Reviews Written Without Verified Purchase: A Conceptual Backtest on Amazon Books- data preperation Python files

This archive contains the final Python scripts used in the empirical workflow of the paper “Reviews Written Without Verified Purchase: A Conceptual Backtest on Amazon Books.” The files in this archive were used to process the raw Amazon Books review and metadata files, build the review-level analytical dataset, estimate the main comparison models, and generate the final tables and figures reported in the manuscript.

The archive includes the final versions of the following scripts:
- 01_filter_books_2023.py
- 02_prepare_review_level_analysis.py
- 03_run_replication_models.py
- 04_make_tables_figures.py
- README_pipeline.txt

These scripts represent the final working pipeline used in the study.
