Karl is a Postdoctoral Research Associate at the Yale School of
Management, working with Seth Zimmerman and The Broad Center. He
earned his PhD in Economics at Princeton in 2024 under Christopher’s
supervision. His research is in labor and education economics,
focused on the role of career and education choices in explaining
earnings inequality — including how workers respond to adverse
shocks by returning to school later in life, drawing on
administrative panel data and a dynamic model of education-and-work
tradeoffs around the Great Recession.
