The Winter Olympics in Sochi will be the most expensive in history — around $50 billion — but is the investment worth it? According to several economists, the answer is no. Despite the promise of increased tourism and a patriotic boost, hosting the Olympics is rarely a wise investment. While some cities like London have managed to re-purpose their Olympic complexes, many others have not. In places like Athens, where the 2004 Games cost $15 billion and contributed significantly to the country’s debt, costly buildings have been abandoned. Cities will have to choose whether to make history or money.
