Homo Oeconomicus or Homo Reciprocans?

The last Nobel Prize in economics was awarded to Richard Thaler for his contributions to Behavioral Economics. Behavioral Economics challenges the standard, neoclassical assumption that economic decision makers are fully rational and only concerned about their own material well-being. Over the last decades new models of human behavior have been developed, often inspired and tested by fascinating economic experiments. In this lecture I will focus on "social preferences", a subfield of behavioral economics to which Thaler and many other economists and psychologists contributed. It seems obvious that many people are not only motivated by their own material well-being but often care about other people. Altruism, spite, inequality aversion, concerns for fairness and reciprocal behavior have an important impact on economic decision making. However, it is often difficult to disentangle the exact motivations that are driving economic behavior. In this lecture I will give a brief introduction into this field and discuss some recent experiments on the dark side of social preferences. [mehr]

New approaches to stable models for computational plasma physics

Due to the presence of multiple physical scales and complex nonlinear interactions, the numerical simulation of fusion plasmas often leads to computational problems of huge complexity. A long-standing challenge is then to design numerical methods that are computationally efficient, high order accurate and stable on very long time scales. Fortunately, steady progresses in the theory of structure-preserving discretizations have provided a solid mathematical ground for the development of stable high order numerical schemes. In this lecture I will give a brief review of the compatible Finite Element methods that have been developed in this direction, and I will explain how these tools are now being extended to design stable numerical models for the Vlasov-Maxwell equations. Recent ideas that allow to further improve the computational efficiency of such methods will be presented, along with a novel approach to low-noise particle approximations. [mehr]
