ALevel经济考试中需求与供应的知识点

2020-08-13 14:54:52 905人已读 分享到

  很多想要往金融、经济政治等方向发展的同学在选择ALevel课程的过程中,一般都会选择经济学科。但是ALevel经济备考的难度不小,如何备考经济成了很多人头疼的地方,下面就为大家分享ALevel经济考试中需求与供应的知识点!

  今天我们复习AS经济第二章第一部分的知识点:Demand and supply

  本章一共有三个考点:

  Demand and Supply

  Function of price

  Consumer surplus and Producer surplus

  这一章频繁出现在data和essay的a问,同学们经常会出现知识点都会但是写不了高分的情况,这篇文章能很好的解决大家的问题。

  2.1 Demand and supply

  Frequently asked topics

  Explain factors affecting demand and supply

  Discuss how business could increase demand

  不止一次看到考生这么回答问题:Increase of taste will increase demand. 在考试中,这是不得分的。当题目要求回答影响demand或者supply的因素时,一定要写出背后的原因。

  举例:Due to advertising, if a good becomes more desirable to consumers, consumers are more willing and able to pay the good at a given quantity, this will increase demand and demand curve will shift up.

  对于影响demand的因素,price of complements/substitutes是考试的重点。

  对于影响supply的因素,除了cost of production以外,大家不要忽略了joint supply.

  这个知识点还有一个考点,就是企业如何增加demand? 常见的方式有降价,广告,生产别的产品,出口,同学们要会讨论这些方法的优缺点以及可行性。

  Sample essays

  11S2 Using economic analysis, explain the possible causes of the increase in the sales of electronic goods, such as mp3 players, in recent years.

  04S Increasing raw material costs cause the price of a good to rise. Explain the effect of this price rise for the good on the markets for its substitute and complementary goods.

  15W1 Discuss the policies that businesses might adopt to maintain sales when incomes are falling and consider which is most likely to be successful.

  2.2 Function of price

  Frequently asked topics

  Explain equilibrium and disequilibrium

  Explain change in equilibrium

  Explain function of price (rationing and allocating)

  Discuss limitations of price mechanism (Market failure)


ALevel经济考试中需求与供应的知识点


  这个知识点有三种考题。

  第一种是解释market equilibrium/disequilibrium,同学们需要知道当Demand或者Supply发生变化的时候,新的equilibrium是如何形成的。

  第二种是解释function of price。常考的是rationing 和allocating.

  第三种是解释price mechanism的优缺点,这里的知识点等同于market economy的优缺点。优点是增加competition,满足消费者的需求。缺点是merit/demerit goods 以及public goods。

  Sample essays

  14S2 Explain the meaning of the term ‘equilibrium price and quantity’ in the market for a good or service and show how a new equilibrium is established when there is an increase in demand.

  10S1 ‘A free market price operates as a rationing and allocating mechanism.’ Explain how it does this.

  10W1 Discuss the importance of price in the effective operation of a mixed economy.

  2.3 Consumer surplus and Producer surplus

  Frequently asked topics

  Explain consumer/producer surplus

  Explain changes of consumer/producer surplus

  Welfare的考题,CAIE的考试官特别喜欢考查PED。对于Consumer surplus,大家一定要知道elastic/inelastic demand对应的Consumer surplus是不同的。同理,在supply发生改变的情况下,consumer surplus的改变同样取决于PED。无论题目里有没有提及PED,在写这类文章的时候PED是必须要考虑的。

  Sample essays

  10S2 Using a normal demand curve, explain how consumer surplus occurs.

  12W3 Explain, with the aid of a diagram, what changes will alter the amount of consumer surplus available from the consumption of a good.

  09S1 Explain, with the aid of a diagram, how consumer surplus will be affected by the introduction of an indirect tax.

  以上就是小编为大家带来的ALevel经济考试中需求与供应的知识点,希望考生们在备考中重视起来,除此之外,大家也要在平时多多积累词汇,打好备考技巧的基础。如果想要获取更多alevel报名费用、alevel考试分数等更多信息,大家可以线上咨询我们或继续关注网站更新的文章!
