Long-Term Effects of the US Medical Research Effort During World War II
article
While US biomedical research funding generally allows researchers considerable freedom in determining the most promising topics to study, there have been some programs, such as the War on Cancer in the 1970s and Operation Warp Speed during the COVID-19 pandemic, that target funding at particular technologies or health objectives.
In The Therapeutic Consequences of the War: World War II and the 20th-Century Expansion of Biomedicine (NBER Working Paper 33457), Daniel P. Gross and Bhaven N. Sampat examine a historical precedent for top-down, targeted biomedical research. During World War II, when the high...

Policy Changes and Pharmaceutical Innovation Combine to Increase Naloxone Access
article
Naloxone, which reverses the effects of an opioid overdose, is a critical tool for responding to the opioid crisis. However, prior to the 2010s, two barriers hindered its widespread distribution and use in the United States. One was legal access: Naloxone required a prescription from a healthcare provider. Another was that naloxone was administered by injection and therefore required training for proper use.
In 2010, Illinois became the first state to adopt a dispensing naloxone access law (NAL) that permitted individuals to obtain naloxone directly from pharmacists, eliminating the need for an individual prescription. By 2015, another 35 states had implemented dispensing NALs. These policy initiatives were complemented by the introduction of Narcan, the first FDA-approved naloxone nasal spray, in 2016. This new…

Program Report: Corporate Finance
article
The NBER Corporate Finance Program has been a leading research forum in the field since it was established in 1991. Corporate finance questions intersect with many areas of finance and economics, including macrofinance, asset pricing, financial intermediation, and organizational economics. This breadth of topics is reflected in the work presented at the Corporate Finance program meetings. The importance of the field has been widely recognized in academia and is evidenced by the 2022 Nobel Memorial Prize in Economic Sciences for Ben Bernanke, Douglas Diamond, and Philip Dybvig’s work on banking and intermediation. In this report, we cannot do justice to the entire field, but we must select a few topics that have been addressed in a number of recent NBER Working Papers or in presentations at...

Immigrant Entrepreneurship in the US
article
Immigrants to the US are more entrepreneurial than the native population and overrepresented among high-growth startups and venture-backed tech firms. In Immigrant Entrepreneurship: New Estimates and a Research Agenda (NBER Working Paper 32400), Saheel Chodavadia, Sari Pekkala Kerr, William Kerr, and Louis Maiden use business surveys and administrative employment records to provide new evidence on the prevalence and predictors of immigrant...

When the US Army Corps of Engineers builds a levee, home prices in the area protected by it increase by an average of between 3 and 4 percent, but nearby homes in unprotected areas who face higher spillover flood risk fall in value by between 1 and 5 percent, Jacob T. Bradt and Joseph E. Aldy find.
Revolving door laws, which restrict former public officials from representing private interests before government, reduce the number of new candidates who campaign to serve in state legislatures, and increase incumbent retention by 3.1 percentage points, according to Raymond Fisman, Jetson Leder-Luis, Catherine M. O'Donnell, and Silvia Vannutelli.
A study of over 250,000 high school and 60,000 middle school students in New York City by Joshua Angrist, Peter Hull, Russell Legate-Yang, Parag A. Pathak, and Christopher R. Walters finds that survey data on school quality outperform test-based measures in predicting “school effects” on high school graduation rates. A one standard deviation higher school rating increases on-time high school diploma receipt by 11 percentage points.
Analyzing data from 1.6 million small US businesses, Ufuk Akcigit, Raman Singh Chhina, Seyit M. Cilasun, Javier Miranda, and Nicolas Serrano-Velarde find that monthly credit card payments by these firms are up to three times higher than loan payments. After the Federal Reserve’s interest rate hikes in early 2022, these businesses experienced a 16 percent decline in card balances, and a 10 percent drop in revenue growth.
In 2019, Louisiana’s Hepatitis C Elimination Plan implemented a “subscription model” for hepatitis C medications that capped state spending while providing unlimited access to treatment. The plan increased prescriptions by a factor of 2.5, while reducing hepatitis C-related mortality by about 12 percent, according to James M. Flynn, Bethany I. Lemont, and Barton Willage.
