- ItemAlter Ego Only Four Times? The Case Study of Business Profits in the Visegrad Group(Technická Univerzita v Liberci, ) Valášková, Katarína; Gavurová, Beáta; Ďurana, Pavol; Kováčová, Mária; Ekonomická fakultaThe paper studies a new point of view and the approach to profit as an inherent part of business finance as well as a symbol of every healthy economy. The fundamental function of the profit is a stimulus; it means initial motivator of the business activity. The profit provides core resources for survival at the business start and after the stabilization, it is the synonym for progress. The aim of this paper is to detect significant change-points in times series of EBITDA during the analysed period in every country of the Visegrad Group to recognize the progress years in the monotonic development. We use a method of homogeneity test of time series that delivers significant robust results. We observe the variable EBITDA to eliminate different tax, interest and depreciation policies of these emerging countries. The original research of this article is based on empirical results of business profits of the sample of 3,853 enterprises covered by the broad theoretical review. Firstly, we identify missing values; and detect the outliers by Z-score and Grubbs test. EBITDA of 1,058 Slovak enterprises, 688 Czech enterprises, 1,376 Polish enterprises and 731 Hungarian enterprises is analysed during the period from 2010 to 2018. We eliminate the inconsistent observations and construct average values of EBITDA. Secondly, we prove normality by Jarque-Bera test, and support it by Shapiro-Wilk test, Anderson-Darling test, Lilliefors test to deliver reliable results. Thirdly, we find an independency of distribution that confirm randomness by the Box-Pierce test. And finally, we identify the years that affect heterogeneity of EBITDA in the countries of the Visegrad Four. We uncover some really surprising results. For all countries in the Visegrad Four, the year 2013 is detected as a change-point at a significance level of 0.05. This significant year shifts EBITDA between two homogeneous series with corresponding central lines and recognizes the similar annual development within the groups. In addition, we discuss the results to the areas and factors affecting the business risk. The adjustable area represented by the business dynamism has no significant impact on the development of EBITDA. The uncontrollable macroeconomic factors such as a GDP, unemployment rate, inflation rate, average monthly gross wage, and Ease of doing business index demonstrate the same development of Slovak, Czech, Polish and Hungarian enterprises. We connect our gained results to the undisputed influence of these factors and its derived components on monotonic development of EBITDA. Despite the fact, that the countries are not economically interconnected as they used to be in the past, in has to be underlined that their mutual relations are still very narrow and close and that might be the reason, why identical results are achieved in the countries with divergent development.
- ItemThe Influence of Competitiveness on Start-up in SMES Segment(Technická Univerzita v Liberci, ) Dvorský, Ján; Čepel, Martin; Simionescu, Mihaela; Ďurana, Pavol; Ekonomická fakultaThe paper aims to identify important factors for competitiveness (CF – Competitive environment, FF – Narrower business environment), which impact start-up in a segment of SMEs. In regards to the defined aim, survey-based research was conducted with enterprises operating in the SME segment. Three 312 enterprises in the Czech Republic and 329 enterprises in the Slovak Republic were approached during this research. The multiple linear regression was used: (a) to quantify the relationship between the variables, (b) to identify the most critical indicator of QBE, and also to verify the scientific hypothesis. The competitive environment has a significant impact on the quality of the business environment in the SME segment. The authors found that the selected factors (CF and FF) were statistically significant. The competitive environment (CF) has a greater impact on the quality of the business environment than the narrower business environment (FF). Human capital represented by employees and the adequacy of supplier prices are indicators that have a significant impact on the quality of the business environment in the SME segment. The most critical CF indicator is that the suppliers of SMEs demand reasonable prices for their products and services. On the contrary, the least significant indicator is the intensity of competition in the sector. The most important indicator of a narrower business environment is the contribution of employees in achieving business goals. On the opposite, the least important indicator of a narrower business environment is the support of suppliers to meet the business goals of SMEs.
