resources residuals

Assume a concave production possibility curve. Suppose that society decides to increase the production of market goods by 10,000 units, and that as a result environmental quality falls by 10 units. If a further increase of 10,000 units of market goods is sought, we can expect that environmental quality will:

a) fall by 10 units.

b) fall by less than 10 units.

c) fall by more than 10 units.

d) increase by less than 10 units.
