    Abstract: According to the widely known ‘culture of honor’ hypothesis from social psychology, traditional herding practices have generated a value system conducive to revenge-taking and violence. We test the economic significance of this idea at a global scale using a combination of ethnographic and folklore data, global information on conflicts, and multinational surveys. We find that the descendants of herders have significantly more frequent and severe conflict today, and report being more willing to take revenge in global surveys. We conclude that herding practices generated a functional psychology that plays a role in shaping conflict across the globe.

    Abstract: In this survey, we argue that the economic analysis of fertility has entered a new era. First-generation models of fertility choice were designed to account for two empirical regularities that, in the past, held both across countries and across families in a given country: a negative relationship between income and fertility, and another negative re- lationship between women’s labor force participation and fertility. The economics of fertility has entered a new era because these stylized facts no longer universally hold. In high-income countries, the income-fertility relationship has flattened and in some cases reversed, and the cross-country relationship between women’s labor force participation and fertility is now positive. We summarize these new facts and describe new models that are designed to address them. The common theme of these new theories is that they view factors that determine the compatibility of women’s career and family goals as key drivers of fertility. We highlight four factors that facilitate combining a career with a family: family policy, cooperative fathers, favorable social norms, and flexible labor markets. We also review other recent developments in the literature, and we point out promising new directions for future research on the economics of fertility.

    Abstract: Eigen mode selection ought to be a practical issue in some real game systems, as it is a practical issue in the dynamics behaviour of a building, bridge, or molecular, because of the mathematical similarity in theory. However, its reality and accuracy have not been known in real games. We design a 5-strategy game which, in the replicator dynamics theory, is predicted to exist two eigen modes. Further, in behaviour game theory, the game is predicted that the mode selection should depends on the game parameter. We conduct human subject game experiments by controlling the parameter. The data confirm that, the predictions on the mode existence as well as the mode selection are significantly supported. This finding suggests that, like the equilibrium selection concept in classical game theory, eigen mode selection is an issue in game dynamics theory.

    Abstract: Forced displacement as a consequence of wars, civil conflicts, or natural disasters does not only have contemporaneous consequences but also long-run repercussions. This eclectic overview summarizes some recent research on forced displacement in economic history. While many of the episodes covered refer to Europe, this survey points to literature across all continents. It highlights new developments, and points to gaps in the literature.
    Keywords: forced displacement, wars, disasters, networks
