Price transmission studies have become increasingly important in Sub Sahara Africaover the last two decades because of their application in assessing the impact of themarket reforms policies embarked upon by the region’s governments between the mid1980s and early 1990s. In this study, a meta database obtained from 45 pricetransmission studies published between 1978 and 2011, is used to provide an overallassessment of the potential impact of selected, study-specific attributes on estimatedprice transmission coefficients and in identifying asymmetric price transmission.Despite the large dispersion of estimated price transmission coefficients 2.5% - 94.2%,the mean coefficient of 32.2% is an overall assessment that the extent of pricetransmission in SSA is comparatively low. The predicted impacts of the study-specificattributes on the price transmission coefficients, and on the likelihood of the primarystudies to report asymmetric price transmission however differ consistently across theattributes, and provide in general evidence on the critical role such attributes play indetermining price transmission results and their implications for policy formulation.Therefore, future research on price transmission should carefully account for theimpact of study-specific attributes in their results.
