Income changes and the The Income-Consumption Curve (ICC)

Case 1 Case 2 Case 3



The lefthand panel above depicts one example of an Income-Consumption Curve (ICC). Derive the ICCs for the other cases shown. For each case:
    Step 1: Draw a second budget.line (BLb) tangent to Ub.
    Step 2: Label the consumer optimum as point 'b'.
    Step 3: Draw an income-consumption curve (ICC) through points 'a' and 'b'.

Decide whether good X and good Y are normal (N) or inferior (I) goods for each of the three cases and write down products that might be real-world examples for each case ((Available online (Java): (i) Basic geometry and (ii) Examples)):
  Case 1 Case 2 Case 3
Normal (N) or inferior (I)
   Good X:      
   Good Y:      
Example:
   Good X =      
   Good Y =
