Deformation modes and geometries in the EPICA-DML ice core, Antarctica

Combination of physical-properties methods (crystal-orientation-fabrics, grain-elongation-data, line-scan stratigraphy-documentation) reveal evidences for five deformation geometry regimes:1. Random c-axes distributions and crystal elongation directions (~2020 m depth). Here bed-parallel simple shear deforms the ice causing folding and inclination of stratigraphic layers.5. A last change of geometries is observed at ~2370 m depth, with a locally very restricted (~10 m) backslide to girdle fabric, isoclinal z-folding and borehole closure. Below that an inclined single maximum fabric reoccurs.Simple shear can easily produce the observed small-scale folding of layers which however may belong to disturbances on a larger scale with possible overturning and thus age reversal of layers. Below ~2020 m the EDML climate record has to be interpreted with great care

Modelling the Foreign Sector in a Macroeconometric Model of Sweden

The purpose of this paper is to estimate a rudimentary model of the “rest of the world", which may serve as the foreign sector in a model of the Swedish economy. The “rest of the world" is here represented by the US and the euro zone which together cover some two thirds of the Swedish foreign trade. The underlying theoretical model is the so-called Svensson model as of Svensson (1997). This model has the advantage that it is small and simple, but still allows for both supply and demand shocks with realistic responses. The Svensson model is estimated (OLS) for the US and the euro zone separately using quarterly data. Furthermore, following Smeets and Peersman (1999), alternative models with the outputgap treated as an unobserved component are estimated as well. Impulse response analyses indicate that all individual models react reasonably well to both supply and demand shocks. The models for the US and the euro zone are aggregated temporally to annual data (since the model of the Swedish economy uses annual data) and are subsequently aggregated into one model of the foreign sector.

Uncertainty and Transparency of Monetary Policy

What is the proper degree of central bank transparency? This paper investigates the issue in a framework characterized by: a) common uncertainty on potential output, and b) imperfect knowledge of the central bank target (and inference of the true policy reaction function) by the private sector. We show that full transparency is socially beneficial under a variety of parametrizations. Our results confirm, in a different set up, those of Faust and Svensson (2001, 2002), and Svensson (2006).What is the proper degree of central bank transparency?
