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 …

Panel data model comparison for empirical saving-investment relations

Herwartz, Helmut; Xu, Fang - 2006

The low capital mobility among OECD countries, signalled by a high saving-investment (SI) relation and known as the Feldstein-Horioka puzzle, has triggered a lively discussion in the empirical literature. In this paper, we compare between, pooled, time and country dependent specifications of the...

A functional coefficient model view of the Feldstein-Horioka puzzle

Herwartz, Helmut; Xu, Fang - 2007

What does the saving-investment (SI) relation really measure and how should the (SI) relation be measured? These are two of the most discussed issues triggered by the so called Feldstein-Horioka puzzle. Based on panel data we introduce a new variant of functional coefficient models that allow to...

A new approach to bootstrap inference in functional coefficient models

Herwartz, Helmut; Xu, Fang - 2007

We introduce a new, factor based bootstrap approach which is robust under heteroskedastic error terms for inference in functional coefficient models. Modeling the functional coefficient parametrically, the bootstrap approximation of an F statistic is shown to hold asymptotically. In simulation...
