Utility maximization with an initial endowment of goods Utility maximization with an initial endowment of goods Choose ( x 1 ; x 2 ) so that u ( x 1 ; x 2 ) is maximized under the constraints p 1 x 1 + p 2 x 2 p 1 ω 1 + p 2 ω 2 x 1 ± 0 x 2 ± 0. Interior Solution: MRS ( x 1 ; x 2 ) = p 1 p 2 p 1 x 1 + p 2 x 2 = p 1 ω 1 + p 2 ω 2 . Ani Guerdjikova ECON 313 Fall 2007 122 / 126

Utility maximization with an initial endowment of goods The O/er Curve O/er curve The o/er curve is the geometric place of all optimal consumption bundles x = ( x 1 ; x 2 ) of a household for di/erent relative prices p 1 p 2 . 1 At an interior solution MRS ( x 1 ; x 2 ) = p 1 p 2 p 1 x 1 + p 2 x 2 = p 1 ω 1 + p 2 ω 2 . 2 Substituting for p 1 p 2 , we obtain the equation of the o/er curve: x 2 = MRS ( x 1 ; x 2 ) [ ω 1 x 1 ] + ω 2 .
