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. 

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

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?

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

a) Increase

b) Decrease

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 market equilibrium.

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

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

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? 

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

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?

A monopoly firm has a total fixed cost of Rs 100 and has the following demand schedule:

Find the short run equilibrium quantity, price and total profit. What would be the equilibrium in the long run? In case the total cost is Rs.1000, describe the equilibrium in the short run and in the long run.

What do you mean by a normal good?

What happens to the budget set if both the prices as well as the income double?

List the three different ways in which oligopoly firms may have.

Suppose there are two consumers in the market for a good and their demand functions are as follows:

d1(p) = 20 – p for any price less than or equal to 20, and d1(p) = 0 at any price greater than 20.

d2(p) = 30 – 2p for any price less than or equal to 15 and d1(p) = 0 at any price greater than 15.

Find out the market demand function.

At which point does the SMC curve intersect the SAC curve? Give a reason in support of your answer. 

If duo poly behavior is one that is described by Cornet, the market demand curve is given by the equation q = 200 - 4p and both the firms have zero costs, find the quantity supplied by each firm in equilibrium and the equilibrium market price. 

Consider a market where there are just two consumers and suppose their demands for the good are given as follows:

Calculate the market demand for the good.

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

Comment on the shape of MR curve in case when TR curve is a

(a) Positively sloped straight line

(b) Horizontal straight line
