Thesis Company competitiveness and vineyard dieback

The thesis will focus on the economic impact of vineyard dieback for companies in the wine industry. For more than ten years, a significant erosion in yields has been observed, along with a very substantial rise in vine mortality which has undermined the productivity of French vineyards. Within a challenging economic context, the drop in yields has a direct impact on the profitability of wine-making companies and on their positioning in the wine market. Drawing on work in the field of agricultural economics, the objective of the thesis will be to analyze the impact of vineyard dieback on wine-making companies in different production contexts and in the long term through the study of several components.
