Different sales channels for different farmers: Local and mainstream marketing of organic fruits and vegetables in Norway
Milford, Anna Birgitte; Lien, Gudbrand; Reed, Matthew (Peer reviewed; Journal article, 2021-08-18)Most food in developed countries, including organic fruits and vegetables, is sold through supply chains run by large wholesalers and supermarket chains. A certain share is sold through local marketing channels such as ... -
Economic performance and efficiency determinants of crop-producing farms in Norway
Alem, Habtamu; Lien, Gudbrand; Hardaker, J. Brian (Journal article; Peer reviewed, 2018)Purpose – The purpose of this paper is to explore the economic performance of Norwegian crop farms using a stochastic frontier analysis.

A multi-attribute decision analysis of pest management strategies for Norwegian crop farmers
Su, Ming; Hardaker, J. Brian; Lien, Gudbrand; Berge, Therese W. (Peer reviewed; Journal article, 2020-02)This study provides a multi-attribute approach to support decisions by Norwegian crop farmers considering adopting innovative crop protection measures. In modelling choice among pest management strategies, we have accounted ... -
Production Function and Farmers' Risk Aversion: A Certainty Equivalent-adjusted Production Function
Lien, Gudbrand; Kumbhakar, Subal Chandra; Mishra, Ashok K. (Peer reviewed; Journal article, 2023-06-08)Faced with risky yields and returns, risk-averse farmers require a premium to take risks. In this paper, we estimate individual farmers’ degrees of risk aversion to adjust for the risk premium in returns and to replace the ... -
Regional differences in technical efficiency and technological gap of Norwegian dairy farms: a stochastic meta-frontier model
Alem, Habtamu; Lien, Gudbrand; Hardaker, J. Brian; Guttormsen, Atle (Journal article; Peer reviewed, 2018-07-30)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 ... -
Risiko og risikohandtering i økologisk jordbruksproduksjon
Flaten, Ola; Lien, Gudbrand; Ebbesvik, Martha; Koesling, Matthias; Valle, Paul Steinar (NILF Rapport;2005-4, Research report, 2005-12)Ofte får gardbrukere erfare at produksjon og inntekt ikke blir som en hadde tenkt seg på forhånd. En gardbruker har aldri full kontroll over de tallrike faktorene som påvirker drifta, og usikre framtidige konsekvenser ... -
