Metaphors,semiotics and futures studies

Metaphor belongs to key concepts of semiotics. I have made my career in the field of semiotics and I appreciate the possibility to tell to the scientific community of futurists how a semiotician sees the various functions of metaphors and their connections to the future. The edited volume CLA 2.0 (Inayatullah & Milojevic, 2015) shows that in addition to metaphors, many futures researchers have found the general language-based approach of semiotics. The paper deals with three issues: first the theory of metaphors as such, much discussed in the semiotic literature; then what semiotics says about the future; and finally, what kind of semiotics we are considering here. I would propose to scrutinise the problem of metaphors and future in light of my own new theory which I call ‘existential semiotics’.     

Ethical dilemmas: Teaching futures in schools

Educational policy is implicitly futures oriented, yet in most instances fails to engage learners with explicit futures tools and concepts at a school level. Futures studies in education, or futures education has the potential to reposition learning as purposeful and mobilizes the lives of participants by connecting the curriculum of schools with the multifaceted futures of learners. This is a complex task within the tensions often existing between: the cultural role of a school, the expectations of a society, the expertise of teachers, and the increasingly diverse needs of learners (Bateman, 2012). It is between the tensions of these things that the ‘ethical’ issues of what is taught, or omitted as content in a classroom and the consequences of these choices are evident.This paper highlights ethical and moral dilemmas, as they were apparent in two futures education projects. In the first study, the teachers discuss the inherent limitations of offering a broader and more futures oriented curriculum. In the second study, teachers reflect upon their students’ anxiety with regards to futures images as they are interrogated within a curriculum study. Each of these studies highlights the ethical challenges that arise, when possible, preferable and probable futures are developed as part of learning in school settings, which are culturally and demographically diverse.Tirri and Husu (2002) highlight the ethical dilemmas, which emerge in classrooms around the world, based on conflicts in values and competing intentions between key stakeholders. In the studies which contribute to this discussion, there is evidence to suggest that futures thinking causes conflict within an individual's perception of how the world should be, or their worldview as a result of futures imagining which goes beyond what is taken for granted, or is an assumed future eventuality. In the same way, Carrington, Deppeler, and Moss (2010) argue that all curriculum choices about what is taught (or not taught) in a classroom reflect an ethical decision made by a teacher, with regards to what is foregrounded for learning and what is omitted.It is crucial to re-examine the role of a school in educating students for their futures, as opposed to educating students with an aim of furthering governmental agendas. More significantly, however, as this paper highlights, it is exploring the boundaries of what is acceptable or unacceptable, appropriate or inappropriate to teach in a classroom, given the changing diversities of schools and education systems throughout the world.     

Toward a simulated replica of futures: Classification and possible trajectories of simulation in futures studies

Simulation is likely to become a prominent method of theory development. Futures studies have used simulation in different ways such as evaluating scenarios. Nonetheless, the central attributes of computer simulation such as reductionism-based abstraction, determinism and elimination of stakeholders are the main barriers of successful implementation of simulation in FS. In this paper, we would paint the plausible evolutionary panorama of futures of simulation in futures studies after looking at the role of simulation in FS so far. The possible mechanisms and partnerships required to be applied to grapple the above-mentioned difficulties will be enumerated and investigated. These, in three categories, comprise firstly, human-machine interactions such as quasi-game simulations, and scenario visualization, secondly, large-network simulations including crowd sourcing, and thirdly, simulation platforms for replication of emergence. Ergo, crafting a classification of simulation in futures studies and the possible developments will be the main contribution of this paper. A novel double diamond classification will be presented as well which reflects the past and plausible futures of simulation in futures studies.     

Energy futures: Diversity and the need for assessment

In energy policy and energy research, decisions have to be made about the technologies and infrastructures that may be used to provide and distribute energy in future times, some of which are very distant. Frequently, energy futures such as predictions of the energy demand or energy scenarios are used for decision-support in this field. The diversity of energy futures, however, threatens any possibility for orientation, could lead to disorientation instead of helping more rational decision-making and could be used for ideological purpose. In this paper, we investigate concepts and approaches for scrutinizing, comparing and assessing the various energy futures from an epistemological point of view. Following the analysis of the structure of (energy) futures we will conclude that comparisons and assessments of energy futures should be made through processes of scrutiny and assessment, looking into the ingredients which have been used in constructing the respective futures, and into the process of their composition. Providing much more insight into the cognitive and normative structure of energy futures is required for allowing a more transparent and deliberative societal debate about future energy systems.     

Price limits in futures markets: effects on the price discovery process and volatility

Price limits are actively employed by many futures exchanges as a regulatory mechanism directed at reducing volatility and improving price discovery process. The aim of this paper is to investigate whether price limits achieve these goals without affecting market liquidity for a number of agricultural futures contracts. We employ models of changing volatility in order to show that price limits do not appear to significantly reduce market volatility. In addition, we find evidence confirming the hypothesis that price limits delay price discovery instead of facilitating it. Our results also suggest that the impact of price limits on volatility and price reversals, found in previous studies, are mainly due to the properties inherent to the futures returns, such as volatility clustering. Finally, although trading decreases significantly due to the price limits, traders do not seem to switch from the contracts affected by price limits to other maturities in order to minimize the impact of circuit breakers.     

Narrative futures and the governance of energy transitions

Today's societies confront an enormous challenge with regard to governing complex energy systems change. We argue that futures approaches based on narrative strategies that encourage individual and collective storytelling and meaning construction offer a valuable tool for enhancing societal capacity to meet this and similar governance challenges. We report on a two-day scenario planning exercise that sought to implement and test these ideas. The exercise involved a diverse group of professionals in both energy and non-energy fields, with a question focused on the narrative construction and deliberation of scenarios about Arizona's energy future in 2050.     

Using futures contracts for corporate hedging: The problem of expiry and a possible solution

Companies using futures contracts for hedging purposes need to roll over their contracts if the maturity of their exposure exceeds that of the futures contracts. This entails basis risk that can reduce significantly the effectiveness of the hedge. In this paper an alternative form of futures contract is proposed. the contract never expires and can be used for long-term hedging without the need for rolling-over into a new contract. the contract is shown to be equivalent to a portfolio of conventional futures contracts of differing maturities. Its price is determined by arbitrage against the underlying asset.     

The New Narrative: Applying narratology to the shaping of futures outputs

Both scenario development and design practices incorporate elements of storytelling, but this use remains undertheorised. This paper will draw upon literary theory, film theory and science fiction criticism to develop an analytical model of narrative structure and rhetorics which speaks to the concerns of scenario developers and designers when engaged in shaping the final outputs or deliverables of a futures project.After highlighting the differing role of telos in art and futures and defining the metacategory of “narratives of futurity”, this paper then defines the terms “story”, “narrative”, “narrator” and “world” in the literary context. It then shows how those concepts map onto futures practice, before going into detail regarding the variety of narrative strategies available across a range of different forms and media, and the qualitative effects that they can reproduce in audiences. There follows the construction of a 2 × 2 matrix based on the critical concepts of narrative mode and narrative logic, within which narratives of futurity might be usefully catalogued and compared, and from which certain broad conclusions may be reached as regards the relation between choice of medium and rhetorical effect. The implications of this analysis are explored in detail.     

The evolution of futures in school education

School education seems to be mostly stuck in an outdated industrial era worldview, unable to sufficiently address the significance and increasing rapidity of changes to humanity that are upon us. An integrated forward-looking view should, now more than ever, be of central importance in how we educate. Yet there is little sign that—unlike corporations—school systems are recognising the true value of futures studies. A brief history of futures in school education shows the significant role played by the World Futures Studies Federation in its evolution to date. The article also introduces integral analysis as a way of opening up new possibilities to help school education develop due foresight and to more fully realise its potential as a prime facilitator in individual and cultural evolution.     

Profitability of return and sentiment-based investment strategies in US futures markets

Our study adds to the literature by providing initial evidence on the interaction between short-horizon return predictability and investors’ sentiment by traders’ types on US commodity futures market. We find that the short-term contrarian profit is more associated with an increase rather than a decrease in hedgers’ sentiment. However, the interaction between lagged return and past change in speculators’ sentiment illustrates that the short-term contrarian profit is more associated with a decrease rather than an increase in sentiment. Based on behavioral finance theories, we conclude that hedgers behave like irrational traders while speculators behave like rational ones. Using Chou et al. (2007) decomposition, our results confirm the obtained relations between change in trader's sentiment and the overreaction. By expanding this decomposition, we find that the winners’ portfolio tends to more overreact with futures specific information. Also, the cross-autocorrelation between winners and losers and between losers and winners can represent another source of contrarian profits.     

The impact of Russian sanctions on the return of agricultural commodity futures in the EU

During the last conflict between Russia and the Ukraine in 2014, the EU imposed various multilateral sanctions on Russia. As a response, Russia retaliated these measures by banning the agricultural imports from the EU. This study explores whether the retaliation sanctions taken by Russia were already expected by investors or came as a complete surprise. For this purpose, I compare the impact of sanction-related news before and after the official announcement of these sanctions by president Putin in August 2014 on the weekly return of a number of agricultural commodity futures traded at two European commodity exchanges. A newly created indicator on sanction-related news is used that is based on the number of articles that have been published in the major European newspapers containing information about the import ban. The main findings clearly point out that before the imposition of the boycott it was already partly anticipated. The publication of sanction-related news caused a significant drop in the futures return of a number of banned agricultural commodities in the weeks prior to the formal announcement.     

The role of speculation in international futures markets on commodity prices

The role of futures contracts on spot prices has been one of the key focus areas of research since the recent surge in commodity prices and increase in the volatility of commodity returns. However, no consensus arises from this literature, and hence it is difficult to link the use of futures contracts in agricultural commodities by non-hedgers and the growing food insecurity within developing countries. The purpose of this paper is to highlight causal relationships from futures contracts to spot prices of underlying assets, namely agricultural commodities. As research that focus on exchange-traded funds do not provide any clear conclusions, we focus on the imbalance between short- and long-open positions, this imbalance being caused by the exchange traded funds’ participation in futures markets. In this paper, we estimate relationships between financial variables including indicators for speculation in futures markets and the returns of cocoa, corn, soybean, wheat, coffee, rice, and sugar on a weekly basis from 1998 to 2013. Significant results lead to Granger-causality tests that in turn validate the hypothesis of a positive impact of speculation in futures markets to returns on the underlying commodities.     

Round-the-clock market efficiency and home bias: Evidence from the international Japanese government bonds futures markets

This paper examines how information is processed between almost identical international futures markets: London (LIFFE) and Tokyo (TSE) JGB futures. In these markets, variations in open-to-open changes are virtually the same as those of close-to-close changes, suggesting that information is transmitted efficiently across markets with small opening pricing errors. The overall results confirm market efficiency around the clock, yet the intraday U-shaped patterns in volume/volatility of the London JGB futures suggest home bias in international investments, indicating a less global view of trading than expected. Specifically, at the LIFFE open, London investors rush to rebalance portfolios instead of doing so at the TSE close, which is only one hour before the LIFFE opens.     

The smirk in the S&P500 futures options prices: a linearized factor analysis

In the S&P500 futures options, we identify three factors, corresponding to movements in the underlying, parallel movements, and tilting of the cross section of implied volatilities (the “smirk factor”). We relate these factors non-linearly to movements in the option prices. They seem to be diffusive in nature, have significant associated risk premia, and can account for an overwhelming part of the option price movements. We interpret the options smirk, which is the notion that out-of-the-money (OTM) puts seem expensive relative to OTM calls, in terms of the prices of these risk factors. Going short OTM puts and long OTM calls, corresponding to the third factor, makes a profit on average, but this corresponds to its risk premium, and does not represent a market inefficiency. Our smirk factor is useful for hedging option portfolios, but seems unrelated to movements in the underlying, and does not fit into the framework of the jump-diffusion models.      

American futures options arbitrage: evidence from the Nikkei 225 options market

Previous studies have examined the profitability of European index options arbitrage. This paper adds to the literature by investigating the arbitrage profitability of American index options—the Nikkei 225 index futures options traded on the Singapore Stock Exchange (SGX). Using the real-time bid–ask prices, we find evidence of profitable arbitrage opportunities, while the frequency of observations violating no-arbitrage bounds and the magnitude of arbitrage profits decrease with the level of transaction costs. Our results have implications for the analysis of American options market efficiency. Failure to use bid–ask prices may lead to biased conclusions.     

Policy metaphors: From the tuberculosis crusade to the obesity apocalypse

In this paper we examine the conceptual and political work that metaphors do, with particular regard to how they construct problems and thus in turn limit the range of solutions.¹ Common metaphors in the United States, Canada, the United Kingdom and Australia are examined (war, disease and crime metaphors, and the economy and nation as a body) by analysing historical and modern texts about the policy issues of tuberculosis, immigration, asylum seeking, welfare, obesity and food insecurity. Through this we show that metaphors, in conjunction with discourses, may work to: naturalise and privilege certain constructions of problems; attribute blame and responsibility; support claims about the urgency and extent of required intervention (and who should deliver it, to whom and how); influence the identification and consideration of solutions by constructing the problem in particular ways; intentionally or unintentionally result in stigmatisation and non-trivial discrimination (social and workplace); and erase or highlight the role of actors, processes, social relations and systems. Vallis has developed the analysis, the bulk of the paper, and Inayatullah has articulated the theoretical links to causal layered analaysis (CLA). While there are multiple ways to use CLA, in this paper we use CLA to map a number of issues accross perspectives and frames, and to deconstruct creating the possibility for alternative futures. We do not explore alternative or preferred futures.     

Examining the forward pricing function of the Australian equity index futures contract

The relationship between the Australian equity index futures and spot prices is examined. Tests indicate that futures prices with one, two and three months to maturity are unbiased predictors of the spot and hence provide an efficient hedging mechanism for Australian equity index market participants, while six‐, nine‐ and twelve‐month futures prices are biased predictors of spot prices, indicating that speculative opportunities may exist in futures contracts for these time spreads. An analysis of the short‐run dynamic properties of the long‐run equilibrium relationship found that for all time spreads the futures prices respond to changes in the long‐run equilibrium, and for the twelve‐month contract, both futures and spot prices adjust to return to the long‐run equilibrium.     

Evidence on the arbitrage efficiency of SPI index futures and options markets

This paper is concerned with arbitrage opportunities in the futures and futures option contracts traded on the Sydney Futures Exchange (SFE) within a put-call-futures-parity (PCFP) framework. Tick-by-tick transaction price data are employed so that the futures contracts, the call futures options and the put futures options can be matched within a one-minute interval. This paper also takes into account the realistic transaction costs that an arbitrager has to incur, including the implicit bid-ask spread. A thorough ex post analysis is first carried out. The results reveal a significant number of violations of the PCFP in the sample. Ex ante tests are then conducted whereby ex post profitable arbitrage strategies, signified by the matched trios of futures, put and call contracts, are executed with lags up to 3 min. The ex ante results are similar to the ex post results. However, further analysis reveals that the exploitability of the identified arbitrage opportunities is very limited due to the small trading volumes of the futures and options contracts. Thus, we conclude that there is no strong evidence against the arbitrage efficiency between the SPI index futures and options markets in Australia.      

投资者结构与期限结构对期货市场效率的影响研究

有效市场假设认为,投资者不能通过任何信息的获取而获得超额收益,即价格能够及时地反映所标资产的相关信息和风险。通过对上海期货市场金融危机前后交易数据的检验,发现其存在显著的长期惯性利润,证明了其不符合有效市场假设和可能存在市场操纵行为。Granger因果检验进一步发现短期的投机行为越多惯性利润越低,长期惯性利润越高投机行为越多。因此上海期货市场有必要通过减少交易成本和提供更多的交易信息去改善市场结构和效率。     

The price discovery role of day traders in futures market: Evidence from different types of day traders

Using proprietary account-level transaction data in the futures market where day traders are self-declared ex ante, this study investigates whether day traders enhance price discovery at the market level. From a natural classification of day traders, we find that heterogeneous day traders have differential effects on price discovery. Self-declared day traders, who benefit from low margin requirement, do not improve price discovery measured by information share. In contrast, non-declared traders, who are not self-declared as day traders, improve price discovery. Their positive impacts on price discovery are particularly significant during periods of high volatility and arrival of new information. Overall, a margin stimulating policy may encourage more day trading, but may also attract overconfident investors, especially inexperienced ones, and who do not enhance price discovery.
