Pine trees can take about 30 years to grow. A number of family farmers in southern states like Mississippi converted their land from growing other crops to growing pine trees. One farmer was quoted as saying, “We thought the future was pine trees.” In 2018, demand for housing resulted in strong demand for lumber made from pine. Yet prices of lumber were falling, and one industry observer was quoted as saying, “It’s unclear we’ll ever have timber prices like we did 10 or 20 years ago.” The farmer who thought that the future was in pine trees found that he could sell them for only $14 per ton rather than the $45 per ton he had expected when he planted them decades before. Use a demand and supply graph to explain how it is possible that despite strong demand for lumber to be used in housing, prices for pine trees were much lower than many farmers had expected when they planted the trees.
