The Gravity Cookbook website
This site provides material referred to our Handbook of International Economics (HIE) chapter:
Keith Head and Thierry Mayer, 2014, Gravity Equations: Workhorse,Toolkit, and Cookbook, Chapter 3 in Handbook of International Economics, Editor(s): Gita Gopinath, Elhanan Helpman, Kenneth Rogoff, Elsevier, Volume 4, Pages 131-195.
This research has received funding from the European Research Council under the European Community’s Seventh Framework Programme (FP7/2007-2013) Grant Agreement no. 313522 (HETMAT).
The website also provides additional resources for researchers who estimate gravity equations, in particular links and codebook for gravity-relevant datasets (including the CEPII gravity dataset) and stata programs used in our chapter.
NEW: We also provide here the replication package for our paper
Head, K. and T. Mayer, 2021, "The United States of Europe: A gravity model evaluation of the four freedoms", Journal of Economic Perspectives 35(2): 23-48. Online appendix.
The archive contains updated code and data for gravity estimation (mostly in R)
