- Description: What I will present here is based on my grappling over the past three decades with one of the central problems of social science – the relationship between social structure and human agency. This is not a new problem for social scientists; from Karl Marx, who understood that human beings make history, but not in circumstances of their choosing; to the French structuralists who conceived the term ‘relative autonomy’ and ‘overdetermination’; to Anthony Giddens’ ‘structuration theory’ and other contemporary sociologists. What is new are the changing physical circumstances of the world in which we live, which mean that human society can no longer afford to analyse ourselves and our social, political and economic systems independently of the natural world.

- Description: Exchange rates are one of the most essential determinants of a country's economic performance in terms of level of trade. Since the exchange rate is one of the best indicators of competitiveness, this study sought to examine the behaviour of the rand against other emerging countries in the South African exchange market. The study explored the trends and estimated the forecasting accuracy of six currency markets using ARCH-family and Random walk models over the period 1994 to 2013.The six currency markets examined were the Rand/Dollar, Rand/Pound, Rand/Euro, Rand/Yen and Rand/Pula. The Rand exchange rates did exhibit the characteristics of volatility clustering and asymmetric effects suggesting volatility of the Rand. Exchange rates tend to rise when there is more bad news in the financial market than good news and positive shocks imply a higher next period conditional variance than negative shocks of the same sign.
