James Gerber, professor emeritus of economics at San Diego State University, and Eduardo Mendoza, professor in the Department of Economic Studies at El Colegio de la Frontera Norte, discuss the challenges in making comparisons between sub-national units across the U.S.-Mexico border with existing data. They offer recommendations for future data collection efforts to help answer questions about economic and social integration at the border region. Their research can be found in the edited volume "Binational Commons" available at Amazon.
