“…A number of points need to be noted. First, it seems impossible to settle the choice between absolute and relative measures of concentration on a priori grounds alone (Needham 1978:122-131) or in isolation (compare Leach 1992). *(27) Arguments for the superiority of absolute rather than relative measures are commonplace (Leach 1992) but, unfortunately, inconclusive.…”

“…time since the Du Plessis study. This is necessary in view of suggestions by Leach (1992) that earlier findings relating to the level of concentration and upward trends in concentration were incorrect. Now, with a comprehensive set of internationally accepted measures of concentration, a more complete picture of concentration in South Africa can be compiled.…”

“…Therefore the Gini coefficient -a relative measure of concentrationhas proved to be the most frequently applied measure of industrial concentration in South Africa. Recently Leach (1992b) argued strongly for two other measures, viz. an absolute measure, the occupancy count (the number of firms accounting for a given percentage of industry sales, as used by Reekie), and the little used Rosenbluth index, a summary-measure of concentration.…”

Problem statement:The main purpose of the study was to explore the levels of concentration in Zimbabwe's grain-milling industry during period . The study could not be extended to periods after 2005 because the situation in the country had become economically chaotic. Approach: The methodology adopted involved the calculation of the concentration indices such as the Herfindall-Hirschman index, Hannah and Kay index, the Entropy index and the Four-Firm Concentration ratio. Results: The study revealed that liberalisation of the industry reduced seller concentration levels. The response to deregulation in this particular sector confirms the theoretical expectation that liberalisation promotes competition and reduces market power of existing firms, which is also consistent with the world-wide trends. Conclusion: The policies adopted at the inception of Economic Structural Adjustment Programmed (ESAP) should be pursued more vigorously to create a manufacturing base which is open to competition and which is insulated from adverse effects of possible manipulation by a few large firms. Policy should be aimed at maintaining affordability of the basic commodities to the consumers as well as ensuring viability to the manufacturers. With high levels of industrial concentration, producers are able to operate at a higher-cost system without losing market share, but this is to the detriment of the consumers.
