Exchange rates, foreign currency exposure and sovereign risk
Bernoth, Kerstin; Herwartz, Helmut - 2019
We quantify the causal link between exchange rate movements and sovereign risk of 16 major emerging market economies (EMEs) by means of structural vector autoregressive models (SVARs) using data from 10/2004 through 12/2016. We apply a novel data based identification approach of the structural...

A structural approach to identify financial transmission in distinguished scenarios of crises
Herwartz, Helmut; Roestel, Jan - 2018
This paper investigates the propagation of instability through key asset markets of the US financial system - equity, real estate, banking and treasury - between 1/3/2000 and 12/26/2014. For this purpose, we develop an identification method to uncover characteristic financial market...

Global credit shocks and real economies
Herwartz, Helmut; Ochsner, Christian; Rohloff, Hannes - 2021
We estimate the marginal effects of identified components of global liquidity on 43 real economies. To this end, we employ global public and private credit components of Herwartz, Ochsner, and Rohloff (2021) in factor-augmented vector-autoregressions to trace credit shocks through the real...

The euro’s trade effect under cross-sectional heterogeneity and stochastic resistance
Herwartz, Helmut; Weber, Henning - 2010
This paper investigates if the euro's effect on euro-area trade differs across trade sectors and across country pairs …, and to what degree heterogeneity matters for estimating the aggregate euro effect. Time-varying latent variables, which …, aggregate exports within the euro area increase between 2000 and 2002 by 15 to 25 percent compared with aggregate exports …

Testing for causality in variance using multivariate GARCH models
Hafner, Christian M. (contributor);  … - 2004 - [Elektronische Ressource]
Tests of causality in variance in multiple time series have been proposed recently, based on residuals of estimated univariate models. Although such tests are applied frequently little is known about their power properties. In this paper we show that a convenient alternative to residual based...
