Nationwide Financial Services Inc. is appealing to annuity buyers who have concerns about future price stability.

Economists have been debating whether inflation or deflation poses a more serious threat to the U.S. economy.

Nationwide Financial, a unit of Nationwide Mutual Insurance Company, Columbus, Ohio, reports that is making a cost-of-living-adjustment (COLA) feature available with a fixed immediate annuity liquidity customization feature.

The COLA can cause income to increase by about 1% to 3% per year, Nationwide says.
