"It’s worth noting that the 'Dunning-Kruger curve' never appeared in the original paper and is basically a meme based on a misunderstanding(?) of the effect. Nevertheless, it resonates with a lot of people."
Hi - gamma is defined as [average time spent on market]/[average time spent off market] for someone who isn't lying. This depends on what kind of job obviously, but if it's the norm for people to spend 1 year unemployed for every 15 years employed, then gamma = 1/15. The claim is that the lower the gamma, the higher proportion of liars in the job candidate pool.
