Thanks, Chris. You're right that Pacific means the West Coast (the analog to NEUDC's "Northeastern"). Your comment reminds me of Das et al's 2013 JDE paper "U.S. and Them: The Geography of Academic Research", which looks at how much economic research is published on different countries. They find, both globally and within regions, a stark positive correlation between GDP and research carried out (controlling for population). On average, there seems to be slightly less research on Africa than on East Asia & the Pacific together, but the East Asia average is pulled up by China, Indonesia, etc., so the Pacific may be not very well represented.
