Any point inside the curve – suggests resources are not being utilised efficiently
Any point outside the curve – not attainable with the current level of resources

Production Possibility Frontiers
Assume a country can produce two types of goods with its resources – capital goods and consumer goods
If it devotes all resources to capital goods it could produce a maximum of Ym.
If it devotes all its resources to consumer goods it could produce a maximum of Xm
If the country is at point A on the PPF It can produce the combination of Yo capital goods and Xo consumer goods
If it reallocates its resources (moving round the PPF from A to B) it can produce more consumer goods but only at the expense of fewer capital goods. The opportunity cost of producing an extra Xo – X1 consumer goods is Yo – Y1 capital goods.
