The study looked at how Dutch businesses decide which currency to use in international trade. They used data from 1987 to 1998 and found that when demand for Dutch goods drops in a foreign market, they are less likely to use their own currency for invoicing. Countries with strong banking sectors and high world trade shares tend to use less Dutch currency. If a partner country has high inflation, Dutch currency invoicing increases. The depth of a currency's foreign exchange market, the partner country's world trade share, and EU membership influence which currency is used in trade.
