The purpose of this study is to examine the time-frequency relationship in the Fisher's effect for South African Customs Union (SACU) countries using continuous wavelet transforms. We use the Wavelet power spectrum to decompose the nominal interest rate and inflation rate across a time frequency...

The purpose of our study is to examine the Fishery-based Environmental Kuznets Curve (EKC) for a sample of 48 African countries between 1970-2019. We estimate cubic EKC-type models using quantile regression to account for distributional asymmetries existing in the time series data, and our...
