This article contains a review of the seminal Grossman model from a perspective of assumptions and simplifications, which were necessary to make the model tractable. The Grossman model emphasises health as a fundamental commodity, which implies that the demand for healthcare is a derived demand; in the model, individuals are both consumers and producers of health. The model predicts that an individual would invest in health until the marginal benefit of health equals its marginal cost; this equilibrium demand for health entails that the length of an individual's life would be determined endogenously. This review also discusses the model's refinements and extensions that have relaxed some of the constraints of the original model. In spite of its shortcomings, the Grossman model remains — even after 40 years — one of the few models in the realm of health economics, which attempts to conceptualise the complex demand for health and healthcare both theoretically and empirically. Članek pregledno predstavlja privzetke in poenostavitve Grossmanovega modela, ki so potrebni, da bi bil model rešljiv. Grossmanov model opredeljuje zdravje kot temeljno dobrino, kar pomeni, da je povpraševanje po zdravstveni oskrbi izpeljano povpraševanje; v modelu so posamezniki tako »potrošniki« kot »proizvajalci zdravja«. Model napoveduje, da bo posameznik tako dolgo vlagal v svoje zdravje, dokler marginalna korist zdravja ne bo enaka marginalnim stroškom zdravja; to ravnovesno povpraševanje po zdravju tako endogeno določa trajanje posameznikovega življenja. Ta pregled obravnava tudi dopolnitve in razširitve modela, ki sproščajo nekatere omejitve prvotnega modela. Kljub pomanjkljivostim je Grossmanov model — celo po 40 letih — eden redkih modelov na področju ekonomije zdravja, ki tako teoretično kot tudi empirično poskuša konceptualizirati kompleksno zahtevo po zdravju in zdravstvenem varstvu.
