Economics MCQ - Economics Section 1
Output growth is equal to the growth rate of labor force plus the growth
rate of labor productivity i.e. output per worker. Unlike total factor
productivity, output per worker is observable, so this is the most
practical way to approach estimation of sustainable growth rate.
In the standard Solow growth accounting equation, the coefficient on
each factor’s growth rate is its share of income.
