Abstract High-ability agents are more likely to achieve early success in risky experimentation, but learn faster that their project is not promising. These counteracting effects give rise to a signaling model with double-crossing property. This property tends to induce homogenization of quitting times between types, which in turn leads to some pooling in equilibrium. Low-ability agents may hold out to continue their project for the prospect of pooling with the high type, despite having a negative instantaneous net payoff. A war-of-attrition mechanism causes low-ability agents to quit only gradually over time, and to stop quitting for a period immediately before all agents exit.

This study aims to examine the role of managerial in firm decisions. This study recognizes that managerial plays an important role in corporate decision making. Decisions carried out by the company are not only influenced by the manager's explicit mandate to maximize firm value, but also by the manager's ability to manage the company. In previous research it was found that high-ability and low-ability managers have opposite effects on firm behavior and firm value. High-ability managers accept risk-taking whereas low-ability managers refrain from taking risks. Managerial Ability in this study was measured using DEA (Data Envelopment Analysis) while for firm risk-taking behavior using the return on assets (ROA), return on equity (ROE), and research and development costs to total assets (R&D). The model used in this study is a causality model or the relationship of influence between research variables. The proposed model is analyzed using the Structural Equation Model (SEM) causality technique. This research was conducted on manufacturing companies listed on IDX (Indonesian Stock Exchange) in 2013-2017. However, unlike previous studies, the results of this study indicate that highly capable managers play a role in minimizing corporate risk taking. This research contributes as a reference for Indonesian corporate investors and also regulators as a reflection of the effectiveness of regulations made in Indonesia.

General problem-solving steps consist of understanding the problem, developing a plan, implementing the plan and checking the result. The purpose of this study is to explore how well Indonesia junior secondary school students apply these four steps in solving mathematical problems, especially on plane geometry topics. Using a qualitative approach, with a sample of nine students, of which three students were from the low mathematics achievement category, three from the medium and three from the high category, were given a test and instructed to write the answers to each question step by step. The results were described and categorized into four groups. The first group consisted of students who used all of the four steps. The second and the third were for students who used the first three steps or the first two steps respectively. The fourth group was for those who could only show the first step. The study indicated that for this sample the level of mathematic ability corresponded to how the students applied their problem-solving steps. It was found that students with high ability were included in the first group, while those with moderate ability were in the second group. Low ability students were categorized into group four. Nevertheless, there was one student with high ability who did not to do the checking step and there was one student with low ability who was able to develop a plan.

It is widely held that the professional athlete who is traded tends to perform better against the trading team than against other teams. Two psychological explanations for this hypothesis were advanced (a separation-hostility mechanism and an esteem loss-counteraction mechanism). Data were examined for 47 (30) professional baseball players over a 2-yr. (3-yr.) period. Support for the hypothesis was weak across the entire sample; however, some support appeared among players who (a) were traded for the first time, (b) had long tenure with the trading team, (c) were young, and (d) had high ability. Somewhat stronger positive results were found for individuals who met two or more of the conditions favorable to the hypothesis. As predicted, results attenuated over time.

Selective education research has demonstrated that students are aware of the low status of being allocated to a low-ability school. Recent data in Guyana has shown that low-ability school attendance is associated with low rates of student attendance, retention, and graduation. This study aims to understand the effects of ability grouping on students by comparing the psychosocial well-being of students from different ability schools. Data was collected from a sample of 193 adolescents (70 males and 123 females) aged 13-18 from four secondary schools; representing the four school ability rankings. It was hypothesised that student psychosocial well-being would be significantly lower in low-ability schools compared to high-ability schools. Unexpectedly, the results indicated that the highest ability school had significantly lower psychosocial well-being than the other lower ability schools. The results may be potentially explained by the theory of Big-Fish-Little-Pond Effect, however confirmation in future research is warranted.

Eight story problems in a drawn format, eight matching problems in a verbal format, and eight matching problems in a telegraphic format were administered to 854 students in tests at each grade from 3 to 7. Scoring was based on the choice of correct operations to solve the problem. Readers of high ability, as measured by a reading test, chose correct operations more often than low-ability readers. The drawn format was easier than the other two formats. A significant format-by-reading-ability interaction revealed that the advantage of the drawn format was greater for low readers than for high readers.
