Buyer Collusion and Efficiency of Government Intervention in Wheat Markets in Northern India: An Asymmetric Structural Auctions Analysis

This article uses auction theory to analyze wholesale markets for wheat in Northern India. This approach enables us to characterize the market in terms of buyer asymmetries, to detect the existence of collusion, and to quantify its impact on market prices. We show that buyer asymmetries exacerbate the downward impact of collusion on prices. The article also considers whether the government paid too much for the wheat it procured at the minimum support price, and shows that for our sample it did not. The article is based on a primary survey of two wholesale markets in North India. Copyright 2004, Oxford University Press.
