Shareholders want a firm's objective function to place some weight on consumer welfare, motivated by both self-interested and altruistic motivations. Firms have a unique technology for improving consumer welfare: lowering inefficient price markups, which increases consumer welfare more than it lowers profits. Optimal pricing formulas can be adapted to account for shareholders' marginal rate of substitution between profits and consumer welfare. Calibrations from preference parameters show many shareholders should place non-trivial weights on consumer welfare. A survey experiment on a representative sample elicits how shareholders would vote on resolutions giving strategic guidance to firms on what objective to pursue. Only 7% would vote for pure profit maximization. The median individual is indifferent between $0.44 in profits or $1 in consumer surplus, with those owning stocks preferring a lower weight on consumer welfare than non-stockholders.
