Abstr actThe shift and share method of regional analysis has definite appeal as a projection device, and has r e c e i v e d both considerable attention in the literature and wide usage in recent y e a r s . One of the principal c r i t i c i s m s of the technique is that the regional share component of the model is unstable over ~ time. The purpose of this paper is to provide further evidence on the debate regarding the stability of the share component using correlation analysis. This paper provides a test of the hypotheses of J a m e s and Hughes that (1) the component is possibly unstable for certain industries while being stable for others and (2) the stability v a r i e s across state or other geographic regions.The results do not support the conclusion that the share component is so highly unstable that the shift and share model is unusable as a projection technique. The tests indicate that the share component is stable for 23 of the 29 individual industries. The share component also proved stable for a majority of tests at the multi-state and state level of geographic disaggregation while being unstable for sub-state regions.
and the. As a biography the book is focused entirely on Lewis, and Clark, Sacagawea and the others are addressed principally in their interactions with Lewis. The expedition, and Lewis life as a whole, is placed within the broader context of Jeffersons presidency, the opening of the American west, and early Indian Policy.
The decades of the 1950’s and 1960’s constituted a period of transition for the Southeastern United States, during which the Region’s economy greatly reduced its dependence upon the agricultural sector. Agricultural employment declined by 52 percent, reducing its relative importance to the Region from 24 percent of total employment in 1950 to only 9 percent in 1967. Since regional employment expansion in the textile and apparel industries had an important positive impact in providing employment for many of those displaced by the declining agricultural sector, an examination of historical and future industry trends is relevant. In this paper we will identify the causal factors that have influenced the growth and regional allocation of textile and apparel employment in the United States since 1950 and examine possible national and regional industry growth trends to 1980.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
