This paper discusses population aging, increased participation of seniors in the labor force in the United States (and reasons for this), and how these trends are making the struggles of older workers in the labor market increasingly relevant. Evidence examining whether age discrimination is a...

This chapter surveys the theoretical literature on statistical discrimination and affirmative action. This literature suggests different explanations for the existence and persistence of group inequality. This survey highlights such differences and describes in these contexts the effects of...

This article reviews the existing field experimentation literature on the prevalence of discrimination, the consequences of such discrimination, and possible approaches to undermine it. We highlight key gaps in the literature and ripe opportunities for future field work. Section 1 reviews the...

Supply-side Social Security reforms intended to increase employment and delay benefit claiming among older individuals may be frustrated by age discrimination. We test for policy complementarities between these reforms and demand-side efforts to deter age discrimination, specifically studying...

This paper provides a simple conceptual framework that captures how different perceptions, attitudes, and biases about immigrants or minorities can shape preferences for redistribution. Through the lens of this framework, we review the empirical literature on the effects of racial diversity and...

This chapter reviews the data and literature on gender, race and ethnicity differences in research funding in the United States and Europe. The gender gap in research funding has closed at the National Science Foundation and National Institutes of Health in the United States and substantially...

We provide evidence from a field experiment in all 50 states on age discrimination in hiring for retail sales jobs. We relate measured age discrimination - the difference in callback rates between old and young applicants - to state variation in anti-discrimination laws protecting older workers....

Racial affirmative action policies are widespread in college admissions. Yet, evidence on their effects before college is limited. Using four data sets, we study a U.S. Supreme Court ruling that reinstated affirmative action in three states. Using nationwide SAT data for...

This chapter surveys the contributions of laboratory experiments to labor economics. We begin with a discussion of methodological issues: why (and when) is a lab experiment the best approach; how do laboratory experiments compare to field experiments; and what are the main design issues? We then...

The Supreme Court has held repeatedly that race-based preferences in public university admissions are constitutional. But debates over the wisdom of affirmative action continue. Opponents of these policies argue that preferences are detrimental to minority students -- that by placing these...
