Explain in short note please

. lI'Sonsider two closed economies that have the same real interest rate. If consump- tion growth is higher and less volatile in Economy.r A. relative to Econorny B. what implications does this have for preferences in the ham economies? . 0n: ot'the stylized facts ofgrowth is a growing wage rate and a {relatively} constant labor supply. What restrictions does th'n place on agents\" preferences? . In the Solow model, what happens when there is a permanent increase in the savings rate? Describe both the transition and steady-state effects. What economic forces are at work?' . An equity is a claim to a stream of future dividends Suppose that dividends grow at a constant rate 3 and are discounted at a constant rate r, with r :- 3. There is no uncertainty. The price of the equity is the present discounted value of this dividend stream. What is the price-dividend ratio? (Hint: 1 would do this in continuous time, but you don't have to_} . Re question (4}, what happens to the price-dividend ratio when there is a permanent increase in r'? How about when there is a permanent increase in 3? Briey provide economic intuition for each. 8. Consider an exchange cash-in-advance economy similiar to that studied by Alan Stockman in which the money supply, Mr, grows at the (gross) constant rate # > 0 so that My = #M,-1. The endowment in this economy is stochastic and can take on two values (x1, *2) with x1
