    Abstract: We present complete results pertaining to the dynamical stability for sender-receiver games following Lewis (1969), and Nowak and Krakauer (1999) under the selection-mutation dynamics. Our research reveals that two distinct classes of neutrally stable strategies have a distinguishing feature of the dynamic stability. The rest points close to the strategies of these classes are asymptotically stable and all rest points other than these are not.Length: 47 pages

  2. By: Anke Becker; Benjamin Enke; Armin Falk
    Abstract: Variation in economic preferences is systematically related to both individual and aggregate economic outcomes, yet little is known about the origins of the worldwide preference variation. This paper uses globally representative data on risk aversion, time preference, altruism, positive reciprocity, negative reciprocity, and trust to uncover that contemporary preference heterogeneity has its roots in the structure of the temporally distant migration patterns of our very early ancestors: In dyadic regressions, differences in preferences between populations are significantly increasing in the length of time elapsed since the ancestors of the respective groups broke apart from each other. To document this pattern, we link genetic and linguistic distance measures to population-level preference differences (i) in a wide range of cross-country regressions, (ii) in within-country analyses across groups of migrants, and (iii) in analyses that leverage variation across linguistic groups. While temporal distance drives differences in all preferences, the patterns are strongest for risk aversion and prosocial traits.

  3. By: Gori, Luca; Sodini, Mauro
    Abstract: The aim of this research is to build on a theory for explaining economic development in a (neoclassical) growth model with endogenous fertility. The economy is comprised of overlapping generations of rational and identical individuals and identical competitive firms producing with a constant-returns-to-scale technology with no externalities. From a theoretical perspective, the distinguishing feature of this work is that endogenous fertility per se is able to explain the existence of low and high development regimes. It provides alternative reasons (history driven or expectations driven) why some countries enter development trajectories with high GDP and low fertility and others experience under-performances with low GDP and high fertility. The model is also able to reproduce fertility fluctuations and explain the baby busts and baby booms observed in the last century in some developed countries.

    Abstract: How persistent is public goods provision in a comparative perspective? We explore the link between infrastructure investments made during antiquity and the presence of infrastructure today, as well as the link between early infrastructure and economic activity both in the past and in the present, across the entire area under dominion of the Roman Empire at the zenith of its geographical extension (117 CE). We find a remarkable pattern of persistence showing that greater Roman road density goes along with (a) greater modern road density, (b) greater settlement for-mation in 500 CE, and (c) greater economic activity in 2010. Interestingly, however, the degree of persistence in road density and the link between early road density and contemporary economic development is weakened to the point of insignificance in areas where the use of wheeled vehicles was abandoned from the first millennium CE until the late modern period. Taken at face value, our results suggest that infrastructure may be one important channel through which persistence in comparative development comes about.
