WebMy current research focuses on the analysis of inflation, productivity, monetary policy transmission, nowcasting GDP, and global financial cycles. I work with advanced macroeconometric methods such as dynamic factor models, Bayesian VAR models and time-varying parameter models. WebIn factor models, noises are often assumed to be weakly correlated; otherwise, separation of factors from noises becomes difficult, if not impossible. This paper will address this problem. We utilize an econometric idea, the so called common correlated effects (CCE) to estimate time varying factor models.
On Time-varying Factor Models: Estimation and Testing[J.
WebThe time variation in factor loadings can distort the standard factor model tests, which assume constant betas, for whether the alphas are equal to zero and, thus, renders traditional statistical inference for the validity of a factor model to be possibly misleading in the presence of time-varying factor loadings.

Webmodel with time-varying factor loadings as an extension of the classical factor model based on Su and Wang(2024). This new model can be used for mortality modelling and forecasting by developing corresponding estimation and forecasting methods. As the time-varying factor model allows for time-varying factor loadings, it provides more Web30 de nov. de 2024 · Abstract. The emergence of large datasets with long time spans has cast doubt on the assumption of constant loadings in conventional factor models. Being a potential solution, the time-varying factor model (TVFM) has attracted enormous interest in the literature. However, TVFM also suffers from the well-known problem of … Webtime-varying or time-invariant factor models. Based on the comparison between the estimates of the common components under the null hypothesis of no structural changes and those under the alternative, we propose a consistent test for structural changes in factor loadings. iowa consumer loan license
