Although New York State is second only to Washington State in production of apples, its production has been declining during the past 20 years. The decline has been particularly steep in counties close to New York City. In 1985, there were more than 11,000 acres of apple orchards in Ulster County, which is 75 miles north of New York City. Today, only about 6,000 acres remain.

As it became difficult for apple growers in the county to compete with lower-cost producers elsewhere, the resources these entrepreneurs were using to produce apples - particularly land - become more valuable in other uses. Many farmers sold their land to housing developers.

Suppose a nutritionist develops a revolutionary new diet that involves eating 10 apples per day.

The new diet becomes wildly popular. What effect is the new diet likely to have on the number of apple orchards within 100 miles of New York City? What effect is the diet likely to have on housing prices in Ulster County
