Probabilistic pacing under non-stationary platform conditions
Peer-reviewedK. Novak, E. Lambert, R. Iyer · Journal of Marketing Analytics · vol. 14 · June 2026
We formalise pacing as a constrained stochastic control problem with non-stationary cost dynamics. The proposed estimator outperforms moving-average baselines on 11 of 12 real-world panels; mean absolute percentage error of end-of-period landing improves by 38%.

Hidden FX leakage in cross-border advertising spend
Pre-printS. Aldridge, T. Wei · ADmetric working paper · May 2026
Across 2,400 advertiser-months we measure the cost of platform-native FX conversion vs. corridor-managed alternatives. The median advertiser absorbs 113 basis points of avoidable cost; the 90th percentile absorbs 207 bps. We present a decision rule for when corridor management pays for itself.

Reconciliation accuracy as a leading indicator of forecast quality
Peer-reviewedP. Halpern, M. Demir · Quantitative Finance Letters · forthcoming · April 2026
We show that 28-day forecast MAPE is causally linked to upstream reconciliation accuracy. A one-percentage-point lift in reconciliation accuracy reduces forecast MAPE by 0.42 percentage points (95% CI 0.31–0.53). Implications for audit committees and finance controls.

Guardrails-as-code: latency, false-positive rate and operator trust
Peer-reviewedJ. Okonkwo, A. Reinhardt · ACM CHI Workshop on AI Governance · March 2026
We instrument 38 production policy engines and measure the trade-off between guardrail latency and operator override rate. Below 120 ms P95, override rate collapses by 71%; above 300 ms, operators bypass guardrails within two weeks. Design implications for any money-moving automation.

Idle cash in marketing operating accounts: a 600-firm study
Working paperL. Marin, F. Kovac, S. Aldridge · ADmetric working paper · November 2025
Sampling 612 mid-market firms we find a median 4.2 weeks of paid media spend held in zero-yield operating accounts. We model the opportunity cost at €148M aggregate per annum and propose a laddered sweep policy that preserves daily operational headroom.

Counterfactual evaluation of automated budget reallocation
Pre-printR. Iyer, E. Lambert · Marketing Science · under review · September 2025
Using inverse-propensity weighting across 1.4M reallocation decisions, we estimate the incremental return of automated vs. manual reallocation. The automated policy yields +6.1% incremental ROAS (95% CI 4.8–7.4) with no measurable increase in brand-safety incidents.
