-+ [Michaillat and Saez (2024)](/15.pdf) – This paper develops a business-cycle model with divine coincidence: inflation is on target when unemployment is efficient. The model uses the structure of the dynamic model of slack in Michaillat and Saez (2022) and generates price dynamics by introducing price competition through directed search. To ensure that unemployment fluctuates, the model uses price rigidity through quadratic price-adjustment costs.

The model uses the structure of the dynamic model by Michaillat and Saez (2022) and generates a Phillips curve by introducing price competition through directed search.
