Workforce Arbitrage

The measurable cost delta between a human workforce and an equivalent agentic stack performing the same revenue-generating tasks.

Workforce arbitrage is the quantifiable expression of operational arbitrage at the role and task level. Arco calculates it as the fully-loaded cost per unit of output for a human operator versus the equivalent agentic stack — including LLM inference, infrastructure, tooling, and stewardship overhead.

At Tier 1 tasks, the arbitrage is extreme: a single agentic workflow running at scale can produce the equivalent of 37–50 human operators' output at a fraction of the cost. At Tier 3 tasks, the arbitrage collapses — human judgement remains essential and cheaper when the task frequency is low.

The stewardship model's advantage over pure agentic deployment is credibility and resilience, not cost. The Arco Stewardship Model lands between pure agentic and pure human — economically superior to human teams while operationally more reliable than unmanned agentic deployment.
