easi: EASI Demand System Estimation
"easi" is a package for R enabling the estimation of the
Exact Affine Stone Index demand system of Pendakur and Lewbel
(2009). However, more than just a transcript, it offers a
number of extensions in an unified framework. Firstly, it
allows to calculate elasticities (income elasticities, price
elasticities and demographic elasticities) and their standard
deviations. Secondly, it enables the calculation and the
graphical representation of Engel curves and their confidence
interval. Thirdly, it provides simulation tools to assess the
impact of price changes, income changes and demographic changes
on fitted budget shares, elasticities, and their standard
deviations. Finally, easi allows the computation of equivalent
incomes.
