ANCHOR Impact: Simulation-Based Policy Recommendations
Prepared for New Jersey Division of Taxation & Wealth Disparity Task Force
Executive Summary
Agent-based simulation of 1,000+ NJ households reveals that behavioral barriers — not eligibility rules — are the primary driver of inequitable ANCHOR outcomes. Lower-income eligible households participate at 49% vs 76% for higher-income eligible households, undercutting the program's progressive design. Three modifications can improve vertical equity by 40–50% with neutral or reduced fiscal impact.
| State Objective (FY2026) | ANCHOR Current Design | Proposed Modifications |
|---|---|---|
| Maximize affordability | 61% participation → $1.92B delivered | 73–100% participation → $2.14–2.38B |
| Ensure vertical equity | VE Score: 1.69 (moderate) | VE Score: 2.15–2.61 (strong) |
| Evidence-based allocation | Limited behavioral data | Simulation-informed targeting |
| Cost efficiency | $2,740 per participant | $2,440 per participant (tiered) |
Key Findings
1. Participation Gap Is Behavioral, Not Structural
The 27-percentage-point gap between Q5 (76%) and Q1 (49%) participation contradicts rational expectations — lower-income households gain more from ANCHOR ($2,000 = 3–4% of income) yet apply less. Primary barriers identified through agent reasoning analysis:
- Complexity aversion (34%): Application process perceived as burdensome
- Institutional distrust (28%): Skepticism about government follow-through
- Procrastination (19%): Present bias — immediate effort vs. delayed reward
- Information gaps (11%): Unaware of eligibility or program details
2. Fund Usage Varies by Income
Lower-income recipients allocate 68% to immediate consumption vs. 41% for higher-income recipients, who save 26%. This confirms differential liquidity constraints and suggests ANCHOR funds have higher marginal utility for lower-income households.
3. Stress Reduction Is Progressive When Delivered
Q1 recipients experience 22-point stress reduction vs. 8 points for Q5 — the program works well for those who receive it. The challenge is delivery, not design.
Recommendations
Pre-Populated Applications
Highest Impact / FeasibilityAction: Use existing tax return data to auto-fill ANCHOR applications; residents verify and submit.
Evidence: Reduces application time from 30 to <5 minutes. Simulation projects +22 pp low-income participation increase.
Timeline: 12–18 months for IT integration. Cost: ~$2–3M one-time, neutral ongoing.
Tiered Benefits by Tax Burden Ratio
Highest Equity ImprovementAction: Replace flat $1,500/$2,000 with burden-scaled formula:
- Tax/Income > 10%: $2,500
- Tax/Income > 8%: $2,000
- Tax/Income > 6%: $1,500
- Tax/Income ≤ 6%: $1,000
Evidence: Improves VE score 43%, reduces total cost 7%. Timeline: 6 months.
Targeted Community Outreach Pilots
Addresses Geographic DisparitiesAction: Deploy community liaisons in 5 lowest-participation counties (Cumberland, Salem, Atlantic, Cape May, Gloucester) for in-person application assistance.
Evidence: Social proof effects project 30–40% participation increase in targeted areas.
Timeline: 3–6 month pilot. Cost: ~$250K annually (~0.01% of ANCHOR budget).
Implementation Timeline
Methodology Note
Results generated via agent-based simulation with 1,000 heterogeneous household agents distributed across New Jersey's 21 counties. Agent incomes sampled from log-normal distributions calibrated to Census ACS 2024 county-level data. Behavioral parameters (financial literacy, trust, risk aversion) calibrated to Survey of Consumer Finances and Pew Research data. Application decisions modeled using behavioral probability functions incorporating complexity aversion, present bias, and social proof effects. Five policy scenarios compared with fixed random seeds for reproducibility.
