Consistent factor estimation in dynamic factor models with structural instability

Forecasting in Dynamic Factor Models Subject to Structural Instability

Tests for Parameter Instability in Dynamic Factor Models

We develop tests for structural breaks of factor loadings in dynamic factor models. We focus on the joint null hypothesis that all factor loadings are constant over time. Because the number of factor loading parameters goes to infinity as the sample size grows, the conventional test cannot be used. Based on the fact that the estimated factors will demonstrate a higher dimension under the altern...

Forecasting with dynamic factor models

The validity of previous findings that dynamic factor models are useful for macroeconomic forecasting is of great importance for subsequent studies which use these models not only as a starting point for further developments but also as a benchmark for the evaluation of the forecasting performance of these further developments. Reanalyzing a standard macroeconomic dataset, we do not find any ev...

Dynamic Hierarchical Factor Models ∗

This paper presents an approach to dynamic factor modeling in which variations can be idiosyncratic, block-specific, or common across blocks and units. Existing two level factor models do not usually account for variations at the block level which implies that these can be confounded with genuine common co-movements in the data. Specifying the block structure also facilitates interpretation of ...

Dynamic Semiparametric Factor Models

High-dimensional regression problems which reveal dynamic behavior occur frequently in many different fields of science. The dynamics of the whole complex system is typically analyzed by time propagation of few number of factors, which are loaded with time invariant functions of exploratory variables. In this thesis we consider dynamic semiparametric factor model, which assumes nonparametric lo...
