The Time Varying Parameters Vector Autoregression (TVP-VAR) model introduces frameworks to manage dynamic relationships in multiple economic variables, enhancing forecasts at the zero lower bound.
In the context of the theoretical framework, using independent random walk processes for the coefficients allows the model to adapt to changing economic environments more effectively.
The integration of theory coherent priors such as the Normal-Inverse-Wishart enhances the model's predictive capabilities, providing a more robust framework for analysis in uncertain economic conditions.
Conducting out-of-sample forecasting exercises with varying model specifications underlines the significance of tailored approaches in improving prediction accuracy, especially in complex economic scenarios.
