Abstract in Portuguese
A presente pesquisa buscou encontrar se, nos países analisados, as empresas em dificuldades financeiras tiveram reduções em suas medidas de risco sistêmico. No caso afirmativo foi diagnosticado um problema estatístico com a medida e não uma real redução nos níveis de risco sistêmico dessas empresas. Para corrigir esse problema, identificado também em estudos anteriores, foram propostos e testados quatro ajustes, baseados (1) na teoria de opções, (2) na teoria de estrutura de capital, (3) na teoria de carteiras e (4) em medidas puramente contábeis. Os resultados dos dois primeiros ajustes foram consistentes entre si e apresentaram resultados positivos, permitindo que as medidas de risco sistêmico voltem a refletir melhor o mesmo e passem a se comportar conforme a previsão da Teoria de Finanças atual.

For those cases it was diagnosed systematic risk leveis. To correct this problem, already identified by previous studies, four adjustments were proposed and tested, based on (1) options theory, (2) capital structure theory, (3) portfolio theory and (4) purely accounting measures. The results obtained from the first two adjustments were consistent between themselves and presented positive results, allowing the original measures ofsystematic risk to better reflect it and behave as predicted by current financial theory iv a statistical problem within the measures estimation instead of a real reduction of their.
