This study investigates delisting avoidance on an exchange as a motivation for reverse stock splits. I examine the different motivations for reverse splits for stocks at different pre-split price levels by dividing the sample into two groups, below or equal to 2, and above . Using a control sample of firms receiving delisting warnings, I find that firms on the brink of delisting, use reverse splits to extend exchange listing time. For firms with a pre-split price above $2, I find that liquidi...

Purpose - Using the economic policy uncertainty (EPU) index as a proxy for the level of EPU, we study the impact of the level of EPU on the conditional mean of market returns and we examine the predictive power of EPU on future market returns. Design/methodology/approach - We employ a GARCH-in-Mean model with exogenous variables. Findings - The results show that even after controlling for business cycle effects, EPU is inversely related to contemporaneous market returns. Particularly, the author...

Abstract In this study, we reexamine the link between a firm’s market share and its idiosyncratic volatility. Contrary to extant research, we find that market share is not a determinant of idiosyncratic volatility. Innovative firms continuously innovate resulting in an increase in market share. However, high market share firms may not necessarily increase investment in innovative ventures to maintain market share. Hence an increase in market share does not necessarily lead to an increase in a fi...

This study, using a fixed effects model, empirically investigates the relationship between corporate governance and corporate performance dispersion. Suggesting a negative relationship, [1] theorize that when corporate governance improves there is a decrease in shareholder oversight which could permit greater managerial discretion to execute conservative investment policies leading to a decrease in corporate risk taking and hence a decrease in performance dispersion. For a positive link, [2], em...

In this study, we examine the relationships among political cycles, investor sentiment, and stock market returns. We uncover that the variable: change in investor sentiment levels, is a mediator for the relationship between political cycles and stock market returns. We establish that political cycles impact stock market returns through two channels. First, there is a direct impact of fiscal and regulatory policies on corporate fundamentals which is reflected in stock prices, and second, there is...

This study compares the two primary measures of corporate governance quality, [1], GIM index and [2] E index using tests for comparing two nonnested models. We find that the GIM index has statistically significantly more power than the E index in explaining the variability in firm value, as measured by Tobin’s Q. This finding suggests that the IRRC provisions excluded from the E index may have a statistically significant incremental power in explaining the variability in firm value.

Social networking sites are important to firms as firms use them to communicate with their customers. This study investigates the overlooked collateral damage (the accidental negative outcomes that occur when customers communicate with each other via social networking sites) that customer-to-customer communications, through social networking, has for firms. Based on 3 experimental surveys with 614 participants, we found that information that is received publicly by way of social networking sites...

Although online communities of counterfeit consumption (OCCC) enhance the demand for counterfeit products, research that improves marketers' understanding of this phenomenon is lacking. This article's purpose is to investigate how online communities of consumption have transformed the acquisition, sharing, and processing of information by consumers of counterfeits. Through the use of netnography in an online counterfeit watch community, this work identifies four themes as factors that draw consu...
