The 1/d Law of Giving

چکیده
We combine survey data on friendship networks and individual characteristics with experimental observations from dictator games. Dictator offers are primarily explained by social distance giving follows a simple inverse distance law. While student demographics play a minor role in explaining offer amounts, individual heterogeneity is important for network formation. In particular, we detect significant homophilous behavior students connect to others similar to them. Moreover, the network data reveal a strong preference for cliques students connect to those already close. The study is one of the first to identify network architecture with individual behavior in a strategic context.

متن کاملExistence of Conservation Laws in Nilpotent Case
Using the Spencer-Goldschmidt version of the Cartan-Kähler theorem, we prove the local existence of conservation laws for analytical quasi-linear systems of two independent variables in the nilpotent and 2-cyclic case. Introduction A conservation law for a (1-1) tensor field h on a manifold M , dimM = n, is a 1-form θ which satisfies dθ = 0 and dh∗θ = 0, where h∗ is the transpose of h : h∗θ := ...

The domain of attraction of a 1-stable law on R d is characterised by the expansions of the characteristic functions of its elements. k=1 X k , are given by the well known stable laws.
