On the desirability of nominal GDP targeting

This paper evaluates the welfare properties of nominal GDP targeting in the context of a New Keynesian model with both price and wage rigidity. In particular, we compare nominal GDP targeting to inflation and output gap targeting as well as to a conventional Taylor rule. These comparisons are made on the basis of welfare losses relative to a hypothetical equilibrium with flexible prices and wages. Output gap targeting is the most desirable of the rules under consideration, but nominal GDP targeting performs almost as well. Nominal GDP targeting is associated with smaller welfare losses than a Taylor rule and significantly outperforms inflation targeting. Relative to inflation targeting and a Taylor rule, nominal GDP targeting performs best conditional on supply shocks and when wages are sticky relative to prices. Nominal GDP targeting may outperform output gap targeting if the gap is observed with noise, and has more desirable properties related to equilibrium determinacy than does gap targeting.     

Asset price targeting in an open economy with cognitive limitations: The best for macroeconomic and financial stability?

The choices of policy targets and the formation of agent expectations have been critical issues addressed by monetary policy management since the financial crisis of 2008. This paper evaluates macroeconomic stability in a new Keynesian open economy in which agents experience both cognitive limitations and asset market volatility. The (im)perfect credibility of various monetary policies (e.g., a Taylor-type rule with- or without asset price targeting, strict domestic inflation targeting, strict CPI inflation targeting, and exchange rate peg) may lead agents to react according to their expectation rules, and thus create various degrees of booms and busts in output and inflation. Simulations confirm that a Taylor-type CPI inflation targeting including an asset price target is the best choice. In contrast, the business cycles induced by Keynesian “animal spirits” are enhanced by strict inflation targeting. Furthermore, a credible exchange rate pegging system with an international reserve pooling arrangement can improve social welfare and stability in an open economy, even though its absolute value of the loss function is slightly lower than a Taylor-type CPI inflation targeting including an asset price target.     

Can inflation targeting reduce price information asymmetry and alleviate corruptive behavior? Evidence from developing countries

This paper examines the role of inflation targeting as a price signaling mechanism reducing price information asymmetry and potentially reducing incentives for corruptive actions through its direct control on the inflation rate, thus simultaneously increasing institutional quality. The obtained evidence suggests that adopting inflation targeting lowers corruption in a sample of 61 developing countries for the period between 1990 and 2018. Countries that have adopted inflation targeting experience lower corruption levels, as measured by the corruption perceptions (CP) index, controlling for other relevant determinants of corruption identified in the empirical literature, such as inflation, level of income, income distribution, trade openness and the rule of law. This result is sensitive to the type of inflation targeting adopted. Soft (unofficial) inflation targeting has no significant effect on the corruption level, giving support to the claim that strong institutional commitment, accompanied by transparency and constant communication with regards to inflation targets by the central bank, provides an adequate price signaling mechanism. In addition, the analysis provides evidence that an efficient rule of law reduces corruption levels significantly, although its effects are rather modest to support the claims that it can solely lessen corruptive behavior in the sample of developing countries.     

THERE'S MANY A SLIP…

There has to be a General Election at some time in the next eighteen months. It has long been clear that the economy will not be in the best of shape in time for the election and that the best the Conservatives can hope for is a significant reduction in inflation and interest rates together with modest output growth. Our October forecast suggested that this combination was feasible and that the government would be able to go to the country with base rates of 12 per cent, retail price inflation at half its present level and output growing at a rate of 2per cent after a relatively short and shallow recession. It may turn out that this is an overly optimistic central forecast and in this Forecast Release we examine some of the ways in which it could go wrong. In a worst possible scenario the government may have to face the electorate with the economy in recession, inflation high and interest rates still at or close to their present levels.     

Bounded interest rate feedback rules in continuous-time

This paper analyzes the dynamic consequences of interest rate feedback rules in a flexible-price model where money enters the utility function. Two alternative rules are considered based on past or predicted inflation rates. The main feature is to consider inflation rates that are selected over a bounded time horizon. We prove that if the Central Bank's forecast horizon is not too long, an active and forward-looking monetary policy is not destabilizing: the equilibrium trajectory is unique and monotonic. This is an advantage with respect to active and backward-looking policies that are shown to lead to a unique but fluctuating dynamic.     

Inflation and interest rate derivatives for FX risk management: Implications for exporting firms under real wealth

Firms that export goods face risks such as product price, cost, and exchange rate risks. Price and cost risks can substantially reduce the FX hedging performance in real wealth. We thus investigate hedging strategies that are intended to improve the performance of the FX hedge in real terms using inflation and interest rate derivatives. The impact of these additional instruments is not clear and has only been briefly analyzed in the hedging literature so far. For this purpose, we derive variance-minimizing hedge positions of an exporting firm. A cointegrated VAR and bootstrap methods are used to evaluate the efficiencies of several hedging strategies. While inflation derivatives work better in the short run, interest rate derivatives perform better over longer hedge horizons.     

Band or point inflation targeting? An experimental approach

We conduct laboratory experiments with human subjects to test the rationale of adopting a band versus point inflation targeting regime. Within the standard New Keynesian model, we evaluate the macroeconomic performances of both regimes according to the strength of shocks affecting the economy. We find that when the economy faces small uncorrelated shocks, the level of inflation as well as its volatility are significantly lower in a band targeting regime, while the output gap and interest rate levels and volatility are significantly lower in a point targeting regime with tolerance bands. However, when the economy faces large uncorrelated shocks, choosing the suitable inflation targeting regime is irrelevant because both regimes lead to comparable performances. These findings stand in contrast to those of the literature and question the relevance of clarifying a mid-point target within the bands, especially in emerging market economies more inclined to large and frequent shocks.     

STABILISATION POLICY,RATIONAL EXPECTATIONS AND PRICE‐LEVEL VERSUS INFLATION TARGETING: A SURVEY

We survey literature comparing inflation targeting (IT) and price‐level targeting (PT) as macroeconomic stabilisation policies. Our focus is on New Keynesian models and areas that have seen significant developments since Ambler's (2009, Price‐level targeting and stabilisation policy: a survey. Journal of Economic Surveys 23(5): 974–997) survey: optimal monetary policy; the zero lower bound; financial frictions and transition costs of adopting a PT regime. Ambler's conclusion that PT improves social welfare in New Keynesian models is fairly robust, but we note an interesting split in the literature: PT consistently outperforms IT in models where policymakers commit to simple Taylor‐type rules, but results in favour of PT when policymakers minimise loss functions are overturned with small deviations from the baseline model. Since the beneficial effects of PT appear to hang on the joint assumption that agents are rational and the economy New Keynesian, we discuss survey and experimental evidence on rational expectations and the applied macro literature on the empirical performance of New Keynesian models. Overall, the evidence is not clear‐cut, but we note that New Keynesian models can pass formal statistical tests against macro data and that models with rational expectations outperform those with behavioural expectations (i.e. heuristics) in direct statistical tests. We therefore argue that policymakers should continue to pay attention to PT.     

An Econometric Analysis of Polish Inflation Dynamics with Learning about Rational Expectations

Rational expectations modelling has been criticized for assuming that economic agents can learn quickly about and compute rational price expectations. In response, various authors have studied theoretical models in which economic agents use adaptive statistical rules to develop price expectations. A goal of this literature has been to compare resulting learning equilibria with rational expectations equilibria. The lack of empirical analysis in this literature suggests that adaptive learning makes otherwise linear dynamic models nonlinearly intractable for current econometric technology. In response to the lack of empirical work in this literature, this paper applies to post-1989 monthly data for Poland a new method for modelling learning about price expectations. The key idea of the method is to modify Cagan’s backward-looking adaptive-expectations hypothesis about the way expectations are actually updated to a forward-looking characterization which instead specifies the result of learning. It says that, whatever the details of how learning actually takes places, price expectations are expected to converge geometrically to rationality. The method is tractable because it involves linear dynamics. The paper contributes substantively by analyzing the recent Polish inflation, theoretically by characterizing learning, and econometrically by using learning as a restriction for identifying (i.e., estimating wth finite variance) unobserved price expectations with the Kalman filter. This revised version was published online in July 2006 with corrections to the Cover Date.     

WORLD OUTLOOK

The recent weakness of the world economy does not undermine the relatively optimistic forecast for 1987 which we presented in May. At that time we suggested that activity would be sluggish for most of this year as a result of the impact effect of the OPEC III oil price collapse. But we also argued that by the end of the year there would be clear signs of a consumer-led recovery as the personal sector adjusted to the real income gains and lower inflation benefits of the lower oil price and the reduction in nominal interest rates which followed. There is mounting evidence of rising consumer spending, particularly in Europe and it is something of a puzzle that output has not risen to meet this demand. The explanation is partly that producer confidence has lagged behind that of consumers, so that demand has been met from stock, and partly that spending has been supplied from countries outside the OECD, especially the NICs in the Far East. Nevertheless, we are convinced that our earlier view of OECD output prospects next year remains the most likely though, in recognition of the growing importance of non-OECD competition, we have adjusted the output forecast down slightly. OECD GNP is expected to rise 2.6 per cent this year, with an acceleration to over 4 per cent in 1987 arid 1988. Moreover, we believe this can be achieved without a rebound in inflation, which is forecast to be stable at about its present level of 2 1/2 per cent.     

Economic Outlook 1991–1995: The London Business School with Gower Publishing: Forecast Release: THE CHANCELLOR'S ECONOMIC ADVICE

Within the last month the Chancellor has made two important speeches on macroeconomic policy. The first, to Surrey businessmen in June, pledged the UK to the French route to a ‘virtuous circle of low inflation, rising competitiveness and increasing market share’; the second, in July to the European Policy Forum, vigorously defended his present policy against the alternatives, which he dismissed as ‘illusory or destined to fail’, of devaluation or cutting interest rates. On both occasions Mr. Lamont placed the permanent conquest of inflation at the centre of his policy, arguing that holding sterling at its present central parity of DM 2.95 is the only way to achieve this objective. In his view the consequence of any of the alternative proposals would be ‘either higher interest rates, higher inflation, or most likely both’. In this Forecast Release we consider these claims and the economic advice on which it is based. On the latter we would surmise that the thrust of the advice which Mr. Lamont is receiving is that he has the opportunity to deliver a sustainably low inflation rate and that this requires a stable pound within the ERM. The alternatives involve a sterling devaluation which, no matter how obtained, would obstruct the goal of permanently low inflation in return for only transient benefits on output and unemployment. But the price of defeating inflation has been high and is not yet fully paid. Moreover the goalposts have been moved: to reach the French position on competitiveness, which underpins their gains in market share and which has taken the best part of a deeade to achieve, requires a still better inflation performance on the part of the UK and while this is being achieved, adjustment costs will persist. It is partly in defence of his own policies and partly in an attempt to moderate the already-high adjustment costs that Mr. Lamont has adopted a more combative stance. His advice is that to compete with Europe, we cannot award ourselves pay increases far in excess of European levels, indeed we need a period of below-average pay rises.     

A tale of two correlations: Evidence and theory regarding the phase shift between the price level and output

We examine the relationship between the price level and output at business-cycle frequencies. In the postwar period, there is evidence of a phase shift between the price level and output. Such a phase shift is manifested in the price level being countercyclical and the inflation rate being procyclical or acyclical, depending on the detrending method used. Our examination takes three approaches. First, we apply bootstrapping methods to characterize the two correlations, though the methodology could easily be extended to any set of facts. Second, we specify a model economy with forecast heterogeneity, showing numerically that this model economy can match the observed pair of correlations. Third, we apply robust control theory, deriving conditions in which the price level is countercyclical and the inflation rate is procyclical.     

How does interest rate policy affect inflation? A simple general equilibrium model with the interest rate as the policy instrument

This paper analyses the connection between the assumptions often made on the utility functions of economic agents when general equilibrium is considered. Concretely, we analyse the effect of certain assumptions regarding the elasticity of marginal utility for both the existence of equilibrium and, assuming equilibrium exists, for the effect that raising the nominal interest rate has on the equilibrium inflation rate. Typical macroeconomic wisdom states that an increase in the interest rate will decrease inflation, and this seems to have been the basis for real-life macroeconomic policy in several countries. However, this wisdom is based on models in which the money supply, and not the interest rate, is the policy instrument. Using a very simple general equilibrium model of intertemporal consumption, this paper finds sufficient conditions for the negative relationship to hold (and for it not to hold) in the short run, when monetary policy is characterised by a given nominal interest rate. Above all, it is shown how the relative risk aversion characteristics that are assumed of the economic agents are important.     

Monetary policy,housing rents,and inflation dynamics

In this paper we study the effect of monetary policy shocks on housing rents. Our main finding is that, in contrast to house prices, housing rents increase in response to contractionary monetary policy shocks. We also find that, after a contractionary monetary policy shock, rental vacancies and the homeownership rate decline. This combination of results suggests that monetary policy may affect housing tenure decisions (own versus rent). In addition, we show that, with the exception of the shelter component, all other main components of the consumer price index (CPI) either decline in response to a contractionary monetary policy shock or are not responsive. These findings motivated us to study the statistical properties of alternative measures of inflation that exclude the shelter component. We find that measures of inflation that exclude shelter have most of the statistical properties of the widely used measures of inflation, such as the CPI and the price index for personal consumption expenditures, but have higher standard deviations and react more to monetary policy shocks. Finally, we show that the response of housing rents accounts for a large proportion of the “price puzzle” found in the literature.     

House Prices, Housing Investment and Demography Forecasts from the LBS/Abbey National Model of the UK Housing Market

A new housing sector has been incorporated into the London Business School model. This article outlines the new housing model, summarizes the research which has gone into its construction, and presents a forecast of the UK housing market. Using the new housing model, we forecast a moderate recovery in the housing market in the later part of 1991 and 1992. This recovery is however short-lived and does not result in such high rates of house price increase as previous house price booms (Chart 1).
Cuts in interest rates following entry to the exchange rate mechanism of the EMS prompt a recovery in house prices from the middle of 1991. House price inflation then peaks with an increase in average UK house prices in 1992 of 11 per cent over the previous year. Increases in real personal disposable income are modest, by the standards of the 1980s, and for this reason the recovery does not develop the momentum of previous house price booms. House price inflation moderates again in 1993 falling back to around 7 per cent. Housing starts and housing investment recover only slightly from their present depressed levels.
the recovery in house prices is weaker than that foreseen in our April Forecast Release. This is because real personal disposable income is now forecast to grow more slowly during 1991. Sterling's membership of the ERM is followed by a fall in interest rates, but it is the timing of interest rate cuts rather than their magnitude which differs from the earlier forecast. The changed profile of interest rates has altered the house price forecast only marginally.     

Monetary Policy Rules, Policy Preferences, and Uncertainty: Recent Empirical Evidence

We survey recent empirical evidence on monetary policy rules, and find that the emphasis in the political economy literature on institutional design (e.g. central bank independence and inflation targeting) is exaggerated. Formal institutional reform seems neither a necessary nor a sufficient condition for the observation of shifts in monetary policy rules. However, there is no doubt that in some cases (e.g. the UK following the start of inflation targeting in 1992, and Bank of England Independence in 1997), a major shift in monetary policy conduct is detectable. We also highlight the problems in explicitly testing the predictions of the political economy literature. Semi-structural modelling approaches, such as time-varying VAR models may be more useful in understanding policy rules, and the interaction between policy shifts and changes in the transmission mechanism.     

Inferring Policy Objectives from Economic Outcomes*

Estimated policy rules are reduced‐form equations that are silent on many important policy questions. However, a structural understanding of monetary policy can be obtained by estimating a policymaker's objective function. The paper derives conditions under which the parameters in a policymaker's policy objective function can be identified and estimated. We apply these conditions to a New Keynesian sticky‐price model of the US economy. The results show that the implicit inflation target and the relative weight placed on interest rate smoothing both declined when Paul Volcker was appointed Federal Reserve chairman.

Alternative monetary policies and fiscal regime in new EU members

I investigate the relevance of a fiscal regime for disinflation in new EU member states (NMS). I generalize the framework of [Obstfeld, M., Rogoff, K., 1995. Exchange rate dynamics redux. Journal of Political Economy 103, 624–660] to incorporate the non-Ricardian fiscal regime and two monetary feedback rules: inflation targeting and depreciation targeting. Euro accession requires disinflation and stabilization of the exchange rate and thus restrictive monetary policy. The model illustrates that a sustainable and prudent fiscal policy is a necessary condition for successful stabilization of inflation. Thus, the lack of prudent fiscal policy, through its effects on inflation, may undermine the EMU accession of large NMS even when their fiscal outcomes fall within the Maastricht range.
