I know that under Despotism my citizens don't produce food to the full capacity of the land they are working on. Once I switch to Monarchy, I'll get more food because now they work the land to full capacity. What happens if I switch to the modern government types? Do I get extra food production? I only know for Republic and Democracy I get extra trade arrows. How about food? I'm very worried about switching to Republic / Democracy from Monarchy in my current game because (1) I have many settlers (2) my people are on the border of happy and unhappy (3) most of my cities only have 1-2 food surplus.
