Source: Author's analysis based on data described in text. Notes: Table provides descriptive statistics on intensive-margin sample. An included observation is the first-difference of values for an exporter-importer-industry-period from the prior period. For the differencing, the exporter's labor productivity at the industry level must be reported in the UNIDO database in both periods and the export volumes in the World Trade Flows database must exceed $100k for both periods. All trade with the United States is excluded. Column 2 reports the number of periods after first differencing that a country is included in, and the third column provides route-level observation counts after first differencing. Columns 4 and 5 provide labor productivity estimates from the UNIDO database. Columns 6-8 report statistics from the World Trade Flows database, with volumes expressed in US dollars. The last two columns document the two largest ethnic heritage cities used in the instrument design. Cities are defined at the consolidated metropolitan area level, with abbreviated names provided.
