Field of Study Choices & Mobility Trajectories Sigal Alon Tel-Aviv University
Conference on Social Mobility, June 14-15, 2017
The Stratifying Role of FOS • FOS: the most important determinant of future earnings
• Arcidiacono 2004; Roksa and Levey 2010; Altonji, Blom and Meghir 2012; Kim, Tamborini, and Sakamoto 2015
• FOS choices:
• Determinants of intra- and intergenerational mobility • One of the factors perpetuating inequality
Key Questions • Segregation in choices
• Are there systematic differences between individuals’ choices?
• Collective logic
• Are there systematic differences in the operation of specific decisionmaking rules?
• Mobility Trajectories
• What are the academic and economic implications of systematic differences decision making?

FOS choices & Mobility Trajectories • Studying the college major choice set
• Differences b/w groups in decision making process • The role played by the individual’s choices in the fanning out of life trajectories • The roots of gender, racial/ethnic, and class-based inequality • The way to reduce economic inequality and enhance socioeconomic mobility
