I will be doing a Conversation with her, so what should I ask?

Here is part of her Wikipedia page, which perhaps ought to have emphasized economic history more?:

Claudia Goldin...is the Henry Lee Professor of Economics at Harvard University and director of the Development of the American Economy program at the National Bureau of Economic Research. Goldin was the president of the American Economic Association in the 2013–14 academic year. In 1990, she became the first woman to be tenured at the Harvard economics department. Her research includes topics such as female labor force, income inequality, education, and the economic gender gap.

Here are her pieces on scholar.google.com.  And I will take this chance to plug her new, forthcoming book Career and Family: Women's Century-Long Journey Toward Equity.
