曼昆经济学读后感范文

  从2013到2016,用了三年时间断断续续的读了曼昆的微观经济学和宏观经济学,还跟了coursera上面的两个课程。读完两本厚厚的教材,学了N个概念和模型,最后回过头来问自己:我到底在这里面学到了什么?

曼昆经济学读后感范文

  总体而言,学完这两本书之后对于经济学有一定的系统的认识,这一点是经济学通俗读物万万比不了的。当然,后者的行文更容易理解,一般也都是大牛撰写,但相比之下我个人更喜欢有组织有结构的去学习某一个领域的知识——尤其是在新进入一个领域的时候。

  回想当时之所以想学这两本书,最主要的目的还是为了增加自己对于商业的理解和所谓的business sense。然而,看完之后似乎对于这个目的并没有太大的帮助。毕竟经济学是一门科学,而商业思维更多是实践,是不断在实践中总结和提炼的经验(以及直觉)。

  刨除具体的概念不谈,两本书中的一些原则和行文逻辑对我帮助最大。最下面附上了了曼昆书中的10个经济原则,以及我认为4个(标红部分)对于商业生活有帮助的原则。附上几点自己的理解:

  人们总是面临选择权衡;某件事情的成本是你放弃了什么:这两点可以结合起来看,意即每时每刻我们都在做出选择(是约会还是看书,去哪里约会,看哪本书…),而选择的成本不仅仅是在该选择上花费了多少,还有你没做什么(如果看书的话固然很好,但是代价就是不去约会而注孤生…)。

  理性人会思考边际(请注意不是“只思考边际”):比如景区的矿泉水卖10块钱一瓶——虽然一瓶矿泉水的成本(包括制造成本、销售成本、租金等)肯定不到十块钱,但是作为理性人,你会比较此时的口渴程度和10块钱,进而选择买或者不买。

  贸易使得每个人生活的更好:现在的大公司(比如微软),哪个没有几个合作伙伴——这样双方都可以将精力放在自己擅长的方面,通过贸易的方式让双方员工都获益。

  Ten Principles of EcnomicsHow

  People Make Decisions

  1.People face tradeoffs:

  To get one thing, you have to give up something else.

  2.The cost of something is what you give up to get it:

  Making a decision requires comparing the costs and benefits of alternative courses of action. The cost of one option is not how much it will cost in dollar terms, but rather the value of your second best alternative.

  3.Rational people think at the margin:

  People make decisions by comparing the marginal benefit with the marginal cost. For example, you might buy one cup of coffee in the morning because it helps you start the day, but you might not buy a second cup because this gives you no extra benefit (and costs another $3)。

  4. People respond to incentives: Behaviour changes when costs or benefits change.How People Interact

  5.Trade can make everyone better off:

  Trade allows people to specialise in what they do best. By trading, each person can then buy a variety of goods or services.

  6. Markets are usually a good way to organise economic activity.

  7. Governments can sometimes improve market outcomes: Sometimes a market may fail to allocate resources efficiently, and government regulation can be used to improve the outcome.How the Economy Works

  8. A country‘s standard of living depends on its ability to produce goods and services.

  9. Prices rise when the government prints too much money: Printing money causes inflation. When a government prints money, the quantity of money increases and each unit of money therefore becomes less valuable. As a result, more money is required to buy goods and services.

  10. Society faces a short-run tradeoff between inflation and unemployment: Reducing inflation often causes a temporary rise in unemployment. This tradeoff is the key to understanding the short-run effects of changes in taxes, government spending and monetary policy (Phillips curve).
