FIRM SIZE AND STOCK RETURNS: A QUANTITATIVE SURVEY

Firm size is commonly used in numerous empirical asset pricing models as a determinant of expected stock returns. Yet there is little consensus over the magnitude and stability of the size premium. In fact, some researchers even question whether firm size should be used as a pricing factor. We collect 1746 estimates of the slope coefficients capturing the association between firm size and stock returns reported in 102 published studies and conduct the first meta‐analysis on the size premium. We find evidence of a strong bias toward publishing statistically significant negative slope coefficients. After correcting for the bias, we find that the literature implies a difference in annual stock returns on the smallest and the largest New York Stock Exchange (NYSE) market capitalization quintiles of 1.72%. For the time periods covered in the sampled articles, we find that the size premium was larger in earlier years and that the intensity of publication bias has been decreasing over time.     

Chaebol-affiliated analysts: Conflicts of interest and market responses

Some Korean business groups, or chaebols, have a large stake in securities firms that issue analysts’ reports on their member companies. This structure is unique in that industrial companies and securities firms are affiliated and operate within the same group. We investigate the informational content of earnings forecasts, stock recommendations and target prices made by the chaebol-affiliated analysts, using data collected between 2000 and 2008. The chaebol analysts tend to make more optimistic earnings forecasts for the member companies. The mean EPS forecast error (5.36%) of the affiliated analysts for the same chaebol company are significantly larger than that (3.23%) of other chaebol and independent analysts. The chaebol analysts also assign better recommendations by almost one level and set target prices 2.5% higher to the member companies after controlling for company and analyst characteristics. These results are consistent with the hypothesis that chaebol analysts’ reports are biased by conflicts of interest. Stock market reactions do not differ in response to announcements of stock recommendations issued by affiliated vs. non-affiliated analysts. This suggests that capital markets do not recognize the conflicts of interest inherent in chaebol analysts’ reports.     

R&D management through network mapping: using the Internet to identify strategic network actors in cooperative research networks

Most R&D management techniques to date have emphasized the immediate organizational context or the internal structure and process of the R&D project. Recently however attempts have been made at situating R&D management in a wider context of inter‐organizational R&D activities. This paper presents the technique of R&D network mapping as a means of providing strategic intelligence to the R&D manager. The paper backgrounds this technique with a discussion of the general issue and significance of R&D networks. A methodology for R&D network mapping is then exemplified by outlining how a network database of cooperating projects and institutes in the telecom research sector was built by utilizing the World Wide Web. Finally a number of suggestions are made as to how and when network mapping should be applied in strategic R&D management.     

American stochastic volatility call option pricing: A lattice based approach

This study presents a new method of pricing options on assets with stochastic volatility that is lattice based, and can easily accommodate early exercise for American options. Unlike traditional lattice methods, recombination is not a problem in the new model, and it is easily adapted to alternative volatility processes. Approximations are developed for European C.E.V. calls and American stochastic volatility calls. The application of the pricing model to exchange traded calls is also illustrated using a sample of market prices. Modifying the model to price American puts is straightforward, and the approach can easily be extended to other non-recombining lattices.     

Innovativeness: Its antecedents and impact on business performance

In this study, we address three research questions: (1) Why are some industrial firms more innovative than others? (2) What effect does innovativeness has on business performance? (3) Does the linkage between innovativeness and business performance depend on the environmental context? Accordingly, we draw on various theoretical perspectives to develop hypotheses that propose market orientation, entrepreneurial orientation, and learning orientation as key antecedents to innovativeness, as well as a direct relationship between innovativeness and business performance. A model is devised and tested that examines these relationships in general and in the context of varying market turbulence. Findings confirm the validity of the model and afford various insights on the role of market turbulence in the proposed relationships. Lastly, implications are offered on the antecedents and consequences of organizational innovativeness.     

Leadership, the buying center, and supply chain performance: A study of linked users, buyers, and suppliers

With conceptual foundations taken from leadership theory and the resource-based view (RBV), this study examines the influence of transactional and transformational leadership on the relationship between the value of the corporate buying center and performance in supply chains. The sample consists of 58 directly linked and matched supply chains, each composed of one user (internal customer), one corporate buyer, and one external supplier. The results indicate that transformational leadership has a positive moderating effect on the relationship between the value of the corporate buying center and performance, while transactional leadership negatively moderates this relationship. Two “localness” dimensions (formalization and centralization) and two “openness” dimensions (participative and reflective) were included as controls in the analysis.     

Examining a key corporate role: The influence of capital allocation competency on business unit performance

Research on the role of the corporate office in firm performance has focused on establishing how much performance variance can be attributed to a “corporate effect,” with little attention devoted to understanding how this influence occurs. In this study, we model capital allocation competency as a dynamic managerial capability and find that lower levels of allocation competency in the form of excess investment to business units with relatively poorer future prospects reduce business unit performance. We also find that market conditions affect performance implications of capital allocation—allocation competency is more salient in more competitive markets. These results enhance our understanding of how the corporate office influences business unit performance through its role in allocating capital across business units.

An application of finite elements to option pricing

This study applied the finite element method (FEM) to pricing options. The FEM estimates the function that satisfies a governing differential equation through the assembly of piecewise continuous functions over the domain of the problem. Two common representations, a variational functional representation, and a weighted residual representation are used in the application of the method. The FEM is a versatile alternative to other popular lattice methods used in option pricing. Advantages include the abilities to directly estimate the Greeks of the option and allow nonuniform mesh construction. As an illustration of the advantages that the FEM offers, the method was used to price European put options and discrete barrier knock‐out put options. © 2001 John Wiley & Sons, Inc.

An analysis of the liquidity benefits provided by secondary markets

Listing shares in liquid secondary markets either to facilitate acquisitions or to diversify owner’s personal wealth are among the most important reasons for firms to go public [Brau, J.C., Fawcett, S.E., 2006. Initial public offerings: An analysis of theory and practice. Journal of Finance 61, 399–436]. We contend that the expected benefits derived from the liquidity provided by secondary markets are relevant for understanding important decisions made in preparation for an IPO. We hypothesize that the potential losses caused by an IPO failure induce firms that benefit more from going public to hire more reputable underwriters and to adopt more conservative pricing policies. We use several proxies for the benefits firms derive from post-IPO liquidity. The results indicate that firms that benefited more from liquidity were taken public by more prestigious underwriters and exhibited substantially larger levels of price revisions and underpricing. Post-IPO liquidity is also important for understanding the decision to retain the lead underwriter in subsequent SEOs.     

Big splash,no waves? Cognitive mechanisms driving incumbent firms’ responses to low‐price market entry strategies

Research Summary: Low‐price market entries, aiming for rapid sales growth, tend to prompt strong competitive reactions. This research explores whether and how firms using low‐price entry strategies can mitigate retaliatory incumbent reactions. An experiment with 656 managers shows that entrants can attenuate the strength of incumbents’ responses by fostering perceptions of high aggressiveness or low commitment. Entrants may be able to accomplish this by adjusting their entry strategy to embed (subtle) cues of aggressiveness and (lack of) commitment. A replication experiment with university students reinforces our overall theoretical argument. However, the results also indicate that the interpretation of cues embedded in the entry strategy may be affected by the experience of incumbent firm managers. Overall, these results clarify the cognitive foundations of competitive responses to market entry. Managerial Summary: What drives incumbents to respond strongly to market entries, and what can the entrant, if anything, do to mitigate those responses? This research offers empirical evidence and theoretical insights for managers faced with these questions by shedding light on the thinking processes preceding competitive responses. The study shows that while managers are motivated to respond strongly to market entries that appear to be highly consequential to their business, these responses may be mitigated if the entrant manages to foster perceptions of high aggressiveness or low commitment to the market. Managers form these perceptions in part on the basis of the entrant’s behavior, creating an opportunity for entrants to adjust their entry strategies in a manner that demotivates strong competitive responses.
