Suppose a region's workforce of 14 million is initially split equally between two cities, X and Y. The urban utility curve peaks at 4 million workers, and beyond that the slope is −$3 per million workers. The initial equilibrium utility level is $60. Suppose city X experieinces technological innovation that shifts its utility curve up by $12. 5.1 Draw a pair of utility curves, one for X and one for Y, and label the positions immediately after the innovation (before any migration) as X 0

for city X and Y 0

for city Y. Use arrows along the curves to indicate the migration that follows. 5.2 In the new equilibrium, the utility level of X is and the population of X is million, while the population of Y is
