It is not about “a particular ‘crisis’”. “Recessions, panics, crises” are all synonyms for (yet another commonly used word) “bust”…as in “severe economic downturn” (I would have said “recession” but you already used that as a “particular kind of crisis”…which, by the way, I think it should tell you something when you have to use “crises” as a “particular type of crisis”.)
“Lower prices altogether” is not inherently bad, and can come about in 4 different ways. Professor Salerno explains this here:
