Agentic Inequality: Dynamics & Metrics

Updated 25 October 2025

Agentic inequality is the systematic disparity in access, quality, and quantity of agents that drive power, opportunity, and socio-economic outcomes.
It is measured using metrics such as the Gini coefficient, Shannon entropy, and language agency levels to capture agent-based power distributions.
Mechanisms like network dynamics, homophily, and strategic interactions amplify these disparities, necessitating robust governance and policy interventions.

Agentic inequality refers to the systematic disparities in power, opportunity, and outcomes that emerge due to differential access to, and capabilities of, agents—especially autonomous AI agents—in social, economic, and political systems. Distinct from prior forms of technological inequality, agentic inequality is shaped by multifaceted factors: availability, quality, and quantity of agents, the specific mechanisms of agent interaction, network topology, reinforcement dynamics, and the sociotechnical and epistemic structures that mediate agency attribution. Contemporary research across economics, network science, AI, and digital sociology provides precise models, measurement tools, and foundational theory for understanding and managing agentic inequality.

1. Definitional Framework and Core Dimensions

The analytical foundation for agentic inequality is set by the triad of availability, quality, and quantity of agents (Sharp et al., 19 Oct 2025):

Availability: Binary access to a functional agent, not merely a raw foundation model.
Quality: Aggregate of agent intelligence, operational speed, robustness, tool-use capabilities, and behavioral disposition, represented by a mapping such as:

$Q = f(\text{Intelligence}, \text{Speed}, \text{Reliability}, \text{ToolUse}, \text{Disposition})$

Quantity: Simultaneous deployment of multiple agents, where scale can induce synergistic advantages (e.g., multi-agent negotiation, parallel task execution).

These dimensions are not independent; high agentic quality enhances the value of increased quantity, and vice versa. Such compounding effects create stratified levels of agentic power and outcome disparities, which are not captured by traditional measures like the digital divide (Sharp et al., 19 Oct 2025).

2. Dynamics of Inequality in Agent-Based and Networked Systems

Agentic inequality is inherently emergent: simple local rules and network interactions foster strong, persistent class divisions (Santalla et al., 2019). In models like the power accretion game, agents compete for resources proportional to their current power:

The probability of winning a round is $P_j = w_j / Z_i$ , where $Z_i$ is the sum of the powers in the active set. Victories yield multiplicative gains.
Geometric separation of high-class agents is enforced by network topology (e.g., in 1D rings, high-class agents are interposed by several low-class agents), yielding a stationary class stratification: high-class fraction $\sim 1/K$ (coordination number) (Santalla et al., 2019).

Agentic status, self-reinforcement, and network constraints thus jointly produce locked-in disparities, even from egalitarian initial conditions.

Several key mechanisms modulate agentic inequality:

Homophily: Preference for intragroup transactions amplifies both inter- and intra-group disparities. When connectivity bias $\delta$ favors group A, wealth flows preferentially to A and is internalized by high-connectivity agents, exacerbating internal inequality (Kohlrausch et al., 24 Feb 2025).
Protection Rules: Transaction biases (such as $p = ½ + f \cdot |\omega_i - \omega_j| / (\omega_i + \omega_j)$ ) favor poorer agents; higher $f$ (social protection factor) robustly reduces inequality, exceeding the effects of aggregate growth and redistribution (Villafañe et al., 8 Aug 2025). Asymmetric protection across groups induces wealth transfer and differential mobility (Dias et al., 30 Apr 2025).
Strategic Interaction: In game-theoretic, networked models, agents' strategic choices (cooperation, defection, tit-for-tat) and network structure drive distributional outcomes. Iterative, localized transactions can produce universal inequality patterns, measured by the Gini coefficient:

$G = \frac{1}{|V|} \sum_{i=1}^{|V|} (2i - |V| - 1)x_i$

where $x_i$ are sorted agent balances. The self-organization is robust to network details, with consistent peaks in inequality across diverse networks (Kejriwal et al., 22 May 2025).

4. Measuring Agentic Inequality: Metrics and Empirical Indicators

Agentic inequality is characterized through several complementary metrics:

Width/Roughness ( $W^2$ ): Variance of individual power from the average (Santalla et al., 2019).
Shannon Entropy ( $S$ ): $S = -\sum_i w_i \log w_i$ , reflecting effective participatory diversity.
Gini Index ( $G$ ) and Lorenz Curve ( $L(x)$ ): Capture relative concentration and distribution of agentic power.
Language Agency Level: In the context of LLMs, computed as $\text{Agency}(\%) = (\text{agentic sentences}) / (\text{total sentences}) \times 100$ (Wan et al., 16 Apr 2024).
Ratio Gap: Difference between percentages of agentic and communal language, uncovering demographic and intersectional disparities (Wan et al., 16 Apr 2024).

The simultaneous application of these metrics offers a comprehensive empirical lens, revealing both the scale and texture of agentic stratification.

5. Socio-Epistemic Structuration and Attribution of Agency

Agentic inequality is not solely a function of material conditions or network topology; it is fundamentally shaped by epistemic frameworks—ideologies, narratives, and social attribution models. The synthetic theory of socio-epistemic structuration formalizes outcomes ( $Y_i$ ) as a function of both economic connectedness ( $EC_i$ ) and internalized epistemic state ( $M_i$ ):

$Y_i = \beta_0 + \beta_1 EC_i + \beta_2 M_i + \beta_3 \sum_j w_{ij} M_j + \beta_4 \sum_j w_{ij} S_j + X_i'\gamma + u_i$

High "friending bias" ( $\varphi_i$ ) and epistemic friction constrain upward mobility and the translation of exposure into real agency. Agency is an attributed and socially granted status, not simply an inherent capacity (Salguero, 27 Sep 2025).

Reverse tutelage—subaltern publics challenging dominant epistemic frameworks—can contest and reshape the parameters of legitimate agency, thereby opening alternative pathways for empowered action.

6. Language, Representation, and AI Agency

AI agents, especially LLMs, encode and amplify agentic inequality not just through operational outcomes but also via representational biases:

Language Agency Bias: LLMs generate disproportionately agentic language for certain demographic groups (e.g., white males), while minority groups, particularly black females, receive lower agentic scores (Wan et al., 16 Apr 2024).
Mitigation Strategies: Post-processing methods—such as Mitigation via Selective Rewrite (MSR), using fine-tuned BERT classifiers—have demonstrated efficacy in reducing these disparities compared to prompt-based mitigation (Wan et al., 16 Apr 2024).
These findings indicate the need for rigorous auditing and intervention in both model design and deployment, as default generative systems tend to reinforce entrenched social biases.

7. Governance, Policy, and Future Research

Governance of agentic inequality presents multi-layered challenges (Sharp et al., 19 Oct 2025):

Normative Uncertainty: What constitutes a "fair" distribution of agentic power is context-contingent and underdetermined by current frameworks.
Regulatory Pacing and Fragmentation: The technological evolution of agentic systems outpaces regulatory adaptation, risking entrenchment of disparities before interventions can be developed.
Public Service Models and Technical Standards: Proposals such as "universal basic agency" and open protocol standards offer potential for democratizing agentic power, provided resource allocation and infrastructure are managed to balance innovation and accessibility.
Robust Metrics and Empirical Foundations: The field calls for comprehensive measurement strategies and empirical paper of agentic disparities across real-world deployments and demographics.

Further research is needed into alignment, interpretability, cross-border regulatory frameworks, and participatory design of agentic AI systems to ensure equitable distribution of capabilities and outcomes.

Agentic inequality emerges from the interaction of agent availability, quality, and quantity; network and social reinforcement mechanisms; epistemic attribution and cultural norms; and the representational strategies of AI systems. Its paper and mitigation require interdisciplinary rigor—combining formal modeling, empirical measurement, structural policy, and epistemic critique—to prevent the amplification of existing divides and to design agentic systems as tools for equalisation rather than stratification.
