This paper investigates the problem of testing for the symmetry of linear time series driven by asymmetric innovations. In particular, we examine the performance of alternative symmetry tests when innovations are fat tailed. Among the tests considered, only the test based on the tail estimator...

Nonlinear dynamics in the term structure of German interest rates resulting from heterogenous transaction costs in the money market are analyzed by means of the smooth transition technique introduced by Granger and Terasvirta (1993). Tests for linearity, specific functional forms and outliers...

The European Central Bank uses a monetary strategy which represents a combination of monetary targeting and direct inflation targeting. In this context, the stability of the long-run European money demand function is widely seen as a precondition for a strategy of monetary targeting. This paper...
