CQ9棋牌 这篇文章中我将给你一些Essay buff,让你写作弯道超车不是梦!

CQ9棋牌 在解说详细效果前,我们先来看看一篇Essay的基本架构:



With the help of diagram, discuss whether consumers will benefit from the introduction on a product of an effective maximum price.

CQ9棋牌 第一步:要害看法+公式

Relevant definitions(Key terms)+Formula

首先我们识别出题干中的 key terms-maximum price 并对其界说阻拦形貌,形貌完界说后对其condition阻拦形貌。

Define maximum price

CQ9棋牌 Maximum price is the maximum legal price that a seller is allowed to charge for a product.The price is not allowed to rise above this level but it is permitted to fall below it.

The condition for maximum price to be effective

If the maximum price is set above the equilibrium prices, it has no effect,

since the equilibrium remains attainable. It is effective when set below the equilibrium price.

CQ9棋牌 第二步:绘图表+诠释图表

Draw diagram+Explain diagram


Explain the diagram

CQ9棋牌 Here Pe and Qe are the equilibrium price and quantity that would prevail without government regulation.

The government, however, has decided that Pe is too high and mandated that the price can be no higher than a maximum price, denoted by P1.

CQ9棋牌 At this lower price, producers will produce less, and supply will be Q1. Consumers, on the other hand, will demand Q3, so demand exceeds supply, and a shortage Q3-Q1 develops.


Draw diagram+Explain diagram


The beneficial and harmful effects of maximum price

As a result some people gain and lose from price controls. Consumers whocan purchase the product at a lower price are clearly better off, as surplus for them increases measured by rectangle A.

CQ9棋牌 But those who have been rationed out and cannot buy the good are worse off because they lose the surplus measured by triangle B.

The net gain to consumers is the difference between rectangle A and triangle B.

CQ9棋牌 Another major consequence of maximum price, with or without rationing, is the emergence of the black markets. This is a market in which goods are sold illegally at whatever price equates illegal demand and supply.

CQ9棋牌 Black marketers would buy Q1 at the controlled price of P1 paying the amount measured by rectangle E.

They would sell at the price Pb, earning profits shown by the gray area between Pb and P1. The existence of such a market results in all consumers becoming definitely worse off.


CQ9棋牌 Evaluation (Conclusion)

最后诠释consumers 能否benefit存在一些局限性:最低价钱的全体影响取决于固订价钱是低于还是高于市场平衡价钱。


Finally we conclude that overall effect of maximum price depends on whether the price is fixed is below or above the market equilibrium price,

so far the consumer benefit is concerned maximum price can potentially result in an increase in consumer surplus .
