Grain price stabilization in India: Evaluation of policy alternatives

Stabilization of prices is an important element of food policy in India as in most other countries — both developing and eveloped. However, since the magnitude of grain stocks held for this purpose as well as the costs of physical storage have become prohibitively high, there is now a need for finding cost-effective alternatives including non interventionist and market-oriented methods for price stabilization. In this paper we consider the case of rice and wheat which are staple foodgrains in India. We make a comparison between alternative price stabilization policies including that of holding buffer stocks in terms of their impact on domestic price stability, producer and consumer welfare and government costs. A multi-market equilibrium framework is used where private storage, consumption, supply and prices of rice and wheat are determined simultaneously. Indian exports and imports are assumed to affect world prices. The alternative price stabilizing mechanisms are ranked according to both the criteria, welfare and price stability achieved. The main findings are as follows. The ranking of alternatives varies with the criterion used. Greater price stability need not necessarily imply greater welfare. The option of variable levies on private external trade turns out to be the most inexpensive and that of domestic buffer stocks the costliest in achieving price stability. Further, the efficacy of buffer stocks and subsidy to private storage in stabilizing prices is lower under free trade as compared to the case where the economy is closed to private external trade.

Bidding off the wall in common value auctions

This paper examines the practice of phantom bidding in common value auctions with asymmetric information. Unlike in private value auctions it is very difficult to profit from phantom bidding even if the auctioneer observes the number of interested bidders. We find that the auctioneer is worse off submitting low bids or mixing between his participation strategies. Phantom bidding can generate higher revenues if a single bidder with a high value estimate is likely to be present at the auction. Systematic observation of an isolated high estimate requires negative correlation across bidders’ information that is atypical in a common value environment.

Market information and channel price structure

An analytical model is developed that considers the effect of demand information, and the precision with which demand forecasts are made, on channel profitability. Different channel price structures such as Stackelberg and Vertically integrated are considered and comparisons are made of the impact of information precision on channel profits under each structure. Other demand factors such as brand substitutability and share of base level demand are also included in the analysis, and the interaction of information and demand effects is examined. An empirical study is carried out using a sample of firms based in Hong Kong and support is found for the model propositions.
