Some notes on definition, from top to bottom (not including
Knowledge Economy)
Deregulated is considered to be the default civic for developing nations. As its name implies, there are no regulations, but also not too much economic production in the private sector. It can be a profitable civic unless your cities get bought up by foreign investment; at that point you can switch.
Communist refers to the Sino-Soviet state-socialist model, not theoretical Anarchistic Marxism. This is a good civic for dragging a backwater agrarian civilization into industrialism by the balls, although it isn't good for making money in the long run.
Corporatist is based on the modern economics of most Asian Industrial powers like China and Japan. The state here does not own production as in a communist state; rather, it encourages private enterprise as long as it's in a way that benefits the state, attracting investment and channelling funds into infrastructure.
Military-Industrial economies are those where all of a country's infrastructure is utilized primarily for the production of military units. Car factories only make tanks, planes, etc, civilian consumption of tin, gas, and even food, may be rationed, and ultimately, most money spent in the country doesn't end-up there.
Grass-roots economies are defined as being a combination of environmentalism, and an attempt to recreate the classical model of private enterprise. The government does not own production; rather, it proactively safeguards the rights of its citizens to own businesses, and gives them preferential treatment over multinational investment.
