Dani Rodrik is back, and he reignites an old debate with his recent blog post. He asks if high food prices are good or bad for poverty, and answers, “It depends on whether the poor are selling or buying, of course.” Citing a recent paper by Jacob Swinnen, he goes on, “High food prices benefit poor farmers who are net food sellers, and hurt poor food consumers in urban areas. Low food prices have the opposite effects. In each case, the net effect on poverty depends on the balance between these two effects.”
Seems obvious, but not so fast: What if the poor also work for wages and agricultural prices affect labor markets? Sandra Polaski and others have shown that when one incorporates labor market effects of high vs. low agricultural prices, high prices will clearly be better for many developing countries.
