In medicine, clinicians treat individuals under an implicit assumption that high-risk patients would benefit most from the treatment (‘high-risk approach’). However, treating individuals with the highest estimated benefit using a novel machine-…

Using detailed search data from half a million anonymous job seekers, we study the information content of earnings announcements for job seekers. In the spirit of Beaver (1968), we find evidence that job seekers initiate job-search activity in…

We consider off-policy evaluation of dynamic treatment rules under sequential ignorability, given an assumption that the underlying system can be modeled as a partially observed Markov decision process (POMDP). We propose an estimator, partial…

We examine the spillover effect of public firm disclosures on the patent trading market. The patent market is rife with information frictions, yet can potentially facilitate the reallocation of innovation to the most productive users. We find…

Using comprehensive data on U.S. corporate bond trades since 2002, we find evidence that retail bond investors over rely on untimely credit ratings to their financial detriment. Specifically, they appear to select bonds by first screening on a…

We develop a framework to measure the value of free goods and services available on the internet. The conventional method of measuring consumer surplus based on monetary expenditures is ineffective because these goods’ prices are predominantly…

We study how personalized news aggregation for rationally inattentive voters (NARI) affects policy polarization. In a two-candidate electoral competition model, an attention-maximizing infomediary aggregates source data about candidates’ valence…

Through their products and services, businesses have a meaningful impact on their customers’ health. When markets reward products that induce unhealthy behaviors, like poor diet and limited physical activity, they fuel the chronic disease…

Discourse about people seeking refuge from conflict varies considerably. To understand what components of this discourse reach refugees the most, we examined refugees’ perceptions of how their host communities perceive them (i.e., intergroup…

Importance: A wide variety of novel medical diagnostics and devices are determined safe and effective by the US Food and Drug Administration (FDA) each year, but to our knowledge the literature lacks evidence documenting how long it takes to…

We study the impact of government-led incentive systems by examining a staggered reform in the Chinese state-owned enterprise (SOE) performance evaluation policy. To improve capital allocative efficiency, starting in 2010, regulators evaluating…

Grabbing and keeping your audience’s focus is critical to communication success. What you have to say is important, so give yourself the best chance to convey your message to your audience by first gaining attention, but then, more importantly,…

To reduce spending and improve quality, some primary care clinics in the USA have focused on high-need, high-cost (HNHC) Medicare beneficiaries, which include clinically distinct subpopulations: older adults with frailty, adults under 65 years…

A new National Academies of Sciences, Engineering, and Medicine report, “Achieving Whole Health: A New Approach for Veterans and the Nation,” redefines what it means to be healthy and creates a roadmap for health systems, including the Veterans…

Numerous multinational firms have recently pledged to reduce their greenhouse gas emissions to a net-zero position by the year 2050. These pledges currently lack a unified measurement and reporting structure, leaving the public unsure about the…

Search engines and e-commerce platforms have substantial difficulty exposing new products to their users on account of an information problem: new products typically do not have enough sales or other user engagement that enables platforms to…
