Continue…. “The house holds maximizing the utility will so allocate the expenditure between commodities that the utility of the last Rupee spent on each item is equal.” Formula for Consumer’s equilibrium… MUA/PA = MUB/PB = ….= MUN/PN

Continue…. Assumptions: Utilities are independent Marginal utility of money remains constant. Utility is cardinal. Consumer is rational.

Explanation We assume that: The consumer has Rs.5 with him. He has to spend his income on two goods A and B. The price of each good is Rs.1 per unit.

Table… Units of money MU of A MU of B 1 12 10 2 8 3 6 4 5 Total 39 30

Limitations.. Utility is immeasurable. Indivisible goods Prices and tastes are changing. Time Factor.
