- Is utility ordinal?
- What are indifference curves? What do you mean by MRS?
- Can two indifference curves intersect?
- Are averages preferred to extremes? Explain using the concept of indifference curves.
- Distinguish between budget line and budget set. Derive the slope of budget line and provide its economic intuition.
- How would the budget line shift if the price of x changes?
- How the budget line would shift if income of the consumer increases?
- How the budget line would shift in case of taxes and subsidies?
- Suppose there is a tax on y after y bar. How would the budget set looks like in this case?
- Draw the budget set in case of rationing of any one of the product.
