The elephant in the room of Dynamic Capabilities: Bringing two diverging conversations together

Abstract: A critical issue has been absent from the conversation on dynamic capabilities: the two seminal papers represent not only diverging but seemingly incompatible understandings of the framework. Here,...

Towards an understanding of the phases of goodwill accounting in four Western capitalist countries: From stakeholder model to shareholder model

Abstract: The objective of this paper is to illustrate that the change in shareholders' attitude towards firms (from stakeholder model to shareholder model) influences the accounting treatments of goodwill. Our study is based on four countries (Great Britain, the United States, Germany, and France) and covers more than a century, starting in 1880. We explain that all these countries have gone through four identified phases of goodwill accounting, classified as (1) "static" (immediate or rapid expensing), (2) "weakened static" (write-off against equity), (3) "dynamic" (recognition with amortization over a long period) and (4) "actuarial" (recognition without amortization but with impairment if necessary). We contribute several new features to the existing literature on goodwill: our study (1) is international and comparative, (2) spans more than a century, (3) uses the stakeholder/shareholder models to explain the evolution in goodwill treatment in the four countries studied. More precisely, it relates a balance sheet theory, which distinguishes four phases in accounting treatment for goodwill, to the shift from a stakeholder model to a shareholder model, which leads to the preference for short-term rather than long-term profit, (4) contributes to the debate on whether accounting rules simply reflect or arguably help to produce the general trend towards the shareholder model, (5) demonstrates a "one-way" evolution of goodwill treatment in the four countries studied, towards the actuarial phase.

In Charisma We Trust: The Effects of CEO Charismatic Visions on Securities Analysts

Abstract: Using a thematic text analysis of the initial letters to shareholders following a CEO succession event, we analyze whether CEO charismatic visions portrayed in this organizational discourse influence securities analysts' recommendations and forecasts. The results suggest that such projections of CEO charismatic visions are associated with the favorability of individual analyst recommendations and the uniformity of recommendations across analysts, but they also appear to be positively related to errors in individual analysts' forecasting of future firm performance.

The Effects of Problem Structure and Team Diversity on Brainstorming Effectiveness

Abstract: Since Osborn's Applied Imagination book in 1953 (Osborn, A. F. 1953. Applied Imagination: Principles and Procedures of Creative Thinking. Charles Scribner's Sons, New York), the effectiveness of brainstorming has been widely debated. While some researchers and practitioners consider it the standard idea generation and problem-solving method in organizations, part of the social science literature has argued in favor of nominal groups, i.e., the same number of individuals generating solutions in isolation. In this paper, we revisit this debate, and we explore the implications that the underlying problem structure and the team diversity have on the quality of the best solution as obtained by the different group configurations. We build on the normative search literature of new product development, and we show that no group configuration dominates. Therefore, nominal groups perform better in specialized problems, even when the factors that affect the solution quality exhibit complex interactions (problem complexity). In cross-functional problems, the brainstorming group exploits the competence diversity of its participants to attain better solutions. However, their advantage vanishes for extremely complex problems.

Network resource stocks and flows: how do alliance portfolios affect the value of new alliance formations?

Abstract: We examine how new network resources accessed through alliance formations interact with network resources present in a firm's alliance portfolio. We test our theoretical model using event study methodology and data from the global air transportation industry. We find that the market rewards firms forming alliances that contribute resources that can be synergistically combined with firms' own resources as well as with network resources accessed through their alliance portfolios. Our results also indicate that the market penalizes firms entering into alliances that create resource combinations that are substitutes to resource combinations deployed by existing alliance partners.
