The Increasing Complementarity between Cognitive and Social Skills
利用1972年和1992年青少年技能数据与成年后结果，发现认知与社会技能的互补性增强，且认知技能需求增长仅惠及两者均高的个体；结合人口普查和职业数据，证实高认知高社交职业的就业和收入溢价显著增长。
Abstract Data linking 1972 and 1992 adolescent skill endowments to adult outcomes reveal increasing complementarity between cognitive and social skills. In fact, previously noted growth in demand for cognitive skills affected only individuals with strong endowments of both social and cognitive skills. These findings are corroborated using Census and CPS data matched with Dictionary of Occupational Titles (DOT) job task measures; employment in and earnings premia to occupations requiring high levels of both cognitive and social skill grew substantially compared with occupations that require only one or neither type of skill, and this emerging feature of the labor market has persisted into the new millennium.
