Mirza Samkharadze

The work shows the following: investment is a dimensional and temporary category.

Investment act (activity) that can be a real investment in a particular area, might not be a real investment in other area. Similarly, investment act that is investment in a particular time, might not be a real investment in another time.
Growth of international economic contacts causes acceleration of processes and large-scale equalisation of life standard in developing world.
If benefits of alternative investment are defined as time functions, the determination of the most profitable investment strategy will depend on the choice of observation period.
High investment activity leads to better macroeconomic indicators in the given economy: fast growth, low unemployment level and inflation.
The central factor of short-term fluctuation quality of main macroeconomic indicators is a multiplication measure. There is a regularity between short-term fluctuations of unemployment level and real domestic product. Oucken law represents a private case of regularity that will function only in the US economy.
