Brazilian sign language: a reflection about the relationship between information asymmetry and welfare

Abstract

This article is about an experience report of conclusions drawn by a teacher working in a professional Sign Language course. We present a brief discussion on the term asymmetry of information relating it to the welfare concept. We also talk about creating laws that promote the Brazilian Sign Language (Libras) and point out the benefits that Libras students had while learning the new language. The classes were part of a project of the Department of Labor and took place at Delta College in the city of Goiania. Most of the researches done show the difficulties that permeate the communication of the deaf subject; in this report, however, the goal is to show that the lack of knowledge of the language is also detrimental to the listeners. The relevance of the work is justified by the need to create public policies that encourage the dissemination and expansion of the use of Sign Language in the country as a crucial factor in breaking down language barriers.
