Opis:
This paper investigates irregularities in financial statements by applying the Beneish and Roxas models to Polish firms listed on the Warsaw Stock Exchange from 2015 to 2020. The total sample included 110 observations. The sample comprised companies that had received an adverse or disclaimer opinion by the auditors, but had not been fined by the Polish Financial Supervision Authority (KNF Board). The control firms were selected based on the industry as selected by the standard industrial classification code and on the financial year, with minimizing the difference in the size of total assets. The results indicate that the Roxas model revealed greater accuracy than the Beneish model on the tested sample. The use of logistic regression allowed a modification of the Beneish model to align it with the conditions of the Polish market. The modified Beneish model showed greater accuracy for the tested sample and companies fined by the KNF Board.

Opis:
Aim/purpose - This paper analyzes the role of Benford's law in the detection of earnings management in Poland. Previous research that uses Benford's law does not split the sample into a fraud and a control group; however, this method is used in logistic regression and data mining analysis. Design/methodology/approach - The sample comprises 126 observations of Polish non-financial companies listed on the Warsaw Stock Exchange for the years 2010-2021. The author uses first, second, and first-two digits analysis as a proxy for earnings management detection. Findings - The results indicate that fraudulent companies have different deviations in the digits than control firms. Accordingly, the statistical test results indicate that control companies have weaker conformity with the Benford distribution than fraudulent companies. Research implications/limitations - The study sample is limited to 126 observations, which is due to the small number of listed firms that received a monetary fine from the Polish Financial Supervision Authority (UKNF Board) for violation of IAS/IFRS principles related to their financial statements during the study period. Originality/value/contribution - The author offers a significant contribution to the accounting literature by proposing the separation of fraudulent and control observations in Benford analysis due to differences in the deviations of digits. Also, analyzing the full sample may lead to the identification of inappropriate areas for further auditor analysis.

Opis:
This paper presents the influence of the COVID19 pandemic on gross domestic product (GDP) per capita for the 27 countries of the European Union. A panel model with fixed effects was applied to a dataset from 2010 to 2020. The analysis covered 13 independent variables, including nine related to the telecommunications market, and assessed their impact on GDP per capita. A variable related to the number of COVID-19 deaths per one thousand inhabitants was then added to the model. The results showed that COVID-19 is a significant factor and is negatively correlated with GDP per capita. The analysis described in the article has also shown that the importance of the ICT sector increased during the pandemic, i.e. the household broadband Internet variable became statistically significant.

Opis:
In this article, we study the substitution between leasing and bank loans in financing the investment of small companies. The analysis is based on financial information about Polish companies listed on NewConnect, which used financial leasing in the period of 2012–2016. We argue that leasing and bank loans are the substitute in financing the investment of small companies. We estimate the probability of financial leasing and its size using the tobit and logit models. We find that financial leasing and bank loan, for Polish small companies, are complementarity. Our empirical results indicate that financial leasing and bank loans are complementary sources of financing investment in fixed assets. Also the higher the usage of financial leasing, the higher the likelihood that the enterprise is indebted because of long-term bank loan – complementarity.
