• Competitive Balance When Winning Breeds Winners 

      Clark, Derek John; Nilssen, Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-01)
      In contest settings, heterogeneity between contestants generally leads to low effort provision, and many instruments have been suggested to restore competitive balance. We suggest that heterogeneity may evolve depending upon the outcome of previous contests. Restoring competitive balance in this setting is challenging, and we consider the choice faced by a principal who can distribute a prize fund ...
    • Competitive balance: Information disclosure and discrimination in an asymmetric contest 

      Clark, Derek John; Kundu, Tapas (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-14)
      We study a design problem for an effort-maximizing principal in a two-player contest with two dimensions of asymmetry. Players have different skill levels and an information gap exists, as only one player knows the skill difference. The principal has two policy instruments to redress the lack of competitive balance due to asymmetry; she can commit to an information-disclosing mechanism, and she can ...
    • Creating balance in dynamic competitions 

      Clark, Derek John; Nilssen, Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-02)
      We consider incentives for organizing competitions in multiple rounds, focusing on situations where there is heterogeneity among the contestants ex ante, which discourages effort in a single contest. Heterogeneity evolves across rounds depending upon the outcomes of previous rounds. We present conditions under which balance in such a competition can be created, by determining the number of rounds ...
    • Endogenous technology sharing in r&d intensive industries 

      Sand, Jan Yngve; Clark, Derek John (Journal article; Tidsskriftartikkel; Peer reviewed, 2010-01-11)
      This paper analyses endogenous formation of technology sharing coalitions with asymmetric firms. Coalition partners produce complementary technology advancements, although firms do not co-operate on R&D investment level or in the product market. The equilibrium coalition outcome is either between the two most efficient firms, or a coalition with all three firms. The two-firm coalition is the preferred ...
    • Gaining advantage by winning contests 

      Clark, Derek John; Nilssen, Tore; Sand, Jan Yngve (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-20)
      We consider a principal who faces many identical competitors, and who can distribute a prize fund over two consecutive contests. The winner of contest one gains an advantage in contest two where his effort is more productive than all rivals. We identify a tipping point for the productivity parameter, below which it is optimal for an effort-maximizing principal to place the whole prize in the second ...
    • Group bargaining in supply chains 

      Clark, Derek John; Pereau, Jean-Christophe (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-10)
      We consider a vertical supply chain in which a monopoly retailer produces a good by assembling a number of essential components each of which is owned by a monopoly. Rather than making the common assumption that the component price is set in the same way for each owner, we investigate the possibility that the retailer may profit by bargaining with some owners in a group, whilst others set their ...
    • Partial information disclosure in a contest 

      Clark, Derek John; Kundu, Tapas (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-18)
      Zhang and Zhou (2016) use the concept of Bayesian persuasion due to Kamenica and Gentzkow (2011) to analyze information disclosure in a contest with one-sided asymmetric information. They show that an effort-maximizing designer can manipulate information disclosure to increase expected efforts in the contest, based upon active contest participation by all types of the informed player. We allow some ...
    • Relationships between fares, trip length and market competition 

      Clark, Derek John; Jørgensen, Finn; Mathisen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2011-04)
      This paper analyses equilibrium fares that arise from Collusion, Cournot, Stackelberg, Bertrand and Sequential Price Competition when two profit maximising transport firms produce symmetrically differentiable services and have identical costs. Special focus is placed on how different equilibrium fares are linked to trip length. Higher operator costs and higher demand from the authorities regarding ...
    • Salience in a simple transport market 

      Clark, Derek John; Mathisen, Terje Andreas (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-04)
      Psychologists have long since recognized that consumers have limited cognitive ability, and that this prevents them from weighing up all product attributes when making a choice. More recently, a new framework for consumer choice has been developed which takes account of this, by assuming that consumers are drawn to salient features of a product. We apply the framework of salient thinking to a simple ...
    • The EU block exemption and horizontal R&D agreements 

      Clark, Derek John; Michalsen, Anita; Olsen, Leif Roger (Journal article; Tidsskriftartikkel, 2020-09-24)
      We analyze the effect of the European Union Competition Authority’s block exemption towards R&D cooperatives in a horizontal market structure, valid as long as the combined product market share is not too large. Two less efficient firms attempt to catch up with a technological leader, and may use the safe harbour provided by the legislation. We consider when the incentives of the R&D-performing firms ...
    • Vertical integration through Rubinstein bargaining 

      Clark, Derek John; Pereau, Jean Christophe (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      We consider a vertical structure in which an upstream manufacturer bargains with a downstream retailer over the price of an intermediate good. In an alternating offers framework, we show that when the managers of the firms can choose their response time in the negotiation that the solution conforms either to the non-intergrated or fully integrated structure from standard models of successive monopoly.
