The liberalization of the German Markets for postal Services which have been realized with the beginning of 2008 was politically combined with the introduction of minimum wage legislation. This minimum wage increases the labour costs of the competitors without reaching the cost level of the incumbent. The industrial economic analysis Shows that the minimum wage is able to prevent market entries. But the minimum wage legislation is under attack by administrative Courts and some political Parties. Hence, it is possible that the minimum wage for postal services will be shortly abolished. An alternative to the minimum wage Gould be the using of existing economies of scale and scope by the incumbent to squeeze the competitors out of the market.
