“Economics Is Organized Common Sense” by The Elephant's Child

Economists Craig Newmark and AEI’s Mark Perry dug up Nobel economist Thomas Sargent’s shortest U.S. graduation speech ever. A simple list of twelve valuable economic lessons. The speech was delivered at his undergraduate alma mater University of California at Berkeley, May 16, 2007.

“I remember how happy I felt when I graduated from Berkeley many years ago. But I thought the graduation speeches were long. I will economize on words.”

“Economics is organized common sense. Here is a short list of valuable lessons that our beautiful subject teaches.”

1. Many things that are desirable are not feasible.

2. Individuals and communities face trade-offs.

3. Other people have more information about their abilities, their efforts, and their preferences than you do.

4. Everyone responds to incentives, including people you want to help. That is why social safety nets don’t always end up working as intended.

5. There are tradeoffs between equality and efficiency.

6. In an equilibrium of a game or an economy, people are satisfied with their choices. That is why it is difficult for well-meaning outsiders to change things for better or worse.

7. In the future, you too will respond to incentives. That is why there are some promises that you’d like to make but can’t. No one will believe those promises because they know that later it will not be in your interest to deliver. The lesson here is this: before you make a promise, think about whether you will want to keep it if and when your circumstances change. This is how you earn a reputation.

8. Governments and voters respond to incentives too. That is why governments sometimes default on loans and other promises that they have made.

9. It is feasible for one generation to shift costs to subsequent ones. That is what national government debts and the U.S. social security system do (but not the social security system of Singapore).

10. When a government spends, its citizens eventually pay, either today or tomorrow, either through explicit taxes or implicit ones like inflation.

11. Most people want other people to pay for public goods and government transfers (especially transfers to themselves).

12. Because market prices aggregate traders’ information, it is difficult to forecast stock prices and interest rates and exchange rates.

That is a remarkably valuable short list. Pin it up beside the mirror in your bathroom so you can read it every morning until you know it by heart.

[…] the right-conservative narrative (do we have one?) at all, but we will see. Consider “Economics is Organized Common Sense” which I think is closer to the mark for the right, briefly […]
