibria money is generically non-neutral. Given the expectational perspective proposed by the Theory of Rational Belief Equilibrium, we show that one of the most important factors in the emergence of money non-neutrality is played by Endogenous Uncertainty. This, in contrast to the Rational Expectations results of money neutrality and policy ineffectiveness, leads to a scenario in which monetary policy has an impact on the real economy and price volatility. The heterogeneity of beliefs together with the distribution and intensity of agents' states of optimism/pessimism can amplify the real effect of monetary policy and/or generate endogenous fluctuations in the economy which are not explained by any exogenous shock. We claim that money non-neutrality is mostly an expectations driven phenomenon. Indeed, additional assumptions of asymmetry of information and/or unanticipated monetary policy are not needed to explain the real effect of monetary policy as it is customary in the New Classical Theory.

Disinflation costs in China and monetary policy regimes

This paper investigates the real effects of a disinflationary policy in China, in which we conduct a disinflation experiment in a medium-scale New Keynesian model. We highlight two key features of China's economy: the relevance of money to monetary policy rules and household inequality. For the former, we consider two monetary policy regimes: an expanded Taylor rule with money and a money supply rule. For the latter, we take into account a share of the population that is limited in its ability to participate in assets markets. Our analysis suggests that a disinflation policy is more costly when the central bank controls the money supply than the case in which the nominal interest rate is the policy instrument. Our results are driven by the different impacts of disinflation on nominal and real interest rates under the two regimes.     

Is There a Bank-Lending Channel of Monetary Policy in New Zealand?

The results reported in the paper cast serious doubt on the existence of a potent bank-lending channel of monetary policy in New Zealand either before or after the reforms of the mid-1980s. We find no sound evidence of a link between a number of different finance mix variables and economic activity in New Zealand. Similar, unfavourable results are reported by the investigation of the connection between movements in an interest rate spread and real economic performance. Moreover, neither the finance mix variables nor the spread respond consistently to changes in various indicators of monetary policy.     

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.     

Uncertainty shocks,precautionary pricing,and optimal monetary policy

Existing studies show that, in standard New Keynesian models, uncertainty shocks manifest as cost-push shocks due to the precautionary pricing channel. We study optimal monetary policy in response to uncertainty shocks when the precautionary pricing channel is operative. We show that, in the absence of real imperfections, the optimal monetary policy fully stabilizes the output gap and inflation, implying no policy trade-offs. Our result suggests that precautionary pricing matters only insofar as expected inflation is volatile. Thus, a simple Taylor rule that places high weight on inflation leads to a stabilized output gap, thereby attaining the “divine coincidence”.     

INTERNATIONAL CREDIT CHANNEL OF MONETARY POLICY: AN EMPIRICAL NOTE

A longstanding macroeconomic issue is how monetary policy affects the real economy. There are economists placing an emphasis on the role of bank lending in monetary transmission. Their view, called the credit view, is that a monetary tightening shifts the supply schedule of bank loans left, thereby forcing bank‐dependent borrowers to cut back on expenditures. In the literature, the credit view is typically studied in a closed‐economy context. In reality, however, banks make international loans through their overseas branches and subsidiaries. This suggests that the credit view should be studied in an open‐economy context. This paper proposes the international credit view: a monetary‐policy shock originated in one country propagates to another through banks’ reallocation of funds between the two countries. For testing the hypothesis, Australia and New Zealand provide an excellent case to study. This is because Australian‐owned banks dominate the banking market in New Zealand. This paper aims to test the international credit view within a framework of vector auto‐regression models. A significant and robust finding is that the supply schedule of loans shifts left in New Zealand after a monetary tightening in Australia.     

Helicopter Ben,Monetarism, The New Keynesian Credit View and Loanable Funds

Abstract:

The purpose of this article is to examine the intellectual roots of monetary dominance over fiscal policy. A first step was Milton Friedman’s reinterpretation of the Great Depression based on the money-multiplier story associated with the fractional-reserve system. In the 1990s New Keynesian authors and Ben Bernanke in particular never got away from Friedman’s interpretation and remained faithful to the loanable funds theory despite their new focus on bank credit and their apparent abandonment of monetarism. New Consensus Macroeconomics kept arguing that expansionary fiscal policy could only lead to higher inflation rates and real interest rates that lowered potential output. The New Keynesian literature on the zero lower bound of the early 2000s thus mostly overlooked the benefits of expansionary fiscal policy; instead, the optimism on unconventional monetary policies failed to prepare policymakers for the Global Financial Crisis. The crisis demands far-reaching changes to monetary and macro theory not least of which is a recognition that the theory of loanable funds is incapable of providing any insight into how the financial system works in practice.     

“CONVENTIONAL” MONETARY POLICY IN OLG MODELS: REVISITING THE ASSET-SUBSTITUTION CHANNEL

Conventional monetary policy involves actions by the monetary and fiscal authorities: the former sets a nominal interest rate and the latter sets lump-sum taxes to finance the implied flow of interest payments on government debt. We model such policy within an overlapping generations framework and show that absent any other frictions the magnitude of the nominal interest rate gives rise to asset substitution between government debt and either private debt or capital—substitution that has both real and nominal effects. Such substitution is not in standard New Keynesian models because their dynastic specification implies that government debt is not net wealth.     

Why does monetary policy respond to the real exchange rate in small open economies? A Bayesian perspective

To estimate how monetary policy works in small open economies, we build a dynamic stochastic general equilibrium model that incorporates the basic features of these economies. We conclude that the monetary policy in a group of small open economies (including Australia, Chile, Colombia, Peru, and New Zealand) is rather similar to that observed in closed economies. Our results also indicate, however, that there are strong differences due to the shocks from the international financial markets (mainly risk premium shocks). These differences explain most of the variability of the real exchange rate, which has important reallocation effects in the short run. Our results are consistent with an old idea from the Mundell–Fleming model: namely, a real depreciation to confront a risk premium shock is expansive or procyclical, in contradiction to the predictions of the balance sheet effect, the J curve effect, and the introduction of working capital into RBC models. In line with this last result, we have strong evidence that only in one of the five countries analyzed in this study does not intervene the real exchange rate, the case of New Zealand.

The effects of the monetary policy regime shift to inflation targeting on the real interest rate in the United Kingdom

This paper studies the effects of the monetary policy regime shift to inflation targeting on the stochastic properties of the real interest rate in the U.K. The empirical analysis suggests a constant mean of the real interest rate that shifts with the monetary policy regime change to inflation targeting in October 1992. The mean-reverting level of the real interest rate has decreased from 5.1% to 2.3% per annum with the change in monetary policy to inflation targeting. In addition, the shift in monetary policy regime to inflation targeting has reduced the volatility of the real interest rate and increased the persistence of real interest rate deviations from the mean. The results suggest that the central bank can affect the stochastic properties of the real interest rate through the choice of monetary policy regime over a long period of time.     

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.     

货币冲击与中国经济波动——基于DSGE模型的数量分析

基于1993~2008年的季度数据,本文在一个包含Calvo价格粘性的新凯恩斯主义模型中,讨论了中国货币冲击与经济增长的关系。在假定货币政策通过调整货币供给增长实施的前提下,本文根据模型模拟和实际数据的对比以及脉冲响应函数分析得出以下结论:(1)货币并非我国经济波动根源,实际产出对货币供给具有一定反馈作用。(2)通货膨胀的顺周期性和领先增长表明中国经济周期存在总需求拉动的特性。物价波动在中短期主要由货币供应量波动引起。(3)货币政策对实体经济有效但效果有限,货币供给变动对投资的作用效力更大,对消费需求刺激有限。     

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.     

货币政策对房地产市场冲击效力的动态测度

以货币政策传导渠道为理论依据,通过结构向量自回归(SVAR)模型构造货币政策对房地产市场的作用途径,可测度各种货币政策工具冲击对我国房地产市场供求的相对强度.实证分析结果表明,利率政策的冲击效力明显且持久,是调控房地产市场最有效的货币政策工具;紧缩的信贷政策仅能在短期内抑制房地产市场需求,长期效果欠佳;而货币供给量冲击对房地产市场的影响并不显著.相对于房地产需求,房地产市场供给对各种货币政策工具冲击的响应深度高,但响应速度较慢.     

Does monetary policy affect the long-run expectations of non-stationary real interest rates?

In this article, we analyse whether the monetary policy affects the long-run expectation of the non-stationary real interest rate. The analysis is conducted through Beveridge–Nelson trend decomposition within a cointegrated vector autoregressive model based on the New Keynesian framework. We suggest an augmented test of the conventional co-integration test on the non-stationarity of the real interest rate, which checks whether the co-integration coefficient of inflation is one and the output gap affects the co-integration equilibrium of the nominal interest rate. We further suggest decomposing the long-run expectation of the non-stationary real interest rate into three trends: the interest rate shock (including the monetary shock), inflation shock and output gap shock. According to empirical analyses using monthly US data after the Korean War, the long-run expectation of the non-stationary real interest rate contains an interest rate shock trend and the impulse of the federal fund target rate induces a significant response of the interest rate shock trend. However, the interest rate shock trend has a very small portion of the long-run expectation of the non-stationary real interest rate, which may explain why the monetary policy was not particularly effective in the economic recovery after the global financial crisis.     

A two-pillar DSGE monetary policy model for the euro area

The current financial crisis has revived the interest for monitoring both monetary and credit developments. Over the past two decades, consistent with the adoption of inflation targeting strategies by a growing number of central banks and the development of New Keynesian models for which monetary aggregates are largely irrelevant, money and credit have been progressively neglected in the conduct of monetary policy. A striking exception has been the Eurosystem, which has implemented a strategy known as the “two-pillar monetary policy strategy” giving a prominent role for money. In this paper, we develop a small optimizing model based on Ireland (2004), estimated on euro area data and featuring this two-pillar strategy. We evaluate an ECB-style cross-checking policy rule in a DSGE model with real balance effects of money. We find some evidence that indeed money plays a non-trivial role in explaining the euro area business cycle. This provides a rationale for the central bank to factor in monetary developments but also raises some issues regarding the reliability of M3 as an appropriate monetary indicator. We find some evidence that the ECB has systematically reacted to a filtered measure of money growth but weak evidence it has reacted more aggressively during excess money growth periods.     

基于SVAR的中国货币政策的房价传导机制

本文采用2005年7月到2009年9月宏观经济数据构建SVAR模型,分别从货币供给的利率传导机制,现金余额效应,汇率传导机制以及房地产价格对货币供给的反馈机制四个角度进行实证分析,发现:货币量的增加和汇率上升都会带来房价的大幅上涨,而利率提高所带来的房价下降程度很小,房价的上涨会引起物价和消费上涨。结论:当今房地产市场中,存在着货币政策的房价传导机制,其中利率机制对房价影响较小;在汇率机制传导过程中,中央银行为了稳定币值和升值预期引起的国际资本流入导致货币供应量被动增加,从而直接导致了房地产价格上涨。因此提出货币政策应当关注房地产价格,既要防止形成房地产价格泡沫,又要避免温水煮青蛙。     

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.
