Endogenous Evidence Acquisition
Exact synthetic common-versus-independent evidence source-choice grid.
Completed finite studyChecked independently
The question
When two agents can buy independent evidence or use a free common source, can private source incentives retain common-source use when one independent channel raises net group discovery?
What we found
- DD-C-0051: In DD-008's registered two-agent source-choice fixture, common/common is a source-choice equilibrium while one-independent-source profiles are planner-optimal at five of fifteen exact grid cells; for example at p=2/3 and c=1/8.
