Note. Treatment Group 1 consists of three countries with epidemic transmission of 2014 Ebola: Guinea, Liberia, and Sierra Leone. Treatment Group 2 consists of three countries with limited cases of 2014 Ebola: Mali, Nigeria, and Senegal. The comparison group consists of 40 sub‐Saharan Africa countries without cases of 2014 Ebola. Estimates obtained from linear models with clustering by country and year. All models include controls for country‐specific time trends (not shown). Standard errors in parentheses. Models of U.S. exports are based on data for 2005–2016. Model of U.S. jobs is based on data for 2005–2015. U.S. exports in constant 2016 USD (millions).
