“Just give me a number!” Practical values for the social discount rate

A major reason the quality of cost‐benefit analysis (CBA) varies widely is inconsistent use of the social discount rate (SDR). This article offers guidance about the choice of the SDR. Namely, we recommend the following procedures: If the project is intragenerational (does not have effects beyond 50 years) and there is no crowding out of private investment, then discount all flows at 3.5 percent; if the project is intragenerational and there is some crowding out of investment, then weight investment flows by the shadow price of capital of 1.1 and then discount at 3.5 percent; if the project is intergenerational and there is no crowding out of investment, then use a time‐declining scale of discount rates; if the project is intergenerational and investment is crowded out, then convert investment flows during the first 50 years to consumption equivalents using a shadow price of 1.1, and then discount all of these flows at 3.5 percent, and discount all flows after the 50th year using time‐declining rates. We then compare current discounting practices of U.S. federal agencies with our estimates. Consistent use of the recommended rates would eliminate arbitrary choices of discount rates and would lead to better public sector decision‐making. © 2004 by the Association for Public Policy Analysis and Management.     

Behavior Problems in Children Exposed to Wife Abuse: Gender Differences

Family aggression patterns and behavior problems of children, aged 6-12, recruited from shelters for battered women (shelter group) were contrasted with three comparison groups of currently nonviolent families: two-parent, single-mother, and homeless. Girls who had been exposed to recent interparental wife abuse were predicted to show more internalizing and externalizing behavior problems than similarly exposed boys, based on recent literature. Homeless and shelter mothers reported the highest rates of parent-child aggression. Shelter girls obtained significantly higher total, internalizing and externalizing behavior problem ratings than shelter boys, and than two-parent and single-mother girls. Shelter boys obtained significantly higher internalizing ratings than two-parent boys. Shelter and homeless children were rated as having equivalent levels of behaviour problems. Across all groups, mothers' psychological adjustment was a better predictor of daughters' adjustment than that of sons. The study concluded that the assumption that preadolescent girls have greater immunity to psychosocial risk is unfounded.     

Taxes, Subsidies, and Listeners Like You: Public Policy and Contributions to Public Radio

Public radio in the United States receives both direct and indirect government funding. Direct subsidies come in the form of lump-sum and matching grants, while indirect subsidies proceed from tax revenues forgone on tax-deductible private donations. Each of these sources of government money affects charitable giving to public radio. This article estimates both of these effects, using data on 91 public radio stations in the United States during 1995. Data analysis shows that public funding to stations has a positive impact on private giving, but this impact rapidly decreases as the level of government subsidies increases. The analysis also indicates that increases in state tax rates correspond with significantly higher donation levels. This article explores the implications of these and other findings for policy makers, public administrators, and nonprofit managers.     

Elimination of 7-aminoflunitrazepam and flunitrazepam in urine after a single dose of Rohypnol

The hypnotic benzodiazepine flunitrazepam (Rohypnol) has been identified as the drug of choice for the purposes of "drugging" unsuspecting victims and raping them while they are under the influence of this substance. The objective of this paper was to study elimination of flunitrazepam and 7-aminoflunitrazepam in urine collected from ten healthy volunteers who received a single 2 mg oral dose of Rohypnol, to determine how long after drug administration 7-aminoflunitrazepam can be detected. A highly sensitive NCI-GC-MS method for the simultaneous quantitation of flunitrazepam (LOQ 100 pg/mL) and 7-aminoflunitrazepam (LOQ 10 pg/mL) in urine was developed. All samples were screened for benzodiazepines using optimized micro-plate enzyme immunoassay. The highest concentrations of 7-aminoflunitrazepam (70-518 ng/mL) and flunitrazepam (0.7-2.8 ng/mL) in urine were observed 6 h after drug administration in nine subjects and after 24 h in one subject. In six subjects 7-aminoflunitrazepam was detected up to 14 days after flunitrazepam administration, in one subject up to 21 days and in three subjects up to 28 days. In urine samples collected from six volunteers, flunitrazepam was detected three days after Rohypnol intake, in three subjects 24 h, and in one subject 5 days later. Benzodiazepine micro-plate enzyme immunoassay kit allowed the detection of flunitrazepam and metabolities 5 to 21 days after drug administration.     

Australia and the Emergence of the Modern Two-Party System

Although the Australian party system is accepted in some literature as a "classic" example of a two-party system, information about how this system came about does not feature prominently in international studies on political parties. It is here argued that Australia indeed blazed the trail for the two-party model by being the first to link parliamentary organisation directly to a mass electorate.
