The 'Arbeitskreis Volkswirtschaftliche Gesamtrechnung der Länder' now publishes figures concerning the value added in Germany. Formerly the Statistische Bundesamt had this assignment. Some corporations have plant locations in the new Länder as well as in the old Länder. The employed method for splitting-up the value added produce by these corporations might lead to an underestimation of the overall value added produced in the new Länder. However, an estimation using the firm panel of the IAB shows that the East German productivity gap for manufacturing is overestimated by maximally two percentage points. Still in sectors that are dominated by multi plant corporations this effect is stronger. All in all the East German productivity gab is overestimated by maximally three percentage points.
