[edit]This looks like just a display bug when the policy is first selected. It fixes itself on the following turn.
Selecting Monopolization in my latest game made my happiness worse. In the happiness dropdown, it added a "+1 extra happiness per luxury resource (30)" line but also changed the "difficulty" happiness modifier from +11 to -8. Furthermore, even if those two changes were supposed to happen, the two lists (the sums of all the happiness mods and all the unhappiness mods) now don't add up to my actual new displayed happiness.
