Multiperiod migration patterns: the timing and frequency of household responses

"The structure of intertemporal patterns of household migration responses is empirically examined. The findings indicate that migration decisions are often related to changes in household conditions in both prior as well as following periods, are dependent on the duration of household status characteristics (e.g., marital status) and not just their presence at any point in time, and finally that migration response in any particular period very often differs among households as a result of differences in the underlying structure of migration frequency behavior. These findings suggest that inferences based on comparisons of household migration responses over only a single period of time are incomplete, possibly to the point of being misleading." The study is based on a calculation of "the distribution of migration patterns between 1976 and 1979 for a sample of 4,739 households in the [U.S.] Michigan Panel Survey on Income Dynamics (PSIC)."     

Population growth among U.S. regions and metropolitan areas: a test for causality

ABSTRACT This paper explores theories of population growth, and implied economic growth, among the major U.S. metro areas and regions. One set of theoretical arguments favor the growth of large cities, while an alternative set of arguments favor the growth of the smaller urban areas. Still another set of arguments combine economic space and urban size in the concept of regional growth centers as the engines of regional growth. Granger causality tests are applied to determine the role of urban size or growth centres as engines of regional growth. The test results indicate no causal relationship exists.     

SOURCES OF THE QUARTZITE OF SOME ANCIENT EGYPTIAN SCULPTURES

This article reports the results of analysis of samples collected from some Egyptian quartzite artifacts. such as statuary, dating from the New Kingdom. Most of the artifacts are located in Upper Egypt, but the results of analysis suggest that, until the middle of the fourteenth century B.C., the quartzite came from a more distant quarry near Cairo rather than from the quartzite quarries located near Aswan in Upper Egypt.     

Australian Federal Government Road Funding 1972–1986

Increasing Commonwealth Government desire to establish national priorities for road expenditure was successfully thwarted by constitutionally powerful State Governments until the early 1980s Political considerations interfered with the consistently efficiency-orientated national priorities suggested by the Commonwealth Government's advisory organisation. The paper evaluates efficiency, equality and equity as potential bases for road funding, before analysing what happened over the period 1972-86. The 1982 ABRD program allowed the Commonwealth to impose its priorities in an area of State constitutional authority.
