We conducted two experiments on PayPal’s Give at Checkout feature to learn about the effect of 1) information about charity outcomes on donations, and 2) exposure to these point-of-sale microgiving requests on subsequent giving. In this “…

We study specialized lending in a credit market competition model with private information. Two banks, equipped with similar data processing systems, possess “general” signals regarding the borrower’s quality. However, the specialized bank gains…

We document regime change in the U.S. Treasury market post-Global Financial Crisis (GFC): dealers switched from a net short to a net long position in the Treasury market. We first derive bounds on Treasury yields that account for dealer balance…

Many proposed surface water transfers undergo a series of regulatory reviews designed to mitigate hydrological and economic externalities. While these reviews help limit externalities, they impose substantial transaction costs that also limit…

Cities worldwide struggle with overloaded transportation systems and their externalities. The emerging autonomous transportation technology has the potential to alleviate these issues, but the decisions of profit-maximizing operators running…

To advance tailored recruitment, management, and on-the-job socialization, we present a complementary “job fit” framework that integrates intrinsic, extrinsic, relational, and prosocial job design attributes. Employing polynomial regression…

In this paper, we study the design and analysis of experiments conducted on a set of units over multiple time periods where the starting time of the treatment may vary by unit. The design problem involves selecting an initial treatment time for…

We study the dynamics between local segregation, partisanship, and political polarization. We exploit large-scale, exogenous and high-stakes peer assignment due to universal conscription of soldiers assigned from each of 34,947 municipalities to…

We present the results of a large field experiment on setting reserve prices in auctions for online advertisements, guided by the theory of optimal auction design suitably adapted to the sponsored search setting. Consistent with the theory,…

We study an economy with traders whose payoffs are quasilinear and whose private signals are informative about an unobserved state parameter. The limit economy has infinitely many traders partitioned into a finite set of symmetry classes called…

From job candidates to entrepreneurs, people often face an inherent tension between the need to share personal accomplishments and the need to avoid appearing arrogant. We propose that humorbragging — incorporating self-enhancing humor into self-…

Retirement policy is often predicated on the belief that more saving is always better, at least at the margin. This belief is used to justify the increasingly widespread practice of automatically enrolling workers in employer-sponsored defined…

Importance Optimizing insulin therapy for patients with type 2 diabetes can be challenging given the need for frequent dose adjustments. Most patients receive suboptimal doses and do not achieve glycemic control.

…

We use the lens of weak signal asymptotics to study a class of sequentially randomized experiments, including those that arise in solving multiarmed bandit problems. In an experiment with n time steps, we let the mean reward gaps between…

Consumer technology products are changing lifestyle behaviors like how we eat, how we sleep, and how we get around, but existing research has not examined whether they are being designed to promote healthy choices. This study assesses the health…

We characterize the relation between exchange rates and their macroeconomic fundamentals without committing to a specific model of preferences, endowment or menu of traded assets. When investors can trade home and foreign currency risk-free bonds…

Widespread adoption of hydrogen as an energy carrier is widely believed to require continued advances in Power-to-Gas (PtG) technologies. Here we provide a comprehensive assessment of the dynamics of system prices and conversion efficiency for…

We study the investment incentives created by truthful mechanisms that allocate resources using approximation algorithms. Some approximation algorithms guarantee nearly 100% of the optimal welfare in the allocation problem but guarantee nothing…

We analyze a large-scale randomized field experiment in which a search engine varied the prominence of search ads for 3.3 million U.S. users: one group of users saw the status quo, while the other saw a lower level of advertising (with search ads…
