Recently, Crespi and Chen (2019) reported on the comparative advantage of the United States relative to its major export competitors in the markets for beef, pork, corn, and soybeans. This policy brief provides the same exposition for the world wheat markets. (For details on the analysis, readers are referred to Crespi and Chen 2019). Crespi and Chen (2019) showed that increasing total U.S. export values for the four commodities of their study masked an underlying slippage in comparative advantage and, because of this, 2018 was “a bad time to start a trade war.”
