Problem 3

Based on Roberts and Schlenker (forthcoming), the corn demand elasticity is $\varepsilon=-0.3,$ and the supply elasticity is $\eta=0.15 .$ According to the 2007 Census of Agriculture, the United States has 347,760 corn farms. Assuming that the farms are of roughly equal size, what is the elasticity of demand facing a single farm? (Hint: See Solved Problem 8.1.)
