Assessing the validity of the Delphi technique

Forecasting is an essential factor in policy formulation and planning. It helps determine the direction of future actions. While a number of forecasting techniques are utilized to forecast the future, it is important to know just how valid those forecasting techniques can be. The Delphi technique has been called the ‘cornerstone of futures research’. This study reports the results of the assessment of the accuracy of the forecasts derived from the Delphi technique. Twenty-five experts in the communication field assessed 24 trends and 17 events in the state of Hawaii as of 1991. The expert assessments were then compared with the forecasts made by utilizing the Delphi technique 16 years earlier. The results showed that the trend forecasts were significantly correlated with the trend assessment. They also showed that the Delphi technique had accurately forecast approximately half the events that could be evaluated as of 1991. Results from this study lend support to the use of the Delphi technique in long-range forecasting and reveal some interesting findings in forecasting the developments in communication in Hawaii.

Futures and forward price differential and the effect of marking‐to‐market: Australian evidence

The objective of this paper is to examine the effects of marking‐to‐market of futures contracts on the price differential between futures and forward contracts based on the predictions of the Cox, Ingersoll and Ross (1981) (CIR) model. Cox et al ., (1981) derive a series of propositions with respect to the relationship between futures and forward prices and a set of testable implications. These are tested empirically in this paper using Australian data from November 1991 to June 1997. The results provide evidence of the presence of significant futures and forward price differences, where the futures price is consistently below the forward price. Only partial support is found for the Cox et al ., (1981) propositions, implying that the effect of marking‐to‐market is not able to fully account for the price differential. Therefore, it is not possible to rule out the influence of other institutional factors on the futures‐forward price difference.

Futures and realized cash or settle prices for gold,silver, and copper

This article examines the relation between 15-, 30-, 45-, and 60-day gold, silver, and copper futures, and their realized cash or delivery settle prices, for deliveries on the first, middle, and last business day (FD, MD, and LD, respectively) of the delivery month. Samples of futures prices for gold, silver, and copper, and the realized cash or delivery settle prices, based on fixed maturities for a cross-section of contracts are used, because time-series over fixed maturities are unfeasible owing to the restrictive maturity periods in these contracts. This study contrasts with similar studies for forwards, which are not hampered by this problem (e.g., Baillie and Bollerslev in 1989), studies that use contemporaneous time-series of futures and cash prices to obtain optimal hedge ratios (e.g., Ghosh and Clayton in 1996), and studies that examine for parity between different futures prices (e.g., Franses and Kofman in 1991). Near-term gold, closest to delivery silver and all copper futures (the latter only with settle prices at delivery) are good predictors of the future cash price, except for silver and copper deliveries on the last day of delivery months. These results are consistent with previous studies on short-term cash (Ma in 1985) and futures (Ma and Soenen in 1988) parity between gold and silver, and with Gross's (1988) results for copper. The longer-term gold (45- and 60-day) and silver (30-, 45-, and 60-day) futures reject an unbiased expectations hypothesis. This result is consistent with Leistikow (1990) because cash prices respond less than futures prices in these instances.     

Volatility,information, and double versus walrasian auction pricing in US and Japanese futures markets

This study empirically examines volatility in US and Japanese commodity futures markets. The US futures market, COMEX, is double auction with continuous trading, whereas the Japanese futures market, TOCOM, was Walrasian with discrete trading until April 1991. We find intraday volatility for gold futures contracts to be significantly higher on COMEX than TOCOM throughout the sample period and is attributable to differences in information flows and market micro-structures. Evidence is also provided that exchange volume conveys information both within and across markets, which is consistent with the French and Roll, 1986 (French, K.R., Roll, R., 1986. Stock return variances: The arrival of information and the reaction of traders. Journal of Financial Economics 17, 5–26) private-information based rational trading model. Finally, daily variance and autocorrelation estimates within COMEX are consistent with the extant literature on equity markets.     

A note on execution costs for stock index futures: Information versus liquidity effects

This paper examines execution costs and the impact of trade size for stock index futures using price-volume transaction data from the London International Financial Futures and Options Exchange. Consistent with Subrahmanyam [Rev. Financ. Stud. 4 (1991) 17] we find that effective half spreads in the stock index futures market are small compared to stock markets, and that trades in stock index futures have only a small permanent price impact. This result is important as it helps to better understand the success of equity index products such as index futures and Exchange Traded Funds. We also find that there is no asymmetry in the post-trade price reaction between purchases and sales for stock index futures across various trade sizes. This result is consistent with the conjecture in Chan and Lakonishok [J. Financ. Econ. 33 (1993) 173] that the asymmetry surrounding block trades in stock markets is due to the high cost of short selling and the general reluctance of traders to short sell on stock markets.     

An assessment of futures studies worldwide

This article is based on a recent survey of the futures field. For a report of the survey, see Futures Studies : An International Survey by John McHale and Magda Cordell McHale. The full report on the survey was published by UNITAR, December 1975 and may be purchased from UN Sales Section, Room LX 2300, New York, NY 10017, USA or from Palais de Nations, 1211 Geneva 10, Switzerland. The expansion of the subject is shown by the growing number of conferences, publications, secretariats and commissions, and the subject is characterised by a drive for professional recognition and higher standards of methodological rigour. Changes in futures studies include: the shift from linear forecasting towards more normative modes that consider a range of alternative futures; and a new predominance of social science over physical science among practitioners. Whereas futures studies used to have the appearance of a disciplinary enclave it now appears increasingly like a social movement, attracting a degree of involvement similar to that of the civil rights movement, ecology, or consumerism.     

The WFSF and I

This essay gives an account of my voyage through space and time with the World Futures Studies Federation, and other futures groups, from 1966 to August 1993, although I remain a member of and active in the WFSF. The essay is written mainly from memory with only occasional reference to notes and records and so it may be wrong in some details. My journey was not made alone, but in the company of a very great many people not only in Hawaii but also very literally all over the world. I have not been able to mention everyone one. But my journey continues to this very moment.     

Revisiting a futures studies project—‘Reflections on 1985’

In 1962, a futures studies group was launched in France on behalf of the Commissariat au Plan, reporting directly to the French Prime Minister. The group aimed at ‘studying, on the basis of future-shaping elements, what should be known right now about 1985 France’. This paper revisits that important and original futures studies project, which encapsulated efficiently the dominant values and beliefs of a Western country at a turning point of its political and economical history.In its first part, this note recalls the French context in 1964, the frame of mind, and methodology of the group. Then the main findings of the Group 1985 are outlined, be it evolutions that inspired hope (a wealthier economy, improved living conditions), and also fears attached to the future (individual may face new dependencies and higher pressures, while some shortages could appear), which should be averted thanks to active policies in the fields of education, European unity, scientific research, or public administration reform. Last, this paper analyses both the strengths and weaknesses of the Group 1985 report, drawing lessons that remain valuable for contemporary studies on the future of a whole country.In 1962, Pierre Massé, then Commissaire au Plan, set up a futures study Group chaired by Pierre Guillaumat. The Group published in 1964 a report entitled ‘Reflections on 1985’ which was a stimulating futures studies work. ALEPH thought fruitful to revisit this document.     

Pricing the risks of default

This paper decomposes default risk into timing and recovery risks. The two default components are explicitly priced as if they were traded in the futures market. We develop estimation strategies evaluating recovery risks and then construct implicit prices of contingent securities reflecting purely the timing risk. The models are estimated on monthly data for rates on certificates of deposit offered by institutions in the Savings and Loan Industry, during the 1987–1991 period. Empirical results support market expectations of lower likelihoods of default after 1989.     

Forward and Futures Prices: Evidence from the Foreign Exchange Markets

Cornell and Reinganum (1981) , hereafter CR, report that price differentials for future contracts and forward contracts are statistically insignificant in foreign exchange markets. Based on this finding, CR conclude that marking-to-market is insignificant in the formulation of currency futures prices. This note identifies two potential concerns with the CR tests. One problem relates to the timing of delivery dates for “matched” contracts. A second problem relates to the time period for the CR study. We show that correcting for these problems does not affect the overall conclusions of the CR study; marking-to-market does not appear to have a significant effect on currency futures prices.     

Commodities and Macroeconomic Factors: Unconditional Volatility Measures

Abstract:

This study focuses on the measurement of spillover effects from macroeconomic factors to commodity volatility. It argues that such measurement is sensitive to volatility computation and to causality testing. To this end, I analyze two commodity data sets-gold and the Continuous Commodity Index (1969-2011), and twenty-four Dow Jones futures indexes (1991-2011)-and various macroeconomic indicators. I conclude that the macroeconomic factors that influence volatility generally depend on the commodity under consideration. I also explore whether commodities of the same class experience volatility shifts around the same dates, and find that this is not the case except for energy commodities.     

Jumps and stochastic volatility: exchange rate processes implicit in deutsche mark options

An efficient method is developed for pricing American optionson stochastic volatility/jump-diffusion processes under systematicjump and volatility risk. The parameters implicit in deutschemark (DM) options of the model and various submodels are estimatedover the period 1984 to 1991 via nonlinear generalized leastsquares, and are tested for consistency with $/DM futures pricesand the implicit volatility sample path. The stochastic volatilitysubmodel cannot explain the 'volatility smile' evidence of implicitexcess kurtosis, except under parameters implausible given thetime series properties of implicit volatilities. Jump fearscan explain the smile, and are consistent with one 8 percentDM appreciation 'outlier' observed over the period 1984 to 1991.     

UK Stock Returns and the Impact of Domestic Monetary Policy Shocks

Abstract:  We investigate the influence of changes in UK monetary policy on UK stock returns and the possible reasons behind such a response. Firstly, we conduct an event study to assess the impact of unexpected changes in monetary policy on aggregate and sectoral stock returns. The decomposition of unexpected changes in the policy rate is based on futures markets data. Secondly, using a variance decomposition in the spirit of Campbell (1991) we attempt to identity the channels behind the response of stock returns to monetary policy surprises. The variance decomposition results indicate that the monetary policy shock leads to a persistent negative response in terms of future excess returns for a number of sectors.     

Futures Options and the Volatility of Futures Prices

Assuming nonstochastic interest rates, European futures options are shown to be European options written on a particular asset referred to as a futures bond. Consequently, standard option pricing results may be invoked and standard option pricing techniques may be employed in the case of European futures options. Additional arbitrage restrictions on American futures options are derived. The efficiency of a number of futures option markets is examined. Assuming that at-the-money American futures options are priced accurately by Black's European futures option pricing model, the relationship between market participants' ex ante assessment of futures price volatility and the term to maturity of the underlying futures contract is also investigated empirically.     

Modelling gold futures: should the level of speculation inform our choice of variables?

Prior literature provides conflicting evidence about the impact of speculation on gold futures returns, volatility, and the relationship between market fundamentals and prices. In this paper, we exploit trade volume information to determine the most appropriate family of factors to adopt when modelling gold futures. Using the Disaggregated Commitment of Traders report, we find that extreme levels of speculation are informative in that they signify a shift in the relative modelling accuracy of macroeconomic and latent factors. A simple composite prediction framework, incorporating the changing level of speculation, empirically demonstrates the uncovered phenomenon and offers improved predictive accuracy for gold futures prices. Furthermore, our findings are shown to be robust to alternative latent and macroeconomic model specifications.     

Individual approaches to futures thinking and decision making

This paper presents results of a second international web-based survey designed to gather data about how individuals approach thinking about their futures and making decisions regarding their futures. Five hundred and five respondents from 38 countries participated in the survey. Similar to the first survey, the sample has gender, age and religious diversity but is not representative with respect to education, income and race/ethnicity. The results suggest that the external environment provides a great deal of stimuli for people to think about the future (e.g., special occasions like New Years day, birthdays, and funerals). Individuals tend to think about the future more in the morning, and just before bed. Overall, most respondents experience happiness, confidence, and lightness when thinking about the future. Respondents employ many different approaches to thinking about the future, such as relying on personal past experiences, imagining future situations, and relying on their personal intuitions. Most respondents do not pattern their futures decision making on decisions made by others or on tradition. Most respondents believe that their thinking about the future is very worthwhile; most develop plans and take decisive action as a result of their efforts. About three quarters of the respondents report that they are able to predict their personal futures at least one-half of the time. Most respondents face few barriers to thinking about the future, although many reported it would be nice to have more energy, be able to concentrate better, and be able to better organize their thoughts. Females report that thinking about the future is a more emotional experience than it is for males. Males, on the other hand, have more confidence in their futures-oriented decision making abilities. Age plays a big part in how individuals relate to and think about the future. Younger respondents think more about the future more times during the day and find thinking about the future more fearful and anxious. They also pattern their decisions more on those made by others and older individuals. Older respondents tend to rely a great deal upon their lifetime of experiences and worry less about the future. Middle-aged respondents report worrying more about financial and career issues and report that thinking about the future can be emotionally draining.     

Forecasting and planning in the USSR: Part I: 1976–1980

This article considers the development of Soviet Social forecasting in the 1976–1980 period, and begins an updating of Dr Bestuzhev-Lada's report on futures research in the USSR, published in the April 1976 issue of Futures. Particularly significant is the development in the methodological bases of Soviet forecasting activities.
