In order to explain the substantial recent increases in obesity rates in the United States, we consider the effect of falling food prices in the context of a model involving endogenous body weight norms and an explicit, empirically grounded description of human metabolism. Unlike previous...

A reputational model of debt is examined from an evolutionary game perspective. The game is played between randomly matched opponents and we ask whether debt can be supported in the long run steady state when lenders are given the option of joining an information sharing coalition. The players...
