Dataset
Credit
Borrower-month observations from a credit panel, with synthetic regressors and outcome added for benchmarking.
Graph Summary
A comparatively well-connected real panel; useful for baseline timing.
The primary benchmark graph is built from unique (id1, id2) pairs. The figure shows a binned sparsity pattern of the bipartite incidence block, with both partitions relabeled to contiguous integer identifiers. This block is the off-diagonal part of the corresponding graph Laplacian.
Variables
Columns in the clean CSV:
The v1 graph uses id1 and id2. Additional identifier-like columns available for richer specifications: ruc, t.
Source Notes
Borrower-period credit panel collected by the author.
Identifiers are anonymized; regressors and outcome are synthetic benchmark variables.
