Economic And Publio äffairs (24)

Qusations (1) Discuss the merits and

domerita of the different forma of money that exist in our community.

FARANDEE

Legal tender, or more commonly re- ferred to as cash, and cheques are the two principal forme of money. But i题 recent years, another form of money has been introduced, known as credit carde, These are regarded as money as they gan be used as a medium of exchange as well as a means of deferred payment. Credit cards are in fact proving more popular than cheques in the United States; in Hong Kong their popularity is gradually, Ingressing, but cheques are still the

more popular, compared with credit cardr

For samll payments legal tender is convenient to use and de therefore used by averybody. There are many times during the day when one hae. to, make amall purchases and on such occasions: the dollara and centa in our pocketa are used. Another reason for using then, either in making small or big payments, is the fact that the law hag compelled everybody to accept them in payment of a debt. Thus, no one ban the right to refuse to accept the dol- lars and cents we offer him unless he reasonably suspecta our dollars and cents to be counterfeit.

But it is unsafe to carry legal tender around, especially in large sums, He run the risk of being robbed, or i离 may be that through our plain careless- mess we lose our walleta or purses and so lose our money. Thus, it is often: considered foolish if one carries, a great deal of legal tender on ones body.

Another drawback of legal tender

18 that it takes up a considerable amount of tian to count and check the legal tender especially when we have to buy an expensive.commodity. Businessmen: for that reason have invariably done away with legal tender and use cheques instead whenever a business transaction involves a large sum of money,

mon drawback of legal tender is the fact that our dollar notes get dirty very @asily and quickly. Although this state of affairs may not present an immediate threat to public health, it may. certainly arouse in one an unpleag ant feeling whenever one receives chan- ges from a shabbily-dressed, untidy- looking hawkez

Cheques, on the other hand, are never used when one makes payments of small sume. They become inconvenient, Besides, cheques cost the writer an extra sum of money, for every cheque carries a fixed stamp duty But they are popularly used in business transac tions. Firstly, they save both parties, the buyer and the seller, the time. and effort which are spent, în counting the checking the money when cash is used. It only takes a minute or two to write a cheque, Secondly, they are safe" to carry around, even if they are

bearer cheques, the reason being that if we know our cheques have been lost or stolen or even robbed an immediate phone call to the bank can stop the unlawful bearer from "cashing" the cheque, Thirdly, cheques can be used as a means of deferre red payment. For instance, if the seller. agrees to accept, we can write him a post- ated chequer i.e. a cheque carrying a future date. - Crossed cheques eliminatë any possibility of their being stolen, because when cheques are crossed they cannot be exchanged for cash at the bank by the bearer or anybody. When the bank

But it must be borne in mind that cheques: are, only accepted if the payee agrees and is willing to accept theo. Since they are not legal tender no ored=) átor is legally bound by law to accept them in payment of a debt. This, perhaps is the chief drawback of cheguesa

Credit cards can take the place of cash and cheques. Kost business institu...) tions especially hotels, restaurants and department stores allow their customers to make purchasen and sign for the bills, which at the end of the month are then sent to the customers for payment. Muck smaller then a Hong Kong Idantity Card, a credit card carries the name, signa ture and account number of the customer.") Whenever the customer makee use of the services or buys the goods of the busi- 'ness. Institution that has ingeued him

the card, all he needs to do is to prođ- ace the card to the cashier and sign hia name over the bill. As the name suggesta, a credit card is a form of deferred pay- ment. But credit cards are not issued to everybody; they are only given to those who are, creditworthy; a.e. those who can be relied upon to pay their bills when called upon to do so. Lead- ing hotels like the Ambassador, the Mandarin and the Peninsular have a large number of crdit-card holder.

Queetionı (2) Explain man's wanta, and how they are classified" Do man's wants possen cer tain characteristics? What are they?

Anewest

Man's wanta are classified into two distinct groupe manta primary wanta and man. a secondary wante. By primary wants, we mean man's basic wants such as food, shelter and clothes Other wanta which are less vital and without which. man can still survive, but which have enabled him to live more comfortable and lururi= ously are known as secondary wantes Examples of secondary wants are recreas tions and entertainments.

Man a wants do posses characteris- ties, for instance, most wante are comp etitive. This is shown by the fact that we often have to choose betwen one want and anothery we do realise that: goods and services which satisfy our wants are scarce our wants are many, 80-a choice has always to be made. The way we plan the use of our money or time is a classic example of choice necessitated by acargátyo

Another important characteristle or can's wants is that they tend to increase in number. Each day we find new wante added to what we originally had. tury ago, our ancestors would not be. thinking of needing a washing machine or A television set in the home. Today we do. Secondary wants tend to multiply

with the passage of time. If we bought: a transistor radio yesterday, today we may think of wanting a radiogram, and perhaps later a more expensive. "Hi-Fi? aound system in ons home

Wants are algo generally complemen sry, or joint. For example, records 60 with a radiogram or a gramophone; shut- tlecocks go with racquets. Thus when we buy records; we must also buy a grano- phone, otherwise the records would be. of no use to US.. There must be many A

examples of wants which are complement-' ary. What about typewriters and paper? Bread and butter? Coffee, sugar and milk? Cigarettes and matches?

Wants can also be often fully sat-) isfied. However great our desire to Batisfy a particular need may be, there ? is a limit in our desire to achieve satisfaction. We are ready to sacrifice to obtain a particular need, but there Più also a limit to which we are willing

to sacrifice. Most people, for example, are only too happy to have only one; motoresarS
