Maddalena Ronchi is an applied-micro economist whose research interests lie in the areas of labor and personnel economics, with a focus on understanding how labor market frictions affect workers’ career trajectories and corporate behavior. In her work, she explore this topic from two distinct but interconnected angles. First, she is interested in studying the causes and consequences of gender inequalities in labor market outcomes, with an emphasis on the role played by gender attitudes in shaping gender gaps in employment, earnings, and occupational choices. Second, she studies how labor market frictions constraining firms' hiring and wage-setting decisions affect various corporate outcomes, including firms’ ability to attract and retain talent and firms’ growth. To identify the effects of interest, her research primarily uses employer-employee matched data and quasi-experimental designs.
