In this paper we analyse household income mobility dynamics among Africans in South Africa?s most populous province, Kwazulu-Natal, between 1993 and 1998. Compared to industrialized and most developing countries, mobility has been quite high, as might have been expected after the transition in...

The effects of competition on growth are analyzed in the recent literature by comparing economies with the same market structure but different degrees of substitutability. In this note, we show that in a general equilibrium model with monopolistic competition – la Dixit- Stiglitz the effect of...

This paper extends Hall's (1988) methodology to analyse imperfections in both the product and the labour market for firms in the Belgian manufacturing industry over the period 1988- 1995. We investigate the heterogeneity in price-cost mark-up and workers' bargaining power parameters among 18...

This paper examines an economy with a large number of industries, each producing a different good. Technological change follows a Poisson process where firms improve their productivity through investment in R&D. The less there are firms in the economy or the more they can coordinate their...

This paper examines an economic union where oligopolistic firms produce by skilled and unskilled labor and do in-house R&D by skilled labor. The planner of the union accepts new members to the union, regulates the labor market through a minimum wage for unskilled labor and supports firms by...

High unemployment in many OECD countries is often attributed, at least in part, to the generosity and long duration of unemployment compensation. It is therefore instructive to examine a country where high unemployment exists despite the near complete absence of an unemployment insurance system....

This paper uses efficiency wage theory and the existence of community-based sharing to hypothesize that labor markets in developing countries have multiple equilibria - the same economy can be stuck at different levels of unemployment with different levels of wages. The model is meant for...

The financial and economic crisis of 2008 and 2009 has taken its toll on the South African economy. The economy contracted for the first time since 1998, and entered recession during the fourth quarter of 2008. The GDP contraction was soon transmitted to the labor market. Between the second...

We estimate the wage penalty associated with working in the South African informal sector. To this end we use a rich data set on non-self employed males that allows one to accurately distinguish workers employed in the informal sector from those employed in the formal sector and link individuals...
