We examine whether the Colombian trade reform can explain any of Colombia's decline in urban poverty between 1984 and 1995. Our approach focuses on short- and medium- run channels through which trade reform could affect poverty. Despite the chronological coincidence of the poverty reduction with...

College attendance and completion in the U.S. are strongly correlated with race and socioeconomic background. Do public postsecondary institutions themselves exacerbate pre-college disparities, or reduce them? We address this question using longitudinal data linking the records of students at...
