The study introduces 'earnings purity,' a concept based on the 'gold content' of target earnings, to evaluate its impact on merger and acquisition (M&A) premiums. Our findings reveal that targets with higher earnings purity command increased valuations and premiums. Further analysis of the information effects uncovers a U-shaped relationship between earnings purity and negotiation duration, suggesting that elevated premiums might not always be justified. The heterogeneity test indicates that the effect of a target firm's earnings purity on M&A premiums is more pronounced in cross-border and inter-industry M&As. However, it is less influential in cases with larger target firms and better external conditions. These results highlight the dual aspects of M&As, presenting them as both advantageous and potentially hazardous.

We study the effect of managerial career concerns on informational feedback from stockmarkets. We set up a model in which managers with career concerns can learn information from their own information production or from stock price feedback. A key insight from the model is that if managerial career concerns are high, a less frictional market induces more information production by both managers and speculators. As a result, although price informativeness improves, managers learn less from the stock market, contrasting with the classical view in the literature on stock price feedback. Exploiting a quasi-natural experiment, we document evidence consistent with model predictions.

We examine the effects of controlling shareholder stock pledge on corporate acquisition decisions and associated performance. Consistent with our aggravated expropriation hypothesis, we find that pledging firms in China initiate more takeovers, but these acquisitions conducted by pledging firms experience lower announcement returns. We adopt the difference in differences and the instrumental variable approaches to establish causality. Channel tests further reveal that pledging acquirers overpay for the deals and are more likely to be involved in related party transactions. Cross-sectionally, we find that the relations between the share pledge and corporate acquisitiveness and returns are more pronounced for non-SOEs and firms with high-level excess cash. Lastly, we document that pledging acquirers underperform in the long-run in terms of lower ROAs and a greater likelihood of goodwill impairment. Overall, our findings indicate that controlling shareholders increasingly expropriate minority shareholders through self-serving corporate takeovers after the stock pledge.
