中文摘要
低收入和中等收入国家常见的嘈杂工作场所可能损害劳动者的认知功能。然而，这是否会降低收入，取决于这些功能对生产率的重要性，以及劳动者是否理解这些影响。我通过在肯尼亚内罗毕开展的两项随机实验研究这些问题。我发现，噪声增加7分贝使纺织培训课程中的生产率降低3%，损害认知功能，但不影响努力程度。我还发现，对安静工作条件的支付意愿并不取决于报酬是否与绩效挂钩，这表明参与者并未意识到安静会提高其生产率。（JEL D12, J24, J28, J31, J81, O15, Q53）
Abstract
Noisy workplaces common in low- and middle-income countries can impair workers' cognitive functions. However, whether this lowers earnings depends on the importance of these functions for productivity and whether workers understand these effects. I study these questions with two randomized experiments in Nairobi, Kenya. I find a noise increase of 7 dB reduces productivity in a textile training course by 3 percent, impairs cognitive function, but does not affect effort. I also find willingness to pay for quiet working conditions does not depend on whether pay depends on performance, suggesting participants are not aware that quiet would increase their productivity.
