Turnpikes and detours in the renewable resource exploitation under price shocks

In this paper we show that the Averch-Johnson effect of overcapitalization by a regulated monopoly does not obtain when the firm operates in the decreasing cost range of output. We develop a dynamic adjustment-cost model of the firm and apply a recent result by Brock and Dechert for non-concave Hamiltonians to solve for the optimal investment policy for the firm. With a phase diagram analysis we are able to make sharp comparisons between the regulated and unregulated cases. In particular we show that investment by a regulated firm is lower than that of an unregulated firm, even when the rate of return constraint is not binding.     

Exploration,exploitation and human resource management practices in cooperative and entrepreneurial HR configurations

Human resource (HR) practices for selection, performance appraisal, performance–compensation linkage and training are found to be less formalized in entrepreneurial HR configurations (exploratory) than in cooperative HR configurations (exploitative). Although less formalization may support more flexibility and improvisation, it was found to have the disadvantage of reducing process transparency, developmental feedback, performance–compensation linkage strength and the amount of training available. These findings are consistent with theories of exploration and exploitation, with their extensions to human resource management and leadership, and the view that HR systems and practice should be varied in light of the organizational processes to which they are being applied.     

Competition and nationally optimum resource allocation under the presence of urban traffic congestion

The present paper compares the market city size and the socially optimal city size in a model which allows for traffic congestion. It establishes that under the assumptions of constant returns to scale and perfect competition for commuter train companies, market forces alone will produce optimality in traffic congestion, in resource allocation for traffic facilities, and in the city size. The notion of optimality in this paper is in the sense of maximizing the welfare of the entire nation, rather than that of the city residents.

Prior knowledge and social networks in the exploitation of entrepreneurial opportunities

In this study we analyze the effects of prior knowledge and social networks on the exploitation of entrepreneurial opportunities. The prior knowledge considered is associated with the successes and failures experienced in the entrepreneurial trajectory and, therefore, derived from the exploitation of prior opportunities. In analyzing social networks, we examine the strength of the relationships between entrepreneurs, managers and entrepreneurial associations. As an explanatory factor of the entrepreneurial process, we also include the influence of the entrepreneurial opportunities recognized. Through a hierarchical regression analysis, we show that the number of potential opportunities recognized, the number of previous opportunities successfully exploited and the strength of entrepreneurial social networks positively influence the number of opportunities developed and exploited.

竞争与合作均衡:企业网络联盟中竞合关系协调的关键

面对复杂的环境和快速多变的市场,企业网络联盟成为企业提升竞争力的重要手段,但联盟关系又有着较高的不稳定性。从企业的角度,以网络联盟形成的利益基础为切入点,找出了联盟不稳定的根源,指出只有在联盟内实现竞争与合作均衡才能维持联盟的动态稳定。可见协调好联盟内竞合关系使之均衡是发挥网络联盟作用的关键,也是研究网络联盟理论的瓶颈问题。文章将从成本、资源、沟通对话、组织演变四个角度来阐述如何实现联盟内竞争与合作的均衡,最终实现网络联盟的目标。     

Leadership and cooperation in growing teams

We study how the growth of teams affects leadership effectiveness and intragroup cooperation. We put experimental participants in two teams. In each team, the members voluntarily contribute to a club good. In one of the two teams, the members observe the contribution of a randomly chosen leader before they decide themselves. Two treatments allow for migration between the teams. In one of them, participants control access to their team with a voting process. By design, participants can achieve the efficient outcome only if they all move into one team. We compare the results with a leaderless setting as well as with four treatments which vary team size exogenously. The results show that high contributions of leaders encourage higher per-capita contributions of their followers which foster migration into their teams. In turn, larger teams experience even more courageous leadership and higher contributions, but the coordination effect diminishes. Nevertheless, the dismissal of potential newcomers in the treatment with voting suggests that team members see a trade-off between team size and contributions. They sacrifice economic benefits from potential entrants to maintain intrateam cooperation.

Technological proximity and the choice of cooperation partner

This paper provides empirical tests of hypotheses of cooperative behavior provided by evolutionary approaches in the resource-based view of the firm. The influences of “technological proximity”, individual incentives to cooperate and managerial tools to the choice of research partner are analyzed. Using German patent data we can show the positive influence of those three determinants. The results of this paper confirm theories dealing with the path-dependency of research activities.      

Programming and Advertising Competition in the Broadcasting Industry

We analyze competition between two private television channels that derive their profits from advertising receipts. These profits are shown to be proportional to total population advertising attendance. The channels play a sequential game in which they first select their profiles (program mixes) and then their advertising ratios . We show that these ratios play the same role as prices in usual horizontal differentiation models. We prove that whenever ads' interruptions are costly for viewers the program mixes of the channels never converge but that the niche strategies are less effective and that the channel "profiles" are closer as advertising aversion becomes stronger.     

Three Modes of Competition in the Marketplace

Competition is often thought of a fairly obvious thing, a rivalry. In a market context the meaning of competition is usually taken to be a rivalry among the sellers. The article seeks to broaden this view by considering other competitive relationships in the marketplace. Using the simplifying assumption that there are only two types of market actors, sellers and consumers, there are three possible types of relationships or interdependencies among these actors in a market. In competitive terms this includes the familiar competition among sellers but there is also the possibility of competition between sellers and consumers, as well as competition among consumers. The article outlines essential characteristics of the three modes. Implications of multi‐mode competition for market performance and welfare are discussed.     

Effect of exploitation and exploration on the innovative as outcomes in entrepreneurial firms

The main aim of this study is to establish the effect of the Exploitation and Exploration; and the influence of these learning flows on the Innovative Outcome (IO). The Innovative Outcome refers to new products, services, processes (or improvements) that the organization has obtained as a result of an innovative process. For this purpose, a relationship model is defined, which is empirically contrasted, and can explains and predicts the cyclical dynamization of learning flows on innovative outcome in knowledge intensive firms. The quantitative test for this model use the data from entrepreneurial firms biotechnology sector. The statistical analysis applies a method based on variance using Partial Least Squares (PLS). Research results confirm the hypotheses, that is, they show a positive dynamic effect between the Exploration and the Innovative as outcomes. In the same vein, they results confirm the presence of the cyclic movement of innovative outcome with the Exploitation.     

Knowledge transfer in acquisitions: Fear of exploitation and contamination

Knowledge transfer plays an important role in the creation of synergies in acquisitions. Acquisitions provide opportunities for learning and are often justified on the basis of the new knowledge made available or created by them. Nevertheless, we do not know enough about the factors that influence knowledge transfer in the context of acquisitions. This paper focuses on the motivation on part of individuals in the acquiring and target companies to share their knowledge and make use of the knowledge of their partner. More specifically, it is hypothesised that the fear of being exploited or contaminated by the other party will have a profound negative effect on the transfer of knowledge in acquisitions. These hypotheses are tested on a sample of acquisitions by Finnish companies in 2001–2004 and they are largely supported by the empirical analyses.
