Changes in child monetary poverty under the different scenarios simulated in this analysis are captured through a Cobb-Douglas approach, using household specific preferences but with fixed budget shares. A more sophisticated approach allowing for substitution effects, such as an Almost Ideal Demand System (AIDS), was not possible with the available micro data.7 Aggregate household consumption, deflated by a per adult equivalent scale based on minimum caloric needs and by relevant spatial and temporal deflators, is the variable used to assess changes in monetary poverty, according to country specific absolute poverty lines. Changes in real expenditure are affected by two main channels: income and consumer prices.
