Introduction
I am an associate professor of management at Sorbonne Business School / IAE Paris - Université Paris I Panthéon-Sorbonne. I work on contracting between public and private actors for the provision of public services. I am currently extending my research to the use of AI in government and the interplay between culture, institutions and the quality of government.

The concept of agility underscores how fast actions, responsiveness to users’ experiences, and adaptive structures enable governments to address problems arising from rapidly changing environments. Applying the concept to government responses to COVID-19, we examine whether a government’s early mandate adoption enhances its eventual efficacy and ho...
Article
How can districts become completely embedded in informal economies despite harsh state regulation? In this paper, we use qualitative and quantitative data to explain the increasing number of ‘clandestine’ street-level prostitutes in a district of Paris during the Belle Epoque (1870–1914). Using an original dataset on street-level prostitutes, we de...

What is the best governance mode (i.e., hierarchy or the market) to provide public services? The choices of governance modes have been scrutinized by scholars in public management and public administration over the last several decades (Kettl, 1993; Savas, 2000; Sclar, 2000). The question of the governance mode of public service provision is typica...

Article
This article uses a cross‐country data set to empirically investigate the relationship between national culture and the quality of government. Culture has a strong impact on the quality of government that remains stable even after controlling for differences in institutions and economic development. This effect remains significant when the continen...

Article
L’approche des tarifs de l’eau potable en France a changé depuis 2010, puisque les collectivités peuvent recourir à des tarifs progressifs croissants par blocs. Ces tarifs, bien qu’initialement conçus comme des solutions de second rang aux pertes sèches du monopole, se révèlent complexes à mettre en œuvre pour satisfaire d’autres objectifs. La réac...

Celle-ci permet de traiter un nombre très important de données afin de prendre des décisions stratégiques, managériales ou marketing. Le livre est basé sur les cours enseignés depuis plusieurs années par les trois enseignants à l’IAE de Paris, l’IAE Gustave Eiffel et la London Schoo...
Article
The privatization of the water industry has aroused interest in comparing the performance of public vs. private water companies. However, little research has been conducted to compare the performances of full private (FPWCs) and concessionary water companies (CWCs). This study estimates and compares the productivity growth and its drivers (efficien...

Fuel taxes can be employed to correct externalities associated with automobile use and raise government revenue. The general understanding of the efficacy of existing taxes is largely based on empirical analyses of consumer responses to fuel price changes. In this paper, we directly examine how fuel taxes, as distinct from tax-exclusive fuel prices...

In France, the management of public services such as water or sanitation can be done by the municipal council or contracted out to a private operator. This paper quantifies the impact of the choice of contracting out the management of water public services on price. It uses a unique dataset of utilities with unusual detailed financial indicators, s...

The assessment of productivity change over time and its drivers is of great significance for water companies and regulators when setting urban water tariffs. This issue is even more relevant in privatized water industries, such as those in England and Wales, where the price-cap regulation is adopted. In this paper, an input-distance function is use...
Article
The evaluation of the economic efficiency of regulatory schemes is essential for regulators and utilities. In this study it is analysed for the first time the welfare costs of non-marginal cost pricing in the water supply in England and Wales, by computing the deadweight loss of the water only companies (WoCs) that existed over the period of 1993–2...

The spot commodities market exhibits both extreme volatility and price spikes, which lead to heavy-tailed distributions of price change and autocorrelation. This article uses various Lévy jump models to capture these features in a panel of agricultural commodities observed between January 1990 and February 2014. The results show that Levy jump mode...

As market intermediaries, electricity retailers purchase electricity from the wholesale market or self-generate to deliver' to their customers. However, electricity retailers are uncertain about how much electricity their residential customers will use at any moment of the day until the customers actually turn on their switches. While demand uncert...

Analytical frameworks of government service contracting decisions typically focus on the make-or-buy decision. In concepts, governments can either produce the service itself (make) or outsource production (buy). However, governments make and buy the same public services, a practice that is termed concurrent sourcing. Drawing on transaction costs ec...
Article
It has been documented that retail gasoline prices respond more quickly to increases in wholesale prices than they do to decreases in wholesale prices. However, there is little empirical evidence that identifies the link between the pass-through of oil prices to gasoline in different volatility regimes. Using a Markov-switching model on weekly obse...

Article
This paper integrates transaction cost economics with the resource-based view of the firm to examine how transaction hazards and cities' capabilities influence governance decisions in public-private contracting schemes. We focus here on two levels of governance choice, the lease-manage decision of the service and the make-or-buy decision at the uti...

This paper uses a regime-switching model that is built on mean-reverting and local volatility processes combined with two Markov regime-switching processes to understand the market structure of the French fuel retail market over the period 1990-2013. The volatil-ity structure of these models depends on a first exogenous Markov chain, whereas the dr...

In this article, we consider a discrete-time economy in which we assume that the short-term interest rate follows a quadratic term structure in a regime-switching asset process. The possible nonlinear structure and the fact that the interest rate can have different economic or financial trends justify regime-switching quadratic term structure model...
Article
When studying oligopolies, a tension exists between models supporting tacit collusion and those supporting the noncollusive behaviour of firms. Using a panel on retail fuel margins in France over more than 20 years, we find mitigated evidence of collusive behaviour in the retail gasoline industry. On the one hand, we find lower margins when demand...

The article studies the correlation structures of a large panel of agricultural commodities prices between January 1990 and February 2014. We use a various collection of mathematical and statistical methodologies (estimated correlation matrix and principal component analysis) to capture these correlations. Our results show that there exist differen...

This article uses a data envelopment analysis (DEA) and a stochastic frontier analysis (SFA) to assess the relative technical efficiency of 177 decision-making units in the French water supply sector in 2009. Water utilities can be directly managed by the local authorities or contracted out and then managed by a private operator. The use of a three...
Article
Full-text available
As first noticed by Coase (1946), a standard result in utility regulation is that efficiency requires two-part tariffs with marginal prices set to marginal costs and fixed fees equal to each customer’ s share of fixed costs. Residential water customers in France face marginal prices for water that average about 8% more than marginal costs. Under pr...

We estimate an empirical model with variables for the distance to the technology frontier, regulation, as well as interaction terms between them. We estimate the model at the industry level and report evidence that the marginal effect of regulation on ICT intensity does not become more adverse even at the technological frontier. Our results show th...
