In doing so, it uses Tobit and censored quantile regressions to analyse household survey data in 1993-94 and 2004-05. We find upward sloping Engel curves which implies that there is a consistent increase in the household budget share allocated to services in the aggregate and to each individual services category as total household expenditure increases. This is a powerful explanation for the increasing share of the services sector
