• A Bellman approach to periodic optimization problems 

      Kvamsdal, Sturla F.; Maroto, José M.; Morán, Manuel; Sandal, Leif K. (Discussion paper;19/16, Working paper, 2016-11-30)
      We consider an infinite horizon optimization problem with arbitrary but finite periodicity in discrete time. The problem can be formulated as a fix-point problem for a contraction operator, and we provide a solution scheme ...
    • A bridge between continuous and discrete-time bioeconomic models: Seasonality in fisheries 

      Kvamsdal, Sturla F.; Maroto, José M.; Morán, Manuel; Sandal, Leif K. (Discussion paper;20/16, Working paper, 2016-11-30)
      We develop a discretization method for continuous-time bioeconomic models. Based on this method, we develop a discrete-time bioeconomic model to analyze seasonality in fisheries. The discretization method consists of three ...
    • A contraction approach to periodic optimization problems 

      Sandal, Leif K.; Kvamsdal, Sturla F.; Maroto, José M.; Morán, Manuel (Working paper, 2017-11)
      Consider an infinite horizon, multi-dimensional optimization problem with arbitrary but finite periodicity in discrete time. The problem can be posed as a set of coupled equations. We show that the problem is a special ...
    • Building conditions in Norwegian local governments : trends and determinants 

      Hopland, Arnt O.; Kvamsdal, Sturla F. (Working paper;2017:13, Working paper, 2017-10)
      In light of evidence of low levels of maintenance of public buildings, we investigate trends and determinants of public building conditions in Norwegian local governments. On average, the condition of Norwegian local public ...
    • Concerns among local government facility managers 

      Hopland, Arnt Ove; Kvamsdal, Sturla F. (Working paper;2016:9, Working paper, 2016-12)
      Purpose: To investigate which concerns are most important for local government facility managers in Norway. Design: We analyze a survey dataset covering about 2/3 of all Norwegian local governments, using descriptive ...
    • Greed is good: from super-harvest to recovery in a stochastic predator-prey system 

      Ni, Yuanming; Sandal, Leif K.; Kvamsdal, Sturla F.; Poudel, Diwakar (Discussion paper;5/19, Working paper, 2019-09-04)
      This paper demonstrates a predator-prey system of cod and capelin that confronts a possible scenario of prey extinction under the first-best policy in a stochastic world. We discover a novel ‘super-harvest’ phenomenon that ...
