经济essay这么写就对了！

临近考试，刷完经济Essay，拿着完全看不懂的essay mark scheme，小伙伴们是不是又感到脑壳疼！

只有按照CIE评分要求答卷的孩子才能把有限的考试时间都花在刀刃上，收获每一个得分点。

在讲解之前，小编首先强调这样两个原则：

1.请仔细读题！

请明确读懂题目要求后再动笔！不按照题目要求写的内容都会是零分！不按照考试要求写的每个字都是在浪费时间！不是写满了试卷就能得分。

2.请运用经济的知识点答题！

小编只想说不运用知识点的答卷都是耍流氓！

下面我们用一篇经典的PED大题例文

为大家讲解分部解决最头疼的12分的essay

首段请用总起句明确表述整段内容。

2.Strengths of the PED: 2分

Elastic agriculture goods: a small decrease in the price will cause a large increase in the quantity demanded (Qd), and an increase in total revenue (TR)
Inelastic agriculture goods: price, Qd, TR

请通过画图或者举例，让解释内容更充实！

3. Weaknesses of the PED: 2分

Accuracy of calculation.
e.g. Errors, omission, out of date data.
The PED of agriculture goods may change.
e.g. Due to advertising, the demand for green crops has changed from elastic to relatively inelastic.

P3

Discuss how producers use YED to increase total revenue.

1.Income elasticity would inform the producer of the appropriate goods to produce as incomes change.

2.Strengths of the YED: 2分

Income increase: switch to plant agriculture goods with positive elasticities.
e.g. Fine wheat
Income decrease: switch to plant agriculture products with negative elasticities.
e.g. Poor quality wheat.

3.Weaknesses of the YED: 2分

P4

Evaluation 4分

Whether an understanding of price elasticity of demand is of more benefit to a producer of agricultural goods than an understanding of income elasticity of demand depends on the factors:

1. Factor 1: the stability of economic trend. 2分

If the economic trend is unstable.
e.g. Because of the long planting cycle of agricultural products, the unstable economic environment will make the crops face different economic environments when they harvest. Therefore, PED methods can better adapt to the changing economic environment by changing the price.
If the economic trend keeps constant.
e.g. Changing the production strategy can better serve the long-term development of producers and let them experience the benefits of production earlier. Thus, it is better to choose the YED methods.

2.Factor 2: Time period. 2分

If producers want to see the increasing total revenue in the short term.
e.g., 试试自己进行解释 … PED
If the producer pays attention to long-term strategic development and has sufficient funds to adjust the strategy.
e.g.试试自己进行解释 … YED

P5

Conclusion 1分

In reality，producers always hope to adjust the production or sales strategy to obtain higher total revenue in the changing economic environment at this moment. Thus, I think an understanding of the PED method may better.

以上P4内容最多可得4分。Conclusion总有1分，大家一定不要忘了总结哦！
