Bullough: Without better productivity won't see 2.5-3* growth

Productivity Growth Critical to Achieving Higher Long-Term GDP Expansion

The U.S. economy has struggled to return to robust growth since the 2009 recession, with real GDP expanding at an average annual rate of 2% over the past seven years—well below the 3% to 4% seen in prior expansions according to St. Louis Fed analysis. Experts emphasize that without significant improvements in productivity, sustained growth above 2.5–3% remains unlikely. Productivity growth, which measures output per worker, has averaged just 0.4% annually since 2013, a sharp decline from the 2.3% average during the 1995–2005 period according to St. Louis Fed analysis.

Monetary policy, while useful for short-term stabilization, cannot permanently elevate long-term growth rates. Economic theory underscores that monetary interventions are neutral over time, merely redistributing growth rather than creating new output according to St. Louis Fed analysis. This underscores the need to focus on structural factors driving productivity. Three key determinants emerge from economic literature: technological innovation, human capital development, and investment in productive public infrastructure.

Technological advancements—such as the historical adoption of electricity or the internet—have historically spurred productivity gains by transforming industries. However, the diffusion of new technologies across sectors remains uneven according to St. Louis Fed analysis. Simultaneously, human capital development, including workforce training and education, is critical to aligning skills with evolving economic demands. Finally, public infrastructure—roads, broadband, and energy grids—plays a foundational role in enhancing private-sector efficiency according to St. Louis Fed analysis.

Policymakers face a clear challenge: fostering an environment where these factors can thrive. Encouraging R&D investment, streamlining technology adoption, and prioritizing infrastructure modernization could lay the groundwork for stronger growth. Without such measures, the U.S. risks remaining trapped in a low-productivity, low-growth equilibrium. As the economy approaches 2030, the urgency to act grows—productivity is not just a technical term, but a prerequisite for improving living standards and securing long-term prosperity according to St. Louis Fed analysis.
