Economics notes-Govt. Budget and the Economy


8. Government Budget and the Economy

Government budget is annual statement of the estimated receipts and proposed expenditure of the govt. over the fiscal year.

Objectives

1. Activities to secure a reallocation of resources: The govt. has to reallocate resources in line with the social and economic policies of the country.

2. Redistributive activities: The govt. redistributes income and wealth in order to reduce inequalities, by expenditures on social security, subsidies, public works, etc.

3. Stabilizing activities: The govt. tries to prevent business fluctuations and maintain economic stability, i.e., high level of employment and price stability (Keynesian economics).

4. Management of Public Enterprises: Govt. undertakes commercial activities such as railways and electricity, which are of the nature of natural monopolies and heavy manufacturing. The management of such enterprises comes under state regulation because if left unregulated, there is a tendency of the monopolist to curtail output in pursuit of maximizing profit. This will lower social welfare.

Impact of govt. budget on the economy

1) Aggregate fiscal discipline: The govt. ought to have a control over its expenditure, given the quantum of its revenue. This is to ensure proper macro economic performance.

2) Allocation of resources based on social priorities: Govt. budget allocates the resources on the basis of its social and economic priorities in order to maximize social welfare.

3) Delivery of services: It measures the effectiveness of its programs and the extent to which the govt. provides achieves its goals.

Components of a govt. budget

A govt. budget is divided into revenue budget and capital budget.

Revenue receipts: They are those which do not create a liability or they do not lead to reduction of assets.
For example, receipts from taxes do not create a liability or it does not reduce assets. 

It may be divided into tax revenue and non-tax revenue. .

Tax revenue includes revenue from direct and indirect taxes imposed by the govt., while non-tax revenue includes revenue from profits earned by govt. enterprises, prices paid for govt. supplied commodities and services. This includes payments for postage, tolls, interest on funds received from govt. corporations such as railways, etc. and interest and dividends on investments made by govt.

Administrative revenue is revenue that arises on account of the administrative function of the govt. Some of the administrative revenue are
1) Fees which are payment to defray the cost of each recurring service undertaken by the govt. primarily in the public interest, but conferring a measurable special advantage on the fee payer. E.g., license fees
2) Fines and penalties which are levied on the violation of a law.
3) Forfeitures of basic surety or bonds are penalties imposed by courts for no-compliance with orders or non-fulfillment of contracts
4) Escheat refers to the govt. claims on the property of a person who dies without having any legal heirs or without leaving a will.

Direct tax
Indirect tax
1. Tax in which the liability and the burden to pay the tax lie on the person.

2. The burden of paying the tax cannot be shifted to others.

3. It is imposed on the property and income of persons.
4. E.g., are income tax, wealth tax and interest tax.
1. Tax in which the liability to pay the tax and the burden of paying the tax can be on different persons.

2. The burden of paying the tax can be shifted to others.

3. It is imposed on production and consumption of commodities.
4. E.g., are sales tax, excise duty and import duty.

Tax revenue
Non-tax revenue
1. It is the revenue receipts that the govt. receives by imposing direct and indirect taxes.

2. E.g., are revenue from income tax, excise duty wealth tax and import duty.
1. It is the revenue receipts that the govt. receives from sources other than tax.

2. E.g., are revenue from interest on govt. loans, dividends and profits of govt. enterprises and external grants from foreign govts.


Capital receipts: While one part of govt. receipts is revenue receipts, the other part is capital receipts. When govt. receives funds either by incurring a liability or by disposing its assets, it is called a capital receipts.

For example, when the govt. raises funds by borrowing, it increases the liability of the govt. Such funds are called capital receipts.

Capital receipts of the Govt. of India can be classified into three. They are
1) recoveries of loans
2) borrowings and other liabilities and
3) other receipts

Revenue receipts
Capital receipts
1. Receipt of govt. which does not increase its liability or it does not reduce the assets of the govt.
2. Sources of revenue receipts are tax and non-tax revenues such as interest , profit and external grants
Govt. receipt which either increases the govt.’s liability or decreases its assets.
2. Sources of capital receipts are recoveries of loans, borrowing and other liabilities and other receipts such as disinvestment.

Budget expenditure: While one part of the govt. budget is receipts, the other part is expenditure. Similar to budget receipts, budget expenditure also can be divided into revenue expenditure and capital expenditure.

Revenue expenditure: An expenditure which does not result in creation of assets nor reduction of liability is called revenue expenditure. Such expenses are incurred for the normal running of the govt. departments. Main examples are salaries and pensions of govt. employees, interest paid by the govt. on the loans raised by it, subsidies and financial grants given by the govt.

Capital expenditure: It is an expenditure which leads to creation of assets or reduction of liabilities,. Some of the examples are the expenditure on purchasing land, buildings, shares as well as loans granted to the State govts., foreign govts., public enterprises and others.

Plan expenditure and Non-Plan expenditure

Plan expenditure: In every five-year and annual plans, the govt. makes several programmes for the development of the economy such as Integrated Rural Development Programme and Jawahar Rozgar Yojna. For the implementation of such programmes, the govt. incurs expenditure. This is known as plan expenditure.

Non-Plan expenditure: When the govt. spends on anything other than the expenditure related to the current five-year plan or annual plan, it is known as non-plan expenditure.

Developmental and Non-Developmental Expenditure

Budget expenditure of a govt., whether Plan or Non-Plan, Revenue or Capital, can also be classified into developmental and non-developmental expenditure.
  Developmental expenditure: It is the expenditure on activities which are directly related to economic and social development of the country. Examples of developmental expenditure are expenditure on agricultural and industrial development, education, health, social welfare and scientific research.
Non-developmental expenditure: Govt. expenditure on essential general services such as defence and administration is known as non-developmental expenditure. This expenditure is an essential part of the development process. This expenditure does not directly contribute to the national product but it lubricates the wheels of economic development.

Developmental expenditure
Non-developmental expenditure
1. Expenditure on activities which are directly related to economic and social development of the country.
2. E.g. are expenditure on agriculture, health and education.
1. Expenditure on essential general services of the govt.

2. E.g. are expenditure on defence and administration.



Types of budget

Budget can be classified into balanced, surplus or deficit budget.

Balanced budget: A balanced budget is one in which the estimated revenue equals the estimated expenditure. Supposing that the only source of revenue for the govt. is a lump sum tax. It means that the tax amount is equal to the govt. expenditure.

The decrease in aggregate demand (due to the tax) is equal to MPC times the tax. Now, the aggregate demand will increase because of the expenditure. Increase in aggregate demand will be equal to 1 – MPC multiplied by expenditure. Thus, the increase in aggregate demand due to expenditure will be more than the fall in aggregate demand due to tax. Thus, a balanced expenditure will slightly increase the aggregate demand. A balanced budget is a good policy to bring the economy which is at near-full employment to full employment.

Surplus budget: It is a budget in which the estimated  revenue is more than the estimated expenditure. Supposing that the only source of revenue is a lump sum tax, its effect on the economy will be to decrease aggregate demand. Due to tax, aggregate demand will fall by MPC times of tax. The effect of govt. expenditure is to increase aggregate demand.

If tax is sufficiently higher than expenditure, the net effect of the budget will be to decrease aggregate demand. This is done at times of inflation that arises out of excess demand.

 Deficit budget: A deficit budget is one in which the estimated revenue is less than estimated expenditure. This means that tax is less than expenditure. Again supposing that the only source of revenue is a lump sum tax, The reduction in aggregate demand (due to tax) is equal to MPC times the tax. The increase in aggregate demand (due to expenditure) is by an amount equal expenditure. Now, if tax is sufficiently les than the expenditure, then the reduction in aggregate demand will be less than the increase in aggregate demand. The net effect of this is to increase aggregate demand.

This is done when the economy is facing recession due to deficient demand.

Types of deficit

There are four different concepts of deficit. They are budget deficit, revenue deficit, primary deficit and fiscal deficit.

1. Revenue deficit: When revenue expenditure is more than revenue receipts, the shortfall is known as revenue deficit.

Revenue deficit = Total revenue expenditure – total revenue receipts

Though revenue expenditure and revenue receipts do not affect either liabilities or assets, revenue deficit affects them.  When revenue expenditure is more than revenue receipts, this deficit is met either by borrowing or by selling the assets. Thus revenue deficit either increases the govt. liabilities or reduces its assets.

2) Fiscal deficit: When the total govt. expenditure is more than the total govt. receipts, the shortfall is known as fiscal deficit.
Fiscal deficit = Total govt. expenditure - Total govt. receipts.

Importance of fiscal deficit: Fiscal deficit is an overall measure of the total borrowing requirements of the govt. It shows how much the govt. needs to borrow, in order to meet its budget expenditure.

For example, in the Indian govt. budget of 2000 – 2001, fiscal deficit is about 33% of the total budget expenditure. It means that the govt. has to borrow 33 paise in order to finance 1 rupee.

Fiscal deficit creates many problems for the economy. With borrowing, the govt.’s liability in future increases because it has to pay the interest and repay the loans. Payment of interest increases revenue expenditure Increased revenue expenditure may lead to higher revenue deficit. In order to finance the higher revenue deficit, the govt. borrows more and more which again increases its fiscal deficit. This creates a vicious circle.

Every year, the govt. has to borrow, just to finance interest payments. Repayment of loans is another problem. That is why the Indian govt. is trying to reduce fiscal deficit as much as possible.

iii) Primary deficit:  It is equal to the fiscal deficit less interest payments.
Thus, primary deficits = Fiscal deficit – Interest payments 
It shows the borrowing requirements of the govt. net of interest payment.




Economics notes-Foreign Exchange


9. Foreign Exchange Rate: Meaning and Determination

Foreign exchange rate: It is the price of one currency in terms of another. It is the rate at which exports and imports of a country are valued at given point in time.

Importance of foreign exchange rate:
1. A country’s economic stability is indicated, among other things, by the stability in its exchange rate.
2. The strength of domestic currency is seen against that of currencies of other countries in the world.
3. Earnings from exports and payments for imports are directly affected by the exchange rate.

Foreign exchange market: It is the market where national currencies are traded for one another.

Foreign exchange market performs three main functions. They are:
1) to transfer purchasing power between countries (transfer function)
2) to provide credit channels for foreign trade (credit function) and
3) to protect against foreign exchange risks (hedging function)

Demand for foreign exchange is the demand for foreign currencies by the residents of a country. Similarly, supply of foreign exchange is the demand for home country currency by the non-residents of the country.

Demand and supply side

People’s intention to transact in the foreign exchange market depends upon their demand and supply position with respect to foreign exchange.

Demand side: Demand for foreign exchange depends upon the following factors.
1) to purchase goods and services from other countries
2) to send  gifts abroad
3) to purchase financial assets abroad and
4) to speculate on the value of foreign currencies.

Supply side: Flow of foreign currencies into the country depends upon the following.
1) foreigners purchasing home country’s goods and services through exports.
2) foreign investment in the home country through joint ventures or through financial market operations and
3) foreign currency flow into the economy due to currency dealers and speculators

Equilibrium in the foreign exchange market

Foreign exchange market, like any other market contains a downward sloping demand curve and an upward sloping supply curve. The price on the Y-axis is stated in terms of domestic currency (that is, how many rupees for one dollar). The horizontal X-axis measures the quantity demanded and supplied of foreign exchange (say, US $).

The intersection of demand and supply curves determines the equilibrium exchange rate and the equilibrium quantity of the foreign currency.













The demand curve (D$) is downward sloping. It means that less foreign exchange is demanded as the exchange rate increases. This is because the rise in the price of foreign exchange will increase the rupee cost of foreign goods, which makes them more expensive. As a result, imports decline. Thus, the demand for foreign exchange will also decrease.

The supply curve (S$) is upward sloping which means that supply foreign exchange increases as the exchange rate increases. This makes home country’s goods become cheaper to foreign since the rupee is depreciating in value.

Disequilibrium conditions in the foreign exchange market: An increase in the demand for US  dollars in India will cause the demand curve shift to D’$ and the exchange rate rises.
An increase in the demand for US dollar will cause the demand curve to shift to D’$ and the exchange rate increases. Increase in exchange rate means that more rupees are required to buy one US dollar. Fall in the value of Indian rupee in terms of foreign currency is called depreciation.  In this case, domestic currency is less valuable.

Similarly, an increase in the supply of US dollars will cause the supply curve shift to S’$ and exchange rate falls to R. In this case, rupee cost of US dollar is decreasing and the Indian rupee is said to be appreciating. Rise in the value of rupee in terms of foreign currency is called appreciation. In this case, domestic currency is more valuable.







Types of exchange rate systems

The determination of foreign exchange depends upon specific international arrangement of procedure to determine the exchange rate of one country vis-à-vis others.


Fixed exchange rate systems

Under this system, exchange rate is officially declared and it is fixed. Only a very small deviation from this value is possible. A typical fixed exchange rate system was associated with the Gold Standard Systems of 1880 – 1914.
Under the Gold Standard Systems, value of each currency was fixed in terms of gold and hence, the exchange rate was fixed according to the gold value of currencies that have to be exchanged. This was referred to as mint par value of exchange.
For example, if one Indian Rupee is exchangeable for 125 grams of fine gold and the US dollar for 25 grams of fine gold, then one Rupee is equal to 125/25 = 5 US dollars. So, the price is fixed at Re.1=$5.

Adjustable Peg System

Since the gold standard failed to automatically correct the disequilibrium in countries’ balance of payments, an alternate system of fixed exchange rate called Breton Woods system was established in 1944.

Under this arrangement, the US dollar was made directly convertible into gold at a fixed price. Member countries fixed their exchange rates as against the dollar.

The Breton Woods system was an adjustable peg system. The member countries were required to fix the parity of their currencies with gold. A change in the parity was possible only through a direction from the IMF. This system is modified version of fixed exchange rate system but the role of gold as ultimate unit of parity was preeminent.

Advantages of fixed exchange rate system

1. Fixed exchange rates ensure that major economic disturbances which will weaken the economic policies of member countries.
2. Fixed exchange rates contribute to the coordination of macro policies of countries in an interdependent world economy.
3.  Fixed exchange rates are more conducive to expansion of world trade as they prevent risk and uncertainty in transactions.

Flexible exchange rates system:

Flexible exchange rates point to an extreme situation where there is no intervention by central banks.  The foreign exchange market is busy at all times by changes in the exchange rates. In this system exchange rate is determined by the interaction of demand for and supply of foreign exchange.

Advantages of flexible exchange rate system

1. Flexible exchange rates eliminate the need for central banks to hold international reserves.
2. Flexible exchange rates are helpful to do away with barrier to trade and capital movements.
3.  Flexible exchange rates enhances the efficiency in the economy by achieving optimum resources allocation.

Operation of foreign exchange market

Foreign exchange markets could be studied in terms of period of transaction carried out. If the operation is of daily nature, it is called current market or spot market. On the other hand, market for foreign exchange for future delivery is known as forward market.

Spot market for foreign exchange: Spot rate of foreign exchange is used for current and daily transactions. The strength of the domestic currency with respect to all of the home country’s trading partners is measured by the average relative strength of the home country’s currency. It is known as Effective Exchange Rate (EER). Since the effect of price changes is not eliminated, it is also called as Nominal Effective Exchange Rate (NEER).
If the domestic country (India) has ‘n’ trading partners, then
NEER = 



Forward market for foreign exchange: Most of the international transactions are signed one day and the actual transactions take place at a much later date. In the forward market, payments are made on the basis of as and when the actual transactions take place. This is done in order to hedge against (avoid) risks.

A forward contract is entered into for two reasons.
One is to minimize the risk of loss due to adverse change in exchange  or two, to earn profit that may arise due to change in exchange rates. 

Difference Between Fixed Exchange Rate System and Flexible Exchange Rate System

Economics notes-Consumer Equilibrium


2. Consumer Equilibrium and Demand


Utility: It is the want-satisfying power of a commodity. According to Cardinal Approach, utility can be measured in cardinal numbers, such as 1,2,3 and 4.

Total utility: It is the total satisfaction derived from the consumption of a given units of a good.

Average utility: It is utility per unit of the good. It is calculated by dividing the total utility by the number of units consumed.

Marginal utility: It is the addition to the total utility derived from the consumption of an additional unit of the good.

Law of Diminishing Marginal Utility: According to this Law, as more units of a good are consumed continuously and in standard units, the marginal utility derived from the consumption of every additional unit will keep diminishing.

Consumer Equilibrium
Consumer equilibrium is defined as the situation in which a consumer’s utility is maximized and from which he has no tendency to move.
Consumer equilibrium can be analysed in terms of a single commodity and many commodities as well.
In case of a single commodity, a consumer is said to be in equilibrium when the price of the good is equal to the marginal utility derived from a good divided by the marginal utility of a rupee.
The most important assumption of this analysis is that Marginal utility of a rupee is standard (constant).
Marginal utility of a rupee: It is defined as the additional utility that a rupee spent will give to a consumer. A consumer will always have the idea of marginal utility of a rupee whenever he spends a rupee.
For example, if a rupee can buy an ice cream or a candy or a biscuit and if any of the above goods will give the consumer 4 utils, then the marginal utility of a rupee is said to be 4 utils. A consumer will always look for at least 4 utils whenever he spends a rupee.

Let marginal utility of a rupee is 4 utils. The consumer wants to buy orange and the price of an orange is Rs. 4.

Marginal utility of the consumer is given below.
Units of orange purchased

Due to the Law of Diminishing Marginal Utility, the marginal utility will keep falling. However, the consumer has to decide about how many units of orange he should purchase so that his total utility is maximized.
MU of a rupee is 4 utils and the price of an orange is Rs.4. Therefore, it has given him Rs.5 worth of utility (MU of 20 utils/Price of orange). So, he will purchase the first unit.
The second unit of orange gives him utility equal to Rs.4.5. Since he pays only Rs.4 for the second unit, he will buy the second unit also.
The third unit of orange gives him utility equal to Rs.4 which is equal to what he has paid. So, he will purchase the third unit as well.

However, if he goes for the fourth unit, he gets utility equal to Rs.2.5. Since what he pays (Rs.4) is more than what he gets in terms of rupee (Rs.2.5), he will not buy the fourth unit.

Thus, a consumer is in equilibrium where
Price of X = Marginal Utility of X/Marginal Utility of a rupee
Px = MUX/MURe













Consumer Equilibrium: Two goods (or several goods case)
Similar to the single good case, a consumer will reach equilibrium in case of two (or several) goods in the same way. Since
Px = MUX/MURe for good X and PY = MUY/MURe for good Y, then the equilibrium condition can be stated as follows.
MURe = MUX/PX = MUY/PY

This can be explained with the help of the following schedule.

A consumer has Rs.88 with him. He wants to purchase good X and good Y with his money. The market price of X and Y per unit is Rs.8. the marginal utility schedule of goods X and Y are given below.
Units of good

In case of two goods, a consumer strikes equilibrium when
MUX/ PX = MUY/ PY
OR
MUX/ MUY = PX/ PY
In this case, PX and PY are Rs.8 per unit so that equilibrium will b arrived at when MUX = MUY
or when MUX/ MUY = 1.
The equilibrium occurs when the consumer buys 8 units of good X and 3 units of good Y.

His total utility will be 424 utils from good X and 100 utils from good Y, thus totaling 524 utils.

If he chooses any other combination of goods X and Y in order to maximize his total utility, then it will be either his money is not completely spent or he cannot afford to buy that combination because it is beyond his budget.
