a very basic understanding after Baldwin and Wyplosz
Teorētiski šis ir attiecināms uz jebko. Kamēr vien formula darbojas. Un darbojas tā vairākumā gadījumu. Par cilvēcīgumu nerunāsim, par ētiskumu arī ne. Turklāt šis princips ir lieliski izmantojams jebkuru cilvēcisku attiecību analīzei.
Laipni lūdzam economic reasoning pasaulē :)
La courbe des rendements décroissants as well as diminishing returns can explain quite well why young, but well-off people tend to produce less significant returns as their mates who come from poorer countries. This is also true if we look at the rate of investment in one person. While you have almost next to nothing, even a small encouragement could boost your activities to a very important level that otherwise you could never have attained. Still, as you receive more and more, you tend to give back less and less. Or you just need much more to ensure the same growth as before.
On the other hand, this reasoning applies as well to human growth as such. As you are very, very young you tend to have important progress even with the smallest amount of new information. You are like a white sheet of paper with enormous capacities just because you still have very little information. All you need is to manage what you have and as your capacities are greater than the amount you have to internalize, you grow not by hours but by minutes. As you grow older, you have more information already internalized and thus you have to have a larger amount of capacities to ensure not only the same amount of incoming information, but also its adaptation to already existing system of the previously acquired knowledge. Unfortunately, the growth of capacities is not proportional to the amount of newly acquired information. Therefore it is clear that as you grow older you learn slower just because you have to not only learn but also adjust the received data.
A logical conclusion follows: the more you are mature, the less proportionally performing you are. If you would compare the outputs of an intelligent youngster with those of a mature person (presuming that he/she being a youngster had the same capacities as the first individual mentioned), you would certainly find that the young one proportionally over performed the older one. This is of course true only after the breaking point, that is, the point after which the proportional growth of acquired information did not give the same quality growth of performance.
Finally one could presume that as we grow older, we get less efficient. This is certainly true, but as to attaining a certain level of capacities is generally more important than the proportionality of the information gained and afterwards the knowledge (and skills) acquired, highly educated people are valued more than those with just college degree.
