What are the total fixed cost, total variable cost and total cost of a firm? How are they related?
Total Fixed Cost: This refers to the costs incurred by a firm in order to acquire the fixed factors for production like cost of machinery, buildings, depreciation, etc. In short run, fixed factors cannot vary and accordingly the fixed cost remains the same through all output levels. These are also called overhead costs. Total Variable Cost: This refers to the costs incurred by a firm on variable inputs for production. As we increase quantities of variable inputs, accordingly the variable cost also goes up. It is also called Prime cost or Direct cost and includes expenses like -wages of labour, fuel expenses, etc.
Total Cost (TC): The sum of total fixed cost and total variable cost is called the total cost.
Total cost = Total fixed cost + Total variable cost
TC = TFC + TVC Relationship between TC, TFC, and TVC:
1) TFC curve remains constant throughout all the levels of output as fixed factor is constant in short run.
2) TVC rises as the output is increased by employing more and more of labour units. Till point Z, TVC rises at a decreasing rate, and so the TC curve also follows the same pattern.
3) The difference between TC and TVC is equivalent to TFC.
4) After point Z, TVC rises at an increasing rate and therefore TC also rises at an increasing rate.
5) Both TVC and TFC is derived from TC i.e. TC = TVC + TFC
What is the total product of input?
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.
Why does the SMC curve cut the AVC curve at the minimum point of the AVC curve?
When does a production function satisfy decreasing returns to scale?
What do the long-run marginal cost and the average cost curves look like?
Explain the relationship between the marginal products and the total product of an input.
What does the average fixed cost curve look like? Why does it look so?
Why is the short-run marginal cost curve 'U'-shaped?
Explain the concept of a production function

(b) A horizontal line?

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?
Suppose there are 20 consumers for a good and they have identical demand functions:
d(p)=10–3pd(p)=10–3p for any price less than or equal to 103103 and d1(p)=0d1(p)=0 at any price greater than 103.
Explain why the demand curve facing a firm under monopolistic competition is negatively sloped.
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)?
A shift in demand curve has a larger effect on price and smaller effect on quantity when the number of firms is fixed compared to the situation when free entry and exits is permitted. Explain.
Consider a market where there are just two consumers and suppose their demands for the good are given as follows:

If a consumer has monotonic preferences, can she be indifferent between the
bundles (10, 8) and (8, 6)?
What do you mean by substitutes? Give examples of two goods which are substitutes of each other.
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?
Compare the effect of shift in the demand curve on the equilibrium when the number of firms in the market is fixed with the situation when entry-exit is permitted.
Suppose the price elasticity of demand for a good is – 0.2. How will the expenditure on the good be affected if there is a 10 % increase in the price of the good?
