Abstract

Price transmission studies have become increasingly important in Sub Sahara Africa over the last two decades because of their application in assessing the impact of the market reforms policies embarked upon by the region’s governments between the mid 1980s and early 1990s. In this study, a meta database obtained from 45 price transmission studies published between 1978 and 2011, is used to provide an overall assessment of the potential impact of selected, study-specific attributes on estimated price 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 price transmission in SSA is comparatively low. The predicted impacts of the study-specific attributes on the price transmission coefficients, and on the likelihood of the primary studies to report asymmetric price transmission however differ consistently across the attributes, and provide in general evidence on the critical role such attributes play in determining price transmission results and their implications for policy formulation. Therefore, future research on price transmission should carefully account for the impact of study-specific attributes in their results.
