We introduce a novel measure of corporate hierarchies for over 2,500 U.S. public firms. This measure is obtained from online resumes of 16 million employees and a network estimation technique that allows us to identify hierarchical layers. Equipped with this measure, we document several facts...

This paper examines firm ownership structures in competitive general equilibrium by introducing a model where ownership rights emerge endogenously rather than being assumed. By embedding the property rights theory of the firm into general equilibrium analysis, the model demonstrates how market...

The field of international trade has undergone significant theoretical and empirical advancements over the last twenty-five years. A key breakthrough has been the emergence of firm-level approaches to studying exporting, importing, and global value chains. The field has also experienced a...

With the goal of lowering incentives for alcohol and substance abuse, U.S. states have historically permitted private health insurers to deny reimbursement of medical claims stemming from alcohol or opioid impairment. However, a potential unintended consequence of such "exclusion provisions" is...

Using data on prescriptions for cholesterol-lowering drugs (statins), we study differences in the treatments chosen by Danish physicians for themselves versus for their patients. We estimate that physicians discount patient health benefit relative to their own, valuing the additional potency of...

This paper examines a new moral hazard in delegated decision-making: authors can embed hidden instructions--known as prompt injections--to bias AI referees in academic peer review, thereby hijacking machine recommendations. Because AI reviews are relatively inexpensive compared to manual...

This paper studies the misallocation of Medicaid funds, its consequences for reimbursement rates, the quantity, and the quality of care provided. Combining two decades of administrative, audit, and survey data on U.S. nursing homes, we show that states employ creative financing schemes to divert...

Health insurance lowers the out-of-pocket price of healthcare, and it is well-established that this leads to higher utilization of care. This type of "moral hazard" is typically viewed as a social cost of insurance. Within a standard model, we show that there are two important ways in which the...

Spending induced by health insurance is often called moral hazard and definitionally assumed to be inefficient. We adapt standard models and show that for those living "hand-to-mouth", the financing benefits of insurance cause a portion of moral hazard to be efficient. Although insurance's price...

We investigate the factors driving workers' decisions to generate public goods inside an organization through a randomized solicitation of workplace improvement proposals in a medical center with 1200 employees. We find that pecuniary incentives, such as winning a prize, generate a threefold...
