      Kidane, Dejene Gizaw; Myrland, Øystein; Xie, Jinghua (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-26)
      The farmed salmon supply chain in Europe is changing. There is a growing concentration at intermediary levels in the supply chain and more product differentiation in the market. This means that different price determination processes could apply in various product sub-markets. In this study, price transmission relationships in the salmon value chain were investigated at two different product levels. ...

    • Global Seafood Demand Growth Differences across Regions, Income Levels, and Time 

      Kidane, Dejene Gizaw; Brækkan, Eivind Hestvik (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-01)
      We used an index approach to calculate demand growth for seafood in 107 countries from 1984 to 2013. We used the results to calculate aggregate demand growth by income level, regionally, and globally. While seafood production has more than doubled since the mid-1980s, we showed that global demand for seafood has been higher than the global seafood supply. Demand growth for seafood varies across time, ...

Traders having market power could create commodity price stickiness, implying that what goes up does not come down, leading to price increases. The study examines price linkages between principal ...

Among them, one deals with price transmission along the supply chain, and the other two deal with price transmission across spatially distinct markets. The fourth paper measures the effects of demand shifts on the market price equilibrium. <p>Paper 1 investigates price ...
