I always had this question, and it seems that none of my friends here at my university know the answer. We had this doubt specifically about Brazil, but all non-major countries (outside US, Canada and Europe) can be included in this question. In fact, there are two questions:
1) How the Consulting salaries are calculated outside the Euro-zone and Dollar? Are they always calculated in local currency, or they have to be paired with a major currency?
2) It seems pretty obvious to me that the salaries in Developing countries (Russia, Brazil, Colombia, Egypt, Thailand...) are lower than the ones in America/Europe. But, in average, the salaries are how much % of the salaries in those major areas?
The second question is pretty straightfoward question.
The first one is a little tricky, and the idea is to understand better what will happen to the wages when there are some major swing with the local currency.
If the salary is calculated locally, a local currency appreciation will increase my real wage when compared to the ones in the US, and my purchase power (in terms of imported products) will increase.
In the other hand, if the salary is calculated as a fixed % of the salaries in the US, in dollars, a local currency appreciation will decrease my real wage in terms of local products.
