The impact of agricultural policy evolution on long‐run grain market projection

Abstract Long‐run projections are crucial for climate change policies, food security, and agricultural productivity, yet these projections often overlook recently identified patterns in how trade policies and domestic support evolve as countries develop. The grain market projections over 50 or 100 years presented here take these policy patterns into account, as well as the risks of more significant trade policy disruptions. The results demonstrate that different assumptions about economic development can have far‐reaching effects on the market context, greenhouse gas emissions, and grain prices.
