(group) The summer of 1988 saw a record-breaking drought in the agricultural heartland of the United States. The following year saw the largest jump in U.S. crop acreage since World War II. What prompted farmers to undertake such a public-spirited response to the situation created by the drought?
They could make more money. If the drought went on for a second year, the farmers who do have goods to sell will see higher demand. Even if it did not, there might still be higher demand based on the previous year's scarcity.
