The Productivity-Pay Gap in the Age of AI: Divergence, Dynamics, and Corrective Initiatives

I. Executive Summary

The persistent and growing divergence between productivity growth and the compensation of typical workers, commonly referred to as the productivity-pay gap, stands as a central challenge to equitable economic growth and shared prosperity.¹ This report examines the potential impact of Artificial Intelligence (AI) on this gap, with a particular focus on the analytical framework provided by the Economic Policy Institute (EPI). The EPI posits that this divergence, particularly evident since the late 1970s in the United States, is not an inevitable consequence of economic forces but rather the result of specific policy choices that have eroded the bargaining power of labor.²

The emergence of AI introduces a powerful new dynamic. AI technologies possess a dual capacity: they could exacerbate the existing productivity-pay gap by further concentrating economic gains and disempowering segments of the workforce, or, under appropriate policy and institutional frameworks, they could contribute to narrowing the gap by augmenting worker capabilities, democratizing skills, and fostering new avenues for value creation.³ The ultimate trajectory is not technologically predetermined but will be shaped by societal choices and interventions.

Currently, a range of initiatives are underway to navigate AI's impact. These include governmental policy and regulatory proposals, extensive workforce development programs spearheaded by public and private entities, corporate reskilling efforts, non-profit interventions aimed at equitable access and education, and strategic adaptations by labor unions seeking to protect worker interests in an AI-driven economy.⁵

This report concludes that AI's influence on the productivity-pay gap is contingent upon the policy environment in which it is deployed. Proactive, worker-centric policies, consistent with the EPI's recommendations for rebalancing labor market power, are crucial if AI-driven productivity gains are to translate into broadly shared prosperity.¹⁹ A coordinated strategy is essential to ensure that technological advancement aligns with the goals of reducing economic inequality and enhancing the well-being of the typical worker. The overarching consideration is that technology, including AI, operates within a socio-economic and policy framework; its effects are largely determined by this framework, not by its inherent characteristics alone.

II. The Productivity-Pay Gap: A Deep Dive into EPI's Analysis

A. Defining the Productivity-Pay Gap

The term "productivity-pay gap" specifically refers to the observed divergence between the growth of labor productivity and the growth of compensation for the typical worker.¹ Labor productivity is a measure of the economy-wide income generated per hour of work, reflecting the potential for rising living standards. "Pay" or "compensation" in this context, as defined by the Economic Policy Institute (EPI), encompasses the average wages and benefits of production and nonsupervisory workers. This group constitutes approximately 80% of the private-sector U.S. workforce, thereby representing the economic experience of the vast majority of workers, distinct from highly paid managerial and executive staff.²

It is important to distinguish this definition from other uses of the term "productivity gap." For instance, the term can also describe a sustained difference in measured output per worker (or GDP per person employed) between countries.²² Alternatively, it can refer to the "production gap," which is the difference between an economy's or organization's potential output and its actual output, highlighting inefficiencies.²³ While these broader concepts are relevant to overall economic performance, this report adheres to the EPI's specific definition, which focuses on the distributional question of how the fruits of increased efficiency are shared with the workforce.

B. Historical Divergence: Trends in Productivity vs. Compensation

The historical data presented by the EPI reveals a stark shift in the relationship between productivity and typical worker pay in the United States. For several decades following World War II, from 1948 until the late 1970s, the economic gains from rising productivity were broadly shared. During this period, the compensation of production and nonsupervisory workers grew in close alignment with net productivity growth.² Specifically, from 1948 to 1979, net productivity (economy-wide productivity net of depreciation) increased by 112.5%, while the real hourly compensation of a typical worker grew by a substantial 90.2%.²⁵ This near lockstep growth indicated that the economic system was effectively translating efficiency gains into improved living standards for the majority of the workforce.

However, a significant decoupling began in the late 1970s. According to updated EPI analysis covering the period from the fourth quarter of 1979 (1979q4) to the first quarter of 2025 (2025q1), net productivity grew by 86.0%. In stark contrast, the real hourly compensation for the typical worker increased by only 32.0% over this same extended period.²⁵ This means that productivity grew 2.7 times as much as pay for the median worker. An earlier analysis covering 1979 to 2019 showed an even wider divergence, with productivity up 85.1% and typical worker compensation up only 13.2%, a 3.5-fold difference.²⁵ This dramatic divergence underscores a fundamental shift in how economic gains have been distributed.

This period of decoupling also occurred within a broader historical context of fluctuating productivity growth rates. The post-World War II era saw significant productivity gains, which decelerated after 1973 but remained above earlier historical rates for many industrialized nations.²⁶ The United States experienced a productivity surge in the late 19th century and again in the mid-20th century, with real GDP per hour worked averaging almost 2.5% growth from 1913 to 1950.²⁶ The divergence identified by EPI thus represents a specific distributional phenomenon within these larger macroeconomic trends.

To illustrate this divergence clearly:

Period	Net Productivity Growth (%)	Typical Worker Hourly Compensation Growth (%)	Ratio of Productivity Growth to Pay Growth
1948–1979	112.5	90.2	1.25 : 1
1979q4–2025q1	86.0	32.0	2.69 : 1

C. EPI's Framework: Policy Choices and the Widening Gap

The EPI's central argument is that the widening productivity-pay gap is not an inevitable outcome of abstract economic forces like globalization or automation alone. Instead, it is primarily the result of a series of deliberate policy shifts enacted since the late 1970s that have systematically eroded the economic leverage and bargaining power of typical workers.²
