Greater downside risk aversion in the large

In this paper, we advance a definition of greater downside risk aversion that applies to both large and small changes in risk preference, and thereby complements the results for small changes reported previously. We show that a downside risk-averse transformation of a utility function results in a function that is more downside risk averse in the same manner that a risk-averse transformation increases risk aversion. Our demonstration is conducted first by using the compensated approach introduced by Diamond and Stiglitz [P. Diamond, J. Stiglitz, Increases in risk and in risk aversion, J. Econ. Theory 8 (1974) 337-360] and then by using an adaptation of the risk premium approach taken by Pratt [J. Pratt, Risk aversion in the small and in the large, Econometrica 32 (1964) 122-136].     

Use transnational teams to globalize your company

The authors report on their two-year study of successful transnational teams, in which they examined how such teams are designed and managed to help their firms pursue global business strategies. Based on this study, they present a comprehensive model of team effectiveness that includes the key characteristics differentiating a transnational team from other types of work teams. The model shows how transnational teams operate—how they are staffed and led, communicate across great distances, and cope with cross-cultural issues. In closing, they describe how a company's human resources department can help an “international” or “multinational” team become a “transnational” team—one that has successfully transcended the cultural, geographic, and managerial barriers to team effectiveness.     

Real Earnings Management,Institutional Environment,and Future Operating Performance: An International Study

This paper investigates the association between firms' engagement in real activities manipulation (hereafter REM) on future firm performance in an international setting, and whether the association is conditional upon country-level institutional factor. Our inquiry is motivated by a paucity of research on the consequences of REM in an international setting. Using a large sample over the period of 2001 to 2015, we find that current-period REM is positively associated with future performance: a finding that is consistent with Gunny (2010) in the US. Importantly, we find that the positive performance effect is driven by firms operating in countries with strong institutional environments. Finally, we find that future operating performance improves when REM is undertaken by firms in strong institutional environments only during a non-economic crisis period, but not during an economic crisis period. The paper adds to the existing REM literature by showing a non-monotonic effect of REM on future performance that is conditional on the strength of a country's institution. We also contribute to the accounting information and crisis literature by documenting a time-variant effect of REM on future performance.     

Organizing Continuous Product Development and Commercialization: The Collaborative Community of Firms Model

The increased importance of knowledge creation and use to firms' global competitiveness has spawned considerable experimentation with organizational designs for product development and commercialization over the last three decades. This paper discusses innovation‐related organizational design developments during this period, showing how firms have moved from stand‐alone organizations to multifirm network organizations to community‐based organizational designs. The collaborative community of firms model, the most recent organizational design in this evolutionary process, is described in detail. Blade.org, a purposefully designed collaborative community of firms dedicated to the continuous development and commercialization of blade servers, a computer technology with large but unforeseeable market potential, is used as an illustrative case. Blade.org's organizational design combines a community “commons” for the collective development and sharing of knowledge among member firms with explicit institutional mechanisms for the support of direct intermember collaboration. These design elements are used to overcome the challenges associated with (1) concurrent technological and market experimentation and (2) the dynamic coordination of a complex emergent system of hardware, software, and services provided by otherwise independent firms. To date, Blade.org has developed more than 60 new products, providing strong evidence of the innovation prowess of the collaborative community of firms organizational model. Based on an analysis of the evolution of organizational designs and the case of Blade.org, implications for innovation management theory and practice are derived.
