Significant departures from log normality are observed in income data, in violation of Gibrat’s law. We identify a new empirical regularity, which is that the distribution of consumption expenditures across households is, within cohorts, closer to log normal than the distribution of income. We...

Both direct utility function and Frisch cost function representations of demand system rank are derived. The results are used to construct a revealed preference (GARP) type test of rank. They are also used to derive results involving block separability, additive separability, and the class of...

The Hicks-Leontief composite commodity theorem permits aggregation of sets of goods that have identical price movements into composite groups of goods, each of which can be treated like a single good for demand analysis. Here Hicks-Leontief is generalized by permitting composite commodities to...
