The present study uses Hall’s approach to test for market power in the Kazakh grain processing industry using regional level panel data covered over the period 2000-2011. This study also tests and compares the degree of competition in three sub-periods, 2000-2004, 2004-2007 and 2008-2011. The results suggest that there is no evidence for the existence of oligopsony power in the time period from 2000 to 2011. However, the statistically significant parameters indicating market power was found for the period 2008-2011, which can be explained as a consequence of the government intervention on grain market.
