On the Effectiveness of Monetary Policy and of Fiscal Policy

There has been a major shift within macroeconomic policy over the past two decades or so in terms of the relative importance given to monetary policy and to fiscal policy in both policy and theoretical terms. The former has gained considerably in importance, with the latter being rarely mentioned. Furthermore, the nature of monetary policy has shifted away from any attempt to control some monetary aggregate (prevalent in the first half of the 1980s), and instead monetary policy has focused on the setting of interest rates as the key policy instrument. There has also been a general shift towards the adoption of inflation targets and the use of monetary policy to target inflation. This paper considers the significance of this shift in the nature of monetary policy. This enables us to question the effectiveness of monetary policy, and to explore the role of fiscal policy. We examine these questions from the point of view of the "new consensus" in monetary economics and suggest that it is rather limited in its analysis. When the analysis is broadened out to embrace empirical issues and evidence the clear conclusion emerges that monetary policy is relatively impotent. The role of fiscal policy is also considered, and we argue that fiscal policy (under specified conditions) remains a powerful tool for macroeconomic policy. This is particularly an apt conclusion under current economic conditions.     

MONETARY AND FISCAL POLICY EFFICIENCY AND COORDINATION IN A MULTI‐SECTOR OPEN‐ECONOMY GENERAL EQUILIBRIUM MODEL

The paper analyzes monetary and fiscal stabilization and coordination in a multi‐sector stochastic new open economy macroeconomics (NOEM) model. It first aims to assess the capacity of fiscal and monetary policy to reduce or eliminate the negative welfare effects of an unanticipated productivity shock affecting some or all of the sectors in each country. Second, it evaluates the possible gains from international monetary cooperation as well as the impact of active fiscal policy on the welfare performance of monetary policy. The setup also allows for international asymmetry concerning the uncertainty over the shocks. The results show that monetary and fiscal policies are efficient tools of stabilization and under several conditions they can replicate the flexible‐price equilibrium. However, their welfare performance is not necessarily increased when both monetary and fiscal policies react to shocks at the national level. The existence of bilateral gains from monetary cooperation depends on the degree of asymmetry concerning the uncertainty over the shocks.     

Welfare cost of inflation in a stochastic balanced growth model

There is a large and growing literature on the welfare cost of inflation. However, work in this area tend to find moderate estimates of welfare gains. In this paper we reexamine welfare costs of inflation within a stochastic general equilibrium balanced growth model paying a particular attention to recursive utility, portfolio balance effects, and monetary volatility and monetary policy uncertainty. Our numerical analysis shows that a monetary policy that brings down inflation to the optimum level can have substantial welfare effects. Portfolio adjustment effects seem to be the dominant factor behind the welfare gains.     

BANK EFFICIENCY AND THE EFFECTIVENESS OF MONETARY POLICY

Advances in information technology and bank consolidation have altered the way banks operate by necessitating that banks control costs and provide services efficiently to remain competitive. Given the unique role bank operations play in the transmission of monetary policy, a key unresolved question is whether bank efficiency alters monetary policy outcomes. Using a stochastic frontier approach to measure cost‐efficiency and panel data of U.S. bank balance sheets, we show that banks with greater cost‐efficiency are more sensitive to monetary shocks.

Should monetary policy respond to asset price misalignments?

This paper analyses the relationship between monetary policy and asset prices using a structural rational expectations open economy model that allows for the effect of asset prices and exchange rates on aggregate demand. We assume that asset prices and exchange rates follow a partial adjustment mechanism whereas they are positively affected by past changes, thus allowing for ‘momentum trading’, while at the same time we allow for reversion towards fundamentals. We then conduct stochastic simulations using two alternative monetary policy rules, inflation-forecast targeting and the standard Taylor rule. The results indicate that, under both rules, interest rate setting that takes into account asset price misalignments leads to lower overall macroeconomic volatility, as measured by the postulated loss function of the central bank.     

An alternative monetary policy target

For most of the period since the mid-1970s, the Federal Reserve has expressed its monetary policy intentions by announcing the target growth rates of three principal monetary aggregates: the simple-sum M1, M2 and M3. However, the sweeping changes and the deregulation in the financial industry have greatly affected the relevance of these traditional monetary aggregates. The unusual behaviour of the simple-sum monetary aggregates has forced the Federal Reserve to stop setting target range for M1. The measuring of monetary aggregates has become a controversial question. This paper constructs the new-benchmark Divisia monetary indexes which reflect ‘moneyness’ more accurately than the old Divisia indexes. I demonstrate that the historical trends of the Divisia monetary indexes are sensitive to the brenchmark rates chosen in constructing these indexes. In addition, I compare the forecasting performance of the new-benchmark Divisia monetary indexes with the simple-sum and the old Divisia monetary indexes in the estimated money demand functions. I find that the new-benchmark Divisia monetary indexes provide the best statis forecasting performance. The result indicate that the new-benchmark Divisia monetary indexes should be considered as alternative measures of money in studying the relationship between money and the economy.     

The effects of monetary policy: a DSGE model analysis of Taiwan

This article attempts to use empirical data to analyse the impact of monetary policy in a dynamic stochastic general equilibrium model. According to the monetary policy decisions of the Central Bank of China (Taiwan), maintaining price, financial stability and fostering economic growth are the ultimate goals of monetary policy during the empirical period. First, this article uses the cointegration tests to determine the operating targets, the intermediate targets and the ultimate goals of monetary policy. Then, a forward-looking aggregate demand–aggregate supply model for a small open economy is specified, and policy discretion is included in this model. Finally, the model is estimated by a linear state space model and is used to analyse the short-run effects of a systematic monetary change.     

Monetary policy regimes and beliefs*

This article investigates the role of beliefs over monetary policy in propagating the effects of monetary policy shocks within the context of a dynamic, stochastic general equilibrium model. In our model, monetary policy periodically switches between low and high money growth regimes. When individuals are unable to observe the regime directly, they form inferences over regime‐type based on historical money growth rates. For an empirically plausible money growth process, beliefs evolve slowly in the wake of a regime change. As a result, our model is able to capture some of the observed persistence of real and nominal variables following such a regime change.     

Anticipated monetary and fiscal policy effects on output

This paper is a test of the LSW proposition. In a Sargent and Wallace model, two different formal money supply mechanisms are incorporated. One is based on the government budget restraint and the other on the Fed's reaction function. Neither is a pure feedback mechanism. The stochastic process of output is a function of the interaction of the monetary and fiscal policy parameters with the models' disturbances. Thus, the question of the LSW proposition comes down to an empirical issue. The models are then estimated by 3SLS. The results are not incompatible with the policy ineffectiveness proposition.     

The Case of European Monetary Integration and its Former Hegemon

There is no historical precedent for the institutional set‐up of the eurozone. However, it is an arrangement that could not and cannot escape the universal laws and principles of economics. This article tries to look generally at the consequences of this integration project from the perspective of the former monetary hegemon, Germany, whose hegemony largely ended as a result of the monetary integration method chosen. Those consequences are, of course, more apparent in bad times than they were in good times. We then specifically examine the problem of convergence and divergence within a currency area and discuss the issue of competitive devaluation. In the conclusion, we try to formulate the fundamental dilemma faced by the former monetary hegemon. Its solution will affect those inside and outside the integration project.     

Income redistribution during a disinflation

This paper estimates the income redistribution among different sectors of society that results from a government disinflation policy. A model of wage setting in the U.S. economy is developed and then simulated for alternative money growth paths and private-sector behavioral parameters. It is found that a sudden change in monetary policy can cause significantly more income redistribution than a slow monetary deceleration. The paper concludes that a monetary policy rule which generates greater price stability may encourage a wage-setting rule in which wages are more responsive to monetary policy.     

Bank behavior, incomplete interest rate pass-through, and the cost channel of monetary policy transmission

This paper employs a New Keynesian DSGE model to explore the role of banks within the cost channel of monetary policy transmission for shaping the interest rate pass-through from money market rates to loan rates. Banks extend loans to firms in an environment of monopolistic competition by setting their loan rates in a staggered way, which means that the adjustment of the aggregate loan rate to a monetary policy shock is sticky. We estimate the model for the euro area by adopting a minimum distance approach. Our findings exhibit that (i) financial costs are an important factor for price changes, (ii) frictions in the loan market have an effect on the propagation of monetary policy shocks as the pass-through from a change in money market rates to loan rates is incomplete, and (iii) the strength of the cost channel is mitigated as banks shelter firms from monetary policy shocks by smoothing loan rates.     

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.     

International monetary policy coordination: an evaluation using a large econometric model

We examine whether there is a case for coordinating monetary policy reactions across major economies. We undertake stochastic simulations on the National Institute's Global Econometric Model (NiGEM), to evaluate independently set monetary policy where domestic considerations remain the prime objective and we compare outcomes to a regime with a coordinated policy where domestic interest rates react to international conditions. We also demonstrate the asymptotic properties of the stochastic simulations and stress the robustness of our results.

Monetary policy and the role of inventory investment

In this article, we develop a dynamic stochastic general equilibrium (DSGE) model with sticky prices and inventory investment to explore the relationship between inventories and monetary policy. We use the traditional inventory literature as a basis to motivate this extension of the benchmark model and propose inventories as a factor of production. Within this setting, we test the empirical findings in the literature that, since the mid-1980s, monetary policy changed its target towards the inventory component of GDP. We explore this idea in our theoretical model and conclude through simulations that this is a plausible complementary explanation for the reduction in output volatility that was observed during the Great Moderation period.     

Bitcoin and entrepreneurship: breaking the network effect

This paper explores the question of whether the market process is capable of bringing about a spontaneous monetary switch to a new currency in the presence of strong network effects of the incumbent currency as well as the absence of contingencies such as extreme inflation or political instability. It does so by examining current happenings around Bitcoin. It finds that two mechanisms stand out: the coordinating efforts of the profit-maximizing entrepreneur as well as the ability to use the old and the new currency simultaneously. Specifically, it finds that marginal decisions made by rational agents merely seeking to maximize net private benefit irrespective of the network effect, be it entrepreneurs or users of the new currency, are capable of setting in motion a switch to a new currency. Whether or not these mechanisms play out fully in the case of Bitcoin still remains to be seen.     

Money and growth in a cash-in-advance economy with costly credit

This paper develops a stochastic growth model with a cash-in-advance constraint, costly credit, and intermediary services. We study how the behavior of financial intermediaries affects the relationship between economic growth and the monetary system. We show that the payment that intermediaries charge for providing financial services influences the money–growth relationship. When the intermediation cost increases proportionally with credit purchases, we do not observe any influence of growth on the monetary system. When the intermediation cost is not proportional to credit purchases, growth is responsible for a transformation of the monetary system, i.e. money is relatively driven out of the economy as the economy grows.     

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.
