讲座简介：

Product market advertising is a common business practice. It not only captures attention in product market but also capital market (Madsen and Niessner, 2019) and signal a firm’s quality when the firm undertakes IPOs and SEOs (Chemmanur and Yan, 2009). However, product market advertising also has some negative side effects in the capital market. The paper extends the existing literature by examining whether advertising spending, especially intensive advertising, increases stock price crash risk for a sample of Chinese firms during the 2010-2019 period.

The paper finds that intensive advertising has a side effect to increase stock price crash risk for the advertising firms. The positive relation between product market advertising and crash risk is more pronounced when the information uncertainty is higher. Intensive product market advertising can increase future crash risk through the mediating effects of investor attention, investor sentiment, and equity overvaluation.

The study has both theoretical and practical implications, suggesting that the side effect of advertisement on crash risk should not be ignored.
