News Flash: Economists Agree

Greg Mankiw:
The recent debate over the stimulus bill has lead some observers to think that economists are hopelessly divided on issues of public policy. That is true regarding business cycle theory and, specifically, the virtues or defects of Keynesian economics. But it is not true more broadly.

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:
  1. A ceiling on rents reduces the quantity and quality of housing available. (93%)
  2. Tariffs and import quotas usually reduce general economic welfare. (93%)
  3. Flexible and floating exchange rates offer an effective international monetary arrangement. (90%)
  4. Fiscal policy (e.g., tax cut and/or government expenditure increase) has a significant stimulative impact on a less than fully employed economy. (90%)
  5. The United States should not restrict employers from outsourcing work to foreign countries. (90%)
  6. The United States should eliminate agricultural subsidies. (85%)
  7. Local and state governments should eliminate subsidies to professional sports franchises. (85%)
  8. If the federal budget is to be balanced, it should be done over the business cycle rather than yearly. (85%)
  9. The gap between Social Security funds and expenditures will become unsustainably large within the next fifty years if current policies remain unchanged. (85%)
  10. Cash payments increase the welfare of recipients to a greater degree than do transfers-in-kind of equal cash value. (84%)
  11. A large federal budget deficit has an adverse effect on the economy. (83%)
  12. A minimum wage increases unemployment among young and unskilled workers. (79%)
  13. The government should restructure the welfare system along the lines of a “negative income tax.” (79%)
  14. 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.

And that is a big part of why I wanted to become an economist.

Interestingly, economists largely agree on the need for a large economic stimulus.

Economists from both the left and right are on the same page; the only opposition stems from shameless Republicans in Congress who want to play partisan politics in a time of national crisis.

In fact, many economists think the stimulus may not be large enough.

I'd also say we need a greater respect for education in general and a return to rationality over ideology.

There's a scientific consensus on global warming, yet some continue to deny that. It's rather shocking.

Going even further, there's near unanimity among scientists about the validity of evolution, and yet many people refuse to accept that. Evolution is not a theory, it is a fact.

But we have one party, the Republican party, that enshrines ignorance and makes it the centerpiece of their platform.
