What is a production possibility frontier?
The production possibility frontier (PPF) refers to a curve that shows various alternative combinations of two goods that can be produced with efficient utilization of the given resources and technology. It is also called the production possibility curve (PPC). All the points lying on the PPC, that is curve AE, are associated with different quantities of good 1 and good 2 produced, by employing the available resources fully and in an efficient manner. While any point lying under the curve, like F, depicts inefficiency or under utilisation of available resources. Whereas any point lying outside the curve, like Z, depicts over utilisation of the available endowment of resources and technology; making it non-feasible.
What is the supply curve of a firm in the long run?
The market price of a good changes from Rs 5 to Rs 20. As a result, the quantity supplied by a firm increases by 15 units. The price elasticity of the firm’s supply curve is 0.5. Find the initial and final output levels of the firm.
A firm earns a revenue of Rs 50 when the market price of a good is Rs 10. The market price increases to Rs 15 and the firm now earns a revenue of Rs 150. What is the price elasticity of the firm’s supply curve?
Distinguish between a centrally planned economy and a market economy.
How does the imposition of a unit tax affect the supply curve of a firm?
A consumer wants to consume two goods. The prices of the two goods are Rs 4
and Rs 5 respectively. The consumer’s income is Rs 20.
(i) Write down the equation of the budget line.
(ii) How much of good 1 can the consumer consume if she spends her entire
income on that good?
(iii) How much of good 2 can she consume if she spends her entire income on
that good?
(iv) What is the slope of the budget line?
Questions 5, 6 and 7 are related to question 4.
What is the relation between market price and average revenue of a price-taking firm?
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.
Suppose your friend is indifferent to the bundles (5, 6) and (6, 6). Are the preferences of your friend monotonic?
What do the long-run marginal cost and the average cost curves look like?
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.
Price (Rs.) | SS1 (kg) | SS2 (kg) |
---|---|---|
0 1 2 3 4 5 6 7 8 |
0 0 0 1 2 3 4 5 6 |
0 0 0 0 0.5 1 1.5 2 2.5 |
What does the average fixed cost curve look like? Why does it look so?
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?
Explain through a diagram the effect of a rightward shift of both the demand and supply curves on equilibrium price and quantity.
Using supply and demand curves show how an increase in the price of shoes affects the price of a pair of socks and the number of pairs of socks bought and sold.
Distinguish between microeconomics and macroeconomics.
