Résumé

The objective of this project is to propose an economic screening to the fuel retail market through two stages: application of global and local Gaussian correlation. The method is able to identify whether there is evidence of cartel formation given retail and wholesales prices in the relevant market. It can also suggest periods when collusion is more likely to have occurred. We use the method for the city of Recife in the northeast of Brazil. We present some generals results to other 546 municipalities in gasoline retail for which data is available.
