This paper test the null hypothesis of linearity against a specific form of nonlinearity in the Data Generating Process (DGP) of the unemployment rate and the difference between the inflation rate (measured as the twelve months variation of CPI and CPIX1) and the inflation target, using twenty...

This paper explores the virtues of Markov-Switching models to characterize the behavior of copper price. In particular, we study the performance of several univariate specifications of this type of models, both in and out of sample, comparing them also with constant parameter models such as ARMA...

This paper tests the hypothesis of linearity against a specific form of nonlinearity in the Data Generating Process (DGP) of the unemployment rate and the difference between the inflation rate (CPI and CPIX1) and the inflation target. The test is performed over each variable using time series...
