Data and Code for: Noise, Cognitive Function, and Worker Productivity

This is the data and code needed to replicate the results in Noise, Cognitive Function, and Worker Productivity.

Paper Abstract:
Cognitive science research suggests the noisy workplaces common in low and middle income countries can impair workers’ cognitive functions. However, whether this translates into lower earnings for workers depends on the importance of these functions for productivity and whether workers understand these effects. I use two randomized experiments in Nairobi, Kenya to answer these questions. First, I randomize exposure to engine noise during a textile training course at a government training facility. An increase of 7 dB reduces productivity by approximately 3%. In order to study what mechanism drives this effect, I then randomize engine noise during tests of cognitive function and an effort task. The same noise change impairs cognitive function but not effort task performance. Finally, in both experiments, I examine whether individuals appreciate the impact of noise on their performance by eliciting participants’ willingness to pay for quiet working conditions while randomly varying whether they are compensated based on their performance. Individuals’ willingness to pay does not depend on the wage structure; suggesting that they are not aware that quiet working conditions would increase their performance pay. Thus, workers may fail to mitigate earnings losses by sorting into quieter jobs where they are more productive.
