The prevalence of imperfect price transmission in the agricultural food markets continues to be an importantpolicy concern for most countries in Africa. Motivated by the coexistence of soaring food prices and highdomestic food production, this article investigates the performance of wholesale white maize markets inEthiopia during the post-agricultural market liberalization period. The presence of price manipulation inthe grain market structure has important welfare implications as it impedes the full transmission of pricereductions and increases among marketing intermediaries. Results indicate that regional maize marketsadjusted more quickly to price decreases than price increases to the central Addis Ababa wholesale maizemarket prices, suggesting the absence of positive asymmetric price transmission. Our findings are in contrastwith existing studies conducted in southern, western and eastern Africa major food commodity markets.
