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 directional forecast value in the presence of serial correlation
Blaskowitz, Oliver; Herwartz, Helmut - 2008
Common approaches to test for the economic value of directional forecasts are based on the classical Chi-square test for independence, Fisher’s exact test or the Pesaran and Timmerman (1992) test for market timing. These tests are asymptotically valid for serially independent observations....

A robust bootstrap approach to the Hausman test in stationary panel data models
Herwartz, Helmut (contributor);  … - 2007
In panel data econometrics the Hausman test is of central importance to select an e±cient estimator of the models' slope parameters. When testing the null hypothesis of no correlation between unobserved heterogeneity and observable explanatory variables by means of the Hausman test model...
