Bank ownership, rm value and rm capital structure in Europe*

We investigate the role of banks in the ownership structure of non-…nancial …rms. Distinguishing between banks and other institutional investors as shareholders, we examine the relationship between …nancial institution ownership and the performance of the …rms in which they hold equity. We control explicitly for the capital structure decision of the …rms and the ownership decision of …nancial i...

Identifying an Honest ${\rm EXP}^{\rm NP}$ Oracle Among Many

We provide a general framework to remove short advice by formulating the following computational task for a function f : given two oracles at least one of which is honest (i.e. correctly computes f on all inputs) as well as an input, the task is to compute f on the input with the help of the oracles by a probabilistic polynomial-time machine, which we shall call a selector. We characterize the ...

Structures in the RM sky

Coherent structures in the distribution of the Faraday rotation measure of extragalac-tic radio sources are isolated using wavelet transformation technique. A new algorithm of wavelet analysis for data points nonuniformly distributed on a sphere is developed and implemented. Signatures of the magnetic fields in the local (Orion) spiral arm, the Sagittarius and Carina arms, the synchrotron Loop ...

On Interactions in the RM-ODP

The RM-ODP definition of interaction is subtle and difficult to understand. On closer inspection, we find that it is in fact invalid. We then attempt to establish the author’s original intentions for this concept, and to provide an effective definition. Our investigations lead us to discover some fundamental flaws in the definitions of interface and of behaviour of an object.
