Summary/Abstract: This study present an operational characterization of contemporaneity among variables based on the transformation of their corresponding time series into symbolic ones by applying either a Markov switching approach or the symbolic aggregate approximation method. Then, the authors extract vectors from the resulting symbolic time series, characterizing the pattern of change or permanence in time. The scalar product between the vectors corresponding to two variables yields the index of contemporaneity between them. The study apply this method to detect a ranking of synchronic patterns of evolution of gross domestic product (GDP) and investment between several South American economies.
