Unformatted text preview: countries two industries • Factors will receive the same payments across industries. 5 Indifference Curves cannot cross 6 C Example • U=C*T; C=20, T=5; so C,T=20,5 • U=20*5 = 100 • Everywhere on this indifference curve, U=100 • Another point would be C,T = 4,25 and C,T=5,20 • What is the slope between C=4 and C=5? – If C=4 then T=25 and if C=5, T=20 • (25-20)/(4-5) = -5/1 = -5 • Slope between C=19 and C=20? – At C=19, T = (100/19)=5.26 7 Budget Constraint (line) • P c C + P t T = M – M is income • Solve for T (vertical axis) • P t T= M - P c C • T = M/ P t - (P c /P t ) C • Slope – relative price of C! 8 Autarky: Constant Op.
