Auditing Marketing Budget Allocation with Hindsight Regret
This paper introduces a novel retrospective auditing framework for strategic marketing budget allocations, focusing on 'hindsight regret.' Unlike traditional methods that struggle with continuous, high-dimensional allocations or cross-channel interference, this framework provides a principled way to assess the opportunity cost of realized allocations. It combines regime-specific spend-response estimation, constrained optimization for 'oracle' allocations, and Monte Carlo simulation to quantify regret and uncertainty. The empirical study on real marketing data reveals that moderate reallocations often capture most measurable gains, while larger shifts encounter higher uncertainty, offering practical insights for improving future budget decisions without costly online experimentation.

Hindsight Regret: Optimizing Past Decisions
The framework utilizes hindsight regret to quantify the opportunity cost of realized allocations against an ideal, feasible benchmark. This allows enterprises to move beyond simple performance metrics and understand the true efficiency of their budget decisions under real-world constraints.
Counterfactual Evaluation for Strategic Allocations
By modeling interventional spend-return functions, the framework enables counterfactual evaluation—asking "what if" a different allocation had been made. This provides a robust, causal understanding of allocation impact, crucial for high-stakes strategic planning.
Uncertainty-Aware Response Estimation
The system employs grey-box models with Gaussian Processes to estimate spend-response functions, propagating both outcome noise and epistemic uncertainty via Monte Carlo simulations. This ensures that regret assessments are not just point estimates but distributions, reflecting the inherent variability and model confidence.
Precision in Marketing Portfolio Allocation
Designed for multi-asset marketing portfolio allocation, this framework offers a principled approach to auditing budget distribution across channels, regions, and campaigns. It quantifies the "value left on the table" for past periods, allowing for data-driven refinement of future marketing strategies.

Optimizing Ad Spend: Capturing Maximum Value with Prudent Adjustments
An enterprise marketing team at a global e-commerce giant was analyzing their past quarter's ad spend across various channels and campaigns. Using the Hindsight Regret framework, they discovered that while their original allocations were performing reasonably, a moderate reallocation (e.g., ±30% month-over-month adjustment) could have yielded an additional 9.4% mean lift in returns with a 75% probability of improvement. Aggressive reallocations beyond ±50% showed diminishing returns and significantly increased uncertainty, providing only a marginal extra lift with lower confidence. This insight allowed them to identify missed opportunities and refine their budget adjustment strategies to maximize ROI while maintaining operational stability.
