title: Modelling asymmetric and nonlinear features in the natural resource wealth-economic complexity nexus: empirical insights from Nigeria
abstract: Abstract Contrary to previous research, this study makes a unique contribution to the global discussion by incorporating asymmetric structure and nonlinearity into the analysis of how changes in natural resource wealth affect economic complexity. To achieve this objective, the study uses a nonlinear autoregressive distributed lag (ARDL) and a fully modified ordinary least squares estimator, utilizing data from Nigeria spanning the period 1984–2021. Unlike earlier studies, this study establishes
