3Actual and Potential GDP in USA
Potential GDP growth rate during post war period
4Actual and Potential GDP in the US
- Data show actual GDP fluctuates up and down
around potential GDP. Thus, long term economic
growth rate (_____________________________________
________) is roughly the same as the potential
GDP growth rate.
The average economic growth rate over a long
period
- An objective of macroeconomic policy is to have
__________________________________.
high potential GDP growth rate
5What do we learn from the experiment?
technology
- The higher the growth rate of ___________,
_________, ____________, or ________________, the
higher the growth rate of potential GDP - Higher ________________ growth is however not
desirable because the higher it is, the lower the
growth rate of _____________.
capital
human capital
labor (population)
labor (population)
