Three Essays on Agricultural and Food Trade Shocks and Regional Integration
… the first chapter, we investigate the impact of animal diseases on trade of animal-based products. We found that animal disease outbreaks decrease exports by 4% on average per year, amounting to annualized losses of 96 billion of 2019 USD. Trade quantities decline by 8% (51 million tons) on …
