The United States is a major player in global agricultural markets. American farmers account for around 25 percent of world exports of wheat and corn, and are also among the largest producers and exporters of beef, pork, and poultry. This success is partly the result of those farmers having access to abundant land, deep financial markets, and modern technologies. But as I explore in my new book, Global Agriculture and the American Farmer: Opportunities for U.S. Leadership, it is also the result of government policies that distort markets and undermine the provision of global public goods. The poor in developing countries are particularly vulnerable to the negative spillovers of these policies.
