II. Neoclassical growth theory primarily examines the effects of productivity growth on economic growth.
III. Under the neoclassical growth theory, the long run steady state equilibrium is achieved when the growth rates of capital per capita and income per capita are constant.
IV. According to the neoclassical theory of growth, long run economic growth is dependent upon the savings rate of a nation.

Correct Answer: I and III

II is incorrect because the neoclassical growth theory primarily examines the effects of savings choices on capital growth.
