Consider a world consisting of two countries, Ghana and Canada. Suppose the domestic demand and-supply curves for bicycle in Ghana are given by the following equations: Demand: P = 80 - 2Q

Supply: P =5 + 3Q

Several years after, Ghana enacted a law stating that imports from Canada should be reduced to zero. What will be the domestic price of bicycles? What is the net national welfare cost/benefit of this policy using (iv) as the reference point?
