This paper uses four ADF-type unit root tests and four KPSS-type stationarity tests to examine whether the gender unemployment gap would converge to zero in Africa. Among these different tests, the two most restricted models, namely the ADF test and the KPSS test, indicate no convergence in the...

This paper deals with the analysis of inflation in financial returns by using model-free connectedness framework which includes investigating persistence in the series and data from 22 countries from April 1958 to November 2023 which are grouped into highly, medium and lowly correlated returns....

We investigate the possibility of convergence and catching up of life expectancy values of West African countries with those of North African countries. Following the theory of time series convergence documented in Bernard and Durlauf (1996) and Greasley and Oxley (1997), we apply more robust...

This present paper investigates the mean reversion in household consumption expenditure in 38 Africa countries, the expenditure series obtained as the percentage of nominal Gross Domestic Product (GDP), each spanning 1990 to 2018. Due to the small sample point of available time series of...

We investigate long-range dependence and linear trend in the famosity of popular Nigerian music artists such as Davido, Burna Boy, Tiwa Savage, and Wizkid by relying on their Web, News, Image and YouTube Google Trends searches. The available weekly datasets span 13.09.2015 to 06.09.2020....

This paper investigates BRIC markets’ integration and segmentation between REITs and stock indices, and the possibility of establishing “wealth” and “credit” effects. The analysis of the relationship is based on updated techniques in time series using the concepts of fractional...

As a result of the adverse macroeconomic effect of inflation on welfare, fiscal budgeting, trade performance, international competitiveness and the whole economy, inflation still remains a subject of utmost concern and interest to policy makers. The traditional Philips curve as well as other...

The BRICS market represents high growth economies. This paper empirically examines the long-run equilibrium as well as the short-run linkages between the BRICS REIT markets and the REIT markets in developed countries (United States, Australia and the United Kingdom). We employ fractional...

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...

This paper studies the impact of inflation and exchange rate on conditional stock market volatility. Sentana’s QGARCH model is generalized to include the asymmetries in inflation and exchange rate that are not allowed in linear GARCH (p, q) model of Bollerslev (1986). Nonlinear specifications...
