Alberto's utility function is u(xA, YA) = min{A, YA}, where
consumptions of goods and y. Bella's utility function is u(XB, YB)
where x³ and yß are her consumptions of goods and y. Alberto's endowment
is 5 units of x and no y. Bella's endowment is 11 units of y and no x. If x is the
numeraire and p is the price of y in units of x, then in a competitive equilibrium
○ 11/5 = p
11/(p+1) +2.5 = 11
O min{5, 11}+11/2p=11
O min{5, 11}+5/2p=11
○ 5/(p+1) +5.5 = 11
