Consider these three bonds: 1) ustn 10% due 3/31/2025 with a yield to maturity of 3.5% 2) ustn 3% due 3/31/2025 with a yield to maturity of 3.6% 3) ustn 10% due 12/31/18 with a yield to maturity of 3.1% which bond has the highest risk and which bond has the lowest risk. tell me in your own words, what bond risk means to you. if you were investing in bonds and you believe interest rates will rise across the entire yield curve, which of these three bonds would you buy and why.

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.)
