Descripción
This paper proposes a finite mixture model (FMM) to model the behavioral transition
of calorie consumption with an assumption that nutrition consumption is a mixture of
two different behavioral stages: a poor stage and an affluent stage. Based on 387
calorie-income elasticities collected from 90 primary studies, our results identify that
the threshold income for calorie demand transition is 459.8 USD in 2012 prices (PPP).
It implies that the transitional threshold for calorie consumption is 1.26 dollar/day,
which is slightly lower than the World Bank poverty line (1.25 dollar/day in 2005
PPP prices).
