Some software projects:

• ivcombine function in Stata for IV estimation with multiple instruments under a relaxed monotonicity assumption
  • This is a work in progress, accompanying the paper: A Vector Monotonicity Assumption for Multiple Instruments.
  • [Download from GitHub]
• rdbounds function (Stata and R) for bounds in regression discontinuity designs allowing for manipulation
  • This is work with François Gerard, Miikka Rokkanen & Christoph Rothe, to implement the estimator proposed in their paper: Bounds on Treatment Effects in Regression Discontinuity Designs with a Manipulated Running Variable.
  • [Download from GitHub]
• Forest Conservation Targeting Tool
  • This is work with Allen Blackman, Jessica Chu, and Juha Siikamäki, and the SERVIR project. It was one of my projects while a Research Assistant at Resources for the Future.
