In this paper we are primarily concerned with assessing the degree of capital mobility in sub-Saharan Africa. Using the methodology as proposed by Feldstein and Horioka (1980)-later termed the "Feldstein-Horioka puzzle"-we test the hypothesis of perfect capital mobility against the alternative...

In order to address practical questions in credit portfolio management it is necessary to link the cyclical or systematic components of firm credit risk with the firm’s own idiosyncratic credit risk as well as the systematic credit risk component of every other exposure in the portfolio. This...

Active credit portfolio management is becoming a central part of capital and credit management within the banking industry. Stimulated by the Basel II capital accord the estimation of risk sensitive credit and capital management is central to success in an increasingly competitive environment....

The causal link between tourism receipts and GDP has recently become a major focus in the tourism economics literature. Results obtained in recent studies about the causal link appear to be sensitive with respect to the countries analysed, sample period and methodology employed. Considering the...

This paper analyses the intertemporal hedging demand for stocks and bonds in South Africa, the United Kingdom and the United States. The analysis is done using an approximate solution method for the optimal consumption and wealth portfolio problem of an infinitely long-lived investor. Investors...

This paper contributes to the growing literature on the milex-growth nexus, by providing a case study of South Africa and considering the possibility of structural breaks by applying newly developed econometric methods. Using full sample bootstrap Granger non-causality tests, no Granger causal...

This paper attempts to provide evidence indicating that the purchasing power parity (PPP) puzzle is becoming less of a puzzle. It present the results of Augmented Dickey-Fuller test, non-linear tests of non-stationarity and Bayesian unit root tests, applied to 10 Southern African Development...

This paper utilises "a class test for fractional integration" associated with the seminal contribution of Hinich and Chong to appraise the possibility that Southern African Development Community (SADC) real exchange rates can be treated as long memory processes. The justification for considering...

This study investigates the asymmetric and time-varying causality between inflation and inflation uncertainty in South Africa within a conditional Gaussian Markov switching vector autoregressive (MS-VAR) model framework. The MS-VAR model is capable of determining both the sign and direction of...

One characteristic of many macroeconomic and financial time series is their asymmetric behaviour during different phases of a business cycle. Oil price shocks have been amongst those economic variables that have been identified in theoretical and empirical literature to predict the phases of...
