Seasonal Harvest Patterns in Multispecies Fisheries

Autor: Frank Asche, Anna M. Birkenbach, Martin D. Smith, Andreea-Laura Cojocaru, Atle G. Guttormsen

Publikováno v: Environmental and Resource Economics

Fishers face multidimensional decisions: when to fish, what species to target, and how much gear to deploy. Most bioeconomic models assume single-species fisheries with perfectly elastic demand and focus on inter-seasonal dynamics. In real-world fish

Production risk of pangas (Pangasius hypophthalmus) fish farming

Autor: Kristin H. Roll, Atle G. Guttormsen, Akhtaruzzaman Khan

Publikováno v: Aquaculture Economics & Management. 22:192-208

Pangas is a relatively new and fast-growing fish species that has great potential for production and export growth in Bangladesh. However, production variability exists from farm to farm and location to location, which indicates that production risk

Regional differences in technical efficiency and technological gap of Norwegian dairy farms: a stochastic meta-frontier model

Autor: Habtamu Alem, Gudbrand Lien, J. Brian Hardaker, Atle G. Guttormsen

Publikováno v: Applied Economics

This paper compares technical efficiencies (TEs) and technological gap ratios (TGRs) for dairy farms in regions of Norway, accounting for differences in working environments. We used the state-of-the-art stochastic meta-frontier approach to estimate
