TRUE/FALSE

1. The standard of living of people in a country is their per capita income.

2. Diminishing returns to labor implies that eventually the marginal product of labor will become

negative.

3. The marginal product of capital is how much output changes when capital increases by one unit.

4. Saving is income that is not consumed.

5. Real saving equals gross investment.
