In this paper, we consider the estimation of a dynamic panel data model with non-stationary multi-factor error structures. We adopted the common correlated effect (CCE) estimation and established the asymptotic properties of the CCE and common correlated effects mean group (CCEMG) estimators, as...

This study delves into the symmetric effects of governance on economic growth for the world’s ten largest economies, employing a model augmented with well-known growth, governance, and control predictors to inform model specification. Using panel and time-series techniques, both collectively...

This study examines the J-Curve phenomenon of a developing country for the case of Ghana and its major trade partners: Switzerland (Swiss) and China. Using quarterly bilateral data from Q1-1995 to Q4-2018 to investigate the impact of currency depreciation on the bilateral trade balance in the...

We study a set of fully modified (FM) estimators in multivariate cointegrating polynomial regressions. Such regressions allow for deterministic trends, stochastic trends, and integer powers of stochastic trends to enter the cointegrating relations. A new feasible generalized least squares...

The environmental Kuznets curve predicts an inverted U-shaped relationship between air pollution and economic growth. Current analyses frequently employ models that restrict nonlinearities in the data to be explained by economic growth only. We propose a Global Trend Augmented Cointegrating...

This study computes Divisia monetary aggregates DM1, DM2, and DM3 for Nige- ria using the Tornqvist-Theil quantity index for the period 2007M12 to 2020M12 and evaluates the performance of the higher-order aggregate (DM3) with a corre- sponding higher aggregate of the simple sum broad money...
