Final answer:
If workers immigrate from Canada to Minnesota, the equilibrium wage would decrease and the quantity of labor would increase.
Step-by-step explanation:
In the market for labor in Minnesota, if workers immigrate from Canada, the equilibrium wage would decrease, and the quantity of labor would increase. With more workers, the added output from an extra worker is smaller.
The demand for labor would increase due to the additional workers, which would initially lower the equilibrium wage. However, the increase in the quantity of labor would also lead to a decrease in the added output from an extra worker, resulting in a smaller decrease in the equilibrium wage.
