The Supply for Pecans

The following are fictitious headlines about the pecan market. In each case decide if the information will cause a change in the current market supply for U.S. Pecans sold worldwide.

2. The price of pecan shelling machines rises dramatically.

3. Price of pecans falls as more consumers begin craving hazelnuts.

4. Scientists successfully produce genetically modified pecan trees that can produce twice as many pecans per tree.
