Dr Humberto Barreto earned his PhD from the University of North Carolina, Chapel Hill in 1985 with a specialization in the history of economic thought. In his teaching and writing, Barreto applies a pedagogical philosophy that eschews formalism and abstraction in favor of concrete problems and hands-on learning. He shows students how economists think, manipulate models, and use data. Barreto has previously been a Fulbright Scholar in the Dominican Republic, has won several teaching awards, and has given workshops all over the world on how to improve the teaching of economics and econometrics.
