Since 2008 – i.e. for 15 years now – ecostra GmbH has conducted an annual survey of international brand manufacturers who are tenants in outlet centres in Europe. Since 2012, this survey has been carried out in cooperation with the French research institute magdus. By now, the report is regarded to be "the" benchmark for the European outlet industry. The results are printed in detail in the so-called "Outlet Centre Performance Report Europe" (OCPRE), which can be obtained from the ecostra-Webshop.
