Milanovic: Bob Allen's new "poverty machine" and its implications

Bob Allen's new "poverty machine" and its implications by Branko Milanovic

But, intriguingly, Allen’s work in this area has also implications for his work in another area: the origins of the Industrial Revolution. As is well-known, Bob is the originator of the hypothesis of High Wage Economy (HWE), an argument that the Industrial Revolution was driven by high cost of labor in England (and low cost of energy) which made the substitution of labor by capital profitable. This was most famously seen in the evolution of the welfare ratios (nominal wages divided by the cost of the subsistence basket) for North-West Europe vs. Italy vs. China/India. While all three welfare ratios were about equal in the 15th century, they diverged afterwards with North European being much higher and China/India’s welfare rations plummeting. Allen saw in that divergence the origin (and not the effect) of the Industrial Revolution.

Now, with the poverty lines that are subscripted for place and time, what we see to be a welfare ratio from the worker’s perspective is no longer the same thing as the cost of that worker to a capitalist. The new methodology introduces a wedge between what is the worker's welfare and what is the cost of labor for the capitalist. This is most obviously seen in Allen’s former and new results for Russia. With the same basket across all countries (the earlier approach) Russian welfare ratio during most of the 19th century was 2; with a climate/country specific baskets, the welfare ratio is around 1 (that is, is much lower because of high requirements imposed by a cold climate).

But note that the cost of that worker to a Russian capitalist is still twice as high as the cost of an equivalent worker (at the same subsistence) in India. When we now draw the welfare ratios using Allen’s new methodology, we have to explicitly state that they reflect welfare ratios from the worker’s perspective, not the cost of labor. The implication of this wedge is that, following Allen’s own HWE hypothesis, introduction of machines is --everything else being the same—more profitable in the North than in the South.

If that’s the case, then a geographically-determined explanation for the Industrial Revolution suddenly looks more plausible than before. So, I thought, perhaps one (unintended) effect of Bob’s new and much improved methodology is to help the geographical explanations for the rise of the West.
