Pre-print, Working paper: Activists monitoring global value chains are closely linked to international production and sales by companies. Academic research on international trade is however scarce in empirical work analyzing the behavior of these activists. The Sigwatch campaign database is a new and rich dataset listing campaigns launched by activists against multinational corporations. I provide explanatory notes on the raw data available for academics, and background information on the replication dataset for Hatte and Koenig (2017). Short descriptive statistics on campaigns are also presented.
