Opis:: This chapter contains analysis of questionnaires data base which was built by selecting one of several qualitative characteristics formulated with relation to each of the issues included in the questionnaire. The subject of examination is a set of multi- profile elements. In the initial part of the chapter, a method of division of such a set of objects into subsets including similar objects has been presented. Similarity of the objects is the basis for describing a function of distance between them. Then, by analyzing values of distance function, the entire set is divided into clusters. Research premise is executed in two sections. By calculating the distance between characteristics of analyzed phenomenon, which are represented by items in the questionnaire, a group of similar features - or lack of relationship between features - are determined. Second facet of the analysis consists in determining the distances of multi-profile objects from fixed standards, and division of the set of objects into homogenous layers. In paragraphs that follow, results of research conducted using the above method, and concerning changes in economic situation of Polish construction industry in 1993 - 1997 are shown. On the basis of the questionnaire data from the Institute of Economic Development and obtained from construction enterprises, mutual relationships between measures of economic situation have been examined. Moreover, changes in economic situation of construction enterprises in comparison to their distance from standards of economic situation have been analyzed, both in the entire population of enterprises and in two sectors of construction industry: private and public.

Opis:: This paper is focused on informal relations between state authorities and business, which exist in a peculiar Belarusian economic system, where the competition remains restricted, and the public sector based on large companies continues to play a crucial role. The author argues that the Belarusian public authorities have developed a broad set of informal rules which allow them to extract resources from small and medium private enterprises (SMEs) and control the expansion of the private sector He also argues that as long as informal extractive institutions designed and maintained by the state remain in place, the improvement of formal business regulations alone will not produce the expansion of the SME sector In author's opinion, an extra-legal extraction of funds and informal discrimination against small and medium private enterprises are embedded in the logic of the centrally planned economy, which Belarus has preserved after the fall of the Soviet Union. This dissertation may also help to understand how SMEs operate in many other economies of the post-Soviet area and what obstacles to the development they face.

Opis:: The problem of imperfect knowledge became crucial issue for many applications including economic applications. Rough set theory, proposed by Z. Pawlak (1982) is one of the existing approaches to understanding and manipulation of imperfect knowledge. This theory has attracted many researchers and practitioners all over the world, who contributed essentially to its numerous developments and applications. The aim of this chapter is to present preliminaries of rough set theory (including information systems and decision tables, indiscernibility, lower and upper approximations of sets, reducts, patterns) and application of rough set methods to the construction industry data analysis with respect to the economic conditions. We present some methods based on rough set approach for solution of the following problems related to the analysis of such data: - Extracting dependencies between queries in questionnaires. - Searching for relationships between respondent answers and classification. - Extraction of (minimal) relevant subsets of queries predicting with high quality answers for other questions. Characterization of respondent situation changes in the consecutive year quarters. We discuss the results of Computer experiments including also visual representation of the received results.
