Two studies released Tuesday show wide geographic variation in Obamacare price increases seen this year, and in those proposed for next year. Although there are plenty of double-digit prices being proposed, that isn’t the case everywhere. The studies underscore that the amount people pay for their Obamacare plans is often strongly related to where they live. They also show how much lower the price increases can be for a customer who switches plans within the same Obamacare “tier.” And one of the studies, by the Avalere Health consultancy, also backs the widespread belief that prices for 2017 likely will rise faster than they did this year.
