Abstract:
In the presence of a risk-free asset the investment opportunity set obtained via the Markowitz portfolio optimization procedure is usually characterized in terms of the vector of excess returns on individual risky assets and the variance-covariance matrix. We show that the investment opportunity set can alternatively be characterized in terms of the vector of Sharpe ratios of individual risky assets and the correlation matrix. This implies that the changes in the characteristics of individual risky assets that preserve the Sharpe ratios and the correlation matrix do not change the investment opportunity set. The alternative characterization makes it simple to perform a comparative static analysis that provides an answer to the question of what happens with the investment opportunity set when we change the risk-return characteristics of individual risky assets. We demonstrate the advantages of using the alternative characterization of the investment opportunity set in the investment practice. The Sharpe ratio thinking also motivates reconsidering the CAPM relationship and adjusting Jensen's alpha in order to properly measure abnormal portfolio performance.

Abstract:
Even though the entrepreneurship literature places much emphasis on opportunity recognition, little is known about how entrepreneurs actually evaluate opportunities. This study uses a cognitive approach to examine opportunity evaluation, as the perception of opportunity is essentially a cognitive phenomenon. We present a model that consists of four independent variables (overconfidence, belief in the law of small numbers, planning fallacy, and illusion of control), a mediating variable (risk perception), two control variables (demographics and risk propensity), and the dependent variable (opportunity evaluation). We find that illusion of control and belief in the law of small numbers are related to how entrepreneurs evaluate opportunities. Our results also indicate that risk perception mediates opportunity evaluation.

Abstract:
A study was performed to assess the predictive validity of the Responsibility scale of the California Psychological Inventory by examining the relationship between standard scores and decision-making behaviour under varying conditions of risk. Subjects were required to make risky decisions on three different tasks, one where there was an opportunity to seek additional information to reduce risk for self, one where there was no opportunity to seek information for self, and one where a risky decision was made on behalf of another person. Responsibility scores correlated significantly with decision-making behaviour but only on tasks measuring risk-taking for the self.

Abstract:
Abstract We assessed the effect of a daytime sleep opportunity on planning and risk-related decision-making in emerging adults using multiple neurobehavioral assessments. A total of 136 healthy emerging adults (20.0 ± 1.5 years), 65% female, performed the Risky-Gains Task and the Tower of London test twice. Between these assessments, they were randomized to either have a sleep opportunity monitored by polysomnography (Sleep group, n = 101) or to stay awake (Wake group, n = 35). During Test 2, in comparison to the Sleep group, the Wake group showed increased sleepiness, worse planning ability and more decrease in reaction times when selecting risky choices. Changes in Tower of London test steps used and Risky-Gains Task response time correlated with the number of central and frontal fast sleep spindles, respectively. These results indicate that among emerging adults who commonly have poor sleep patterns, a daytime sleep opportunity was related to better planning ability, better psychomotor vigilance and stable response speeds in risk-related decision-making. Changes in planning and risk-related decision-making correlated with the number of sleep spindles during the nap, supporting a specific role for sleep in modulating planning and potentially other higher-order cognitive functions.

Abstract:
AbstractWe posit the opportunity cost of time required to manage risky investments, including conducting research and performance monitoring, as a potential explanation for the equity premium puzzle. An economic agent, who should allocate a limited amount of time to labor, leisure, and risky investment, is subject to the opportunity time cost of investment activity, which is foregone labor or leisure. Our model envisages its impact on equity premium and volatility in the presence of such a time constraint, in particular, with closed-form solutions to the risky asset returns, volatility, and risk-free rate in a simple equilibrium framework wherein agents have log utility. The model is shown to yield excess return and volatility consistent with historical values observed in the U.S. stock market, even with a small amount of time cost. In addition, the model enables us to sort out the impact of endogenous labor/leisure choice on return dynamics by comparing it with the exogenous labor income case.

Abstract:
Socio-ecologic, socio-economic, and socio-technical transitions are opportunities that require fundamental changes in the system. These will encounter matters associated with security, service adoption by end-users, infrastructure and availability. The purpose of this study is to examine and overcome the risks to take advantage of opportunities through the novel Risky-Opportunity Analysis Method (ROAM). A novel quantitative method is designed to determine when, after making some changes, the risks become acceptable so that the opportunity does not deviate from the objectives. The approach provided a quantitative evaluation of the possible changes in parallel with digitization, towards providing a green Service Supply Chain (SSC). The result of ROAM shows that the most cost-effective change to increase the resilience of the system is a solution (SMS) which is different from that identified by a TOPSIS multi-criteria method. Real-word decisions in change management should tackle the complexity of systems and uncertainty of events during and after transition through a careful analysis of the alternatives. A case-study was carried out to evaluate the alternatives of an ancillary service in the Payment Service Providers (PSP). The comparison of the ROAM results with the traditional TOPSIS of the case-study unveils the priority of the ROAM in practice when the alternatives are Risky-Opportunities. The existing risk assessment tools do not take advantage of risky opportunities. To this aim, the current article introduces the term Risky-Opportunity, and two indexes—Stress and Strain—of the alternatives that are designed to be employed in the new quantitative ROAM approach.

Abstract:
The aim of the study is to evaluate the relationship between early childhood teachers’ risky play experiences, their injury histories in their childhood and risky play management strategies they used as a teacher. 190 early childhood teachers participated in this study. Data were collected through a semi- structured interview form. Only play with great heights (climbing up a tree) and play with high speed (swinging on playground swings) were included in the semi-structured interview form. Scenario-based, black and white drawings were used as a data collection tool. Results showed that teachers’ risky play histories, injury histories and their management strategies at play with great heights are independent of each other. However, a different pattern was identified for play with high speed (swinging on playground swings). This result provides an opportunity to discuss whether teachers’ injury histories at specific risky play categories, may affect their risky play management strategies.
