Determinants of Income Growth in Metropolitan and Nonmetropolitan Labor Markets
用生产函数方法分析美国劳动力市场增长的决定因素，发现制造业投资促进非大都市增长，人力资本投资对大都市更重要，而公共资本投资作用不大。
Abstract This article analyzes determinants of growth across labor markets in the United States, using a production function approach based on four inputs: labor, manufacturing investment, human capital investment, and public capital investment. We find little role for public capital investment in growth, but that manufacturing investment spurred growth in nonmetropolitan areas, in contrast to metropolitan areas. We also find that human capital investment mattered more for metropolitan areas than for nonmetropolitan areas. Further, the presence of more colleges and universities, more household amenities, and lower tax rates are all found to have encouraged human capital accumulation in U.S. labor markets.
