The Philippines may be implementing some form of federalism.
Are there economic benefits to federalism? I ask because I observe that both Malaysia and the United States have some kind of federalism, and they are relatively wealthy.
One explanation could be that people can "vote with their feet" in these kinds of federalist countries. Each territory can have different policies on some subjects and people can move to areas that match their preferences. For example, in the United States marijuana is legal in California. People who want to use marijuana can move there and spend their money on marijuana, something which they otherwise might not have done.
In Indonesia, we have a very controversial election. Basically half of the people of Jakarta wants Ahok as governor. The other half think that Ahok is against islam.
It seems that federalism is a good solution for those 2. Let each govern their province as they wish.
And I wonder if this sort of works out in other countries too.
