Network formation models with costs for establishing links

Abstract. In this paper we study endogenous formation of communication networks in situations where the economic possibilities of groups of players can be described by a cooperative game. We concentrate on the influence that the existence of costs for establishing communication links has on the communication networks that are formed. The starting points in this paper are two game-theoretic models of the formation of communication links that were studied in the literature fairly recently, the extensive-form model by Aumann and Myerson (1988) and the strategic-form model that was studied by Dutta et al. (1998). We follow their analyses as closely as possible and use an extension of the Myerson value to determine the payoffs to the players in communication situations when forming links is not costless. We find that it is possible that as the costs of establishing links increase, more links are formed.     

Consumer Socialization and the Role of Branding in Hazardous Adolescent Drinking

This study examines the relationship between alcohol marketing and consumer socialization to alcohol brands (assessed here using aided and unaided brand recognition and brand saliency), and the associated relationship between consumer socialization and hazardous alcohol consumption among a cohort of adolescents surveyed in Scotland. The research addresses gaps in the consumer socialization literature, by examining how marketing influences brand consumer socialization, and how brand consumer socialization influences subsequent hazardous consumption behavior over time, using a robust longitudinal design that assesses causal relationships while controlling for a wide range of important confounding variables. The results demonstrate the contribution of marketing to adolescents’ brand socialization to alcohol and the impact of this socialization on subsequent drinking behaviors. Implications for marketing managers, parents, policymakers, and consumer researchers are discussed, together with suggestions for future consumer research.     

An enduring need: multilateralism in the twenty-first century

That the global economy has been hugely successful over thepast 50 years is unquestionable. A major underpinning of thatsuccess has been the open multilateral system, which has enabledthe emergence of a truly international financial system, reciprocalreduction of trade barriers, and the emergence of many previouslypoor countries into the status of ‘emerging markets’or even ‘developed’. The open multilateral system,however, is increasingly under-appreciated and taken for granted.Preferential trading arrangements have proliferated, and withthem the possibility of discriminatory arrangements for capitalflows. The absence of an international regime for capital flowspermits this development and poses a threat to the system, asdo all of the issues on which countries' governments assert‘their’ interests, and ignore their interests inthe overall health of the system. It is to be hoped that thebenefits of multilateralism are more greatly appreciated, andthat the current trend toward increasing regionalism and departuresfrom the post-war system is reversed.     

Discussion of “biases in multi-year management financial forecasts: Evidence from private venture-backed U.S. companies”

Armstrong, Dávila, Foster, and Hand (“ADFH”) use a proprietary venture capital database of revenue and profit projections submitted by young firms seeking financing to attempt to address a number of questions related to forecasts by managers of early stage, venture-backed, private entrepreneurial firms. The proprietary dataset together with the creative use of a “historically-grounded conditional projections” methodology are the most interesting features of ADFH’s study. However, these same aspects give rise to empirical design constraints that the study does not fully overcome. In addition, there are numerous leaps of logic required to arrive at some of ADFH’s conclusions and there are alternative explanations for ADFH’s findings that have not been entirely refuted. This leaves the reader with some doubt as to whether all of ADFH’s conclusions are fully substantiated. Nevertheless, the evidence presented makes an interesting contribution to our understanding of the forecasting behavior of young, private, rapidly growing, VCbacked firms, and provides some natural economic and methodological leads into further studies of these issues.     

Can You Hear Me Now? Communication in Virtual Product Development Teams*

Globalization and technological advances are driving organizations to extend the boundaries of new product development (NPD) teams from traditional colocated settings to dispersed or virtual settings. Virtual NPD teams have a wide array of information and communication technologies (ICTs) at their disposal. ICTs allow team members to communicate and collaborate as they cope with the opportunities and challenges of cross‐boundary work. The purpose of this paper is to explore ICT use by members of virtual NPD teams. This study presents an exploratory test and integration of two competing perspectives of media use in virtual teams: media capacity theories and social dynamic media theories. Specifically, this paper examines the role of task type, organizational context, and ICT type as critical contingency variables affecting ICT use. It also examines how different patterns of ICT use relate to individual perceptions of team performance. The findings from this study of 184 members of virtual NPD teams in three global firms suggest that communication via ICTs in virtual NPD teams is contingent on a range of factors.
