In this paper, we intend to contribute evidence in regard to going public financial impact and thus motivation on a sample of mature companies that launched an IPO at the Warsaw Stock Exchange between 2005 and 2015. First, we review recent literature focusing on financial and non-financial consequences of an IPO. Next, we use fuzzy sets and fuzzy reasoning to define a “mature” company and assess financial consequences of going public. Our main conclusion is that the majority of Polish mature companies use an IPO as a channel how to raise capital and accelerate their investments and growth. This contradicts many previous empirical studies highlighting that the main motivation of mature companies to go public is to use the capital raised within an IPO to rebalance their capital structure.

“…Severe knowledge shortages put pressure on the integration of any available information item. It means that knowledge items of different levels of subjectivity and nature must be taken into consideration in order to develop the best possible model of a unique task under study [9]. However, any efficient integration of such knowledge items of different origins requires common sense reasoning (see, e.g., [10][11][12][13][14][15][16][17]).…”

Analysis of Sustainability Decision Trees Generated by Qualitative Models Based on Equationless Heuristics

Sustainability processes are complex and therefore ill-known, inconsistent, and subjective, and must be studied despite a shortage of information. It is prohibitively difficult to study them on quantitative levels using quantitative methods. The presented qualitative approach enables us to solve these issues. There are just three values used to describe the qualitative variables and their derivatives, plus/increasing, zero/constant, and negative/decreasing. An n-dimensional equation-less qualitative model is a set of pairwise relations. Such relations represent a shallow knowledge of the sustainability systems being studied. The solution of the qualitative model is a set of scenarios. The behaviour of this model is described by all of the possible transitions among these scenarios. A decision maker can easily compile a decision tree if he/she knows all of the possible transitions. The generated tree can be evaluated using traditional methods if all of the relevant probabilities are known. Otherwise, some heuristics are used to evaluate the best decision.
