Portfolio Balance Approach To Asymmetries, Structural Breaks And Financial Crisis: Testing A Model For Nigeria, Portfolio Balance Theory, Oluwasegun B. Adekoya
CBN Journal of Applied Statistics (JAS)
This study tests the Portfolio Balance Theory (PBT) for Nigeria for the period starting from September 1997 to September 2018. It extends the hypothesized linear inverse relationship between exchange rate and stock price to include asymmetries and structural breaks. It further examines the impact of the 2008 global financial crisis on the PBT to determine its stability after the crisis. The full sample results show that the PBT holds for Nigeria and asymmetries and structural breaks matter in the nexus between stock price and exchange rate. However, the impact of stock price on exchange rate diminished in the long-run with …

This paper examined the long memory features of GDP per capita data before the global financial crisis, using a sample of 26 African countries. The study employed fractional integration and tested the stability of the differencing parameter across the sample period for each country. The results indicated that most of the countries’ GDP series were I(1) or higher. Evidence of mean reversion was observed in 10 countries where the disturbances were autocorrelated. There was strong evidence against mean reversion in the remaining 16 countries. The results also indicated that the fractional differencing parameter was stable in 17 countries, while the …
