Skill Requirements across Firms and Labor Markets: Evidence from Job Postings for Professionals
研究了不同企业和劳动力市场对专业人才的技能需求差异，发现认知与社会技能互补且与薪酬、企业绩效正相关，技能变量能解释超出常用数据的薪酬与绩效差异。
We study variation in skill demands for professionals across firms and labor markets. We categorize a wide range of keywords found in job ads into 10 general skills. There is substantial variation in these skill requirements, even within narrowly defined occupations. Focusing particularly on cognitive and social skills, we find positive correlations between each skill and external measures of pay and firm performance. We also find evidence of a cognitive social skill complementarity for both outcomes. As a whole, job skills have explanatory power in pay and firm performance regressions beyond what is available in widely used labor market data.
