abstract

'Motivated by widely publicized concerns that there are "too many" plans, we structurally estimate (and validate) an equilibrium model of the Medicare Part D market to study the welfare impacts of two feasible, similar-sized approaches for reducing choice. One reduces the maximum number of firm offerings regionally; the other removes plans providing donut hole coverage—consumers' most valued dimension. We find welfare losses are far smaller when coupled with elimination of a dimension of differentiation. We illustrate our findings' relevance under current health care reforms, and consider the merits of instead imposing ex ante competition for entry.'
