Ever since the dawn of merchanting, traders have sought ways to ease the cost of transactions. The recent growth of information and communication technology provided a wide range of solutions for international and national transactions by introducing ecommerce. As a result of this development, e-commerce recently emerged as a dominant transaction activity with a significant impact on the national economies. In recent years the potential of e-commerce has been widely discussed, with a particular focus on its effects on greater economic welfare and prosperity. Yet, despite an abundance of studies that have been done on investigating the role of e-commerce in an economy, a thorough and detailed econometric examination on its impact is still an underexplored avenue. This paper attempts to bridge this gap by investigating the impact of volume of online transactions (e-commerce) and gross capital formation on economic growth, using panel data on 31 European countries covering a 16 years’ period. The empirical panel data model is estimated by employing the Generalized Method of Moments. The main findings from the study show that e-commerce and gross capital formation have positive and significant effects on GDP per capita based on purchasing power parity, with e-commerce having a weaker development-enhancing effect in comparison to gross capital formation. In addition, this paper proposes a fruitful discussion on how to provide balance between the growth of e-commerce, the focus on improving other aspects and generating optimal economic welfare and prosperity. Our paper ends with directions for future research.
