The French capital - which was ranked second most expensive last year - is the only eurozone city in the top ten.
The survey compares the cost of common items, such as bread, in 133 cities.
It then tracks whether prices have gone up or down by comparing them to the cost of living in New York, which is used as a benchmark.
Report author Roxana Slavcheva said Paris had been among the top ten most expensive cities since 2003 and was "extremely expensive" to live in.
"Only alcohol, transport and tobacco offer value for money compared with other European cities," she said.
The average cost of a women's haircut, for example, costs $119.04 in Paris, compared to $73.97 in Zurich and $53.46 in Japanese city Osaka.
"European cities tend to have the highest costs in the household, personal care, recreation and entertainment categories-with Paris being a good representative in these categories—perhaps reflecting a greater premium on discretionary spending," Ms Slavcheva said.
The ten most expensive cities in the world are Singapore (Singapore), Paris (France), Hong Kong (China), Zurich (Switzerland), Geneva (Switzerland), Osaka (Japan), Seoul (South Korea), Copenhagen (Denmark), New York(US), Tel Aviv (Israel), Los Angeles (US).
Inflation and volatile currency fluctuations helped drive changes in this year's ranking, with places like Argentina, Brazil, Turkey and Venezuela all seeing a sharp fall in their cost of living ranking.
Caracas in Venezuela, where inflation neared 1,000,000% last year forcing the government to launch a new currency, was ranked the least expensive city in this year's survey.
The price of a cup of coffee in the capital Caracas doubled to 400 bolivars ($0.62; £0.50) in the space of just a week last December, according to Bloomberg.
Damascus in Syria was ranked the world's second cheapest city.
The Economist Intelligence Unit said a "growing number of locations" were becoming cheaper due to the impact of political or economic disruption.
The ten cheapest cities in the world are Caracas (Venezuela), Damascus (Syria), Tashkent (Uzbekistan), Almaty (Kazakhstan), Bangalore (India), Karachi (Pakistan), Lagos (Nigeria), Buenos Aires (Argentina), Chennai (India), New Delhi (India).
