Forecasting UK consumer price inflation using inflation forecasts

The inflation rate is a key economic indicator for which forecasters are constantly seeking to improve the accuracy of predictions, so as to enable better macroeconomic decision making. Presented in this paper is a novel approach which seeks to exploit auxiliary information contained within inflation forecasts for developing a new and improved forecast for inflation by modeling with Multivariate Singular Spectrum Analysis (MSSA). Unlike other forecast combination techniques, the key feature of the proposed approach is its use of forecasts, i.e. data into the future, within the modeling process and extracting auxiliary information for generating a new and improved forecast. We consider real data on consumer price inflation in UK, obtained via the Office for National Statistics. A variety of parametric and nonparametric models are then used to generate univariate forecasts of inflation. Thereafter, the best univariate forecast is considered as auxiliary information within the MSSA model alongside historical data for UK consumer price inflation, and a new multivariate forecast is generated. We find compelling evidence which shows the benefits of the proposed approach at generating more accurate medium to long term inflation forecasts for UK in relation to the competing models. Finally, through the discussion, we also consider Google Trends forecasts for inflation within the proposed framework.     

Econometric policy evaluation and expectations

Recently large-scale econometric models have been criticized as inappropriate tools for policy evaluation. One critical point often mentioned is the way expectations are formed. This paper shows that the way the process of expectations formation is considered does not play a crucial role. Instead, the ability to model agents' reactions to changes in policy is the essence of the critique. As long as government behaviour is sufficiently accessible in the model, applied econometrics may still use large-scale systems for which rational expectations solutions would be troublesome if not impossible to reach.     

Inflation targeting and inflation expectations in Mexico

In this article we analyse inflation expectations in Mexico. After a review of the theoretical and empirical literature, we apply unit root, normality and cointegration tests to the data provided by Banco de México (Banxico) in the Survey on the Expectations of the Private Sector Economics Specialists. Our results reject the null hypothesis of normality for inflation expectations over the period 2004:01–2011:12. The exchange rate has become one of the most relevant variables in the transmission mechanism of monetary policy in a small open economy. In this regard, we show the existence of a long-run relationship between nominal exchange rate and interest rate where inflation expectations matter for long-term dynamics.     

Inflation surprises and inflation expectations in the Euro area

In the second half of 2012, euro area inflation started declining and reached historical lows at the end of 2014. Market-based measures of inflation expectations also declined to unprecedented levels. During this disinflationary period, inflation releases have often surprised analysts on the downside. We provide evidence that inflation ‘surprises’ have significant effects on inflation expectations. The sensitivity of inflation expectations to the surprises, which has varied over time, disappeared after the introduction of the Asset Purchase Programme by the European Central Bank.     

Competitive equilibrium hyperinflation under rational expectations

This paper shows that a competitive equilibrium model, where a representative agent maximizes welfare, expectations are rational and markets are in equilibrium can account for several hyperinflation stylized facts. The theory is built by combining two hypotheses, namely, a fiscal crisis that requires printing money to finance an increasing public deficit and a predicted change in an unsustainable fiscal regime.We thank an anonymous referee for very helpful comments.

The expectations theory of the term structure: Evidence from inflation forecasts

This paper tests the joint hypothesis of rational expectations and the expectations theory of the term structure using the Livingston survey data on price inflation forecasts. For a variety of sample periods, the paper presents evidence that the data are consistent with the theory. Since inflation forecasts, unlike interest rates, are not linked to specific underlying financial assets, the relationship between longterm and short-term inflation forecasts should not embody risk premia. This paper's findings therefore lend support to the view that a time-varying risk premium is needed to explain the observed term structure of interest rates.     

The information content of market-based measures for the long-term inflation expectations of professionals: evidence from a midas analysis

Long-term inflation expectations taken from the Survey of Professional Forecasters are a major source of information for monetary policy. Unfortunately, they are published only on a quarterly basis. This article investigates the daily information content of market-based measures, such as inflation-linked swaps and breakeven inflation rates, for the next survey outcome. Using a mixed data sampling approach, we find that professionals account for the daily dynamics of market-based measures when they submit their long-term inflation expectations. We propose a daily indicator of professionals’ inflation expectations that outperforms alternative indicators that ignore the high-frequency dynamics of market-based measures. To illustrate the usefulness of the new indicator, we provide new evidence on the (re-)anchoring of U.S. inflation expectations.     

Decomposing household,professional and market forecasts on inflation: a dynamic factor model analysis

A dynamic factor model with stochastic volatility is used to investigate the relationships between three alternative measures of inflation expectations. The results show evidence of both a common time-varying trend and a common transitory component between inflation and short-term inflation expectations from households, professionals and markets. While the common time-varying trend has declined in both level and volatility since the early 1980s, it was found that consumer expectations are disproportionately influenced by the visibility of prices of select few goods. Roughly speaking, a 1% point increase in food and energy prices leads to about 1/3% point increase in consumer forecasts of inflation. In terms of policymaking, this finding suggests that stability in highly visible prices can moderate inflation in a meaningful way.     

Macroeconomic expectations and time varying heterogeneity:evidence from individual survey data

ABSTRACT

The goal of this paper is to investigate forecast heterogeneity and time variability in the formation of expectations using disaggregated monthly survey data on macroeconomic indicators provided by Bloomberg from June 1998 to August 2017. We show that our panel of forecasters are not rational and are moderately heterogeneous and thus confirm that previously well-established results on asset prices hold for macroeconomic indicators. We propose a flexible hybrid forecast model defined at any time as a combination of the extrapolative, regressive, adaptive and interactive heuristics. Controlling for endogenous structural breaks, we find that experts adjust their forecast behaviour at any time with some inertia in extrapolative and adaptive profiles. Changes in the formation of expectations are triggered mostly by financial shocks, and uncertainty is dealt with by using complex processes in which the fundamentalist component overweighs chartist activity. Forecasters whose models combine different relevant rules and display high temporal flexibility provide the most accurate forecasts. Authorities can then stabilize the domestic markets by encouraging fundamentalists’ forecasts through increased transparency policy.     

Money non-neutrality in a Rational Belief Equilibrium with financial assets

Summary. In Rational Beliefs Equilibria money is generically non-neutral. Given the expectational perspective proposed by the Theory of Rational Belief Equilibrium, we show that one of the most important factors in the emergence of money non-neutrality is played by Endogenous Uncertainty. This, in contrast to the Rational Expectations results of money neutrality and policy ineffectiveness, leads to a scenario in which monetary policy has an impact on the real economy and price volatility. The heterogeneity of beliefs together with the distribution and intensity of agents' states of optimism/pessimism can amplify the real effect of monetary policy and/or generate endogenous fluctuations in the economy which are not explained by any exogenous shock. We claim that money non-neutrality is mostly an expectations driven phenomenon. Indeed, additional assumptions of asymmetry of information and/or unanticipated monetary policy are not needed to explain the real effect of monetary policy as it is customary in the New Classical Theory.

German Monetary Union: An historical counterfactual analysis

This paper views German Monetary Union as a sequence of large asymmetric shocks to the European economies. As such it can be analysed with a large, new-Keynesian macro-econometric model of the relevant economies such as NiGEM. The ‘news’ in the sequence of shocks is assessed by analysing contemporary, NiGEM based, forecasts, and important events are then ‘peeled-off’ in reverse order. The resulting counterfactual history analyses the effects of the collapse of the Soviet economy on the EC and Scandinavian economies, and it is argued that the recession in countries such as Finland was not primarily caused by trade effects. The costs of support programmes for East Germany are then removed, creating a negative fiscal shock. Finally the paper analyses the overall effects of the set of shocks. In each part of the counterfactual history, individuals from forward looking expectations and the authorities operate fiscal solvency rules and target monetary aggregates.     

Non-implementation of rational expectations as a perfect Bayesian equilibrium

Summary. We point out several conceptual difficulties of the rational expectations equilibrium concept. In particular we show that such an equilibrium need not be incentive compatible and need not be implementable as a perfect Bayesian equilibrium . A comparison of rational expectations equilibria with the private core is also provided. We conclude that the private core is a more appropriate concept to capture the idea of contracts under asymmetric information.Received: 15 December 2003, Revised: 18 November 2004, JEL Classification Numbers: C71, C72, D5, D82.

On non-revealing rational expectations equilibrium

It is shown that a non-revealing rational expectations equilibrium may not be coalitionally Bayesian incentive compatible, may not be implementable as a perfect Bayesian equilibrium and may not belong to the weak fine core and thus may not be fully Pareto optimal. These negative results lead us to conclude the non-revealing rational expectations equilibrium is not a sensible solution concept. We wish to thank Dr A. Hadjiprocopis for his invaluable help with the implementation of Latex in a Unix environment. We also thank a referee for several, constructive suggestions.     

Money demand, the Cagan model, testing rational expectations vs adaptive expectations: The case of Turkey

This paper estimates the Cagan type demand for money function for Turkish economy during the period 1986:1–1995:3 and tests whether Cagan's specification fits the Turkish data using an econometric technique assuming that forecasting errors are stationary. This paper also tests the hypothesis that monetary policy was implemented in aiming to maximize the inflation tax revenue. Finally, the Cagan model is estimated with the additional assumption of rational expectations for Turkey for the considered period.

An ascending double auction

We show why the failure of the affiliation assumption prevents the double auction from achieving efficient outcomes when values are interdependent. This motivates the study of an ascending price version of the double auction. It is shown that when there is a sufficiently large, but still finite, number of sellers, this mechanism has an approximate perfect Bayesian equilibrium in which traders continue bidding if and only if their true estimates of the ‘value’ of the object being traded exceed the current price. This equilibrium is ex post efficient and has a rational expectations property in the sense that along the equilibrium path traders appear to have made the best possible trades conditional on information revealed by the trading process. We thank two anonymous referees and Dan Kovenock, the Editor, whose detailed comments and suggestions have allowed us to substantially improve the paper. We also thank seminar participants at University of Toronto, University of Wisconsin-Madison, Summer 2003 North American Meetings of the Econometric Society, 2004 NSF Decentralization Conference for their comments.     

Rationalizable expectations and sunspot equilibria in an overlapping-generations economy

There are two theories for the treatment of market uncertainty: rationalizable expectations and sunspot equilibria. This paper shows how the game-theoretic solution concept of rationalizable expectations can be applied to an overlapping-generations exchange economy. Some general properties of these equilibria are discussed. It is shown that rationalizable-expectations equilibria are the predictions yielded by considering sunspot equilibria in which probability beliefs may differ across individuals. This result allows for a new interpretation of sunspot equilibria and helps to understand their relevance.     

Rational expectations for large CGE models: A practical algorithm and a policy application

We describe a simple iterative method for solving large dynamic CGE models under rational expectations. Details are given for Australia's MONASH model but the approach applies to a wide range of CGE models. The method is automated in the RunMONASH Windows software, putting CGE modelling under rational expectations within the reach of non-specialist modellers. We provide an illustrative application in which MONASH results under rational expectations are compared with results under static expectations. The application and supporting software can be downloaded. Results from the application are interpreted in terms of elementary economic mechanisms.     

Economic planning for market economies : The optimality of planning in an economy with uncertainty and asymmetrical information

The paper is based on a disequilibrium model which is Keynesian in the ‘short run’, ie with given expectations, but which admits of a continuum of equilibria when expectations are rational. Expectations are adaptive (so that they are rational only in the long run) but can be influenced by an indicative plan. The government and the private sector have differing information sets, each knowing some things the other sector does not (spontaneously) know. It is shown that in this world, an optimal plan dominates a self-fulfilling plan, which in turn dominates a no-planning equilibrium.     

Expectations in micro data: rationality revisited

An increasing number of longitudinal data sets collect expectations information regarding a variety of future individual level events and decisions, providing researchers with the opportunity to explore expectations over micro variables in detail. We present a theoretical framework and an econometric methodology to use that type of information to test the Rational Expectations (RE) hypothesis in models of individual behavior. This RE assumption at the micro level underlies a majority of the research in applied fields in economics, and it is the common foundation of most work in dynamic models of individual behavior. We present tests of three different types of expectations using two different panel data sets that represent two very different populations. In all three cases we cannot reject the RE hypothesis. Our results support a wide variety of models in economics, and other disciplines, that assume rational behavior. We would like to acknowledge outstanding research assistance from Huan Ni.

Rational inattention and revealed preference: The data-theoretic approach to economic modeling

Beliefs have as pervasive a role as utility functions in economic models of choice, and are no more visible to the naked eye. This suggests the value of a data-theoretic approach to imperfect information along the lines of Samuelson's “revealed preference” approach to utility maximization. I introduce a recently developed approach of this nature (Caplin and Martin, 2013a, Caplin and Dean, 2013a, Caplin and Dean, 2013b). I highlight the broader potential of the data-theoretic approach to answer questions of an inter-disciplinary nature and to discipline an oncoming flood of behaviorally-relevant data.
