干货|A-level经济怎么学？

A Level经济考试既是考核学科知识，

也是考察学生的考试能力，

CA今天给大家介绍的就是exam-smart tips，

帮助大家考试拿高分！

 

Tip 1-事件的影响

纵观整个经济大纲，经常会要求学生评估事件对某一事物的影响。

在解决类似问题的时候，可以参考这些分析范围：

 

Tip 2-集中精力于经济分析

写经济essay的时候，时间总是紧张的。那么知道内容比例的划分就尤为重要，解释content占多少，简洁的explanation占多少。

有一个70/30的原则。举两个例子：

Theory of CA包含很有价值的经济分析，学生应该解释它的假想条件，比较机会成本比率，得出贸易可以获得什么。

Material SOL要求具体的经济分析，包括实际GCP与名义上的GDP数字、收入分配、按PPP计算的GDP。

 

Tip 3-合理性检查

非常有用，但也经常被忽视的一点。意思就是看一下自己的topic sentences，是否用最直接的方式回答了问题。有时候，我们有些段落可能是用来介绍背景信息但却没有直接回答问题。

举个例子

Explain why the price of fuel tends to be more volatile than other secondary products. (10m)

 

Topic Sentence (Version 1): The PED of fuel is affected by a number of factors, including its degree of necessity. Supply of fuel is also affected by a number of different factors.

Topic Sentence (Version 2): Demand for fuel is price-inelastic due to its nature as a necessity. Supply may also fluctuate given unstable conditions in theMiddle East, a major oil producing region. An unstable supply curve coupled with an inelastic demand curve would lead to wide and frequent fluctuations in price.

 

Tip 4-记住内容

学习内容很多的概念时（比如说弹性概念、规模经济、进入壁垒），可以参照一个DDEE的原则保证答案的完整性。

 

• Definitions
• Diagrams
• Explanation
• Examples

这样学习概念更方便记忆，因为之前大家的知识是分段的。

比方说遇到“Differentiate between internal and external economies of scale (10m)”这样的问题，

根据DDEE原则就能立马想出essay结构：

Definition: Internal EOS are reaped due to growth of the firm while external EOS are independent of firm size and are attributed to growth of the industry.

Diagram: Internal EOS is seen diagrammatically as a movement downwards along the long run average cost curve (LRAC) while external EOS manifests as a downward shift of the entire LRAC.

 

Explanation / Examples: Sources of internal EOS include technical, marketing, financial or managerial economies. On the other hand, external EOS takes the form of economies of information, concentration or disintegration.
