— Let R be a 2-dimensional normal excellent henselian local domain in which 2 is invertible and let L and k be its fraction field and residue field respectively. Let ΩR be the set of rank 1 discrete valuations of L corresponding to codimension 1 points of regular proper models of Spec R. We prove that a quadratic form q over L satisfies the local-global principle with respect to ΩR in the follo...

This paper combines ISSP survey data and experimental evidence from a giftexchange game to determine the effect of status or relative income on work effort. We find a strong effect of others’ incomes on individual effort decisions in both datasets. The individual’s rank in the income distribution has a more powerful effect on effort than does others’ average income, suggesting that comparisons ...
