Economics:10 Hours for 4-year University Economics

 <<10 Hours for 4-year University Economics>> is written by Toshihiro Ihori, which is an immensely great book for beginners to learn Economics. Of course, it is impossible to learn it within just 10 hours. However, you can have a better understanding of different economic concepts and terms like GDP, Supply and Demand, Profit Maximization etc, which is definitely much better than a textbook.

What is Economics?
  Actually, it means the deal between the economic agent(individuals, enterprises, and government...) and market(products, services, money...).Let's take some examples:
1.a customer buys an apple from a supermarket，it is a deal.
2.the government buys notes from a financial institution, it is a deal.
3.a firm buys stocks from the stock market, it is a deal.

  With the above matters in mind, it is obvious that economics permeate into our daily life and is around every corner of the world.

The concept of Perfect Competition
  Basically, Perfect Competition is buyers and sellers who are under the same conditions. In a perfectly competitive market, the amount of supply and demand is identical, which means the enterprises cannot set the price for their products themselves, fixed price is offered by the market, and therefore the profit is almost zero for companies. Undeniably, it is something that you should make every effort to avoid it if you want to make a profit for yourself. The more you can avoid, the more you can earn. The first thing you should do is focusing on the supply and demand.

One famous concept--- Prisoner's Dilemma
I guess many people have heard this term before despite that they never learn economics. To put it simply, it means that two(or more than two)person are skeptical of each other in a certain situation. For instance:
  There is 2 person who joins a game. Each person has two same choices and can only choose ONE option.
  A. Get $100 to self.
  B. Give $300 to another person.

  so, there are 4 combinations of the results of this game:

  1.both of them cooperate with each other, get $300  together.
  2. A give but B don't, A: $0         B:$400
  3.B give but A don't, A: $   400        B:$0
  4.both of them don't cooperate with each other,get$100 together

  From the above results, apparently, cooperation can provide them with the highest profit. However, Greed and suspicion are human nature when it comes to cooperation. People usually look for the biggest benefit but ignore the biggest drawback for them. If you are an entrepreneur, it is the thing that you should bear in mind, thinking about it deeply.

Of course, in this book, there are still many concepts about economics. If you are a beginner interested in economics, Don't miss this book!😋（But only Chinese and Japanese Version are available😫
