This paper presents a detailed empirical examination of the South African equity premium, and a quantitative theoretic exercise to test the canonical inter‐temporal consumption‐based asset‐pricing model under power utility. Over the long run, the South African stock market produced average returns six to eight percentage points above bonds and cash, and at the 20‐year horizon, an investor would not have experienced a single negative realised equity premium over the entire 105‐year period we examine. Yet the maximum equity premium rationalised by the consumption‐based model is 0.4%. The canonical macro‐financial model closely matches the average risk‐free rate, using realistic parameters for the coefficient of risk aversion and a positive rate of time preference.
