The second graph sets out the ratio between GDP per work in industry and GDP per worker in agriculture for Thailand, Indonesia, Malaysia and the Philippines. Thailand has the highest ratio for the entire period (1980 to 2007) though it comes close to Indonesia at the beginning and the end. Interestingly the ratio in Thailand declines steadily from 2000 to 2007, partly due to an significant increase in agricultural productivity (from about US$600 per worker to about US$1600 per worker). Is this increase in agricultural productivity (and the narrowing of the gap between agricultural and industrial productivity) a product of Thaksin-era policies? Has the expansion of contract farming increased agricultural productivity?
