THE BIG IDEAS

, Note: in chapter 1 Big ideas 1-5 were covered in the Microeconomics class.
Big Idea 6: Wealth and economic growth are important
Wealth and economic growth are directly correlated to self-reported life satisfaction. We see that
the things people care about are more accessible in wealthier countries. Examples of those
things are access to medication, sanitary facilities, education, career choice, vacations,
protection against catastrophes. A good example used in the book refers to the ability to pay for
research and measures against contagious illnesses in this example Malaria in the United States
was used. We see that the economic wealth of the United States allowed them to pay for work
done to prevent future contamination.
Another indicator that is often used is the child mortality rate (< 5 y/o). Here too we find that there
is a strong correlation between the mortality rate and the economic welfare of a nation.
Big Idea 7: Institutions matter
“One Apple feeds one person but one idea can feed the world”
Big idea 7 emphasises the importance of innovation. Most countries that are rich have a lot of
physical and human capital per worker, produce eNiciently by implementing the latest
innovations.
Innovation is driven by incentives, the most important institutions that support these incentives
are property right protection, political stability, honest government/low corruption, a reliable
legal system, and a competitive open market.
The book uses an example of North- and South Korea to illustrate the eNect of socioeconomic
systems on a nations wealth. Communist systems do not incentivise innovation while a
competitive capitalist system does. (The results are obvious)
