How Much Does It Cost to Provide Antiretroviral Therapy for HIV/AIDS in Africa?
Background: Many African countries are rapidly expanding HIV/AIDS treatment programs. Empirical information on the cost of delivering antiretroviral therapy (ART) for HIV/AIDS is needed for program planning and budgeting.
Methods: We searched published and gray sources for estimates of the cost of providing ART in service delivery (non-research) settings in sub-Saharan Africa. Estimates were included if they were based on primary local data for input prices.
Results: 17 eligible cost estimates were found. Of these, 10 were from South Africa. The cost per patient per year ranged from 2,761. It averaged approximately 1,700/patient/year in South Africa. The most recent estimates for South Africa averaged $1,200/patient/year. Specific cost items included in the average cost per patient per year varied, making comparison across studies problematic. All estimates included the cost of antiretroviral drugs and laboratory tests, but many excluded the cost of inpatient care, treatment of opportunistic infections, and/or clinic infrastructure. Antiretroviral drugs comprised an average of one third of the cost of treatment in South Africa and one half to three quarters of the cost in other countries.
Conclusions: There is very little empirical information available about the cost of providing antiretroviral therapy in non-research settings in Africa. Methods for estimating costs are inconsistent, and many estimates combine data drawn from disparate sources. Cost analysis should become a routine part of operational research on the treatment rollout in Africa
Media Coverage of Law Enforcement Use of Force and Disability
Disability intersects with other factors such as race, class, gender, and sexuality, to magnify degrees of marginalization and increase the risk of violence. When the media ignores or mishandles a major factor, as we contend they generally do with disability, it becomes harder to effect change.This white paper focuses on the three years of media coverage of police violence and disability since the death of a young man with Down syndrome, named Ethan Saylor, in January 2013. After reviewing media coverage of eight selected cases of police violence against individuals with disabilities, the paper reveals the following patterns in the overall data:? Disability goes unmentioned or is listed as an attribute without context.? An impairment is used to evoke pity or sympathy for the victim.? A medical condition or "mental illness" is used to blame victims for their deaths.? In rare instances, we have identified thoughtful examinations of disability from within its social context that reveal the intersecting forces that lead to dangerous use-of-force incidents. Such stories point the way to better models for policing in the future. We conclude by proposing best practices for reporting on disability and police violence

On the Existence and Interpretation of the "Unit Root" in U.S. GNP
In this paper, we assess the degree to which four of the most commonly used models of risky decision making can explain the choices individuals make when faced with risky prospects. To make this assessment, we use experimental evidence for two random samples of young adults. Using a robust, nonlinear least squares procedure, we estimate a model that is general enough to approximate Kahnenman and Tversky's prospect theory and that for certain parametric values will yield the expected utility model, a subjective expected utility model and a probability-transform model. We find that the four models considered explain the decision-making behavior of the majority of our subjects. Surprisingly, we find that the choice behavior of the largest number of subjects is consistent with a probability-transform model. Such models have only been developed recently and have not been used in applied settings. We find least support for the expected utility model -- the most widely used model of risky decision making.
Are Business Cycles Symmetric?
This note shows that contrary to widespread belief there is little evidence that the business cycle is asymmetric. Using American data for the pre- and post-war periods and data on five other major OECD nations for the post-war period, we are unable to support the hypothesis that contractions are shorter and sharper than expansions. We conclude that there is not much basis for preferring some version of traditional cyclical techniques to more modern statistical methods.
The Changing Cyclical Variability of Economic Activity in the United States
This paper examines the changing cyclical variability of economic activity in the United States. It first shows that the decline in variability since World War II cannot be explained by changes in the composition of economic activity or by the avoidance of financial panics. We then show that increased automatic stabilization by the government, and the increased availability of private credit after World War II combined to stabilize consumption and reduce the variability of aggregate demand. The main argument of the paper holds that greater price rigidity in recent times may have contributed to economic stability by preventing destabilizing deflations and inflations. Empirical evidence is presented to support this proposition.
Equipment Investment and Economic Growth
Using data from the United Nations Comparison Project and the Penn World Table, we find that machinery and equipment investment has a strong association with growth: over l9&)?l95 each percent of GDP invested in equipment is associated with an increase in GDP growth of 1/3 a percentage point per year. This is a much stronger association than found between growth and any of the other components of investment. A variety of considerations suggest that this association is causal, that higher equipment investment drives faster growth, and that the social return to equipment investment in well functioning market economies is on the order of 30 percent per year.
