Trade Technology and Employment: A case Study of South Africa

This paper provides a comprehensive analysis of the impact of trade on employment in South Africa. Firstly, it considers the correlation between trade liberalisation and factor demand in South African manufacturing during the 1990s. Secondly, it investigates the impact of trade on labour using a Chenery (1979) style decomposition technique, following Edwards (2001a, 2001b, 2005b) and Jenkins (2002). It develops the earlier work by exploring both the indirect and the indirect effects and investigating variations in the regional impact of trade on factor demand during the 1990s. This suggests that technological change accounts for the bulk of jobs lost in manufacturing during the 1990s. To investigate, whether this reflects exogenous technological change or trade-induced technological change requires undertaking an econometric analysis and this explores the impact of trade on technological change through an induced labour demand model. This finds a strong effect of exogenous technological progress but only limited evidence that increased trade flows and trade liberalisation induced improvements in labour productivity.Trade; technology; employment; industrial panel

Rip/singularity free cosmology models with bulk viscosity

In this paper we present two concrete models of non-perfect fluid with bulk viscosity to interpret the observed cosmic accelerating expansion phenomena, avoiding the introduction of exotic dark energy. The first model we inspect has a viscosity of the form ${\zeta} = {\zeta}_0 + ({\zeta}_1-{\zeta}_2q)H$ by taking into account of the decelerating parameter q, and the other model is of the form ${\zeta} = {\zeta}_0 + {\zeta}_1H + {\zeta}_2H^2$. We give out the exact solutions of such models and further constrain them with the latest Union2 data as well as the currently observed Hubble-parameter dataset (OHD), then we discuss the fate of universe evolution in these models, which confronts neither future singularity nor little/pseudo rip. From the resulting curves by best fittings we find a much more flexible evolution processing due to the presence of viscosity while being consistent with the observational data in the region of data fitting. With the bulk viscosity considered, a more realistic universe scenario is characterized comparable with the {\Lambda}CDM model but without introducing the mysterious dark energy.Comment: 9 pages, 6 figures, submitted to EPJ-
