The aim of this paper is to assess whether mergers of companies in the Czech Republic affect the profitability and returns of merged companies in the period of three years after the merger. The analysis is based on the sample of over 300 Czech companies implementing mergers in 2001 – 2010. This sample was created using data from the Trade Bulletin and Trade Register of the Czech Republic. The analysis used basic statistical tests verifying the statistical significance of the particular explored indicators of merging and merged companies three years after the merger in relation to the same indicators at the moment of merger. The explored indicators were net earnings after taxes (EAT), return on assets (ROA) and return on equities (ROE). The period of three years after the merger was chosen due to the reduced influence of some accounting methods requiring revaluation or exclusion of some assets from the balance sheet of the merged company.

The article is concerned with the critical analysis of some aspects of the methodology and language theory on which Mluvnice současné češtiny [Grammar of Contemporary Czech] (Cvrček et al. 2010) is based. First, the statement by the authors of Mluvnice současné češtiny concerning the character of the description of language and its relationship to reality is criticized. Specifically, it is argued that the use of corpora does not lead to the recognition of “real” language properties, since every description of reality is an interpretation. The idea concerning the representativeness of corpus is also called into question. Furthermore, a serious statistical deficiency is revealed. Namely, it is demonstrated that the assignment of difference expressed by a percentage as significant (or non-significant) is unacceptable – the results should be interpreted using common statistical methods. Next, fundamental problems of the semantic theory (naive mentalism) used in Mluvnice současné češtiny are discussed. A rather different view of a semantic analysis based on experimental methodology is mentioned as an alternative to the traditional approach. Finally, the langue-parole dichotomy, viewed by the author as a residue of Platonism, is argued to be inconsistent with the empirical methodological approach adopted by the authors of Mluvnice současné češtiny.
