In new research, evidence from a land titling campaign in the Democratic Republic of Congo shows that formal property rights can do more than secure land: they can give citizens an exit from costly informal obligations, writes Pablo Balán.

In new research, Cailtin K. Myers and Ezekiel Hooper find that birth rates in the United States have declined as a result of the introduction of the iPhone. They theorize that the smartphone is crowding out the market for attention, offering a device to fill users’ time that replaces forming in-person relationships that typically create children. 

In a new paper, Joseph Emmens, Dennis C. Hutschenreiter, Stefano Manfredonia, Felix Noth, and Tommaso Santini find that when competitors for the same pool of workers share investors, they increase their innovation to automate tasks and slow down hiring.    

In new research for the Foundation for Individual Rights and Expression, David M. Primo uses campaign contribution data to show that professors at leading universities are more politically active than the average American and skew heavily to the left politically, raising concerns about the diversity of perspectives on college campuses.    

In new research, Semih Üslü and Flavien Moreau argue that waves of mergers and acquisition, which are typically unstable and ultimately crash, are not driven by changes in economic conditions, but by self-reinforcing appetite for mergers among firms when others are also engaging in M&A. Policies that drive stable, low-merger conditions can lead to better outcomes for consumers.

The OxyContin epidemic had large demographic effects on communities in the United States. In new research, Carolina Arteaga, Victoria Barone, and Stephen Claassen find that Purdue Pharma’s marketing strategy targeted specific areas, causing college-educated residents to flee and increasing fertility rates among the most affected populations.

In a new working paper, Benjamin Verschuere and Angus Cameron argue that the wide dispersion in economists' forecasts for the impact of artificial intelligence on the economy stems from two gaps. The first is that estimates for growth, jobs, and prices are each built in isolation, with no single framework to reconcile them. The second is that models fixate on AI’s current capabilities, rather than on how fast it spreads and how much of a given job it can eventually reach. The authors build a unified framework that predicts roughly $2 trillion in long-run output gains, the loss of about 20 million American jobs, and falling prices.

The Supreme Court's decision in Trump v. Slaughter strips independent agencies of removal protections that made regulatory policy predictable across administrations. In new research, Brian Feinstein and Daniel Hemel find that equity markets assign real value to precisely that kind of insulation.

In new research examining 44 million U.S. mortgages and nearly 5,000 bank mergers over three decades, Celso Brunetti, Jeffrey H. Harris, and Ioannis Spyridopoulos find that bank consolidation does not raise mortgage rates, restrict credit access, or degrade loan quality. Local mortgage markets remain intensely competitive. 

The United States healthcare system has experienced an expansion of private equity ownership. In new research, Theodosia Stavroulaki argues that private equity acquisitions risk harming healthcare by increasing prices, reducing quality of care, limiting access to care, and hurting the labor force.
