How Career Gaps Can Reshape Retirement Income

Why Job Instability Makes Early Investing More Important

Retirement plans often assume a career that unfolds in a straight line: earnings rise, contributions continue, and investments compound until retirement. Real careers are less predictable. Layoffs, illness, industry changes, and difficult job searches can interrupt that process. The financial damage can extend well beyond the months without a paycheque.

A new study by Leanne Nam, accepted by the Journal of Monetary Economics, examines how differences in employment stability shape lifetime earnings, wealth, and pension security.¹ Its central finding concerns Social Security design, but it also offers a practical lesson: stable earning periods are valuable opportunities to build assets before future disruptions limit the ability to invest.

That does not mean investing every available dollar. A resilient retirement plan needs both long-term investments and accessible savings that help protect those investments when income disappears.

How Career Instability Compounds Retirement Risk

Nam develops a life-cycle model calibrated to the U.S. economy. Workers differ in their likelihood of losing jobs and make decisions about saving, developing skills, and retiring. This lets the analysis examine how employment risk accumulates across a working lifetime.

The mechanism reaches beyond missed wages. Job displacement can push workers into lower-paying positions and less stable employment. They may invest less in skills because the expected payoff becomes weaker. Lower earnings then restrict savings, leaving fewer assets available to support retirement.

Public pension benefits can carry part of that disadvantage into old age. The Social Security Administration explains that benefits use a worker’s highest 35 years of earnings. Having fewer than 35 earning years introduces zeros into the calculation. A career gap does not automatically reduce benefits for everyone, but prolonged interruptions or persistently lower earnings can matter.

This creates a planning problem: the workers most exposed to employment disruption may also have the least capacity to repair its consequences. A retirement projection based only on current salary and uninterrupted contributions can conceal that vulnerability.

What the Pension Study Actually Finds

The paper finds that a substantially more progressive pension system improves welfare in its model. Progressivity means replacing a larger share of earnings for lower-income workers, providing stronger protection against weak lifetime earnings.

The preferred configuration combines a benefit schedule approaching a benefit floor with removal of the Social Security earnings cap. Broadening the taxable earnings base allows the model’s budget-balancing payroll tax rate to fall even as retirement protection becomes more progressive.

The 0.94% figure is a consumption-equivalent welfare gain, a way of expressing the value of greater security and changed outcomes. It is not an investment return or a promised increase in everyone’s pension. The paper also identifies costs: greater progressivity weakens incentives to develop skills and encourages earlier retirement among some lower-income workers. Within the model, the insurance benefits outweigh those costs.

These are modelled results under specified assumptions, including a partial-equilibrium framework. They do not establish the full economy-wide effects of reform or predict legislation. Nor does the study test a particular portfolio strategy.

Invest While You Can, Without Assuming You Always Can

The investing implication is straightforward: future contributions are uncertain. Waiting for a higher salary or a quieter stage of life assumes those opportunities will arrive. Investing an affordable amount during stable periods gives existing assets more time to grow before contributions might need to pause.

Consider a hypothetical $5,000 invested for 30 years at a constant 5% annual return. It would grow to approximately $21,610. The same amount invested with 20 years remaining would reach roughly $13,266. These figures exclude fees, taxes, and inflation, and the return is an illustration rather than a forecast. They show why postponing contributions can have lasting consequences.

A workable approach is a baseline contribution that fits normal cash flow, with additional deposits during stronger earning periods. That might mean directing part of a bonus or pay increase toward investments before household spending expands. Securities.io’s discussion of choosing an investment style provides useful context for matching a strategy to financial circumstances.

Flexibility matters. Pausing contributions during unemployment is different from abandoning a retirement plan. Assets already accumulated may remain invested, provided living expenses can be covered elsewhere. The goal is a plan that survives interruptions.

Why Emergency Savings Protect Long-Term Investments

Cash reserves can look unproductive beside a rising stock market. Their purpose becomes clearer when wages stop. A reserve can reduce the need to borrow or sell investments at an inconvenient time, preserving the ability to remain invested.

The Federal Reserve’s 2026 report on household savings found that 55% of U.S. adults had set aside three months of expenses in 2025. Thirty percent could not cover three months through savings, borrowing, or selling assets. Those figures illustrate how quickly an employment shock can become a financial emergency.

The right reserve depends on essential expenses, income reliability, and likely job-search duration. Two incomes offer less protection when both earners depend on the same industry. Securities.io’s timeless financial rules discuss emergency savings alongside broader investing principles.

• Keep money needed during an income interruption readily accessible.
• Build long-term investments around contributions that remain affordable.
• Reassess savings targets when employment risk or household obligations change.

Your Career Belongs in Your Portfolio Risk Assessment

A further implication is that investment risk should be evaluated alongside employment risk. Someone working in a cyclical industry may face layoffs during the same downturn that reduces portfolio values. Owning substantial employer stock can intensify that exposure: salary and investments depend on one business.

Diversification cannot prevent unemployment, but it can reduce dependence on the employer or sector already supporting household income. Retirement projections can also test a contribution pause or a lower salary after re-employment, revealing whether the plan relies too heavily on continuous earnings.

Skill development remains relevant too. Training, credentials, and professional networks may improve employability. The paper’s treatment of human capital reinforces a broader point: protecting future earning capacity and accumulating financial assets are complementary parts of retirement preparation.

Prudential and the Market for Retirement Income Protection

Building assets is only part of retirement security. Turning those assets into dependable income creates demand for financial businesses that develop retirement products. Prudential Financial (PRU ) offers investors exposure to that market through insurance, annuities, and investment management.

In December 2025, Prudential announced FlexGuard 2.0, an updated registered index-linked annuity with expanded allocation choices and protection features. Such products illustrate innovation in managing retirement uncertainty, although contractual protections have limits and early withdrawals can carry charges.

For shareholders, the relevant questions include product demand, profitability, and the insurer’s ability to manage long-term obligations. Buying Prudential shares does not provide the contractual protections offered by its annuities, and the study does not establish that its proposed reforms would benefit the company.

The broader lesson is to treat reliable earnings as an opportunity to prepare for less reliable periods. Invest what is sustainable, preserve access to emergency cash, and account for career interruptions before they occur. A retirement plan becomes stronger when it allows for the possibility that tomorrow’s ability to save will differ from today’s.
