Shows explained differences in fresh products from Oaxaca-Blinder regressions with robust standard errors and asymptotically normal Z tests. The coefficient is the difference in each nutrient content per dollar between developed and developing countries explained by the product characteristic. Dev 1 divides Gross Domestic Product Per Capita in Purchasing Power Parity (GDPPCPPP) into quintiles, and it assigns the bottom two quintiles to developing and the top three quintiles to developed; Dev 2 uses country-level GDPPCPPP and assigns the bottom two quintiles to developing, the top two quintiles to developed, and drops the middle quintile; Dev 3 divides the United Nations Human Development Index (HDI) into quartiles, assigns the first and second quartiles to developing and the third and fourth quartiles to developed; and Dev 4 uses the UN FAO’s Low Income Food Deficit Country (LIFDC) list to assign developing, and countries not listed are considered developed; Dev 5 assigns a country to developing if the World Bank GNI indicator is in the bottom two groups (low or lower-middle income) and assigns all others to developed; Dev 6 assigns a country to developing if the World Bank GNI indicator is in the bottom group (low income), assigns the country to developed if it is in the top group (high income), and drops the other countries from the sample. The base category for preservation is frozen and whole.
