First what issues have we addressed? • Typical issue differ depending on the type of data: time series versus cross section.
TS issues: • period of observation, • functional form, • dynamics, • endogeneity, • separability, • testing/imposing restrictions, • demographic and other effects, and • changes in tastes & preferences.
CS issues: • demographic effects, • adult equivalence scales, • endogeneity, • zero consumption and the reasons for them, • household production, • unit values and • quality.
