|July 2016||The Empirical Economics of Online Attention|
with Andre Boik, Shane Greenstein: w22427
In several markets, firms compete not for consumer expenditure but instead for consumer attention. We model and characterize how households allocate their scarce attention in arguably the largest market for attention: the Internet. Our characterization of household attention allocation operates along three dimensions: how much attention is allocated, where that attention is allocated, and how that attention is allocated. Using click-stream data for thousands of U.S. households, we assess if and how attention allocation on each dimension changed between 2008 and 2013, a time of large increases in online offerings. We identify vast and expected changes in where households allocate their attention (away from chat and news towards video and social media), and yet we simultaneously identify rem...
|July 2015||Information Technology and Patient Health: Analyzing Outcomes, Populations, and Mechanisms|
with Seth Freedman, Haizhen Lin: w21389
We study the effect of hospital adoption of electronic medical records (EMRs) on health outcomes, particularly patient safety indicators (PSIs). We find evidence of a positive impact of EMRs on PSIs via decision support rather than care coordination. Consistent with this mechanism, we find an EMR with decision support is more effective at reducing PSIs for less complicated cases, using several different metrics for complication. These findings indicate the negligible impacts for EMRs found by previous studies focusing on the Medicare population and/or mortality do not apply in all settings.
|September 2008||The 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 2006||The 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.
