You live in country “I-love-spring-and-gosh-I-wish-I-could-go-outside-now” (ILSAG, for short). ILSAG has a Cobb Douglass production function Y=K 1/2 L 1/2 . The hard- working citizens of ILSAG save 20% of their incomes and the depreciation rate in the economy is 10%. a. According to the Solow model, what should be the steady-state level of capital per worker? b. What would be the “golden rule” level of capital per worker? c. What savings rate would give rise to the golden rule level of capital? d. Suppose you are the almighty ruler of ILSAG and your dutiful citizens do everything you tell them. If you care only about your citizens long-run happiness (read: consumption) what fraction of their savings should you have your citizens save? e. Given your last answer, suppose that you tell your people to switch their initial savings rate from what it was initially to the rate that would make them happiest in the long-run. What will be the dynamics of the capital stock in the short run?
