Suppose you start with $100 and buy stock for £50 when the exchange rate is £1 = $2. One year later, the stock rises to £60. You are happy with your 20 percent return on the stock, but when you sell the stock and exchange your £60 for dollars, you only get $45 since the pound has fallen to £1 = $0.75.

Suppose life expectancy in years (l) is a function of two inputs, health expenditures (h) and nutrition expenditures (n) in hundreds of dollars per year. the production function is upper l equals ch superscript 0.40 baseline upper n superscript 0.60l=ch0.40n0.60. beginning with c = 1, a health input of $400400 per year (hequals=44) and a nutrition input of $400400 per year (nequals=44), show that the marginal product of health expenditures and the marginal product of nutrition expenditures are both decreasing. the marginal product of health expenditures when h goes from 44 to 55 is nothing, and the marginal product of health when h goes from 66 to 77 is nothing. (round your answers to three decimal places.)
