Overconfidence in investment decisions: An experimental approach

Abstract

By experimentally inducing risk aversion, overconfidence in an investment setting is investigated, comparing the evaluation of actual investment decisions with alternative choices. After selecting their own investment, subjects confront three alternative investment choices, including the optimal one, and are asked about their willingness to pay and to substitute their own for alternative choices. Overconfidence is defined as the persistent overevaluation of the own investment decision. Results indicate that overconfidence increases (i) with the absolute deviation from optimal choices, (ii) with task complexity involving the number of risky assets, and (iii) decreases with individual perceived uncertainty.     

Risk choice and emotional experience: a multi-level comparison between active and passive decision-making

Abstract

Previous studies have consistently indicated the important role of emotional experience in decision-making. While both active and passive decision-making coexist in our daily lives, whether and how active and passive decision-making induce different emotional experience remains unclear. In the present research we conduct three studies to examine differences in emotional experience associated with active and passive decisions at multiple levels. First, at the individual level, using both active and passive modes of the Balloon Analog Risk Task in a laboratory behavior study, we demonstrate that active decision-making is associated with more positive emotional experience compared to passive decision-making, including more happiness, less distress, a greater sense of control, and a stronger sense of achievement. Second, at the neural level, we use functional magnetic resonance imaging and find greater activation in the brain’s emotional circuits during active decisions compared to passive decisions, regardless of the decision outcomes. Finally, at the population level, we conduct a large-scale survey to capture the perception of emotional experience during real-world active and passive decisions, and our results confirm that active decisions engender a greater sense of achievement and sense of control and people prefer active decisions to passive decisions. These findings provide valuable insights into the role of emotion experience in decision-making research and practices.     

Cattle farmers’ perceptions of risk and risk management strategies: evidence from Northern Ethiopia

This study analyzes cattle farmers’ perceptions of risk and risk management strategies in Tigray, Northern Ethiopia. We use survey data from a sample of 356 farmers based on multistage random sampling. Factor analysis is employed to classify scores of risk and management strategies, and multiple regression is then used to investigate the relationship between scores and farmers’ characteristics. The results demonstrate that shortage of family labor, high price of fodder, and limited farm income were perceived as the most important risks. Use of veterinary services, parasite control, and loan utilization were perceived as the most important strategies for managing risks. Livestock disease and labor shortage were perceived as less of a risk by farmers who adopted the practice of zero grazing compared to other farmers, pointing to the potential of this practice for risk reduction. We find strong evidence that farmers engage in multiple risk management practices in order to reduce losses from cattle morbidity and mortality. The results suggest that government strategies that aim at reducing farmers’ risk need to be tailored to specific farm and farmer characteristics. Findings from this study have potentially important policy implications for risk management strategies in developing countries.     

Transparency in the food aisle: the influence of procedural justice on views about labeling GM foods

Issues of transparency lay at the center of the debate surrounding the labeling of genetically modified (GM) food products in the USA. These issues include not only the argument that consumers should be allowed to make purchasing choices based on full disclosure of product ingredients but also that they should have access to the process that makes decisions about labeling. This study examines the influence of procedural justice on perceived decision legitimacy and decision support regarding GM food labeling decisions. Using a 2 × 2 factorial design, participants recruited from an online Qualtrics panel (N = 450) were randomly assigned to read a fictitious news article about an agricultural company’s decision about whether to label their food products as having GM ingredients. Articles varied by the company’s labeling decision (label versus no label) and whether the company listened to public input prior to making the decision (public input versus no public input). The results showed significant main effects on decision support and perceived legitimacy for articles that mentioned public input. Specifically, when participants read articles stating that the company made its decision after listening to public input, they were more supportive of the decision and perceived the decision as more legitimate. Moreover, this main effect occurred irrespective of whether or not the company’s decision was to label GM foods. Our results confirm the influence of procedural justice perceptions in fostering support and perceived legitimacy for controversial risk-related decisions.     

Torts, expertise, and authority: liability of physicians and managed care organizations

We examine optimal individual and entity-level liability for negligence when expected accident costs depend on both the agent's level of expertise and the principal's level of authority. We consider these issues in the context of physician and managed care organization (MCO) liability for medical malpractice. Under current law, physicians generally are considered independent contractors and hence MCOs are not liable for negligent acts by physicians. We find that the practice of reviewing the medical decisions of physicians affects their incentives to take care, which in turn implies that it is efficient for MCOs to be held liable for the torts committed by their physicians.     

Perceived risk and personality traits explaining heterogeneity in Dutch dairy farmers’ beliefs about vaccination against Bluetongue

When designing effective voluntary vaccination strategies against animal disease epidemics, policy-makers need to take into account that different groups of farmers base their participation decisions on different considerations. Using the past Bluetongue virus serotype 8 epidemic of 2006–2009 in Europe as an example, this paper uses the Reasoned Action Approach to identify a set of attitudinal beliefs being the major drivers behind the intended decision to participate in voluntary vaccination. The results show that there is heterogeneity among farmers in these beliefs. In particular, perceived risk, which was captured by a risk attitude and a risk perception of the farmer, and personality traits are associated with variability in beliefs about vaccination against Bluetongue. The patterns found between perceived risk, personality traits and other farm and farmer characteristics were discussed in relation to the governance of animal health.     

Determinants of risk behaviour: effects of perceived risks and risk attitude on farmer’s adoption of risk management strategies

The importance of risk perception and risk attitude for understanding individual’s risk behaviour are independently well described in literature, but rarely combined in an integrated approach. In this study, we propose a model assuming the choice to implement certain risk management strategies to be directly driven by both perceptions of risks and risk attitude. Other determinants influence the intention to apply different risk strategies mainly indirectly, mediated by risk perception and risk attitude. This conceptual model is empirically tested, using structural equation modelling, for understanding the intention of farmers to implement different common risk management strategies at their farms. Data are gathered in a survey completed by 500 farmers from the Flanders region in Belgium, investigating attitudes towards farming, perceived past exposure to risk, socio-demographic characteristics, farm size, perceptions of the major sources of farm business risk, risk attitudes and the intention to apply common risk management strategies. Our major findings are: (i) perception of major farm business risks have no significant impact on the intention of applying any of the risk strategies under study, (ii) risk attitude does have a significant impact. Therefore, rather than objective risk faced and the subjective interpretation thereof, it is the general risk attitude that influence intended risk strategies to be implemented. A distinction can be made between farmers willing to take risk, who are more inclined to apply ex-ante risk management strategies and risk averse farmers who are less inclined to implement ex-ante risk management strategies but rather cope with the consequences and diminish their effects ex-post when risks have occurred.     

Downsizing decisions: The joint influence of equity incentives and behavioral biases

Although new investment can be viewed as a decision to pursue projects from a wide number of growth opportunities with easily discernible (and presumably preferable) risk profiles, downsizing (e.g., through layoffs, plant closings, asset divestitures, etc.) is a dichotomous choice to either abandon or continue an existing project where the relative risk between these options is not clear. Our evidence suggests that vega in the pre-downsizing period is associated with risky investment that necessitates future downsizing. We further find that contemporaneous vega is associated with a greater likelihood of downsizing. On the other hand, our evidence suggests that delta is a significant impediment to downsizing. We examine the influence of behavioral factors in the decision-making process and find downsizing decisions are discouraged by managerial overconfidence but encouraged by managers’ aversion to ambiguity. Finally, we investigate whether equity incentives and behavioral factors lead to better downsizing decisions. We find that downsizing firms with high ambiguity perform better after downsizing relative to their matched pair with lower ambiguity.     

Trust,happiness, and households’ financial decisions

A recent line of research highlights trust as an important element guiding the decision of households to invest into risky financial assets and insurance products. This paper contributes to this literature by identifying happiness as another key driver of the same decision. Using detailed survey data from a sample of Dutch households, we show that the impact of happiness on households’ financial decisions works in the opposite direction and is more economically important compared to trust. Specifically, happiness leads to a lower probability of investing into risky financial assets and having insurance, while trust has the usual positive effect found in the literature. Furthermore, the negative effect of happiness on the ownership of risky financial assets is about 6% higher compared to the positive equivalent of trust. Similarly, the negative effect of happiness on the ownership of insurance is 3% higher than the positive effect of trust.     

Risk perceptions,preferences and management strategies: evidence from a case study using German livestock farmers

We analyze the factors affecting farmers’ choice accounting for farm, farmer, and household characteristics as well as elicited risk perception and risk preferences. We consider three alternative hypothetical methods for assessing risk preferences to test the stability and behavioral validity of them. Our case study focuses on livestock farmers in the German region North Rhine-Westphalia. We find that risk preferences are context depending, i.e. differ across different fields of farm-level decision-making. Furthermore, our analysis shows that risk-averse farmers are more likely to prioritize on-farm risk management strategies over off-farm strategies. Moreover, higher risk perception, age, subjective numeracy, farm succession, farm size, and the proportion of rented land show a significant impact on farmers’ risk behavior     

Crop Price Indemnified Loans for Farmers: A Pilot Experiment in Rural Ghana

Farmers face a particular set of risks that complicate the decision to borrow. We use a randomized experiment to investigate (1) the role of crop‐price risk in reducing demand for credit among farmers and (2) how risk mitigation changes farmers’ investment decisions. In Ghana, we offer farmers loans with an indemnity component that forgives 50 percent of the loan if crop prices drop below a threshold price. A control group is offered a standard loan product at the same interest rate. Loan uptake is high among all farmers and the indemnity component has little impact on uptake or other outcomes of interest.     

A REGRET-THEORETIC EXPLANATION OF CORPORATE DIVIDEND POLICY

This paper uses Regret Theory to explain some survey results on managers' dividend policy decisions under uncertainty. Regret Theory suggests that when an individual chooses an action from a number of uncertain alternatives, his decision is influenced by the potential post-decision regret (pride) he feels on his inabilty (ability) to select the option with the best outcome. Based on this premise, we argue that (1) the decision to pay dividends and simultaneously raise venture capital from external sources is attributable to managerial aversion for regret at the failure of a risky investment opportunity implemented with internal funds generated by a conservative dividend policy; and (2) the decision to support dividends with borrowed funds when earnings are declining is motivated by the prospect that an improvement in the firm's financial condition will make the managers proud that their judgment has helped avert a potential crisis for the firm without any wealth loss to its shareholders.     

Household portfolio choices,health status and health care systems: A cross-country analysis based on SHARE

Health risk is increasingly viewed as an important form of background risk that affects household portfolio decisions. However, its role might be mediated by the presence of a protective full-coverage national health service that could reduce households’ probability of incurring current and future out-of-pocket medical expenditures. We use SHARE data to study the influence of current health status and future health risk on the decision to hold risky assets, across ten European countries with different health systems, each offering a different degree of protection against out-of-pocket medical expenditures. We find robust empirical evidence that perceived health status matters more than objective health status and, consistent with the theory of background risk, health risk affects portfolio choices only in countries with less protective health care systems. Furthermore, portfolio decisions consistent with background risk models are observed only with respect to middle-aged and highly-educated investors.     

Análisis de costos y estrategias productivas en la lechería de pequeña escala en el periodo 2000–2012

An accounting analysis was performed on the evolution and performance of productive, economic and marketing strategies implemented by small-scale dairy farmers in the peri-urban area of Texcoco, Mexico. Economic and production records for 1 023 lactation were obtained in two periods, 2000 and 2012. The general cost methodology was used to establish the accounting structures of these production systems, and the re-adjustment of values financial methodology through calculating deflated values based on data from the Mexican National Index of Consumer Prices. Evidence is presented that farmers in Stratum I defined as strategies not hiring temporary or permanent labour, as well as independence in the purchase of inputs (this Stratum produces 90% of its inputs). Stratum II reduced 3 of the main 4 items of the total production cost (feeding, medicines and breeding) and increased the mean profit per litre of milk ($ 2.00 MXN) through selling strategies. Stratum III defined as their strategies increased productivity (59%), a reduction in the cost (29%) of the main input (feed) and taking advantage of their productive scale to obtain a higher receipt of revenues for the farm.     

The Impact of Affective Reactions on Risky Decision Making in Accounting Contexts

In this study we examine whether managers' affective reactions influence their risk–taking tendencies in capital budgeting decisions. Prior research on risky decision making indicates that decision makers are often risk averse when choosing among alternatives that yield potential gains, and risk taking when the alternatives yield losses. The results reported here indicate that negative or positive affective reactions can change this commonly found risky behavior. Managers were generally risk avoiding (taking) for gains (losses) in the absence of affective reactions, as predicted by prospect theory. However, when affect was present, they tended to reject investment alternatives that elicited negative affect and accept alternatives that elicited positive affect, resulting in risk taking (avoiding) in gain (loss) contexts. The results also indicate that affective reactions can influence managers to choose alternatives with lower economic value, suggesting that managers consider both financial data and affective reactions when evaluating the utility of a decision alternative. These findings point to the importance of considering affective reactions when attempting to understand and predict risky decision making in accounting contexts.     

An examination of the impact of the Sarbanes–Oxley Act on the attractiveness of U.S. capital markets for foreign firms

We examine whether voluntary deregistrations after the passage of Sarbanes–Oxley Act of 2002 (SOX) were intended to benefit common shareholders by avoiding firms’ costs of complying with SOX or to protect the control rents of managers or controlling shareholders (MCOs). We find that, compared with foreign firms that maintained their SEC registrations, foreign firms that voluntarily deregistered on average had weaker corporate governance, had a significantly less negative stock market reaction when SOX was passed, and suffered a significant price decline when they announced their decision to deregister. We also find evidence indicating that the deregistrations were (to a lesser extent) motivated by firms’ compliance costs related to SOX. Taken together, our results suggest that both agency costs (that is, private benefit of control of the MCOs) and the compliance cost of SOX play a role in motivating foreign firms to withdraw from the U.S. market.     

Risk,responsibility and negative responses: a qualitative study of parental trust in childhood vaccinations

Abstract

Childhood vaccination programmes have benefits that far outweigh risks, in public health terms. However, some parents decide not to immunise their children. This paper explores the ways in which such parents talk about the perceived risks and benefits incurred by vaccinating (or not vaccinating) their children. Between 2013 and 2016, we undertook 29 in-depth interviews with non-vaccinating and/or ‘vaccine hesitant’ parents in Fremantle, Western Australia and Adelaide, South Australia. Our analysis of the interviews identified particular constructions of risk and responsibility. All interviews were transcribed and analysed using both inductive and deductive processes. Our analysis mirrors the chronological process through which parents navigate risk. We start with the concept of ‘responsibilisation’, which underpins parental engagement with decision-making and praxis. We then explore how responsiblisation takes the form of detailed and time-consuming ‘research’. Parents then attempt to navigate multiple and conflicting ‘risks’: the risk of vaccine-preventable diseases, risks associated with vaccination and risks associated with their own perceived lack of understanding. After engaging with risk, parents justify the decision and accept the associated ‘responsibility’. Parents use this sense of responsibility to navigate through the ‘responses’ of others, which we conceptualise as the risk of unwelcome consequences. In conclusion, parents have a reflexive understanding of the physical, psychological and socio-economic risks they incur as a consequence of their choice to either partially vaccinate, delay vaccination or reject vaccination for their children. They construct these risks with reference to particular discourses, engagement with expert opinion and lifestyle choices emblematic of late modernity. The risks they are willing to accept and the subsequent responsibility and blame they assume when choosing to abstain, or partially abstain, from vaccinating their children are, to the parents, coherent with their interpretation of best parenting practice.     

When time is (not) money: preliminary guidance on the interchangeability of time and money in laboratory-based risk research

The familiar adage that ‘time is money’ may not be entirely accurate according to research involving hypothetical choice: People’s decisions are less sensitive to temporal expenditures and outcomes than monetary ones. We provide a novel examination of whether similar patterns of risky choice are found for time and money when choices are consequential (i.e. monetary outcomes are obtained and temporal outcomes are experienced) – both for one-shot and repeated choices, over gains and losses. On the aggregate, across decision contexts (described and experienced), choices are similar for time and money. However, on the level of the individual, little relationship between risk preferences for time and money are observed. We discuss the theoretical and practical implications of these findings.     

Communication by Central Bank Committee Members: Different Strategies, Same Effectiveness?

The paper assesses the communication strategies of the Federal Reserve, the Bank of England, and the European Central Bank and their effectiveness. We find that the effectiveness of communication is not independent from the decision-making process. The paper shows that the Federal Reserve has been pursuing a highly individualistic communication strategy amid a collegial approach to decision making, while the Bank of England is using a collegial communication strategy and highly individualistic decision making. The European Central Bank (ECB) has chosen a collegial approach both in its communication and in its decision making. Assessing these strategies, we find that predictability of policy decisions and the responsiveness of financial markets to communication are equally good for the Federal Reserve and the ECB. This suggests that there may not be a single best approach to designing a central bank communication strategy.
