Nоte: sаme infоrmаtiоn for questions 20-25, except where otherwise noted. A smаll country is engaged in free international trade with a large country. There are two sectors (goods): sector (good) x and sector (good) y. There are three factors of production: labor, which is perfectly mobile across the two sectors; land, which is specific to good x; and capital, which is specific to good y. The solid lines of the following figure represent: Px MPLx for the small country as a function of Lx, measured from origin O; and Py MPLy as a function of Ly, measured from origin O*. The length of the base of the figure is L=2000, the total units of labor in the country. One unit of labor is one worker working for a year. The scale on the vertical axis is thousands of dollars. Note that each grid spacing on the horizontal represents 50 workers, and each grid spacing on the vertical axis represents 1 thousand dollars. NOTES: - Ignore the dashed line until it is mentioned below. - Since this is a graphical question, some of the answers may be approximate! For all remaining questions in this group, suppose that labor can move freely from one sector to another. For the remainder of this group, suppose that the price of good y doubles, resulting in the dashed line, labeled P’y MPLy. When the price of good y doubles, the impact on workers is ______. To explain this, we need to understand that ______ .
