The Augmentation Trap: AI Productivity and the Cost of Cognitive Offloading

Published 3 Apr 2026 in cs.HC and cs.AI | (2604.03501v1)

Abstract: Experimental evidence confirms that AI tools raise worker productivity, but also that sustained use can erode the expertise on which those gains depend. We develop a dynamic model in which a decision-maker chooses AI usage intensity for a worker over time, trading immediate productivity against the erosion of worker skill. We decompose the tool's productivity effect into two channels, one independent of worker expertise and one that scales with it. The model produces three main results. First, even a decision-maker who fully anticipates skill erosion rationally adopts AI when front-loaded productivity gains outweigh long-run skill costs, producing steady-state loss: the worker ends up less productive than before adoption. Second, when managers are short-termist or worker skill has external value, the decision-maker's optimal policy turns steady-state loss into the augmentation trap, leaving the worker worse off than if AI had never been adopted. Third, when AI productivity depends less on worker expertise, workers can permanently diverge in skill: experienced workers realize their full potential while less experienced workers deskill to zero. Small differences in managerial incentives can determine which path a worker takes. The productivity decomposition classifies deployments into five regimes that separate beneficial adoption from harmful adoption and identifies which deployments are vulnerable to the trap.

  • Key findings suggest that adjusting managerial evaluation horizons and direct skill measurement can mitigate welfare-reducing deskilling.

The Augmentation Trap: AI Productivity and the Cost of Cognitive Offloading

Introduction

"The Augmentation Trap: AI Productivity and the Cost of Cognitive Offloading" (2604.03501) delivers a theoretical analysis of how sustained AI usage affects individual worker expertise under differing incentive structures. The work formalizes the tradeoffs between short-term productivity enhancements from AI augmentation and the long-term erosion of domain-relevant skill, providing a dynamic framework that elucidates when, how, and for whom AI adoption becomes a net liability rather than an asset due to cognitive offloading. Crucially, the framework identifies regimes where rational, fully informed decision-makers willingly enter a loss in steady-state productivity, and it characterizes the organizational, economic, and workflow-level parameters that mediate this phenomenon.

Model Overview

The central construct is a continuous-time dynamic model where an organizational decision-maker controls AI usage intensity for a worker over time. The per-period productivity function separates the effects of AI into (i) a skill-neutral term (α\alpha) representing productivity gain independent of user expertise (e.g., automated data translation), and (ii) a knowledge-complementary term (β\beta), scaling linearly with human skill, reflecting scenarios where human expertise is necessary to direct, evaluate, or improve AI output (e.g., brainstorming with LLMs on judgment-intensive tasks). Usage yields immediate productivity gains but atrophies human skill by reducing engagement with core, expertise-forming activities.

Skill dynamics are governed by a standard learning-forgetting formulation: Direct practice without AI leads to skill accumulation toward a potential Sˉ\bar S, while reliance on AI causes skill depreciation. The discount rate (δ\delta) distinguishes the horizon of the decision-maker from that of the worker, systematically linking temporal myopia with overuse of AI and subsequent skill loss.

Main Analytical Results

The model yields several strong and sometimes contradictory predictions:

  • Steady-State Loss under Rational Adoption: Even a fully informed, welfare-maximizing decision-maker may rationally choose to use AI at an intensity that produces lower long-run productivity than the pre-AI baseline, if the discounted sum of immediate AI-induced productivity boosts exceeds future skill loss. This outcome, analytically demonstrated, challenges the assumption that rational adoption ensures long-term improvement—front-loaded gains can systematically incentivize decaying expertise and eventual suboptimal steady states.
  • The Augmentation Trap and Incentive Misalignments: When the policy-setting agent (e.g., a manager) is more short-term oriented (higher δ\delta) than the worker, or if the worker places nontrivial external value on their enduring skill (e.g., labor mobility, pro mastery, or community status), overuse of AI intensifies. The boundaries—characterized in closed form in the (α,β)(\alpha, \beta) parameter space—between beneficial and harmful adoption enlarge, turning steady-state loss from a privately rational but self-harming decision into a true welfare trap for the employee demographic or occupation.
  • Complementarity Versus Substitution and Permanent Skill Divergence: For tasks and workflows where the AI’s productivity is weakly dependent on user expertise (low β\beta), the model predicts structural divergence: low-skill workers deskill rapidly, becoming fully reliant on AI, while high-skill workers can preserve and continue to develop their expertise through limited AI engagement. This stratification is non-transient and suggests that AI can entrench or reinforce inequality in human capital formation, with direct implications for STEM pipeline management and professional development.

Empirical and Theoretical Implications

The model aligns with emerging empirical evidence: longitudinal studies show that sustained AI use erodes domain skills ("intuition rust" among medical professionals [Ehsan et al., 2026]; knowledge retention deficits in students using LLMs [Barcaui, 2025]; neuroimaging studies of deskilling [Patra et al., 2025], [Shen and Tamkin, 2026]). Existing randomized controlled trials show that workers' benefit from AI varies by baseline expertise and workflow structure. The decomposition into (α,β)(\alpha, \beta) clarifies observed heterogeneity in outcomes, e.g., skill-levelling versus skill-biased effects.

On the theoretical side, the analysis shows robustness under various generalizations of the productivity and skill adjustment laws. Feedback loops (positive in the substitution regime, negative in the complementarity regime) endogenously drive convergence or bifurcation in workforce skill dynamics, with clear links to automation bias literature and post-adoption drift (i.e., β\beta erosion via passive acceptance over time).

Organizational Policy Prescriptions and Design Levers

The authors highlight multiple organizational levers for avoiding the augmentation trap:

  • Measuring Skill, Not Just Output: As AI increases output without necessarily preserving skill, organizations must implement direct skill measurement (e.g., unassisted task assessments, reasoning explainability requirements) to gauge whether the long-run effect is beneficial.
  • Training and Recovery (κ\kappa): Higher rates of recovery (e.g., enforced unassisted practice, structured workflows prioritizing skill development in early career stages) proportionally shrink conditions for the trap. Deliberate workflow design—delaying wide-scale AI deployment for skill formation periods—mitigates deskilling, especially for new entrants.
  • Evaluation Horizons (β\beta0): Tying managerial performance incentives to long-term workforce capability instead of short-term output closes the wedge driving overuse; this includes bonus structures contingent on downstream outcomes, which could be operationalized via vesting schemes.
  • Workflow Design (β\beta1): Shifting workflows towards knowledge complementarity—using AI to scaffold but not substitute complex reasoning tasks—raises β\beta2 and shrinks the trap region. Example interventions include draft-then-revise processes, graduated autonomy, reasoning chain exposure, and mandatory pre-AI independent reasoning. These practices trade short-run output for long-term skill retention, counterbalancing organizational discounting bias.

Testable Predictions

The framework yields several falsifiable hypotheses:

  • Overreliance on AI should predict diminished independent task performance over time, observable during AI outages or controlled withdrawals.
  • Adoption patterns (by baseline skill and job complexity) should predict long-run skill divergence in low-complementarity (high-β\beta3, low-β\beta4) sectors.
  • Organizations with high turnover and shorter evaluation periods should display steeper productivity-skill divergence trajectories.
  • Random assignment of longer managerial evaluation horizons or direct skill measurement regimes should contract AI overuse and steady-state loss.

Limitations and Future Directions

While the current model intentionally abstracts many practical complexities for analytical tractability—single-skill dimension, fixed task parameters, exogeneity of β\beta5—these restrict applicability to workplaces with static roles. Real-world AI deployments may also catalyze skill recomposition (e.g., prompt engineering, AI evaluation skills versus traditional domain practice) not modeled herein. Furthermore, labor market equilibria with externalities (e.g., aggregate loss of judgment skills economy-wide) and evolution of AI workflows are not formally incorporated, though the authors suggest these are essential directions (cf. [Acemoglu et al., 2026]).

Conclusion

This work provides a formal, operational typology of AI productivity regimes, demonstrating analytically that rational reliance on AI can result in organizational and societal traps via cognitive deskilling. It identifies structural features—both behavioral (e.g., discount rates, externalities) and technological (complementarity parameters)—driving stable, welfare-reducing equilibria. The augmentation trap is not an immutable characteristic of AI, but a function of deployment regimes and incentive and governance structures. This work compels practitioners to move beyond surface-level output assessments toward strategic adoption protocols that internalize long-term human capital effects.

Development of robust diagnostic and evaluation frameworks for workflow-level consequences is necessary to mitigate unrecognized downstream harms, with immediate relevance for high-stakes, knowledge-intensive professions. Implementing the insights from this model could directly inform policy at the organizational and sectoral level, influencing the configuration of “pro-worker” AI systems and resilient expertise pipelines.

What this paper is about (big picture)

This paper asks a simple but important question: What happens to people’s skills when they use AI tools a lot to help with their work? The authors show that while AI can make you faster today, using it too much can quietly weaken the very skills that made you good in the first place. They call this danger the “augmentation trap.”

What questions the authors wanted to answer

In everyday terms, the paper tackles questions like:

  • How much should a person (or their manager) rely on AI each day to get the most done now without ruining their skills later?
  • When does using AI make people better off in the long run, and when does it leave them worse off than if they never used AI at all?
  • How does the way we use AI—whether it needs human judgment or runs mostly on its own—change who benefits and who falls behind?
  • How do short-term-focused managers or companies push workers into bad long‑run outcomes?

How they studied it (in simple language)

Instead of running a short experiment, the authors build a “dynamic model,” which is like a long-term simulation that tracks two things over time:

  1. Your skill level (call it S): This grows when you practice and shrinks when you offload thinking to AI—like muscles that strengthen with use and weaken with disuse.
  2. How much you use AI each day (call it u, between 0 and 1): Higher u means more AI help today, but less practice for you, which can reduce tomorrow’s skill.

They also split AI’s helpfulness into two parts:

  • Alpha (α): The part of AI’s boost that doesn’t depend on your skill—think of a tool that works pretty well no matter who uses it (like auto-translation of simple phrases).
  • Beta (β): The part that depends on your expertise—tools that become much more powerful in skilled hands (like asking sharp, expert prompts to get better answers).

Key idea: The same AI tool can have different α and β depending on how you use it. If you let AI do most of the work (templates, auto-complete), α is high and β is low. If you use AI as a thinking partner (critiquing, steering, checking), β is high and α is lower.

They also include realistic forces:

  • Diminishing returns (γ): The easiest tasks get automated first.
  • Learning/forgetting rate (κ): How quickly skills grow with practice or decay without it.
  • Discount rate (δ): How much a decision-maker values the future versus the present (impatient managers care more about today’s output than future skill).

Using this setup, they simulate what happens to skill, output, and AI usage over months and years.

What they found (main results)

Here are the main takeaways, explained plainly.

  1. Short‑term gains can hide long‑term losses
  • Even if managers fully understand that skills will erode, it can still be rational to adopt AI because the early productivity boost is big.
  • But in some cases, the worker ends up in a worse steady state—producing less than before AI—once their skills decay. In other words: win now, lose later.
  1. The “augmentation trap” appears when incentives are misaligned
  • If managers focus on short-term output (high δ) or don’t value the worker’s broader skill (e.g., the worker cares about transferable skills, but the firm doesn’t), they choose higher AI usage than the worker would choose for themselves.
  • That can push the worker into the augmentation trap: they’d actually have been better off if AI had never been adopted in their workflow.
  1. How AI is used matters: five deployment “zones” The model sorts AI use into five regions based on α and β (remember: that’s about usage design, not the tool itself).
  • Non‑adoption: AI isn’t worth using.
  • Augmentation, worse‑off: AI helps now but leaves the worker worse off in the long run.
  • Automation, worse‑off: AI replaces the human, skill drops to zero, and long‑run outcomes are worse than no AI.
  • Augmentation, better‑off: AI plus human judgment strengthens the worker’s long‑run position.
  • Automation, better‑off: AI alone is clearly better than a human’s best (e.g., repetitive data entry).

High‑β (human‑in‑the‑loop) designs are more likely to land in “better‑off” zones because skill still matters and is worth maintaining. Low‑β, high‑α designs are more likely to land in “worse‑off” zones because the tool works fine without human judgment, so people stop practicing and skills fade.

  1. Who uses AI more depends on β
  • If β > 1 (AI complements skill): more skilled workers use AI more, but because their judgment matters, they keep engaging and their skills are less likely to atrophy badly.
  • If β < 1 (AI levels skills by substituting for them): less skilled workers use AI more, which can speed up their skill decay because they practice less.
  1. Skill “K‑curve”: permanent divergence can happen
  • In some low‑β setups, the team splits: experienced workers use AI sparingly and reach full potential; less experienced workers lean hard on AI, stop practicing, and their skills can decay toward zero.
  • Tiny differences in incentives (like a manager with a shorter time horizon) can tip someone from the “improving” side to the “declining” side.
  1. Stopping AI isn’t an instant fix
  • If someone stops using AI, skills recover slowly (like muscles after time off). Recovery can take years in fields where expertise builds slowly.

Why this matters (practical impact)

This research says the long‑run effects of AI depend less on the model itself and more on how we design and govern its use. Here’s why it matters:

  • For students and learners: If you always let AI do the thinking, you’ll learn less and retain less. To grow your abilities, use AI as a coach, not a crutch—ask it to explain, critique, or debate rather than just give answers.
  • For workers: Be mindful of how much you offload. If your role relies on judgment (writing, coding, diagnosis, analysis), staying mentally “in the loop” protects your future skill and career options.
  • For managers: Short‑term gains can backfire by degrading your team’s capability. Design workflows that keep human judgment central (raise β), and set goals that encourage engagement, not blind acceptance. Otherwise, you risk trapping your team in lower long‑run productivity.
  • For organizations and policymakers: Incentive design matters. If evaluations reward only immediate output, you’ll push people toward over‑automation and skill decay. Consider training time, rotation off AI, or metrics that value skill development and error‑checking.
  • For tool designers: Features that require human critique, comparison, and explanation (higher β) are safer for long‑run skill than one‑click automation (high α, low β).

A few friendly analogies to remember

  • Training wheels: Great for balance at first, but if you never ride without them, you don’t learn to steer on your own.
  • Calculators in math class: Useful for speed, but if you never practice the steps, you forget how to solve problems yourself.
  • Muscles: Use them and they grow; stop using them and they shrink. AI can be a treadmill (helps you train) or a moving walkway (carries you along while your muscles weaken), depending on how you use it.

Bottom line

AI can make us faster today, but how we use it decides whether we get smarter or duller tomorrow. If AI is embedded in ways that keep human judgment active (high β), it can truly augment us. If it removes the need to think (high α, low β), it can quietly automate our decline. Thoughtful design, aligned incentives, and deliberate practice are the difference between a boost and a trap.

Knowledge Gaps

Knowledge gaps, limitations, and open questions

Below is a single, concrete list of what remains missing, uncertain, or unexplored in the paper, framed to guide actionable future research:

  • Empirical identification of the productivity decomposition: how to measure and estimate the skill‑neutral channel (α) and the knowledge‑complementary channel (β) for real workflows, teams, and tasks.
  • Endogenous drift in usage practice: modeling and measuring how β (and α) evolve over time as users become familiar with AI and potentially disengage (automation bias), including feedback from policy to β.
  • Learning from AI vs. displacement: extending skill dynamics to allow for positive learning while using AI (e.g., reflective use, scaffolding, tutoring modes) rather than assuming all usage displaces practice.
  • Asymmetric and non‑linear learning/forgetting: testing whether κ differs for learning vs. forgetting, whether decay is non‑linear (e.g., thresholds, spacing effects), and how this changes trap boundaries.
  • Stochastic environments: incorporating uncertainty in task difficulty, AI performance variability, and shocks to S(t) or p(S,u) and assessing robustness of steady‑state and stratification results.
  • Heterogeneity and distributional dynamics: allowing worker‑level variation in κ, α, β, γ, and potential Sˉ\bar S and deriving population‑level implications for skill inequality and mobility.
  • Multi‑task portfolios: modeling roles composed of diverse subtasks with different (α,β,γ), and studying cross‑task spillovers and optimal allocation of AI usage across a task portfolio.
  • Team and organizational production: extending to multi‑worker settings (peer effects, supervision structures) where one worker’s usage affects others’ learning opportunities and outcomes.
  • Market equilibrium effects: analyzing how widespread adoption feeds back into labor supply of expertise, wages, turnover, and firm training investments (general vs. specific human capital).
  • Dynamics of AI progress: treating α and β as time‑varying with exogenous (or endogenous) technological improvement, and characterizing how tool improvements shift trap regions over time.
  • Workflow design as a control lever: endogenizing the choice of interaction pattern (prompting, review protocols, gated autonomy) to target desirable (α,β) and preserve learning.
  • Measuring and pricing risk: adding error costs (e.g., hallucinations, rare catastrophic mistakes), liability, and quality penalties to the productivity function and reassessing optimal usage.
  • Observability and control: allowing imperfect measurement of worker skill S and usage u, shadow IT, and enforcement frictions; designing contracts and monitoring that can implement optimal policies.
  • Worker agency and strategic behavior: modeling bargaining, opt‑out, covert usage, and career choice responses to mandated policies, and how these re‑shape long‑run skill trajectories.
  • Calibrating discount rates: empirically estimating managers’ and workers’ effective discount rates (δF, δW) and quantifying how realistic gaps map to trap prevalence in field settings.
  • Valuing skill externalities (ω): measuring the private value of skill outside firm output (mobility, reputation, side projects) across occupations and geographies to parameterize ω.
  • Intervention design and evaluation: deriving and testing concrete policies (practice quotas, rotating “no‑AI” intervals, graduated autonomy, skill‑conditional usage caps) that minimize trap risk.
  • Skill‑aware tool features: exploring AI designs (e.g., tiered assistance, “explain first” modes, delayed answers, reflective prompts) that maintain high β while preserving learning gains.
  • Onboarding and career‑stage policies: tailoring usage policy by seniority to prevent early‑career deskilling while still capturing productivity gains for experienced workers.
  • Measurement protocols for skill atrophy: specifying longitudinal metrics, testing intervals, and telemetry needed to detect and attribute skill loss to AI usage in production environments.
  • Identification strategies: designing long‑horizon randomized deployments or natural experiments that can causally estimate long‑run effects (including post‑trial washout) beyond short‑run RCTs.
  • Robustness to alternative functional forms: testing whether core results persist under CES or non‑quadratic productivity, alternative diminishing returns, and different skill laws of motion.
  • Path dependence and multiple equilibria: mapping conditions for non‑convexities, basin switching, and hysteresis when α, β, or policies change, and how small shocks trigger regime shifts.
  • Costs of AI usage and access constraints: introducing per‑use costs, compute limits, and downtime and re‑optimizing policies under budget constraints.
  • Safety, compliance, and regulatory frictions: modeling mandatory oversight or audit requirements and how they alter optimal u and long‑run skill outcomes.
  • Cross‑domain external validity: testing whether proposed regimes/thresholds translate from programming/writing to high‑stakes domains (medicine, law, engineering) with different error costs.
  • Equity and fairness: examining how initial skill differences interact with policy to produce persistent stratification across demographics; designing equitable mitigation strategies.
  • Spillovers to AI improvement: assessing whether reduced human practice degrades feedback/label quality needed for future AI training and the long‑run co‑evolution of human and AI capability.
  • Data and reproducibility: assembling open datasets (usage logs, code reviews, outcomes) and releasing code to replicate region maps and transition dynamics with realistic parameters.
  • Practical boundary conditions: clarifying how switching costs, retraining investments, task re‑design costs, or institutional constraints alter adoption thresholds and trap regions.

Notes on Assumptions and Dependencies (Cross-Cutting)

  • Measurement: Many applications depend on estimating skill SS, usage uu, and productivity over time. Proxies (e.g., unaided assessments, calibration tasks) must be validated and privacy-preserving.
  • Culture and Incentives: Success requires aligning incentives (managerial discount rate δF\delta_F vs. worker’s δW\delta_W) and recognizing private returns to skill (ω\omega).
  • Tooling: Vendors need to expose controls and telemetry to manage uu and to build high-β\beta interactions.
  • Legal/Compliance: In regulated domains, changes may require new guidance, standards, and audit regimes.
  • Heterogeneity: The same model can yield different (α,β)(\alpha,\beta) depending on workflow embedding; pilots are necessary before broad rollout.

Glossary

  • Adoption threshold: The minimum parameter value at which adopting AI usage becomes optimal. "Usage is positive only when the skill-neutral effect α\alpha exceeds an adoption threshold α0\alpha_{0}."
  • Augmentation trap: A welfare problem where AI adoption, due to misaligned incentives or myopia, leaves workers worse off than no adoption by eroding their skills. "the decision-maker's optimal policy turns steady-state loss into the augmentation trap"
  • Automation bias: The tendency to over-rely on automated systems and neglect independent judgment. "automation bias: the tendency to defer to automated aids and lose the ability to perform without them"
  • Basins of attraction: Regions of initial conditions that lead dynamics to converge to different long-run outcomes. "the optimal policy creates two basins of attraction separated by an unstable threshold SeqS_{\mathrm{eq}}."
  • Bellman equation: The fundamental recursive equation characterizing the optimal control problem over time. "The Bellman equation for this problem is"
  • Break-even boundary: The locus in parameter space where long-run value with AI equals the no-AI benchmark. "The break-even boundary BB is the most consequential for policy."
  • Cognitive offloading: Delegating cognitive tasks to AI, reducing mental effort but potentially displacing learning. "The form captures a tradeoff in cognitive offloading."
  • Diminishing marginal returns: The property that additional AI usage yields progressively smaller productivity gains. "The parameter γ>0\gamma > 0 enforces diminishing marginal returns, because the easiest tasks are delegated first."
  • Discount rate: The weight placed on present versus future outcomes in evaluating policies. "where δ>0\delta>0 is the decision-maker's discount rate."
  • Discount-rate divergence: A mismatch between decision-makers’ and workers’ discount rates that induces overuse of AI. "Under discount-rate divergence (δF>δW\delta_F > \delta_W), the manager's policy raises usage at every skill level."
  • Dynamic program: An optimization framework over time that jointly considers current payoffs and future value. "Productivity and the Dynamic Program"
  • Exogenous: Determined outside the model rather than chosen within it. "Ganuthula treats AI as a uniform shock and takes usage as exogenous."
  • First-order condition: The necessary condition characterizing the optimal policy in continuous decision problems. "For interior policies $0
  • Human in the loop: A deployment design where human judgment remains central to shaping AI outputs. "A high-β\beta deployment is akin to keeping a human in the loop, where the worker's judgment shapes the quality of AI output so that skill remains productive."
  • Interior policy: An optimal choice that lies strictly within the feasible range (neither zero nor full usage). "Suppose an interior policy is optimal."
  • Intuition rust: Gradual degradation of expert judgment from sustained AI reliance. "which the authors term ``intuition rust''"
  • Law of motion: The equation describing how skill evolves over time given usage. "Collecting terms, the law of motion simplifies to"
  • Learning-forgetting formulation: A model structure where capability increases with practice and decays with offloading. "Following a standard learning-forgetting formulation"
  • Marginal continuation value: The incremental value of increasing current skill due to its effect on future outcomes. "where VS(S;δ)V_S(S;\delta) is the marginal continuation value of skill."
  • Moral hazard: A distortion where decision-makers optimize their objective while imposing hidden costs (skill loss) on others. "The augmentation trap is the moral hazard problem when there is incentive misalignment"
  • Ordinary differential equation: A continuous-time equation governing how variables change over time. "we get a linear ordinary differential equation."
  • Present discounted value: The sum of future payoffs weighted by a discount factor to reflect time preferences. "We measure welfare as the present discounted value of the worker's flow payoff"
  • Shadow cost: The implicit future-value penalty of current decisions, captured by the derivative of the value function. "against the shadow cost of future skill loss, V′(St)V'(S_{t})."
  • Skill complementarity: A regime where AI becomes more productive when paired with higher human skill. "Skill Complementarity: Usage Increasing in Skill"
  • Skill externality: A benefit of worker capability not fully captured by the firm’s objective. "Worker Skill Externality"
  • Skill stratification: Persistent divergence in skill levels across workers due to self-reinforcing usage dynamics. "Persistent skill stratification under β<1\beta<1 with (1−β+2κaSˉ)Sˉ>2γ(1-\beta+2\kappa a\bar S)\bar S > 2\gamma."
  • Steady state: A long-run equilibrium level of skill (and usage) where dynamics cease to change. "Skill converges to a steady state S^<Sˉ\hat S<\bar S whenever u∗>0u^*>0."
  • Steady-state loss: A case where the long-run outcome with AI is worse than the no-AI baseline despite short-run gains. "producing steady-state loss: the worker ends up less productive than before adoption."
  • Unstable interior equilibrium: An interior fixed point such that small deviations lead away from it. "Let Seq:=Sˉ(1−u0)/(1+u1Sˉ)S_{\mathrm{eq}} := \bar S(1-u_0)/(1+u_1\bar S) denote the unstable interior equilibrium."
  • Value function: The total discounted payoff as a function of current skill, used to evaluate optimal policies. "the value function V(S)=aS2+bS+cV(S)=aS^2+bS+c is quadratic"
