Figure 3 12. a. Farmers whose crops weren't destroyed benefited because the destruction of some of the crops reduced the supply, causing the equilibrium price to rise. b. To tell whether farmers as a group were hurt or helped by the floods, you'd need to know the price elasticity of demand. It could be that the additional income earned by farmers whose crops weren't destroyed rose more because of the higher prices than farmers whose crops were destroyed, if demand is inelastic. 13. A worldwide drought could increase the total revenue of farmers if the price elasticity of demand for grain is inelastic. The drought reduces the supply of grain, but if demand is inelastic, the reduction of supply causes a large increase in price. Total farm revenue would rise as a result. If there's only a drought in Kansas, Kansas’ production isn't a large enough proportion of the total farm product to have much impact on the price. As a result, price does not change (or changes by only a slight amount), while the output of Kansas farmers declines, thus reducing their income. 14. When productivity increases for all farmland at a point in time, the increased productivity leads to a rise in farmland prices, since more output can be produced on a given amount of land. But prior to the technological improvements, the productivity of farmland depended mainly on the prevailing weather conditions. There was little opportunity to substitute land with worse weather conditions for land with better weather conditions. As technology improved over time, it became much easier to substitute one type of land for another. So the price elasticity of supply for farmland increased over time, since now land with bad weather is a better substitute for land with good weather. The increased supply of land reduced farmland prices. As a result, productivity and farmland prices are 44

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
