The result also supports the assertion of Economides (2010). If network operators impose delay to specific standard lane, all service providers will try to use priority lane even they pay additional cost. This is called as ‘prisoner’s dilemma’ that ASPs and CPs are provided the same service as before, with increased cost. It leads to reduce welfare of ASPs, CPs, and even consumers. As seen from Table 5, if ASPs chose the strategy set (SL, SL), both of them could make more profit. This is the case of ‘prisoner’s dilemma’ that players cannot change their strategies because of the fear of competitor’s deviation even though they know that both of them can have better payoff by changing their strategies.
