According to Philip Parker, the relationship between physics-based physiology and macroeconomics may come to dominate explanations of economic growth.
His argument focuses on the so-called equatorial paradox -the phenomenon that a country's latitude explains up to 70% of cross-country variances in per capita income.
After introducing concepts from physics and physiology as the building blocks of homeostatic utility, he explains the role of homeostatic utility in economic growth.
Specifically, he shows that a country's performance is gauged not by its absolute level of income or consumption, but by how far it is from a homeostatic steady state governed by what he calls physioeconomics.
Countries closer to their homeostatic steady state grow more slowly than those farther away.
