This paper explores the impact of executive compensation structure on firm debt choices. To analyze the relationship between executive compensation and firm debt structure via the managerial effort channel, we extend the theoretical model developed by Boot et al. (1991) by incorporating an agent-principal model. We employ data from US Equity Real Estate Investment Trusts (REITs) to empirically assess the model's implications. The evidence presented in this study reveals that when executive compensation exhibits a higher sensitivity to the firm's stock price (represented by a higher Delta), the firm tends to use a greater proportion of secured debt within its overall debt structure. This phenomenon can be attributed to the managerial effort channel: firms with higher Delta values tend to engage in investments that are more effort-sensitive, and these investment choices are positively associated with increased utilization of secured debt, where the collateral plays the role of incentivizing the manager to put more effort into projects – an “effort-lifting” behavior. These findings hold for an expanded sample consisting of firms from all industries. Our analysis offers a fresh perspective on the use of collateral and executive compensation as a tool to mitigate principal-agent problems.

This paper examines how Chinese firms use WeChat for voluntary disclosure. Using a topic model, we classify over 1.6 million WeChat articles into two categories: “relevant” and “noise” articles. We find that on days when firms publish value-relevant articles, there is a significant increase in abnormal returns and stock liquidity. Further analyses reveal that WeChat serves as an alternative disclosure channel for providing new information. Firms also use WeChat to complement mandatory disclosure. However, we find that firms with negative earnings tend to issue more noise articles around earnings announcements. These noise articles are associated with higher short-term announcement returns in cases of significantly negative earnings events. These results suggest that firms may engage in opportunistic WeChat disclosure behavior. Collectively, our study highlights the significant role of WeChat in the voluntary disclosure practices of Chinese companies.
