Question 76

In the combined Solow-Romer model, the growth rate of total output, using the production function $Y _ { t } = A _ { t } K _ { t } ^ { a } L _ { y t } ^ { 1 - a }$ is given as:

A) $g _ { Y } = g _ { A } + a g _ { K }$
B) $g _ { Y } = g _ { A }$
C) $g _ { Y } = g _ { A } + a g _ { K } + ( 1 - a ) g _ { L Y }$
D) $g _ { Y } = g _ { A } + g _ { K } + g _ { L Y }$
E) $g _ { Y } = g _ { A } \times a g _ { K } \times ( 1 - a ) g _ { L Y }$

Question 77

C) an increase in the research share increases the growth rate in the short and long runs
D) a decrease in the research share increases the growth rate in the short run
E) There are no level effects.

Question 78

In the growth accounting equation,
$g _ { y } = \underbrace { ( 1 / 3 ) \left( g _ { K } - g _ { L } \right) } _ { A } + \underbrace { ( 2 / 3 ) g _ {L Y } } _ { B } + \underbrace { g _ { A } } _ { C }$ , A represents ________, while B is called ________.

A) labor composition; capital accumulation

C) the contribution from capital; labor composition
D) educational attainment; labor composition
E) per capita capital contribution; labor composition
