Let a consumer's preferences are reflected by a Cobb-Douglas utility function i.e., UXLX) = Xf x5 BM X2 P2 αM The demand functions derived from this utility function are: P1 Where, M is the income level, Pi and P2 are respective prices. g and B are respective shares of X1 and X2, and at+B=1 Calculate and prove the following: For good Xı, sum of all price and income elasticities is equal to zero. Weighted sum of all income elasticities is equal to one. Weighted sum of all price elasticities with respective to the price of one good is negative.

The demand functions derived from this utility function are:
P1
Where, M is the income level, P1 and P2 are respective prices. a and B are respective shares of
X1 and X2, and a+B=1
Calculate and prove the following:
• For good X1, sum of all price and income elasticities is equal to zero.
• Weighted sum of all income elasticities is equal to one.
Weighted sum of all price elasticities with respective to the price of one good is
negative.
