最近的证据表明，各国的技能回报存在很大差异，但只有少数研究解释了技能回报的不同模式。使用2013年的STEP数据为加纳和肯尼亚，我们估计的因果关系的认知和非认知技能的劳动力市场的结果，通过控制重要的预定变量。我们发现，认知技能仍然是劳动力市场结果的重要预测因素，但其影响在很大程度上是由受教育年限介导的。我们的文件，劳动力市场的影响，非认知技能小于阅读熟练程度，但在劳动力市场的结果有很大的变化。有趣的是，我们发现，学校教育并不介导非认知技能的影响，这意味着这些技能中的大多数是在课堂外获得的。分解分析表明，当地劳动力市场的特点，如正式工作和熟练劳动力的需求，解释了大部分的异质性，而工作技能匹配质量起着重要的作用，在无法解释的部分。
Recent evidence indicates substantial heterogeneity in the returns to skills across countries, but only a few studies have explained the varying patterns in the return to skills. Using the 2013 STEP data for Ghana and Kenya, we estimate the causal effect of cognitive and noncognitive skills on a large set of labour market outcomes by controlling for important predetermined variables. We find that cognitive skill remains an important predictor of labour market outcomes but its effect is largely mediated by the year of schooling. We document that the labour market effects of noncognitive skills are smaller than reading proficiency, but with large variation across labour market outcomes. Interestingly, we show that schooling does not mediate the effect of noncognitive skills, meaning most of these skills are acquired outside the classroom. A decomposition analysis shows that local labour market characteristics, such as formal jobs and skilled labour demand, explains the lion share of the heterogeneity whereas the job-skill matching quality plays a significant role in the unexplained part.
