-2, and if column choose low, row will also choose high because 6>3. The Beach Location Game You (Y) and a competitor (C) plan to sell soft drinks on a beach. Consequently, some authors refer to it as a âCournot-Nash equilibriumâ (or as a âNash-Cournot equilibriumâ). Nash equilibria in behavioral strategies are de ned likewise: a pro le of behavioral strategies is a Nash equilibrium if no player can achieve a higher expected payo by unilaterally This tragedy of the â¦ So this is definitely not a Nash equilibrium.
