Speaking to a crowd of more than 1,000 students and other members of the University of Texas at Austin community, Dean Tom Gilligan used colorful charts and detailed graphs to explore trends in prosperity and poverty around the world. He explained how gross domestic product (GDP) is used as a measurement tool, how “real GDP” and “GDP per capita” are calculated, and how these figures are used to compare economies across regions, across populations and across the world.

  • Instructor Note: The size of the circle indicates relative population. Italy has a higher survival rate than the U.S. even though per capita income is larger.
  • GDP per capita today varies enormously among nations
  • Instructor Notes: Important Points: GDP per capita In 1 – 1500 AD—Was about $400–$600 Today, richest countries are over 50 times as wealthy as the poorest countries.
  • Instructor Note: Important Points: In 1950 South Korea and Nigeria had the same per capita real GDP In 1950 Argentina was considerably richer than both Japan and South Korea.
  • Instructor Note: While the diagram clearly indicates that higher investment rates are correlated with higher per capital income, an interesting question is also suggested: The United States and Brazil have similar investment rates, but the U.S. has a much higher per capita income. Two ideas come to mind: (a) The U.S. has been growing rapidly for a longer period of time so Brazil is catching up, and (b) capital may be more productive in the U.S. because of better technology.
