Since the PV of labor income is $60, and $60 = $40 + $22/(1 + r), r must be equal to 10%. NPV = $75 – $60 = $15 Her wealth is $75. Letting C denote consumption, she wants $75 = C + C/(1 + r) where r = 0.10. Solve for C; C = $39.29.

4A.5

a. b. c.

$90,000/$80,000 – 1 = 0.125 = 12.5% Harry will invest $10,000 in financial assets and $30,000 in productive assets today. NPV = –$30,000 + $56,250/1.125 = $20,000
