Other facts

Social Security represents approx. 2/5 of all income for the elderlyAbout 2/3 of elderly Social Security beneficiaries received more than half of their income from OASDIIt is the only source of income for approx. 1/5 of the elderly—Ouch!!!!It is, by far, the primary source of disability insurance in the U.S.

Benefit Eligibility

Eligible for benefits after 10 years of paying into system

Technically, you need 40 quarters of coverageIn 2007, a quarter of coverage is earned for each $1000 of covered earnings

• Amount goes up each year with the wage index

Can earn at most 4 quarters in one calendar yearBut can earn all 4 quarters for the year as soon as you earn 4*$1000

Calculating AIME

Take all of your years of earnings, and index them to age 60 by growth in average wages (AWI)Average the 35 highest yearsConvert to a monthly value to get Average Indexed Monthly Earnings (AIME)

The Normal Retirement Age

“Normal retirement age” (NRA) used to be 65 years. Now it is 65 years + 6 months. It is rising to age 67 for those born in 1960 or later.

Note: There is nothing “normal” about this age, since 80% of workers are retired prior to this!

Also known as “Full Benefit Age” – age at which your benefit is equal to the PIA.The Politics of the NRA

Early Entitlement Age

You can claim SS benefits as early as age 62, but there is an “actuarial reduction” in your benefits to reflect the fact that you will be receiving the benefits for more years

Roughly a 6.67% reduction per year of benefitsAbout 20% lower if retire at 62 instead of 65Same for men and women

Delayed Retirement

If you wait past the normal retirement age to claim benefits, you receive a “Delayed Retirement Credit”

Increases your benefit by 6% (rising to 8% by 2008) for each year of additional work

Spousal BenefitsIf Joe is eligible for SS worker benefits, and Mary is not, then she can receive a spousal benefit that is 50% of his (couple gets 150% of Joe’s PIA)If Joe and Mary are both eligible for benefits, then they receive the higher of:(150% of Joe’s; 150% of Mary’s; Joe’s+Mary’s)

Upon death, survivor benefit = 100% of PIA

Spousal Benefits - 2

Spouse of high income worker gets bigger spousal benefit than spouse of low income workerSystem transfers resources, on average, from single individuals and from two-earner couples to one earner couplesOne earner couples tend to be higher income

Does Social Security Redistribute?Replacement Rates (PIA / AIME) are higher for people with lower AIMEIt is “progressive”See chart on next page …

Replacement Rates = PIA/AIMEBenefit at 65 for those turning 65 in 2005

SS and Redistribution

What is the complication?

Spousal benefits are higher for individuals married to high earnersIndividuals with higher lifetime earnings live longer, on average

Does Social Security Redistribute?

Yes, between generationsMore on this next time!

Yes, at a given point in timeTransfers from today’s taxpayers to today’s elderly (more on this too!)

Yes, if we simply compare replacement rates across the income distribution at age 65But on a lifetime, household basis, the extent of redistribution is much lower (and maybe non-existent)www.ssa.gov
