This paper develops the structure and closure of an econometric regime-switching model within a partial equilibrium framework that has the ability to generate reliable estimates and projections of endogenous variables under market switching regimes. Models used in policy evaluation usually...

There is growing evidence that freshwater availability is declining, while competition among sectors for the withdrawal of this scarce resource is rapidly increasing,(Rosegrant et a, 2002). Therefore, the need to promote inter-sectoral water use efficiency from the demand-side management has...

Abstract This paper investigates the competitiveness of small and medium-scale maize milling enterprises in South Africa from estimates of a translog stochastic cost frontier model. Results suggest that small and medium-scale maize mills in South Africa are cost-inefficient, operating at 59...

This study develops a multi-equation partial equilibrium model of the Malawi maize market which is linked sequentially to a local maize economy to show that the skepticism surrounding the use of innovation systems in agricultural research in Africa is not unfounded. The results demonstrate that...

The difference between hypothetical and real values when evaluating consumers’ preferences (termed ‘hypothetical bias’) has received significant attention in scientific literature, as the outcome of this bias is often an overestimation of willingness to pay (WTP) values. This is the main...

Commercial producers, brokers, exporters and spinners dominate the wool supply chain in South Africa. Until recently smallholder farmers in the Transkei region had limited access to a profitable market outlet for their wool. In response, the South African wool industry has taken the initiative...

With the emergence of private food safety and quality standards in developed countries fruit exporting countries in the developing world face increasing constraints to access markets in the rich industrialised countries in the North. Producers in the South have no alternative as to make the...

While water supply sources are dwindling in South Africa, the demand for the scarce water resource is increasing. This situation requires a switch from supply to demand management of water in the country. The study updates the 1999 social accounting matrix for South Africa, using the Trade and...

Most of the climate change models for South Africa predict a reduction in freshwater availability by 2050, which implies that water availability for sectoral production activities is expected to decline. This decline has an impact on sectoral output, value added and households’ welfare. Using...
