Forget the Average—It’s the Top Students Who Drive National Innovation Progress
When it comes to a nation’s innovation and global competitiveness, what truly matters is how the top students perform, since they will play a disproportionate role in shaping the nation’s technological and economic edge. Policymakers should expand K-12 gifted and talented programs and provide high school students with more advanced and honors classes.

Innovative Resources Moving to Large Firms Likely Isn’t the Reason for Slowed Productivity Growth
Policymakers should not attempt to reallocate innovative resources from large to small firms. Instead, Congress should pass the Tax Relief for American Families and Workers Act of 2024 and expand the R&D tax credit. These measures will incentivize firms of all sizes to continue investing in productivity-enhancing and socially valuable R&D.
