The Importance of Trade Sanctions in the Media

The key issue is the parameterization of these elasticity as substitution. How easy is it for Germany to find a substitute to Russian gas or to Russian oil? And typically that's difficult to calibrate, and so the state of literature is often to actually run a lot of what we call sensitivity analysis.

I suppose there's a little bit of both.
