Cross-national research on cultural differences across space and time intersects multiple disciplines but the prominence of concepts varies by academic fields. Hofstede's dimensional concept of culture, to begin with, dominates in cross-cultural psychology and international management. Inglehart's dynamic concept of culture, by contrast, prevails in sociology and political science. We argue that this disciplinary division is unfortunate because the two concepts are complementary, for which reason a synthesis rectifies their mutual weaknesses. Indeed, while Hofstede's dimensional concept neglects cultural dynamics, Inglehart's dynamic concept is dimensionally reductionist. We demonstrate empirically that combining these two concepts leads to an improved understanding of cultural differences. Inspired by Hofstede's cultural dimensions, we use data from the European Value Studies and World Values Surveys for 495,011 individuals born between 1900 and 1999 in 110 countries and then show that change on these dimensions proceeds as Inglehart and his collaborators suggest. Most notably, younger generations have become more individualistic and more joyous. But even though economic development and generational replacement drive this cultural change, roughly half of the variation in national cultural orientations is unique to each country, due to lasting intercept differences in developmental trajectories that trace back to remote historic drivers. We discuss the implications for cross-national cultural research.
