This article reconsiders the nature of the trends (i.e. deterministic or stochastic) of the Nelson-Plosser macroeconomic time series. For this purpose, the article employs two new tests that display robustness to structural breaks of unknown forms, irrespective of the date and/or location of the...

This paper applies a set of unit root and cointegration tests with non-linear error-correction mechanisms to a subset of the OECD countries to investigate the empirical conclusions of some of the labor market models in the literature. I generally find that the unemployment rate, productivity,...

This paper reconsiders the nature of the trends (i.e. deterministic or stochastic) in macroeconomic time series. For this purpose, the paper employs two new tests that display robustness to structural breaks of unknown forms, irrespective of the date and/or location of the breaks. These tests...

This book proposes new methods to value equity and model the Markowitz efficient frontier using Markov switching models and provide new evidence and solutions to capture the persistence observed in stock returns across developed and emerging markets

This book investigates several competing forecasting models for interest rates, financial returns, and realized volatility, addresses the usefulness of nonlinear models for hedging purposes, and proposes new computational techniques to estimate financial processes
