I'm writing a speech, which has a sentence to the effect of:
Even as COVID-19 continues to cause people to leave the region for cheaper pastures, resulting decreases in expected salary for remote work often underestimate actual decreases in cost of living.
I'm trying to express that one quantity follows another — in this case salaries and cost of living, respectively — but the former often doesn't follow the latter to quite the same magnitude.
Here's a phrase from the sentence above, and a few possible rewordings to better specify the meaning I'm looking for:
decreases in expected salary often underestimate actual decreases in cost of living
as cost of living decreases, so does expected salary, but not as much
as expected salary falls following cost of living, it doesn't decrease to quite the same degree
Non-words that approximate the meaning I'm looking for are:
Trails gets close, but indicates time lag rather than "underproportionalizing".
Is there a word for this, or something close?
