In this note the unobserved component approach underlying the software package SEATS is compared with the Beveridge-Nelson type of decomposition for seasonal time series. The main strength of the SEATS approach lies in the appealing model formulation and the careful specification and adjustment...

Models are studied where the response Y and covariates X, T are assumed to fulfill E(Y

The Trust Game describes a situation where mutually beneficial trade is endangered by opportunistic exploitation. In the Trust Game with Banks this dilemma can be avoided by banks guaranteeing that sellers will be paid. This outcome is, however, not the only possible solution. Bank interference...

We propose a method of adaptive estimation of a regression function and which is near optimal in the classical sense of the mean integrated error. At the same time, the estimator is shown to be very sensitive to discontinuities or change-points of the underlying function f or its derivatives....

Testing the cointegrating rank of a vector autoregressive process with an intercept is considered. In addition to the likelihood ratio (LR) tests developed by Johansen and Juselius and others we also consider an alternative class of tests which is based on estimating the trend parameters of the...

In diesem Beitrag wird der vergleichsweise neue Ansatz der 'Strukturellen Vektorautoregression' (SVAR) vorgestellt und anhand einfacher Beispiele illustriert. Auf der Basis der Theorie rationaler Erwartungen wird unterschieden, inwieweit der Einsatz wirtschaftspolitischer Instrumente von den...

The findings on the ultimatum game are considered as belonging to the most robust experimental results. In this paper we present a slightly altered version of the mini ultimatum game of Bolton and Zwick (1995). Whereas in the latter exactly equal splits were feasible in our games these were...
