We provide a nonparametric revealed preference approach to demand analysis based on homothetic efficiency. Homotheticity is a useful restriction but data rarely satisfies testable conditions. To overcome this we provide a way to estimate homothetic efficiency of consumption choices. It...

This article provides a robust non-parametric approach to demand analysis based on a concept called homothetic efficiency. Homotheticity is a useful restriction or assumption but data rarely satisfy testable conditions. To overcome this problem, this article provides a way to estimate homothetic...

This paper assumes that migrants derive utility from their own consumption, their own leisure, and remittances to their family. It hypothesizes that the labor supply and remittances of Mexican migrants in the U.S. are jointly determined. Shits in real exchange rates affect the cost of sending a...

The evaluation of bank efficiency is the premise and guidance of high-quality development of the banking industry. On the basis of the existing research on bank efficiency, the operation process of banks is divided into two stages of saving collection and making profits. Based on the conditions...

This paper reviews the theory of the true cost of living index and its approximation through superlative index numbers, as well as the Vartia quantum theory of bias in index numbers as applied to substitution bias in consumer price indices. Estimated adjustments are proposed for the Argentine...
