Abstract: Advance market commitments (AMCs) have been proposed as mechanisms to stimulate investment by suppliers of products to low-income countries, where familiar mechanisms such as patents and prizes can fall short. In an AMC, donors commit to a fund from which a specified subsidy is paid per unit purchased by low-income countries until the fund is exhausted, strengthening suppliers’ incentives to invest in research, development, and capacity. A $1.5 billion pilot AMC was undertaken to speed the roll out of a pneumococcus vaccine to the developing world covering additional strains prevalent there.

This paper undertakes the first formal analysis of AMCs. We construct a model in which an altruistic donor bargains with a supplier on behalf of a low-income country over vaccine price and quantity ex post, after the supplier has sunk ex ante investments. We use this model to explain the broad logic of an AMC—as a solution to a hold-up problem—as well as to analyze specific features of the pilot’s design that we argue enhance its efficiency. We study a variety of design features including capacity forcing, supply commitments, price ceilings, and accrued interest, and consider a variety of economic environments including competing suppliers, competing demand from middle-income countries outside the program. We show that optimal AMC design differs markedly depending on where the product is in its development cycle.
