In France, the reform of the judicial map, initiated in mid-2007 and completed in 2010, led to a large reduction in the number of courts of first instance, from almost 500 to around 300. This led to an increase of about eight kilometers in the distance litigants should travel to courts in the treated jurisdictions. In this paper, we examine the imp...

This paper relies on a natural experiment to study the short-term consequences of a reduction of the trawler fleet on the economic situation of fisheries. In the context of the Covid pandemic, a scenario of cooperation leading to a weekly rotation of trawlers was set up for four weeks in May 2020 in the port of Le Grau-du-Roi located on the Mediter...
Article
In this paper, we conduct a multi-criteria correspondence test to assess the extent of discrimination in access to employment against candidates with a hearing disability and compare it to three other potential grounds for discrimination: ethnicity, place of residence and gender. From October 2019 to February 2020, we sent 2315 applications to 463...
Article
While there is widespread evidence that sentences for similar cases tend to differ across courts, the production of sentencing disparities by prosecutors versus judges has received very limited attention to date. In this paper, we focus on this issue using traffic offenses data from neighboring courts in South-East France. First, we measure dispari...
Article
Studies on price trends of seafood products in the medium run remain scarce. In this paper, we investigate changes in first-sale prices of fish sold in France over the last 25 years.

We develop a flexible framework for the estimation of the fuel consumption-speed curve for ships which allows for speed-dependent elasticity with endogenous thresholds. Using a large dataset of noon reports for 16 crude oil tankers, we estimate the corresponding elasticities net of weather effects. Our empirical findings confirm that the classical...

In this paper, we investigate the effects of the Danish seine which was introduced for a subsample of vessels on a single wholesale fish market in France. The goal was to mitigate the decrease in vessel profits due to the rise of gasoline prices. Estimations are conducted from transaction data over the 2009–2011 period during which the innovation w...
Article
Around 50% of individuals obtain or hear about jobs through social networks. This hiring trend may become problematic when the labor market is tight and people need less social contacts to find a job. Using a one-period static model where network members may receive job offers directly from the firm or indirectly through employed members in the net...

This paper investigates the effect of semi-liberty as an alternative to prison on recidivism in France. Our analysis is based on a unique dataset comprising 1,445 offenders, all eligible to semi-liberty. In the absence of an instrumental variable affecting access to semi-liberty but unrelated to recidivism, we turn to selection-on-observable method...

Offshore Support Vessels (OSVs) deal with time-sensitive logistics and sophisticated marine operations for high-value offshore oil and gas installations. We investigate whether this creates preferences that effectively penalize energy efficiency, either through lower hire rates or reduced utilization. We apply hedonic pricing fixed effect models wh...
Article
This paper contributes to the literature on the health-retirement relationship by looking at the effect of retiring before legal age on health in later life in France. To account for the endogeneity of the early retirement decision, our identification strategy relies on eligibility rules to a long-career early retirement scheme introduced in France...

BACKGROUND In recent years, large numbers of migrants have attempted to reach Europe by crossing the Mediterranean Sea. Italy plays a central role as a receiving country, particularly because of its relative proximity to the coast of North Africa. OBJECTIVE This paper investigates the trajectories of migrants from their entry into a refugee centre...
Article
Migrants who intend to stay permanently in the host country are less likely to be attached to their origin country, meaning that a temporary migration should increase the likelihood of sending financial transfers to the origin country. We test the relevance of this hypothesis using a unique dataset on the integration of first-generation migrants li...
Article
This paper investigates whether the energy efficiency of vessels is reflected in sales prices in the second-hand market. Using unique data of nearly 1600 sales transactions over a 21-year period, we consider a hedonic pricing framework in which we control for market conditions, vessel specifications and buyers’ country of origin to identify the spe...

The succession of maritime accidents in the last decades of the 20th Century caused a strong political and public outcry for more stringent maritime safety regulations and measures. One of the most significant developments in this regard was the establishment of several regional agreements on Port State Control (PSC) – the first of which was the Pa...

Numerous articles dealing with stated preferences are published every year in journals related to agriculture, environment, or health. Hence, it is not easy to find all the relevant articles when performing a benefit transfer, a meta-analysis, or a review of literature. Also, it is not easy to identify trends or common practices in these fields reg...

Interval bidding allows people to report a range of values for a non-market good. Herein, we allow people to choose their distribution over this range endogenously. We consider a multiplicative error model explaining the willingness to pay (WTP) which is estimated using a feasible generalized least squares estimator. We apply our framework to a rep...

National Transfer Accounts (NTA) measure the way in which individuals produce, consume, save, and share resources at each age. They make it possible to identify the periods for which private and public consumption (education, healthcare, etc.) is not funded by labour income, before identifying the transfers between the ages that enable such consump...

This paper examines the impact on cigarette sales of the successive increases in cigarette prices in France from 2002 to 2004. Since the price differential between France and neighboring countries increased over the period in question, cross-border purchases became more financially attractive for smokers living near borders. Results from difference...

La méthode des Comptes de transferts nationaux est utilisée pour quantifier les transferts économiques entre les âges. Aux âges actifs, les individus produisent en général davantage qu’ils ne consomment. L’inverse s’observe pendant la jeunesse et la retraite, la consommation étant alors financée par une redistribution des ressources entre les âges....

This article empirically investigates the relationship between price dispersion and price level. Searches seem more valuable for products of high quality, but buyers may have little incentive to search since such products are less frequently purchased. The extent of price dispersion is examined using a sample of around 160 000 diamonds offered for...

Using a unique data set on immigrants living in France in 2003, we investigate whether Muslims invest differently in their children’s education compared to non-Muslims. In particular, we want to assess whether educational inequalities between the children of Muslim and non-Muslim immigrants stem from differences between or within families. After co...

We use the National Transfer Accounts methodology to calculate the lifecycle deficit in France for the years 1979–2005. During this period, consumption profiles were roughly constant over age, while labor income profiles shifted to higher ages. The share of the aggregate lifecycle deficit in GDP rose sharply in the 1980s due to an increase in the m...

Hedonic price regressions have become a standard tool to study how prices of commodity goods are related to quality attributes. In this paper, we extend the traditional price specification by incorporating three sources of unobserved heterogeneity related to sellers, buyers, and matches between buyers and sellers. The extended price specification i...

Since Akerlof’s theory of lemons, economists have viewed quality uncertainty as an informational advantage for sellers. Drawing on frontier techniques, we propose in this paper a simple method for measuring inefficiency of both sellers and buyers in markets for goods with different levels of quality. We apply a non-parametric robust double-frontier...
