Relative finance wages and inequality: A role for intangibles?
研究了无形资本如何推动金融业相对工资增长，发现金融业中技能劳动与无形资本的互补性更强，加剧了收入不平等，且金融业虽占经济活动不足十分之一，却抵消了全国近三分之一的技能工资差距下降。
We investigate the role of intangible capital in the growth of relative finance wages using (i) a production framework entailing multi-level nesting and (ii) reduced-form analysis. We find that the degree and effects of complementarity between skilled labor and intangible capital are much more pronounced in finance than in the rest of the market economy. The stronger positive effects of such complementarity on finance skill premia are reinforced by relatively stronger unskilled labor substitution possibilities and technical change in the sector. Despite accounting for under a tenth of overall economic activity, finance offsets up to almost a third of declines in skilled–unskilled wage disparities nationally. We thereby find that finance contributes inordinately to income inequality. Intensified intangible capital growth in the industry stands to exacerbate this trend. Finally, our study suggests that financial deregulation, globalization, banking competition, and domestic credit expansion positively affect relative finance wages. Stricter labor market protection meanwhile dampens the impact of banking competition.
