Using data spanning forty years and tens of thousands of survey respondents, Mark Aguiar and Erik Hurst seek to answer several key questions about leisure inequality: How much has the leisure time of the average American increased or decreased over the last several decades? What increases or decreases in leisure time are seen across groups with different levels of education, and to what extent do educational differences in employment status account for these changes? That is, if workers with relatively little education are less likely to be employed today than twenty years ago, does that explain an increase in their leisure relative to more-educated workers?
