The state bank is extending financial accommodation mainly through rediscounts of first class bills of exchange, government securities and such other eligible papers.

(2) Clearing House Service:
Being the holder of the balances of the commercial banks, the state bank is specially qualified to act as a bank of state clearance.
Krick and Klikin mentoined that:
"It is for the central bank to setup an expedition, and economical machinery for the clearance of draft and settlement of internal account."
The bank performs this function for commercial banks. Every bank receives cheques drawn on other banks, because of which every bank becomes creditor or debtor to the other bank or banks. All these cheques are sent to the state bank where it settles all the accounts of the banks by adjusting their debit or credit balances.

(3) Rediscounting bills of Exchange:
Another valuable service performed by the bank is to rediscount bill of exchange. Commercial banks discount bills of exchange of businessmen. Discounting encashment of the bill before it matures, at a certain rate of interest. As a result commercial banks fall short of cash. So they approach the state bank for rediscounting of the same bills.

(4) Cash reserves:
Under banking law, every commercial schedule bank is bound to deposit a certain percentage of all its deposits with the state bank. This service serves many objects.
(i) It provides safety to commercial bank's account holder.
(ii) It makes easy for state bank to control over credit creation.
(iii) These reserves may be used to finance commercial banks in need.

(5) Counseling service:
The state bank offers precious advice and counseling services. In the light of its export opinion and advice commercial banks formulates and read just their policies.

Q.4 What is meant by Rate of Exchange? Describe the factors that affect the rate of Exchange.
Ans: Rate of Exchange: It is defined as:
"The rate of exchange between two countries is the amount o f one currency that will be exchanged for one unit of another currency".
For instance, of $1 can be exchanged for Rs.106, then the rate of exchange between dollar and rupee is $1 = Rs. 106.

Factors Influencing the Exchange Rate:
The market rate of exchange existing on any particular day need not be the same. It is liable to fluctuate. The causes given rise to such fluctuations are as follows:

(1) Trade Factor:
Trade factor relate, to the influences arising from the exports and imports. Suppose the equilibrium rate of exchange between Pakistan and US is $1 = Rs. 150. For some reasons the exports from U.S increase more than the import. That mean Pakistan have to pay more dollar to U.S. the demand for dollar increase and the exchange rate of dollar increase.

(2) Stock exchange factor:
Stock exchange factor relates to the influence arising from granting of loans, repayment of loans, receipt of interest, payment of interest, purchase and sales of foreign securities etc, for e.g. Suppose U.S is granting a loan to Pakistan. The demand for rupees will increases in U.S. The result is the fluctuation of exchange rate in Pakistanis favour.

(i) Banking Factor:
Banking factor relate to the influences arising front the activities of banks such as purchases or sales banker's draft, travelers cheque, arbitrage operations etc. For instance the sale of a draft on a foreign centre creates demand for foreign currency and raise it value. The exchange rate will move in the favour of the foreign currency.

(ii) Currency and credit conditions:
Currency and credit conditions of a country, also influence the rate of exchange. Exchange dealers are always careful to watch the probable trend of the internal and external value of a country's currency. If the total quantity of note-issue is steadily increasing without a corresponding increase in the total volume of goods the result will be inflation.
The increased in price of the commodity will cause a decrease in its exports. An adverse balance of payment position will develop. Such situation induces the exchange dealers to dispose off their stock of home currency relative to its demand thus causing a fluctuation in the rate of exchange unfavourable to the home currency.

(3) Budgetary policies of Country:
Budgetary polices of a country will also cause fluctuations in the rate of exchange. Where it appears than the extent of public expenditure is in compatible with the national stock of that currency.

(4) Political and Internal Industrial Situation:
The political conditions and internal industrial situation of country also cause fluctuation in the rate of exchange. A stable government, the stick maintenance of law and order, the protection of property and of the rights of owners of wealth will all induce an inflow of foreign capital, either for interest gaining purpose or for safety. The adverse situation will induce the withdrawal of capital and cause the unfavourable exchange rate. While stable political and industrial conditions will cause the fluctuation of exchange rate in favour of a country.

2. Attempt any THREE part questions. All question carry equal marks.
i) Briefly describe the Degrees of Elasticity of Demand.
Ans: Ans: Degrees of Elasticity of Demand show the limit of elasticity of demand means how much change may come in demand of goods due to change in price or other factors.
  • Perfectly Elastic Demand: Perfectly elastic demand is said to happen when a little change in price leads to an infinite change in quantity demanded.
  • Perfectly Inelastic Demand
  • Unitary Elastic Demand
  • Relatively Elastic Demand
  • Relatively Inelastic Demand

ii) Draw Revenue curves under Imperfect market.
Ans: Revenue Curve under Imperfect Competition:
When a firm is working under conditions of monopoly or imperfect competition. its demand curve or AR curve is less than perfectly elastic. In other words, the demand/AR curve has a negative slope and the MR curve lies below it. This is because the monopolist seller ordinarily has to accept a lower price for his product, as he increases his sales.
Under imperfect competition conditions. total revenue increases at a diminishing rate. It becomes maximum and then begins to decline.
DOWNWARD SLOPING REVENUE CURVES

iii) Differentiate between Change in Supply and Change in Quantity Supplied with the tool of diagram.
Ans: Ans: In economics, supply is defined as the amount of a good or service that producers are willing and able to sell at each possible price.
Change In supply occurs due to changes in costs and incentives that change how much a producer can and will produce at a given price. Simply we can say that change in supply due to change in factors other than price.
Whereas Change In quantity supply means change in supply of goods due to change in retail price of goods.
Change in Supply Vs. Change in Quantity Supplied
A change in supply is not the same as a change in quantity supplied.


iv) Explain the concept of MONOPOLY and Mention its types.
Ans: Monopoly is a market situation in which there is only one seller of a product with barriers to entry of others. There are following types of Monopoly:

1. Natural Monopoly:
Some countries due to their physical location and climatic condition can produce a large proportion of the total global production of a product and supply it in the international market at their demanded price.
For example, South Africa has natural monopoly on gold and Brazil on coffee.

2. Legal Monopoly:
When a firm discover a new technique of production or invent a new machine it gets registered its ownership right or we can say that firm has copyright to produce such product and other firms don't have this called legal monopoly.
For example Government Arm factory who have the right to produce arms for defense force.

3. Social Monopoly:
When a firm has right to produce and work for the protection of Public interest for example Sui Gas Company has given rights to produce and distribute natural gas in Pakistan. The company is enjoying a social monopoly.

4. Implied Monopoly:
When some firms or group of business make alliance or pool or cartel to control production of some specific product and make barrier for new companies to enter in their business that is called implied monopoly.

v) Explain the Law of Diminishing Marginal Utility with the help of schedule and diagram.
Ans: Law of Diminishing Marginal Utility:
According to the Law of Diminishing Marginal Utility, marginal utility of a good diminishes as an individual consumes more units of a good. In other words, as a consumer takes more units of a good, the extra utility or satisfaction that he derives from an extra unit of the good goes on falling.
Marshal defines that "The additional benefit which a person derives from a given increase of his stock of a thing diminishes with every increase in the stock that he already has."
Schedule:
 Cups Of Tea  Total Utility  Marginal Utility

MACRO ECONOMICS   (Marks: 15)

3. Answer any THREE part questions. All question carry equal marks:
i) Differentiate between PI and DPI.
Ans: Personal Income (PI):
PI stand for Personal income which is actually received by individuals or households of a country during a year. Deductions are not deducted from this income or salary.
For example before deduction of tax and social security from salary is called personal income.

Disposable Personal income (DPI):
Disposable personal income is that income which is actually available to individuals or households for spending or consumption. We can also say it take home salary or income of individual. Several deductions such as taxes etc are deducted from salary.
DPI = Personal Income - Personal direct taxes

ii) Differentiate between Balance of Trade and Balance of Payments.
Ans: Balance of Trade:
The difference between aggregate value of exports and imports is called balance of trade. If the export value of a country is more than import value, it will be favorable balance of trade. Contrary If export is less than import, it will be unfavorable or negative balance of trade.

Balance of Payment:
Balance of payment gives a comprehensive picture of a country. It includes not only exports and imports but also includes the non-commodity items. These items are services rendered by shipping, insurance. banking companies, debt repayment and a payment of interest and expenditures done by tourist. The difference between receipts and payments are called balance of payment. If receipts are more than payments it will be favorable. contrary if the receipts are less than payments, it will be negative balance of payment.

iii) Mention the characteristics of a good tax system.
Ans: 1. Productivity or Fiscal Adequacy:
An important principle of a good tax system for a developing country is that it should yield adequate amount of resources for the Government so that it should be able to perform its increasing welfare and developmental activities.

2. Diversity:

A good tax system should follow the principle of diversity. This implies that there should not be a single or a few taxes from which Government seeks to raise large revenue. This is because if a Government tries to get large revenue from a single tax or few taxes, it will have to raise the rates of taxation too high.

3. Taxation as in Instrument of Economic Growth:
In a developing economy such as ours, taxation should serve as an instrument of economic growth. Economic growth is primarily a function of rate of capital formation.

iv) Explain Y = C + I G + (X -M).
Ans: Ans: This equation shows the National Income of a country during a year.
Y = Income
C = Consumption
G = Government Expenditures
X = Export
M= Import
The equation shows that national income of any country depends upon the consumption, government expenditures, and the difference of Export and import means balance of trade. Therefore national income includes the GDP and GNP and overall personal income of a country.

v) Explain the concept of Direct and Indirect Taxes with the help of examples.
Ans: A direct tax is paid by an individual or organization to the entity that levied the tax. Direct taxes include income taxes, property taxes, and taxes on assets. There are also indirect taxes, such as sales taxes, wherein a tax is levied on the seller but paid by the buyer.

SECTION 'C' (DETAILED-ANSWER QUESTIONS)

4. Answer any ONE part question. All question carry equal marks:
i) Explain the concept of Market Price with the help of schedule and diagram.
Ans: The market price is the current price at which an asset or service can be bought or sold. The market price of an asset or service is determined by the forces of supply and demand. The price at which quantity supplied equals quantity demanded is the market price.
The market price is used to calculate consumer and economic surplus. Consumer surplus refers to the difference hetween the highest price a consumer is willing to pay for a good and the actual price they do pay for the good, or the market price.
Market Price depends on the demand of goods and services that are sold in market. Therefore to understand the combination of price and demand of goods, the law of demand explained by economic experts. Law of supply is also the determinant of Market price but here is we are explaining the important factor of market price which is law of demand.

Law of Demand:
The law of demand describes the relationship between the quantity demanded and the price of a product.
It states that the demand for a product decreases with increase in its price and vice versa. while other factors are at constant. Therefore, there is an inverse relationship between the price and quantity demanded of a product.

Schedule:
 Table - 1: Individual Demand Schedule
 Price Of A (Per kg in )  Quantity Demand (per week in kgs)
 10 15
 15 10
 20 8
 25 4
 30 2

Diagram:

The above schedule and diagram show that as the price decreases, the quantity demand increases.

ii) Describe the merits and demerits of International Trade.
Ans: Merits of International Trade:
(i) Optimal use of natural resources:
International trade helps each country to make optimum use of its natural resources. Each country can concentrate on production of those goods for which its resources are best suited. Wastage of resources is avoided.

(ii) Availability of all types of goods:
It enables a country to obtain goods which it cannot produce or which it is not producing due to higher costs, by importing from other countries at lower costs.

(iii) Specialization:
Foreign trade leads to specialization and encourages production of different goods in different countries. Goods can be produced at a comparatively low cost due to advantages of division of labour.

Demerits of International Trade:
(i) Impediment in the Development of Home Industries:
International trade has an adverse effect on the development of home industries. It poses a threat to the survival of infant industries at home. Due to foreign competition and unrestricted imports, the upcoming industries in the country may collapse.

(ii) Economic Dependence:
The underdeveloped countries have to depend upon the developed ones for their economic development. Such reliance often leads to economic exploitation. For instance, most of the underdeveloped countries in Africa and Asia have been exploited by European countries.

(iii) Political Dependence:
International trade often encourages subjugation and slavery. It impairs economic independence which endangers political dependence. For example, the Britishers came to India as traders and ultimately ruled over India for a very long time.
