This paper tests the prediction of the Permanent Income Hypothesis (PIH) that news about future income induce a revision in consumption equal to the revision in permanent income. We use time-series data from 48 contiguous US states to perform the test. The empirical results provide some support...

A transactions model of the demand for multiple media of exchange is developed. Some results are expected, and others are both new and surprising. There are both extensive and intensive margins to currency substitution, and inflation may affect the two margins differently, leading to subtle...
