Suppose you add a variable rate of population growth to a two-sector model of growth. Draw and properly label a graph on how the production function, investment requirement line, and saving line look like. Does the addition of the variable rate of population growth to this model help you explain anything that a simpler two-sector model with a fixed rate of growth, or a one sector model with variable population growth, cannot? Expound.

Assume positive population growth ( n > 0) and technological progress ( g > 0 ). Derive analytically the steady-state growth rates of output and capital, and the steady-state levels of output and capital per efficiency unit of labour. Illustrate your answer graphically and briefly discuss the economic intuition.

11. In 2022 a country has the following data: GDP TFP Capital Labor Y A K L 400 1,100 20 The production function is Y = A¿KQ4 LQ.6 and the capital stock evolves according to Kt+1 growth rate of labor is 0.6% and TFP growth is 2%. Assume that population is equal to labor. Use the Solow model to calculate per-capita GDP in 2024 (two years later). (1 – d)Kt + It. The saving rate 22%, the depreciation rate is 10%, the (а) 498.32 (b) 504.42 (c) 516.96 (Right answer) (d) 548.87

Which of the following are true of capital as a determinant of economic growth? Check all that apply. Capital investment decreases per capita real GDP. Technological advances allow more output from the same amount of capital. As consumption increases, capital formation also increases. Countries with higher investment rates tend to have higher growth rates.
