List of countries by GDP (nominal)
Gross domestic product (GDP) is the market value of all final goods and services from a nation in a given year. Countries are sorted by nominal GDP estimates from financial and statistical institutions, which are calculated at market or government official exchange rates. Nominal GDP does not take into account differences in the cost of living in different countries, and the results can vary greatly from one year to another based on fluctuations in the exchange rates of the country's currency. Such fluctuations may change a country's ranking from one year to the next, even though they often make little or no difference in the standard of living of its population.
BRIC
South Korea is one of the world's most highly developed countries and including it with developing countries like the BRICs is not deemed correct. However, commentators such as William Pesek from Bloomberg argue that Korea is "Another 'BRIC' in Global Wall", suggesting that it stands out from the Next Eleven economies with its BRIC-like growth rate, despite its Human Development Index being higher than some of the world's most advanced economies, including France, UK, Austria, Denmark, Finland and Belgium. South Korean workers are the wealthiest among major Asian countries, with a higher income than Japan and the strongest growth rate in the OECD. More importantly, it has a significantly higher Growth Environment Score (Goldman Sachs' way of measuring the long-term sustainability of growth) than all of the BRICs or N-11s. According to the IMF, South Korea's GDP measured by purchasing power parity is already larger than Canada and Spain. In terms of GDP per capita (PPP), South Korea overtook Spain in 2010. According to Citibank, South Korea will continue by overtaking Germany, Britain, Australia and Sweden by 2020, surpassing Canada, Switzerland, Netherlands and Norway by 2030 and taking over the United States by 2040 to become the world's wealthiest major economy. While measuring the South Korean economy by nominal GDP is inaccurate as the South Korean won is artificially kept low to boost exports, IMF predicts South Korea's nominal GDP and GDP per capita will surpass Spain in 2015. Economists from other investment firms argue that even when measured by nominal GDP per capita, South Korea will achieve over $145,000 in 2040, surpassing the United States, suggesting that wealth is more important than size for bond investors, stating that Korea's credit rating will be rated AAA sooner than 2050.
