Urban Economics 8
Consider the effects of a natural disaster like hurricane Katrina on a metropolitan economy. In the initial (pre hurricane) equilibrium, total employment in the metropolitan area is 500,000 workers and the daily wage is $100. The price elasticity of supply of labor is 4.0 and the price elasticity of
