What does the U.S. Energy Policy Act of 2005 and its mandatory doubling of renewable fuel additives by 2012 have to do with access to finance? A recent paper uses the sudden increase in demand for U.S. corn, the primary input for ethanol production, as an external shock to see how access to finance affected corn producers in the U.S. It shows that productivity increased after 2005 in corn production as opposed to soybean production and more in counties with better access to finance. Now, just imagine the effect in developing countries!
