There are two groups, rich and poor. Both are willing to pay a premium to live with the rich. Poor people are always willing to pay a constant premium of $18 per square meter. Rich people's willingness to pay a premium grows with the fraction of rich people in the neighborhood and is given by P=1+ 20x where P denotes the premium per square meter and x the fraction of rich people (e.g., for 50% use 0.5 etc.). Only consider the fraction of rich people ranging between 50% and 100%. If the neighborhood starts at 52% rich people the equilibrium will be at 85% rich there's no equilibrium 100% rich none of the above Integration and Segregation (3 pts) There are two groups, rich and poor.
