The externalities of credit default swaps on stock return synchronicity

We examine the externality effect of customer firms’ credit default swap (CDS) trading on the stock price informativeness of supplier firms. Our empirical results show that firms with a high proportion of sales to CDS referenced customers tend to have more firm-specific embedded information in their stock prices and thus higher stock price informativeness, which is associated with a lower level of stock return synchronicity. We provide new evidence of CDS trading externality on equity market information environments along the supply chain.     

The stock market performance of exploration-oriented and exploitation-oriented cross-border mergers and acquisitions: Evidence from emerging market enterprises

This study builds on insights from mergers and acquisitions (M&A) studies and the perspective that stock market performance is affected by the M&A strategies of firms. Past studies show that acquisitions are an effective way to exploit existing knowledge and explore new possibilities. We argue that stock market performance can be a response to exploration/exploitation strategies in the context of cross-border M&As by emerging market multinationals. Based on cross-border M&A data of Chinese multinationals, we find that exploration-oriented acquisitions have worse stock market performance than exploitation-oriented acquisitions. Furthermore, we find support for our premise that acquiring firms can reduce the risk of exploration-oriented acquisitions by having more high-discretion slack resources or by maintaining a high level of equity share of the target firm. In addition, acquiring firms perform better if they conduct exploration-oriented acquisitions in related industries. Our results contribute to a better understanding of exploration and exploitation in the context of M&As.     

Information assimilation and stock return synchronicity: Evidence from an investor relations management platform

In this paper, we employ a unique information assimilation measure for listed firms in China based on their communications with investors through an online platform designated by the China Securities Regulatory Commission (CSRC). We examine whether a firm's efforts in enhancing investors’ information assimilation, such as providing more quality clarifications and explanations, helps facilitate the incorporation of firm-specific information in stock prices and reduces stock return synchronicity. We find robust evidence that more quality-clarifying communications contribute to lower stock return synchronicity after controlling for other information sources, and the decrease in synchronicity is mostly due to increased firm-specific information rather than noise. The causal relationship is established using a stacking DID approach and a PSM method. In a further analysis, we find that more quality communications can strengthen investors’ reaction to good news and smooth their reaction to bad news. Our study provides direct evidence that enhanced information assimilation benefits firms by entrenching more firm-specific information into stock prices.     

Stock market,credit market,and heterogeneous innovations

The relative importance of credit market development and stock market development in boosting innovation remains a long-standing debate issue. In this study, we document how different types of financial markets development affect heterogeneous innovations. Using a broad sample across 42 developed and emerging economies and a generalized difference-in-differences identification strategy, we find that stock market development leads to significantly higher substantive innovation, especially in young and small firms, but has negative impact on incremental innovation. Conversely, credit market development promotes incremental innovation, especially in mature and large firms, but has negative impact on substantive innovation. Further analyses indicate that stronger shareholder protection enhances the positive impact of stock market on substantive innovation, while stronger creditor rights enhance the promoting effect of credit market on incremental innovation, and even turn the negative impact of credit market on substantive innovation into positive. Our paper provides new insights into the heterogeneous effects of credit market and equity markets on the real economy.     

Investor sentiment and advertising expenditure

A strategic issue facing marketing managers is ‘how much and when’ to spend on advertising. We argue that investor sentiment in the stock market may influence advertising expenditure by affecting firms' ability to raise new funds. We show that during periods of low (high) investor sentiment, firms decrease (increase) their advertising expenditure, even though the effectiveness of advertising is greater (lower) during such periods. We also find that these results are stronger for financially constrained firms that rely more on external financing. Our findings suggest that marketing managers can improve the efficiency of their advertising expenditure by raising (reducing) it during periods of low (high) sentiment.     

Takeover protection and stock price crash risk: Evidence from state antitakeover laws

We exploit the passage of state antitakeover laws to examine the relation between takeover protection and stock price crash risk. We find that firms incorporated in states that passed the laws are negatively associated with future stock price crash risk in the post-law periods, suggesting that takeover protection mitigates bad news hoarding activities. Further analysis shows that the mitigating effect is more pronounced when firms have severe information asymmetry or face strong product market competition. Together, our findings shed new light on the impact of takeover threats on managerial incentives to engage in bad news hoarding.     

Modelling spillovers between stock market and FX market: evidence for Nigeria

Abstract

The need to capture the foreign exchange (FX) and stock markets nexus in Nigeria is underscored by the rapidly expanding financial markets integration due to trade and financial liberalization policies which seem to have enhanced the inflow of capital as well as accelerated investment/business interactions. Using variants of the VARMA-AMGARCH model of McAleer, Hoti, and Chan (2009), we find that volatility persistence in the stock market is accentuated by bad news in the market and moderated by good news in the FX market. Finally, we establish that ignoring the asymmetric effects may exaggerate the spillover results.     

Do Patented Innovations Reduce Stock Price Crash Risk?*

Using a large sample of US firms, we document a significantly negative relation between the number of patents (citations) and stock price crash risk. Our findings are consistent with the arguments that patented innovation activities send a high‐quality signal and reduces proprietary information costs, which lowers information asymmetry and enhance disclosure. Further, we find that such impact of patented innovation on stock price crash risk is more pronounced in firms with weak corporate governance and high information opacity. Our findings provide new evidence on the real effects of patented innovation on crash risk in equity market.     

Pricing and persuasive advertising in a differentiated market

This paper examines the effects of consumer preferences, firms’ costs, and advertising efficiencies on firms’ pricing and persuasive advertising strategies. We show that as the firms’ horizontal differentiation increases, the firm with a lower value-added product tends to increase persuasive advertising, whereas its competitor tends to reduce advertising. Second, the firm receiving a favorable shock in product valuation will complement the favorable change with additional persuasive advertising rather than reduce advertising spending. Third, an equal improvement in advertising efficiency in the industry will lower the profits for both firms, whereas a decrease in advertising efficiency in the industry can benefit both firms. Fourth, a larger shock that improves a firm’s product valuation or unit cost is more likely to induce higher advertising spending in the industry. Lastly, an exogenous increase in the separation between firms’ product valuations or perceived qualities may actually reduce the price dispersion in the industry.     

New product preannouncements,advertising investments,and stock returns

This study examines the synergistic effects of advertising spending and new product preannouncements (NPPAs) on stock market responses. The empirical results indicate that returns of preannouncing firms over both the short- and long-term could be improved by an increase in advertising expenditure. Additionally, the results also show that the positive impacts of earnings and revenues can be enhanced, while the negative influence of trading costs can be reduced, for preannouncing firms with higher advertising expenditures. The holding returns of institutional investors can also increase with greater spending on advertising. Therefore, marketing communication strategies that aim to reduce information asymmetry within NPPAs, coupled with greater advertising expenditures, would yield more favorable investor responses.     

Product Regulation and Stock Prices: The Case of the US Food and Drug Administration

This study focuses on the stock market effects associated with the announcements of product approvals, denials and recalls by the US Food and Drug Administration (FDA), and the impact of product approvals on research and development expenditures (R&D) and forecasts of earnings by Value Line. When the FDA announces approvals, the shareholder wealth of affected firms increases significantly. The announcements of denials and recalls by the FDA are associated with stock price declines. The stock price impact of recalls is dependent on whether the firm voluntarily withdraws a product or if the withdrawal is mandated by the FDA. Specifically, voluntary recalls are not associated with a change in stockholder wealth, while FDA mandated recalls are associated with decreases in stock price. In addition, we find that partial product recalls have a smaller impact than total recalls. An examination of the effects on competitors' stock price reveals losses when the FDA announces an approval or a recall, but no imt for a d. An analysis of changes in risk around FDA decisions suggests that, on average, betas do not change around approvals, recalls or denials. In addition, our results suggest that announcement period stock price behavior is unrelated to risk changes except for approvals where returns are positive and significant for firms with either increasing risk or no change in risk. We also find that approvals are associated with increases in R&D and forecasts of earnings for the sample firms, with returns to stockholders upon announcement of the approval being related to the increases in R&D and short-term earnings forecasts.     

Harmonious Stock Prices

Stock price movements in China still remain highly harmonious, in spite of the many significant regulatory and structural changes over the recent years. A survey of the literature reveals that harmony in the stock price movements is related to a few salient features in China＇s capital market： high ownership concentration, high incidence of the use of pyramidal ownership structure, significant state ownership, and a lack of active institutional investors. In addition, we also point out that harmonious stock prices may generally result from low intensity of private information acquisitions by risk arbitrageurs.     

Designing the content of advertising in a differentiated market

In many markets, consumers use attribute information to assess the value they expect from purchasing a product or service. This includes many low involvement experience goods including take-out food, many packaged good categories and restaurants. In these markets, quality differences exist but many differences are horizontal in nature: the consumer is interested in finding a product that meets her unique tastes. Beyond ensuring that consumers know the brand, the category and the price; it seems advertising should provide consumers with attribute information. However, a significant proportion of advertising does not provide it. In fact, within the same category, competitors respond to messages that emphasize detailed attribute information with messages that are devoid of attribute information. These messages are uninformative about product attributes. We explore how competition in a differentiated market is affected by the ability of a firm has to choose uninformative messages. We construct a model to investigate the factors that affect a firm’s decision to use advertising with detailed attribute information or advertising that does not provide it. The model demonstrates that content decisions about advertising are affected by the differences between products, the range of heterogeneity in consumer tastes and the degree to which costs increase as a function of the quantity of information in advertising. Surprisingly, even when the cost to increase the quantity of information in advertising is low, uninformative campaigns can be more profitable than campaigns with attribute information. The analysis also demonstrates that firms can be more likely to provide attribute information when there are less consumers that are attribute-sensitive. Finally, the model shows that uninformative messages can create “artificial differentiation” in some situations.     

How does stock market liberalization influence corporate innovation? Evidence from Stock Connect scheme in China

Using China's Stock Connect program as a quasi-natural experiment, we assess the impact of stock market liberalization on corporate innovation. The baseline result based on a difference-in-differences (DID) estimation suggests that allowing foreign investors to buy domestic stocks has a beneficial effect on Chinese firms' innovative outputs. Specifically, eligible firms affected by the Stock Connect scheme generate more and higher quality patents than other unaffected firms subsequently. Furthermore, we explore potential channels that may explain this beneficial effect in terms of improving corporate governance, reducing information asymmetry, and mitigating financial constraints. In addition, the effect is more pronounced for firms in high-tech industries. However, we find that the influence of stock market liberalization is insignificant in state-owned firms. Besides, the findings are generally robust to different measures of innovation and different methods of estimation. Overall, this paper provides new insights into understanding the positive effect of stock market liberalization in emerging market economies.     

The differentiated effect of advertising on readership: evidence from a two-sided market approach

In this paper, we empirically analyze the French print media market by modeling the existence of a reciprocal effect between the size of the readership and the amount of advertising. For this two-sided platform, we measure the cross-effects of advertising on the readership and periodical popularity on advertising. By estimating a structural model of simultaneous demand equations, we quantify some crucial elements in designing pricing and product-differentiating strategies. We measure the impact of advertising on reader demand and find in the data that it has opposite effects depending on whether the publication presents informational or entertaining content. By taking into account the market interactions, we compute price and advertising elasticities. Our results show that advertisers targeting a specific category of the audience would choose its corresponding periodicals and would trade off the size of the readership for these periodicals and the advertising insert price changes. Also, advertising campaigns aimed at reaching a broader spectrum of the population should focus on popular titles and on titles for which demand is inelastic to ensure a more consistent impact of the campaign. Finally, for magazines with low price demand elasticity on the readers’ side, editors’ revenues could be improved by increasing prices. These combined effects should allow a publisher to generate positive margins from both sides of the market, for certain content categories.     

Value relevance of blog visibility

This study empirically examines the effect of a non-traditional information source, namely a firm's blog visibility on the capital market valuation of firms. After controlling for earnings, book value of equity and other value relevant variables, such as traditional media exposure, R&D spending, and advertising expense, we find a positive association between a firm's blog visibility and its capital market valuation. In addition, we find blog visibility Grange causes trading, not vice versa. Our findings indicate that non-traditional information sources such as blogs help disseminate information and influence consumers' investment decisions by capturing their attention.     

Do cross-border mergers and acquisitions increase short-term market performance? The case of Chinese firms

Despite the new momentum in cross-border mergers and acquisitions (M&As) by emerging market firms, we have a limited understanding of the impact of these activities. Drawing on signalling theory and the institution-based view, this paper examines the extent of stock market reactions to the announcement of cross-border M&A deals, based on an event study of a sample of Chinese firms during the period 2000–2012. The findings indicate that the announcement of cross-border M&As results in a positive stock market reaction; this effect is more significant in the mainland Chinese stock markets (Shanghai and Shenzhen) than that in the Hong Kong market. The shareholders of Chinese firms that acquire a target firm in a host country with a low level of political risk gain higher cumulative abnormal returns than those firms targeting companies in countries with a high level of political risk. The shareholders of Chinese state-owned enterprises experience lower abnormal returns compared with those of Chinese privately owned firms when engaging in cross-border M&A deals.     

Valuation uncertainty,home and host market uncertainty,and cross-border seasoned equity offerings

This study examines how market timing can affect host market reaction to cross-border seasoned equity offerings (SEOs), an event generally viewed unfavorably by investors. We assume that firms engage in market timing in response to valuation uncertainty (VU), home market uncertainty (HMU) and/or host market uncertainty (HSU), and that raising capital abroad faces higher scrutiny costs and familiarity bias from host market investors. We conjecture that timing strategies provide signals that vary in strength to host market investors and that dual-timing strategies may strengthen an existing signal. Our hypotheses are tested on a sample of 190 cross-border SEOs that were issued on the U.S. stock market between 1990 and 2017 by firms from 29 countries. Using event study methodology, we find that market timing based on VU is negatively related to host market valuation and that a dual-timing strategy with HMU or HSU generally produces a stronger signal. Our results have practical relevance for stock markets that suffer from high uncertainty; we estimate that a high VU firm with a $1 billion valuation suffers a drop of $31.3 million in market valuation during a high host market uncertainty (high HSU) compared with low host market uncertainty (low HSU).     

An empirical analysis of national and local advertising effect on price elasticity

This paper investigates the interaction effect of advertising and price on the market share of a consumer nondurable product. We postulate a model in which local advertising is thought to primarily affect the consumers' purchase by making the demand more price sensitive, and national advertising to affect the consumers' preference, thus making the demand less price sensitive. Moreover, we hypothesize that local advertising interaction will have more immediate effect, while national advertising interaction will have longer term interaction effects. We apply these ideas empirically, and find support for our hypotheses. Thus, the interaction effect of advertising and price can be characterized by both increased and decreased price sensitivity, depending on the type of advertising. Moreover, these effects may be present simultaneously for the same product.
