Age Patterns in Risk Taking Across the World

Abstract: Epidemiological data indicate that risk behaviors are among the leading causes of adolescent morbidity and mortality worldwide. Consistent with this, laboratory-based studies of age differences in risk behavior allude to a peak in adolescence, suggesting that adolescents demonstrate a heightened propensity, or inherent inclination, to take risks. Unlike epidemiological reports, studies of risk taking propensity have been limited to Western samples, leaving questions about the extent to which heightened risk taking propensity is an inherent or culturally constructed aspect of adolescence. In the present study, age patterns in risk-taking propensity (using two laboratory tasks: the Stoplight and the BART) and real-world risk taking (using self-reports of health and antisocial risk taking) were examined in a sample of 5227 individuals (50.7% female) ages 10–30 (M = 17.05 years, SD = 5.91) from 11 Western and non-Western countries (China, Colombia, Cyprus, India, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the US). Two hypotheses were tested: (1) risk taking follows an inverted-U pattern across age groups, peaking earlier on measures of risk taking propensity than on measures of real-world risk taking, and (2) age patterns in risk taking propensity are more consistent across countries than age patterns in real-world risk taking. Overall, risk taking followed the hypothesized inverted-U pattern across age groups, with health risk taking evincing the latest peak. Age patterns in risk taking propensity were more consistent across countries than age patterns in real-world risk taking. Results suggest that although the association between age and risk taking is sensitive to measurement and culture, around the world, risk taking is generally highest among late adolescents.

Regulation Fair Disclosure, Analyst Following, and Analyst Forecast Dispersion

Abstract: This paper presents preliminary evidence of the effect of Regulation Fair Disclosure (FD) on the quantity and quality of firm‐specific information released to the market by comparing analyst forecast data from pre‐FD to post‐FD time periods. By prohibiting selective disclosure of material information to privileged individuals, the Securities and Exchange Commission intends to provide a level playing field to all investors. However, opponents argue that FD has a negative impact by decreasing the quantity and quality of publicly available information. Consistent with this argument, we document a decrease in analyst following and an increase in forecast dispersion following the passage of FD.

Covalent amphiphilic polymer networks

Abstract: The recent literature on chemically cross-linked amphiphilic polymer networks is reviewed The main subjects covered are network synthesis, characterization, modeling and applications Special mention is made to more modern methods for amphiphilic network synthesis and in particular to those involving controlled polymerization techniques A key question regarding synthesis is which method gives the most perfect networks On the characterization side is the issue of microphase separation of amphiphilic networks in water and the morphologies obtained in these systems, in comparison with the morphologies of amphiphilic linear block copolymers in water Major recent advances: The most important developments of the past year in the field of amphiphilic polymer networks involved mainly new syntheses: cross-linked stars of various star architectures, cross-linked linear chains of various architectures and compositions, poly(tetrahydrofuran)- and poly(propylene fumarate)-based networks, tricomponent networks containing silicon, and cross-linked poly(acrylic acid)-grafted Pluronics A first crude model was also developed which shows that amphiphilic networks prefer to be mostly in the microphase separated state Extensive and systematic experimental studies on network microphase separation are yet to be performed
