EMPLOYMENT, INCOME, AND MIGRATION IN APPALACHIA: A SPATIAL SIMULTANEOUS EQUATIONS APPROACH*
研究了1990-2000年间阿巴拉契亚地区就业、迁移和家庭收入的决定因素，发现三者相互影响且受邻近县经济状况制约，为区域合作政策提供依据。
ABSTRACT Appalachia remains a symbol of poverty in the midst of prosperity. During the 1990s it fell further behind the rest of the nation. Persistent poverty during a period of strong growth is a serious as well as an interesting subject to study. We examine determinants of growth in Appalachia between 1990 and 2000. We show that employment, migration, and median household income were jointly determined by regional covariates and that county economic conditions were conditional on the performance in neighboring counties. One conclusion is that regional cooperation and geographically focused programs may yield the greatest returns to policy investments.
