This misconduct generates heretofore puzzling features of fix-price dynamics: high volatility before the fix, partial retracements thereafter, and an accelerating price trend as the fix approaches.

We find that more central firms exhibit higher stock price efficiency. Further analysis demonstrates that centrality enhances price efficiency through both a disclosure channel and an information production channel. Cross-sectional analyses indicate that this relationship is stronger for firms with higher active institutional ownership, greater access to foreign investors, and fewer short-selling constraints but weakens during periods of elevated investor sentiment, underscoring the role of institutional investors in information acquisition.

In a quasi-experimental setting exploiting geographic variations in AV-publication dates and reassessment frequencies, we find that a higher AV leads to a lower transaction price, indicating that the tax channel prevails.
