We construct an event-based outcome measure of firm-level environmental, social, and governance (ESG) impact for public and private firms globally from 2007 to 2015 using data from RepRisk. Then, we measure the societal impact of corporate social responsibility (CSR) engagements using...

One of the major differences between markets that follow a “sharing economy” paradigm and traditional two-sided markets is that the supply side in the sharing economy often includes individual nonprofessional decision makers, in addition to firms and professional agents. Using a data set of...

Using a multi-tier mapping of supply chain relationships constructed from granular global, firm-to-firm supplier--customer linkages data, we quantify the degree of financial risk propagation from the supply network beyond firms' direct supply chain connections and isolate structural network...

We develop a technique that incorporates the instrumental variable method into a causal tree to correct for potential endogeneity biases in heterogeneous treatment effect analysis using observational studies. The resulting instrumental variable tree approach partitions subjects into subgroups...

Market thickness is a key parameter that can make or break a platform's business model. Thicker markets can offer more opportunities for participants to meet and higher chances that a potential match exists. However, they can also be vulnerable to potential search frictions. In this paper, using...

This study addresses three important questions concerning personalized health care: (1) Are outcome differences between hospitals heterogeneous across patients? (2) If they are, how valuable is patient-centric information (that accounts for heterogeneity) to patients in selecting a hospital? and...

Problem Definition: We address two key questions faced by patients, physicians and policy makers: (1) how do different types of patients benefit differently from elite surgeons, and (2) how can outcome data be used to achieve better health care at both the individual and social levels?...

BACKGROUND The 2014 American Heart Association/American College of Cardiology Valvular Heart Disease Guidelines state that mitral valve diseases should be repaired at a Center of Excellence (CoE). We evaluate the cost-effectiveness of such referrals. METHODS We estimate patients’ life...
