-adjusted price of agricultural commodities fell consistently and considerably during the 1980s and 1990s. For example, in constant US dollars, the global farm price of soybeans fell by 29 per cent from 1980 to 2002, and the global farm price for corn fell by 21 per cent. Meanwhile, enhanced agricultural trade has allowed the US food supply to better respond to supply shocks, which are most often the result of severe weather events, globally or domestically.
