SEMI-ENDOGENOUS VERSUS SCHUMPETERIAN GROWTH MODELS: TESTING THE KNOWLEDGE PRODUCTION FUNCTION USING INTERNATIONAL DATA

Using various indicators of innovative activity and product variety in the OECD countries over the past century, this paper tests whether first- and second-generation models of economic growth are consistent with the data over time and across countries. The estimation results give evidence in favour of Schumpeterian models while the semi-endogenous growth theories are not consistent with the data.Schumpeterian growth theory, semi-endogenous growth theory

Discovering cultural differences (and similarities) in facial expressions of emotion

Understanding the cultural commonalities and specificities of facial expressions of emotion remains a central goal of Psychology. However, recent progress has been stayed by dichotomous debates (e.g., nature versus nurture) that have created silos of empirical and theoretical knowledge. Now, an emerging interdisciplinary scientific culture is broadening the focus of research to provide a more unified and refined account of facial expressions within and across cultures. Specifically, data-driven approaches allow a wider, more objective exploration of face movement patterns that provide detailed information ontologies of their cultural commonalities and specificities. Similarly, a wider exploration of the social messages perceived from face movements diversifies knowledge of their functional roles (e.g., the ‘fear’ face used as a threat display). Together, these new approaches promise to diversify, deepen, and refine knowledge of facial expressions, and deliver the next major milestones for a functional theory of human social communication that is transferable to social robotics
