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?

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?

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

a) Increase

b) Decrease

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.

How is the optimal amount of labor determined in a perfectly competitive 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?

What is the value of the MR when the demand curve is elastic?

What is the reason for the long run equilibrium of a firm in monopolistic competition to be associated with zero profit?

Find out the maximum possible output for a firm with zero units of L and 10 units of K when its production function is Q = 5L = 2K. 

At the market price of Rs 10, a firm supplies 4 units of output. The market price increases to Rs 30. The price elasticity of the firm’s supply is 1.25. What quantity will the firm supply at the new price?

Will a profit-maximising firm in a competitive market produce a positive level of output in the long run if the market price is less than the minimum of AC? Give an explanation.

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

What is the supply curve of a firm in the short run?

Consider a market with two firms. The following table shows the supply schedules of the two firms: the SS₁ column gives the supply schedule of firm 1 and the SS₂ column gives the supply schedule of firm 2. Compute the market supply schedule.

There are three identical firms in a market. The following table shows the supply schedule of firm 1. Compute the market supply schedule.

Consider a market with two firms. In the following table, columns labelled as SS₁ and SS₂ give the supply schedules of firm 1 and firm 2 respectively. Compute the market supply schedule.
