What I want you to learn

One of our colleagues from another department was asking what we try to teach students in our core courses. Here is what I told him I want students to take away from econ 151:

Long-term economic growth is the consequence of division of labor, specialization, and exchange.

Just because both parties benefit from a transaction, they don't necessarily benefit equally. The distribution of the benefits of specialization and exchange depends on the relative power of the parties.

People's behavior is the consequence of both their preferences and their constraints. If you don't understand another's behavior, don't be too quick to attribute it to preferences or values. Look also at the choices they have. On the other side, don't attribute all behavior to economic incentives. Incentives matter, but values and preferences matter too--sometimes more.

Economic efficiency is desirable, but it is not the only thing we're looking for. We also want distributive justice, ecological sustainability, and caring relationships within the economy. Sometimes there are tradeoffs among these different goals. However, it is good also to look for ways to achieve more than one of them simultaneously.

When people disagree about public policy, it is usually not because they want to achieve different goals. More often they disagree about the analysis: that is, what policies will bring about the effects they desire. But these theoretical disagreements often have value judgments at bottom: What is a good theory? What drives human behavior? Can other people be trusted? It is here that "worldviews" matter.

Too long an answer, but as some great writer said, I don't have enough time to give you a short one.

Dear Prof. Tiemstra,

Thank you for your thoughtful entry!

You wrote:

"Economic efficiency is desirable, but it is not the only thing we're looking for. We also want distributive justice, ecological sustainability, and caring relationships within the economy."

My question is: You seem still to put much emphasis on economic efficiency, even primacy. Why do you do that?

Why not say without an apology to anyone:

"Caring relationships (with man and God) are most desirable. To reach this goal we want also, as a means, to look at distributive justice, ecological sustainability, and economic efficiency."

Or as Alfred Marhall put it:

"Men, even now, are capable of much more unselfish service than they generally render: and the supreme aim of the economist is to discover how this latent social asset can be developed most quickly, and turned to account most wisely."
