Question 2 (Wall-E) In the 29th century, the Earth has become uninhabitable, and humans have left it, living in spaceships that orbit around the planet. They have become unable to work due to their laziness, microgravity, and prolonged time in front of computers. Everything is hence produced by machines and robots: the production function is Y = AK. Apart from this weird production function, the economy is well described by the Solow growth model. There is a constant saving rate 3, and a constant depreciation rate (1. Population is constant, and so is total factor productivity A. The capital accumulation follows Kt\" = Kt + If _ th. a. Calculate the growth rate of capital per person. b. What is the steady state for capital per person? Explain. c. What does this suggest for the economic growth in the long run? Can you calculate the growth rate of output per person? What happens if we increase 5? d. What do you think is the reason behind the results in a-c? Discuss
