Peter Gosselin: Exchange Competition Cuts Health Insurance Costs:
Competition among insurers offering coverage through federal exchanges established under the Affordable Care Act is driving down the premiums charged in the new marketplaces by as much as one third…. The larger the number of insurers operating in a given market, the lower the price of coverage. The pattern appears to hold no matter what the age of insurance enrollees or which “metal” level of coverage they choose…. “Bronze” plans cover 60 percent of expected medical costs and so on, up to “platinum” at 90 percent.
