Just speculating:

Could the source of denialism be that more supply makes the area more interesting/liveable, hence increasing the price of land (houses, not housing)?

You discuss monitoring costs, but I am not sure you acknowledge “hidden costs of control” arguments that arise in other (non-gig economy) settings where monitoring feels intrusive.

Btw why don’t you have an hourly wage control group? I mean, apart from the fact that it would cost more money to run the experiment...

For example, would you get similar estimates if the task was different (e.g., more/less responsive to effort or requiring more creativity)? Or uncertainty was not on the wage but on task characteristics (e.g., difficulty).

It's interesting and rather unusual to see quantitative estimates based on an online experiment. To be convinced of these estimates, one might expect to see robustness across some dimensions.

Great paper!

A few comments after a quick read:

What about professor supply, is it responding?

I think talent complementarities are generally undervalued (e.g. defensive midfielders in football teams). Do you find this?

When will that slender moment slip through the editorial net—
An AI’s line, so deftly worn, no human hand can detect its seam?
When ink and code become indistinct, vowels and circuits entwined,
The old division, poet and machine, will vanish into a subtle dream.

I would add that experimental papers should be the same, the goal should be to tell a story.

Experiments should not be aimed at testing a model. We already know all models are wrong, what is the point?

I appreciate the move towards more psychologically realistic models, but the idea of building a realistic general model of human behavior is a fantasy.

What is the use of economic models? I'm with Ariel Rubinstein on this; they tell a story/fable. arielrubinstein.tau.ac.il/papers/74.pdf

Economists’ risk measures suck because there is no such thing as risk preferences/attitudes. These are theoretical concepts that have no bearing to reality.

There is an optimal size.

No one goes to the other place anymore, it is too crowded.
