      Hausken, Kjell (Journal article; Peer reviewed, 2012-06)
      A sequential Colonel Blotto and rent seeking game with fixed and variable resources is analyzed. With fixed resources, which is the assumption in Colonel Blotto games, we show for the common ratio form contest success ...
    • Policy Makers, the International Community and the Population in the Prevention and Treatment of Diseases: Case Study on HIV/AIDS 

      Hausken, Kjell; Ncube, Mthuli (Journal article; Peer reviewed, 2017-01)
      A four-period game is developed between a policy maker, the international community, and the population. This research supplements, through implementing strategic interaction, earlier research analyzing "one player at a ...
    • Production and conflict models versus rent-seeking models 

      Hausken, Kjell (Journal article; Peer reviewed, 2005-04)
      Aproduction and conflict (P&C) model and a rent-seeking (RS) model are compared for one group, two groups and K groups. Adding a newagent enlarges the pie in the P&C model, but causes the fixed size pie to be allocated ...
    • Production versus safety in a risky competitive industry 

      Hausken, Kjell (Peer reviewed; Journal article, 2012)
      Each of two firms has a resource that can be converted into safety versus productive investment in the first stage, with Bertrand competition on price in the second stage of a two-stage game. The firms produce differentiated ...
    • Production, safety, exchange, and risk 

      Hausken, Kjell (Journal article; Peer reviewed, 2011)
      Two agents convert resources into safety investment and production while exchanging goods voluntarily. Safety investment ensures reduction of costly risk. High unit cost of safety effort reduces both productive effort ...
    • Production, safety, fighting, and risk 

      Hausken, Kjell (Journal article; Peer reviewed, 2011)
      Two agents make a trade off between production and safety investment, fighting for joint production. Ceteris paribus, if agent 1 has a higher unit cost of production, lower emphasis on safety causes more fighting and higher ...
    • Protection vs. separation in parallel non-homogeneous systems 

      Hausken, Kjell; Levitin, Gregory (Journal article; Peer reviewed, 2009)
      The article considers strategic defense and attack of a system consisting of N functionally identical parallel elements of n types distinguished by element’s performance. The elements can be separated in order to reduce ...
    • Reputation, incomplete information, and differences in patience in repeated games with multiple equilibria 

      Hausken, Kjell (Journal article; Peer reviewed, 2007)
      A game with multiple equilibria and incomplete information, which allows for reputation building, is repeated infinitely many times. Increasing differences in patience contribute to a greater likelihood of cooperation. As ...
    • Risk limits, conflict, and equilibrium selection in games with multiple equilibria 

      Hausken, Kjell (Journal article; Peer reviewed, 2009)
      A risk limit conflict measure is developed as the product of the two players’ maximum probabilities of being recalcitrant when pursuing a preferred equilibrium. Although the justification for it is different, the measure ...
    • Risk, price, and reimbursement 

      Hausken, Kjell (Journal article; Peer reviewed, 2010)
      The article offers five hypotheses for the inverse relationship between risk and price in terms of first and second derivatives, establishing ranges of convexity, linearity, concavity. Negative price means reimbursement. ...
    • Risk, production and conflict when utilities are as if certain 

      Hausken, Kjell (Journal article; Peer reviewed, 2010)
