Gravity dataset without zero trade flows — gravity

An edited version of the full gravity dataset: The "square" gravity dataset for all possible pairs of Countries worldwide, 1948-2006, which is used in the article: Head, K., T. Mayer and J. Ries, 2010, "The erosion of colonial linkages after independence". Journal of International Economics, 81(1):1-14 (lead article). Dataset gravity_no_zeros corresponds to the dataset without zero trade flows, gravity_zeros, on the other hand, includes zero trade flows.

Usage

data("gravity_zeros")

Format

A data frame with 22588 observations on the following 10 variables.

iso_o: ISO-Code of country of origin
iso_d: ISO-Code of country of destination
distw: weighted distance
gdp_o: GDP of country of origin in million dollars
gdp_d: GDP of country of destination in million dollars
rta: regional trade agreement dummy
flow: trade flow in million dollars
contig: contiguity dummy
comlang_off: common official language dummy
comcur: common currency dummy
