Effectiveness of monetary policy and limited asset market participation: Neoclassical versus Keynesian effects

This paper investigates the effects of limited asset market participation on the effectiveness of monetary policy in a New Keynesian Dynamic Stochastic General Equilibrium model. Although an increase in consumers who cannot access financial markets reduces the effects of interest rate policies through consumption inter-temporal allocation (neoclassical or permanent income effect), we find an opposite result: monetary policy becomes more effective as the degree of financial market participation falls. The reason has a very Keynesian flavor.     

Influence of the Banks' Money Mediation Behavior on the Monetary Policy: A Study of Korean Case

Abstract

This paper analyses how financial institutions' arbitrary intermediation behaviors, including adjustments in bank lending and deposit rates, influence monetary policy transmission channels. For the analysis, we develop a New Keynesian Dynamic Stochastic General Equilibrium (NK DSGE) model with parameters estimated to fit the Korean conditions. The role of banks is subsequently examined by classifying monetary policy transmission channels (real rate channel, nominal debt channel, financial accelerating channel, and banking attenuator channel). A notable part of this analysis is the inclusion of the banking sector in the model specifically with the intent to study transmissions from the financial sector to the real economy. This paper follows this line of inquiry with recent research in mind. Empirical analysis verifies the existence of the banking attenuator effect in Korea, which means banks act to reduce the effect of monetary policies. This indicates that if financial intermediaries strengthen arbitrary adjustment behaviors of lending and deposit rates, the effect of the monetary policy intended to relieve volatility in the business cycle may not be as high as expected.     

The Optimal Monetary and Macroprudential Policies for the South African Economy

We investigate the optimal design and effectiveness of monetary and macroprudential policies in promoting macroeconomic (price) and financial stability for the South African economy. We develop a New Keynesian dynamic stochastic general equilibrium model featuring a housing market, a banking sector and the role of macroprudential and monetary policies. Based on the parameter estimates from the estimation, we conduct an optimal rule analysis and an efficient policy frontier analysis, and compare the dynamics of the model under different policy regimes. We find that a policy regime that combines a standard monetary policy rule and a macroprudential policy rule delivers a more stable economic system with price and financial stability. A policy regime that combines an augmented monetary policy (policy rate reacts to financial conditions) with macroprudential policy is better at attenuating the effects of financial shocks, but at a much higher cost of price instability. Our findings suggest that monetary policy should focus solely on its primary objective of price stability and let macroprudential policy facilitate financial stability on its own.     

Monetary analysis and the global financial cycle: An Asian central bank perspective

Emerging Asia has seen a transformation of its monetary policy environment over the past two decades. By far, the most relevant change has been the maturing of its financial systems and the growing relevance of the global financial cycle: financial inclusion has spread, financial markets have deepened and financial globalisation has linked domestic markets closer to international markets. One consequence of the maturing of the financial systems has been the weakening of the traditional case for the monetarist view of the roles of monetary aggregates in the conduct of monetary policy. In addition, the maturing of the financial systems has elevated concerns of financial stability, as both a source of shocks and a responsibility of central banks. These developments have been further complicated by monetary policy spillovers from the advanced economies. All this points to the need to consider alternatives to conventional inflation targeting frameworks. This paper lays out a policy framework based on a multi-pillar monetary policy approach as a potentially attractive alternative for EM Asia. The three pillars are based on economic, financial and exchange rate stability, respectively. This framework not only offers an alternative conceptual framework but also implies institutional reforms to ensure central banks take a longer term perspective when setting policy.     

Myopia,Discretion, and Commitment in a Two‐Period AS/AD Model

A large body of pedagogical literature has recently emerged to place the New Keynesian framework for analyzing business cycle fluctuations and the conduct of monetary policy into undergraduate economics curricula. This article develops the graphical apparatus for the analysis of optimal monetary policy in the context of a two‐period model under alternative assumptions about the formation of inflationary expectations. It demonstrates that differences in assumptions about the formation of inflationary expectations translate into quite different conclusions regarding the optimal conduct of monetary policy.     

Will the Sarb always Succeed in Fighting Inflation with Contractionary Policy?

The conventional view is that a monetary policy shock has both supply‐side and demand‐side effects, at least in the short run. Barth and Ramey show that the supply‐side effect of a monetary policy shock may be greater than the demand‐side effect. We argue that it is crucial for monetary authorities to understand whether an increase in expected future inflation is due to supply shocks or demand shocks before applying contractionary policy to forestall inflation. We estimate a standard New Keynesian dynamic stochastic general equilibrium model with the cost channel of monetary policy for the South African economy to show that whether the South African Reserve Bank should apply contractionary policy to fight inflation depends critically on the nature of the disturbance. If an increase in expected future inflation is mainly due to supply shocks, the South African Reserve Bank should not apply contractionary policy to fight inflation, as this would lead to a persistent increase in inflation and a greater loss in output. Our estimation results also show that with a moderate level of cost‐channel effect and nominal rigidities, a New Keynesian dynamic stochastic general equilibrium model with the cost channel of monetary policy is able to mimic the price puzzle produced by an estimated vector autoregressive model.     

Real business cycle models and money: A survey of theories and stylized facts

Real Business Cycle Models and Money: A Survey of Theories and Stylized Facts. — This article presents a survey of real business cycle theory, with special attention to the role of money. This role is mainly associated with cash-in-advance constraints, liquidity effects and aspects of financial intermediation. Apart from reviewing the literature, stylized facts about the comovements of output and prices versus monetary aggregates and interest rates over the cycle are assembled and discussed for eight industrial countries, including the G5-countries, Denmark, Belgium and the Netherlands. The paper concludes that further developments in monetary real business cycle theory could benefit from taking into account a broader set of stylized facts about prices than has been done thus far, as well as from introducing non-Walrasian elements and endogenizing monetary policy.     

Effects of Monetary Policy during Financial Market Crises and Regime Changes: An Empirical Evaluation Using a Nonlinear Vector Autoregression Model

Using monthly data for Korea, this study examines nonlinear effects of monetary policy in association with financial market distress. The study uses a nonlinear vector autoregression model and finds that monetary policy becomes ineffective for addressing huge demand contractions in times of financial market turmoil or severe economic downturn, implying a structural change from a non‐Keynesian to a Keynesian regime, such as a liquidity trap. Monetary contractions have stronger output effects than monetary expansions, particularly in times of financial distress. We found no evidence in favor of asymmetric effects of monetary shocks of different sizes. Finally, we also found financial shocks to have stronger effects on the real economy in times of financial distress than in normal times. The results have important policy implications for periods of financial turmoil or economic crisis.

New Keynesian Explanations of Cyclical Movements in Aggregate Inflation and Regional Inflation Differentials

What determines the cyclical behavior of aggregate inflation and regional inflation differentials? The answer has strong implications for monetary policy and in Europe for the Stability and Growth Pact. In the United States, inflation rates move pro-cyclically, and across the Euro Area, inflation differentials are positively correlated with growth differentials. This suggests that demand shocks are the primary determinants of the cyclical behavior of aggregate inflation and regional inflation differentials. In this paper, we discuss New Keynesian explanations of these correlations, and we argue that demand shocks are either missing or inadequately modeled in the in typical New Keynesian model.     

Financial Deregulation and the Bank Lending Channel in Developing Countries: The Case of Indonesia

The dominant role of commercial banks as a source of finance and the considerable asymmetry of information in financial markets in developing countries have raised an argument that the bank lending channel of monetary transmission mechanism would be very important in such countries. This study addresses the issue by investigating empirically whether there are differential effects of monetary policy on banks' balance sheets, and its implications to the existence of the bank lending channel of monetary policy in Indonesia, especially since the early 1980s when the government adopted a policy of financial deveculation. We find significant differences of balance sheet behaviour across bank classes in response to a change in monetary policy, consistent with the predictions of the bank lending view. We also found that because of access to foreign funds and the existence of bank loan commitment, the monetary policy was unable to constrain loan supply by the large (state) banks, indicating that the bank lending channel operates through smaller (non-state) banks.     

A New Keynesian model for analysing monetary policy in Mainland China

This paper adopts a four-equation New Keynesian model to evaluate the appropriateness of China's monetary policy framework. Our simulation results show that a hybrid rule that uses both interest rate and quantity of money as instruments outperforms the rules using one instrument alone at the current stage of economic and financial market development. Our analysis also shows that a sharp appreciation of the renminbi exchange rate, though effective in containing inflation pressures, would be quite disruptive to growth.     

Central Bank Policy in a More Perfect Financial System

Financial innovation increases markets' liquidity and provides economic agents with new instruments to better handle risks, but it reduces the efficacy of monetary policy while strengthening the logic and force of the “unholy trinity”. Increased liquidity of financial markets and increased leverage of financial positions imply that speculators can attack unsustainable fixed exchange rates faster and more powerfully than ever. The rapid innovation of new financial instruments in these markets also implies the futility to “throw sand in the wheels” through regulation or the introduction of transaction taxes. The higher asset substitutability generated by the emergence of derivatives makes the definition of “money,” particularly of broad monetary aggregates, increasingly difficult. In a more complete financial market system central banks find it harder to predict the effect of a given monetary impulse on real output and employment with any reasonable precision. Discretionary monetary policies aimed at output and employment become more uncertain. Consequently, central banks should focus on the long-run goal of price stability.     

Spillovers of the Conventional and Unconventional Monetary Policy from the US to South Africa

This paper assesses the effect of US monetary policy on South Africa during the period 1990–2018. We separately analyse and compare the effect of conventional monetary policy, before the Global Financial Crisis, and unconventional monetary policy, after the US monetary policy reached the zero-lower bound. Our impulse response function results indicate that monetary policy in South Africa responds mainly to local inflation, economic activity and financial conditions. While there is strong correlation between the global and South African financial cycle, the financial cycle is not transmitted to the real economy because of the sluggish response of industrial production and domestic credit, especially after the global financial crisis. We see this as an indication of the effects of structural issues to the real economy and constrained households’ balance sheet which has prevented the local economy to take advantage of low local interest rates and the global economic recovery after the crisis.     

The appropriate intermediate target for monetary policy in less developed countries: Empirical evidence

It is argued in this paper that recent financial innovations and deregulation in less developed countries may have established a case for an intermediate target strategy for monetary policy. The question of which financial aggregate to target is not, however, a trivial one. Three criteria have to be met for a financial aggregate to serve as an appropriate target for monetary policy. Using time series data from a sample of six less developed countries, these three criteria are empirically tested to determine whether narrow money, broad money or domestic credit is the most appropriate target for monetary policy in less developed countries. The results indicate that it is difficult to generalize and that until monetary policy can be independent of fiscal policy in these countries, none of the tested financial aggregates would be appropriate as an intermediate target.     

基于金融稳定目标的规则型货币政策研究

随着货币政策与金融稳定之间联系的不断深化，中央银行理应在防范金融市场系统性风险中发挥重要的作用。文章首先构建我国金融稳定指数，并将其加入线性货币政策规则，研究结果表明，中央银行在调整名义利率时的确对金融稳定状况有所关注，相比于传统泰勒规则，纳入金融稳定指数的泰勒规则中通胀系数与产出缺口系数均有显著改善，其能够更好地拟合中央银行的实际政策操作。随后，为了进一步考察货币当局对名义利率调整的动态变化特征，文章通过TVP-SV-VAR模型对拓展的时变参数泰勒规则进行了再估计。研究发现，随着经济周期和金融形势的更迭，中央银行也会不断动态调整其政策目标。其中，货币政策对通货膨胀的调控不存在明显的惰性区域，控制通胀始终是中央银行工作的重心。其次，中央银行存在规避经济收缩的偏好，在经济下行时期其对货币政策的调整会向产出缺口倾斜。最后，为了抑制金融机构的过度风险承担，货币当局在本次金融危机之后显著增强了对于金融稳定的关注。     

Monetary policy rules for a developing country: Evidence from Pakistan

This paper estimates forward-looking monetary policy rules to examine the interest rate setting behavior of the State Bank of Pakistan. Considering the external constraints on monetary policy, core inflation and a country-specific measure of the output gap, we demonstrate that the State Bank of Pakistan reacts to changes in inflation, the output gap and the federal funds rate.     

US vs. euro area: Who drives cross-border bank lending to EMs?

This paper analyzes the drivers of cross-border bank lending to 49 Emerging Markets (EMs) during the period 1990Q1–2014Q4, by assessing the impact of monetary, financial and real sector shocks in both the US and the euro area. The literature has traditionally highlighted the influence of US monetary policy on driving cross-border bank flows, and more recently the importance of both US and Euro Area (EA) financial/banking sectors’ related variables. Our contribution is the simultaneous analysis of the role of these US and EA drivers, as well as their interactions with real sector shocks. We corroborate the negative impact of US monetary policy tightening on cross-border lending to EMs, but we find that EA monetary policy seems to have an impact mostly on Emerging Europe, reflecting the fact that cross-border lending to most other EM regions is dollar denominated. We also find that real sector shocks in both the US and EA trigger an increase in cross-border lending, but less in EA when modeling the financial sector. Finally, for financial sector shocks, such as those associated with a decrease in bank leverage, our results indicate a broad-based overall contraction of cross-border lending if the shock originates in the US, and heterogenous effects across borrowing regions if the shock originates in the EA.     

An Empirical Analysis of the Austrian Business Cycle Theory

The Austrian economists Ludwig von Mises and Friedrich A. Hayek developed a unique theory of the business cycle. In their view, an unsustainable boom ensues when the rate of interest prevailing in the market falls below the natural rate. The boom is characterized not only by an increase in aggregate production but also by a distortion of the structure of production. Similarly, the recession that follows is characterized by a decline in aggregate production as the structure of production is repaired. Hence, the Austrian account of macroeconomic fluctuation stresses the misallocation and reallocation of resources in addition to the overproduction and underproduction of more conventional business cycle theories. In a recent article, Lester and Wolff (Review of Austrian Economics 26(4):433–461, 2013) attempt to consider the empirical relevance of the Austrian view. We argue that the authors’ use of the federal funds rate as an indicator of monetary policy is inappropriate in that it fails to distinguish a low market interest rate from a market interest rate that is low relative to the natural rate. Using an estimate of the natural rate provided by Selgin et al. (2011), we attempt to improve upon their analysis.
