“…More so, most of the conventional multi-variate co-integrational tests which are most appropriate for large samples, the ARDL bounds test is suitable for a small sample size. Finally, according to Pesaran, Shin, and Smith (2001) ARDL generally provides unbiased estimates of the long run model and valid t-statistic even when some of the regressors are endogenous.Other studies that have also adopted this model include; Anthony-Orji, Orji, Ogbuabor, and Nwosu (2019), Anthony-Orjis, Orji, Ogbuabor, and Nwosu (2018) and Orji, Ogbuabor, and Anthony-Orji (2016). Equation 1 can be modified into an economic model as shown below: ) Econometrically, Equation 2 could be modified as thus; ) However, Equation 3 can further be modified into the general form of Auto-Regressive Distributed Lag model, i.e.…”
