Understanding the exact connection between inequality and justice is important because justice is classically regarded as the first line of defense against self-interest and inequality. Absent a strong and clear link between inequality and justice, the sense of justice would not awaken to exert its moral suasion, no matter how...

Migration and stratification are increasingly intertwined. One day soon it will be impossible to understand one without the other. Both focus on life chances. Stratification is about differential life chances – who gets what and why – and migration is about improving life chances – getting more of the good...

This paper proposes a new unified theory of sociobehavioral forces. The goal of the new theory is to integrate theories describing five sociobehavioral processes – comparison (including justice and self-esteem), status, power, identity, and happiness – bringing under a single theoretical umbrella diverse mechanisms together with their effects across disparate...
