Impact of Space on Food Sales: An experiment in a Brazilian supermarket

Abstract

This article evaluate the space-sales elasticity of a basket of food products. The research adopted a before-after experiment with a control group. We change product spaces in a supermarket for these five categories and then analyze what happened with sales. Results show that all types of food varied above the control group. However, only the three categories considered essential and present in consumption habits had statistical confirmation based on the Chi-Square Test.
