Similarity evidence between the country risk and the idiosyncratic risk: An empirical study of the Brazilian case

Abstract: Purpose ─ This paper estimates the idiosyncratic risk (IDR) time series in the Brazilian economy and verifies its interaction with the Brazilian country risk indicators, measured by the EMBI+ (the Emerging Markets Bond Index).Methods ─ This paper estimates various regression models to capture the dynamic nature of the variables. The models include the heteroscedastic conditional autoregressive models and vector error correction models (VECM).Findings ─ The results show similarities or associations between the … Show more

“…4 illustrates the perceptron model, which, in its configuration, harbours numerous inputs and outputs, representing input values as x 1 , x 2 , and x 3 , whilst the activation function is denoted by f . The model identifies a linear relationship between inputs and outputs, consequently generating intermediate output results [28]. Given Eq.…”
