Document Summary

Economic growth, an increase in the productive capacity of the economy. Potential gdp: the productive capacity of the economy, gdp if all factories and workers and economy as a whole were working full-time. It is possible for real gdp to exceed potential gdp (working overtime) When real gdp exceeds potential gdp there is an inflationary or expansionary gap: when real gdp is below potential gdp there is a recessionary gap. When real gdp=potential gdp the economy is in long-run equilibrium. Economic growth is an increase in the potential gdp. Most economic policy is aimed at softening the business cycle, lessening peaks and raising troughs to more closely match the potential gdp. Real gdp per capita is gdp for that year divided by the population in that year: real gdp per capita growth rate is approximately equal to real gdp growth rate minus population growth rate.
