In reading Jerry Hagstrom’s report on a 3-day conference, Agriculture Investment Summit for the Americas, we were struck by the witty insight of Jason Henderson when he said, “I have never met a farmer who is unwilling to produce himself [or herself] out of prosperity.”

In that one sentence, Henderson, executive vice president of the Omaha branch of the Federal Reserve Bank of Kansas City, summed up what agricultural economists have long known. Historically, the production of agricultural crops, sooner or later, outruns demand, resulting in multi-year periods of low prices. The same is true in the shorter-run for livestock, although producers there adjust production much more quickly than crop producers resulting in what have historically been hog and cattle cycles.

This tendency towards over-production is not a new phenomenon in U.S. agriculture. Shortly after the settlement of the first colonists in North America, farmers began to ship a new-fangled product called tobacco to London. Smoking caught on like wildfire—so to speak—and the production of tobacco became very lucrative.

The price was so lucrative that others quickly began to produce so much tobacco that within 40 years they had flooded the market. Prices fell so dramatically that several colonies were looking at acreage restrictions on the planting of tobacco in order to boost prices to a profitable level.

For a time, production of indigo in the U.S. South was profitable, but with increased production in the U.S., Central America, and South America, along with the advent of the Revolutionary War and the loss of the British per pound bonus, U.S. producers could no longer compete and the domestic market collapsed, never to recover.

The pattern of profitable prices, followed by increased production and the addition of new production areas, resulting in long troughs of low prices has plagued  producers of corn, cotton, and wheat through much of U.S. history, particularly following the Civil War and opening up of the Great Plains to crop agriculture. In the last century, this pattern was repeated following WWI, WWII, and the export boom of the 1970s.

We are now experiencing a similar boom and at the investing summit, Gerald Bange, Chair of USDA’s World Agricultural Outlook Board, told his audience: “We’re not going to see $2 and $3 corn again in the” U.S. Much of his optimism is based on ethanol production and a growing export demand.
