BACKGROUND The risk of end stage renal disease (ESRD) is increased among individuals with low income and in low income communities. However, few studies have examined the relation of both individual and community socioeconomic status (SES) with incident ESRD. METHODS Among 23,314 U.S. adults in the population-based Reasons for Geographic and Racial Differences in Stroke study, we assessed par...

When studying income differences and income distribution the self-employed are often excluded. There are good reasons for this, for example that incomes from self-employment are not reported to the same extent as income from being an employee. On the other hand it is a problem to exclude the self-employed if the group is large, the share who are self-employed differs between groups, and the ave...

Residential segregation, by definition, leads to racial and socioeconomic disparities in neighborhood conditions. These disparities may in turn produce inequality in social and economic opportunities and outcomes. Because racial and socioeconomic segregation are not independent of each other, however, any analysis of their causes, patterns, and effects must rest on an understanding of the joint...

Several studies have shown a positive relationship between mortality and episodes of income decline, unemployment, or poverty shortly before death or in the more distant past. Our objective was to analyse the mortality effects of earlier income changes more generally, net of the overall level. We used Norwegian register data that included individual histories of annual labour income and focused...

Abstract This paper tracks distributional changes over the last quarter of the twentieth century. We focus on three conceptually distinct distributions: the distribution of wages, the distribution of annual earnings and the distribution of total family income adjusted for family size. We show that all three distributions became less equal during the last half of the 1970’s and the 1980’s. This ...

Despite the widespread use of income as a measure of household welfare, there is much to recommend the use of consumption. Indeed, standard economic arguments suggest that consumption expenditure will better reflect expected lifetime resources and many economists have been unequivocal in advocating its use. Slesnick (1993), for example, suggests that ‘From a theoretical perspective it is more a...

This paper uses the 1998-99 Canadian National Population Health Survey (NPHS) data to examine the health-income relationship that underlies the absolute income hypothesis. To allow for nonlinearity and data heterogeneity, we use a partially linear semiparametric quantile regression model. Among more than dozen of socioeconomic variables, we find that family income, age and the food security sta...

Recognition of byproducts and their exploiting economic evaluation is one of basic requirements in documenting prospect of rangelands utilization. In this regard, the present study was performed to estimate the economic indices of exploiting byproducts production in Varnasa rangelands, Naghadeh, Iran. For this purpose, the economic data for calculating economic indices were collected after samp...

Opti-Money is a decision-support system for allocating assets that was developed at Bank Hapoalim, Israel’s largest bank. Based on customerand market-specific inputs, we solve a modified Markowitz-type nonlinear programming problem to produce optimal tailor-made investment portfolios in terms of asset classes. In its five years of operation, this mature system has provided excellent quantifiabl...
