The microeconomics of distribution: A simulation of the farm economy

A simulation model that incorporates both production and consumption behavior of farm households in Taiwan is presented. The model is used to analyze the effects of policy instruments (price supports, minimum wages, taxes, subsidies, demographic policies, and land and capital redistribution) on the aggregate values of the endogenous variables of the system—the supplies of output and labor, the demands of factors and consumption, income and expenditure—and their distribution among households. The model differs from other simulation models in that it is based on microsimulation, in which the joint distribution of individual household characteristics such as farm-specific prices, initial endowments of land and capital, and numbers of workers and dependents, is explicitly taken into account. As a result, the model is capable of capturing the distributional as well as aggregate impacts of policy changes.     

How to Approximate a Histogram by a Normal Density

Which normal density curve best approximates the sample histogram? The answer suggested here is the normal curve that minimizes the integrated squared deviation between the histogram and the normal curve. A simple computational procedure is described to produce this best-fitting normal density. A few examples are presented to illustrate that this normal curve does indeed provide a visually satisfying fit, one that is better than the traditional , s answer. Some further aspects of this procedure are investigated. In particular it is shown that there is a satisfactory answer that is independent of the bar width of the histogram. It is also noted that this graphical procedure provides highly robust estimates of the sample mean and standard deviation. We demonstrate our technique by using data including Newcomb's data of passage time of light and Fisher's iris data.     

A Method for Generating High-Dimensional Multivariate Binary Variates

Examples are given of the need for simulating correlated binary variates with different given marginal expectations and pairwise correlations. An algorithm is then presented for generating such variates. The algorithm may be used to generate variates of any dimension.     

The use of nativity data to estimate ethnic characteristics and patterns

Until recently, nativity data for the first and second generations (the foreign stock) have been the primary source of census information on white ethnic groups in the United States. With the development of an ancestry item, it is now possible to deal with all generations regardless of birthplace. The 1979 Current Population Survey provides a rare opportunity to cross-tabulate the results obtained from each system in order to determine the degree of overlap in the populations and the extent to which inferences about the social characteristics of ethnic groups are altered. The degree of overlap varies enormously among groups, but the results show that inferences based on nativity data are fairly close to those that would be obtained with the use of the ethnic ancestry item. This is an encouraging result for researchers obliged to use nativity data in working with earlier censuses.     

Reinsurance and the liability insurance crisis

Insurance-industry accounts of the liability insurance crisis of the mid-1980s often cite disruption of supply in reinsurance markets as an important contributing factor. Economic theories of the crisis have not explored this explanation for the severity of the crisis. This article investigates the extent to which events in reinsurance markets affected liability insurance market outcomes. It documents significant shocks to reinsurance supply in the early 1980s and finds evidence of subsequent disruptions to the price and availability of reinsurance. Regression analysis of liability insurance profitability over the time period supports the hypothesis that problems in reinsurance markets played an important role in the crisis.     

AIDS KNOWLEDGE AND ATTITUDES AMONG CANBERRA SECONDARY SCHOOL STUDENTS

This paper reports findings from a study of 1,014 Canberra secondary school students in 15 government and private schools. Open-ended responses concerning students' understanding of AIDS, and their views regarding prevention, are presented and discussed. Data on source of AIDS information are also investigated. In general, students understand AIDS as sex-linked, that it involves transmission through the blood, and that there is no cure for it. They espouse more research and education as the main preventive measures, although males also propose homophobic solutions. Teachers and television are the primary sources of AIDS information. Differences by sex of respondent and school type are reported and implications for school-based AIDS education policies are suggested.     

Social work students’ perceptions of obesity

Research indicates that mental health and medical professionals often hold negative views of overweight or obese people. Little is known about weight prejudice among social work students. In order to address this gap in the literature, this study examines the attitudes of Bachelor of social work and Master of social work students (n = 250) toward persons who are overweight and/or obese. Consistent with the literature, findings indicate generally those with higher body mass index scores are more likely to believe that obesity is beyond their control. Further, although age was correlated with Beliefs About Obese People scores, it was not a significant predictor. Implications for social work social justice and cultural competency curriculum are discussed.     

Athletes’ Perceptions of National Collegiate Athletic Association–Mandated Sickle Cell Trait Screening: Insight for Academic Institutions and College Health Professionals

Abstract

Objective: The study objective was to explore athletes’ perspectives of National Collegiate Athletic Association (NCAA)–mandated sickle cell trait (SCT)–screening policy by examining race- and gender-related differences in athletes’ perceptions regarding risk of having SCT and concern about loss of playing time. Participants: Participants were 259 athletes at a southeastern United States campus during April–August of 2010. Methods: Athletes completed a 21-question survey. Results: The majority of athletes (81.7%) perceived that they would have a high level of concern if found to carry the SCT. African Americans were 9.07 times more likely than Caucasians to perceive risk of having the SCT. The majority of athletes disagreed (38.4%) or did not know (50.8%) if they would lose playing time related to carrying the SCT. Conclusion: Campus health professionals must be aware of athletes’ perspectives on NCAA's SCT screening so that athletes are not unnecessarily subjected to stress or harm.
