Thus, as soon as we sign-up these types of factors P, Q and you may R, we get the new consult curve DD.
When it comes to Giffen Goods:
In the example of Giffen items, brand new consult bend very made from Rates Practices Bend is actually upward slanting. They represent the good dating ranging from price and you can quantity needed regarding a commodity.

Into the fig, X-axis suggests the amount of Giffen Item-step one recommended while Y-axis suggests the total amount of one other item-dos recommended. Here, Abdominal ‘s the new funds line and you will IC ‘s the modern Apathy contour. And you will, E ‘s the harmony area where finances range Ab is tangent to your IC curve. So far, an individual gets restrict satisfaction of the purchasing their earnings off Rs.900 ( Rs.750 for the ten systems from Giffen Item-1 and you will Rs.150 for the step three tools out-of commodity-2 ).
Suppose, the price of Giffen Commodity-1 falls down to Rs.50 from Rs.75. As a result, the budget line shifts to AC and indifference curve to IC1. And, the consumer equilibrium point shifts to F. At this point, the consumer is getting maximum satisfaction by spending Rs.350 on 7 units of Giffen Commodity-1 and Rs550 on 11 units of commodity-2. Hence, consumers consumption of Giffen Commodity-1 decreases and quantity demanded of commodity-2 increases with a fall in the price of Giffen Commodity-1.
Similarly, When the price of Giffen Commodity-1 again, reduced to Rs.30, the budget line and indifference curve shifts to AD and IC2. As a result, the equilibrium point shifts to F where budget line AD is tangent to indifference curve IC2. At this point, the consumer is spending Rs150 on 5 units of Giffen Commodity-1 and Rs.750 on 15 units of commodity-2 to get maximum satisfaction.
