Power Sharing: Institutions,Behavior, and Peace

Grievances that derive from the unequal treatment of ethnic groups are a key motivation for civil war. Ethnic power sharing should therefore reduce the risk of internal conflict. Yet conflict researchers disagree on whether formal power‐sharing institutions effectively prevent large‐scale violence. We can improve our understanding of the effect of power‐sharing institutions by analyzing the mechanisms under which they operate. To this effect, we compare the direct effect of formal power‐sharing institutions on peace with their indirect effect through power‐sharing behavior. Combining data on inclusive and territorially dispersive institutions with information on power‐sharing behavior, we empirically assess this relationship on a global scale. Our causal mediation analysis reveals that formal power‐sharing institutions affect the probability of ethnic conflict onset mostly through power‐sharing behavior that these institutions induce.     

Marriage: Cause or mere indicator of future earnings growth?

The hypothesis that marriage increases men's earnings has contributed to legislative support for the Healthy Marriage Initiative (HMI). However, previous studies of this phenomenon have not controlled for many relevant characteristics that select men into marriage, nor have they focused on low‐income, unmarried fathers—the population targeted by HMI. We use the Fragile Families and Child Wellbeing Study, which measures many previously unobserved confounders, to test for a relationship between marriage and earnings. We use a variety of analytic strategies to control for selection (including differencing and propensity scores) and find no evidence of an effect of transitions to marriage on the earnings of unmarried fathers that differs from zero, either for the full sample or subsamples defined by race‐ethnic category and baseline cohabitation status. © 2009 by the Association for Public Policy Analysis and Management.     

Exchanging energy technology information on the internet

This paper describes the U.S. experience in using the Internet to disseminate international information about the technical and economic performance of newly demonstrated, energy efficiency technologies. It draws specifically on Oak Ridge National Laboratory's use of the Internet to promote the goals of the International Energy Agency's Center for the Analysis and Dissemination of Demonstrated Technologies (CADDET). Statistics from the U.S. CADDET home page system illustrates the potential of the Internet for contributing significantly to the goals of international information exchange. However, to reach a wider range of international and domestic audiences (beyond primarily upscale and educated professionals located in industrialized countries), Internet systems need to include other dissemination efforts that reach individuals in countries and organizations not currently using Internet services. In addition, more personal and customized information sources may be needed for providing users with the types of assistance and guidance required to translate knowledge of a technology's technical and financial performance into a decision to purchase, install, and use the technology.     

A profile of mentally disordered offenders admitted to inpatient psychiatric services in the United States

This research note presents data about mentally disordered offenders (MDOs) treated in inpatient psychiatric services. Data are derived from 1980 admission surveys by the Survey and Reports Branch, National Institute of Mental Health (NIMH). These data report for the first time inpatient services provided to MDOs by non-Federal general and private hospitals. A total of 31,773 MDOs were admitted, with 85% going to state and county mental hospitals. The largest group, including admissions for evaluation, was ISTs (58%), followed by mentally disordered prisoners (32%), NGRIs (8%), and MDSOs (3%). Women and whites tended to be overrepresented among MDOs as compared to prison and jail inmates. Clear diagnostic differences by legal status were found, with schizophrenia predominant among NGRIs (81%) and alcohol and drug abuse disorders more frequent among ISTs. Overall, state and county hospitals in both 1967 and 1980 were the primary locus of care for mentally disordered offenders.
