Overuse of medical care is often attributed to an informed expert problem, whereby doctors induce patients to purchase unnecessary treatments. Alternatively, patients may drive overuse of medications by exerting pressure on doctors to overprescribe, undermining the doctor's gatekeeping function...

Pre-Analysis Plans (PAPs) for randomized evaluations are becoming increasingly common in Economics, but their definition remains unclear and their practical applications therefore vary widely. Based on our collective experiences as researchers and editors, we articulate a set of principles for...

Multiple price lists are a convenient tool to elicit willingness to pay (WTP) in surveys and experiments, but choice patterns such as "multiple switching" and "never switching" indicate high error rates. Existing measurement approaches often do not provide accurate standard errors and cannot...

Can information about the value of diagnostic tests improve provider practice and help patients recognize higher quality of care? In a randomized experiment at public clinics in Mali, health providers and patients received tailored information about the importance of rapid diagnostic tests...

We study the pattern of correlations across a large number of behavioral regularities, with the goal of creating an empirical basis for more comprehensive theories of decision-making. We elicit 21 behaviors using an incentivized survey on a representative sample (n=1,000) of the U.S. population....

An enormous literature documents that willingness to pay (WTP) is less than willingness to accept (WTA) a monetary amount for an object, a phenomenon called the endowment effect. Using data from an incentivized survey of a representative sample of 3,000 U.S. adults, we add one (probably)...

We provide a full behavioral characterization of the standard Shannon model of rational inattention. The key axiom is "Invariance under Compression", which identifies this model as capturing an ideal form of attention-constrained choice. We introduce tractable generalizations that allow for many...

We develop a revealed preference test for optimal acquisition of costly information. The test encompasses models of rational inattention, sequential signal processing, and search. We provide limits on the extent to which attention costs can be recovered from choice data. We experimentally elicit...

The model of rational inattention with Shannon mutual information costs is increasingly ubiquitous. We introduce a new solution method that lays bare the general behavioral properties of this model and liberates development of alternative models. We experimentally test a key behavioral property...

We use four incentivized representative surveys to study the endowment effect for lotteries in 4,000 U.S. adults. We replicate the standard finding of an endowment effect--the divergence between Willingness to Accept (WTA) and Willingness to Pay (WTP), but document three new findings. First, we...
