Question 19 (3 points) Saved Assume that a Cobb-Douglas production function is a good representation of the economy, the substitution effect is stronger than the income effect, the real wage is flexible, and that the economy was initially at equilibrium. Suppose that an earthquake hits the economy, destroying a large number of homes and manufacturing factories (including machines within the factories) but not causing any deaths or injuries in the population. If the real wage is completely flexible, what will happen to the marginal productivity of labor? There would be no change in the marginal productivity of labor There would be an increase in the marginal productivity of labor There is not enough information to determine if a change in the marginal productivity of labor would occur. There would be a decrease in the marginal productivity of labor
