Regional Wage Convergence and Divergence: Adjusting Wages for Cost-of-Living Differences
研究了美国1980年代初期区域工资的趋同与分化，发现考虑区域价格后实际工资持续趋同，且工资差异缩小源于劳动力市场对工人特征评价的差异减小。
An examination of the divergence of U.S. regional fortunes in the early 1980s, showing that once regional prices are factored in, relative wage rates continue to converge across regions. The trend in regional wage variation is also shown to be attributable to declining differences in labor market valuations of worker attributes, rather than to shifts in the regional composition of the workforce.
