We develop a signaling game model of investment to explore the effects of ambiguity aversion on corporate equilibrium strategies, investment dynamics, and financing decisions in incomplete markets with asymmetric information. Our analysis shows that volatility ambiguity aversion has a similar but more pronounced effect than asymmetric information, leading to higher financing costs, lower investment probabilities, and a greater likelihood of non-participation in investment. Importantly, volatility ambiguity aversion exhibits an amplifier effect, magnifying financing costs, adverse selection costs, and distortion in investment choices under asymmetric information. This increased ambiguity aversion raises the chances of inefficient separating and pooling equilibria, resulting in notable welfare losses. These findings highlight the significant impact of ambiguity aversion on strategic decision-making and equilibrium outcomes in investment, particularly in settings marked by information asymmetry and incomplete markets.

In China, inadequate levels of cross-regional investment represent a challenge. Our study uses the bailout reform initiated in China in 2014 to test whether market-oriented reforms of this type can help stimulate national economic integration. We observed that following a bond default event, nonlocal listed firms tend to establish a higher proportion of subsidiaries in the province where the default occurred. This phenomenon can be attributed to China’s bailout reform signaling a reduction in local protectionism in financial and product markets. Meanwhile, we found that the effects of bond defaults on cross-regional investment are more pronounced under the following conditions: when the impact of the bond default is greater; when the economic and fiscal conditions of the province where default occurs are better; when local protectionism in the home province is higher; and when the degree of asset specificity of the listed firms is lower. Finally, we found that China’s bailout reform has led to positive economic consequences, including reduced operational risks and improved total factor productivity (TFP) of firms. Overall, our paper supplements the literature on bond defaults and cross-regional investment.

Using a comprehensive dataset for Chinese listed companies from 2009 to 2021, we find that online media is negatively associated with cash dividend level, and the proportion of positive news has a negative moderating effect on this relationship. Our results support the "information intermediary" effect and exclude the "external governance" and "market pressure" effects. We further propose that online media weakens the positive relationship between cash dividends and past earnings (rather than the future), indicating that cash dividends contain signals of improvement in past earnings and are replaced by online news. We also find that only firms with more positive news pay dividends that have signaling effects, and there is a synergistic effect between positive news and dividend signal. Additional results show that the effect of online media on dividend policy is more pronounced than traditional media, which has almost no influence. Our main conclusions remain valid after addressing potential endogeneity issues and conducting various robustness tests.

We examine communication of political connections in corporate China, and show that politically inclined positive words—words in connotation of political sentiment—serve as a distinct and effective signaling device for corporate political connections. Using a large sample of corporate news, we find that news’ political sentiment, instead of orthodox political measures such as occurrences of political nouns and political entities, reflects executives’ political connections for private enterprises, and is related to rent-seeking benefits in government subsidy, tax refund, financing constraints and political risk. Our results demonstrate that political sentiment is an effective way to decode subtle corporate political connections in modern China’s “Mind Politics” environment that infiltrates into private corporations.

Using sample of Chinese listed firms from Q1 2017 to Q4 2022, this article examines the impact of economic policy uncertainty on share repurchases. We find that economic policy uncertainty significantly increases the probability and scale of open market share repurchases. Private enterprises, government-supported enterprises, innovative enterprises, and investment hotspot enterprises repurchased more shares during periods of high economic policy uncertainty. Additionally, the market value of repurchase programs issued during periods of high economic policy uncertainty is larger. We also discover that economic policy uncertainty substantially influences the characteristics, timing, and outcomes of the repurchase programs. Lastly, this article confirms that share repurchase behavior has a similar effect to voluntary disclosures and can alleviate the information asymmetry triggered by economic policy uncertainty. In summary, Chinese listed firms have resorted to more share repurchases during periods of high economic policy uncertainty to convey their actual value and boost investor confidence, aligning with the signaling motive. Open market share repurchases surface as an efficacious instrument to cope with the risk from economic policy uncertainty.

We uncover a signiffcant relationship between the persistence of marketing and investment skills among U.S. mutual fund companies. Using regulatory filings, we calculate the share of marketing-oriented employees to total employment and reveal alarge heterogeneity in its level and persistence. A framework based on costly signaling and learning helps explain the observed marketing decision. The model features a separating equilibrium in which fund companies’ optimal marketing employment share responds to their past performance differently, conditional on the skill level. We confirm the model prediction that the volatility of the marketing employment share negatively predicts the fund companies’ long-term performance.

In China's labor market, there is a phenomenon that enterprises choose whether to provide "social insurance and housing fund" to laborers autonomously. This paper use micro-data from two leading Internet recruitment platforms and empirically finds that in a labor market with double-side information asymmetry, "social insurance and housing fund" is not only a cost but also a signal. Providing workers with "social insurance and housing fund" can both send a signal of stable operation to the labor market and identify high-quality workers for enterprises. With an instrument variable of local average social security payment rate, this paper excludes the endogenous effect of labor supply on wages while the signaling effect above is still significant. In addition, "housing fund" has a stronger signaling effect than "social insurance", and the strength of the two signaling effects is affected by the scale of the enterprises and the level of local payment rates. This paper also introduces a theoretical framework of two micro-mechanisms — signaling and screening — into the analysis. In terms of policies, this paper proposes to strengthen the information disclosure and the propagation of social security payment, and further reduce the financial burden of enterprises.

We propose a behavioral signaling framework to explain the positive announcement effects of stock splits. (Retail) investors view stock splits as good news and are loss averse. Thus, a stock split can boost investors’ expectations of the firm’s growth potential and its stock price, but may also cause disproportionally larger price declines if the firm cannot meet investors’ high expectations. In equilibrium, only managers with favorable information use stock splits to signal. Empirical analyses of stock splits in China find supporting evidence for this explanation: (1) investors become more optimistic after stock splits; (2) higher split ratios are associated with stronger market reactions; (3) splitting firms have better future performance than non-splitting firms; and (4) they experience larger price declines when falling short of investors’ expectations. These findings, along with the unique institutional features of the Chinese market, help differentiate our behavioral explanation from alternative explanations within the rational framework.
