之前的推送我们讲了A2大题的题型：新考纲下A2经济Essay题型整理 (微观)新考纲下A2经济Essay题型整理 (宏观)今天我们来讲一下答题结构。

Intro (AO1)Intro部分写题目中key terms的定义和基础知识。我们按章节来过一下每个知识点对应的

AO1.1. Consumer theory- Evaluate whethermarginal utility theorycan fully explain the link between the changing price of a good and quantity demanded of that good.

AO1: MU, TU, diminishing MU, consumer equilibrium (Utility approach)- Evaluate the use ofindifference curve analysisto derive the demand curve for a normal good and the demand curve for an inferior good.

AO1: IC, BL, consumer equilibrium (IC approach)

2. Market structure- The model ofperfect competitionis the ideal form of market structure because it is the mostefficient. With the help of diagrams, evaluate this statement.

AO1: PC (features), Efficiency (PE, AE, DE)

*如果题目里出现了efficient/resources allocation这些词，那Efficiency是一定要定义的。

3. Market failure- With the help of a diagram, assess the view that government intervention can be used successfully to correctmarket failurecaused bypositive externalities.

AO1: AE, positive externalities, market failure (DWL)*如果题目只考了externality对应的market failure, 那只需要定义AE. 但是必须解释清楚为什么externality会导致DWL.

4. Labour market- The introduction of atrade unioninto a perfectly competitivelabour marketwill always lead to higher wage levels and a higher level of unemployment. With the help of a diagram, evaluate this statement.

AO1: MRP, labour supply, TU*所有labour market的题，都必须先写MRP和labour supply，再解释wage rate determination

5. Policies- With the help of a diagram, assess the effectiveness ofgovernment policieswhich might be used to reducecost-push inflation.

AO1: any two policy instruments, cost-push inflation (meaning, causes and consequences)

* 题目只出现了一个policy aim, 除了这个aim本身的定义之外, 对应的causes和consequences也是需要写的。这两部分在考试的时候非常容易遗漏, 大家要重视。

- An increase in a government’sbudget surpluswill increaseunemploymentin the short run but it will make it easier to control abalance of payments deficit on the current accountin the long run. Evaluate this statement.

AO1: budget surplus, unemployment (3 types), CAD*这里题目考了2个aims，因此只需要解释terms即可，不用写causes和consequences还有一个需要强调的就是Policy的题很多key terms是大家在AS学的，定义部分要去看AS的教科书。

6. Standard of livingAssess the impact ofinternational aidon thestandard of livinginlow-income countries.

AO1: SoL, features of LIC, aid

7. Globalisation- To what extent do you agree with the view thatglobalisationbenefitshigh-income countriesat the expense oflow-income countries?

AO1: globalisation, features of HIC, LIC

Body (AO2+AO3)Body部分，简单来说就是回答题目问题 (Content) + Evaluation- Expenditure-reducing policies will reduce a balance of payments deficit but will also cause significant unemployment. Evaluate this statement.

大家答题的时候可以按照这个结构来：

R1: Expenditure-reducing policies (ERP) will reduce a balance of payments deficit

EV1: ERP willnotreduce a balance of payments deficit

R2: ERP causes significant unemployment

EV2: ERPdoes not causesignificant unemployment

考试的时候写作结构是非常重要的。每一个段落都应该有明确的内容。我建议大家在考试的时候先按照上面的格式写一下plan，再去答题。有些时候题目可以能有三个requirements，答题的时候每一个部分都要涉及，不然就会扣分。

- Central banks can control the money supply. An increase in the money supply will cause inflation, therefore central banks can control inflation. Evaluate this statement.

R1: Central banks can control the money supply

EV1: Central banks can't control the money supply

R2: An increase in the money supply will cause inflation

EV2: An increase in the money supply will not cause inflation

R3: Central banks can control inflation

EV3: Central banks can't control inflation

这里R1R2R3漏掉一个，都有可能扣分。

在不知道mark scheme长啥样的情况下，建议大家都写上去。对于比较的题目，正确的结构是先回答各自的内容，再进行比较。

- Evaluate the view that monopolistically competitive firms will always charge lower prices and operate more efficiently than a monopoly firm.

R1: price and efficiency under monopolistic competition

R2: price and efficiency under monopoly firm

R3: mc charges lower price and operate more efficient than monopolist
