Consider the Ricardian Corn Model. Suppose all grades of land experience the same absolute increase in their productuivity. With the help of a diagram, explain what Ricaedian analysis predicts will be the immediate impacts of the shock on rents, profit, wage and the size of the labor force. With the help of another diagram, explain what Ricardian analysis predicts will be the long run impacts of the shock on rents, profits, wage and the size of the labor force.
