Usually subassemblies are build near the main assembly to reduce cost, inventory, and overhead, unless the transportation cost is significantly lower than the production labor cost, this rule applies.
R&D on the other hand, tends to be more skill specific and that's where companies build their research center near existing tech hubs, universities, or former research center for similar industries (i.e. how most high tech hub in California are near former military air base). Sometimes you see government give incentives to move a tech center to a particular location, but that's usually low end tech center for testing, process, rather than engine design or top secret projects.

That depends on who you give it to. Common consensus is that the lower income the recipients, the higher the multiplier because they won't just stash it away but they need to spend it due to financial hardship.
