Who has the incentive to present evidence as a creation rather than a discovery?
Stating that evidence "creates" the equivalence of sensitivities (like equation 25 in our context) ignores the fact that it merely formalizes an intrinsic property.
If all market participants claimed to create the fundamental relationships they discover, the incentives for true innovation would disappear; thinking that a proof generates this equivalence is nonsensical.
For example, the discovery that real interest rates in Brazil impact capital flows did not "create" this relationship; it made it exploitable for traders.
