Brexit is a case of unprecedented economic disintegration raising numerous questions around the potential future economic consequences. This thesis aims to identify the post-Brexit challenges that European producers will face in terms of agricultural and food products trade. We start with a review of how economic integration and disintegration are analyzed in the literature, and question whether Brexit is the first episode in a new wave of disintegration in the European Union or an isolated case in the growing integration post-1945. Using basic and structural gravity models, we identify the French sectors that will be most affected, including meat and dairy products.  We analyze all European countries, with a  focus on Ireland and the French Brittany region. In addition to meat, Brittany’s fruit and vegetables are also identified as vulnerable sectors. Irish fish and cereals are sensitive to the potential post-Brexit increase in transport time via the “land-bridge”. We investigate different scenarios on the outcome of trade policy negotiations, not only between the United Kingdom and the European Union, but also between the United Kingdom and third countries. Both European Union countries and the United Kingdom will be less affected if Brexit is followed by the conclusion of a free trade agreement. Finally, this thesis makes an original contribution to the literature on the construction of domestic and regional trade data, but also of data related to modes of transport in international trade.
