Conventional wisdom holds that protectionism is counter-cyclic; tariffs, quotas and the like grow during recessions. While that may have been a valid description of the data before the First World War, it is now inaccurate. Since the Second World War, protectionism has not been counter-cyclic; tariffs and non-tariff barriers simply do not rise systematically during downturns. I document this new stylized fact with a panel of data covering over 180 countries and 40 years, using over a dozen measures of protectionism and six of business cycles. I test and reject a number of potential reasons why protectionism is no longer counter-cyclic. A "diagnosis of exclusion" leads me to believe that modern economics may well be responsible for the decline in protectionism's cyclic behavior; economists are more united in their disdain for protectionism than virtually any other concept. This in turn leaves one optimistic that the level of protectionism will continue to decline along with its cyclicality.Keywords: empirical, panel, data, policy, trade, barrier, international, tariff, recession, business cycle.

The BuzzPhysics has quantum mechanics, relativity, and now the Higgs boson. Chemistry has developed the battery, plastics, and radioactivity; modern medicine has given us antibiotics, transplants and vaccination. What has Economics done for humanity lately, if ever? In this paper I argue that perhapsjust perhaps -modern economics is responsible for the decline in protectionism … or at least its (counter-) cyclicality.It is widely accepted that protectionism is counter-cyclic; tariffs, non-tariff barriers and the like are more numerous and/or intense during recessions. Indeed, the entire academic literature, without exception (to the best of my knowledge), agrees that protectionism is counter-cyclic; a review (relegated to the appendix) provides more details.1,2 This paper has a single primary objective: refuting that hypothesis. I wish to establish a new stylized fact; during the post-WW2 era, protectionism has not been counter-cyclic. By way of contrast, there is widespread agreement that protectionism was counter-cyclic before WW1.The secondary goal of this paper is to interpret my new finding; why did the cyclic nature of protectionism change, and what should we make of it? Modern economies differ from those of a century ago in a number of ways. Most counties are now richer, bigger and more open; income and value-added taxes are more important sources of government revenue; many exchange rates now float; the social safety net is larger; production is fragmented across international boundaries; there is more intra-industry trade; and international institutions like the WTO restrict commercial policy. However, in practice none of these things seem to affect the responsiveness of protectionism to the business cycle. That is, the cyclicality of protectionism does not...
