Decision Making in the Pension Fund Board Room: An Experiment with Dutch Pension Fund Trustees

We ask how pension fund trustees deal with the booms and busts that funds encounter, and to what extent the decisions of pension fund trustees are affected by behavioral biases. We examine these issues by using a vignette-method field experiment among Dutch pension fund trustees. We find that trustees display choices that accord with the phenomenon of loss aversion and that trustees allow their choices to be affected by the forces of social comparison: the reserve position of their fund compared to the position of other funds has a significant influence in choosing a pension fund policy mix.pension funds;finance;governance;behavioral economics

A Mixed-Methods Investigation of Factors and Scenarios Influencing College Students’ Decision to Complete Surveys at Five Mid-Western Universities

Achieving respectable response rates to surveys on university campuses has become increasingly more difficult, which can increase non-response error and jeopardize the integrity of data. Prior research has focused on investigating the effect of a single or small set of factors on college students’ decision to complete surveys. We used a concurrent mixed-method design to examine (1) college students’ rationales for choosing to complete or not complete a survey presented to them and (2) their perceptions on the importance of multiple factors on their decision to complete or not complete surveys in a higher education setting. A total of 837 undergraduate and graduate students across five institutions in the state of Ohio completed the qualitative survey component, 808 completed the 72-scenario close-ended survey component, and 701 completed the rank- order component. The survey was administered in the classroom either at the beginning or end of the class period. The college students reported that the person administering, topic, incentives, length, and method of administration are the factors most influencing their decision to complete a survey. The undergraduate students were significantly more likely than graduate students to include incentives as one of the top three important factors in deciding to complete a survey. Qualitative results additionally revealed that the students felt day/time and location of survey request plays an important role in their decision. Recommendations are provided to survey administrators regarding potential effective and ineffective survey recruitment strategies

Reliability of the Q Force; a mobile instrument for measuring isometric quadriceps muscle strength

BACKGROUND: The ability to generate muscle strength is a pre-requisite for all human movement. Decreased quadriceps muscle strength is frequently observed in older adults and is associated with a decreased performance and activity limitations. To quantify the quadriceps muscle strength and to monitor changes over time, instruments and procedures with a sufficient reliability are needed. The Q Force is an innovative mobile muscle strength measurement instrument suitable to measure in various degrees of extension. Measurements between 110 and 130° extension present the highest values and the most significant increase after training. The objective of this study is to determine the test-retest reliability of muscle strength measurements by the Q Force in older adults in 110° extension. METHODS: Forty-one healthy older adults, 13 males and 28 females were included in the study. Mean (SD) age was 81.9 (4.89) years. Isometric muscle strength of the Quadriceps muscle was assessed with the Q Force at 110° of knee extension. Participants were measured at two sessions with a three to eight day interval between sessions. To determine relative reliability, the intraclass correlation coefficient (ICC) was calculated. To determine absolute reliability, Bland and Altman Limits of Agreement (LOA) were calculated and t-tests were performed. RESULTS: Relative reliability of the Q Force is good to excellent as all ICC coefficients are higher than 0.75. Generally a large 95 % LOA, reflecting only moderate absolute reliability, is found as exemplified for the peak torque left leg of -18.6 N to 33.8 N and the right leg of -9.2 N to 26.4 N was between 15.7 and 23.6 Newton representing 25.2 % to 39.9 % of the size of the mean. Small systematic differences in mean were found between measurement session 1 and 2. CONCLUSION: The present study shows that the Q Force has excellent relative test-retest reliability, but limited absolute test-retest reliability. Since the Q Force is relatively cheap and mobile it is suitable for application in various clinical settings, however, its capability to detect changes in muscle force over time is limited but comparable to existing instruments

Tailor-to-Target: Configuring Collaborative Shareholder Engagements on Climate Change

We study collaborative shareholder engagements on climate change issues. These engagements involve coalitions of investors pursuing behind-the-scenes dialogue to encourage target firms to adopt environmental sustainability practices. Drawing on a unique dataset of 553 engagements coordinated by the United Nations-supported Principles for Responsible Investment (PRI)—and an innovative mixed-methods approach integrating fuzzy-set Qualitative Comparative Analysis (fsQCA) with regression analysis and qualitative interviews—we investigate how four coalition composition levers (coalition size, shareholding stake, experience, local access) combine to enable or hinder engagement success. We find that successful coalitions use four configurations of coalition composition levers that are tailored to target firms’ financial capacity and environmental predispositions—i.e., target firms’ receptivity. Unsuccessful configurations instead emphasize single levers at the expense of others. Drawing on qualitative interviews, we identify three mechanisms (synchronizing, contextualizing, overfocusing) that plausibly underly the identified configurations and provide investor coalitions with knowledge about target firms and their local contexts, thus enhancing communication and understanding between investor coalitions and target firms. Our study contributes an emerging “tailor-to-target” theory of collaborative shareholder engagement that extends the literature by showing the importance of designing investor coalitions for effective climate-related engagement; and the value of conceiving coalitions as different configurations of the same levers that can fit a target firm’s receptivity. From a practical perspective, our study prompts investors to move beyond one-size-fits-all approaches to instead tailor their engagement strategies to target firms’ receptivity
