Does the Reserve Bank of Australia follow a forward-looking nonlinear monetary policy rule?

ABSTRACT

The conventional monetary policy rule describes a simple linear relationship between the domestic interest rate, inflation rate and output gap. An important extension to this rule is to incorporate the forward-looking behaviour of central banks, where it is assumed that they target an expected level of inflation instead of its current realised value. Using quarterly observations for the period 1993:1-2018:2, this paper investigates whether the conduct of monetary policy in Australia can be described by a forward-looking linear monetary policy rule, or by a nonlinear forward-looking monetary policy rule. In particular, the nonlinear forward-looking monetary policy rule is analysed in a regime-switching framework using a smooth logistic transition regression model. While the results show that the conventional forward-looking linear monetary policy rule describes the application of monetary policy in Australia reasonably well, the interest rate setting behaviour of the RBA is best described by a nonlinear forward-looking monetary policy rule.

Tobin's Q channel and monetary policy rules under incomplete exchange rate pass-through

This paper focuses on the role of the Tobin's Q channel in a two-country framework in which exporting firms set their prices on the basis of local currency pricing. Incomplete exchange rate pass-through significantly affects the Tobin's Q channel in each country compared with the case of complete exchange rate pass-through. We explore whether different specifications of monetary policy enhance social welfare. Regardless of the degree of home bias, a monetary policy rule that stabilizes domestic asset prices attains preferable outcomes to several alternative policy rules considered in our analysis. Notably, there are large gains from employing a domestic asset price rule when the home bias is large. A monetary policy rule that stabilizes the asset prices of both countries results in worse outcomes. Our simulation results suggest that stabilizing asset prices is important in an open economy with incomplete exchange rate pass-through.     

The effects of fiscal spending shocks on the performance of simple monetary policy rules

We examine the effects of fiscal shocks on the performance of alternative monetary policy rules in a small dynamic general equilibrium framework. We explicitly consider the interaction between fiscal and monetary policy rules which may be present in the real world. We use a simple specification for the fiscal policy rule and various specifications for the (simple) monetary policy rule. Our analysis suggests that some form of flexible inflation targeting regime would perform well in response to fiscal shocks compared to other forms of policy regimes.

Optimal monetary and fiscal policies in a search theoretic model of monetary exchange

Search models of monetary exchange commonly assume that terms of trade in anonymous markets are determined via Nash bargaining, which generally causes monetary equilibrium to be inefficient. Bargaining frictions add to the classical intertemporal distortion present in most monetary models, whereby agents work today to obtain cash that can be used only in future transactions. In this paper, we study the properties of optimal fiscal and monetary policy within the framework of Lagos and Wright (2005). We show that fiscal policy can be implemented to alleviate underproduction while money is still essential. If lump sum monetary transfers are available, a production subsidy can restore the efficiency of monetary equilibria. The Friedman rule belongs to the optimal policy set, but higher inflation rates are also possible. When lump-sum monetary transfers are not available, equilibrium allocations are generally not first-best. Nevertheless, fiscal policy still results in substantial welfare gains. Money can be extracted from circulation via a sales tax on decentralized market activities, and the Friedman rule is only optimal if the buyer has relatively low bargaining power.     

An equilibrium voting model of federal standards with externalities

This paper proposes a framework for studying policy making in a federal system in the presence of spillover externalities. Local jurisdictions choose local policies by majority rule subject to standards that are set by majority rule at the federal level. We characterize the induced preferences of voters for federal policies, prove existence of local majority rule equilibrium, provide an example of non-existence of global majority rule equilibrium, and explore the welfare properties of federal standards in the presence of spillovers.     

Limited asset markets participation, monetary policy and (inverted) aggregate demand logic

This paper incorporates limited asset markets participation in dynamic general equilibrium and develops a simple analytical framework for monetary policy analysis. Aggregate dynamics and stability properties of an otherwise standard business cycle model depend nonlinearly on the degree of asset market participation. While ‘moderate’ participation rates strengthen the role of monetary policy, low enough participation causes an inversion of results dictated by conventional wisdom. The slope of the ‘IS’ curve changes sign, the ‘Taylor principle’ is inverted, optimal welfare-maximizing discretionary monetary policy requires a passive policy rule and the effects and propagation of shocks are changed. However, a targeting rule implementing optimal policy under commitment delivers equilibrium determinacy regardless of the degree of asset market participation. Our results may justify Fed's behavior during the ‘Great Inflation’ period.     

Why Economists should Choose their Inheritance: Physics and Path-independence in Economic Systems

Abstract

This paper considers the possibility of using fiscal rather than monetary policy as the instrument of stabilization policy in a new consensus framework. Describing the conduct of fiscal policy in terms of a ‘pseudo Taylor rule’, it is shown that fiscal policy is as, if not more, effective than monetary policy as a tool for macroeconomic stabilization. The conclusion reached is that the comparative neglect of fiscal policy as an instrument of stabilization policy in new consensus macroeconomics is unwarranted.     

Deflationary policy under digital and fiat currency competition

I examine the implications of digital and fiat currency competition on optimal monetary policy according to the Friedman rule (a standard deflationary policy) in a Fernández-Villaverde and Sanches (2016) framework, with no search friction. Consistent with the existing literature, first, I find that monetary equilibrium under a purely private arrangement of digital currencies will not deliver a socially efficient allocation. Second, I place restrictions on the available supply of digital currencies and find that a socially efficient allocation is possible only if the upper bound on digital currency circulation is equal to the rate of time-preference, albeit some degree of government intervention is required to curb the profit-maximizing incentive of the miners. Third, I find that optimal monetary policy at the Friedman rule will be socially inefficient when digital currencies compete with government-issued fiat money. Finally, I show that the Friedman rule is a socially desirable policy only in a purely fiat monetary regime.     

A comparison of optimal policy rules prior to and during inflation targeting: empirical evidence from Bank of Canada

We examine policy rules that are consistent with inflation targeting (IT) framework in a small macroeconomic model of the Canadian economy. We set up an optimal linear regulator problem and derive policy rules to compare the dynamics of pre-IT and IT eras. We find that while the optimal monetary policy rule in the pre-IT period is best described with a loss function that attaches equal weight to price stability, financial stability and output stability; the IT era is dominated by the price stability objective followed by the financial stability and output stability, consecutively. Moreover, we do not find an explicit role for exchange rate stability in the objective function of the Bank of Canada for both monetary policy eras. We, then, compare the properties of the derived optimal rules with those of an ad hoc Taylor rule for the IT period. In response to inflationary shocks, Taylor rule brings down inflation rates more quickly compared to the derived policy rules, but at the cost of a higher sacrifice ratio and more volatile interest rates.     

Credible enough? Forward guidance and perceived National Bank of Poland’s policy rule

Forward guidance effectiveness is conditional upon its credibility. This policy, when taken as credible, should reduce the perceived impact of macroeconomic variables on the interest rate. Using the Taylor rule framework and employing micro-level data set, we test the perception of monetary policy in Poland among professional forecasters. Our results show that the Taylor principle is violated in the forward guidance period, which provides evidence for forward guidance credibility.     

Monetary policy rules with PID control features: evidence from the UK,USA and EU

ABSTRACT

This paper considers the extent to which the monetary policy operations of three major central banks can be regarded as an application of Proportional-Integral-Derivative (PID) control rules. The paper outlines the general PID framework and estimates a series of dynamic models to identify how interest rate policy adjustments are affected by the rate of inflation and the level of macroeconomic activity. The paper examines data for the UK, the USA and the Eurozone. The results suggest that the PID rules can provide a useful theoretical and empirical framework for estimating central bank responses to the inflation and macroeconomic activity variables by improving the explanatory power of the Taylor rule model and determining the effect of the parameters.     

Budgetary policies in a DSGE model with finite horizons

This paper presents a dynamic stochastic general equilibrium model with nominal rigidities, capital accumulation and finite horizons. Our New Keynesian framework exhibits intergenerational wealth effects and is intended to investigate the macroeconomic implications of fiscal policy, which is specified by either a debt-based tax rule or a balanced-budget rule allowing for temporary deficits. The model predicts that fiscal expansions generate a trade-off in output dynamics between short-term gains and medium-term losses. It is shown that the effects of fiscal shocks crucially depend upon the conduct of monetary policy. Simulation analysis suggests that balanced-budget requirements enhance the determinacy properties of feedback interest rate rules by guaranteeing inflation stabilization.     

The dynamic effectiveness of monetary policy in China: evidence from a TVP-SV-FAVAR model

We use a broad set of China’s macroeconomic indicators and a dynamic factor model to estimate latent factors of economic output and inflation, which are used to measure the ultimate objectives of monetary policy. The above factors and policy variables are incorporated into a TVP-SV-FAVAR model to investigate the dynamic effectiveness of Chinese monetary policy. Our results confirm that the effects of Chinese monetary policy are time-varying. By comparing the quantity rule with the price rule, we find that the price rule is more effective in managing China’s macro-economy, especially after the financial crisis. Moreover, the results can be regarded as a division of policy rules in a way that different rules are directed at different objectives.

A macroeconometric framework for monetary policy evaluation: A case study of Pakistan

This paper attempts to establish the quantitative importance of the various channels of monetary transmission by constructing, estimating and simulating a small macroeconometric model of Pakistan's monetary sector, while using data from the monetary statistics and the monetary survey of the State Bank of Pakistan over 1976–2007. The paper elucidates that the key feature of the study of monetary policy in Pakistan has been preoccupied with neglect either of the demand or the supply function of money and shows how this may lead to imprecise policy actions and mistaken conclusions. Accordingly, we delineate the transmission mechanism of monetary policy by taking into consideration all structural money demand and money supply linkages along with the historically implied identifying assumption in the framework of a marginalized macroeconometric model. The within-sample and out-of-sample evaluations of the model are found satisfactory. The paper presents results of three policy simulations from the estimated model that highlight the impact of alternative monetary policy instruments on the monetary variables under a rule-based and a discretionary policy environment. We find that (i) the SBP subscribes to an unannounced monetary policy rule, (ii) the determination of the policy rate under the announced rule environment stabilizes the monetary sector in that convergence to full equilibrium is smooth and rapid, (iii) a 100 bps reduction in the discount rate, ceteris paribus, decreases money supply by 4.97%, and (iv) the long term implication of reducing (increasing) the reserve requirement ratio on time (demand) deposits, ceteris paribus, is only higher inflation. Finally, we establish that a 100 bps increase in interest rate increases money supply by 3.14% in full equilibrium.     

On the welfare implications of nominal GDP targeting

This paper examines the welfare implications of a nominal GDP growth targeting rule, a nominal GDP level targeting rule, and inflation targeting regime in a New Keynesian model featuring positive trend inflation, two measures of welfare, and both high and low growth environments. The paper finds that (i) in general, nominal GDP growth targeting dominates other rules with changes in all dimensions; (ii) nominal GDP growth targeting framework is superior to the level targeting regime for most scenarios; (iii) inflation targeting is preferred to nominal GDP level targeting regime, but to minimize short-run fluctuations, the latter is advantageous; (iv) nominal GDP level targeting may be desirable only in a low growth environment with both low inflation indexation and consumption equivalence criteria. The simulation results provide solid evidence to policy makers on the desirability of nominal GDP growth targeting.     

一般均衡中的利率、确定性与最优规则

利率规则理论是以短期利率作为货币政策工具而发展起来的一套新的理论,它体现了货币经济学家在货币政策领域内的新的尝试和努力。在利率规则理论中,货币经济学家试图解决两个问题:利率规则冲击对非政策经济变量的短期影响是什么,以及一个好的利率规则应当具有怎样的性质。利率规则将短期利率作为非政策经济变量的内生反应函数,使得货币经济学家可以在一般均衡模型中探讨这两个问题。然而,由于利率规则从一开始就是出于一种偏好的设定,因此,讨论的结果并不符合稳健性和科学性的要求,这就削弱了理论预言的可靠性。在某种意义上,利率规则理论若想成为一门真正的"科学的艺术",它就必须为内生利率规则寻找到一个坚固的微观基础。本文梳理评述了利率规则理论在经验上和理论上的成就和不足。
