Have you seen MM Singh's Oxford D.Phil Thesis. I did. There is no mathematics, no statistics, no theory, simple tables all copied from Government of India publication. There is only one conclusion that in future engineering exports will be important( at that time India used to export only tea and jute). This is the knowledge of MM Singh. Those who do PhD in economics from the West knows nothing about the real world. Several Professors from Harvard were recruited by Yeltsin in 1992 after the destruction of the Soviet Union. Within three months they had destroyed the economy of Russia. Similarly this gang MM Singh, Montek Aluwala, Chidambaram are destroying India.
