Technically speaking, in what year did the "Great Recession" end?

Economic progress is best measured by

a. the growth rate of prices over time. b. the growth rate of GDP per capita c. the amount of time it takes a worker to work to afford certain goods and services. d. the growth rate in the population.

Why does inflation make nominal GDP a poor measure of the increase in total production from one year to the next?

What will be an ideal response?
