With rising access to electronic health record data, application of artificial intelligence to create clinical risk prediction models has grown. A key component in designing these models is feature generation. Methods used to generate features…

A growing body of research in economics focuses on whether cultural differences in social norms affect economic outcomes. Here we examine how differences in the strength of social norms — or tightness-looseness (TL) — across countries can explain…

We study a Bayesian k-armed bandit problem in many-armed regime, when k ≥ √ T, with T the time horizon. We first show that subsampling is critical for designing optimal policies. Specifically, the standard UCB…

We propose and describe a corporate carbon reporting framework intended to strengthen the credibility and transparency of the existing net-zero pledges. We refer to this framework as the Time-Consistent Corporate Carbon Reporting (TCCR…

Objective: To characterize price trends and variation for US generic and branded drugs at the retail level as they relate to pharmacy acquisition costs and local market factors.

Since humanity’s first steps, individuals have used nonverbal cues to communicate and infer leadership, such as walking ahead of others. Menon et al., (2010) showed that the use of spatial ordering as cue to leadership differs across cultures:…

Randomized clinical trials (RCT) are the gold standard for informing treatment decisions. Observational studies are often plagued by selection bias, and expert-selected covariates may insufficiently adjust for confounding. We explore how…

Women continue to be underrepresented in leadership positions. This underrepresentation is at least partly driven by gender stereotypes that associate men, but not women, with achievement-oriented, agentic traits (e.g., assertive and decisive).…

U.S. Veterans Affairs (VA) patients’ multi-system use can create challenges for VA clinicians who are responsible for coordinating Veterans’ use of non-VA care, including VA-purchased care (“Community Care”) and Medicare. To examine the…

This article studies the impact of business modernization on the sales performance of traditional retailers in an emerging market. The authors define modernization as the adoption of physical structures and tangible practices of organized retail…

We conducted a longitudinal study, using logistic regression to examine how outpatient care fragmentation in FY14 (as measured by number of unique providers, Breslau’s Usual Provider of Care (UPC), Bice-Boxerman’s Continuity of Care Index (COCI…

Can differences in beliefs about politics, particularly the benefits of war and peace, move markets? During the Siege of Paris by the Prussian army (1870–71) and its aftermath, we document that the price of the French 3% sovereign bond (rente)…

Quantification has been constitutive of psychology since its inception and is core to its scientific status. The adoption of qualitative methods eschewing inferential statistics is therefore unlikely to obtain. Rather than discarding useful tools…

Encouraging vaccination is a pressing policy problem. To assess whether text-based reminders can encourage pharmacy vaccination and what kinds of messages work best, we conducted a megastudy. We randomly assigned 689,693 Walmart pharmacy patients…

We propose a definition for the average indirect effect of a binary treatment in the potential outcomes model for causal inference under cross-unit interference. Our definition is analogous to the standard definition of the average direct effect…

DAOs can reshape society by bringing democratic control to important economic and social activities previously governed through more hierarchical means. But as many people have pointed out, DAOs have not yet achieved their goal of true…

We model a market for a skill in short supply and high demand, where the presence of charlatans (professionals who sell a service they do not deliver on) is an equilibrium outcome. In the model, reducing the number of charlatans through…

U.S. state legislatures are critical policymaking bodies and the major pipeline of candidates to national office. Polarization in state legislatures has increased substantially in recent decades, yet we understand little about the role of…

In response to the complexity, challenges, and slow pace of innovation, health care organizations are adopting interdisciplinary team approaches. Systems engineering, which is oriented to creating new, scalable processes that perform with higher…

We investigate the relationship between private firms’ disclosures and the demand for the equity of their publicly traded peers. Using data on the global…
