At first it would cost a lot since you need at least about 100 of our biggest current day rockets (falcon heavy) to lay the first ring, which would cost 50 billion for launch cost at least. But since the Apollo project costed about 150 Billion in current day dollars, the initial investment would not cripple the economy. Afterwards it would generate unimaginable wealth. It would open up space, make asteroid mining affordable at once, all kinds of rare and precious metals would become abundant. Space based solar power would generate extremely low cost electricity. The electricity could be traded along the ring between various countries, in addition mass transportation along the ring of both cargo and passengers would lead to a huge economic boom.
It would open up several multi trillion dollar industries without a doubt.
