The effect of GitHub Copilot on the task composition of jobs among management consultants: evidence from a randomised controlled trial

[SYNTHETIC full text — teaching stand-in for an open-access PDF.]

1. Introduction
This paper studies the labour-market impact of the technology described in the
title. We study how the adoption of GitHub Copilot affects the task composition of jobs among management consultants. Using a randomised controlled trial covering the 2022–2023 period, we estimate the impact of access to GitHub Copilot on the outcome of interest. We find no statistically significant change. The results are robust to alternative specifications and are concentrated among less-experienced workers. We discuss implications for how GitHub Copilot reshapes the tasks and skills that make up these jobs.

3. Data and design
Design: RCT. The sample is drawn from administrative and survey
sources over the study window. Table 3 reports the main estimate.

4. Results
Main estimate (Table 3, column 4): the point estimate is 0.053
(standard error 0.081) [SEE PAGE 7]. Effect class:
null. Heterogeneity analysis on page 9 shows the effect concentrates
among less-experienced workers.

6. Conclusion
We discuss how the technology reshapes the tasks and skills composing these jobs.
