In the Grossman model, individuals do not demand healthcare directly — they demand health, and healthcare is one input to producing it. What is the practical implication of this distinction?
AHealthcare spending should be minimized because it is not valued in itself
BPolicies should evaluate healthcare interventions based on how effectively they produce health (outcomes), not on the volume of care delivered (inputs)
CHealthcare and health are identical concepts
DIndividuals always prefer more healthcare regardless of its health impact
The derived demand framework means healthcare is a means, not an end. A surgical procedure, drug, or hospital stay has value only insofar as it improves health. This implies that more healthcare is not always better — a procedure that does not improve outcomes is waste. It provides the theoretical basis for outcomes-based evaluation, value-based care, and the entire field of health technology assessment.
Question 2 Short Answer
The Grossman model predicts that more educated individuals are more efficient producers of health. What mechanism could explain this, and what is the observable implication?
Think about your answer, then reveal below.
Model answer: More educated individuals may be better at processing health information, choosing effective treatments, adhering to medications, maintaining healthy behaviors, and navigating the healthcare system. The implication is that education affects health above and beyond its effect through income — educated people get more health per dollar spent on healthcare inputs. Observationally, education predicts health outcomes even after controlling for income, which is consistent with the Grossman model's production efficiency hypothesis.
The efficiency hypothesis is distinct from the allocative hypothesis (education changes how resources are allocated among health inputs) and the time-preference hypothesis (education correlates with patience, which affects health investment decisions). Distinguishing these mechanisms has important policy implications: if education directly improves health production efficiency, investing in education is a health intervention.
Question 3 True / False
In the Grossman model, the rate of health depreciation increases with age. This directly explains why healthcare expenditure rises with age.
TTrue
FFalse
Answer: True
As the depreciation rate rises with age, maintaining the health stock at any given level requires increasing investment — more healthcare, more frequent medical visits, more medication. At some point, the cost of maintaining the optimal health stock exceeds the benefit, and the individual allows health to decline. Eventually, health falls below the minimum required for survival. This framework predicts the sharply rising healthcare expenditure profile observed in every population: older individuals must invest more just to slow the decline, even if they cannot fully offset depreciation.
