Not All Ties Are Equal: CEO Outside Directorships and Strategic Imitation in R&D Investment:

Prior research has identified two different sources of strategic imitation—through perceived organizational cluster similarity (cluster effects) and direct social connections (tied-to effects). In the research on tied-to effects, top executives’ social ties, such as outside directorships, have long been studied as a mechanism through which strategic imitation develops. However, are all ties the same? There has been little examination of whether some social ties have more influence than others. Using the attention-based view of the firm, we argue that certain social ties garner more attention by being salient to top executives. We empirically test this assertion by examining the effects of CEO outside directorships on R&D spending. Using panel data from large U.S. manufacturing firms, we find that CEOs imitate the R&D intensity of tied-to firms (i.e., a firm in which the CEO serves as an outside board member) in their own firm’s R&D decisions. Consistent with attention-based arguments, our results show evidence of selective imitation, as imitating relationships are stronger when the CEO has longer tenure as a director of a tied-to firm and the tied-to firm is performing well. In contrast to conventional institutional theory, our findings also show that CEOs imitate relatively smaller tied-to firms when they make R&D investment decisions. Not all social ties have equal influence on imitative strategic decision making; thus, they have different strategic implications.

Complementary or Substitutive Effects? Corporate Governance Mechanisms and Corporate Social Responsibility

Management researchers have investigated how corporate governance mechanisms influence corporate social responsibility (CSR). The previous literature has been largely based on agency theory, which emphasizes the roles of effective monitoring and incentive alignment, but the empirical evidence has been mixed. This inconsistency may result from the assumption that each governance mechanism functions independently, even though they interact with one another to affect CSR. On the basis of a perspective of bundle of governance mechanisms, we examined whether multiple governance mechanisms act as complements or substitutes for each other in promoting CSR. Using a panel sample of U.S. firms for the years 2004 to 2010, we found that multiple governance mechanisms mainly act as substitutes to promote CSR. Our findings suggest that a similar level of CSR can be achieved with different combinations of governance mechanisms. Our study contributes to the fields of both corporate governance and CSR in theory and practice.

Interpreting Equivocal Signals Market Reaction to Specific-Purpose Poison Pill Adoption

Signaling theory suggests that firms send signals to stakeholders to reduce information asymmetry. Research, however, has rarely examined how investors interpret signals that are equivocal. We suggest that sensemaking serves as an important process by which investors interpret firm signals, and salient contextual cues influence the sensemaking process. We examine an equivocal signal, the adoption of a poison pill, as a means of examining investor interpretation of the signal and the role of contextual cues in influencing interpretation. Using a sample of 578 poison pill adoptions and controlling for self-selection, we find that investors react negatively to poison pills adopted to protect net operating losses (NOL poison pills) but positively to poison pills adopted when the firm is in receipt of a takeover offer (in-play poison pills). Assessing the role of contextual cues, our results suggest that CEO duality, the proportion of inside directors on the firm’s board, the firm’s R&D investments, and industry concentration also condition investor response to specific-purpose poison pill adoption. Our study contributes to research on signaling theory, sensemaking, and corporate governance by examining how investors interpret a firm’s equivocal governance decisions.

CSR Motive Attributions: The Roles of Executive Leadership Ethics and Consumer Cynicism

Consumers expect organizations to be socially responsible but, at the same time, have been shown to be skeptical of the motives behind corporate social responsibility (CSR) initiatives. This is bec...
