When does universal peace prevail? Secession and group formation in conflict

This paper analyzes secession and group formation in the general model of contests due to Esteban and Ray (1999). This model encompasses as special cases rent seeking contests and policy conflicts, where agents lobby over the choice of a policy in a one-dimensional policy space. We show that in both models the grand coalition is the efficient coalition structure and agents are always better off in the grand coalition than in a contest among singletons. Individual agents (in the rent seeking contest) and extremists (in the policy conflict) only have an incentive to secede when they anticipate that their secession will not be followed by additional secessions. Incentives to secede are lower when agents cooperate inside groups. The grand coalition emerges as the unique subgame perfect equilibrium outcome of a sequential game of coalition formation in rent seeking contests.

Cohesion Policy in the eu: Going Beyond Fiscal Transfers?

Should cohesion policy in the EU be reformed? This question becomes pressing in light of the coming enlargement of the EU. Indeed, without reform enlargement will involve an increase in the budget for cohesion policies, as well as a reallocation of funds across regions. Furthermore, it is an appropriate occasion to rethink the various rules and criteria associated with cohesion policies. Recently, the European Commission published its Second Report on Economic and Social Cohesion (henceforth SRESC, (2001)). The report praises the effectiveness of current cohesion policies and suggests a mere continuation of current practices in the future. This paper challenges this conclusion and discusses some options for reform. The paper starts with a brief introduction to the current cohesion policy and the changes that will occur in light of EU enlargement. Subsequently, we address two questions. Is there a need for cohesion policy reform? And if so, how should it be reformed?     

Entry and Competition in the Postal Market: Foundations for the Construction of Entry Scenarios*

This paper presents a model of entry and imperfect competition, which is inspired by the product differentiation literature and incorporates facts pertaining to the postal sector. There are two operators: incumbent and potential entrant. The entrant offers only one of the products (commercial mail) with a specific technology and delivers only to part of the addressees (located in low cost areas). Its degree of coverage is viewed as a quality attribute; it affects demand and hence market share. The incumbent faces a USO while the entrant is an unregulated profit maximizing firm. To illustrate the potential applications of our approach, we provide some numerical simulations of entry scenarios.     

Ubiquitous computing and its effects on small businesses

Much of the previous literature on ubiquitous computing (UbiComp) has been limited to case studies, reporting innovative practices of specific technologies (e.g., RFID) and social issues. There is a general paucity of research on strategic application of UbiComp, especially to small businesses. To address this issue, this study provides a broad overview of the current practices of UbiComp in leading countries and presents possible future directions. Then, the effects of UbiComp on small businesses are discussed. Through a cross-national comparative analysis, we present four strategies to provide some guidance to the countries that are currently considering entering into the UbiComp race.     

Corporations as Political Actors – A Report on the First Swiss Master Class in Corporate Social Responsibility

This paper presents a report on the first Swiss Master Class in Corporate Social Responsibility, which was held between the 8th and 9th December 2006 at HEC Lausanne in Switzerland. The first section of the report introduces the topic of the master class – ?Corporations as Political Actors – Facing the Postnational Challenge’ – as well as the concept of the master class. The second section gives an overview of papers written by nine young scholars that were selected to present their research. The brief summary of each paper also includes a summary of comments from the masters, practitioners, and NGO representatives at the event. The third section brings in the perspectives of one master and one NGO representative on the discussed issues. The final section offers a brief wrap-up of the discussed topics and outlines ways to structure future conceptual and empirical research.     

Employee ambidexterity,high performance work systems and innovative work behaviour: How much balance do we need?

Abstract

This study examines whether and how innovative work behaviour is related to explorative and exploitative activities. Polynomial regression analyses are used to test the relationship between ambidexterity (being engaged in explorative and exploitative activities in equal amounts) and innovative work behaviour, as well as between specialisation (being engaged in either explorative or exploitative activities) and innovative work behaviour. Furthermore, we use moderated polynomial regression analyses to examine a possible moderating effect of high-performance work systems (HPWS) on these relationships. Results indicate that balance at a high level, as well as specialisation, are conducive to innovative work behaviour. A moderating effect of HPWS was not supported by our data.     

Lange's 1938 model: dynamics and the “optimum propensity to consume”

Abstract

Oskar Lange's 1938 article “The Rate of Interest and the Optimum Propensity to Consume” is usually associated with the original IS-LM approach of the late 1930s. However, Lange's article was not only an attempt to illuminate Keynes's main innovations but the first part of a wide project that included the development of a theory of economic evolution. This paper aims at showing that Lange's article can help in illuminating critical aspects of this project: in particular, Lange's idea that a synthesis between Kaldor's and Kalecki's theories and that of Schumpeter, might have been possible and that it represented (in intentions) a “modern” and consistent reconstruction of the Marxist theory of the business cycle. Section 2 clarifies Lange's early reflection on dynamics. Section 3 centres on Lange's 1938 static model and indicates the effects of a change of saving on investment. Section 4 suggests a dynamic reconstruction from which are addressed important arguments raised by Lange in a series of papers written between 1934 and 1942.     

Cognitive function, numeracy and retirement saving trajectories

This paper examines the extent to which cognitive abilities relate to differences in trajectories for key economic outcomes as individuals move towards and through their retirement. We look at whether differences in baseline numeracy (measured in the English Longitudinal Study of Ageing in 2002) and broader cognitive ability predict the subsequent trajectories of outcomes such as wealth, retirement income and key dimensions of retirement expectations. Those with lower numeracy are shown to have different wealth trajectories both pre- and post-retirement than their more numerate counterparts, but the distributions of retirement expectations and net replacement rates are similar across numeracy groups.     

Legitimacy-Seeking Organizational Strategies in Controversial Industries: A Case Study Analysis and a Bidimensional Model

Controversial industry sectors, such as alcohol, gambling, and tobacco, though long-established, suffer organizational legitimacy problems. The authors consider various strategies used to seek organizational legitimacy in the U.K. casino gambling market. The findings are based on a detailed, multistakeholder case study pertaining to a failed bid for a regional supercasino. They suggest four generic strategies for seeking organizational legitimacy in this highly complex context: construing, earning, bargaining, and capturing, as well as pathways that combine these strategies. The case analysis and proposed bidimensional model of generic legitimacy-seeking strategies contribute to limited literature on organizational legitimacy in controversial industry sectors. In addition, beyond organizations active in controversial contexts, this study and its implications are useful for individuals and organizations supporting or opposing the organizational legitimacy of organizations in controversial industries.
