In this chapter, I present a systematic overview of the market outcomes for
classical oligopoly games. This study contains six games: pure quantity competition,
pure price competition as well as price and quantity competition, each with
simultaneous and sequential moves. I present equilibrium prices, quantities and profits
for each game. In particular, I present the mixed strategy equilibrium of the
simultaneous price and quantity competition. This equilibrium was found by Gertner
(1986), but remained unrecognized so far. From a comparison of market outcomes, I
can classify situations where the choice of decision variable(s) and timing gives
strategic advantages.
Keywords: Decision variables, judo game, mixed strategy equilibrium, price,
