This paper aims at measuring the key factors based on theory and practice associated with effective SBRs for 20 sub-Saharan African countries over the period 1970-2005.The 20 SSA countries were scored over time on the basis of these factors and a composite SBR time series was calculated for each country. The findings are that first, higher scores are associated with faster growth ; secondly, the new measures correlate well with other governance indicators; and thirdly, they correlate with more operational investment climate data, such as fewer procedures when trading goods and services.
