Opportunity cost is the value of the next best alternative foregone when availing a particular alternative. (1) 2. A rise in price. (1) 3. It is inelastic. (1) 4. A firm is said to be a price taker when it has no option but to sell the product at a price determined at the industry level. (1) 5. Es =1. (1) 6. The consumer will purchase 4 units because at this consumption level marginal utility equals price. (1) At consumption level of less than 4 units MU is greater than price. Therefore there is scope of increasing gain by purchasing more. (1) If he buys more than 4 units MU becomes less than the price. Therefore, there is scope of increasing gain by purchasing less. (1) The Law of supply states that there is direct relation between price and supply of a good, other things remaining the same. (1) The assumption means that factors, other than the own price of the good, determining supply remain unchanged. (1) Some of these other factors are prices of other goods, prices of inputs, taxes, technology, etc. (1) 7. 8. ATC (Rs.) AVC (Rs.) MC (Rs.) 1 54 30 30 2 36 24 18 3 32 24 24 4 9. Output (units) 33 27 36 Product differentiation means that buyers differentiate between the products produced by different firms. Therefore, they are willing to pay different prices for the products of different firms. Different groups of buyers prefer products of different firms. This gives an individual firm some monopoly power, i.e. power to influence the demand for its product by changing price. 24 ( x 6) (3) OR The freedom ensures that firms earn just the normal profits in the long run. If the existing firms earn above-normal profits, new firms enter the industry, raise supply, which brings down the price. The profits fall till each firm is once again earning only the normal profits. If the existing firms are having losses, the firms start leaving, supply falls and price goes up. The price continues to rise till the losses are wiped out and firms are just earning normal profits. (3) 10. The three problems of allocation of resources are : 1. 2. How, i.e. by which technology, to produce? 3. 11. What goods to produce and in what quantities? For whom to produce ? (1 x 3) Rise in the price of a substitute good makes good X relatively cheaper. Y Price P (1) D 1 O Q1 Q 2 D 2 X Qty . This raises demand for X at the same price. Graphically the demand curve of good shifts to the right from D1 to D2 and the consumer s demand for X rises from OQ1 to OQ2 at price OP. (1) Y Price P (1) D2 O Q2 Q1 25 D1 Q ty . X Rise in price of a complementary good reduces demand for the complementary good and in turn reduces demand for good X. Graphically the demand curve of good X shifts to the left from D1 to D2 and the demand for X falls from OQ1 to OQ2 at price OP. (1) OR Y Price P (1) D 2 D 1 O Q1 Q 2 X Qty . Rise in income increases demand of a normal good. Graphically the demand curve of the good shifts to the right from D1 to D2. The demand at the same price OP rises from OQ1 to OQ2. (1) Y Price P (1) D1 D2 O Q2 Q1 Qty . X Rise in income decreases demand of an inferior good. Graphically, the demand curve of the good shifts to the left from D1 to D2. The demand at the same price OP falls from OQ1 to OQ2 . (1) For Blind Candidates in lieu of Q. No. 11. Rise in the price of a substitute makes the good X relatively cheaper and therefore, raises demand for X at the given price of X. (1) Fall in the price of a substitute makes the good X relatively dearer and, therefore, reduces demand for X at the same price of X. (1) 26 Rise in the price of a complementary good reduces demand for the complementary good and in turn reduces demand for good X at the same price of X. (1) Fall in the price of a complementary good raises demand for the complementary good and in turn raises demand for good X at the same price of X. (1) OR Rise in income increases demand for a normal good. (1) Fall in income reduces demand for a normal good. (1) Rise in income decreases demand for an inferior good. (1) Fall in income increases demand for an inferior good. (1) Elasticity of demand at a point on a straight line demand curve is measured by the following formula lower segment edd = upper segment Since at different points on the straight line demand curve the value of lower and upper segment is different, so the elasticity of demand at different points on a straight line demand curve will be different. (2) 12. 13. 14. Output (Units) 1 2 3 4 Price (Rs.) 10 9 8 7 MR (Rs.) 10 8 6 4 TR (Rs. 10 18 24 28 The behaviour of total product is summed up as the Law of Variable Proportions. There are three phases in the behaviour of TP. Ist Phase : TP rises at increasing rate IInd Phase : TP rises at decreasing rate IIIrd Phase : TP falls and The three phases in the behaviour of MP are : Ist Phase : MP rises. IInd Phase : MP falls and is positive. IIIrd Phase : MP falls but becomes negative. 27 (2) ( x 8) (3) (3) OR The behaviour of TP is technically termed as Returns to Scale. There are three possibilities: (1) TP rises in greater proportion than the rise in inputs, called Increasing Returns to Scale. For example : Suppose there are only two inputs, labour (L) and Capital (K). Suppose 1K + IL produce 100 units and 2K + 2L produce 250 units. Input rises by 100% while the output rises by 150% (1+1) (2) (3) 15. TP rises in the same proportion as rise in inputs, called Constant Returns to Scale. For example, suppose 1K+1L produce 100 units and 2K+2L produce 200 units, both inputs and TP rise in the same proportion. (1+1) TP rises in smaller proportion than the rise in inputs, called Decreasing Returns to Scale. For example, Suppose 1K+1L produce 100 units and 2K+2L produce 190 units, inputs rise by 100% while the output rise by 90%. (1+1) Decrease means less quantity at the same price. (a) If decrease in demand is equal to decrease in supply, there will be no change in the equilibrium price. In the figure, decrease in dd = decrease in SS = E1 E2 Equilibrium price remains the same at OP. (1 ) (1 ) (b) If decrease in demand is greater than decrease in supply, the equilibrium price will fall. In the figure, decrease in dd = AE, while decrease in supply is lower i.e. BE1 Therefore, equilibrium price falls from OP1 to OP2. (1 ) (1 ) 28 For Blind Candidates in lieu of Q. No. 15 (i) (ii) (iii) 16. If the decrease in demand is greater than the decrease in supply, there will be excess supply. This will result in competition among sellers, Price will fall. This will result in rise in demand and fall in supply. These changes continue till price falls to a level at which demand and supply are equal. So in this case equilibrium price will fall. (2) Similarly if decrease in demand is less than decrease in supply, this will result in a rise in equilibrium price. (2) When decrease in demand and supply are equal, there will be no change in equilibrium price. (2) The producer of a good is in equilibrium at that level of output of the good at which he earns maximum profit. (1) There are two conditions of producer s equilibrium : (i) The difference between TR and TC is maximum. (ii.) Total profit falls if one more unit of output is produced. (2) In the diagram, OQ is the equilibrium output with profit equal to AB = AQ BQ. AB is the maximum vertical distance between TR and TC. If more than OQ output is produced total profits fall. (Note : Diagram with straight line TR curve may also be taken as correct). (1) (2) For Blind Candidates in lieu of Q. No. 16 Definition (Same as above) Conditions (Same as above) (1) (2) Total cost and total revenue schedule Output (Units) TR TC Profit 1 10 15 5 2 18 12 6 3 24 21 3 4 28 32 4 The producer will produce 2 units because his profits are maximum at this level of output. 29 (2) (1) SECTION - B 17. Since MPC + MPS =1 and MPC = MPS, therefore, value of MPS = and value of multiplier is 2. (1) 18. Statutory Liquidity Ratio is the ratio of total demand and time deposits of commercial bank which it has to keep in the form of specified liquid assets. (1) 19. Primary deficit = Fiscal deficit - Interest payment. (1) 20. It reduces money supply . (1) 21. If planned savings are greater than planned investment inventories will increase. (1) 22. There are three types of transactions that are recorded in current account of balance of payments account. i. ii. Export and import of services. It includes both factor income and non factor income. iii. Transfer payments. These are unilateral transfers. N.I. = (i) + (ii) + (v) + (vi) + (vii) = 800 + 200 20 + 300 + 100 = 23. Export and import of goods. Rs. 1380 crore. (1x 3) (1) (1 ) ( ) OR GDP@ f.c. = (i) + (vi) + [(iii) + (viii)] + (vii) - (v) = 800 + 450 + 30 + 170 30 120 25. (1 ) ( ) = Rs.1300 crore 24. (1) Double coincidence of want means what one person wants to sell and buy must coincide with what some other person wants to buy and sell. It was very difficult that such coincidence of wants may take place. Money has removed this difficulty. You can sell your goods for money to whosoever wants it and with this money you can buy what you want from whosoever wants to sell that. (3) A commercial bank is a financial institution that performs the functions of accepting chequable deposits and lending. (1) Methods of lending : i. Cash credit ii. Demand loans iii. Overdrafts etc. (Any Two) (1x2) 26. Any two objectives, explanation of each. (1+2) 27. Revenue deficit is the excess of government s revenue expenditure over its revenue receipts. A large revenue deficit means large borrowings for meeting the expenditure on normal functioning of government departments and various services. Large borrowings will result in increased revenue expenditure (interest payment) and a larger revenue deficit. (2) 30 For reducing the revenue deficit the government should reduce its expenditure and raise more tax revenue. 28. (2) Reasons for rise in demand for a foreign currency when its price falls: (i) When price of a foreign currency falls, imports from that country become cheaper. So, imports increase and hence demand for foreign currency rises. (2) (ii) When a foreign currency becomes cheaper in terms of domestic currency, it promotes tourism to that country. As a result the demand for that foreign currency rises. (2) OR Merits of flexible exchange rate system : i. Under this system deficit or surplus in balance of payments is automatically corrected . ii. Under this system there is no need for the government to hold any foreign exchange reserves. iii. It helps in optimum resource allocation etc. (Any two) (1x2) Demerits of flexible exchange rate system : i. ii. 29. It encourages speculation. There can be wide fluctuations in exchange rate which may hamper foreign trade etc. (Any two) (1x2) An economy is in equilibrium when planned expenditure and planned output in the economy are equal. If this equality is achieved at a less than full employment level of output then the economy is in a situation of under full employment equilibrium. (2) (1) OQ1 is the full employment level of output. C+I curve shows aggregate demand at different levels of output. The aggregate demmand is sufficient only for OQ level of output. So at OQ level of output the economy is in equilibrium but it is a situation of under employment equilibrium. For Blind Candidates in lieu of Q. No. 29 Same explanation as above except diagram. 31 (1) 30. (a) It will not be included in domestic product of India as this income is earned outside the domestic (economic) territory of India. (1 ) (b) It will not be a part of domestic product of India as embassy of Japan in India is not a part of domestic territory of India. Hence this income is not earned within the domestic territory of India. (1 ) (c) It will be included in domestic product of India as the branch of American bank is located within the domestic terriroty of India. So it is income earned within the domestic territory of India. (1 ) (d) It will be part of domestic product of India because this income is earned within the domestic territory of India. Indian embassy in Korea is treated as located within the domestic territory of India. (1 ) OR (a) Precautions to be taken under value added method : i. ii. (b) Only value added by production units should be added and not their value of output otherwise it will result in double counting. While estimating value added, sale of second hand goods should not be included. Production of these goods has already been accounted for when these were newly produced. (1 ) (1 ) Precautions to be taken under income method : i. ii. Only factor income should be included, transfer income should not be included because such income is not received for rendering factor services. (1 ) Income from sale of financial assets like shares etc. should not be included. Trading in these assets does not result in production of any good or service. (1 ) 31. C = 100 + 0.5Y C Y C APC = Y 400 300 0.75 500 350 0.70 600 400 0.67 (3) When Y is 400, C = 100 + 0.5 x 400 = 300 Similarly when Y is 500, C is 350 and when Y is 600, C is 400, As income increase from 400 to 600, APC declines from 0.75 to 0.67. Thus as income is increasing APC is decreasing. 32. GNP @ mp = (ix) + (iii) xi) (3) (1) = 1000 +50 20 (1 ) = Rs. 1030 crores ( ) Personal Disposable income = (xiv) (v) (viii) (iv) (xiii) = 700 40 90 110 30 = Rs. 430 crores 32 (1) (1 ) ( ) SAMPLE QUESTION PAPER-II Subject : Economics Class XII Max.
