Possibly incorrect value of omega in US_CCTW10 model #169

I attended Prof. Wieland's Advanced Studies Programme course in Monetary Policy at the IfW Kiel last week. During the course, when we talked about the MMB, we noticed that the US_CCTW10 model has what appears to be an incorrect value of the parameter omega.

Specifically, line 107 of the file static/mmci-cli/models/US_CCTW10/US_CCTW10.mod has the following:

omega=0.5;//.2651;

which should likely be

omega=0.2651;

instead. The paper for this model, Cogan et al. (2010), lists 0.2651 as the posterior mean for this parameter (p. 294, table A1).
