Conspicuous consumption, conspicuous health, and optimal taxation

We present a simple model of status-seeking over multiple socioeconomic domains by introducing the concept of conspicuous health as an argument in the utility function, in addition to the well-established conspicuous consumption term. We explore the implications of such a utility function for optimal non-linear taxation, where an increase in concerns for conspicuous health has an opposite effect on the marginal tax rate, compared to an increase in concerns for conspicuous consumption. Using life satisfaction panel data from Australia, along with an improved measure of exogenous reference groups (that accounts for the 'time era' of respondents), we find empirical evidence of a comparison health effect.
