Abstract
The analysis of cyclic processes in the financial markets has drawn attention to the possibility of market saturation. It should be noted that overproduction is carried out in open markets, and saturation – in closed markets. Due to saturation, profitability of investing in closed markets increases and thus price bubbles are formed. The increase in profitability and emergence of price bubbles are forms of expression of a new economic paradox. The analysis of saturated economic systems started only in the last decade. This article contains modeling of saturated economic systems, supported by the newly-created "Logistic analysis tool". The tool is based on the model of logistic interest, developed in the last decade (S. Girdzijauskas, 2002).
