FIRM SIZE AND EFFICIENCY IN THE SOUTH AFRICAN MOTOR VEHICLE INDUSTRY *

The South African motor vehicle industry has historically been considered a critical industry in the South African economy and the target of numerous government policies designed to protect it and/or increase its international competitiveness. This study examines the cost performance of firms in this industry according to their size, using data categorised by output level. The results are consistent with statistically significant economies of scale at the lowest output levels and a cost inefficiency averaging from about seven to nine per cent for all firms. The findings also suggest that all else equal, the smallest firms and the largest firms have lower unit costs than mid-sized firms. While this work suggests that policies that would give incentives for the smallest firms to increase their scale of operations might help to reduce their unit costs, further investigation needs to be done with respect to why firms in the mid-level size categories appear to be less efficient.

INDUSTRY RESPONSES TO THE TOBACCO EXCISE TAX INCREASES IN SOUTH AFRICA

The cigarette manufacturing market in South Africa is highly concentrated, with one company controlling more than 90 per cent of the market. In this paper the retail price of cigarettes is divided into three components: excise tax, sales tax and industry price. After decreasing during the 1970s and 1980s, the real industry price increased substantially during the 1990s. This coincided with sharp increases in the excise tax. The amplified increase in the real retail price of cigarettes decreased aggregate cigarette consumption by about a third. Despite this sharp decline, the cigarette industry substantially enhanced its revenues during the 1990s. However, since 2000 real industry price increases have been comparatively modest.
