- Circulação monetária em Moçambique: modelação e previsãoPublication . Arone, Samuel G.; Grilo, Luís M.; Nunes, Catarina S.A utilização de notas e moedas metálicas na intermediação de transações económicas depende da preferência de agentes económicos e do público em geral por liquidez, o que levanta desafios na determinação exata da quantidade de meios de pagamento que o Banco Central deve colocar em circulação na economia. Decorrente da relevância das notas e moedas para lubrificar as trocas comerciais, o Banco Central deve, de forma sistemática, adotar um modelo que permita descrever e prever a série de circulação monetária. É neste contexto, que este estudo propõe-se a contribuir na identificação de um modelo que possa auxiliar ao Banco de Moçambique na modelação e previsão da série de circulação monetária em Moçambique. O resultado do estudo indica que, o modelo univariado SARIMA (1,1,0) (0,1,1)12 apresenta boas virtudes para a estimação e previsão da circulação monetária em Moçambique.
