The Role of Decision Support Systems in Attenuating Racial Biases in Healthcare Delivery

Authors: Kartik K. Ganju, Hilal Atasoy, Brad Greenwood and Jeff McCullough

Publication: Management Science, Volume 66, Issue 11, November 2020, Pages 5171-5181.

Abstract:

Although significant research has examined how technology can intensify racial and other outgroup biases, limited work has investigated the role information systems can play in abating them. Racial biases are particularly worrisome in healthcare, where underrepresented minorities suffer disparities in access to care, quality of care, and clinical outcomes. In this paper, we examine the role clinical decision support systems (CDSS) play in attenuating systematic biases among black patients, relative to white patients, in rates of amputation and revascularization stemming from diabetes mellitus. Using a panel of inpatient data and a difference-in-difference approach, results suggest that CDSS adoption significantly shrinks disparities in amputation rates across white and black patients—with no evidence that this change is simply delaying eventual amputations. Results suggest that this effect is driven by changes in treatment care protocols that match patients to appropriate specialists, rather than altering within physician decision making. These findings highlight the role information systems and digitized patient care can play in promoting unbiased decision making by structuring and standardizing care procedures.

Cross-Listings and the Dynamics between Credit and Equity Returns

Authors: Patrick Augustin, Feng Jiao, Sergei Sarkissian, Michael J Schill

Publication: The Review of Financial Studies, Vol. 33, Issue 1, January 2020

Abstract:

We study how listing in multiple markets affects the dynamics between firms’ credit default swap (CDS) and stock returns. We find that cross-listing increases (1) the sensitivity of CDS to stock returns, (2) the integration of CDS with world equity and bond markets, and (3) the statistical synchronicity of CDS and stock prices. Our results are stronger for firms with greater media attention, analyst and CDS coverage, and Google search intensity and for listings in familiar markets. We suggest that a firm’s presence in global equity markets comes with an improvement in the credit-equity integration through a reduction of informational frictions.
