Forward-Looking Rules for Monetary Policy

This paper evaluates a class of simple monetary policy rules which feed back from explicit forecasts of future inflation - inflation forecast-based (IFB) rules. These rules aim to mimic current monetary policy practices among the inflation-targeting countries, where policy decisions are based on inflation forecasts. The rules themselves are evaluated using simulations from a small, rational expectations, open-economy macro-model. IFB rules are found to perform well in comparison with other simple rules, such as the Taylor rule. The reasons for this are: first, because they embody the lags in monetary transmission, aligning explicitly the control and the feedback variables of the policymaker; second, because IFB rules are capable of smoothing output by as much as is possible with rules which target output directly - for example, through variations in the forecast horizon; and third, because IFB rules implicitly condition on all state variables, and thus are information-efficient. For these reasons, inflation-targeting rules with an explicitly forward-looking dimension are found to take us within reach of the fully-optimal rule.

Optimal Horizons for Inflation Targeting

In this paper we investigate the problem of selecting an optimal horizon for inflation targeting in the United Kingdom. Since there are two key ways of thinking about an optimal horizon, we look at optimal horizons for both of these interpretations. In addition, to see whether our results are robust in the face of model uncertainty, we compute optimal horizons for two different models with divergent structural and dynamic characteristics.

Successful Austerity in the United States, Europe and Japan

The output effects of 2009 fiscal expansions have been hotly debated. But the discussion of fiscal multipliers is even more relevant now that several European countries have had to quickly retract their stimulus measures in an effort to regain market confidence. Using regime-switching VARs we estimate the impact of fiscal adjustment on the United States, Europe and Japan allowing for fiscal multipliers to vary across recessions and booms. We also estimate ex ante probabilities of recessions derived in association with different-sized and different types of consolidation shocks (expenditure- versus tax-based). We use these estimates to understand how consolidations should be designed to be most effective in terms of permanently and rapidly reducing a country’s debt-to-GDP ratio. The main finding is that smooth and gradual consolidations are to be preferred to frontloaded or aggressive consolidations, especially for economies in recession facing high risk premia on public debt, because sheltering growth is key to the success of fiscal consolidation in these cases.

The Lag from Monetary Policy Actions to Inflation: Friedman Revisited

This paper updates and extends Friedman’s (1972) evidence on the lag between monetary policy actions and the response of inflation. Our evidence is based on UK and US data for the period 1953–2001 on money growth rates, inflation, and interest rates, as well as annual data on money growth and inflation. We reaffirm Friedman’s result that it takes over a year before monetary policy actions have their peak effect on inflation. This result has persisted despite numerous changes in monetary policy arrangements in both countries. Similarly, advances in information processing and in financial market sophistication do not appear to have substantially shortened the lag. The empirical evaluation of dynamic general equilibrium models needs to be extended to include an assessment of these models’ ability to account for the monetary transmission lags found in the data.

Hybrid Inflation and Price-Level Targeting

In this paper we investigate the properties of monetary regimes that combine price-level and inflation targeting. We look both at an optimal control and at a simple rule characterisation of these regimes. We derive numerical results by modelling the economy as a small-scale open-economy RE model calibrated on UK data. We conclude that: (1) the relative merits of price-level and inflation targeting, as well as of mixes of these two, depend on particular modelling and policy assumptions; and (2) these merits do not always change gradually and/or monotonically as we move from one regime to another.

Indeterminacy with Inflation-Forecast-Based Rules in a Two-Bloc Model

We examine the performance of forward-looking inflation-forecast-based rules in open economies. In a New Keynesian two-bloc model, a methodology first employed by Batini and Pearlman (2002) is used to obtain analytically the feedback parameters/horizon pairs associated with unique and stable equilibria. Three key findings emerge: First, indeterminacy occurs for any value of the feedback parameter on inflation if the forecast horizon lies too far into the future. Second, the problem of indeterminacy is intrinsically more serious in the open economy. Third, the problem is compounded further in the open economy when central banks respond to expected consumer, rather than producer price inflation.

A Dynamic Monetary Conditions Index for the UK

Abstract Monetary Conditions Indices (MCIs) are weighted-averages of changes in an interest rate and an exchange rate relative to their values in a base period. A few central banks calculate MCIs for use in monetary policy. Although the Bank of England does not calculate such an index, several international organizations as well as financial corporations construct MCIs for the UK on a regular basis. In this article, we survey those indices and compare their performance. We also suggest an alternative MCI for the UK to be used as a coincident indicator of stance, obtained by estimating and simulating a small-scale macro-econometric model over the period 1984 Q4–1999 Q3. To overcome familiar criticisms of MCIs, our measure innovates upon existing MCIs in several respects. In this sense it may be more informative than those in understanding whether an existing level of interest rates, given the existing level of sterling, makes monetary policy ‘tighter’ or ‘looser’ than in previous periods.

Achieving and Maintaining Price Stability in Nigeria

This paper reviews the historical performance of monetary policy in Nigeria and discusses the relative merits of alternative monetary policy strategies that Nigeria could adopt in the future, once the many operational issues that today obstruct the conduct of monetary policy have been addressed. An analysis of external and fiscal dominance in Nigeria reveals that none of the candidate strategies is particularly appealing although, on various grounds, a long-run target for inflation combined with a free float seems to be the ultimate option. The paper shows how to design and operationalize such a regime in Nigeria when account is taken for the emerging market features of the economy.

A Simple Method to Compute Fiscal Multipliers

Fiscal multipliers are important tools for macroeconomic projections and policy design. In many countries, little is known about the size of multipliers, as data availability limits the scope for empirical research. For these countries, we propose a simple method—dubbed the “bucket approach”—to come up with reasonable multiplier estimates. The approach bunches countries into groups (or “buckets”) with similar multiplier values, based on their characteristics. It also takes into account the effect of some temporary factors, such as the state of the business cycle.

Informal Labour and Credit Markets: A Survey

This paper reviews the literature on the informal economy, focusing first on empirical findings and then on existing approaches to modeling informality within both partial and general equilibrium environments. We concentrate on labour and credit markets, since these tend to be most affected by informality. The phenomenon is particularly important in emerging and other developing economies, given their high degrees of informal labour and financial services and the implications these have for the effectiveness of macroeconomic policy. We emphasize the need for dynamic general equilibrium (DGE) and ultimately dynamic stochastic general equilibrium (DSGE) models for a full understanding of the costs, benefits and policy implications of informality. The survey shows that the literature on informality is quite patchy, and that there are several unexplored areas left for research.
