South Africa Trade Liberalization and Poverty in a Dynamic Microsimulation CGE Model

South Africa has undergone significant trade liberalization since the end of apartheid. Average protection has fallen while openness has increased. However, economic growth has been insufficient to make inroads into the high unemployment levels. Poverty levels have also risen. The country’s experience presents an interesting challenge for many economists that argue that trade liberalization is pro-poor and pro-growth. This study investigates the short and long term effects of trade liberalization using a dynamic microsimulation computable general equilibrium approach. Trade liberalization has been simulated by a complete removal of all tariffs on imported goods and services, and by a combination of tariff removal and an increase of total factor productivity. The main findings are that a complete tariff removal on imports has negative welfare and poverty reduction impacts in the short run which turns positive in the long term due to the accumulation effects. When the tariff removal simulation is combined with an increase of total factor productivity, the short and long run effects are both positive in terms of welfare and poverty reduction. The mining sector (highest export orientation) is the biggest winner from the reforms while the textiles sector (highest initial tariff rate) is the biggest loser. African and Colored households gain the most in terms of welfare and numbers being pulled out of absolute poverty by trade liberalization.Sequential dynamic CGE, microsimulation, trade liberalization, total factor productivity, poverty, welfare, growth, South Africa

Poverty and inequality effects of a high growth scenario in South Africa: A dynamic microsimulation CGE analysis

The debate about the consequences of economic growth on poverty and welfare was recently rekindled in South Africa by announcements that the government would be targeting a sustainable growth rate of 6 percent per annum under the Accelerated and Shared Growth Initiative for South Africa (ASGISA). This paper uses a sequential dynamic computable general equilibrium model linked to a nationally representative household survey to assess the poverty and economic consequences of a higher economic growth scenario. The main findings are that higher economic growth induces reductions in poverty both in the short and long run. It enhances capital accumulation, particularly in the agriculture and textiles sectors. An interesting observation is that the Mining industry benefits the least from a high economic growth scenario. However, this is not related to domestic savings/investment. Mining is strongly dependent on foreign investments and the industry return to capital is less profitable to domestic institutions, particularly households and this is what explains the lower benefits to the sector. African and Coloured households reap most of the benefits, with greater gains among urban unskilled dwellers. These findings suggest that lifting of growth constraints rather than macroeconomic stimulation would induce higher growth with the resulting beneficial effects. Economic growth of the levels simulated does not appear to be inconsistent with macroeconomic balance, as reflected in price stability, balance of payments and sectoral effects.Sequential dynamic CGE, microsimulation, ASGISA, poverty, welfare, growth, South Africa

Does Trade Liberalisation Lead to Poverty Alleviation? a CGE Microsimulation Approach for Zimbabwe

A CGE microsimulation model is used to study the poverty impacts of trade liberalization in Zimbabwe. A sample of 14006 households from a 1995 household survey is individually modeled in a CGE framework. The experiment performed is a 50 percent reduction in all import tariffs. The sectors with the highest initial tariffs are the non-export agriculture sectors and the most export-intensive sectors are found in agriculture and in mining. The halving of tariffs favors export-oriented sectors, mainly in agriculture, whereas industrial sectors are hardest hit by the increased import competition. As agriculture is intensive in unskilled labor and industry is intensive in skilled labor, unskilled wages rise relative to skilled wages. The consumer prices fall and this, together with increased unskilled wages, leads to a fall in poverty. The fall in the price of manufactured food, which is consumed mainly in urban areas, coupled with the large number of unskilled workers in these urban areas, explains why poverty falls more here than in rural Zimbabwe.Computable General Equilibrium, Trade Liberalisation, Microsimulation, Poverty

A multiregion general equilibrium analysis of fiscal consolidation in South Africa:

A multiregion applied general equilibrium model is used to examine the financial interactions among spheres of government in the context of fiscal consolidation. The framework combines nine regional submodels interacting through the trading of goods and services and the mobility of labor and capital. The model integrates intergovernmental fiscal transfers, which play an important role in reducing the disparity in living standards between regions. The analysis demonstrates that the current intergovernmental revenue transfer system has significant inter- and intraregional equity effects, although its nationwide impact is less important. Reducing intergovernmental transfers leads to a reduction in welfare in the four regions where the net transfers were initially positive (Limpopo, Eastern Cape, KwaZulu-Natal, and North West Province). In contrast, welfare increases in the five other regions (Northern Cape, Mpumalanga, Free State, Gauteng, and the Western Cape). When transfer revenues fall and, consequently, regional and local government revenues drop, poor households are the most affected, as they depend more on public services that are essentially financed by governments. When the government's fiscal position improves, it is also poor households that benefit more from additional government expenses.intergovernmental transfer, multiregion applied general equilibrium, consolidation, welfare,

Analysing Alternative Policy Response to High Oil Prices, Using an Energy Integrated CGE Microsimulation Approach for South Africa

An energy-focused integrated CGE microsimulation approach is used to assess the implications of differential government policy responses in South Africa, to increases in international oil prices. The first scenario assumes that increases in world oil and petroleum products are passed through to end users with no changes in government tax/subsidy instruments. The second scenario assumes that the world price increases are nullified by a full price subsidy by government in one scenario, while, in the third scenario, revenues generated from a 50 percent tax on the windfall profit of the synthetic petroleum industry, help to minimize the loss in government revenue. Overall output falls by between 2.2 and 2.5 percent, while the government deficit varies from a worsening of 12 to 22 percent under the three scenarios. Synthetic petroleum, coal, and electricity benefit under the floating price scenario, while none expands its output when a 50 percent tax is levied on the profit of the synthetic petroleum industry. Unemployment increases among medium and low-skilled workers, while skilled workers witness a substantial fall in their remuneration, particularly in rural areas. In both rural and urban areas, women are adversely affected relative to men. The poverty headcount ratio and inequality increase slightly more in the price-setting scenarios relative to the floating-price scenario. Thus, allowing the prices to be passed through to end users probably has a less adverse impact at a macroeconomic level, although there may be adverse distributional consequences.

Computable General Equilibrium Micro-Simulation Analysis of the Impact of Trade Policies on Poverty in Zimbabwe

The paper uses a micro-simulation computable general equilibrium (CGE) model to study the impact on poverty of trade liberalisation in Zimbabwe. The model incorporates 14006 households derived from the 1995 Poverty Assessment Study Survey (PASS). The novelty of this paper is that it is one among a small group of papers that incorporates individual households in the CGE model as opposed to having representative households, allowing for a comprehensive analysis of poverty. The complete removal of tariffs favours export-oriented sectors and all imports increase. Poverty falls in the economy while inequality hardly changes. The results differ between rural and urban areas.Computable General Equilibrium, Trade Liberalisation, Micro-simulation, Poverty, Inequality

The application of economywide techniques as a tool to understand policy impacts

Over the past few decades, the pursuit of sustainable growth and development has been the focus of economic policy in Africa. The challenges confronting Africa range from poverty, unemployment, inequality, insufficient and sometimes, inefficient public service provision, through to environmental degradation. In attempting to solve these problems, African governments have traditionally used a variety of policies: and it is upon the effectiveness and efficiency of such policies that people’s livelihoods depend. However, the practical implementation of a policy may not only fail to achieve the desired outcomes, but may in fact unfairly privilege one group or sphere over another. In this article, it is argued that in order to fully understand the effects of the range of policies available to policy makers, as well as their interconnectivity and cohesiveness, a valuable framework to use is the economy-wide analysis. The article explains such a framework and exposes some applied studies that have employed the framework in order to gain insights into policy analysis. An advantage of the methodology is its quantitative nature which allows for measurement of impacts. It is recommended that such methods ought to be part of a toolkit for policy makers.hb2016School of Public Management and Administration (SPMA
