For most papers I am implementing a new method, adapting an old one or implementing other econometrically interesting things. My plan is to eventually post the most exciting bits either as code-snippets, fully-fledged Stata programs, or R functions under the heading “Data & Code”. There you can also find the data sets used in my published papers.
