South Africa´s trade barriers are still relatively high compared to other emerging market economies, and its industrial policy still preferentially treats certain industries. Based on a static GTAP model, we estimate the economic impact of further trade liberalization on the South African...

This paper provides an overview of the structure, key functions, and characteristics of the motorcycle parts and aftermarket industries in Southern Africa in order to identify challenges to and opportunities for growth in these industries. The research examines the end markets and utilization of...

This working paper is the fourth in a series that forms part of the project 'Southern Africa - Towards Inclusive Economic Development', a three-year partnership between UNU-WIDER and the South African government aimed at generating a better understanding of regional value chains and supporting...

Recent empirical work finds a negative correlation between product market regulation and aggregate employment. We examine the effect of product market regulations on hours worked in a benchmark aggregate model of time allocation as well as in a standard dynamic model of entry and exit. We find...

The informal sector (IS) plays a significant role in developing countries viz. the provision of employment, income and supplying ignored markets. However, working and employment conditions within the sector are still poor. Its expansion and changing structures have thus drawn the attention of...

In many countries hospital regulation undergoes fundamental change. In reaction to steadily increasing costs, authorities switch from cost of service regulation to prospective payment systems (PPS). While it seems clear that this new scheme sets strong cost saving incentives, this is not so...

We analyze a dynamic multi-pollutant problem where abatement costs of several pollutants are not separable. The pollutants can be either technological substitutes or complements. Environmental damage is induced by the stock of accumulated pollution. We find that optimal emission paths are...

We study long-term incentives for polluting and regulated firms to invest in advanced abatement technologies, when some new technology is available but an even better technology will be expected in the future. Firms can invest only once. We find that depending on the adoption fixed costs all...

We analyze a dynamic multi-pollutant problem where abatement costs of several pollutants are not separable. The pollutants can be either technological substitutes or complements. Environmental damage is induced by the stock of accumulated pollution. We find that optimal emission paths are...

Starting from the premise that firms are distinct in terms of their capacity to create radical product innovations, the present paper attempts to explore how firms choose between different forms of R&D cooperation and their consequences for social welfare. It studies a duopolistic market, where...
