Abstract
The increase in demand for salmon internationally and limited production possibility of that in specific regions of the world increase the concern of lower market competitiveness in this industry. However, as the concentration in the international distribution of salmon has increased simultaneously on the side of other actors of the global value chain, the availability of market imperfection is not obvious anymore which gives the opportunity to test this issue. In this study, we have used the mark-up and Lerner index approach to test the market imperfection in Norwegian salmon industry. The financial data of large enterprises are used for this analysis. The results show that a level in imperfection can be observed in production/processing industry. However, this imperfection is not stable and it can be affected as the cost of production increases which can be affiliated to disease outbreak in sea farm.
