Choosing the right target: Relative preferences for resource similarity and complementarity in acquisition choice

Research summary : Corporate acquisition is a popular strategic option for firms seeking new resources. However, little research exists on the question of why one firm is chosen over another. We develop a model relating characteristics of similarity and complementarity between acquirers' and target firms' key resources, including their products and R&D pipelines, to the likelihood of the acquirers choosing a particular firm. We construct measures of similarity and complementarity between and across products and R&D pipelines, and test their effects using a novel application of the choice model. Findings reveal that acquirers view similarity and complementarity differently, based on the resource they are comparing. When making comparisons to their own R&D pipelines, acquirers prefer similarity over complementarity whereas when making comparisons to their product portfolios, they prefer complementarity over similarity. Managerial summary : Corporate acquisition is a popular way for firms to grow and obtain innovative resources. However, we know little about why acquirers choose one firm over another. We capture the influence of similarity and complementarity between acquirers' and target firms' products (current innovative value) and R&D pipelines (future innovative value) on whether a particular target firm is acquired. Insights from the pharmaceutical industry reveal that acquirers value similarity and complementarity in target firms differently, based on whether the comparison being made is with respect to their products or their R&D pipelines. Regarding their R&D pipelines, acquirers prefer that the target firm has similar, rather than complementary, resources. However, the opposite is true concerning their own products: acquirers prefer that the target firm has complementary, versus similar, resources. Copyright © 2015 John Wiley & Sons, Ltd.     

Managerial Behavior and the Link between Stock Mispricing and Corporate Investments: Evidence from Market‐to‐Book Ratio Decomposition

We examine the impact of mispricing on corporate investments and its components: capital expenditures, research and development, acquisitions, and asset sales. By decomposing the market‐to‐book ratio into mispricing and growth components, we show that corporate investments are linked to mispricing through market‐timing and catering, after controlling for growth and financial slack. This investment‐mispricing link is more pronounced in financially constrained firms and in firms with short‐horizon shareholders. Overall, our study indicates that the sensitivity of investments to mispricing is a function of the nature of mispricing, the type of investment, and the firm's characteristics.     

The announcement impact of seasoned equity offerings on bondholder wealth

Previous studies document a negative return to equity on the announcement of an SEO. However, the effects of SEO announcements on bonds have received little attention. We find that bondholders experience a significant positive return on the announcement of an SEO and this effect is more pronounced for bonds with lower ratings. We examine alternate explanations for bond market reactions to SEO announcements including the leverage risk reduction, wealth transfer, and information signaling hypotheses. Overall, our results are most consistent with the leverage risk reduction hypothesis.     

Machiavellianism in public accountants: some additional Canadian evidence

The current study surveys practising Canadian public accountants in Canada in both Big 4 and non-Big 4 firms to determine their orientation with respect to Machiavellianism, defined as 'attending to one's interests much more than to others'. Results indicate that while there are no significant differences in Machiavellianism between public accountants in the upper-level positions (managers and partners), partners are significantly less Machiavellian than seniors. These results are consistent with previous studies on Canadian public accountants.     

民营书业竞争力研究

经过改革开放30年的不懈努力,民营书业获得了长足的发展,与国有书业一样,已经成为国内书业的重要组成部分.在民营书业的发展过程中,充分表现出产权明晰、机制灵活、服务优质等竞争优势,也暴露出社会信誉较差、经营规模较小、管理水平较低、人员素质不高等竞争劣势.民营书业必须重塑自身形象、引入现代企业制度、走专业化经营之路,方能进一步提升经营竞争力,实现可持续的大发展.     

立法时机决策论——《劳动合同法》引发的思考

立法时机是指立法者做出是否立法以及何时立法的决策时所应考虑的各项主客观条件。立法需求和立法可能是正确地决策立法时机的两大要素。前者包括社会关系的广度、深度等三个层面,后者则涵盖了立法能力等三个层面。     

Performance monitoring in R&D projects

Project Management Systems can use a variety of tools to model and visualise project status. This paper discusses the application of an integrated approach for project modeling and proposes a new graphic tool called PACT for evaluation of project status. An integrated performance monitoring system comprising many tools, including PACT, was used successfully with multiple advanced technology projects within the Indian Guided Missiles Development Programme. The approach provided a better insight into the status and problems of projects, and enabled management to initiate the most appropriate actions towards better performance.     

Do Spin‐offs Expropriate Wealth from Bondholders?

A wealth transfer from bondholders to stockholders is one of several hypotheses used to explain stockholder gains on the announcement of a spin‐off. However, previous empirical research has not found systematic evidence supporting the wealth expropriation hypothesis. Using a larger sample with comprehensive bond data, we find evidence consistent with wealth expropriation. Bondholders, on average, suffer a significant negative abnormal return during the month of the spin‐off announcement. However, even accounting for the loss to the bondholders, the aggregate value of the publicly traded debt and equity increases on a spin‐off announcement, suggesting that the wealth expropriation hypothesis is not a complete explanation of the stockholder gains. In explaining the magnitude of the losses to bondholders, we find they are a function of the loss in collateral in the spun‐off subsidiary and the level of financial risk of the parent firm. Consistent with a loss to bondholders, firms are more likely to have their credit rating downgraded than upgraded after a spin‐off. Additionally, consistent with the wealth transfer hypothesis, losses to bondholders tend to be more severe, the larger the gains to shareholders.
