Two competing firms are choosing where to locate new stores. First, Firm 1 decides whether to locate in Downtown (D) or Uptown (U). After Firm 2 sees the decision Firm 1 made, Firm 2 chooses Downtown or Uptown. Uptown is a more profitable location than Downtown; a firm choosing Uptown earns a profit of $700,000 if the other firm also chose Uptown, or $1,300,000 if the other firm chose Downtown, while a firm choosing Downtown earns $400,000 if the other firm also chose Downtown, or $900,000 if the other firm chose Uptown.
