Abstract: Summary Since the German Telecommunications Market was liberalized in 1998 the prices for call-by-call have declined continuously. In the short-run we observe significant and systematic price movements. These can be qualitatively reproduced in a dynamic game theoretic model with ill-informed consumers. In our model the sellers set their prices in each period simultaneously. The demand depends only on the probability that the consumers know the prices of the present period or that they only know the prices of the previous period. In our model we find incentives for the sellers to deteriorate consumers information by often changing prices.
