Investigate how demand elastiticities are affected by increases in demand. Shift each of the demand curves in Figures6.2a, 6.2b, and 6.2c to the right by 10 units. For example, point a in Figure6.2a would shift rightward from location (10 units, $2) to (20 units, $2), while point b would shift rightward from location (40 units, $1) to (50 units, $1). After making these shifts, apply the midpoint formula to calculate the demand elasticities for the shifted points. Are they larger or smaller than the elasticities you calculated in problem 1 for the original points? In terms of the midpoint formula, what explains the change in elasticities?
