Replication Report: Concentration Bias in Intertemporal Choice

Note: Results were obtained via Stata-to-Python translation. Numerical differences may be translation artifacts rather than genuine reproducibility failures. Running with native Stata would provide a more accurate assessment.

Overall: Fully Reproducible

2 coefficients reproduced within tolerance across 2 tables. Match scores of 90% indicate excellent agreement with differences under 4%.

Summary

The paper investigates concentration bias in intertemporal choice through laboratory and online experiments examining how participants allocate effort across time periods. Both replicated coefficients show excellent agreement: Table 2 Coeff 7 (paper: 0.259, code: 0.2492, 3.8% relative difference) and Appendix Table D.1 Coeff 4 (paper: 0.081, code: 0.0838, 3.5% relative difference). These differences fall well within acceptable tolerances for cross-software replication.
