Pilot Early, Commit Late: A Real-Options Model of Enterprise AI Adoption under Rapid Technological Progress
cs.AI
Quick verdict
清晰的两期实期权论文论证了试点、等待和部署是截然不同的；其数学推导正确但较为初级，且明确以说明性案例为主。
Summary
本文通过一个两阶段、风险中性的模型，对时间选择问题进行了形式化，在该模型中，企业可以立即部署（沉没成本 I、干中学 d、捕获分数 rho）、运行试点（成本 p、能力提升 ℓ）或进行等待。第4节的主要结果包括：均值保留下不确定性的增加通过凸性提高了等待和试点的价值，而立即部署的价值仅取决于边界均值——因此不确定性并不总是延缓采用；在捕获分数 rho 较低时，更快的边界进展在理性上可能有利于推迟完全部署（即“AI 等待悖论”）；试点仅在成本低于创建能力的期望价值时优于等待；对于足够大的 ℓ，存在一个非空的试点阶段采用区域；并推导出了闭式解的模块化阈值。连续时间扩展恢复了这样的结果：不确定性会提高采用门槛，而能力和模块化则会降低采用门槛。局限性：结果取决于线性盈余规范；假设边界从不降至当前水平以下，从而使期权免受不利进展的影响；学习是确定性的，没有信号价值；不存在竞争和融资约束；所有数值实验都是说明性的，且未发布代码。

Key claims under review
- A mean-preserving increase in frontier uncertainty raises the value of waiting and piloting but leaves immediate deployment's value unchanged when its payoff is affine in the frontier (Proposition 1).
- Faster expected frontier progress reduces the relative attractiveness of immediate deployment whenever k0·P(A·k0·M > I) exceeds ρ(k0+d) — the 'AI waiting paradox' (Proposition 2, Eq. 12).
- A pilot dominates pure waiting if and only if its cost p is at most δ·E[Δ(M;ℓ)], the expected capability value it creates (Proposition 3).
- Sufficiently valuable organization-specific learning creates a nonempty region in which piloting strictly dominates both deploying and waiting (Proposition 4), and a closed-form modularity threshold ρ* (Eq. 21) separates deployment from the best outside option (Proposition 5).
Strengths
Clean three-way action separation
Section 3 makes deploy, pilot, and wait economically distinct objects: rho (Eq. 2) operationalizes architectural obsolescence as capture of frontier improvement, while the pilot's payoff is capability, not diluted operating cash flow — an explicit contrast with miniature-rollout thinking (Sec. 3.1).
Quantified, decision-relevant comparative statics
Proposition 2 (Eqs. 9–13) yields an exact comparison: faster frontier progress raises waiting over deployment whenever k0·P(A·k0·M > I) > ρ(k0+d), turning the 'AI waiting paradox' from a slogan into a checkable inequality with a fully detailed dominated-convergence proof in Appendix A.

Frequently asked questions
What is the 'AI waiting paradox' in this paper?
The finding that faster expected AI progress can make AI more valuable overall while rationally reducing a firm's incentive to fully deploy today. Because an installed architecture captures only a fraction ρ of future frontier improvement, quicker progress raises the value of the later deployment option faster than it raises the value of deploying immediately. Formally, waiting beats deploying when k0·P(A·k0·M > I) > ρ(k0+d).
When should a company pilot instead of just waiting to adopt AI?
According to the paper's Proposition 3, a pilot strictly beats pure waiting exactly when its cost p is no more than the discounted expected value of the capability it builds, δ·E[Δ(M;ℓ)]. High uncertainty alone never justifies a pilot — what matters is whether the pilot creates transferable capability (workflow knowledge, evaluation infrastructure, portable integration) that survives model changes; a polished demo with no transferable learning has ℓ ≈ 0.
Is the math in this paper correct?
The proofs in Appendix A are elementary and check out: Proposition 1 follows from convex ordering of [AkM − I]+, Propositions 2, 3, and 6 from dominated convergence with indicator thresholds, and Proposition 5 from solving a linear equation for the modularity threshold. The continuous-time corollary reproduces the standard Dixit–Pindyck result. The results are correct but deliberately simple; their value lies in the framing, not analytical depth.
Can I use the paper's numerical parameters to calibrate my own AI investment decision?
No. The baseline values (A=1, k0=0.8, I=2, δ=0.95, m0=1, d=0.2, ℓ=0.4, p=0.12) are explicitly illustrative normalizations chosen to display distinct policy regions, not estimates of enterprise returns or costs. The paper's own Section 5 and disclosure state they should not be interpreted as empirical calibration or investment advice.
About this review
This is an AI-generated preliminary review by Evolve.Pub, produced from the openly available text of the paper. It is not peer review and does not represent the authors' views. The canonical record of the paper is at the publisher link above.
- Figures 1–6 are not analyzable from the text extraction; assessment of figures rests on captions, Table 3 point values, and stated formulas.
- The abstract and Section 4.5 are truncated mid-sentence in the extraction; the six results are fully restated in Section 1 and the conclusion, so coverage of the claims is complete.
- Table 1 (positioning relative to adjacent research) and Table 2 (notation) appear as captions only; the novelty assessment relies on the paper's own prose positioning.
