Suppose US$1 = €0.7809 in New York and US$1 = €0.7793 in Paris. How can foreign exchange traders profit from these exchange rates? What actions can they take that may result in the same dollar/euro exchange rate in both New York and Paris? Please limit your response to one or two reasonably-sized paragraphs.

If a Dollar is worth $ 0.7809 Euros in New York, and $ 0.7793 Euros in Paris, the way in which foreign exchange traders could obtain an economic profit through this difference would be by buying Euros in Paris, and selling them again in New York. Thus, they would obtain $ 0.016 of profit for each Euro traded in the market, with which, for example, if $ 1,000,000 of Euros were traded, a total profit of $ 16,000 would be obtained. In turn, trading the same amount in both Paris and New York, traders would not make any profit, equating both exchange rates.
