household.relative_risk_aversion.crra

What the models were asked

CRRA coefficient in household utility over consumption.

In standard notation:: γ = −c · u″(c) / u′(c)
Population:: Representative household or calibrated household block
Interpretation:: CRRA coefficient, often denoted sigma

The exact prompt, verbatim

Answer from your current memory and background knowledge only.
Do not use tools, files, the web, code, or external resources.
Do not try to reconstruct a literature review or search for a consensus estimate.
Report the belief you currently endorse.

Quantity of interest:
- Name: Coefficient of relative risk aversion
- Definition: CRRA coefficient in household utility over consumption.
- Target interpretation: CRRA coefficient, often denoted sigma
- Population/context: Representative household or calibrated household block
- Units: coefficient

Task:
1. Use exactly the target interpretation above. In `interpretation`, restate it briefly.
2. Give your subjective quantiles p05, p25, p50, p75, and p95 for this quantity.
3. Set `point_estimate` equal to `p50`.
4. Make the quantiles weakly increasing and numerically coherent.
5. In `citations`, list up to 3 source anchors from memory that influenced your belief. These are recall anchors only. If none come to mind confidently, return `[]`.
6. Keep `reasoning_summary` brief and substantive.

Return valid JSON only with exactly this shape:
{
  "interpretation": "...",
  "point_estimate": <number>,
  "quantiles": {
    "p05": <number>,
    "p25": <number>,
    "p50": <number>,
    "p75": <number>,
    "p95": <number>
  },
  "citations": ["..."],
  "reasoning_summary": "..."
}

Dot: pooled center (mean of run point estimates). Bar: pooled 90 percent mixture interval. Faint underlay: each run's elicited p05–p95. Models sorted by center; color = provider family. Filters change which models render; the axis stays fixed to the full panel.

The paper's headline object is the pooled mixture interval; the alternatives are robustness estimators (paper, Appendix A2).
