In comments responding to my criticisms in this post, Paul of Global Growth Org asked me a series of questions, which I’ll try to answer here.
(i) Which statistic did I mis-represent?
Paul said these WTO statistics provided “clear evidence” that trade liberalisation is increasingly important for poverty reduction. They don’t.
(ii) What developing nation’s industry or service do you think should be protected from competition?
(iia) Who will this benefit?
(iib) How long will they benefit from protectionism?
(iic) Who will this harm?
My point is that these are not questions for me to try to answer, but for people in the countries concerned to answer.
(iii) What benefits do you see in trade-barriers to South-South trade?
Similar potential costs and benefits to the barriers to North-South trade.
(iv) If you accept that a primary cause of poverty is a lack of employable capital, how would you encourage FDI in to Sub-Saharan Africa?
Improve levels of health and education, and improve the access of producers in Africa to regional and global markets through more investment in transport, communications and power. Reduce structural disadvantages in world trade by removing barriers in rich country markets and eliminating harmful export subsidies. That kind of thing. I’d like to see the progress that has been made to improve democratic institutions and reduce corruption continued for its own sake, but I’m not convinced that this will increase investment significantly because I don’t think it’s the main constraint at the moment.
(v) How much extra capital inflows would Africa receive if it increased its engagement in world trade by 1%?
Gosh, I don’t know - have you got a figure in mind by any chance? Bear in mind that to answer that question you would have to be sure you were looking at extra capital flows that were caused by higher trade, as opposed to higher trade caused by extra capital flows or higher trade and capital flows caused by something else, e.g. improving institutions or better infrastructure.
(va) Do you think $70bn of private sector capital inflows would serve to alleviate poverty in Africa?
That depends. Private sector inflows should generally be good to some extent, but some investments are more pro-poor than others. And if capital inflows are merely feeding a speculative bubble that eventually bursts and hits the poor hard, then that’s no good at all.
(vi) Do you deny that open markets encourage increased trade?
They may well be correlated, but that could be because they’ve both been caused by something else, e.g. economic growth. This is quite plausible; as Dani Rodrik says, the consistent pattern is that countries reduce trade barriers as they grow, not before they grow.
And other factors are critically important too. As Dollar and Kraay say here (although in support of really terrible piece of analysis), “differences in countries’ trade shares reflect their geographic characteristics (for example, countries that are small and close to major markets tend to trade more than countries that are large or remote) to a much greater extent than their trade policy decisions”.
(vii) Do you deny that trade growth generally reduces poverty and brings prosperity?
The argument here seems to be that growth in trade volumes causes higher GDP growth which causes reductions in poverty. Well, it’s not clear that trade does ’cause’ growth in this way - rather, growth in trade volumes seems to be an outcome of other factors. Rodrik and Rigobon say here (pages 6 and 7) that trade ‘openness’ (trade as a % of GDP) doesn’t seem to be good for GDP once you control for geography and institutions, but GDP growth is good for trade growth - another example of how an apparent correlation may not reflect the causation you think it does.
Low income countries are actually more ‘open’ in trade terms (again, ‘openness’ referring to %trade/GDP) than rich countries, but the idea that “the richest countries are those who trade the most” is still remarkably popular, as this recent post from the consistently wrong Globalization Institute shows.
(viii) Are you opposed to increasing world trade and promoting economic growth in principle?
No. I’m mostly interested in reducing poverty, and growth can be a means to that end.
(ix) How do you think a sovereign nation is forced to liberalise exactly?
Conditionality, as the World Bank itself has admitted. The IMF in particular has long exploited its position as lender of last resort to impose liberalisation conditions on countries which had no other choice but to accept.
(x) Have you noted that most of us free traders advocate the advanced nations of the world unilaterally adopting free trade? That we don’t care much for managed trade as offered by the WTO et al, but we take what we can in terms of market opening where we can?
Your point being?

Overall I would argue against seeing the issues in these extremely general, aggregate terms: even if it were true that trade liberalisation generally caused higher trade volumes (and it’s not clear that it does) and that higher trade volumes generally cause higher growth (and it’s not clear that they do) and that growth was always pro-poor (if it increases inequality, it’s quite possible for it to be anti-poor), then it would not necessarily follow that, say, Mozambique should have removed barriers to the trade in raw cashew nuts. Each situation would be different, and each decision on trade policy should be taken on its own merits.
Secondly, it is extremely important to not confuse correlation with causation. If growth in trade volumes is correlated with growth in GDP, it’s all to easy to simply assume that the GDP growth was caused by by the increase in trade. But there’s two equally plausible explanations - the GDP growth caused the trade growth, or both were caused by something else.
