How will a change in the price of coffee affect the equilibrium price of tea? Explain the effect on equilibrium quantity also through a diagram. 

Suppose the price at which the equilibrium is attained in exercise 5 is above the minimum average cost of the firms constituting the market. Now if we allow for free entry and exit of firms, how will the market price adjust to it?

Suppose the market determined rent for apartments is too high for common people to afford. If the government comes forward to help those seeking apartments on rent by imposing control on rent, what impact will it have on the market for apartments?

Explain through a diagram the effect of a rightward shift of both the demand and supply curves on equilibrium price and quantity.

When do we say that there is an excess supply for a commodity in the market?

How are equilibrium price and quantity affected when income of the consumers

a) Increase

b) Decrease

Explain market equilibrium.

Explain how price is determined in a perfectly competitive market with a fixed number of firms.

In what respect do the supply and demand curves in the labor market differ from those in the goods market?

Suppose the demand and supply curves of salt are given by:

(a) Find the equilibrium price and quantity.

(b) Now, suppose that the price of an input that used to produce salt has increased so, that the new supply curve is qs = 400 + 3p

How does the equilibrium price and quantity change? Does the change conform to your expectation?

(a) Suppose the government has imposed at ax of Rs 3 per unit of sale on salt. How does it affect the equilibrium rice quantity? 

Explain the concept of a production function

What would be the shape of the demand curve so that the total revenue curve is?

(a) A positively sloped straight line passing through the origin?

(b) A horizontal line?

Discuss the central problems of an economy.

What are the characteristics of a perfectly competitive market?

What do you mean by the budget set of a consumer?

What is the total product of input?

From the schedule provided below calculate the total revenue, demand curve and the price elasticity of demand:

What do you mean by the production possibilities of an economy?

How are the total revenue of a firm, market price, and the quantity sold by the firm related to each other?

What is budget line?

Briefly explain the concept of the cost function. 

Suppose a consumer’s preferences are monotonic. What can you say about her preference ranking over the bundles (10, 10), (10, 9) and (9, 9)?

Let the production function of a firm be Q=2 L2 K2Q=2 L2 K2

Find out the maximum possible output that the firm can produce with 5 units of LL and 2 units of KK. What is the maximum possible output that the firm can produce with zero units of LL and 10 units of KK?

Can there be a positive level of output that a profit-maximising firm produces in a competitive market at which market price is not equal to marginal cost? Give an explanation.

The following table shows the total cost schedule of a firm. What is the total fixed cost schedule of this firm? Calculate the TVC, AFC, AVC, SAC and SMC schedules of the firm.

Explain the concept of a production function

What are the average fixed cost, average variable cost and average cost of a firm? How are they related? 

What does the average fixed cost curve look like? Why does it look so? 

Suppose a consumer can afford to buy 6 units of good 1 and 8 units of good 2
if she spends her entire income. The prices of the two goods are Rs 6 and Rs 8
respectively. How much is the consumer’s income?

What is the average product of an input?
