This paper considers the problems involved in measuring trends over time in inequality in less developed countries. After considering some of the conceptual problems involved in choosing a measure of economic welfare, the period it should cover, and the statistical units to which it should be applied, the paper goes on to draw up a list of minimum data requirements for reaching reliable conclus...

During the past 30 years, the U.S. economy, along with the economies of other industrialized countries, has experienced several noticeable trends: an economic slowdown, a tremendous increase in the amount of information technology investment, and a increasing flow of workers from production to information sectors. With slow economic growth and fast IT capital accumulation, the so-called “inform...

An account is given of a variety of linear filters which can be used for extracting trends from economic time series and for generating de-trended series. A family of rational square-wave filters is described which enable designated frequency ranges to be selected or rejected. Their use is advocated in preference to other filters which are commonly used in quantitative economic analysis.

This paper scrutinizes the recently postulated link between the European Marriage Pattern (EMP) and economic success. A metastudy of the historical demography literature shows that the EMP did not prevail throughout Europe, its three key components did not always coincide, and its more extreme manifestations were associated with economic stagnation rather than growth. There is no evidence that ...

  Background: Statins have been effective medications in lowering serum total cholesterol (TC) concentrations across populations over time. The aim of this study was to estimate national and provincial trends in atorvastatin sales in Iran, to systematically quantify its relationship with socio-economic indicators, and changes in TC level.   Methods : In this retrospective ecological study, cond...

 ABSTRACT Background: Secular trends in stature, weight and mid upper arm circumference (MUAC) of 2397 school children (1268 boys and 1129 girls) of the same age (6.5-11.5 years) and sex in representative samples from primary schools of Shiraz (southern Iran) at an interval of 15 years (1988 vs 2003) are reported. Methods: Cross-sectional weight, height and mid upper arm circumference (MUAC) cu...

Extant analyses of the relation between economic conditions and population health were often based on annualized data and were susceptible to confounding by nonlinear time trends. In the present study, the authors used generalized additive models with nonparametric smoothing splines to examine the association between economic conditions, including levels of economic activity in New York State a...
