Financial and Macroeconomic Connectedness: A Network Approach to Measurement and Monitoring

With Kamil Yilmaz, Professor of Economics at Koç University

5-6 September 2022

Classes: 9am -12pm, 1.30pm - 4.30pm
University of Glasgow Main Building

We provide a brief review of vector autoregressions, introduce the connectedness framework, cover a variety of applications, and supply and illustrate software that you can use and modify for your applications.

Who should attend

Economists who want to understand recent developments in measuring, monitoring, and modeling network connectedness in financial institutions, financial markets, and underlying macroeconomic fundamentals. 

Course level

Intermediate / advanced

Topics covered

The lectures will be drawn from Financial and Macroeconomic Connectedness (FMC) and the listed articles, covering both methods and applications. The applications will emphasise financial institutions, markets, and the underlying macroeconomic fundamentals.

Software requirements

R (intermediate level)

Learning outcomes

By the end of this course, you will be able to:

  1. build and estimate high dimensional VARs for joint modelling of time series and undertake impulse response and variance decomposition analysis,
  2. programme and estimate aggregate and granular measures of connectedness and analyse how shocks to a system of variables propagate across the system and overtime,
  3. Apply the connectedness analysis to financial and macroeconomic time series and undertake graphical and econometric analysis of the determinants of the connectedness over time.
