  • 详情 Value Investment and Gambling: An Integrated Asset Pricing Model Based on Q and Salience Theory
    We interpret industry discount rates as proxies for value investment, grounded in Q theory, while capturing gambling preferences through salience theory. Integrating these perspectives, we propose a novel asset pricing model (ST-ICAPM) that unifies value investment and salience factors, evaluating its pricing efficacy across Chinese industries from 2004 to 2023. Empirical results show that investment factors tend to negatively predict future returns, while growth factors command risk premia. However, profitability factors exhibit limited explanatory power. Investor expectations are primarily driven by profit growth, emphasizing the need to enhance profit stability for a value-oriented market. Salience intensity, especially when measured via eigenvector centrality within industry networks, serves as a strong negative predictor of returns, emphasizing the importance of conceptual connections over purely economic linkages in shaping investor behavior. Robust tests confirm that the ST-ICAPM outperforms benchmark models (FF3, CARHART4, FF5, ICAPM, and STCAPM) in terms of pricing power. Our findings emphasize the need to promote value investing and restrain gambling behavior as essential strategies to cultivate a resilient capital market in China.
  • 详情 Does Investor Misvaluation Drive the Takeover Market?
    This paper documents the relations between firms' pre-offer market valuations and takeover behavior, and evaluates their consistency with the Q theory and the misvaluation theory of takeovers. We employ two valuation measures: price/book ratios and ratios of price to residual income model value. Market valuations of bidders and targets influence the means of payment chosen, the mode of acquisition, the premia paid, target hostility to the offer, the likelihood of offer success, and bidder and target announcement period stock returns. The evidence is broadly consistent with both hypotheses. The evidence for the Q hypothesis is stronger in the pre-1990 period than in the 1990-2000 period, whereas the evidence for the misvaluation hypothesis is stronger in the 1990-2000 period than in the pre-1990 period.
