Rio may be in an economic hangover when the Olympics party is over

350,000 spectators from around the world have flocked to Rio for the Olympic Games.

But many believe that's not enough to pull Brazil out of the longest recession in its history.

The Games have been estimated to cost Brazil at least $4.6 billion, which is less than the cost of the London 2012 and Sochi 2014 Olympics.

But, it is still a lot for a country that has been in an economic recession since the 1930s.

Local hotels and airlines are expected to get a boost from visitors during this time, but these short-time benefits are being overshadowed by larger issues.

Unsold tickets, crime and environmental concerns have all plagued the games in Rio.

Meanwhile, the impact of the Zika virus remains a wildcard, and the country's president and political hierarchy have been in turbulence for months.

One benefit to Rio is the addition of $7.1 billion in new infrastructure, which includes road and subway expansions as well as new sports complexes.

There is hope that Brazil will have a boost in tourism in the years after the Olympics end.

But Greece remains a cautionary tale after its economy collapsed following its hosting of the Games in 2004.
