'Average overrun for Games since 1960 is 156% in real terms' [1]. On the whole, costs of hosting Olympic Games is a net-negative for most cities. I think it isn't as popular as it once was in attracting tourists; soccer world cups are probably better for that. Given that this is the case, they should just fix one host city/country and host the Olympics only there. It will save unnecessary expenses, especially for developing nations such as Brazil.
