Well, with more time, I do think these suggestions are better served as opportunities. So I'm not sure we need to include them. The basic idea is the same as the "Tallest Building", i.e. as soon as someone else builds it, you lose the effect of your building. Works with Olympic Parks of which there are a lot all around the world and World Exhibition Halls were a big thing in the 19th century and still exist today (List of places).
Oh, you're talking of effects? Either have a complete system where there's one building for every yield (Tallest Building -> Production, Olympic Games -> Culture, World Fair -> Gold, ... , +20% in city) or have them as happyness boosters. But I'm leaning more and more to make them opportunities, it's a much more elegant system than having another building to build and cluttering our city interface. Also the rewards can be adapted, as headcase demosntrated with the Olympics above...
