股利政策的股东财富效应:来自中国股市的经验证据

Based on the special separated equity management structure of the listed companies in China and using a sample of the listed companies with distributed dividend in 2003 and 2004, this paper tests the shareholder wealth effects of dividend policy in Chinese separated equity market. Results show that shareholders of non-circulating stock get a high return rate by cash dividends, and circulating shareholders obtain a high short-term return rate by stock dividends.

中国资本市场融资顺序新证:可转债发行公告效应研究

This paper empirically shows that the announcements of the issue of convertible bonds (CBs) by Chinese firms have significant negative effects on shareholders’ wealth. We find that when the samples are partitioned by equity component negative market responses towards the announcements of issuing equity-like CBs are more than that of debt-like CBs. This finding is different from the “pecking order hypothesis” of Myers and Majluf (1984). By analyzing the firm characteristics of convertible bond issuers, we find that the wealth effects are negatively related to equity component, firm size and issue size of convertible bonds, and are positively related to financial leverage, liquidity structure of equity, book value of non-liquidity equity and market-to-book ratio. The underlying reason of equity finance taking precedence of bond finance in Chinese capital market can be attributed the to special “two-system-ownership structure” and corporate governance of Chinese listed companies.

What do we know about individual equity options?

This paper examines the empirical literature on individual equity options, discussing results in areas of consensus, showing findings in areas of disagreement and providing a guide for future research (especially highlighting analyses that cannot be performed with index options). Key topics include the impact of equity option listings on the underlying stock market, option market efficiency, anomalies in equity option returns, option market microstructure, investors’ behavioral biases, option price discovery, and private information revealed in equity option markets. Some directions for future research include the determinants of equity option returns and the effect of algorithmic trading in option markets.     

Corporate Social Responsibility: Is it Rewarded by the Corporate Bond Market? A Critical Note

The question of whether corporate social responsibility (CSR) has a positive impact on firm value has been almost exclusively analysed from the perspective of the stock market. We have therefore investigated the relationship between the valuation of Euro corporate bonds and the standards of CSR of mainly European companies for the first time in this article. Generally, the debt market exhibits a considerable weight for corporate finance, for which reason creditors should basically play a significant role in the transmission of CSR into the valuation of financial instruments. Given that socially responsible firms are often regarded as economically more successful and less risky, they should have lower risk premia. The results of the empirical analysis, however, reveal that based on an extensive data panel the risk premium for socially responsible firms – according to the classification by SAM Group – was ceterius paribus higher than for non-socially responsible companies. However, only one case of the models investigated was weakly significant. Thus, largely the relationship has to be classified as marginal; so CSR has apparently not yet been incorporated into the pricing of corporate bonds.     

A smiling bear in the equity options market and the cross-section of stock returns

We propose a measure for the convexity of an option-implied volatility curve, IV convexity, as a forward-looking measure of risk-neutral tail-risk contribution to the perceived variance of underlying equity returns. Using equity options data for individual US-listed stocks during 2000–2013, we find that the average realized return differential between the lowest and highest IV convexity quintile portfolios exceeds 1% per month, which is both economically and statistically significant on a risk-adjusted basis. Our empirical findings indicate the contribution of informed options trading to price discovery in terms of the realization of tail-risk aversion in the stock market.     

The Relevance of XBRL Voluntary Disclosure for Stock Market Valuation: The Role of Corporate Governance

The aim of this paper is to investigate the relevance for stock market pricing of accounting earnings of voluntary disclosures in XBRL files considering the quality of corporate governance. Results are the following. It appears that XBRL extensions attract financial analysts. Good governance is positively associated with voluntary XBRL extensions. We observe that XBRL extensions enhance the positive relationship between accounting earnings and stock price. However, this positive association is reduced for firms with good governance, suggesting a substitution effect between XBRL extensions and corporate governance. Finally, it appears that XBRL extensions would strategically be related to earnings quality. This research highlights the importance to consider governance when assessing the value relevance of XBRL disclosures for stock market pricing.     

Security Markets versus Bank Finance: Legal Enforcement and Investors' Protection

When minority investors’ rights are poorly protected, the ability of firms to raise equity capital is impaired, leading to less finance for new ventures. Fewer firms will be financed with outside equity, resulting in a low market capitalization relative to GNP. External funding requires easily enforceable claims such as debt or requires long‐term relationships with institutions. Provision of funding shifts from risk capital to debt, and to a predominance of intermediated over market finance. We report supporting evidence for a few countries. To measure investor protection, we use a price measure, the premium on voting stock, related to the control premium. In countries where the voting premium is large, corporate financing is dominated by bank lending and equity markets are much smaller.     

Seasoned equity offerings by small and medium-sized enterprises

Most analyses of small firms’ decision to seek outside equity financing and the conditions thereof concern private firms. Knowledge of the risk and return of entrepreneurial ventures for outside investors is consequently limited. This paper attempts to fill this gap by examining the Canadian context, where small and medium-sized enterprises (SMEs) are allowed to list on a stock market. We analyze seasoned equity offerings launched by SMEs over the last decade. These public issuers can be considered low quality firms with poor operating performance. Managers issue equity before a large decrease in operating and stock market performance. Individual investors do not price the stocks correctly around the issue and incur significant negative returns in the years following the issue. This is particularly true for constrained issuers. We confirm that entrepreneurial outside equity attracts lemons and that individual investors cannot invest wisely in emerging ventures. Probably as a consequence of individual investors’ lack of skill and rationality, the cost of outside equity financing of Canadian public SMEs is abnormally low.     

An integrated retailer image and brand equity framework: Re-examining,extending, and restructuring retailer brand equity

Retailers are amongst the world's strongest brands, but little is known about retailer brand equity. In spite of their extensive use, we argue that current operational models are too abstract for understanding the uniqueness of the retail industry and too simplistic to understand the interrelationships among the dimensions in the retailer brand equity building process. This study contributes to the existing and largely generic retailer equity frameworks in three ways: first, by incorporating retail specific dimensions from the retailer image literature; second, by re-examining and developing the structures and relationships between the dimensions of retailer equity by testing alternative structures commonly used in the more general brand equity literature; and finally by creating a short and parsimonious scale for assessing retailer brandequity in different contexts. Three alternative models are compared and tested on six brands in both convenience and shopping goods categories, ranging from discount to middle range price levels. The outcome is an operational framework supporting the main building blocks of the conceptual brand resonance model presented in Keller (2001) with seven dimensions structured in a four-step sequence as awareness → pricing policy, customer service, product quality, physical store → retailer trust → retailer loyalty, thereby describing retailer brand equity as a four-step process. The extended, although parsimonious, 17-item retailer equity scale can be used by academics as well as practitioners to examine the underlying values of retailer brands and has the potential to incorporate additional dimensions and attributes to investigate specific retail contexts without creating lengthy questionnaires.     

A UNIFIED FRAMEWORK FOR PRICING CREDIT AND EQUITY DERIVATIVES

We propose a model which can be jointly calibrated to the corporate bond term structure and equity option volatility surface of the same company. Our purpose is to obtain explicit bond and equity option pricing formulas that can be calibrated to find a risk neutral model that matches a set of observed market prices. This risk neutral model can then be used to price more exotic, illiquid, or over‐the‐counter derivatives. We observe that our model matches the equity option implied volatility surface well since we properly account for the default risk in the implied volatility surface. We demonstrate the importance of accounting for the default risk and stochastic interest rate in equity option pricing by comparing our results to Fouque et al., which only accounts for stochastic volatility.
