Applying Pure Mathematics: IMPA and the Entanglements of Mathematical Economics in Brazil
研究了巴西纯数学与应用数学研究所（IMPA）中数理经济学群体的形成，追溯其自1950年代起如何使经济学成为应用数学的替代方向，并探讨1980年设立的数理经济学研究生项目如何与巴西重要经济学院系互动，影响巴西经济学界的发展。
Abstract This article studies the entanglements of mathematical economics in Brazil by delving into the emergence of a scientific community identified with the subject at the Instituto de Matemática Pura e Aplicada (IMPA). It traces how networks built since IMPA's early years in the 1950s made economics a viable alternative to applied mathematics in an institute mostly dedicated to research in pure mathematics. The article examines how interests in mathematical economics remained active during IMPA's expansion beginning in the late 1960s. This process culminated with the creation of the mathematical economics graduate program at IMPA in 1980 by Aloisio Araujo. The article follows how the program could build strong connections to the Escola de Pós-Graduação em Economia (EPGE), an important department of economics in Brazil, helping to shape recent developments in the center. The article thus aims to reveal how historical connections and entwinements of economics and mathematics groomed at IMPA have affected recent developments in the Brazilian economics community.
