Two orthogonal, precise and low drift tiltmeters have been installed in the Vosges mountains in order to study environmental surface loading. The first results show the great sensitivity (10−10 radians), stability (negligible drift) of the instrument, and its ability to be used as a tool to study hydrological loading. This work focuses on local and regional hydrological physical modelling, with...

State-space modeling and Bayesian analysis are both active areas of applied research in fisheries stock assessment. Combining these two methodologies facilitates the fitting of state-space models that may be nonlinear and have non-normal errors, and hence it is particularly useful for the modeling of fisheries dynamics. Here, this approach is demonstrated by fitting a non-linear surplus product...

Diversi®ed ®rms trade at a discount relative to comparable portfolios of stand-alone ®rms. One explanation is that these ®rms have inecient internal capital markets. We examine the link between ®rm value and the value of internal capital markets using a new form of corporate restructuring called tracking stock. We present a model that illustrates that the announcement e€ect of a tracking stock...
