Price effects of calling out market power: A study of the COVID-19 oil price shock
Barkley A, Byrne DP and Wu X
Governments often make public announcements that call into question firms' misuse of market power. Yet little is known about how firms respond to them. We study gasoline retailers' price responses to antitrust announcements shaming them for price gouging during the COVID-19 pandemic. We identify price effects using a high-frequency event-study leveraging unique real-time station-level price data and well-identified, discrete antitrust announcements. We find evidence of announcement effects that depend on firms' preannouncement margins and hence exposure to being publicly shamed. Public statements by antitrust questioning firms' misuse of market power can indeed contain signals that affect equilibrium outcomes.

Integration and Task Allocation: Evidence from Patient Care
David G, Rawley E and Polsky D
Using the universe of patient transitions from inpatient hospital care to skilled nursing facilities and home health care in 2005, we show how integration eliminates task misallocation problems between organizations. We find that vertical integration allows hospitals to shift patient recovery tasks downstream to lower-cost organizations by discharging patients earlier (and in poorer health) and increasing post-hospitalization service intensity. While integration facilitates a shift in the allocation of tasks and resources, health outcomes either improved or were unaffected by integration on average. The evidence suggests that integration solves coordination problems that arise in market exchange through improvements in the allocation of tasks across care settings.
The impact of COVID-19 on small business owners: Evidence from the first three months after widespread social-distancing restrictions
Fairlie R
Social-distancing restrictions and health- and economic-driven demand shifts from COVID-19 are expected to shutter many small businesses and entrepreneurial ventures, but there is very little early evidence on impacts. This paper provides the first analysis of impacts of the pandemic on the number of active small businesses in the United States using nationally representative data from the April 2020 Current Population Survey-the first month fully capturing early effects. The number of active business owners in the United States plummeted by 3.3 million or 22% over the crucial 2-month window from February to April 2020. The drop in active business owners was the largest on record, and losses to business activity were felt across nearly all industries. African-American businesses were hit especially hard experiencing a 41% drop in business activity. Latinx business owner activity fell by 32%, and Asian business owner activity dropped by 26%. Simulations indicate that industry compositions partly placed these groups at a higher risk of business activity losses. Immigrant business owners experienced substantial losses in business activity of 36%. Female business owners were also disproportionately affected (25% drop in business activity). Continuing the analysis in May and June, the number of active business owners remained low-down by 15% and 8%, respectively. The continued losses in May and June, and partial rebounds from April were felt across all demographic groups and most industries. These findings of early-stage losses to small business activity have important implications for policy, income losses, and future economic inequality.
Competitive survival in a devastated industry: Evidence from hotels during COVID-19
Noel MD
In the face of COVID-19, the federal government scrambled to provide emergency funding to businesses, but did not always take into account the heterogeneous nature of firms, especially within industries. Using the lodging industry as the application, this article shows that businesses' failure risk in a pandemic depends on a business' native ability to adapt to changing safety needs, in particular its ability to provide a socially distanced environment. Hotels not well suited to social distancing-for example, destination-type hotels with large gathering spaces and many personalized services-offered deeper price discounts or closed down altogether during the pandemic. Simpler hotels with fewer ancillary services were more likely to remain open, with a substantial proportion actually increasing prices. Area infection rates mattered little. Effects are identified by comparing prepandemic expectations of outcomes to updated within-pandemic expectations of outcomes, all while holding the place and the time of consumption fixed.
Buyers' role in innovation procurement: Evidence from US military R&D contracts
Decarolis F, de Rassenfosse G, Giuffrida LM, Iossa E, Mollisi V, Raiteri E and Spagnolo G
This study provides the first quantification of buyers' role in the outcome of R&D procurement contracts. We combine together four data sources on US federal R&D contracts, follow-on patented inventions, federal public workforce characteristics, and perception of their work environment. By exploiting the observability of deaths of federal employees, we find that managers' death events negatively affect innovation outcomes: a 1% increase in the share of relevant public officer deaths causes a decline of 32.3% of patents per contract, 20.5% patent citations per contract, and 34.3% patent claims per contract. These effects are driven by the deaths occurring in the 6 months before the contract is awarded, thereby indicating the relevance of the design and award stage relative to ex post contract monitoring. Lower levels of self-reported within-office cooperation also negatively impact R&D outcomes.
How to Examine External Validity Within an Experiment
Kowalski AE
A fundamental concern for researchers who analyze and design experiments is that the estimate obtained from the experiment might not be externally valid for other policies of interest. Researchers often attempt to assess external validity by comparing data from an experiment to external data. In this paper, I discuss approaches from the treatment effects literature that researchers can use to begin the examination of external validity internally, within the data from a single experiment. I focus on presenting the approaches simply using stylized examples.
