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 an increase in noise of 7 dB reduces productivity in a textile training course by 3%, 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.
