Outline of Final Research Achievements

In an economy where the growth finally ceases to exist, Ramsey’s conjecture holds that the most patient individuals or countries come to hold all of the wealth. In a perpetually-growing economy, in contrast, it is shown that the adaptability to changes is sometimes more influential than the patience in determining the economic growth and wealth inequality.
Using an overlapping generations model, we have shown that, with the minimum level of consumption, the population growth converts at a certain phase of the development. It is also shown that technological progress influence not only the growth but also the population dynamics. The slow growth makes the population explosion under poverty, the rapid growth causes the low birthrate and aging population under prosperity, and the steady growth explains the typical demographic transition.
