On the dominance of the Keynesian regime in disequilibrium growth theory: A note

This note shows that non-Walrasian disequilibrium models of monetary growth (which are rare) can be considerably simplified in their dynamics if appropriate flexibilities of market economies are taken into account that help to avoid certain types of rationing of economic agents as they are typical for the non-Walrasian modeling of macrodynamics. We consider and modify accordingly an established example of this type of model building and show that propositions on stability and the loss of stability of the then remaining Keynesian regime are much easier to derive and also much more transparent than in their original non-Walrasian setup with its regime switches right at the steady state of the economy.     

Budget uncertainty in a monetary union

Governments in a monetary union fear spending disturbances. We distinguish them according to their ability to hedge against these disturbances and assume that they derive their optimal fiscal decisions by using a robust control approach. Results show that governments being highly vulnerable to spending disturbances set excessive tax rates, thereby exacerbating the fiscal pressure detrimental to output and obliging the central bank to conduct an expansionary monetary policy. Countries whose governments have higher ability to hedge against spending disturbances then suffer from the inflationary consequences of this monetary policy.     

The Optimal Inflation Tax

We determine the second best rule for the inflation tax in monetary general equilibrium models where money is dominated in rate of return. The results in the literature are ambiguous and inconsistent across different monetary environments. We derive and compare the optimal inflation tax solutions across the different environments and find that Friedman's policy recommendation of a zero nominal interest rate is the right one.Journal of Economic LiteratureClassification Numbers: E31, E41, E58, E62.     

BLOCS, ZONES AND BANDS: INTERNATIONAL MONETARY HISTORY IN LIGHT OF RECENT THEORETICAL DEVELOPMENTS

Trends in international finance in recent decades have inspired considerable research on bloc- and band-based international monetary arrangements. From this literature have emerged models providing the basis for much recent work in international monetary economics. To date, however, their application to historical experience has been rare. We therefore highlight parallels between modern-day target zones on the one hand and the classical and inter-war gold standards and Bretton Woods System on the other. We suggest that bloc-based international monetary arrangements are in fact an historical commonplace; they have been the rule rather than the exception.     

Two-period cycles in a three-period overlapping generations model

We study the properties of two-period monetary cycles in simple pure exchange overlapping generations economies in which the households live for three periods. We demonstrate that these economies can support cycles under a much broader—and, arguably, more plausible—range of assumptions than the analogous two-period economies. We show that economies that fail the well-known Grandmont (Econometrica 53 (1985) 995) condition can have cycles, and that economies that satisfy the condition can fail to have cycles. In addition, we show that economies can have monetary cycles when they do not have conventional monetary steady states, and when aggregate demand for assets is not decreasing in the real return rate at a gross real rate of unity.     

On winning forecasting competitions in economics

To explain which methods might win forecasting competitions on economic time series, we consider forecasting in an evolving economy subject to structural breaks, using mis-specified, data-based models. ‘Causal’ models need not win when facing deterministic shifts, a primary factor underlying systematic forecast failure. We derive conditional forecast biases and unconditional (asymptotic) variances to show that when the forecast evaluation sample includes sub-periods following breaks, non-causal models will outperform at short horizons. This suggests using techniques which avoid systematic forecasting errors, including improved intercept corrections. An application to a small monetary model of the UK illustrates the theory.     

The asymmetric effects of investor sentiment and monetary policy on stock prices

We examine the impact of investor sentiment and monetary policy on the stock prices under different market states based on the Markov-switching vector autoregression (MS-VAR) model. The results show that the sentiment shocks, more than monetary policy shocks, lead to not only much larger fluctuations of stock prices but also much longer duration in the stock market downturn than in the stock market expansion, which shows obvious asymmetric effect. Moreover, the responses of stock prices to the sentiment shocks present an immediate effect, while the responses of stock prices to the monetary policy shocks show one-period lag effect.     

Monetary policy transmission mechanisms in Serbia: evidence from the fully-fledged inflation targeting regime

This article examines the effectiveness of monetary transmission mechanisms in the Serbian economy, covering the period from January 2009 (the point at which the formal switch to the fully-fledged inflation targeting regime was made) to December 2013. The results of the recursive VAR models suggest that the exchange rate and credit channels play a major role in the monetary transmission process, whereas this is not true in the case of the interest rate channel. However, the results of the non-recursive VAR models show that the role of the exchange rate has diminished over time. On the other hand, the credit channel has become much more influential. Thus, if one of the overriding objectives of adopting the explicit inflation targeting regime is to enhance the importance of other channels apart from the exchange rate channel, which could make monetary policy more effective in achieving price and financial stability, the switch to the inflation targeting regime is justified.     

Stabilization of the balance of payments in a small,planned economy,with an application to ethiopia

We construct a macroeconomic model of a planned economy and derive a currency basket that will stabilize the current account. The exchange rate is incorporated in a monetary system so as to derive consistent money and price targets. If the planners have access to foreign loans, they may target a negative current account. The model is estimated for Ethiopia. Having derived weights for the currency basket corresponding to 1980, a simulation is carried out in which macroeconomic targets for 1980 are derived, based on past information.     

An inventory of simple monetary policy rules in a New Keynesian macroeconomic model

We derive necessary and sufficient conditions for simple monetary policy rules that guarantee equilibrium determinacy in the New Keynesian monetary model. Our modeling framework is derived from a fully specified optimization model that is amenable to analytical characterisation. The monetary rules analyzed are variants of the basic Taylor rules ranging from simple inflation targeting (current, forward, backward) to canonical Taylor rules with and without inertial nominal interest rates. We establish that determinacy obtains for a wide range of policy parameters, especially when the monetary authority targets output and smoothes interest rates. Contrary to other results in the literature, we do not find a case for super-inertial interest rate policy.     

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.     

Capital Controls,Global Liquidity Traps,and the International Policy Trilemma*

The zero bound on interest rates introduces a new dimension to the trilemma in international policy. The openness of the international financial market might render monetary policy ineffective, even within a system of fully flexible exchange rates, because shocks that lead to a liquidity trap in one country are propagated through financial markets to other countries. However, the effectiveness of monetary policy can be restored by the imposition of capital controls. We derive the optimal response of monetary policy to a global liquidity trap in the presence of capital controls. We show that, even though capital controls might facilitate effective monetary policy, capital controls are not generally desirable in terms of welfare.     

The design of monetary and fiscal policy: A global perspective

We study the emergence of multiple equilibria in models with capital and bonds under various monetary and fiscal policies. We show that the presence of capital is indeed another independent source of local and global multiplicities, even under active policies that yield local determinacy. We also show how a very similar mechanism generates multiplicities in models with bonds and distortionary taxation. We then explore the design of monetary policies that avoid multiple equilibria. We show that interest rate policies that respond to the output gap, while potentially a source of significant inefficiencies, may be effective in preventing multiple equilibria and costly oscillatory equilibrium dynamics.     

Some Thoughts on Monetary Targeting vs. Inflation Targeting

We offer some empirical evidence on the likely scale of control and indicator problems surrounding alternative monetary targets and a direct inflation target. The links between monetary policy actions and inflation are estimated in dynamic linear models using the Kalman filter. We compare alternative intermediate-target and final-target monetary strategies using German data from the end of the Bretton Woods system until 1997. The estimation results show that broad money dominates narrow money as an intermediate target, while control problems involved in targeting broad money are larger than for direct inflation targets.     

The optimal neglect of inflation: An alternative interpretation of UK monetary policy during the “Great Moderation”

This paper argues that UK monetary policymakers did not respond to the inflation rate during most of the “Great Moderation” that ran from the early 1990s to the mid-2000s. We derive a generalisation of the New Keynesian Phillips curve in which inflation is a non-linear function of the output gap and show that the optimal response of the policy rule to inflation depends on the slope of the Phillips curve; if this is flat, manipulation of aggregate demand through monetary policy does not affect inflation and so policymakers cannot affect inflation. We estimate the monetary policy rules implied by a variety of alternative Phillips curves; our preferred model is based on a Phillips curve that is flat when output is close to equilibrium. We find that policy rates do not respond to inflation when the output gap is small, a situation that characterised most of the “Great Moderation” period.     

Do the ECB's introductory statements help predict monetary policy? Evidence from a tone analysis

In this paper, we examine whether a tone shock derived from European Central Bank communication helps predict ECB monetary policy decisions. To this purpose, we first use a bag-of-words approach and several dictionaries on the ECB's Introductory Statements to derive a measure of tone. Next, we orthogonalise the tone measure on the latest data available to market participants to compute the tone shock. Finally, we relate the tone shock to future ECB monetary policy decisions. We find that the tone shock is significantly and positively related to future ECB monetary policy decisions, even when controlling for market expectations of monetary policy and the Governing Council's inter-meeting communication. Further extensions show that the predictive ability of the tone shock is robust to (i) the normalization of the tone measure, (ii) alternative market expectations of monetary policy, and (iii) the horizon of macroeconomic variables used in the Taylor-type monetary policy rule. These findings highlight an additional channel through which ECB communication improves monetary policy predictability, suggesting that the ECB may have private information that it communicates through its Introductory Statements.     

Money,activity and prices: Some inter-country evidence

The paper explores the relationships between monetary variables and real economic activity and prices in the six largest industrialized economies. Univariate and multivariate time series forecasting models are used to break down monetary policy variables into anticipated and unanticipated components. Overall monetary policy variables, particularly domestic credit expansion, appear to be significant leading indicators for subsequent real economic activity and prices. Additionally, anticipated components of monetary policy are shown to have as much forecasting ability for subsequently realized economic variables as unanticipated components. This does not appear to be consistent with the implications of pure rational expectations models. It was also noted that results differed significantly according to the choice of monetary variable and across individual countries. In particular the results implied no contradiction with previous findings for the impact of unanticipated money supply in the U.S., though such contradictions would have appeared if DCE had been used as the monetary variable.     

On the non-neutrality and optimality of monetary policy when financial markets are incomplete: a macroeconomic perspective

We study in this paper a simple model of a two-period economy, with two states of the world in the second period, two agents and one good. Financial markets are incomplete since only inside money is available. We show that outside money, which is introduced in the model through its role as a medium of exchange, is non-neutral, in the sense that it has an effect on the equilibrium allocation. We then discuss whether a monetary policy that would aim at state-independent price levels is desirable. We illustrate that discussion with a few examples. The possible sub-optimality of a constant-across-states inflation rates target for monetary policy is to be contrasted with results from representative agent macroeconomic models.     

Monetary policy effectiveness and stock market cycles in ASEAN-5

This article examines the asymmetric effects of monetary policy on real output in bull and bear phases of stock market in five ASEAN economies (Malaysia, Singapore, Indonesia, the Philippines and Thailand) using the recently developed pooled mean group (PMG) technique. Stock market cycles are identified by employing Markov switching models and the rule-based nonparametric approach. Estimating the models using monthly data from 1991:1 to 2011:12, the results show that monetary policy (measured by short-term interest rate) has a negative and statistically significant long-run effect on real output in bull and bear market periods while the effects are stronger in bear periods than bulls. In the short run, there is no statistically significant relationship between monetary policy and real output. These results are consistent with finance constraints (capital market imperfection) models that predict that monetary policy is more effective during bear periods than bulls.
