Juanita: I think it's safe to say that, in general, the savings rate of households in today's economy is much lower than it really needs to be to sustain an improvement in living standards. Gilberto: I think a switch from the income tax to a consumption tax would bring growth in living standards. Juanita: You really think households would change their saving behavior enough in response to this to make a difference

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.)
