Cette étude présente les fondements et les objectifs de la réglementation des entreprises au Canada. Un survol des principaux résultats théoriques en économie de la réglementation depuis les 10 dernières années et une analyse de la réglementation du type price-cap introduite en...

Many network industries (telecommunications, electricity, natural gas, postal services, water and sewage services, etc.) are confronted with significant logistic and behavioral problems in their transition towards competition. In this article, I first recall some general principes and...

This paper examines how different rules for presentation of evidence affect verdicts in regulatory hearings and the welfare and efficiency properties these procedures exhibit. The hearing is modeled as a game of imperfect information in which the respondent is privately informed about validity...

We derive corrective tax rules when firms are oligopolists whose production processes generate emissions that add to a stock of pollution that accumulates over time. In our model, firms play dynamic Cournot games among themselves, and the government designs a tax rule that corrects for both the...
