We find that a changing influence of an individual's role models due to her increasing income, which entails new reference groups providing social identity, leads to the diffusion of new consumption behaviors. Thereby, the resulting Engel curves' shape depends on the underlying learning dynamics. ...

can destabilize one of the core zeitgebers we rely on in making critical decisions regarding attainable goals. This relationship between speed of inner time on thex-axis and synchronization between inner and outer time on they-axis forms another inverted U-shape curve in the nested hierarchy [...
This paper shows that the quadratic shape of the Engel curve for alcohol is induced by preference heterogeneity between drinkers and abstainers in a Japanese data set. With controlling the heterogeneity, it is shown that the Engel curve for alcohol slopes monotonically downwards for drinkers, and ...
