    Are there bubbles in the housing market of Namibia?: An analysis of historical evidence
    (University of Namibia, 2017) Nyambe, Crever; Vijayakumar, Kandaswamy R.; Gnitchogna, Rodrique
    The dividend yield ratio in the stock markets is, to an extent, comparable to the rent price ratio in the housing market. Taking advantage of this definitional similarity, one can then use the traditional unit root test for log dividend yield in this case, the log rent-price ratio to test for the existence of real estate bubbles. Such unit root tests are conducted for the whole of Namibia. We develop a continuous and monthly rent price information-based method to track the periods when real estate prices diverge from their fundamental levels. The effect of those investigations would suggest the existence of pockets of bubbles in the real estate market. We finally get to distinguish of the pockets of bubbles observed, which minor, intermediate and major bubbles are.

    Stochastic behavior of South African rand exchange rate
    (University of Namibia, 2017) Shigwedha, Jacob N.; Vijayakumar, Kandaswamy R.; Gnitchogna, Rodrique
    The study of fluctuations of exchange rates is one of many active research areas in the international finance. This paper is concerned with modeling of exchange rates of the South African Rand, through which the Namibian Dollar accesses the international market. It uses some standard models and tools of quantitative analysis, such as Random walk, Martingale hypothesis, Auto Regressive model (AR), Auto regressive polynomial model (PN), Feed forward artificial neural network (NN), functional coefficient model and non-parametric regression model (NP), to closely look at stochastic behaviors of the South African Rand exchange rates against thirteen currencies of countries that are major trade partners to and within Southern African nations. Due to increasing international trade volumes, Southern African nations are more and more exposed to the international community, and trading in both goods and services that are affected to a large extent by movements in exchange rates.
