according to the economist.

1) High cost basis, e.g. the cost of hotel rooms
2) A reasonably homogeneous, educated & well salaried population of clients (NYC & DC probably have a much higher income disparity)
3) We are at the edge of the US and a destination point for international travelers.

About that article...not too much guessing to do if you blend a couple of different articles together.

Doesn't make it true just because it's in print. I've hobbied in Vegas NYC and Chicago as well as LA and on a comparative basis they are all more than boston and LA iOS the most expensive

Comparatively speaking...not the k girl community you speak of which is a different kind if service I was basing on gfe type incall not back page or Asian brothel type experience.

Oh well, so much for the myth of the frugal New Englander.

At least we're doing our part to stimulate the economy.

here i was just looking at Visiting Boston   and checking hotels out damn high they are  
and then I really don't know where to visit as such ( what area ?)  

What else is Boston known for?

The article does not imply Boston men are paying these rates.  The majority are not paying over $300/hr which is the average.  I suspect the data is barbell in nature, or at least very lumpy.  And there are numerous segments to the overall escort market in all locales, Boston of course included.

They also adjusted the price based on cost of living. I found Tokyo prices interesting because of the cost of the city. I have found London and Montreal get the most from your dollars or Euros

did you mean "blow a load" figuratively or literally?
