In Exhibit 2-15, evidence of the law of increasing opportunity costs is:
To get the first 10 capital goods, the economy has to give up 2 consumption goods. But to get the next 10 capital goods, the economy has to give up 8 consumption goods. The downward slope of the production possibilities curve shows that the amount of capital goods increases by 10 units as the economy moves from point I to point K to point L to point M to point N.
On the other hand, the amount of capital goods increases by 10 units as the economy moves from point L to point G.
