Testing directional forecast value in the presence of serial correlation
Blaskowitz, Oliver J.; 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....

When, how fast and by how much do trade costs change in the Euro area?
Herwartz, Helmut; Weber, Henning - 2008
Microfoundations of the euro's effect on euro area trade hinge on the timing, the speed and the size of adjustment in … at the sector level. We find that, due to falling trade costs, trade within the euro area increases between the years … 2000 and 2003 by 10 to 20 percent compared with trade between European countries that are not members of the euro area …

Exchange rate uncertainty and trade growth: a comparison of linear and nonlinear (forecasting) models
Herwartz, Helmut; Weber, Henning - 2007
A huge body of empirical and theoretical literature has emerged on the relationship between foreign exchange (FX) uncertainty and international trade. Empirical findings about the impact of FX uncertainty on trade figures are at best weak and often ambiguous with respect to its direction. Almost...

Modeling the FIBOR/EURIBOR swap term structure: an empirical approach
Blaskowitz, Oliver J.; Herwartz, Helmut; Cadenas … - 2005
In this study we forecast the term structure of FIBOR/EURIBOR swap rates by means of recursive vector autoregressive (VAR) models. In advance, a principal components analysis (PCA) is adopted to reduce the dimensionality of the term structure. To evaluate ex-ante forecasting performance for...

On economic evaluation of directional forecasts
Blaskowitz, Oliver J.; Herwartz, Helmut - 2009
It is commonly accepted that information is helpful if it can be exploited to improve a decision making process. In economics, decisions are often based on forecasts of up- or downward movements of the variable of interest. We point out that directional forecasts can provide a useful framework...
