Cоnsider а lоcаl lаbоr market.  Say that the relationship between the wage and the quantity of workers supplied is given by the equation q0S = 40 + [a]w, and the quantity of workers demanded is given by the equation q0D = 400 - w. First solve for the equilibrium wage, w0*, and the equilibrium number of workers employed, q0*. Now imagine that immigration quotas are lifted, so that an influx of foreign workers enter the labor market.  Does this shift labor supply or demand?  If supply shifts outward, add +60 to q0S to get q1S.  If supply shifts inward, instead subtract -60 from q0S to get q1S.  If demand shifts outward, add +60 to q0D to get q1D.  If demand shifts inward, instead subtract -60 from q0D to get q1D. Solve for the new equilibrium wage, w1*, and the equilibrium number of workers employed, q1*.  If 60 of these workers are foreign, the rest are domestic.  What is the change in the number of domestic workers employed before and after immigration?  Subtract q0* from q1* - 60 and provide that number here.  If your number is negative, include a leading hyphen.
