The Brazilian population is experiencing transitions resulting from changes in the levels of mortality and fertility. One implication of this process is the increase in life expectancy, a fact which directly reflects the individual's consumption pattern. In this context, this paper aims to analyze the impact of changes in household preferences toward health goods and services, on macroeconomic indicators and welfare, according to a General Equilibrium approach. The main finding shows that changes in preferences and prices toward health goods imply a rise in income to compensate the consumer for price changes.
