Private provision of public goods can be efficient

Economists have long believed that private provision of public goods will be inefficient, though recently some have argued that altruism may mitigate the inefficiencies. Without altruism, agents contribute to the point where marginal cost equals their private marginal benefits. With altruism, they contribute more and hence are closer to the point where marginal cost and total marginal benefits are equated. In an earlier paper (Bagnoli and Lipman, 1989), we showed that private provision need not be inefficient. In a very natural model of private provision without altruism, we showed that the set of (undominated perfect) equilibrium outcomes is identical to the core. Here we consider the effect of altruism on private provision. Altruism essentially creates more public goods because the well-being of others becomes a public good. We show that our model of private provision still has efficient equilibria under a wide variety of circumstances. Interestingly, the equilibria may be inefficient when agents are concerned about the effect of private provision on the distribution of wealth. Intuitively, the game we consider is a very powerful instrument for efficient private provision, but must be supported by other instruments if the set of public goods is expanded too far.We wish to thank Jim Andreoni, Ted Bergstrom, and an anonymous referee for helpful comments and to acknowledge financial support from the National Science Foundation through NSF Grant SES-8520296.

Cognitive-behavioral skills,social supports,and child abuse potential among mothers of handicapped children

This study examined the relationship among cognitive functioning, social support networks, and risk for child abuse in a sample of 92 mothers of developmentally disabled children. Mothers found to be at highest risk for child abuse potential tended to score low on cognitive skills, social support networks, and life satisfaction. Beck Depression Inventory scores were found to explain 57% of the variance in the Child Abuse Potential Scores. Single mothers differed significantly from married mothers on child abuse potential, relationship satisfaction, community involvement, and loneliness. The authors discuss implications of the study and the need for future research with families of handicapped children.     

The missing link between job satisfaction and correctional staff behavior: The issue of organizational commitment

Over the past twenty years, several empirical studies have examined the consequences of job satisfaction among correctional staff. When looking at worker behavior in other disciplines, though, it is commonplace to include both job satisfaction and organizational commitment. However, very few studies about correctional staff behavior include both concepts. This paper discusses job satisfaction and organizational commitment, and addresses the link between these concepts as it relates to correctional staff attitudes and behaviors. Further, a discussion of measurement issues and recommendations for future research is presented. This is a revision of papers presented at the 1998 American Society of Criminology annual meeting in Washington, D.C. The authors would like to thank the anonymous reviewers for their comments and suggestions.
