Financial Contagion · Network Econometrics · State-Space Models
What role do financial networks play in the contagious spread of default risk? Do they amplify or do they dampen?

This, in a nutshell, is the guiding question for my research. As a visiting researcher at De Nederlandsche Bank, I'm able to find answers to this crucial question with the help of detailed supervisory datasets. Since contagion is unobserved and inherently dynamic, I develop a new class of spatial econometric state-space models to extract policy-relevant signals of the network. However, because the estimation of such highly nonlinear time series models with stochastic volatilty is challenging, I use simulation-based methods such as importance sampling or particle filters. My research is programmed in Python and I use JavaScript for interactive apps. For example
