Contract theory claims that renegotiation prevents attainment of the efficient solution that could be obtained under full commitment. Assessing the cost of renegotiation remains an open issue from an empirical viewpoint. We fit a structural principal-agent model with renegotiation on a set of...

The renegotiation of regulatory contracts is known to prevent regulators from achieving the full commitment efficient outcome in dynamic contexts. However, assessing the cost of such renegotiation remains an open issue from an empirical viewpoint. To address this question, we fit a structural...

This article is an attempt to shed light on the specification and identification of inefficiency in stochastic frontiers. We consider the case of a regulated firm or industry. Applying a simple principal-agent framework that accounts for informational asymmetries to this context, we derive the...

[eng] Econometricians working on stochastic production and cost frontiers have been interested in estimating the inefficiency of firms. At the same time, economists have considered problems of asymmetric information arising in the contractual relationships between principals and agents. This...

We consider a framework of contractual interactions between public transport authorities and transport operators. We estimate simultaneously the contract choice by the authorities and the effect of regulation on the cost-reducing activity of the operators. We test whether the current regulatory...

Bringing together insights and perspectives from close to 70 of the world’s leading experts in the field, this timely Handbook provides an up-to-date guide to the most recent and state-of-the-art advances in transport economics. The comprehensive coverage includes topics such as the...

Despite its great prevalence in practice, competition through whole schedules of prices as function of quantities remains largely unexplored. To deal with this question, the multiprincipal incentive theory is exploited to build a theoretical model of oligopolistic competition which is fitted to...
