Proposed treatment program for acute renal failure (ARF) in the United Republic of Tanzania as a model for sub-Saharan Africa

To date, no sustainable treatment program exists for kidney failure in countries in sub-Saharan Africa. No data are available on the incidence, prevalence or cause of chronic kidney disease (CKD). The world's focus has been on treating 'priority diseases' as defined by the United Nations Millennium Project and the World Health Organization because of their high mortality rates. This is understandable because HIV/AIDS, tuberculosis, diarrheal diseases and malaria claim majority of the lives; however, in many cases, the mortality is due to acute renal failure (ARF) as a consequence of the progression of these diseases. Moreover, to date, no data are available on mortality rates due to ARF as a consequence of these 'priority diseases.' Sustainable Kidney Care Foundation (SKCF), working with industry, institutions, universities and funding organizations, is in the process of establishing a pilot program for the treatment of acute renal failure (ARF) using peritoneal dialysis (PD) as the modality of choice with a special focus on treating children and women of childbearing age in the United Republic of Tanzania.     

The 4% rule: Does real estate make a difference?

This paper examines the wealth maximisation and preservation effects of including commercial real estate in retirement-phase portfolio management. Prior research addresses the role of real estate during the wealth-accumulation phase of the investor lifecycle; however, little is known about the contribution of real estate during the invest-and-spend, or decumulation, phase. To address this issue, we estimate short-fall risk based on the widely known 4% Rule. We use pricing data for multiple asset classes and simulation techniques, combined with a robust correlation structure, to examine: short-fall risk sensitivity to alternative spending rules; the impact of public vs. private real estate allocations; wealth preservation as an investment objective; and the effect of real estate on upside, or wealth maximisation, potential. We find short-fall risk in a decumulation portfolio decreases with substantial allocations to real estate. This result holds for a portfolio including either public or private real estate. Additionally, and under most conditions, the best performing decumulation-phase portfolios include a real estate allocation with both public and private real estate exposure. These results have significant implications for investors, whether they be retirees, plan administrators or endowments, as well as financial economists studying the lifecycle of investment decisions.     

Off‐farm labor market decisions and agricultural shocks among rural households in Kenya

Using household level data from rural Kenya, this article explores whether and how farm households respond to unfavorable agricultural production environments, including any ex post adjustments in off‐farm labor supply in response to unexpected weather shocks. While controlling for a wide range of educational, demographic, and other locational factors, we examine how long‐term weather conditions and specific rainfall shocks influence a household's decision to engage in, and their earnings from, the off‐farm labor market. We find that rural households engage in off‐farm work as a long‐term strategy to deal with the effects of anticipated weather conditions on their farming operations. The analysis does not reveal major short‐term adjustments in off‐farm engagement as a result of specific, unexpected rainfall shocks; these households do however rely on remittance income and petty agricultural wage labor under these circumstances. Holding other factors constant, and conditional on participation, households in areas with a more productive local agriculture tend to earn more from off‐farm work especially in the informal/business sector than their counterparts in regions with a less productive agriculture. As expected, a vibrant local economy in the form of public investment increases the probability of off‐farm participation.     

Complementarity and the Measurement of Individual Risk Tradeoffs: Accounting for Quantity and Quality of Life Effects

This paper considers the factors responsible for differences with age in estimates of the wage compensation an individual requires to accept increased occupational fatality risk. We derive a relationship between the value of a statistical life (VSL) and the degree of complementarity between consumption and labor supplied when health status serves as a potential source of variation in this relationship. Our empirical analysis finds that variations in an individual’s health status or quality of life and anticipated longevity threats lead to significant differences in the estimated wage/risk tradeoffs. We describe how extensions to the specification of hedonic wage models, including measures for quality of life and anticipated longevity threats, help to explain the diversity in past studies examining how the estimated wage–risk tradeoff changes with age.      

Geoeconomic Assumptions,Insecurity, and ‘Free’ Trade in Central America

The Central American Free Trade Agreement (CAFTA) exemplifies interconnections and contradictions between geopolitical and geoeconomic agendas, including security, democracy, and resource marketing. Central American sovereignty is selectively weakened as states are increasingly dependent on the US and must synchronise governance with the expectations of their most important trade partner or risk becoming defendants in international tribunals. Salvadoran and Costa Rican governments have been accused of upholding environmental regulations that impede the profit-earning of multinational corporations, while the Guatemalan state was charged with violating domestic labour laws. Nevertheless, criminal behaviour and impunity are widespread across the region and seldom provoke US action. Five years after CAFTA's implementation, there is evidence of the erosion of democracy, repression of civil society, and uneven distribution of trade costs and benefits. These results have led some analysts to conclude CAFTA must be renegotiated, while others recommend human and labour rights protocols accompany free trade agreements.     

Postauditing capital assets and firm performance: An empirical investigation

The argument presented in this paper is that the adoption of sophisticated postaudit procedures should be associated with improved firm performance. Based on a matched-pair experimental design, utilizing the Wilcoxon matched-pairs signed-ranks test and a newly developed statistic to test for a change point, empirical evidence is provided to support this argument.     

Right-to-Work Laws and Geographic Differences in Living Costs: Comment

A bstract . M. Reynolds and M. Edwards , commenting on R. J. Cebula's study of geographic differences in living costs in states with Right-to-Work Laws , seek to extend his results and explore the relevance of alternative variables. Cebula, in reply, addresses the comment and re-estimates the living cost impact of such laws, taking into account additional factors. Even after allowing for additional South/non-South differences , Cebula reports, the original basic model is resilient.     

An analysis of technology,productivity, and regulatory distortion in the interstate natural gas transmission industry: 1977–1985

The purpose of this paper is to provide the first comprehensive firm level analysis of cost structures and production in the interstate pipeline industry during the transition from price regulation to partial deregulation, 1977–85. The regulatory changes during this period were numerous and complex. We do not attempt to isolate the impact of any single change in regulation; rather, we examine how the regulatory environment, as a whole, affected the industry. Our study is based on a newly constructed panel of twenty-four interstate pipeline firms. We give particular attention to the impact of output change, technical change, scale economies, and non-optimal input allocation on total factor productivity growth and the implication of the 1978 Natural Gas Policy Act partial price decontrol relative to total wellhead price decontrol for residential, commercial, utility, and industrial consumers of natural gas, and for the transport industry itself. © 1998 John Wiley & Sons, Ltd.     

Agency Structure and Firm Culture: OSHA, EPA, and the Steel Industry

We compare models of Occupational Safety and Health Administration(OSHA) and Environmental Protection Agency (EPA) enforcementand compliance for steel plants during the 1980s. We find thatOSHA and EPA respond similarly to plant-level compliance andmeasures of hazardousness, but differently to firm-level complianceand risks of plant closing, and we relate the differences tothe agencies' differing organizational structures. Plant-levelcompliance is affected by enforcement pressure, compliance costs,and the firm's overall compliance behavior in similar ways forthe two regulatory areas, but environmental compliance was alsosensitive to plant size and risk of closing. Finally, we findthat the likelihood that a plant was in compliance with oneagency seemed at most weakly related to whether it was in compliancewith the other, but that plants likely to receive enforcementattention from one agency were also more likely to receive enforcementattention from the other agency.
