PurposeThis paper investigates the relationship between human capital, economic freedom, governance performance, and economic growth and whether institutional factors such as governance performance and economic freedom mediate the association between human capital and economic growth.Design/methodology/approachIn this study, the authors apply the panel data regression method to verify five hypotheses and check the robustness of the empirical findings from four aspects (chow test, panel unit root test, granger test and generalized method of moments) based on the data covering China, India, Russia, Brazil and South Africa from 2000 to 2018.FindingsAfter multiple tests with mixed methods, the empirical results show that the relationship between human capital and economic growth is not linear but inverted U-shaped. Furthermore, human capital has a positive effect on economic growth only in a certain period of time, and governance performance positively moderates the effect of human capital on economic growth in BRICS.Originality/valueFirst, the impact of human capital on economic growth is not linear but an inverted U-shaped and governance performance moderates the effect of human capital on economic growth in BRICS. The study and research model enhances the authors’ insights on the advantage and challenges of human capital in the future. Second, the proposed multi-methods in the study accurately forecast economic growth which partially solves endogenous problems because of reverse causality.

Public service motivation contains distinctive cultural characteristics. Different cultural backgrounds shape public service motives with different connotations and levels. However, the traditional cultural values rooted in historical development and socialization process have not received enough attention in the research on public service motivation. In order to investigate the influence of Confucian culture based on Chinese scenes on public service motivation, in the current study we collected 1308 representative questionnaires from 12 cities in central and eastern China, and adopted the dual fixed effect model and moderating effect model to verify six hypotheses. The empirical results showed that Confucian culture has different effects on public service motivation from four dimensions, namely, attraction to politics and policy making (APP), commitment to public interest (CPI), compassion (COM), and self-sacrifice (SS). The paternalistic leadership plays a part in moderating the influence of Confucian culture on public service motivation. This study not only expands the cross-cultural applicability of the theory of public service motivation in non-western countries, but also supplements the evidence of research on public service motivation in East Asian countries. In practice, it is necessary for the organizations to consider the importance of specific cultural values for organizational culture and personal value orientation.
