This article introduces "career entrepreneurship," a rapidly spreading phenomenon in the global knowledge-driven economy. Career entrepreneurship involves taking an entrepreneurial approach to managing our careers. It means doing things that seem "illegitimate" to other people and contradict socially-recognized and accepted sequences of work experiences in terms of age, education, or socio-economic progression. This kind of behavior challenges established norms about typical career development. The evidence presented in this article suggests new possibilities for thinking about the way individuals invest in their careers, new insights for organizations interested in capturing the potential of career entrepreneurship, and new ideas for career and life coaches to support people embracing the phenomenon. The article offers a primer on career entrepreneurship to all three groups of readers, calling for more effective collaborative relationships and more effective leveraging of individuals' career investments.

The existing literature identifies patent thickets indirectly. In this paper we propose a novel measure based on patent citations which allows us to measure the density of patent thickets directly. We discuss the algorithm which generates the measure and present descriptive results validating it. Moreover, we identify technology areas which are particularly impacted by patent thickets.

We study competitive market outcomes in economies where agents have other-regarding preferences (ORPs). We identify a separability condition on monotone preferences that is necessary and sufficient for one's own demand to be independent of the allocations and characteristics of other agents in the economy. Given separability, it is impossible to identify ORPs from market behaviour: agents behave as if they had classical preferences that depend only on own consumption in competitive equilibrium. If preferences, in addition, depend only on the final allocation of consumption in society, the Second Welfare Theorem holds as long as any increase in resources can be distributed in a way that makes all agents better off. The First Welfare Theorem generally does not hold. Allowing agents to care about their own consumption and the distribution of consumption possibilities in the economy, the competitive equilibria are efficient given prices if and only if there is no Pareto-improving redistribution of income.

On October 26, 2004, Norman Nicholls - partner of the consulting company "Seattle Management Consultants" in London (UK) - received a phone call from Jesper Lind, board member of Telco-Equipment-Experts. Jesper told Norman: "If you don't change your recommendation on the outsourcing job you are doing for Damotel, our business relationship might suffer in the future."

We examine a multinational firm which has a decreasing marginal cost, and the optimal sales tax policies of the regions where that firm operates. We show that the regions set higher sales taxes than those given by a cooperative equilibrium. Each region fails to fully internalize the effects of its tax level on another region's welfare and the incentives for that region's authority. Exponential cost functions which exhibit economies of scale (for example Cobb-Douglas) and linear demand functions satisfy our assumptions. Our results suggest the need to coordinate sales tax levels between countries and between smaller entities, like states in the United States. Smaller regions benefit more from such coordination. Lowering sales taxes in each region increases welfare for all regions, profits for firms, and consumer welfare.

This paper analyses how different types of access regulation to next generation networks affect investments and consumer welfare. The model consists of an investment stage with uncertain returns and subsequent quantity competition. The access price is a function of investment costs and the regulatory regime. A regime with fully distributed costs or a regulatory holiday induces highest investments, followed by risk-sharing and long run incremental costs regulation. Simulations indicate that risk-sharing creates most consumer welfare, followed by regimes with fully distributed costs, regulatory holiday and long run incremental costs, respectively. Risk-sharing benefits consumers as it combines relatively high ex-ante investment incentives with strong ex-post competitive intensity.

The case describes the situation of Dirk von Ameln, permitting director of Nord Stream, in his negotiation efforts to obtain the necessary national permits for the construction of the Nord Stream pipeline. In order to obtain the Danish construction permit, Dirk von Ameln has to reach an agreement with the Danish fishermen, who fear a negative impact on their trade from the construction and operation of the pipeline. The case can be used in its two-party form for introductory negotiation courses. It serves multiple objectives, among them: 1. to understand the steps in preparing negotiations (defining own interests, improving own alternatives, determining the other party's best alternative to a negotiated agreement (BATNA), defining a win set and the objective for the negotiation); 2. to understand the difference between distributive and integrative negotiations, specifically to demonstrate the potential for joint value creation in negotiations with public authorities; 3. to understand the process of negotiation in European cross-border infrastructure projects and its implications on developing company competencies such as management of permitting and communication; and 4. to analyze different approaches to negotiations and their implication on current negotiation strategies and future negotiations and relationships.
