Tyler Cowan says slower growth in India is a troubling sign in 2012, and as significant if not more than the eurozone crisis. A less mentioned and major problem is the low productivity in agriculture, and he points to Japan, Taiwan, and S. Korea where major increases in agricultural productivity preceded successful industrialization. With growing population and continued growth India will be one of the largest economies in the world. The other major problem is shortages of energy supplies and the inability of state owned company, Coal India, to upgrade technology and increase output.
