This year’s Nobel Prize for Economics has been awarded to Claudia Goldin, an American economic historian, for her work on women’s employment and pay. 

Prof Goldin’s research uncovered key drivers behind the gender pay gap, the Royal Swedish Academy of Sciences said. 

She is only the third woman to receive the prize, and the first to not share the award with male colleagues. 

The 77-year-old academic currently teaches labour market history at Harvard University in the US. 

She had “advanced our understanding of women’s labour market outcomes”, the Royal Swedish Academy of Sciences said, pointing to her work examining 200 years of data on the US workforce, showing how and why gender differences in earnings and employment rates changed over time. 

“This year's Laureate in the Economic Sciences, Claudia Goldin, provided the first comprehensive account of women’s earnings and labour market participation through the centuries,” the prize-giving body said in a statement. 

“Her research reveals the causes of change as well as the main sources of the remaining gender gap.” 

Her research found that married women started to work less after the arrival of industrialisation in the 1800s, but their employment picked up again in the 1900s as the service economy grew. 

Higher educational levels for women and the contraceptive pill accelerated change, but the gender pay gap remained. 

While historically that earnings difference between men and women could be blamed on educational choices made at a young age and career choices, Prof Goldin found that the current earnings gap was now largely due to the impact of having children. 

“Claudia Goldin’s discoveries have vast societal implications,” said Randi Hjalmarsson, a member of the committee awarding the prize. 

“She has shown us that the nature of this problem or the source of this underlying gender gap changes throughout history and with the course of development,” she said.
