我们衡量一家按计件工资支付工人工资的公司内，将不同类别的员工与风险水平相匹配的风险成本和收益。这家公司的员工在两个维度上是不同的：风险偏好和能力。我们的结果表明，工人为规避风险而支付费用的意愿是不同的。它可以达到他们预期净收益的40%，但平均只有1%。此外，配对对公司的好处相对较小：如果我们将注意力限制在可能配对的情况下，预计利润只会增加2.3%-4%。尽管劳动力市场分类对这一结果有贡献(该公司的工人相对具有风险承受能力)，但这并不是主要原因。更重要的是，该公司风险条件的相对同质性导致匹配机会有限。
We measure the cost of risk and the benefits of matching heterogeneous workers to risk levels within a firm that pays its workers piece rates. The workers of this firm are heterogeneous in two dimensions: risk preferences and ability. Our results suggest that workers' willingness to pay to avoid risk is heterogeneous. It can attain 40% of their expected net earnings but averages to only 1%. Moreover, the benefits to the firm of matching are relatively small: profits are predicted to increase by only 2.3%, 4% if we restrict attention to cases where matching is possible. Although labor-market sorting contributes to this result (the workers in this firm are relatively risk tolerant), it is not the primary cause. More important is the relative homogeneity of risk conditions in this firm that give rise to limited opportunities for matching.
