"New graduates can command $100,000 a year in Silicon Valley. Hired has found that bumping the offer up to $120,000 gives you access to 30% more candidates."
This is something many people on HN have been saying for a long time in response to the question of whether the US needs to create more H-1B visas: companies have a hard time finding qualified employees because they don't want to pay enough. It's nice to see the numbers quantified in this way (even though this is only anecdotal evidence from a single recruiting firm).
