My favorite textbook covers business cycle theory toward the end of the book (the last four chapters) precisely because that theory is controversial. I believe it is better to introduce students to economics with topics about which there is more of a professional consensus. In chapter two of the book, I include a table of propositions to which most economists subscribe, based on various polls of the profession. Here is the list, together with the percentage of economists who agree:
- A ceiling on rents reduces the quantity and quality of housing available. (93%)
- Tariffs and import quotas usually reduce general economic welfare. (93%)
- Flexible and floating exchange rates offer an effective international monetary arrangement. (90%)
- Fiscal policy (e.g., tax cut and/or government expenditure increase) has a significant stimulative impact on a less than fully employed economy. (90%)
- The United States should not restrict employers from outsourcing work to foreign countries. (90%)
- The United States should eliminate agricultural subsidies. (85%)
- Local and state governments should eliminate subsidies to professional sports franchises. (85%)
- If the federal budget is to be balanced, it should be done over the business cycle rather than yearly. (85%)
- The gap between Social Security funds and expenditures will become unsustainably large within the next fifty years if current policies remain unchanged. (85%)
- Cash payments increase the welfare of recipients to a greater degree than do transfers-in-kind of equal cash value. (84%)
- A large federal budget deficit has an adverse effect on the economy. (83%)
- A minimum wage increases unemployment among young and unskilled workers. (79%)
- The government should restructure the welfare system along the lines of a “negative income tax.” (79%)
- Effluent taxes and marketable pollution permits represent a better approach to pollution control than imposition of pollution ceilings. (78%)
If we could get the American public to endorse all these propositions, I am sure their leaders would quickly follow, and public policy would be much improved. That is why economics education is so important.
Note that the proposition about fiscal policy (#4) does not distinguish between taxes and spending as the best tool for purposes of macro stabilization. Maybe that question should be added in a future poll. I doubt, however, that the answer would make it onto this list of widely agreed upon propositions.
