Conspiracies are consequential and social, yet online conspiracy groups that consist of individuals (and bots) seeking to explain events or a system have been neglected in sociology. We extract conspiracy talk about the COVID-19 pandemic on…

Multi-sector efforts to address the structural drivers of health inequities faced by racial and ethnic minority communities in the USA often ignore the potential of action by for-profit businesses, perhaps due to skepticism about the role of…

Decisions take time, and the time taken to reach a decision is likely to be informative about the cost of more precise judgments. We formalize this insight using a dynamic model of optimal evidence accumulation. We provide conditions under which…

Early in the COVID-19 pandemic, US Veterans Health Administration (VHA) employee occupational health (EOH) providers were tasked with assuming a central role in coordinating employee COVID-19 screening and clearance for duty,…

Negative healthcare delivery experiences can cause lasting patient distress and medical service misuse and disuse. Yet no multi-site study has examined whether care-team members understand what most upsets patients about their care.

Congress has been grappling with an ambitious agenda this legislative session, debating plans to support working families with child care, tax credits, housing support, preschool education, and other efforts to strengthen the middle class.1 In…

Labor economists regularly analyze employment data by fitting predictive models to small, carefully constructed longitudinal survey datasets. Although modern machine learning methods offer promise for such problems, these survey datasets are too…

Two intermediary-based factors — a corporate bond dealer inventory measure and a broad intermediary distress measure — explain more than 40% of the puzzling common variation in credit spread changes beyond canonical structural factors. A…

Under what conditions can members of poor disenfranchised communities survive and even foster entrepreneurship in environments where violence is cheap? How do such conditions alter ethnic identities and political institutions? In this paper, we…

Modern digital advertising platforms allow ads to be targeted in a variety of ways, and generally aim to match the ad being shown with either the user or the content being shown. In this study, we examine the effect of matching in emotional…

Background: Health care delivery system features can have a profound effect on how frontline physicians and other clinical personnel in primary care practices (primary care providers [PCPs]) view the quality and safety of what…

Importance Home dialysis rates for end-stage kidney disease (ESKD) treatment are substantially lower in the US than in other high-income countries, yet there is limited knowledge on how to increase these rates.

Free association among words is a fundamental and ubiquitous memory task. Although distributed semantics (DS) models can predict the association between pairs of words, and semantic network (SN) models can describe transition probabilities in…

In honor cultures, relatively minor disputes can escalate, making numerous forms of aggression widespread. We find evidence that honor cultures’ focus on virility impedes a key conflict de-escalation strategy — apology — that can be successfully…

How does a failure in a retailer’s mobile app impact shoppers’ purchases in its online (website and app) and offline (brick-and-mortar store) channels? Our main hypothesis is that an app failure has a negative effect on offline purchases and no…

For individuals who take on the responsibility of caring for another person due to illness, disability, or declining abilities, it can often be challenging, lonely, costly, and exhausting. As the U.S. continues to address the impact of the…

This report describes insights gleaned from the Data Fellows collaboration among PayPal, Northwestern University’s Kellogg School of Management, the Golub Capital Social Impact Lab at Stanford University’s Graduate School of Business, and…

We revisit the classic result on the (non-)existence of pure-strategy Nash equilibria in the Generalized First-Price Auction for sponsored search advertising and show that the conclusion may be reversed when ads are ranked based on the product of…

A wide variety of cultural practices have a ‘tacit’ dimension, whose principles are neither obvious to an observer, nor known explicitly by experts. This poses a problem for cultural evolution: if beginners cannot spot the principles to imitate,…
