In a new study, Jim Albertus at Carnegie Mellon University evaluated the impact of tax incentives on foreign-owned U.S. businesses’ income shifting, employment, and investment decisions. He found that foreign multinational firms engage in a modest degree of tax-motivated income shifting out of the United States. The results inform the potential effects of the “Revenge Tax” provisions of the June 2025 tax bill under consideration in the U.S. Congress.

Low-income students who received a preschool intervention focused on social-emotional development continued to benefit from it during their teen years according to a recent study published in the journal Child Development. The researchers, led by Karen Bierman, Evan Pugh University Professor of Psychology and Human Development and Family Studies at Penn State, found that their Head Start Research-based, Developmentally Informed (REDI) intervention improved students’ behavior and mental health during high school.

A new study finds that preteens with addictive patterns of social media, video games, or mobile phones use are more likely to experience worse mental health and suicidal thoughts and behaviors. 

About The Study: This study identified distinct trajectories of addictive use of social media, mobile phones, and video games from childhood to early adolescence and found links to suicidal behaviors, suicidal ideation, and worse mental health outcomes. High or increasing addictive use trajectories were common. Addictive screen use trajectories warrant further study regarding potential use for clinical evaluation of risk and for the design and testing of interventions to improve youth mental health.

New research found that youth who become increasingly addicted to social media, mobile phones or video games are at greater risk of suicidal thoughts, suicide attempts and emotional or behavioral issues. The study, published June 18 in JAMA, was led by researchers at Weill Cornell Medicine, Columbia University and University of California, Berkeley.
