At the end of WW2 North and South Korea shared the same culture, geography, natural resources, population density, capital stock, level of human capital, productivity of labor and standard of living. However, today the standard of living in South Korea is over 10 times larger than in North Korea. Why is this? What are the ultimate causes of growth?

Labor productivity and institutions. Change in institutions: NK changed to the communist govt and SK changed to a democracy. Workers in SK were given incentives to work so their willingness to work increased. With this increase, it increased the productivity of labor over time. This increased standard of living because when you are producing more, the economy is growing. Both intimate causes of growth contributed to SK's standard of living today. North Koreans have little to no incentive to work and therefore do not contribute to the economy. This has kept them with a smaller standard of living than SK
