Prices, Trade and Why People Care
Posted by Matt Zeitlin on June 15, 2008
Ezra Klein follows up on Dani Rodrik and notes that while trade lowers prices for people who buy things (everyone), for those who make things it can be bad, because it raises the relative price of exports and make them less competitive:
Put broadly, opening ourselves up to trade is really good for people who buy things, and less good for people who make things. Now, a lot of folks both buy and make things, so the story is complicated. But one reason the elite classes are so hegemonically enamored with trade is that they don’t really make anything at all, and so experience none of the downsides of trade. As Dean Baker likes to point out, we’ve structured our trade deals such that unskilled manufacturers face a lot of international competition while reporters, say, face almost none. But if you think about how reporters deal with layoffs and cutbacks — policies pursued, like trade, because they save money and increase efficiencies — you can basically predict how they’d feel about trade if their profession was suddenly outsources to Indian reportage firms.
But while the “elite classes” don’t experience the downside of their exports becoming less competitive, Ezra is conflating what happens to the prices of what people consume (they go down for everyone) and what happens to the jobs and wages when trade is liberalized. There’s some pretty good evidence showing that since liberalized trade lowers prices of non durable consumer goods and since the poor spend a much larger proportion, they benefit disproportionally (”inflation for households in the lowest tenth percentile of income has been 6 percentage points smaller than inflation for the upper tenth percentile over this period.”) If you were Will Wilkinson, you could probably make a Rawlsian argument that liberalizing trade is morally required by the difference principle in light of this analysis. But let’s get back to Ezra’ argument.
The second point, on how people’s personal situations vis a vis trade and international competition affects their view of liberalization, there’s been some pretty good research on this question. Dani Rodrik wrote a paper arguing that, not surprisingly, the more one benefits from trade, or is already better off, the more likely they are to support liberalization:
Preferences over trade are also correlated with the trade exposure of the sector in which an individual is employed: individuals in nontraded sectors tend to be the most pro-trade, while individuals in sectors with a revealed comparative disadvantage are the most protectionist. Third, an individual’s relative economic status, measured in terms of either relative income within each country or self-expressed social status, has a very strong positive association with pro-trade attitudes. Finally, non-economic determinants, in the form of values, identities, and attachments, play an important role in explaining the variation in preferences over trade.
And why this analysis could very much apply to the journalists (and bloggers!), it most notably does not apply to the very economists whose work these advocates and analysts cite. Bryan Caplan points out that economists, despite having high job security, are incredibly open to foreign competition. To crib form him, Dani Rodrik is a Turkish born professor, and the academy is pretty open to foreigners, especially in social science as math-heavy as economics.
I don’t really know what the point of all this is, but it seems interesting and relevant nonetheless
