Question 2 Assume an economy's aggregate production function has the following form Y = AK³L¹-* Where a = 0.25 and where output Y is produced using capital K and labour L, and A is total factor productivity. The population growth rate n is 1.5% per year. The depre- ciation rate of capital is 10%. Total factor productivity equals 20 i.e. A = 20 and we assume the growth rate of A is zero. a) Show that the production function displays constant returns to scale. b) Show that the production function displays diminishing returns to capital. c) If the country's savings rates is 20%, find its steady state capital stock per capita, income per capita, consumption per capita, and investment per capita. d) What is the optimal i.e. Golden Rule capital stock per capita in this economy in steady state? Is this economy dynamically efficient? Explain your answer.

estion 30 A country with neither population growth nor technological progress is nitaly in the golden-rule steady state. Carefuly ilustrate this situation using a graph with output per worker, investment per worker, and depreciation per worker on the vertical axis and capital per worker on the horizontal axis. Now suppose climate change increases the depreciation rate. If the country adjusts its saving rate to reach the new golden- rule steady state, is it possible to determine how output per worker and consumption per worker in the new steady state compare to their levels in the initial steady state? Explain.
