Prospect theory,mitigation and adaptation to climate change

Prospect theory (PT) is a widely accepted theory for decisions under uncertainty. However, so far a systematic application to climate policy (CP) does not exist. One important postulation of PT is that outcomes are perceived as gains or losses, relative to the reference point. When it comes to CP, different decision-makers may have different reference points. For example, one decision-maker perceives the current climate as the reference point whereas another decision-maker may have another one, say climate in 100 years. For the former, climate damages are losses and the benefits of CP are reductions of losses. For the latter, benefits of CP are gains. PT suggests that the former places a higher value in CP than the latter. After a critical review whether and how PT may be applied to CP, the paper systematically presents this and other cases where PT offers new insights into climate-related analyses, notwithstanding the importance of well-known aspects such as discounting, altruism, political and economic costs. It is shown that accounting for PT may contribute to a better understanding of some well-known puzzles in the climate debate, including different preferences for CP amongst individuals and nations, the role of technical vs. financial adaptation, and the apparent preference for hard protection measures in coastal adaptation. Finally, concrete possibilities for empirical research on these effects are proposed.     

Prospect theory and trading patterns

Reference dependence, loss aversion, and risk seeking for losses together comprise the preference-based component of prospect theory that sets its value function apart from the standard risk-aversion model. Using an elasticity analysis, we show that this distinctive preference component serves to underpin negative-feedback trading propensities, but cannot manifest itself in behavior directly or holistically at the individual-choice level. We then propose and demonstrate that the market interaction between prospect-theory investors and regular CRRA investors allows this preference component to dominate in equilibrium behavior and hence helps to reestablish the intuitive link between prospect-theory preferences and negative-feedback trading patterns. In the model, the interaction also reconciles the contrarian behavior of prospect-theory investors with asymmetric volatility and short-term return reversal. The results suggest that prospect-theory preferences can lead investors to behave endogenously as contrarian noise traders in the market interaction process.     

A theory of the corporate decision to resist FASB standards: An organization theory perspective

This paper develops a theoretical framework that specifies the conditions under which corporations are likely to resist financial reporting standards proposed by the Financial Accounting Standards Board (FASB). Determinants of corporate resistance to FASB standards are identified at three levels of analysis: the standard, the corporation, and the corporation’s industry. Propositions are formulated summarizing the effects of the determinants at these three levels, and guidelines are suggested for testing the propositions. Implications for the theory and the practice of accounting regulation are also discussed. The overall goal of the paper is to enhance our understanding of the drivers of corporate resistance to FASB standards, so that accounting regulators can manage the implementation of accounting standards more effectively.     

Prospect theory and the effectiveness of price limits

Assuming that traders are risk-neutral, Brennan (1986) shows that price limits are effective in improving the efficiency of futures contracts with limited accessibility to information because they obscure the exact loss when they are triggered. However, Brennan's (1986) model fails to explain why price limits also exist in contracts with abundant information like those of financial futures. We show that when traders are loss-averse, the effectiveness of price limits is strengthened even in the presence of precise information. Thus, our analysis provides a theoretical foundation explaining why price limits can be useful when market participants are not fully rational.     

Prospect theory,mental accounting,and momentum

The tendency of some investors to hold on to their losing stocks, driven by prospect theory and mental accounting, creates a spread between a stock's fundamental value and its equilibrium price, as well as price underreaction to information. Spread convergence, arising from the random evolution of fundamental values and the updating of reference prices, generates predictable equilibrium prices interpretable as possessing momentum. Empirically, a variable proxying for aggregate unrealized capital gains appears to be the key variable that generates the profitability of a momentum strategy. Controlling for this variable, past returns have no predictability for the cross-section of returns.     

Pricing and hedging basket options to prespecified levels of acceptability

The concept of stress levels embedded in S&P500 options is defined and illustrated with explicit constructions. The particular example of a stress function used is MINMAXVAR. Seven joint laws for the top 50 stocks in the index are considered. The first time changes a Gaussian one factor copula. The remaining six employ correlated Brownian motion independently time changed in each coordinate. Four models use daily returns, either run as Lévy processes or scaled to the option maturity. The last two employ risk-neutral marginals from the VGSSD and CGMYSSD Sato processes. The smallest stress function uses CGMYSSD risk-neutral marginals and Lévy correlation. Running the Lévy process yields a lower stress surface than scaling to the option maturity. Static hedging of basket options to a particular level of acceptability is shown to substantially lower the price at which the basket option may be offered.     

Prospect theory,the disposition effect,and asset prices

We build a general equilibrium model to examine the implications of prospect theory for the disposition effect, asset prices, and trading volume. Diminishing sensitivity predicts a disposition effect, price momentum, a reduced return volatility, and a positive return-volume correlation. Loss aversion generally predicts the opposite. In calibrated economies, there is a nontrivial range of preference parameters for prospect theory to simultaneously explain the disposition effect, the momentum effect, and the equity premium puzzle. Our model is helpful for understanding a wide range of financial phenomena and it also suggests new testable predictions.     

Prospect theory and the risk-return paradox: some recent evidence

There is extensive evidence indicating a negative risk–return relation when a firm’s performance is measured based on accounting measures such as return on asset (ROA) and return on equity (ROE). Previous studies show that the risk-return paradox can be explained by the prospect theory, which predicts that managers’ risk attitudes are different for firms of different performances. However, those studies mostly use earlier data from the COMPUSTAT database, which suffers from a survivorship bias. Failure to account for delisting firms may understate the risk–return relation. We reexamine the mixture of risk-seeking and risk-averse behaviors based on an updated 20-year sample period that is free from the survivorship problem. Interestingly, our results show stronger and robust evidence supporting the prospect theory during the period from 1984 to 2003.     

Nine ways for a decision maker to use theoretical notions,with special reference to teaching agency theory for management accounting

Management accounting curricula can be made more practical by including additional coverage of theory. When considering both theory and application as parts of management accounting curricula we ought, however, to give attention to the dissimilar ways in which the two are connected. In this note, nine ways in which a decision-maker might use theory are discerned. Each of these nine ways of applying theory is illustrated with examples from agency theory. As management accounting is concerned with providing information for decision making, the nine ways to apply theory should be incorporated in management accounting curricula. A teaching tool is presented using agency theory as an example.     

The profitability of interest arbitrage when the base currency is pegged to a basket

When the interest rate on a currency that is pegged to a basket differs from the interest rate on the basket (as a weighted average), it is possible to make profit from interest arbitrage by going short on the basket and long on the pegged currency, or vice versa. This proposition is illustrated by using data on the Kuwaiti dinar and its basket currencies over the period 1998–2002 when the currency was pegged to a basket. Monte Carlo simulations show that the probability of making arbitrage profit from any single operation is about 95%.     

Applying a factor copula to value basket credit linked notes with issuer default risk

This paper explores a reasonable coupon rate for basket credit linked notes (BCLN) with issuer default risk. Based on the one factor Gaussian copula model, this paper proposes three methods of incorporating issuer default into BCLN pricing. Numerical results indicate that issuer default risk impacts BCLN coupon rate. Furthermore, coupon rate differs with changes in correlation structure among the three methods. One of the three methods is ultimately identified as the most suitable.     

Buying a house and the decision to use a real estate broker

This study examines the factors that affect the decision by home buyers to use real estate brokers and the subsequent effect this decision has on home prices. Buyers with high opportunity costs and the least amount of information about local market conditions are the most likely to use brokers; a finding consistent with the role of the real estate broker as a market intermediary. Not surprisingly, these were some of the same factors that also have a positive impact on selling price. An important finding of this study is that when selection bias is adequately controlled, the real estate broker has no appreciable, independent impact on selling price. This, in turn, suggests a nonsegmented, highly competitive housing market.     

Supporting ALARP decision making by cost benefit analysis and multiattribute utility theory

Current guidance in the UK and elsewhere indicate upper and target risk limits for the operation of nuclear plant in terms of individual risk per annum. ‘As low as reasonably practicable’ (ALARP) arguments are used to justify the acceptance or rejection of policies that lead to risk changes between these limits. The suitability of cost‐benefit analysis (CBA) and multiattribute utility theory (MAUT) are assessed for performing ALARP (‘as low as reasonably possible’) assessments, in particular within the nuclear industry. Four problems stand out in current CBA applications to ALARP, concerning the determination of prices of safety gains or detriments, the valuation of group and individual risk, calculations using ‘disproportionality’, and the use of discounting to trade‐off risks through time. This last point has received less attention in the past but is important because of the growing interest in risk‐informed regulation in which policies extend over several timeframes and distribute the risk unevenly over these, or in policies that lead to a nonuniform risk within a single timeframe (such as maintenance policies). The problems associated with giving quantitative support to such decisions are discussed. It is argued that multiattribute utility methods (MAUT) provide an alternative methodology to CBA which enable the four problems described above to be addressed in a more satisfactory way. Through sensitivity analysis MAUT can address the perceptions of all stakeholder groups, facilitating constructive discussion and elucidating the key points of disagreement. It is also argued that by being explicitly subjective it provides an open, auditable and clear analysis in contrast to the illusory objectivity of CBA. CBA seeks to justify a decision by using a common basis for weights (prices), while MAUT recognizes that different parties may want to give different valuations. It then allows the analyst to explore the ways in which different parties might (or might not) come to the same conclusion even when weighting items differently.     

First‐price auctions with resale and with outcomes robust to bid disclosure

Although there exists a pure separating equilibrium of the two‐bidder first‐price auction with resale when the bids are kept secret, the ratchet effect prevents the existence of such an equilibrium if the bidders are heterogeneous and the bids are fully disclosed. Nevertheless, we construct a behavioral equilibrium under full disclosure that is equivalent to the pure separating equilibrium under no disclosure. Thus, if the bidders follow this equilibrium, the choice of the disclosure regime does not affect the final allocation of the item nor the expected payoffs.     

Estimation of the bid - ask spread and its components: a new approach

We show that time variation in expected returns and/or partialprice adjustments lead to a downward bias in previous estimatorsof both the spread and its components. We introduce a new approachthat provides unbiased and efficient estimators of the componentsof the spread. We find that between 77 and 97 percent of thedownward bias in previous spread estimate is caused by timevariation in expected returns. More importantly, the adverse-selectioncomponent, though significant, accounts for a much smaller proportion(8 to 13 percent) of the quoted spread, at least for small trades,than the proportion (over 40 percent) previously reported inthe literature. Order processing costs are the predominant componentof quoted spreads.     

Technological advances and the decision to invest

Technological advances impact a firm’s investment decision, as they affect the investment cost. They can also affect the profitability due to demand shocks. We study a firm’s optimal investment decision when technological advances occur as surprises and induce uncertain reductions in the investment cost and in earnings. Despite this complex setting we derive closed-form solutions for the investment option value and the investment threshold. When technological advances only impact the investment cost, we demonstrate significant contributions compared to existing research, which restricts the analysis by keeping the expected investment cost path constant. For example, we show that, albeit the investment threshold is constant, the option value is very sensitive in the expected impact of technological advances. Leaving the restrictive setting, we obtain more intuitive results, e.g. that more frequent technological advances increase the option value. When technological advances impact future earnings we find important long-term effects: the investment threshold increases, whereas the option value decreases. Finally, earnings volatility postpones investment, while uncertainty due to technological advances expedites investment.

The industry effect and the decision to integrate vertically in a crisis context

ABSTRACT

The objective of this work is twofold: firstly, to study if the characteristics of the industry affect certain financial and strategic decisions of manufacturing firms and, secondly, to determine if the strategy of diversifying the activity through vertical integration generates good financial results in times of crisis, depending on the industry. To this end, an analysis is carried out with panel data from 9,523 firms in the period between 2008 and 2013. The results show that there are different strategies that firms must follow, depending on the industry to which they belong. In sectors with lower operational risk, those firms characterized by greater specificity and better product quality obtained higher profitability. However, in riskier sectors, firms with more specific assets assumed too many risks and in times of crisis have seen their profitability fall. Likewise, it is observed that the decision to integrate vertically has mitigated the weak points of each sector, allowing firms to better weather the economic–financial crisis in which this research is framed.     

The effect of information load on decision makers' cue utilization levels and decision quality in a financial distress decision task

Seventeen practising auditors and sixty-seven accounting students participated in a decision making experiment that examined the effect of increasing amounts of accounting information on cue usage and decision quality. Each participant made financial distress decisions under three levels of information load. Approximately one-third of those participating apparently experienced information overload and exhibited an inverted-U relationship between information usage and information load; the others exhibited patterns of increasing cue usage. The individuals who apparently experienced information overload also reached decisions of lesser quality, as indicated by significantly lower decision making consistency, lesser agreement with a composite judge, and lower consensus.     

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.
