Alexis presented his recent project "Robust regulation of labour contracts", joint with Théo Durandard (UIUC), at the theory seminar at UIUC. This paper studies the problem of a regulator, aiming to improve efficiency and protect workers, who can decide what contracts a firm can offer to a worker. The model of the firm-worker interaction is a standard principal-agent model with moral hazard. In that setting, the regret-minimizing regulation consists of a linear minimum wage. The regulator allows the firm to offer any contract that is pointwise greater than a linear contract. Very good reception from the audience and good feedback from Dan Bernhardt and Stefan Krasa.
