This paper evaluates the role of food inventories or buffer stocks in stabi
lizing prices of foodgrains in India when private external trade in grain i
s liberalized. The model adopts a multi-market equilibrium framework with t
he direction of trade determined endogenously. World prices are assumed to
be sensitive to the amount traded by India (the 'large country' effect). Th
e simulation results demonstrate that holding foodgrain inventories is an i
nefficient mechanism for stabilizing domestic prices under liberalized trad
e. Variable levies/ subsidies on trade appear to be more cost effective. Fr
eeing of trade lowers domestic price variability even though world prices a
re more volatile. (C) 2001 Elsevier Science B.V. All rights reserved.
