President Trump wants Congress to fund a border wall; the Democrats, who now have regained control of the House of Representatives, do not want to fund a border wall. Which side will “swerve” first? The Game of Chicken, along with the Prisoner’s Dilemma and the Battle of the Sexes, is one of the ways in which this political conflict can be modeled. Here is the Wikipedia entry for the Game of Chicken; here is a memorable example of Chicken from the movie “Footloose”. Update (6pm): As I replied to Kathy H. in the comments section, I find it fascinating that in this particular case the intransigence of both sides is due to their moralizing of the border wall, which suggests an inverse relationship between the ability to reach a pragmatic compromise and the strength of one’s moral convictions!
