ANÁLISE DO RISCO SETORIAL COMO INSTRUMENTO DE CONTROLE GERENCIAL EM INSTITUIÇÕES FINANCEIRAS Ivan Ricardo Gartner Tito Belchior Silva Moreira Herley Martins Galves Administración y Contabilidad Risco setorial Análise de crédito Instituições financeiras Processo de análise hierárquica Métodos multicritérios de análise de decisão O processo de tomada de decisões de financiamento e investimento é influenciado pelo grau de risco inerente às variáveis consideradas. Este artigo enfoca as variáveis de risco dos setores e segmentos econômicos, que condicionam as decisões das instituições financeiras quanto à concessão do crédito, bem como seu controle durante o período do financiamento. O objetivo é apresentar uma forma alternativa de avaliar o grau de risco dessas variáveis, utilizando uma abordagem que agregue a multiplicidade de critérios das mais diversas dimensões em um sistema único de avaliação. Para tanto, foi utilizado o método AHP; os resultados da aplicação apresentam uma proposta de classificação de risco dos setores e segmentos econômicos da economia brasileira. 2009 artículo científico 1518-6776 https://www.redalyc.org/articulo.oa?id=195415633006 pt http://www.redalyc.org/revista.oa?id=1954 RAM.
