- Work for me this summer: I’m a bit late in organizing this sorry, but I have an opportunity for a summer research assistant to work with me in Washington. Looking for a PhD student from a top school with good Stata skills, and ability to do careful data work. If you have studied machine learning this would be a plus. There are several potential projects to work on: one on using machine learning to help predict which small businesses will grow; a second on understanding how small business owners use mental accounting techniques; as well as work helping clean and prepare public use replication files for several papers. Email me (dmckenzie@worldbank.org) if interested with your CV and a cover letter explaining your background and experience/suitability. I’m flexible on starting and ending date to fit different university calendars. A TOR is here.
