Macroeconomics Questions?

Can anyone help with these? (no, they are not homework questions... they are questions that I missed on a test and would like to know what the answers are so I can study for the next test)

1. Output per person increases only when _______ grows faster than population. (it is not nominal GDP)

2. The net addition to our nation's capital stock is the difference between...
(it is not saving and gross private domestic investment)

3. An economy that is in equilibrium will be producing at a level of output equal to ...
(it is not potential GDP)


Thanks for any help you may have.

Answer:
1.output-because that means that each person is producing more and the overall increase in production isnt a result of population growth.

2.investment and depreciation-because depreciation is what is taken away from your capital stock and investment is what is added according to the solow growth model which im assuming is what your teacher based your question on

3. the level of demand-because its not asking you for the optimum point of production but for the equilibrium point and equilibrium is always forme when supply equals demand.

try getting macroeconomics by burda and wyplosz its a very good book if you are generally into macro.
1. Demand - as only than the producction will have to be increased;
2. New addition/arrivals and depreciation.
3. Demand
