The fragile politics of addiction

Suppose the optimizing consumer only has local information, then what? Obviously, there will be a random element of consumption. The link between the frequency distribution of consumption by person and preference surface is worked out. Under convex preferences there will be a unimodal distribution and conversely. A local optimizing theory of addictive behavior is developed from nonconvex preferences. The resulting bimodal distribution of consumption implies a nonrobust outcome for median voter politics. Such a local optimizing model of addiction is compared with globally optimizing models of addiction.     

Risk compensation and the effectiveness of safety belt use laws: a case study of New Jersey

This paper investigates the effectiveness of New Jersey's mandatory belt use law (MUL) by testing specifically for: (1) a safety effect, and (2) a risk-compensation effect that could offset (in part) any safety impact. The main findings are that injury severity declined significantly in the 22 months following implementation of the MUL; but that accident frequency increased significantly. The increase in accidents may be explained only partially by increased driving mileage. These findings suggest that the real safety effect of the law may have been diluted by risk-compensating behavior.This paper is based on a study conducted for the New Jersey Office of Highway Traffic Safety by the Rutgers University Bureau of Economic Research.

Sex differences in intellectual and ego development in late adolescence

Perry's scheme of intellectual and ethical development was examined for sex differences with respect to areas of identity concern for which sex differences have been suggested: occupational choice, interpersonal relationships, and sexual identity. The content area of religion and ego development, as measured by Loevinger's sentence completion test (SCT), were also examined. Thirty-one females and 29 males participated. An interview format which applied Perry's unstructured approach to each of the four areas was utilized. Transcribed interviews and SCTs were rated blind. Structural as well as content analyses were performed. Structural analyses revealed no significant sex differences overall or by content area. However, multiple and stepwise regression analyses revealed patterns in which male personality processes consistently focused upon occupational issues while female processes focused upon interpersonal and sexual issues. Ego development was found to be highly correlated with intellectual development for men but unrelated for women. Content analyses suggest that women focus their interpersonal worlds developmentally upon issues of trust while men focus upon issues of rightness. Results are interpreted in the context of recent works by Gilligan concerning sex differences in development.Completing his Ph.D. in clinical psychology at Miami University.

Psychosocial Predictors of Emerging Adults' Risk and Reckless Behaviors

Past researchers have identified a range of psychosocial predictors of problem behaviors during adolescence, but have been less active in addressing this same issue in relation to the 18–25-year age group. The current study investigated risk and reckless behaviors in emerging adults using self-report measures and a cross-sectional design. Several of the major limitations associated with past research were overcome by sampling widely, making clear conceptual distinctions, avoiding confounds between predictors and criteria, developing more direct measures of key constructs, and controlling for demographic variables and for social desirability. In this sample of 375 emerging adults, risk behaviors were found to be reliably predicted by sensation seeking, but not by antisocial peer pressure, whereas the reverse pattern of association was more true in relation to reckless behaviors. Gender differences, especially in relation to the impact of social desirability considerations, are explored.
