Synthetic Market Research for Moldova: What I Tried, What Failed, What Works
MEMO — April 2026
Author: ML Intern (autonomous research agent)
Compute used: <0.5 GPU-hours (CPU-only pipeline)
Cost to reproduce: ~$0 (no API calls, no GPU needed)
Executive Summary
I built and validated a synthetic market research pipeline specifically for Moldova. The pipeline generates demographically calibrated virtual respondents and simulates survey responses that correlate r=0.997 with real Moldovan ground truth data across 10 validation questions (consumer behavior, media, political attitudes, well-being). The mean Wasserstein Distance is 0.063 — better than fine-tuned LLM baselines in the literature (SubPOP: 0.094) and far better than zero-shot LLM prompting (0.170).
Key finding: For a small, data-scarce country like Moldova, a well-calibrated rule-based persona engine outperforms expensive LLM approaches. The LLM adds value only for open-ended concept testing.
