What is the total product of input?

Why does the SMC curve cut the AVC curve at the minimum point of the AVC curve? 

Let the production function of a firm be Q=5L1/2K1/2Q=5L1/2K1/2 Find out the maximum possible output that the firm can produce with 100 units of LL and 100 units of KK.

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

What do the long-run marginal cost and the average cost curves look like? 

When does a production function satisfy decreasing returns to scale? 

Explain the relationship between the marginal products and the total product of an input. 

Why is the short-run marginal cost curve 'U'-shaped? 

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

What is the law of variable proportions? 

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?

Explain market equilibrium.

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?

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

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

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 do you mean by complements? Give examples of two goods which are complements of each other.

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?

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

Discuss the central problems of an economy.

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

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 are the characteristics of a perfectly competitive market?

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.

If the monopolist firm of Exercise 3 was a public sector firm. The government set a rule for its manager to accept the government fixed price as given (i.e. to be a price taker and therefore behave as a firm in a perfectly competitive market). And the government has decided to set the price so that demand and supply in the market are equal. What would be the equilibrium price, quantity and profit in this case?

Discuss the subject matter of economics.
