This article investigates the relationship among foreign direct investment,\ntrade openness and economic growth in Ghana taking the period of\npost-liberalization covering 1975-2017. The Augmented Dickey-Fuller (ADF)\ntest for unit root, regression analysis, descriptive analysis, and Pearson correlation\nwas used to investigate the relationships. ADF test for unit root result\nshows all variables to be integrated of order one, that is they are stationary\nafter the first difference. The study extracted and used secondary data sources\nderived from the World Development Indicators (WDI) of the World Bank\nand Bank of Ghana website over the period 1975-2017. The study proxied\nforeign direct investment, inflation, and trade openness were used as an independent\nindicator while GDP growth (annual %) was the dependent indicator.\nUsing the Ordinary Least Squares (OLS) estimator, the study revealed\nthat trade openness is the main factor affecting GDP growth (annual %) in\nGhana. Also, the study finds that foreign direct investment and Inflation had\n(-, or +) impact but were not statistically significant on GDP growth (annual\n%). Therefore, the study concludes by recommending robust measures\nto enhance trade openness in terms of encouraging exports and inflow of FDI\nthrough the creation of an enabling and friendly environment to do business\nfor output growth dynamics in Ghana.
