Costing billions of dollars annually, international trade in agricultural products is impactful and influenced by several factors, including climate change, food policy, and government legislation. The third edition of Agricultural Policy, Agribusiness, and Rent-Seeking Behaviour provides comprehensive economic analyses of the policies that affect agriculture and agribusiness in Canada and the United States. Looking at current agricultural policies, the third edition includes new chapters on food pyramids, climate change, and GMOs, while also highlighting the effect of international policies on Canadian trade, including the problematic US ethanol policy. The new edition addresses current issues, including how the COVID-19 pandemic has negatively affected agricultural value chains and played a hand in the ongoing growth in opioid use. Including a number of key findings, and discussing current debates on topics including foreign ownership of Canadian farmland, Agricultural Policy, Agribusiness, and Rent-Seeking Behaviour will appeal to students in agricultural economics and policy, as well as policymakers, agricultural firms, energy companies, and readers wishing to reduce their nation’s carbon footprint.
