For such a market to exist, then we specialize in Bay the production

must be the presence of five important conditions. First of all, the number of buyers and zellers must be so large that it is not possible for one buyer or seller to influence the price. The fact in that if there are only a few buyers or sellers, it is possible for one buyer to restrain from buying and this will cause demand to drop and con- sequently bringing a drop in the price. On the other hand, a seller may reduce his supply of the commodity, by putting out a smaller quantity for sale, and in this way he will be able to cause the price of the commodity to ries. But if there are many buyers and sellers, the behaviour of one buyer or seller does not affect the price of the commodity at all. Besides even if buyers or sal- lere try to join into groupa, this is not quite easy when there are too many of them, and moreover human interests. jusually come into conflict.

Another condition to be taken intc. consideration is that the commodity put ap for sale by one seller must be exac- tly identical to that of the same kind put up for sale by another seller, so that for instance there is only one kind of toothpaste in the market; although the toothpaste is sold by different sho pa it is exactly the same in evary shop. In this way, buyers will not develop any prejudicial preference for one kina instead of another. Thus, whether he buys the toothpaste from A shop or B shop, the toothpaste is the same.

know that this condition only exiata in theory, because we have goods under dif ferent. brands and although they appear to be very close aubstitutes for each other, they are actually dissimilar.

The third condition for a perfect market to sxist is that the buyers mu the sellers must not have any prejudi os against one another. For instance if one buyer decides to buy from only one. particular, shop because both he and the soller go to the same church, then this may cause the

the seller to reduce the pr1- ce. One the other hand, a seller may sell his

goode at different prices to different customera, and when this hap- pena there is no parfect competition. In short, sellers and buyers must not let any influences to affect the pricen of the gooda.

It is also necessary for every Du yer and seller to know exactly what is. happening in the market; both must know the market price. Again, this condi-

tion is difficult to fulfil, becaught

buyers for instance are reluctant to spond their time to find out if the price of a commodity sold by one shop is truly the cheapest. Again, sometim 98, a buyer prefers to pay for a higher price by buying from the shop nearest to his home instead of going to another shop far away, although the price is much cheaper,

The final condition is that the aroduct must be movable, so that any

increase in demana can de met by a pro- portional increase in supply. However, this condition seldom existe, because certain things cannot be transferred. from one place to another Lands and buildings are examples of such things.

In practice it is extremely dif ficult for a market to approach perfec- tion. Commodities are seldom, if ever at all, homogeneous; both buyers and sellers are often full of prejudice, and both are reluctant to compare prio~ es, perhaps because they cannot afford the time. Some buyers are persuaded to believe that higher prices mean that the

commodities are of better quality, and others are willing to pay more if the service. more courteous or the ahop is cleaner than another shop. Sellers on the other hand, may lower the prices for the more friendly cust- omers. Thus, retail marketa especial- ly are far from being perfect. TAS stock exchange, which is a highly org- anized market, however, may be consid ered as one approaching quite close to

DArfect market.

of clothes only, it would mean that we have to rely on the other parts of the world to supply us the other equam lly important commodities to meet our needa. It appears to be all right to have inter-dependent relations among the nations of the world, as justified by the Theory of Comparative Cost, but it would lead to eventual explcita- tion of the weaker countries by the stronger ones. An economically adva- nced country would demand a weaker. country to give more of the latter!! goods in exchange for the goode from the former, knowing that the latter has no choice since it specializes in only one industry, whereas the former specialize in many, and can well af- Ford to stay independent..
