Want to know where you'll spend and where you'll to save? Each year, consulting firm Mercer carries out its Cost of Living Survey and compiles a ranking of the world's most expensive cities. Mercer compares 214 cities across the world, looking at the costs of housing, transportation, household goods and entertainment. The results may surprise you.
