When More Means Less: Navigating The Risks Of A U.S. Productivity Boom

The latest U.S. productivity numbers have delivered an unexpected jolt. 3Q data revealed a large upside surprise, with output per hour rising above expectations. In theory, this should be great news: firms are doing more with less, a marker of economic vitality. Yet, the reality is more complex—and potentially troubling for the U.S. workforce.

Recent Trends.The U.S. corporate sector is achieving more with fewer hands. Even as productivity rises, hiring remains subdued. This divergence signals that businesses are squeezing greater efficiencies from existing resources, rather than expanding payrolls. With labor markets already showing signs of slack, the question arises: are we witnessing the birth of a new era of “lean growth”?

Historical Perspective: From Slow Lane to Fast Track.Since the financial crisis, U.S. productivity growth has averaged a modest 1.5% annually. Over the past five years, that figure has crept up to around 2%—a clear improvement, but one that still lags the heady days of the late 1990s. Back then, tech-driven gains propelled productivity growth to 3-4%, fundamentally reshaping the economic landscape. Today, rapid advances in AI and automation hint at a possible return to those heights. The question is whether the broader economy—and its workers—are prepared for the consequences.

Tech’s Role: A Double-Edged Sword.The tech sector remains the engine of productivity acceleration. Machine learning, robotics, and cloud computing innovations are enabling firms to amplify output with labor costs steady or even lower. If this persists, 3-4% annual productivity growth could become the new normal. But history suggests that such booms are rarely unalloyed blessings. The late 1990s saw robust job creation; today, the same forces may instead reinforce labor market bifurcation.

Labor Market Implications: The Unit Cost Conundrum.

Rising productivity, coupled with constrained wage gains, is driving down unit labor costs. This is good news for profit margins, but less so for workers whose wages lag behind. The real test will be whether these efficiency gains translate into broad-based employment growth. If not, the U.S. risks a “tepid recovery,” with profits outpacing wage growth by up to fourfold—a scenario that could exacerbate inequality and dampen consumer demand.

Key Question: Can Productivity Power Job Growth?

Productivity sets the speed limit for the economy. Sustained upside surprises are welcome, provided they are matched by robust job creation and rising incomes. If, however, the current trajectory persists—where firms grow more efficient without expanding their workforce—the U.S. may find itself in a jobless recovery, where the spoils of growth accrue disproportionately to capital over labor.

We introduced a new macro scenario to our outlook, in which tax cuts and deregulation more than offset the effects of tariffs and tighter immigration policies. In this environment, robust productivity gains persist, supporting strong economic growth without triggering higher inflation.
