Price transmission between energy and fish markets : are oil rates good predictors of tuna prices ? /Guillotreau, Patrice Lantz, F. Nadzon, L. /Rault, Jonathan /Maury, Olivier Cointegration oil and tuna markets regime shift structural breaks Because most food processes are fossil fuel-based, many food markets are more or less connected to the oil market. Fishing technology in the high seas being energy-intensive, higher oil prices should affect the fish markets. This research looks at price transmission between marine diesel oil and a global fishery commodity, frozen skipjack tuna (Katsuwonus pelamis) through a time series analysis combining four different methods to look for possible structural breaks and regime shifts in the relationship (Bai-Perron, Lavielle, Gregory-Hansen, Markov-switching). Our results prove that the long-run equilibrium between both prices is weakening after the turn of the 2010s. Explaining the drivers of change is of great interest for short-term forecast but also to build long-term scenarios where both supply and demand variables are likely to affect tuna markets. 2023 text https://www.documentation.ird.fr/hor/fdi:010086753 fdi:010086753 Guillotreau Patrice, Lantz F., Nadzon L., Rault Jonathan, Maury Olivier.
