The United Nations Sustainable Development Goals (UNSDGs) elaborately promote “sustained, inclusive, and sustainable economic growth, full and productive employment, and decent work for all” (Goal 8: SDGs). Considering that there has not been any cross-country comparison of the role of intellectual capital in career success, this study examines the nexus between intellectual capital and career success through the channels of income inequality, information, and communication technology from 1997 to 2018 for six European Economic Area (EEA) countries with high human development index (HDI). Using the Pooled Mean Group Autoregressive distributive lag model, results show that there is a positive and linear relationship between intellectual capital, income inequality, information and communication technology, and career success in the long run. Findings from the causality test reveal there is one-way causality running from information and communication technology and career success as well as intellectual capital to career success. These findings suggest that intellectual capital is important for career success; therefore, policymakers need to invest in developing and improving intellectual capital to ensure objective career success among the nationals.
