Abstract Recent developments in identifying economic and social phenomena within the theory and laws of physics do not provide a sufficient basis of information for economists. In this article, an interdisciplinary analysis in microeconomics, is proposed to overcome this limit by establishing a new economic theory in the way of better analyzing economic problems from the methodological perspectives of physics. This new theoretical approach is tested on a model using individual time use values that identifies how life satisfaction may be defined through economic utility so as to better investigate the income-happiness paradox as pointed out by Easterlin. The theoretical analysis point out that an increase in happiness would depend on the ability to replace subsidiaries with conspicuous consumption so long as they have common characteristics that satisfy the same needs. This consumption pattern implies that consumers would draw more satisfaction from less usage of conspicuous goods than from higher usage of subsidiaries, under given budget and time constraints.
