This paper examines how regulatory interventions can affect the market risk of electricity utilities and telecom carriers traded in the Brazilian stock market. Our article uses a bivariate Generalized AutoRegressive Conditional Heteroskedasticity (GARCH - BEKK) model to analyze the impact of two...

This article aims to estimate the dynamic factor model for prediction tax receipts in Brazil using monthly data for the period 2001-2013. The factorial model allows to reduce the dimensionality of the high number of taxes taking into account the information contained in the existing...

This paper aims to compare two different methodologies to estimate exchange rate misalignment. The first methodology consists in using multivariate time series techniques and a model with domestic variables. The second methodology consists in Pesaran's Global Vector Error Correction Model with...
