We checked against the law of one price between urban and rural consumer price indices of goods and services in Nigeria, using data that span January 1995 to April 2024. By first testing for persistence in price indices, we found a similar pattern of persistence that is non-mean reverting in all...

This policy brief investigates Sierra Leone's interest rate volatility, a recurring concern due to its economic instability. Using the ARDL model and bolstered by the stability exhibited in CUSUM and CUSUM square tests, we explore the impact of deposit and lending interest rates on money demand....

Purpose: The scope of this paper is to see if the aggregate information and communications technology index (ICT) drives firm performance (profitability and efficiency) for BRICS countries from a des-aggregate panel data of the firm-yearly level (by country) during 2014-2022, from an aggregate...

Oil export constitutes the major source of external revenue, and exchange rate determines the naira amount of the revenue and, thus, is perceived to affect aggregate consumption expenditure in Nigeria. This paper employed Nonlinear ARDL approach to examine the short-run and long-run asymmetric...

The study analyses comovement between the real effective exchange rate of South Africa and those of a sample of countries that include the world’s major economies as well as emerging and developing economies. The comovement is examined over the short and long term as well as pre and post the...

The objective of this article is to determine the optimal threshold of public expenditure or optimal size of the State, necessary for economic growth in Cameroon over the period 1982 to 2023. The hypotheses on the conditionality of the optimal allocation of said expenditure at a threshold, and...

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...

The purpose of this paper is to analyze the dynamics of crude oil prices of OPEC and non-OPEC countries using threshold cointegration. To capture the long-run asymmetric price transmission mechanism, we develop an error correction model within a threshold cointegration and CGARCH errors...

This paper analyses the impact and correlation of different education indicators on the economic growth of Kosova from 2012 to 2022. Using time-series data, this paper applies the Cobb-Douglas production function as a measurement model. The main findings demonstrate a mixed impact on growth,...
