Professional Forecasters: How to Understand and Exploit Them Through a DSGE Model
This paper derives a link between the forecasts of professional forecasters and a DSGE model. I show that the forecasts of a professional forecaster can be incorporated to the state space representation of the model by allowing the measurement error of the forecast and the structural shocks to be correlated. The parameters capturing this correlation are reduced form parameters that allow to address two issues i) How the forecasts of the professional forecaster can be exploited as a source of information for the estimation of the model and ii) How to characterize the deviations of the professional forecaster from an ideal complete information forecaster in terms of the shocks and the structure of the economy.Mercado laboral, VAR estructural, DSGE, Economía abierta, Política monetaria.

Computational studies on the behaviour of anionic and nonionic surfactants at the SiO (silicon dioxide)/water interface
Molecular dynamics simulations to study the behaviour of anionic (Sodium
Dodecylsulfate, SDS) and nonionic (Monooleate of Sorbitan, SPAN80) surfactants
close to a SiO (silicon dioxide) surface were carried out. Simulations
showed that a water layer was first adsorbed on the surface and then the
surfactants were attached on that layer. Moreover, it was observed that water
behaviour close to the surface influenced the surfactant adsorption since a
semi-spherical micelle was formed on the SiO surface with SDS molecules
whereas a cylindrical micelle was formed with SPAN80 molecules. Adsorption of
the micelles was conducted in terms of structural properties (density profiles
and angular distributions) and dynamical behaviour (diffusion coefficients) of
the systems. Finally, it was also shown that some water molecules moved inside
the solid surface and located at specific sites of the solid surface.Comment: 8 pages, 6 fiigure
