Auditing and Fixing Economic Validity in Tabular Foundation Models for Discrete Choice

arXiv:2605.26559v1 Announce Type: new Abstract: Tabular foundation models achieve strong accuracy on choice prediction tasks, but their predictions often violate the economic logic those tasks require: raising a price sometimes increases predicted demand, and implied willingness-to-pay estimates are frequently negative or implausible. We propose a two-stage adapter that embeds foundation model predictions within a utility-maximization framework. In the first stage, we estimate a standard choice model whose parameters are constrained to obey economic theory. In the second stage, we freeze those

Why this matters
Why now

The proliferation of foundation models into diverse application areas, including economic decision-making, necessitates a critical examination of their real-world applicability and adherence to established principles.

Why it’s important

Ensuring economic validity in AI models is crucial for their adoption in high-stakes financial and policy applications, preventing erroneous insights and fostering trust in AI-driven decision systems.

What changes

The ability to audit and correct economic inconsistencies in AI models means that foundation models can be deployed more reliably in fields requiring adherence to economic principles, expanding their utility and impact.

Second-order effects
Direct

Increased real-world deployment of economically validated AI models in critical business functions.

Second

Greater demand for AI systems that can demonstrate adherence to domain-specific theoretical frameworks, beyond mere predictive accuracy.

Third

The emergence of new regulatory and auditing standards specifically for the economic and ethical grounding of AI models in regulated industries.
