Some of the things that are most interesting to international political economy scholars such as meself are notoriously difficult to measure. To take one example, there’s a lot of muttering in the US and elsewhere about international trade, whether multilateral and bilateral trade deals are good or bad for the US economy, and so on (these debates also have close equivalents in Europe and elsewhere). But how to cut through the hype to figure out whether or not there is a real likelihood of change in the current regime or not? The usual approach is to look for an indicator variable of some variety that will allow you to track underlying processes that you can’t directly measure. I think I’ve found one – and it’s _at least_ as good as the Economist’s famous Big Mac index for figuring out shifts in PPP. My claim is that the degree of rhetorical overkill in Jagdish Bhagwati’s op-ed fulminations on trade is a very good indicator of what the free trade establishment actually thinks about the underlying risks or threats to the existing regime, and (to the extent that this establishment is politically plugged in) a plausible leading indicator of what’s likely to happen in the future. I’ll endeavour to test this hypothesis by keeping track of the Bhagwati Blood Pressure Index (or BBPI) over a period of time, and testing whether it maps well onto the expected outcomes.
Bhagwati’s piece in today’s FT is a good place to start. Those unfamiliar with his writing style might think that language such as “faintly ludicrous,” “denigration of freer trade,” “witless fear of trade,” and “disturbingly protectionist” indicates a BBPI that is alarmingly high, both for free trade and for Professor Bhagwati. Comparative analysis with previous op-eds and writings would suggest, however, that these criticisms are almost genial by historical standards; at worst they’re love taps. By my reading, the BBPI has dropped quite significantly since mid 2007 or so, suggesting that the free trade establishment believes that the current fervor over free trade is froth that will mostly disappear after the primary season. On the evidence of this article, we may expect the BBPI to drop still further if Barack Obama is elected President (one presumes that Bhagwati believes Austan Goolsbee’s representations to the Canadian government), but to rise substantially in the unlikely event that Hillary Clinton snatches the crown. Also of interest is the evidence that the article provides on the mental modelling processes that underlie these empirical predictions:
whereas Mr Obama’s economist is Austan Goolsbee, a brilliant Massachusetts Institute of Technology PhD at Chicago Business School and a valuable source of free-trade advice over almost a decade, Mrs Clinton’s campaign boasts of no professional economist of high repute. Instead, her trade advisers are reputed to be largely from the pro-union, anti-globalisation Economic Policy Institute and the AFL-CIO union federation.
Clearly then, your soundness on trade depends on the extent to which your campaign employs economists whom Professor Bhagwati approves of. I suspect that Hillary’s campaign is doubly damned because it’s supported by Paul Krugman (whom professor Bhagwati condescendingly refers to as an apostate ‘former student’). Nor had I hitherto realized that the economists of the ‘pro-union, anti-globalisation Economic Policy Institute’ were unprofessional economists of little repute; silly me.
Update: Megan McArdle suggests that a basket of pundits would be preferable.
