Stone-Geary preferences and competitive equilibrium
This is a paper using a competitive monopolistic framework (in GE). It is an old paper by Stratz (1989). Recent work with Stone-Geary preferences relates to the issue of structural transformation following the work of Herrendorf, Rogerson and Valentinyi (2013), although there is considerable debate on whether these preferences appropriately capture the data. All these papers have a representative consumer, with expenditure shares changing over time due to growth.
