Unformatted text preview: You know what the demand function for X1 looks like. X1 = a/(a+b)*I/Px If you differentiate the above function w.r.t. own price, the other good s price and income respectively and multiply appropriate term according to the definition of eacy elasticity, you will get the following. (Sorry, it is very hard to write differentiation equations by MS word) Own price elasticity : 1 Cross price elasticity : 0 Income elasticity : 1 5. This is Quasilinear utility function. By MRS = ERS condition, we can derive a demand function for X. That is X = P y 2 / (4P x 2 ) There is no income effect in X, because there is no term such as income in the above equation. Therefore, Hicksian and Marshallian demand curve will be same. b CS = EV = CV...
