- Perfectly elastic.
 - Inelastic.
 - Elastic.
 - Unit elastic.
 
- The consumer will be in equilibrium where there is a tangency between price line and indifference curve because at equilibrium point his MRS
 
- Is equal to its price ratio.
 - Is falling.
 - And price ratios are inversely related.
 - Is greater than the price.
 
- The cross-elasticity of demand between petrol and automobile is
 
- Negative.
 - Zero.
 - Positive.
 - Infinite.
 
- Which one of the following will not change the equilibrium price?
 
- Increase in demand.
 - Decrease in demand.
 - Increase in demand and equal increase in supply.
 - Increase in demand and equal decrease in supply.
 
- The Engel curve for an inferior good
 
- Slopes upward.
 - Slopes downward.
 - Is a horizontal line.
 - None of the above.
 
- The shape of Isoquants may be
 
- Convex.
 - Linear.
 - L-Shaped.
 - Any one of the above.
 
- When marginal product is negative, total product
 
- Rises.
 - Declines.
 - Is negative.
 - None of the above.
 
- The marginal cost curve intersects the average cost curve, where average cost is
 
- Maximum.
 - Minimum.
 - Rising.
 - Falling.
 
2. Write short notes on any four of the following: (within 150 words each):   4x4=16
- Point elasticity and Arc Elasticity.
 - Ridge lines.
 - Fixed cost and Variable cost.
 - Marginal rate of technical substitution.
 - The law of equi-marginal utility.
 
Answer the following questions (within 500 words each): 
3. (a) What are microstatics and micro-dynamics? Distinguish between the two approaches.   5+6=11
Or
 (b) What is price elasticity of demand? Mention the factors on which elasticity of demand depends.  2+9=11
4. (a) Compare and contrast between the cardinal utility approach and the indifference curve approach of the theory of consumer’s behaviour. Which one do you consider superior? Justify your answer.    9+2=11
Or
 (b) Explain why – 
- An indifference curve for two normal goods is convex to the origin;
 - Two indifference curves cannot cut each other. 6+5=11
 
5. (a) Using indifference curve analysis, show how price effect of a commodity is decomposed into income effect and substitution effect.   12
Or
 (b) What is an Engel curve? Explain derivation of an Engel curve from an income-consumption curve.     2+10=12
6. (a) Explain the laws of returns to scale.   11
Or
 (b) What is the difference between a production function and an Isoquants? Explain the law of variable proportions with the help of Isoquants.    3+8=11
7. (a) “Short-run average cost curve is relatively more U-shaped than a long-run average cost curve.” Justify.  11
Or
 (b) Draw the short-run and long-run average and marginal cost curves and explain their relationship.   11
