The term “diversity,” although widely used, can mean different things. Diversity can refer to heterogeneity, i.e., the distribution of people across groups, or to the representation of specific minority groups. We use a conjoint experiment with a…

The article offers information about the platform annexation, and the logic using basic principles from platform economics. It analyzes the platform annexation to the traditional antitrust categories in the market. It mentions that a platform…

Adaptive experiments present a unique opportunity to more rapidly learn which of many treatments work best, evaluate multiple hypotheses, and optimize for several objectives. For example, they can be used to pilot a large number of potential…

Recent scandals over the manipulation of LIBOR, foreign exchange benchmarks, and other financial benchmarks have spurred policy discussions over their appropriate design. We characterize the optimal fixing of a benchmark as an estimator of a…

THE DIPLOMA FOR the Sveriges Riksbank Prize in Economics Sciences in Memory of Alfred Nobel that I shared in 2020 with Paul Milgrom cites “improvements in auction theory and inventions of new auction formats.” As requested by the Royal Swedish…

As supply chains become more and more globalized, even in times of disruptions and trade frictions, and as consumers are increasingly more demanding on the environmental and social responsibility performances of the supply chains that supply…

In recent decades, global flows of assets and goods have grown rapidly relative to GDP and have shifted aggressively during crises such as the global financial crisis and the current pandemic. Corporations and governments increasingly borrow from…

Optimally reallocating human capital to tasks is key for an organization to successfully navigate a transition. We study how to design employment contracts to allocate employees to different valuable projects within an organization given two…

Comprehensive global decarbonization requires that transportation services cease to rely on fossil fuels for power generation. This paper develops a generic, time-driven life-cycle cost model for mobility services to address two closely related…

Using MBA textbook finance, we look at three simple examples to illustrate why the r-g measure of the fiscal cost of deficits is incomplete. We start by considering the case of risky government debt. Second, we consider the case of risk-free debt…

Computationally efficient contextual bandits are often based on estimating a predictive model of rewards given contexts and arms using past data. However, when the reward model is not well-specified, the bandit algorithm may incur unexpected…

Each month, COVID-19 kills hundreds of thousands of people, reduces global gross domestic product (GDP) by hundreds of billions of dollars, and generates large, accumulating losses to human capital by harming education and health (…

The United States has invested more than $10 billion in Operation Warp Speed to fast-track SARS-CoV-2 vaccines from conception to market in 1 year. The result is 11…

Background 

The Stanford Biodesign Faculty Fellows program was established in 2014 to train Stanford Medical and Engineering faculty in a repeatable innovation process for health technology translation while also…

In medicine, randomized clinical trials are the gold standard for informing treatment decisions. Observational comparative effectiveness research is often plagued by selection bias, and expert-selected covariates may not be sufficient to adjust…

Alpha 1–adrenergic receptor blocking agents (α1-blockers) have been reported to have protective benefits against hyperinflammation and cytokine storm syndrome, conditions that are associated with mortality in patients with coronavirus disease…

Many studies document low rates of financial literacy and suboptimal levels of participation in financial markets. These issues are particularly acute among women. Does this reflect a self-reinforcing trap? If so, can a nudge to participate in…
