Experienced Utility, Engel Curves and Expenditure Choices

This study examines how individual spending behaviours change for different levels of experienced utility using a composite SWB indicator as a utility proxy and modelling expenditure behaviours through Engel curves across different utility regions. To perform the analysis, we use expenditure and SWB data for Italian residents in 2016 and estimate Engel curves through a non-parametric instrumental variable threshold regression approach. Our findings indicate that individual spending behaviours are characterized by distinct experienced utility functions, with respect to different goods' categories and durability, and corroborate the strict association between conspicuous consumption, social aspects of life, and well-being.
