Atmospheric aerosols: A literature summary of their physical characteristics and chemical composition

This report contains a summary of 199 recent references on the characterization of atmospheric aerosols with respect to their composition, sources, size distribution, and time changes, and with particular reference to the chemical elements measured by modern techniques, especially activation analysis

AGRICULTURAL ECONOMICS IN THE NEW MILLENNIUM: LESSONS FROM THE OLD MILLENNIUM

It is appropriate as we enter a new century that we reflect on the past one since our profession is nearly 100 years old: the American Association of Farm Economics was formally created in 1910. "Savvy through one hundred years of progress and experience" is one description that comes to mind. "Geriatric" is another word that might fit. I intend to highlight some broad topics that have occupied agricultural economists' teaching and research over the past 100 years, to reflect in a little more detail about our thoughts over the past 12 years as revealed in the presidential addresses at AAEA and SAEA annual meetings, to make some rather terse comments about current important issues as they relate to the issues of the past, and to conclude with some advice for the younger members of our profession and our association that may be of value in the new century. I emphasized the word may, because I am much less certain about the wisdom of my beliefs today than if I had been given the opportunity to give this talk 18 or even 11 years ago.Teaching/Communication/Extension/Profession,

Does relative deprivation induce migration?: evidence from Sub-Saharan Africa

This analysis revisits the decades-old relative deprivation theory of migration. In contrast to the traditional view that migration is driven by absolute income maximization, we test whether relative deprivation induces migration in the context of sub-Saharan Africa. Taking advantage of the internationally comparable longitudinal data from integrated household and agriculture surveys from Tanzania, Ethiopia, Malawi, Nigeria, and Uganda, we use panel fixed effects to estimate the effects of relative deprivation on migration decisions. Using per capita consumption expenditure and multidimensional wealth index as well-being measures, we find that a household’s migration decision is based not only on its absolute well-being level but also on the relative position of the household in the well-being distribution of the community in which it resides. We also discover that the effect of relative deprivation on migration is amplified in rural, agricultural, and male-headed households. Results are robust to alternative specifications including the use of Hausman Taylor Instrumental Variable (HTIV) estimator and pooled data across the five countries. Results confirm that the “migration-relative deprivation” relationship also holds in the context of sub-Saharan Africa. We argue that policies designed to check rural–urban migration through rural transformation and poverty reduction programs should use caution because such programs can increase economic inequality, which further increases migration flow
