how much has economics changed?

from 2011 to 2013? arif irfanullahs site says it has changed entirely? really? am concerned just with the macro part

From 2011? Yes it has changed completely.

yes it has changed entirely, he doesnt have videos for Econ on youtube, also alternative investments has changed but you can still see video on Commodities. And in fixed incomes, he hasnt covered fundamentals of credit analysis. Rest of the videos are good for December 13.
