We measure the impacts of vertical integration between insurers and hospitals. In the Chilean market, where half of private hospital capacity is vertically integrated, integration increases inpatient care spending by 6 percent and decreases consumer surplus and total welfare. Integrated insurers...

The Covid-19 pandemic represents one of the most significant labor market shocks to the world economy in recent times. We present evidence from a field experiment to understand whether and why skilled and unskilled workers were differentially impacted by the shock, in the context of a low-income...

Empirical research in public economics, including our own, often uses variation in state and local taxes as an empirical laboratory to estimate causal relationships. A key concern is that other taxes might change at the same time. To assess this concern, we develop a dataset of state (1977-2022)...

Doctors facing similar patients often make different treatment choices. These decisions can have important effects on patient health and health care spending. This paper seeks to organize the recent economics literature on physician decision making using a simple model that incorporates doctor...

We provide new evidence on the causal effect of unearned income on consumption, balance sheets, and financial outcomes by exploiting an experiment that randomly assigned 1000 individuals to receive $1000 per month and 2000 individuals to receive $50 per month for three years. The transfer...

We examine the rise of cloud computing and AI in China and their impacts on industry dynamics after the shock to the cost of Internet-based computing power and services. We find that cloud computing is associated with an increase in firm entry, exit and the likelihood of M&A in industries that...

When obtaining information on individuals' race and ethnicity, the Current Population Survey (CPS) currently follows the 1997 OMB standards, which prescribes race and Hispanic ethnicity as distinct concepts that should be asked about in separate questions. In 2024, OMB updated the standards to...

We present a dynamic two-country model in which military spending, geopolitical risk, and government bond prices are jointly determined. The model is consistent with three empirical facts: hegemons have a funding advantage, this advantage rises with geopolitical tensions, and war losers suffer...

Bank distress was a defining feature of the Great Depression in the United States. Most banks, however, weathered the storm and remained in operation throughout the contraction. We show that surviving banks cut lending when depositors withdrew funds en masse during panics. This panic-induced...

We consider the optimal policy problem of a benevolent planner, who is uncertain about an individual's true preferences because of inconsistencies in revealed preferences across behavioral frames. We adapt theories of expected utility maximization and ambiguity aversion to characterize the...
