Nonparametric change-point analysis of volatility
Bibinger, Markus; Jirak, Moritz; Vetter, Mathias - 2015
This work develops change-point methods for statistics of high-frequency data. The main interest is the volatility of … discriminate different smoothness classes of the underlying stochastic volatility process. In a high-frequency framework we prove … extremely mild smoothness assumptions on the stochastic volatility we thereby derive a consistent test for volatility jumps. A …

What has caused global business cycle decoupling : smaller shocks or reduced sensitivity?
Berger, Tino; Richter, Julia - 2017
According to a growing body of empirical literature, global shocks have become less important for business cycles in industrialized countries and emerging market economies since the mid-1980s. In this paper, we analyze the question of what might have caused a decoupling from the global business...

Changing impact of shocks : a time-varying proxy SVAR approach
Mumtaz, Haroon; Petrova, Katerina - 2018
In this paper we extend the Bayesian Proxy VAR to incorporate time variation in the parameters. A Gibbs sampling algorithm is provided to approximate the posterior distributions of the model's parameters. Using the proposed algorithm, we estimate the time-varying effects of taxation shocks in...

Moments, shocks and spillovers in Markov switching VAR models
Dijk, Dick van; Kole, Erik - 2021
To investigate how economies, financial markets or institutions can deal with stress, we nowadays often analyze the effects of shocks conditional on a recession or a bear market. MSVAR models are ideally suited for such analyses because they combine gradual movement with sudden switches. In this...
