Perhaps this should be entitled "The Perils of Market Efficiency" instead, because this is more about market liberalization than improved productivity.
Although this article highlights some of the consequences of market liberalization, I think it's dangerously to extrapolate this case more broadly. First, structural readjustment programs took place in sub-Saharan countries that lacked necessary markets, transit infrastructure, and other prerequisites for private business growth. This differs from in the United States, where such infrastructure is substantially more mature. Second, many of these countries lack sufficient crop diversification, which when coupled with limited purchasing power, exacerbates famine during droughts.
