The Impact of AI on Developer Productivity: Evidence from GitHub Copilot
Sida Peng, Eirini Kalliamvakou, Peter Cihon +1
Generative AI tools hold promise to increase human productivity. This paper presents results from a controlled experiment with GitHub Copilot, an AI pair programmer. Recruited soft…
Communication network dynamics in a large organizational hierarchy
Nathaniel Josephs, Sida Peng, Forrest W. Crawford
Most businesses impose a supervisory hierarchy on employees to facilitate management, decision-making, and collaboration, yet routine inter-employee communication patterns within w…
Doubly Robust Semiparametric Difference-in-Differences Estimators with High-Dimensional Data
Yang Ning, Sida Peng, Jing Tao
This paper proposes a doubly robust two-stage semiparametric difference-in-difference estimator for estimating heterogeneous treatment effects with high-dimensional data. Our new e…
Regression Discontinuity Design under Self-selection
Sida Peng, Yang Ning
In Regression Discontinuity (RD) design, self-selection leads to different distributions of covariates on two sides of the policy intervention, which essentially violates the conti…
Heterogeneous Endogenous Effects in Networks
Sida Peng
This paper proposes a new method to identify leaders and followers in a network. Prior works use spatial autoregression models (SARs) which implicitly assume that each individual i…
Robust Estimation of Causal Effects via High-Dimensional Covariate Balancing Propensity Score
Yang Ning, Sida Peng, Kosuke Imai
In this paper, we propose a robust method to estimate the average treatment effects in observational studies when the number of potential confounders is possibly much greater than…
