IR shock for calculation of effective duration
The interest rate shock in the Appendix Excel file for calculating effective duration is 0.1%.
I believe the value of IR shock will be provided in an exam question, or is 0.1% some sort of default value?

Typically you just need to approximate a very small change so 0.1% is fine; 0.01% is also okay. I think 0.01% (1 basis point) is actually the most common.
