Goldin (2023): Two Centuries of Data on Why Women Still Earn Less

The Question That Wouldn’t Go Away

Women now earn university degrees at higher rates than men. They enter the workforce in nearly equal numbers. They are lawyers, doctors, executives, engineers. Yet in every country on earth, women earn less than men — in the United States, about 13% less on average.

Why? The obvious answer — discrimination — is part of the story but far from the whole story. If employers were simply paying women less for identical work, competition would eliminate the gap: firms that hired underpriced women would outperform those that didn’t. Something deeper and more structural must be at work.

Claudia Goldin spent her career assembling the answer. By mining 200 years of U.S. data — census records, tax files, surveys, institutional archives — she traced the entire history of women’s economic participation and identified the forces that have shaped, closed, widened, and stubbornly maintained the gender gap at each stage. Her story is not the one most people expect.

The U-Shaped Curve: A Surprise in the Archives

The conventional narrative says women’s work has been a story of steady progress — from housewives to workers, from exclusion to inclusion, climbing ever upward.

Goldin found the opposite. Female labor force participation over the past 200 years follows a U-shaped curve:

• Agricultural era (early 1800s): Women worked extensively — on farms, in family businesses, in cottage industries. Their labor was economically essential, even if it wasn’t always recorded
• Industrialization (mid-1800s to early 1900s): As production moved from homes to factories, women’s labor force participation declined. Factory work was physically demanding, socially stigmatized for married women, and increasingly separated from the home. As male wages rose, families could “afford” to have wives stay home. Social norms hardened: a working wife signaled that her husband couldn’t provide
• Service economy (early 1900s onward): As the economy shifted toward clerical, administrative, and professional work, women’s participation began to rise again. Office work was cleaner, safer, and more compatible with social expectations. Education expanded. The curve turned upward

This U-shape was invisible until Goldin dug into the archives. Previous researchers had massively undercounted women’s work in the nineteenth century because census takers didn’t record unpaid farm labor, family business work, or piecework done at home. Goldin showed that women at the end of the 1890s were employed at nearly three times the rate that census data suggested. The “rise” of women’s work in the twentieth century was partly real and partly a measurement artifact — women had always worked, but the nature and visibility of their work changed.

The Quiet Revolution: Expectations, Education, and the Pill

Goldin identified a critical turning point in the 1970s — what she called the quiet revolution. Before this point, women’s participation was rising, but women still planned their lives around marriage and children. Career was secondary. After this point, women began to form their identities around careers, not just jobs.

What changed? Three forces converged:

The contraceptive pill

Goldin (with Lawrence Katz) showed that access to the birth control pill was transformative. Using the fact that different U.S. states legalized the pill for young unmarried women at different times, she demonstrated that the pill:

• Allowed women to delay marriage and childbirth — giving them time to invest in education and establish careers
• Changed career choices: the proportion of women studying law, medicine, and business exploded. Between 1970 and 1980, women in law schools more than tripled; women in business schools increased tenfold
• Changed expectations: women who had access to the pill when young planned their entire lives differently — they expected careers, not just jobs

Rising education

Each generation of women was better educated than the last. But Goldin showed a crucial pattern: women’s educational investments often lagged behind their opportunities. Women in the 1950s invested less in education than they should have, because they expected to follow their mothers’ patterns (marry young, leave the workforce). By the time they realized the world had changed, it was too late to go back to school. Expectations matter — and outdated expectations are costly.

Shifting social norms

The women’s rights movement, changing attitudes toward working mothers, and the visible success of pioneering women all contributed. But Goldin emphasized that norms changed slowly — much more slowly than economic conditions. The lag between opportunity and norm adjustment is a recurring theme in her work.

The Motherhood Penalty: Where the Gap Really Opens

Here is Goldin’s most striking finding: the gender pay gap today is primarily a motherhood gap.

At the start of their careers, men and women with the same education, in the same occupation, earn nearly the same. The gap is small and shrinking. But when the first child arrives, everything changes:

• Women’s earnings drop sharply and recover slowly — if they recover at all
• Men’s earnings are unaffected by fatherhood — they may even increase (the “fatherhood premium”)
• In a 15-year study of University of Chicago MBA graduates, Goldin found that men and women started at similar salaries. Fifteen years later, women with children earned dramatically less — not because they were in different occupations, but because they had reduced hours, taken career breaks, or shifted to less demanding (and less lucrative) roles

The motherhood penalty is not about employer discrimination in the narrow sense. It’s about how families respond to the arrival of children — and how the labor market rewards that response.

Greedy Jobs: The Structural Root of the Gap

Goldin’s deepest insight is the concept of greedy jobs — positions that disproportionately reward workers who are available at all hours, travel on short notice, never turn off their phones, and prioritize work above everything else.

• A corporate lawyer who bills 2,500 hours a year earns far more than twice what a lawyer billing 1,250 hours earns — the premium for total availability is enormous
• A management consultant who can fly to a client on Sunday night commands a premium over one who can’t
• A finance executive who answers emails at midnight gets promoted faster than one who doesn’t

These greedy jobs don’t explicitly discriminate by gender. But when a couple has children, someone must be on call for the family — sick children, school pickups, bedtime routines. In most couples, it’s the woman who adjusts. She takes the flexible job, the part-time role, the position with predictable hours. He takes the greedy job.

This isn’t irrational — it’s financially logical. If the greedy job pays a premium for total availability, the family maximizes income by having one spouse commit fully. Since the husband is often already earning slightly more (perhaps because he’s slightly older or started full-time earlier), it makes sense for him to be the one who leans in. But this individually rational choice, repeated across millions of couples, produces the gender pay gap.

The implication is profound: the pay gap would shrink dramatically if greedy jobs didn’t exist — if companies rewarded output rather than face time, if workers could share roles and work flexibly without penalty, if being a devoted parent didn’t require sacrificing career advancement.

Why It Took 200 Years of Data

Goldin’s methodological innovation was insisting that you can’t understand the present without understanding the past. Each generation’s choices are shaped by the previous generation’s experiences and expectations:

• Women in the 1950s planned their lives based on their mothers’ experiences in the 1930s — and were caught off guard when the world changed
• Women in the 1970s had access to the pill and new career opportunities — but their expectations had been formed in a world without these tools
• Women today have equal education and legal rights — but work in labor markets whose structures were designed around male breadwinners with stay-at-home wives

Only by tracing the full arc — from farm to factory to office to Zoom call — could Goldin identify which forces were transient and which were structural, which barriers had fallen and which persisted in new forms.

Her 2023 Nobel Prize was awarded “for having advanced our understanding of women’s labour market outcomes.” She was the first woman to win the economics Nobel solo, and only the third woman ever to receive it (after Elinor Ostrom in 2009 and Esther Duflo in 2019).

Explain It to a Child

Imagine two kids start the same race at the same time, running at the same speed. For the first part of the race, they’re neck and neck. Then one kid has to stop and tie their little brother’s shoes, help him get a drink, and carry him for a while. When they start running again, they’re way behind — not because they’re slower, but because they had to take care of someone. That’s what happens to many women’s careers when they have children. Goldin spent her whole career studying this by looking at records going back 200 years. She found that the pay difference between men and women isn’t mostly about bosses paying women less for the same work — it’s about the fact that certain jobs pay a LOT extra for being available 24/7, and when a family has kids, it’s usually the mom who steps back from those demanding jobs to take care of the family. She also found that when the birth control pill was invented, it changed everything — women could plan when to have kids, so they could invest in long educations and start careers first. Her big idea for fixing the remaining gap? Change the jobs, not the women — make workplaces more flexible so that being a good parent doesn’t mean giving up career success.
