Questions & Answers

Q: How do social categories and norms affect labor supply and occupational choice?

Social categories like gender and caste influence the types of jobs individuals aspire to and the effort they put into those jobs. Norms associated with these categories shape behavior and perpetuate inequalities that affect labor supply and occupational choices.

Q: How does an individual's identity impact their preferences for social policies?

An individual's identity, shaped by social categories, norms, and belonging to certain groups, significantly influences their preferences for social policies. Identity frameworks reveal that policy preferences are shaped by factors like class, ethnicity, and nationalism.

Q: How does an evolved Homo economicus framework contribute to understanding inequality?

Including identity and social context in economic models helps to reveal the underlying patterns of inequality. It highlights the impact of social difference, norms, and preferences for inequality on various aspects, such as education, labor market outcomes, social preferences, and political economy.

Q: What are the advantages of including social categories and norms in economic models?

Models incorporating social categories and norms provide more accurate predictions and parsimonious explanations of economic behavior. They allow for a better understanding of complex social interactions and the influence of identity on decision-making. Additionally, these models aid in the formulation of policies that consider the social context and its impact on outcomes.

Summary & Key Takeaways

• Traditional economic models depict individuals as utility-maximizing stick figures, disregarding the importance of social beings and the evolving nature of identity.

• Including social categories, norms, and context in economic models allows for a more accurate representation of human behavior and decision-making.

• Research in areas such as labor supply, social preferences, and political economy illustrates the impact of identity and norms on economic outcomes.

• An evolved Homo economicus framework, embracing social categories and norms, improves prediction accuracy, provides parsimonious explanations, and aids in policy formulation.
