If Hotelling's Main Street were circular with no 'end-point', but all else remained the same as the 'straight line' model you have studied (so two firms choose the respective locations given the price set by the government), which of the following is the correct statement about this game's Nash equilibria in locations? There is no Nash equilibrium. In any Nash equilibria, the two firms locate on top of each other. In any Nash equilibria, each firm takes a location different from the other's. Any combination of two locations is a Nash equilibrium
