报告摘要：

The econometrics method we use is “unit root test”. This applied econometrics test plays an important role in mainstream economics research as it was developed by Dickey and Fuller (1979) , numerous surveys and studies introduced this method since then (see, Perman,1991; Campbell and Perron , 1991; and Dolado et al., 2006). Several important topics in economics and finance adopts unit root test, including purchasing power parity, unconditional income convergence hypothesis, and financial market bubbles , corporate profit persistence, financial leverage mean reversion, and price convergence. Unit root test is used to test for the stationarity of a time series. In this session we will examine the development of this methodology.

报告摘要：

This seminar session introduces the spillover approach newly developed by Diebold and Yilmaz (2009, 2012, 2014, and 2015) in constructing static and dynamic interconnectedness among variables in major financial markets. In particular, this approach is mainly based on forecast error variance decomposition associated with the VAR model. This method has been applied to several empirical finance topics (e.g. Ji et. al ; 2019; Apergis, Baruník, & Lau; 2017).
