A quarter of U.S. families feel they are under economic stress due to the aftershock of the Great Recession and most do not expect their wages to increase in the next year, according to a new Federal Reserve study released on Thursday.

In its first large-scale study of household finances, the U.S. central bank uncovered lingering effects of the sharpest economic downturn since the Great Depression, with 42 percent of respondents saying they had delayed major purchases and 18 percent saying they put off a major life decision, including buying a home or getting married, due to the crisis.
