Abstract

The Exact Affine Stone Index (EASI) demand model offers distinct advantages over its predecessors. However, it does not account for pre-committed demand. This can bias elasticity estimates when such pre-commitments are present. We derive a generalized EASI model that allows for pre-committed demand. We illustrate the advantage of this model in an empirical analysis of food demand in Russia using provincial-level panel data. The results provide strong empirical evidence for the presence of pre-committed demand for key food commodities. The findings extend the literature on food demand in Russia by estimating elasticities that account for pre-commitments and unobserved regional heterogeneity.
