The Production Function in the Romer Model Is Given by ________

The production function in the Romer model is given by ________, where $\bar g$ is ________.

A) $y _ { t } = A _ { t } k _ { t } ^ { 1 / 3 }$ ; the growth rate of capital
B) $y = \bar { A } _ { 0 } ( 1 + \bar { g } ) ^ { t }$ ; the growth rate of knowledge
C) $y = \bar { A } _ { 0 } ( 1 - \bar { \ell } )$ ; the growth rate of population
D) $y = \bar { A } _ { 0 } ( 1 - \bar { \ell } ) ( 1 + \bar { g } ) ^ { t }$ ; the growth rate of knowledge
E) $y = \bar { A } _ { 0 } ( 1 - \bar { \ell } ) ^ { t }$ ; the growth rate of population
