Ireland is one of the few countries where GDP and GNP differ dramatically. Using GDP per person, Ireland has the third highest income per person in Europe. An article on the Financial Times website states that: "With GDP being about 20 percent larger than GNP, Irish people appear (when using GDP per person) to be richer than what they feel they are." Source: Valentina Romei, "Ireland Is the Wealthiest Economy in Europe..or Not," ft.com, May 13, 2015. Briefly explain the author's reasoning. O A. The prices that Ireland charges for its goods and services must be higher than the rest of Europe, which explains why the Irish people appear richer than they feel they are. O B. A significant portion of production in Ireland is by foreign-owned firms, which makes the Irish people appear to be richer than they feel they are. O C. Most of the increase in the value of production in Ireland must be due to inflation, making the Irish people look richer than they feel they are. D. Many Irish workers have jobs in other countries, which makes the Irish people appear richer than they feel they are.
