Agricultural economics is the study of how farmers produce food and other goods, and how these goods are sold in different markets. It is focused on understanding the market forces and economic factors that affect food production and prices. For example, it looks at how policies and subsidies affect the cost of food and how advancements in technology and farming practices help farmers to produce more food in a more efficient way. Agricultural economics also looks at how food prices are influenced by supply and demand, and how different countries and regions trade food with each other.
