It sketches the feedback-loop mechanism and previews the main results, including the informational/strategic decomposition and the role of dispersed beliefs. It then positions itself against feedback and Bayesian persuasion models. The model is built sequentially: setup, a no-CRA benchmark, equilibrium rating strategies, and real effects relative to the benchmark. Comparative statics yield empirical predictions, followed by a section on belief dispersion. The conclusion restates the contributions, extends the mechanism to other settings and suggests further research.
