La maladie liée aux immunoglobulines de type G4 (ML-IgG4) est reconnue depuis le début des années 2000 comme une entité regroupant un ensemble de maladies inflammatoires à caractéristiques histopathologiques communes. Pouvant atteindre quasiment tous les organes et tissus, elle se manifeste le plus souvent de manière subaiguë chez des hommes de plus de 50 ans, sous forme de masse ou d'agrandissement diffus des organes atteints. L'aspect histopathologique est celui d'une infiltration lymphoplasmocytaire à prédominance de plasmocytes IgG4 positifs et d'une fibrose progressive. Ses caractéristiques cliniques et radiologiques peuvent rendre difficile la distinction avec un processus tumoral. La maladie répond bien à un traitement systémique de glucocorticoïdes, avec toutefois un haut taux de récidives après l'arrêt du traitement. Immunoglobulin G4 related disease (IgG4-RD) has been recognized since early 2000s as an entity comprising a set of inflammatory diseases with common histopathological features. The disease may affect almost all organs and tissues, and often occurs in a subacute fashion in males over 50 years as a mass or diffuse enlargement of affected organs. The histopathological appearance is characterized by a lymphoplasmacytic infiltration with predominantly IgG4-positive plasma cells and progressive fibrosis. Its clinical and radiological features can make the distinction with a malignancy difficult. The disease responds well to systemic glucocorticoids however with a high rate of recurrence after treatment discontinuation.

Empirical evidence drawn from the economic literature points to a low level of competition in the retail petrol market. Similar evidence can be found for the Spanish market. In fact, both Spain’s antitrust authority -Comisión Nacional de la Competencia- and its energy regulator -Comisión Nacional de la Energía- have recently initiated disciplinary proceedings against the majors on the grounds of suspected price manipulation in the retail petrol market. They are accused of cutting retail prices on Mondays so as to distort the rank position of Spain in European Union statistics in a practice that has received the name of the Monday effect. Here, we analyze this effect by constructing a database that includes daily retail prices for all petrol stations in Spain in the period 2009-2012, and a more detailed database for the city of Barcelona in 2013. Our estimations confirm that: 1- in 2011 and 2012 prices fell on Mondays at retailers branded by majors; 2- prices were unchanged at stations in our two control groups; 3- prices were also seen to fall when a more detailed analysis was conducted, and this price cut was also found in 2013. In short, one more indicator of collusion in this sector and … one more lie.
