September 2008The Welfare Impact of Reducing Choice in Medicare Part D: A Comparison of Two Regulation Strategies
with Claudio Lucarelli, Kosali Simon: w14296
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, as in the latter approach. We illustrate our findings’ relevance under current health care reforms, and consider the merits of instead imposing ex ante competition for entry.

May 2006The Diffusion of the Internet and the Geography of the Digital Divide in the United States
with Shane Greenstein: w12182
This paper analyses the rapid diffusion of the Internet across the United States over the past decade for both households and firms. We put the Internet's diffusion into the context of economic diffusion theory where we consider costs and benefits on the demand and supply side. We also discuss several pictures of the Internet's physical presence using some of the current main techniques for Internet measurement. We highlight different economic perspectives and explanations for the digital divide, that is, unequal availability and use of the Internet.
