South African trade policy matters Trade performance and trade policy

South African trade policy has exerted a major influence on the composition and aggregate growth of trade. In the Apartheid period, trade protection seriously impeded both exports and imports, and the economy depended on favorable global commodity price trends to avoid running into an external constraint. South Africa developed a comparative advantage in capital-intensive primary and manufactured commodities partly because of its natural resource endowments but also because the pattern of protection was particularly detrimental to exports of non-commodity manufactured goods. High and opaque tariffs seriously impeded export growth. When global commodity markets were weak, in combination with declining gold exports, this seriously constrained aggregate growth and dulled the response of exports to the weaker rand in the late 1980s. On the other hand, surcharges were effective in reducing imports. By contrast, trade liberalization in the 1990s not only increased imports but, by reducing both input costs and the relative profitability of domestic sales, also boosted exports. The growth in non-commodity manufactured sectoral exports as a result of liberalization was actually faster than sectoral imports. This evidence suggests that additional trade liberalization could well be part of the strategy to enhance export diversification. It points to the importance of policies that afford South African firms with access to inputs at world prices as well as a competitive real exchange rate.

Trade and the Structure of South African Production, 1984-97

With the onset of trade liberalisation, fears have been raised concerning the impact of trade on manufacturing output, employment and growth. Using an input–output methodology, this article decomposes South African output growth between 1984 and 1997 into final demand expansion, trade flows and technology. There are two main findings. First, trade liberalisation has not deindustrialised the manufacturing sector. Although import penetration has risen, export growth has matched and exceeded the potential import-induced losses in domestic production. South Africas response thus conforms closely to international evidence. Secondly, a combination of strong growth in capital-intensive exports and import penetration in ultra-labour-intensive sectors has aided the structural shift in production towards capital-intensive sectors. However, capital-biased supply-side policies, as well as endemic problems within ultra-labour-intensive sectors, suggest that domestic factors and not trade liberalisation lie behind this shift.

Us Trade and Wages: The Misleading Implications of Conventional Trade Theory

Conventional trade theory, which combines the Heckscher-Ohlin theory and the Stolper-Samuelson theorem, implies that expanded trade between developed and developing countries will increase wage equality in the former. This theory is widely applied. It serves as the basis for estimating the impact of trade on wages using two-sector simulation models and the net factor content of trade. It leads naturally to the presumption that the rapid growth and declining relative prices of US manufactured imports from developing countries since the 1990s have been a powerful source of increased US wage inequality. In this study we present evidence that suggests the presumption is not warranted. We highlight the sensitivity of conventional theory to the assumption of incomplete specialization and find evidence that is not consistent with it. Since 1987, although US domestic relative effective prices in industries with relatively high shares of manufactured goods imports from developing countries have declined, effective unskilled worker-weighted prices have actually risen relative to skilled worker-weighted prices. If anything, this suggests pressures for increased wage equality. Also in apparent contradiction to theory, the (six-digit North American Industry Classification System [NAICS]) US manufacturing industries with high shares of manufactured imports from developing countries are actually more skill intensive than the industries with high shares of imports from developed countries. Finally, applying a two-stage regression procedure, we find that developing-country import price changes have not mandated increased US wage inequality. While these results conflict with standard theory, they are easily explained if the United States and developing countries have specialized in products and tasks that are highly imperfect substitutes. If this is the case, the impact of increased trade with developing countries on US wage inequality is far more muted than standard theory suggests. Also methodologies such as the net factor content of trade using US production coefficients and simulation models assuming perfect substitution between imports and domestic products could be highly misleading.

The Impact of Chinese Import Penetration on the South African Manufacturing Sector

Abstract This article uses a Chenery-type decomposition and econometric estimation to evaluate the impact of Chinese trade on production and employment in South African manufacturing from 1992 to 2010. The results suggest that increased import penetration from China caused South African manufacturing output to be 5 per cent lower in 2010 than it otherwise would have been. The estimated reduction of total employment in manufacturing as a result of trade with China is larger – in 2010 about 8 per cent – because the declines in output were concentrated on labour-intensive industries and because the increase in imports raised labour productivity within industries.

AGOA Rules: The Intended and Unintended Consequences of Special Fabric Provisions

While exports of clothing from Africa to the United States responded impressively to the preferences they were granted under the African Growth and Opportunity Act (AGOA), this performance was not accompanied by some of the more dynamic benefi ts that might have been hoped for. Benefi ciary countries still do not have viable internationally competitive industries that could survive without the preferences, or that have diversifi ed horizontally into new products and markets or vertically into greater domestic value addition. In this paper we demonstrate that this outcome is a predictable consequence of incentives under the Multi-Fiber Arrangement (MFA) quotas and the AGOA trade preferences. Th e paper fi rst extends standard trade models and predicts that, in equilibrium, the MFA encouraged exports of low quality and low value added products by AGOA countries and higher quality and higher value added products by quotaconstrained countries. AGOA preferences further encourage specialization in clothing products with high fabric cost shares in the least developed countries receiving the preference. Th e paper then tests these theoretical predictions using diff erence-in-diff erences estimations by looking at changes in the value-added and fabric intensity of AGOA apparel exports in response to the ending of the MFA in January 2005 and the granting of AGOA preferences from 2001. Th e results show that MFA quotas and AGOA preferences caused least developed AGOA recipients to specialize in fabricintensive products with low value added as well as rising fabric content.

How Integrated is SADC? Trends in Intra-Regional and Extra-Regional Trade Flows and Policy

Do Southern African Development Community countries trade enough with each other and with the rest of the world? Although its share of world trade has fallen, appropriate benchmarking shows that, controlling for gross domestic product and other characteristics, Southern African Development Community countries have experienced an increase in openness that is comparable to other developing countries. Once market size and geography are taken into account, trade between Southern African Development Community countries is actually high. Southern African Development Community countries also trade more products with each other than they do with the rest of the world. In this sense, and contrary to stylized fears, the Southern African Development Community region is quite integrated. Although the Southern African Development Community has reduced its tariffs, the structure remains complex and could be lowered on intermediates. Other impediments make it costly and difficult to move goods, but are at levels that are comparable with countries at similar levels of development. Although this may be surprising, there is still scope for improvement and the disadvantageous geography of the Southern African Development Community makes it important for other trade impediments to be reduced.

Is Africa Integrating? Evidence from Product Markets

This paper presents a price-based assessment of product market integration in Africa using disaggregated retail prices for 91 products and 12 African cities from 1991 to 2008. We find evidence of substantial deviations from the law of one price − product price differences between the cities averaged 76% over the period – a result that is consistent with the presence of large barriers to trade in the continent. Mean price differences across cities fell by close to a quarter over the period, but the decline was concentrated in the early 1990s with little progress subsequently, despite the regional trade policies implemented by the countries. Gravity-style estimates reveal that reductions in external tariffs and global trends towards price convergence in the early 1990s are the key contributors to the trend in price integration amongst the African cities.

A strategic view of South African trade policy in relation to the future global trading environment

This paper puts forward a strategic view of what South African trade policy should be doing in relation to the future global trading environment. The future is uncertain, but if the past is prologue, South African trade policy needs to be positioned for a continuation of the commodity cycle, and to exploit markets in emerging economies, including Africa, more fully. Simultaneously, it needs policies to spur labour-intensive services and manufacturing exports, both because these will be needed if commodity markets are less robust and because of their employment-creating potential. South Africas current strategy, however, is inflexible, heavily focused on domestic concerns and is in danger of placing South African exporters at a disadvantage in accessing the growing emerging economies. It also gives rise to an inherent tension between the interests of South Africa and the African region in trade negotiations. Having as the central tenet of trade policy a commitment to deal with tariffs on a case-by-case basis will not serve South Africa well in the global economy that is likely to emerge over the next 15 years. A simpler tariff structure would facilitate the conclusion of free trade agreements and actually make industrial policy more effective.

Revisiting wage subsidies: How pro-poor is a South African wage subsidy likely to be?

Wage subsidies have been used in both developed and developing countries to raise employment. After a decade of deliberation, the South African Government recently announced the introduction of a wage subsidy scheme. Given the intrinsic link between unemployment and poverty in South Africa, the belief is that a wage subsidy programme sufficient in scope will also make inroads into poverty. However, the way in which jobs are distributed among poor and non-poor jobseekers is crucial. Our general equilibrium microsimulation model confirms the expectation that a higher wage elasticity of labour demand is associated with larger reductions in poverty. We also find that a greater proportion of new jobs accrue to poor jobseekers when the elasticity is high. While youth-targeting does not improve the poverty-reducing effect of the policy, sectors such as textiles, accommodation, and construction services with their pro-poor employment profiles are good candidates for targeting.

Dataset on retail outlet product prices for Botswana, Lesotho and South Africa

The data presented in this article are related to the research article entitled “Closer monetary union and product market integration in emerging economies: Evidence from the Common Monetary Area in Southern Africa” (M. A. Nchake, L. Edwards, N. Rankin, 2017) [1]. This article describes the monthly retail product prices used in the compilation of the consumer price index of Lesotho, South Africa and Botswana, and collected by the statistical offices in the respective countries. The data are provided at the product level and vary across cities and across time. Each individual product has information on the date (month and year), city, product and unit codes, units of measurements and, in some cases, brand name of that product. The data is made publicly available to enable replication analysis or to extend on the existing results.
