- Description: Real exchange rate volatility have important effects on production, employment and trade, so it is crucial to understand its impact on unemployment especially on a country like South Africa.This study analyses the impact of the real exchange rate volatility on unemployment and the dynamic adjustment of unemployment rate following shocks to its determinants using quarterly South African data covering the period 2000 to 2010. It begins with a review of literature on the impact of exchange rate volatility on unemployment and provides a brief updated background on the exchange rate and unemployment in South Africa. An empirical model linking the real exchange rate to unemployment is then specified. In contrast to previous analyses, this study augments the cointegration and vector autoregression (VAR) and the GARCH model including analysis with impulse response and variance decomposition analyses to provide robust long run effects and short run dynamic effects on the unemployment rate. The empirical analysis using a variety of specifications,estimation techniques, and robustness tests suggests that exchange rate volatility has a statistically and economically significant impact on employment. The variables that have been found to have a long run relationship with unemployment rate include the real exchange rate, exports ,real interest rate and the gross domestic product.The impulse response functions broadly corroborate the theoretical predictions, but only real interest rate and exports have a significant impact on unemployment in the short run. Results from the variance decompositions are largely similar to those from the impulse response analysis. The real exchange rate and exports are the only variables found to significantly explain the variation in the unemployment. The most interesting result that emerged from this analysis and is supported by previous research is that among other determinants, the real exchange rate explain the largest proportion of the variation in unemployment rate. On balance, the evidence therefore suggests that unemployment rate fluctuations are predominantly equilibrium responses to real exchange rate shocks in comparison with interest rates, economic growth and exports. , Thesis (MCom) -- Faculty of Management and Commerce, 2013

- Description: This study analyses the determinants of demand for public transport in South Africa, using quarterly data covering the period from 1990-2009. The study initially provides an overview of the South African public transport system and population trends. Based on the review of the theoretical and empirical literature on transport, the study specifies a model of public transport demand in South Africa. Tests for stationarity and unit roots in the series (both informal and formal tests), and co-integration test have been performed. The co-integration test is done using the Johansen (1990, 1995) methodology. A vector error correction model is run to provide robust determinant variables on public transport. The results revealed that in the short run, the demand for public transport depends positively and significantly on GDP per capita growth and negatively on prices for public transport and fuel prices. However, over the long run, the demand for public transport depends negatively on GDP per capita growth as expected, but positively on the other variables including the growth in employment levels. To check for robustness of the VECM results the diagnostic tests were performed. The AR Roots Graph reports the inverse roots of the characteristics AR polynomial. The graph showed that all roots lie inside the unit circle which is an indication that VAR is stable. Some of the results found in this the study, such as the short run and long run impact of income growth on public demand, are supported by findings from other studies. , Thesis (MCom) -- Faculty of Management and Commerce, 2011
