Since May 2008, German law has permitted placing a “GMO-free” label on food products within the framework of GMO regulations (EC 1829/2003). It is found in the market along with organic food labels that similarly require the absence of GM products and with labels that designate regional qualities. This paper analyzes the retail price dynamics of organic, GMO-free, and conventional milk after the introduction of GMO-free labeling in Germany. Using weekly data of the GfK consumer home scan, data from German milk sales in the early period of its introduction in 2009 and 2010 were analyzed in a vector error correction model.
