Question. Micro and Macro Economics
Answer: 

Question. Explain the central problems of economy.
Answer: (a) What to and how much to produce?
What to produce refers to a central problem in which economy has to make decision which goods and services should be produced. Economy has to decide what type of goods is to be produced and in what quantities.
The economy has to make ‘choice’ because resources are limited and they have alternative uses. The choice can be made between consumer goods (wheat, rice etc.) or capital goods (machine , tools ) or luxuries goods (car , TV etc.) or war time goods(guns , tanks). The increase in production of one good we have to reduce the production of other good.
(b) How to produce?
How to produce refers to a central problem in which economy has to make decision which technique of production should be used.
There are two types of techniques of production :
1. Labour intensive technique : More labour and less capital is used for the production of goods and services.
2. Capital intensive technique : More capital and less labour is used for the production of goods and services.
(c) For whom to produce?
For whom to produce is one of the central problems of economy related with distribution of goods and distributions of income generated due to production.
This problem arises because the output (goods) produced is limited.
This problem is related with distribution of income between four factor of production (land , labour , capital and producer ) in the form of rent , wages , interest and profit. Who should get how much income is the problem. A person who contributes more in production gets higher income. Hence rich can purchase more amounts of good because he has more purchasing power (capacity to buy) than poor.

Question. Why PPC is concave?
Answer: Production possibility curve is concave to origin due to increasing marginal opportunity cost.
Marginal opportunity cost is a rate at which unit of good Y is to be sacrificed for production of one more unit of X. MOC increases as all the resources are not equally efficient in production of all the goods.

Question. Properties of PPC
Answer: (i) PPC is downward sloping : If the country want to produce more of one good, it has to produce less quantity of other goods.
(ii) PPC is concave to the point of origin : Production possibility curve is concave to origin due to increasing marginal opportunity cost. Marginal opportunity cost is a rate at which unit of good Y is to be sacrificed for production of one more unit of X.

Question. Consumer’s equilibrium using indifference approach.
Answer: A consumer is in equilibrium when he is maximizing his satisfaction.
According indifference curve approach a consumer attains equilibrium when Budget Line becomes tangent to Indifference Curve.
At the point of tangency Marginal Rate of Substitution between two goods become equal to Price ratio of two goods or Market rate of exchange.
MRSxy = Px/Py
Slope of Indifference Curve = Slope of Budget Line
MRSxy is the amount of one good (Y) consumer is willing to give up for one more unit of other good (X)
Px/Py is the amount of one good (Y) consumer has to give up for one more unit of other good (X).
On the diagram BL is budget line and IC is Indifference curve. Point A , B and C lie on same IC. So bundles A , B and C will gives same level of satisfaction.
On bundle A and C the expenditure of consumer is equal to his income as bundle A and C lie on budget line. Expenditure on bundle B costs less than income as this point lies below the budget line.
Bundle D is unattainable combination as it lies outside budget line. Bundle E is the combination of optimum choice. It is preferable over all.
E is the point of equilibrium. At this point MRSxy = Px/Py (Slope of Indifference Curve = Slope of Budget Line).

Question. Properties of Indifference curve
Answer: 1.Indifference curve is downward slopping : It means if consumer want to consume more unit of Good X than he has to give up some unit of Good Y.
2. Indifference curve is convex to origin : It means in order to increase the consumption of Good X the Good Y has to be given up (sacrificed) at diminishing rate. MRSxy is diminishing along indifference curve.
3. Higher indifference curve gives higher level of satisfaction : At higher indifference cuve a consumer can have more of both good or more of one good without reducing other good. At higher indifference curve consumer’s preferences are monotonic.
At point A OL and OT are available. But at B on IC2 at least more of one good and no less of other good is available.
4. Two IC never intersect each other.
5. All the combinations on one IC gives same level of satisfaction.

Question. Explain Law of demand with diagram and schedule.
Answer: The law of demand states that other factors are remaining constant, when price of a good falls than the demand of a good rises and vice-versa.
Assumptions : Income and taste – preference of a consumer remain constant, price of related good also remain constant (other factor remaining constant). Explanation with schedule and diagram : 
On ox axis quantity demanded in units and oy axis price in Rs. is given. DD is a demand curve.The demand schedule shows that when price falls from Rs. 3 to Rs. 2 than demand rises from 10 to 20 units of a commodity.

Question. Write relationship between following :
Answer: (i) Income of the buyers and demand for a good
(a) Normal Goods : Goods which are having positive relation with income of a consumer.
It means when income increases demand for normal good also increases.
In the above schedule note that as the income of a consumer increases from Rs.5000 to Rs.6000 the demand of commodity also increases at the same price. For example, when income is Rs.5000 at price of Rs.2 the demand is 20 units and when income increases at the same price of Rs.2 the demand will be 25.
Increase in demand is shown in diagram by rightward (forward) shift of demand curve. It shows that at same price OP the demand increases from OQ to OQ1. DD is initial demand curve and D1D1 is new demand curve.
(b) Inferior Goods : Goods which are having negative relation with income of a consumer. It means when income increases demand for inferior good decreases.
In the above schedule note that as the income of a consumer increases from Rs.5000 to Rs.6000 the demand of commodity decreases at the same price. For example When income is Rs.5000 at price of Rs.2 the QD is 20 units and when income increases at the same price of Rs. 2 the QD will be 10.
Decrease in demand is shown in diagram by leftward (backward) shift of demand curve. It shows that at same price OP the QD decreases from OQ to OQ1. DD is initial demand curve and D1D1 is new demand curve.

Question. Write the relation between Price of other goods(related goods) and demand for the given good.
Answer: Related goods are those goods when price of a good changes the demand of other good also changes.
Related goods are of two types :
(a) Substitute good: Substitute goods are the goods that can be used in place of each other and give the same satisfaction to a consumer. Example Tea and Coffee When price of substitute good increase: When price of substitute good (coffee) increases than the demand of given good (tea) increases at same price . Because relatively become cheaper.
(b) Complementary good : Complementary are the goods that can be used together and therefore they are demanded jointly. Example Car and Petrol When price of Complementary goods increases: When price of Complementary good (Petrol) increases than the demand of given good (Car) decreases at same price . Because due to increase in price of petrol it is demanded less and it is used with car therefore the demand of car also decreases at same price.

Question. Methods of measuring Elasticity of demand:
Answer: (a) Propionates / Percentage / Flux Method of Elasticity of demand: According to this method, price elasticity of demand is measured by dividing the percentage change in quantity demanded by the percentage change in price.
(b) Total expenditure method of Elasticity of demand: It indicates the direction in which total expenditure on commodity changes as a result of change in price of the commodity.

Question. Write Factors affecting price elasticity of demand:
Answer: (i) Nature of commodity: The demand of necessary goods is less elastic. Like wheat,dal,vegetables.
Demand of luxury goods is more elastic. Like Air Conditioner, Car.
(ii) Availability of substitute good: If substitute goods are available for a commodity than demand for the commodity is more elastic. Like Coca cola and pepsi.
If substitute goods are not available for a commodity than demand for the commodity is less elastic. Like salt. 

Question. Relationship between AC and MC
Answer: 1. Both AC and MC derived from TC.
2.Both AC and MC are U shaped.
3.When AC falls MC lies below AC curve
4.When AC rises MC lies above AC curve.
5. MC cuts AC at its minimum where MC=AC.

Question. Supply of a good affected by the following factors :
Answer: 1. Rise in price of inputs (factors) used in production (Pf)
2. Technological improvement (T)
3. Government policy (Tax and Subsidies) (Gp)
1. Rise in price of inputs used in production : When the price of inputs used in production of a good increases, the cost of production also increases. Therefore supply of commodity decreases at constant price because production becomes less profitable.
Cost of production increases due to rise in price of inputs. Supply decreases and supply curve shifts to leftward. S’S’ in new supply curve.
2. Technological improvement : Due to technological progress cost of production reduces therefore supply of commodity increases at constant price.
3. Government Policy :
(a) When government reduces taxes then cost of production decreases therefore supply of commodity increases at constant price.
(b) When government reduces the subsidies then cost of production increases therefore supply of commodity decreases at constant price.

Question. Factors affecting elasticity of supply :
Answer: 1. Nature of input used
2. Nature of commodity
3. Cost of production
1. Nature of input used : If common factors of production are used for production of goods than supply will be more elastic. If specialized factor is used than supply will be less elastic.
2.Nature of commodity : Perishable goods – less elastic supply , durable goods – more elastic supply 3.Cost of production : If cost of productions increases then supply will be less elastic and if cost of production decreases then supply will be more elastic.

Question. Features of Perfect Competition Market
Answer: 1. Large numbers of seller and buyers and its implications :
a) Large numbers of seller: The words ‘large number’ simply states that the number of sellers is large.
Implication: Because of large numbers of sellers a single seller is not able to affect the price of a good and total market supply of a good. Sellers are ‘price-taker’.
b) Large numbers of buyers: The words ‘large number’ simply states that the number of buyers is large.
Implication : Because of large numbers of buyers an single buyer is not able to affect the price of a good and total market demand of a good. Buyers are also ‘price-taker’.
2. Product : Homogeneous Product – All sellers sell same type of (identical) units of a product like same type of color , size , weight , design etc. Therefore the good sold by different firms in the market are equal in the eyes of the buyers.
Implication : The price of the product throughout the market will be the same. Uniform price in the market.
3. Price Control : Due to large number of sellers and buyers they are unable to influence the market price of a good. The firm has no control over price. Firms are ‘price-taker’ as price is determined by the industry.
4. Demand Curve : Demand curve is perfectly elastic as price remains the same at all level of output.
5. Selling Cost : Absence of selling cost because buyers and seller have perfect knowledge about the market.
6. Entry or Exit : Any firm can freely enter or exit from this kind of market.
7. Profit : AR = AC in long run , therefore firm earns normal profit in long run.

Question. Features of Monopoly Market
Answer: 1. Single seller and large number of buyers : One seller selling a product which has no close substitute.
2. Product : There is no close substitute of the product. Therefore , there is no competition form new and existing products.
3. Price Control : The firm has full control over price because there is only one seller in the market.
The firm is a ‘price-marker’ because the firm decides the price of a product.
4. Demand Curve : Downward sloping Inelastic demand curve due to absence of close substitute.
5. Selling Cost : Selling costs are incurred to inform the buyers about product due to lack of perfect knowledge.
6. Entry or Exit : There are some restrictions on the entry of new firms into monopoly industry.
There are patent rights or exclusive control over a technique or raw material.
7. Profit : AR > AC in long run , therefore firm earns abnormal profit in long run.

Question. Features of Monopolistic Market
Answer: 1. Many sellers and Large numbers of buyers : Under monopolistic market many sellers are there in a market. The size of each firm is small. Each firm has limited share supply of good in the market.
2. Product : The unique feature of monopolistic market is product differentiation. In this market the number of firms are many but their product differ from one another in color, shape , size , packing , fragrance , brand etc. Eg. Tea , soap ,
Implication : Because of product differentiation each firm can decide the price of its product. The firm has partial control over price of its product.
3. Price control : Because of product differentiation each firm can decide the price of its product.
Firm is neither a price-taker nor a price-maker but firm has partial control over price due to product differentiation
4. Demand Curve : Downward sloping Elastic demand curve due to presence of close substitute.
5. Selling cost : Heavy selling costs are incurred on sales promotions. Eg. Advertisement on T.V. , hoardings etc.
6. Entry or Exit : Although there is freedom of entry and exit but it is possible only for a competitive firm to enter or leave the industry.
7. Profit : AR = AC in long run , therefore firm earns normal profit in long run.

Question. Features of Oligopoly Market
Answer: 1. Few Firms : Oligopolists are often large firms , each firm producing a significant portion of total market supply. There are only few rival firms. Eg. Car
2. Mutual interdependence : There is a high degree of interdependence between the firms. Price and Output policy of one firm significantly impacts the price and output policy of the rival firms in the market.
For example : If maruti motors reduces price of its cars , tata motors may also do the same. If mauti motors raise the price but it is possible that tata motors will not do the same. It will lead loss to maruti motors.
Firms try to avoid price competition due to the fear of price war. They prefer non-price competition instead of price competition.
3. Price Control : Firms are mutually interdependent to determine the price of product.
4. Demand Curve : It is not possible to determine firm’s demand curve under oligopoly. Simply because it is not possible to predict change in price. When a firm lowers its price , demand for its product may not increase because rival firms may also lower the price.
5. Selling Cost : Due to severe competition and interdependence of the firms, various sales promotion technique are used. For example, T.V. advertisements between Pepsi and Coca cola.
It depends more on non-price competition.
6. Entry and Exit : Patents , large capital investment , Cartel , threat of competition , control over crucial raw material etc. prevent new firms from entering into industry.
7. Profit : AR > AC in long run , therefore firm earns abnormal profit in long run.

Question. Differentiate between (i) Intermediate and good Final 
Answer: 

(ii) Stock Variable and Flow Variable 

(iii) Domestic Income and National Income.

Three methods of calculation of national income
I - Product Method (Value added method):
The first step
GVAmp= Value of Output – Intermediate consumption
Value of output= Sales + Change in stock # Change in stock = (closing stock – opening stock)
The sum of values of GVAmp of all the firms in the economy is GDPmp
NNP Fc (N.I) = GDPmp - Consumption of Fixed Capital/Depreciation+ NFIFA

II Income method:
The first step is to determine NDPfc
NDPfc = Comp. of Emp. + Operating Surplus + Mixed Income
1. Compensation of Employees(Wages and Salaries+ Employer contribution to social security scheme)
2. Operating Surplus (Rent and royalty + Interest + Profit)
(Profit = Corporate Tax + undistributed profit + Dividends NNPfc = NDPfc + NFIFA

III Expenditure Method
The first step to determine GDPmp,
GDPmp=Private Final Consumption Expenditure + Government Final Consumption Expenditure + Gross
Domestic Capital Formation + Net Export
GDCF= NDCF+Depreciation
GDCF =Gross Domestic Fixed Capital Formation + Change in Stock
GDCF= Net Domestic Fixed Capital Formation + Dep. + Change in Stock
GDCF= Gross business fixed investment+Gross residential construction+Gross Public investment
+Change in Stock
NNPfc=GDPmp – Dep. + NFIFA - NIT
Or
NNPfc=GDPmp – Dep. - NFITA - NIT
NDPMP = Private final consumption expenditure + Govt. final consumption expenditure + Net domestic capital formation + Net Exports

(This formula may be directly used when Net domestic capital formation is given Or CFC is not given)
Here,
Net Factor Income From Abroad (NFIFA) = FIFA - FITA
Net Indirect Tax (NIT) = Indirect Tax - Subsidy
Net Exports = Exports - Imports

Formulas for other calculations

Private Income = NDPfc to private sector + NFIFA + Current transfer from government+ Net current transfer from abroad + Interest on National Debt
NDPfc to private sector = NDPfc -NDP fc accruing to government sector
*NDP fc accruing to government sector= Income from property and enterprises to the government + saving of non- departmental enterprises
NDPfc to private sector = NDPfc – Income from property and enterprises to the government – Saving of non- departmental enterprises
Personal Income = Private Income – Corporate Tax – Corporate Savings (undistributed profit)
*Corporate savings or undistributed profit or Net retained earnings of private corporate sector or savings of private sector enterprises may be given
Personal Disposable Income = Personal Income – Direct Taxes paid by household – Miscellaneous receipts GNDI and NNDI
Gross National Disposable Income = GNPmp + Net current transfer from rest of the world (Main formula)
Net National Disposable Income = NNPmp + Net current transfer from rest of the world (Main formula)

Formula of GNP Deflator
It measures the average level of prices of all goods and services that makes GNP.
GNP Deflator = Nominal GNP(GNP at current price) X 100
Real GNP(GNP at constant price)

Question. Explain the problem of double counting. How can we avoid it ?
Answer: Double counting means counting the value of goods and services more than once in the estimation of national income. This problem arises when we consider output of firms are final output therefore we are counting the value of goods at every stage of production more than one time.
But it is the fact that output of one firm may be the input for other firm.
It can be avoided by following ways :
1. Taking Value Addition method in the calculation of the National income.
2. Taking the value of final goods only while calculating national income.

Question. How ‘non-monetary exchange’ and ‘externalities’ are a limitation in taking GDP as an index of welfare?
Answer: GDP is considered as an index of welfare of the people. Increase in GDP means increase in the level of welfare of the people. But some time it not true that Increase in GDP means increase in the level of welfare as given in the following context:
1.Non-monetary exchange : In India, the barter system of exchange is existing in the rural areas where commodities are exchanged for commodities. Payments are made in kind instead of cash. Such transactions are not recorded when we are calculating GDP therefore GDP remains underestimated, it loses the importance as an index of welfare.
2.Externalities :Externalities refers to good and bad impact of an economic activity.
Positive externalities : When a beautiful garden maintained by one person will raises the welfare of other person who is not paying for it. The value of welfare is not included in the estimation of GDP.
3.Negative externalities : Smoke released by factory causes air pollution. People of that locality have to suffer by diseases like asthma which causes the loss of social welfare. But nobody is penalized for it and there is no valuation of it in the estimation of GDP.
Therefore GDP as an index of welfare is not a perfect index because it underestimates the level of welfare.

Question. Problem of double coincidence of wants faced under barter system. How has money solved it ?
Answer: Double coincidence of wants is a pre-conditions for the barter system of exchange.
Double coincidence of wants implies that goods in possession of two different individuals are needed by each other. But it is not always so simple. It is not so simple to find a person who wants your Wheat and at the same time possesses Rice that you want to buy.
Accordingly, under the barter system , exchange remained extremely limited. Money as a medium of exchange solved this problem of double coincidence of wants.

Question. Explain any one functions of money :
Answer: (1) Medium of exchange : It means that money act as a medium for the sale and purchase of goods and services. In the absence of money goods were exchanged for goods. Use of money as medium of exchange has removed the major difficulty of ‘double coincidence of wants’ of the barter system.
Exchange is now become much simpler. It save lot of time and labour. Seller and consumer can sell or purchase the goods and services whenever they desire. It facilitate multilateral trade and gives the economic freedom to the people.
2) Measure of value OR Unit of value : It means each goods and services is measured by money.
Measurement of value of any commodity is difficult in barter system. Introduction of money has removed this difficulty. Now each good is value in term of money. Price of car , house , computer , mobile are expressed in term of money.
By money we are able to construct development plans, we can calculate cost , revenue , profit , national income , PCI etc.
3) Store of value : Store of value means storing of purchasing power for future use. Individual s try to save a part of their income for their future requirement.
It was not possible to store value in barter system. In barter system purchasing power was stored in form of goods or livestock. Goods might depreciate and livestock may die.
4) Standard deferred payment : Deferred payment refers to those payments which are made sometimes in the future. Payment of loans also refers to the deferred payments.
When we borrow money from somebody, we have to return both the principal as well as interest amount.
It is difficult to make such transactions in term of goods and services.

Question. Explain th process of Credit Creation of Commercial Bank
Answer: Credit creation is a process of creating new deposits from initial deposits.
This process depends on amount of Initial Deposits and Legal Reserve Ratio(LRR).
Money Multiplier = 1 ÷ LRR
If LRR = 20% than Money Multiplier will be 5 and
As per above schedule suppose the initial deposit in bank is Rs.100 and the LRR is 20% than banks can keep Rs.20 as cash reserve and remaining Rs.80 can give as a loan.
Those who receive these Cheques will deposit the cheques in their account. The deposits will increases by Rs.80 with banks.
The LRR is 20% therefore banks can keep Rs.16 as cash reserve and remaining Rs.64 can give as a loan.
The process of deposit creation comes to an end when : Total of LRR = Initial Deposit
Money Multiplier = 5 (MM = 1 ÷ LRR , MM= 1÷20% = 5)
Money Creation(New Deposits) = Rs.500 (MC = Initial Deposit ÷LRR)

Question. Explain any one functions of Central Bank (RBI) :
Answer: Central bank : It is the apex institution of a country’s monetary system.
(1) Banker to the Government : Central Bank is a Banker, Agent and Financial Advisor to the Government.
As an Agent to the Government it buys and sells securities on behalf of the Government.
As an Advisor to the Government it helps the Government in making policies to regulate money market.
Central Bank also has responsibility of managing the public debt.
2) Banker’s Bank : As the Banker to the bank the Central Bank holds a part of the cash reserves of banks and give them short term loan. The banks have to deposit a fix ratio of their total deposits with the Central Bank. The purpose of this policy is to control the supply of money in the market.
The Central Bank keeps changing CRR , SLR , and Repo Rate to maintain stability in the money market.
3) Lender of the last resort : Many times Commercial banks create liabilities more than their cash reserve. Sometimes when bank suffer the crises of money and fails to meet their financial requirements they approach to Central Bank.
4) Bank of issue : The Central Bank is the sole authority for the issue of currency in the country. All the currency issued by the Central Bank is its monetary liability.

Question. Write any one measures of credit control by RBI
Answer: 1) Bank Rate: The rate of interest at which the Central Bank gives loan to commercial banks.
On the basis of bank rate commercial banks determine the rate of interest on loan which is required by borrower. Bank rate affects the demand for loan (credit) by customer.
If bank rate is High than demand for loan reduces by customers therefore supply of money decreases in the market. This policy is used by Central bank when there is Excess demand in the economy
2) CRR(Cash Reserve Ratio) : It refers to the minimum percentage of a bank’s total deposits that commercial bank have to keep with central bank.
This CRR is fixed by Central Bank. It changes time to time to control the supply of money in the market.
CRR specifies the maximum limit of loan that commercial banks are able to give to their customers.
CRR is decreased to increase the supply of money in the market during the situation of Deficient demand in the economy. Now the bank has more money with them to give more amount of loan to their customer.
3) SLR(Statutory Liquidity Ratio) : It refers to the minimum percentage of a bank’s total deposits that commercial bank have to keep with themselves in the form of cash or liquid assest.
SLR is decreased to increase the supply of money in the market during the situation of Deficient demand in the economy. Now the bank has more money with them to give more amount of loan to their customer.
4) Open market operations : Open market operation means buying and selling of government securities by Reserve Bank of India in open market.
Buying and selling of securities by Central Bank affect the supply of money in the market. Buying of securities by the Central Bank increases the supply of money in the economy. Selling of securities by the Central Bank decreases the supply of money in the economy.
During the situation of Deficient Demand the Central Bank buys securities.
Selling of securities leads to decrease in the supply of money with Public and Commercial Banks.
5) Margin requirement : It is the difference between value of securities and the loan granted by the bank against this security.
Example : When MR = 20%
If a person produces securities of Rs.1,0000 to bank than bank gives him loan of Rs.80,000
This MR is fixed by Central Bank. It changes time to time to control the supply of money in the market.
MR specifies the maximum limit of loan that commercial banks are able to give to their customers.

Question. Explain Inflationary gap.
Answer: Inflationary gap is the difference between planned demand which is required to maintain full employment level of output and actual demand.. It is the level of demand which is more than the required demand for full employment level of output.
It indicates the economy that how much investment is to be decreased to attain planned (desired) level of aggregate demand.(It may be defined as an excess of aggregate demand over aggregate supply at the full employment level). The inflationary gap results in the rise in general price level which is called inflation.
Inflationary gap occurs when people spend more money than the income generated. This results in unwanted and unplanned decrease in inventories of producers. They want to raise their production but cannot as the economy is already operating at full employment level of output (OYF). This results in inflationary gap (EF).
Measures of correction of Inflationary Gap :
a. The RBI increases the Bank Rate, CRR, SLR, Margin requirement and sell securities from open market.
b. The Government should decrease its expenditure on public programme and increases the taxes.

Question. Write any one objective of Government budget:
Answer: 1.Re-distribution of Income : To reduce inequality of income redistribution of income is one of the major objective of government budget to promote inclusive growth(includes all sections of the society).
Through taxes on the income of rich people their purchasing power is reduced and through expenditure on subsidies, unemployment allowances , old age pension etc. Purchasing power of poor people can be increased. As a result the gap between rich and poor is minimized.
2.Re-allocation of resource : Sometimes demand and supply forces fails to allocate resources efficiently.
Budget helps to re allocate the resources. For the welfare of the society government has to allocate resources for the development of roads, dams, education, health energy generation etc. Private sector will allocate their resource where is high profit at low cost. Production of harmful goods like liquor , cigarette can be discouraged through heavy taxation and production of welfare / useful goods like milk, food, khadi can be encouraged through subsidies.
3.Economic Stability : It means absence of fluctuations in prices. Economic stability encourage the investment and increase the growth rate of economy. Through expenditure and revenue policy the government maintains the economic stability.
During Deflation / Deficient demand, taxes and public borrowings are reduced while government expenditure is increased to increase the purchasing power of the people.

Question. Difference between (i) Capital Expenditure and Revenue Expenditure (ii) Capital Receipt and Revenue Receipt (iii)
Answer: 

Capital Receipt Revenue Receipt

Direct Taxes Indirect Taxes

Question. Explain fiscal , revenue and primary deficit and its implications.
Answer: (1) What is fiscal deficit ? Explain its implications.
Fiscal deficit is the excess of total expenditure over total receipts other than borrowing
Fiscal deficit = Total budget expenditure(RE + CE) – Total budget receipts(RR + CR other than borrowing)
Fiscal deficit indicates how much total borrowing required by the government (from RBI ,Abroad
,Home). It shows government’s dependence on borrowing. When the government borrowing increases ,its liability also increases to repay the loan with interest.
Implications of fiscal deficit :
1. Causes inflation : Government borrowing includes borrowing from RBI. To meet the deficit requirement of the government sometime RBI prints the new currency which increases the supply of money in the market. When supply of money increases in the market than demand of goods and services also increases, this causes rise in the prices of goods and services.
2. Increase in Foreign dependence : Government borrowing includes borrowing from Abroad. It increase our dependence on other countries. Lender country will interfere and influence our political and economic policies. It increases our economic slavery.
3. Financial burden on future generation : Government borrowing includes borrowing form general public. The future generation has to repay the loan and mounting interest.This repayment of loan and interest consumes our national income hence our GDP growth and investment remains low.
(2) What is Revenue Deficit ? Explain its implications.
Revenue deficit is the excess of revenue expenditure over revenue receipts.
Revenue deficit = Revenue Expenditure(RE) – Revenue Receipts(RR)
Implications of revenue deficit :
1. Hardship for the poor people :Government has to reduce the revenue expenditure like subsidies, student’s scholarship ,old pension. It causes difficulty to people with low income group.
2. Causes fiscal deficit : Government has to borrow from RBI, Abroad and general public to meet the consumption needs. It causes fiscal deficit.
3. Disinvestment : To meet the deficit requirement of the government sometime government has to sell public properties to private enterprises.
(3)What is primary deficit ? Explain its implication.
Primary deficit is equal to the Fiscal deficit minus Interest payments.
Primary Deficit = Fiscal Deficit - Interest Payment
If Primary deficit is zero, means FD = IP

Question. Difference between (i) Balance of Payment and Balance of Trade (ii) current account and capital account of BOP account 
Answer:

Basis Current oAccunt Capital Account

Question. (i) autonomous and accommodating transactions of BOP account and (ii)devaluation and depreciation
Answer: 

Devaluation Depreciation

Question. Explain the effect of depreciation domestic currency on exports.
Answer: Depreciation of domestic currency means rise in the price of foreign currency (or fall in the price of domestic currency) Eg. 1$ = 50 Rs. to 1$ = 65 Rs.. It means that now the foreigner (American) has to pay less Rs.to buy one unit of good from our country (India). This reduces the price of domestic goods for foreign buyers. So one unit of foreign currency can now buy more goods and services from India.
Exports become cheaper. The demand for exports may rise.

Question. Explain the relation between foreign exchange rate and supply for it.
OR When price of foreign currency rises, its supply rises. Explain why ?
Answer: Supply curve of foreign exchange is upward sloping due to positive relationship between supply for foreign exchange and foreign exchange rate.
In diagram, on ox axis supply for foreign exchange (US dollar) and on oy axis foreign exchange rate is given. The supply curve (S$) is upward sloping. This means that when foreign exchange rate increases than supply for foreign exchange also rises. Due to the rise in the price of foreign exchange the domestic goods become cheaper (to America) as a result exports will increase. Thus the supply for foreign exchange will also increase.
Sources of Supply for foreign exchange :
1. It comes through exports of goods and services.
2. Recovery of international loans.
3. Through Foreign Direct Investment in domestic market.
4. By receiving gifts and grants from other country.
5. When foreigner purchase assets like land , shares , bonds etc. in domestic market.

Question. How the foreign exchange is determined? Explain with diagram.
Answer: Exchange rate in a free exchange market is determined at a point , where demand for foreign exchange is equal to the supply of foreign exchange.
In diagram, on ox axis Quantity demanded and Quantity Supplied of foreign currency (US$) is given. On oy axis foreign exchange rate is given which shows how many rupees are required of 1 US dollar.
The demand curve (D$) is downward sloping. This means that when foreign exchange rate increases less foreign exchange is demanded.
The supply curve (S$) is upward sloping. This means that when foreign exchange rate increases than supply for foreign exchange also rises.
The demand curve (D$) intersect the supply curve (S$) at point E , which determines equilibrium foreign exchange rate OP$ and equilibrium quantity of foreign exchange OQ$.

Question. What do you mean by ‘for whom to produce’?
Answer : This central problem is related with distribution of goods and distribution of income.
