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…

Individuals often engage in brokering behaviors intended to influence other people’s interactions and relationships. An open research question in the nascent literature on brokering as a social process concerns its situational antecedents. We…

Accounting studies often examine whether the relation between X and Y varies with a moderating variable, M, by including an interactive term, X × M, in a regression. We provide plain-English guidance…

The relative scarcity of policy-relevant research is the inevitable result of editorial policies pursued by most if not all of the highest status management and organization science journals. Ironically, there are a plethora of policy-oriented…

We use administrative data from the U.S. Census Bureau to estimate the causal effects of loose credit conditions on firm employment and worker earnings. To obtain quasi-random variation in firms’ exposure to credit booms, we exploit the…

We examine a dynamic disclosure model in which the value of a firm follows a random walk. Every period, with some probability, the manager learns the firm’s value and decides whether to disclose it. The manager maximizes the market perception of…

Problem Definition: The paper focuses on an innovative bank-intermediated trade finance contract, which we call dynamic trade finance DTF, under which banks dynamically adjust loan interest rates as an order passes…

Previous research focused on popular U.S. Supreme Court rulings expanding rights; however, less is known about rulings running against prevailing public opinion and restricting rights. We examine the impact of the Dobbs v. Jackson Women’s…

There are a number of available methods for selecting whom to prioritize for treatment, including ones based on treatment effect estimation, risk scoring, and handcrafted rules. We propose rank-weighted average treatment effect (RATE) metrics as…
