Are political and economic freedom closely tied?
The is a certain degree of association in history between political and economic liberty, and it is an association, not a causation.
And it is complex.
There is a very real set of tensions between markets and freedom and politics and systems and biology.
It seems clear to me that free markets are now the single greatest threat to individual and political freedom. This certainly has not been the case through most of history, but is true now that technology is at the point of allowing us to automate any process.
Full automation is anathema to market value.
Markets demand poverty (unmet demand) to work – full automation can meet all reasonable demand.
The major reason for poverty or want in the world today is the incentive sets present in markets.
So it is a a very complex situation, and no – economic and political freedom are not at all tied, not any more.
