In this paper a Canonical Correlation Analysis (CCA) is used to test the hypothesis r = r0 against the alternative r r0. Such a test flips the null and alternative hypotheses of Johansen's LR test and can be used jointly with the LR test to construct a confidence set for the cointegration rank....

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...

Whoever exists belongs to a species, which did not become extinct, has a (geno-) type, which should be well adjusted, and lives in a habitat which has been sustainable for a long time. To capture the first aspect we allow for interspecies competition and analyze the conditions for species...

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...

Modern econometrics requires implementation of highly specialized software. In contrast to mathematical arguments used in implementing new econometric techniques the corresponding software algorithms require specific platforms. The specialization of hardware and software, in fact, seriously...

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...
