Meade N, Driver C, 2023, Differing behaviours of forecasters of UK GDP growth, International Journal of Forecasting, Vol: 39, Pages: 772-790, ISSN: 0169-2070
The literature suggests that the dispersion of agents’ forecasts of an event flows from heterogeneity of beliefs and models. Using a data set of fixed event point forecasts of UK GDP growth by a panel of independent forecasters published by HM Treasury, we investigate three questions concerning this dispersion: (a) Are agent's beliefs randomly distributed or do agents fall into groups with similar beliefs? (b) as agents revise their forecasts, what roles are played by their previous and consensus forecasts? and (c) is an agent's private information of persistent value? We find that agents fall into four clusters, a large majority, a few pessimists, and two idiosyncratic agents. Our proposed model of forecast revisions shows agents are influenced positively by a change in the consensus forecast and negatively influenced by the previous distance of their forecast from the consensus. We show that the forecasts of a minority of agents significantly lead the consensus.

The transportation sector is responsible for nearly a quarter of greenhouse gases emissions (GHG); thus, incisive policies are necessary to mitigate the sector’s effect on climate change. Promoting alternative fuel vehicles (AFV) is an essential strategy to reduce GHG emissions in the short term. Here, we study the effects of governmental incentives on the diffusion of ethanol and flex-fuel vehicle technologies in Brazil. We use a multi-generation diffusion model which assumes that new technologies introduce fresh market potential for adopters as well as upgraders from established technologies. Our analysis indicates that tax rates affected the adoption of both gasoline and ethanol technology, but for flex vehicles, the effect of taxation is not significant. The effect of fuel price shocks during the 1990s meant that the introduction of ethanol technology made no significant impact on market potential and a negative word-of-mouth effect contributed to the technology’s failure. In contrast, the introduction of flex technology led to almost a doubling of total market potential. As policy suggestions, we emphasise the importance of tax reduction in addition to promoting versatile technologies, which insulate consumers against price fluctuations.

Adcock CJ, Meade N, 2016, Using parametric classification trees for model selection with applications to financial risk management, European Journal of Operational Research, Vol: 259, Pages: 746-765, ISSN: 0377-2217
We describe two parametric classification tree methods, which allow formal selection of a member of aclass of generalised distributions. In the paper we consider generalised Beta distributions for non-negativerandom variables and the generalised skew-Student distribution for random variables distributed on thereal line. We introduce a class of symmetric generalised multivariate Student distributions, membersof which may also be selected using the classification trees. We present two versions of the parametricclassification tree: specific to general and general to specific. We apply the classification methods todaily returns on stocks from a selection of 15 major, mid-cap and emerging markets. The results showthat the majority of return distributions follow Student’s t, but that a non-negligible minority follow asymmetric generalised Student distribution. We confirm a well-known stylised fact about skewness: ittends not to be persistent. By contrast, kurtosis is persistent. Using the symmetric generalised multivariateStudent distribution, we present a risk management study based on efficient portfolios constructedfrom UKFTSE250 stocks and specifically concerned with the computation of value at risk. The case studydemonstrates that the model selection procedures based on the classification trees lead to more accuratecomputation of VaR than those based on the normal distribution or on non-parametric approaches. Thestudy also shows that the normal distribution may be used for VaR computations for larger portfolioswhen the holding period is longer.

Meade N, 2010, Oil prices – Brownian motion or mean reversion? A study using a one year ahead density forecast criterion, Energy Economics
For oil related investment appraisal, an accurate description of the evolving uncertainty in the oil price is essential. For example, when using real option theory to value an investment, a density function for the future price of oil is central to the option valuation. The literature on oil pricing offers two views. The arbitrage pricing theory literature for oil suggests geometric Brownian motion and mean reversion models. Empirically driven literature suggests ARMA-GARCH models. A characteristic of the price of oil is its sensitivity to shocks thus the density function of future prices must be able to incorporate the uncertainty due to shocks as well as the underlying volatility of a stable market.In this study, the accuracy of density forecasts for up to a year ahead is the major criterion for a comparison of a range of models of oil price behaviour, both those proposed in the literature and following from data analysis. The Kullbach Leibler information criterion is used to measure the accuracy of density forecasts.Using two crude oil price series, Brent and West Texas Intermediate (WTI) representing the US market, we demonstrate that accurate density forecasts are achievable for up to nearly two years ahead using a mixture of two Gaussians innovation process with GARCH and no mean reversion.

This work is concerned with methods for forecasting the filing of patents and was earned out in conjunction with the European Patent Office. The filings data were subdivided by:. Blocs-European Patent Convention countries, Japan, US and the Rest of the World. Industries-main Fields of Technology according to headings A-H of the International Patent Classification (WIPO 2000). The issues addressed are: the benefits of multivariate models versus univariate ones in exploiting any correlations between the filings in different blocs or industries; the effect of aggregation over time (from monthly to annual data) and the effect of aggregation by bloc or by industry on the accuracy of the forecast of total EPO filings. Two approaches are used: the ARIMA framework and the dynamic linear model (DLM) in both univariate and multivariate modes. The main results are: monthly data does tend to provide greater accuracy in annual forecasts; there are no significant benefits to be gained by multivariate modelling and no significant benefits are found from aggregating over blocs or industries. There are benefits from using monthly data, rather than annual data. The best modelling approaches are, for monthly data, the univariate dynamic linear model; for annual data either the univariate ARIMA or DLM could be used. The recommended forecast-ing approach provides a benchmark against which other forecasts drawing on different data sources can be compared. The filing of an application for a patent is the first step in achieving protection for intellectual property. The three major patent offices are the European (EPO), the Japanese (JPO) and the US (USPTO) offices. The examination of each application is a labour intensive process, involving technological and legal expertise. The motivation for this study of the forecasting of patent filings with the EPO is that the forecasts are a prerequisite for manpower planning at an aggregate scale and at the level of availability of expertise in dif
