Different Paths? Human Capital Prices, Wages, and Inequality in Canada and the United States
研究了近三十年加拿大和美国在人均GDP增长、技能溢价和不平等方面的差异，发现主要源于两国高技能人力资本相对价格的不同路径，而非数量差异。
In the last three decades, Canada and the United States showed different paths in per capita gross domestic product growth, skill premiums, and inequality. Worker quality and price differences both play a role but are difficult to distinguish. Human capital prices and quantities are estimated using methods we developed previously. In the United States, there was faster growth and a much more rapid rise in skill premia and inequality. This was primarily due to different paths for the relative price paid to rent high-skilled human capital in the two countries, rather than differences in relative quantities.
