Improving Econ 101
We teachers of introductory economics can and should explain where and why economists disagree. That is part of helping students develop their critical thinking skills. But I doubt students are in a position to try to evaluate the competing empirical work that shapes the differing views.
In the end, introductory economics is just that: an introduction to the economist's way of thinking. That means giving students basic concepts--comparative advantage, supply and demand, market efficiency and market failure--that will make them more perceptive readers of the newspaper.
