In the manual, it's stated that switching to a more advanced government provides an economic bonus. For a Republic it's 15%, for a Democracy 25% and for a Federation 50%
But when I go hit the "Government" tab on the stats and charts menu, I'm told that my Star Democracy is providing an economic bonus of 50, an industrial bonus of 50 and a research bonus of 50.
Does anyone know which (if any) of these is true? And if an economic bonus is provided, does it affect all income including taxes, tourism, trade, gifts from other races, windfalls from selling "Juice", etc?
