I have heard that spreading corporations among your own cities decreases your income. However I got the corporation that turns coal into aluminum and have been spreading that in my cities and I've noticed that every time I do the amount of profit I get each turn goes UP 1 or two for every city I spread it to. What is going on?
(PS: my plan was to spread the aluminum making corporation among every city in my civ and then stick the one corporation that turn aluminum into hammers in all of my production cities because from what I understand, the aluminum resource stacks meaning that you can use that to add huge amounts of hammers to your production cities. I was then going to go for space race because Monty, Alex, and Ragnor are all really strong militarily and there is no way I can conquer them.
