What you’ll learn

  1. A Promise Across DecadesDefine pensions and contrast DB, DC, and public social insurance.Pensions time-shift income. Defined benefit promises a formula; defined contribution specifies deposits; public systems often pool across populations.
  2. Funding, Investing, and PayingExplain contributions, fiduciary investing, and actuarial forecasting.Funded plans invest segregated assets; actuaries price long-term promises; benefits eventually flow to eligible participants.
  3. Eligibility, Risk, and PortabilityMap vesting, risk allocation, and limited guarantee ideas.Rules decide when rights stick and who bears markets, longevity, and inflation — with any public backstops capped by law.

Questions this course answers

What is the key difference between defined-benefit and defined-contribution designs?

DB defines the output formula (with funding obligations); DC defines contributions and leaves the account result variable.

Order the simplified life of money in a funded pension

Funded plans collect, invest, and later pay; market path sits in the middle of the decades-long pipeline.

Match the term to its meaning

Vesting locks claims, longevity is lifespan uncertainty, and pay-as-you-go is an intergenerational funding pattern.

In your own words, why can two people both say they “have a pension” yet face completely different risks?

The label is broad; the design decides who holds market, lifespan, and employer risks.
