INTERINDUSTRY FACTOR MOBILITY AND TECHNOLOGICAL CHANGE: EVIDENCE ON WAGE AND PROFIT DISPERSION ACROSS U.S. INDUSTRIES, 1820–1990
利用1820-1990年美国制造业数据，研究行业间要素流动如何影响工资和利润差异，发现19世纪工业化提高了流动性，而20世纪工业化则降低了流动性。
Interindustry factor mobility is a crucial determinant of the income-distribution effects of exogenous changes in relative commodity prices. This examination of interindustry variation in wages and profits using data from manufacturing industries from 1820 to 1990 suggests that interindustry factor mobility may be strongly related to the processes of industrialization. Development in the nineteenth century produced a sharp rise in mobility (a decline in interindustry wage and profit differentials) due to rapid improvements in transportation and the introduction of factory production. Twentieth-century industrialization, involving greater reliance on specialized equipment and knowledge, reduced levels of interindustry mobility.
