Public Conservation Land and Employment Growth in the Northern Forest Region
研究了美国北部森林地区非都市县中公共保护用地对就业增长的影响，发现保护用地对净迁移率有轻微正向作用，但对就业增长无显著影响。
<i>We quantify the effect that public conservation lands have on employment growth in the Northern Forest region of the United States. A model of simultaneous employment and net migration growth is estimated with data on non-metropolitan counties from 1990 to 1997. Exogenous variables include the 1990 share of the land base in public conservation uses. We find that net migration rates were higher in counties with more conservation lands, but the effects are relatively small. No significant effect on employment growth is detected. As well, variables measuring changes in public timber harvests have no effect on employment growth.</i>
