Hi, everyone! I'd appreciate some help with this problem, please.
Suppose that a seller puts a one-unit good on the market, and a buyer comes around with an unknown valuation $θ$. This buyer has a quasi-linear utility function $θq-p,$ and costs are quadratic with $c(q) = \dfrac{1}{2}q^2.$
Now suppose that $θ$ is uniformly distributed on $[0,1].$
Find the optimal direct mechanism $(p(·),q(·)).$
At the moment, I understand that we would need to maximize the seller's expected revenue, though I am not sure to navigate this problem. All help is appreciated.
