Economics in One Page 经济学的基本原理

leave a comment »

  “经济学最迷人的地方就在于她的基本原理是如此的简单,一页纸就能写下,任何人都可以理解,但很少人能做到。”

  上面这句话是著名的经济、统计学者Milton Friedman的名言。虽然这句话里所包含的原则被人们广为接受,但是似乎没有什么人真正去尝试用一页纸来概括经济学。Forecasts & Strategies的编辑Mark Skousen大约是一个愿意吃螃蟹的人。

Economics in One Page

by Mark Skousen

1. Self-interest: The desire of bettering our condition comes with us from the womb and never leaves till we go into the grave (Adam Smith). No one spends someone else’s money as carefully as he spends his own.

2. Economic growth: The key to a higher standard of living is to expand savings, capital formation, education, and technology.

3. Trade: In all voluntary exchanges, where accurate information is known, both the buyer and seller gain; therefore, an increase in trade between individuals, groups, or nations benefits both parties.

4. Competition: Given the universal existence of limited resources and unlimited wants, competition exists in all societies and cannot be abolished by government edict.

5. Cooperation: Since most individuals are not self-sufficient, and almost all natural resources must be transformed in order to become usable, individuals—laborers, landlords, capitalists, and entrepreneurs—must work together to produce valuable goods and services.

6. Division of labor and comparative advantage: Differences in talents, intelligence, knowledge, and property lead to specialization and comparative advantage by each individual, firm, and nation.

7. Dispersion of knowledge: Information about market behavior is so diverse and ubiquitous that it cannot be captured and calculated by a central authority.

8. Profit and loss: Profit and loss are the market mechanisms that guide what should and should not be produced over the long run.

9. Opportunity cost: Given the limitations of time and resources, there are always trade-offs in life. If you want to do something, you must give up other things you may wish to do. The price you pay to engage in one activity is equal to the cost of other activities you have forgone.

10. Price theory: Prices are determined by the subjective valuations of buyers (demand) and sellers (supply), not by any objective cost of production; the higher the price, the smaller the quantity purchasers will be willing to buy and the larger the quantity sellers will be willing to offer for sale.

11. Causality: For every cause there is an effect. Actions taken by individuals, firms, and governments have an impact on other actors in the economy that may be predictable, although the level of predictability depends on the complexity of the actions involved.

12. Uncertainty: There is always a degree of risk and uncertainty about the future because people are often reevaluating, learning from their mistakes, and changing their minds, thus making it difficult to predict their behavior in the future.

13. Labor economics: Higher wages can only be achieved in the long run by greater productivity, i.e., applying more capital investment per worker; chronic unemployment is caused by government fixing wage rates above equilibrium market levels.

14. Government controls: Price-rent-wage controls may benefit some individuals and groups, but not society as a whole; ultimately, they create shortages, black markets, and a deterioration of quality and services. There is no such thing as a free lunch.

15. Money: Deliberate attempts to depreciate the nation’s currency, artificially lower interest rates, and engage in easy money policies inevitably lead to inflation, boom-bust cycles, and economic crisis. The market, not the state, should determine money and credit.

16. Public finance: In all public enterprises, in order to maintain a high degree of efficiency and good management, market principles should be adopted whenever possible: (1) Government should try to do only what private enterprise cannot do; government should not engage in businesses that private enterprise can do better; (2) government should live within its means; (3) cost-benefit analysis: marginal benefits should exceed marginal costs; and (4) the accountability principle: those who benefit from a service should pay for the service.
