Voluntary purchase of public goods

This paper examines the application of Buchanan's ‘independent adjustment’ model of public good provision to individual donations to voluntary or non-profit organizations. An individual's donation function is a simple transformation of the Marshallian demand function; consequently donation functions ‘reveal,’ in principle, preferences for public goods. The existence of a tax-subsidy system sustaining a Pareto optimal level of provision is demonstrated, and the relationship to the existing subsidy scheme in the U.S. is examined. Finally, two implications of the model suggest that it is not appropriate as a representation of actual donor behavior.

Privatizing Federal Credit Programs: Why Sallie Mae?

The federal government subsidizes lending to a number of borrowers—notably students, farmers, and homeowners. Government‐sponsored enterprises issue the securities that channel capital to many of these privileged borrowers. One of the largest of these enterprises, the Student Loan Marketing Association (Sallie Mae), is scheduled to be wholly privatized by September 30, 2008. What explains the privatization of this enterprise? To identify distinctive features of Sallie Mae that permitted or abetted privatization, we investigate the structure, related capital market innovations, and growth of three government‐sponsored enterprises. We conclude that a unique structural feature of Sallie Mae may explain the pace of privatization. The core asset of Sallie Mae, the student loan, is guaranteed and subsidized by the government. The case of Sallie Mae is an instructive yet poorly understood example of how the federal government can leverage private‐sector assets and incentives to achieve public policy missions.     

Gender Differences in Peer and Parental Influences: Body Image Disturbance,Self-Worth,and Psychological Functioning in Preadolescent Children

The connections between body image disturbance and psychological functioning have been well established in samples of older adolescent girls and young women. Little is known, however, about body image in younger children. In particular, little is known about possible gender differences in preadolescent children. The current study explored self-reported body image disturbance and psychological functioning in relation to peer and parental influences in 141 elementary school-aged girls and boys aged 8–11. Results suggest that girls are more concerned about dieting and are more preoccupied with their weight than are boys. Girls also reported a greater drive for thinness and a higher level of family history of eating concerns than did boys. Correlations suggested that girls' experiences of body image concerns (body dissatisfaction, bulimia, and drive for thinness) were related to a number of factors (such as family history of eating concerns, peer influences, teasing, depression, and global self-worth) whereas boys' experiences of body image concerns were related to fewer factors. On the basis of these findings, the assessment and treatment of body image concerns in preadolescent children (especially girls) are of great importance. Implications for intervention and prevention programs are discussed.
