Purpose – Environmental degradation resulting from human activities may adversely affect human health in multiple ways. Until now, policies aimed at mitigating environmental problems such as climate change, environmental pollution and damage to biodiversity have failed to clearly identify and drive the potential benefits of these policies on health. The conducted study assesses and demonstrates how specific environmental policies and instruments influence perceived human health in order to ensure input for a data-driven decision process.
Design/methodology/approach – The study was conducted for the 2004–2020 period in European Union (EU) countries with the use of dynamic panel data modeling. Verification of specific policies’ impact on dependent variables allows to indicate this their effectiveness and importance. As a result of the computed dynamic panel data models, it has been confirmed that a number of significant and meaningful relationships between the self-perceived health index and environmental variables can be identified.
Findings – There is a strong positive impact of environmental taxation on the health index, and the strength of this relationship causes effects to be observed in the very short term, even the following year. In addition, the development of renewable energy sources (RES) and the elimination of fossil fuels from the energy mix exert positive, although milder, effects on health. The reduction of ammonia emissions from agriculture and reducing noise pollution are other health-supporting factors that have been shown to be statistically valid. Results allow to identify the most efficient policies in the analyzed area in order to introduce those with the best results or a mix of such measures.
Originality/value – The results of the authors’ research clearly indicate the health benefits of measures primarily aimed at improving environmental factors, such as environmental taxes in general. The authors have also discovered an unexpected negative impact of an increase in the share of energy taxes in total taxes on the health index. The presented study opens several possibilities for further investigation, especially in the context of the rapidly changing geopolitical environment and global efforts to respond to environmental and health challenges. The authors believe that the outcome of the authors’ study may provide new arguments to policymakers pursuing solutions that are not always easily acceptable by the public.

Purpose – This paper aims to verify how the intellectual property (IP) box affects firms’ effective tax rate, growth and innovation activity outcomes related to intellectual property rights.
Design/methodology/approach – Implementing the innovation box regimes into the tax system intends to encourage firms to engage in more innovative activities. In UK, Italy and Poland, the IP box tax relief was introduced in 2013, 2015 and 2019, respectively. In return, companies may reduce their tax rate to increase their investment and innovativeness. With a panel model approach – system GMM and DiD with multiple time periods – it analyses data from the Orbis database for 2011–2019 of 673 firms from the gaming industry in 11 countries and hand-collected data on intellectual property rights protection. The authors study public and private companies from the gaming sector in leading European markets and all three countries that protect intellectual property rights of software (Japan, South Korea, the USA).
Findings – Recent reforms enable gaming companies to use preferential tax treatment for IP-related income and significantly impact a firm’s revenue growth.
Practical implications – Nevertheless, European gaming firms require time to leap the gap to the growth and innovativeness of countries that protect software.
Originality/value – The authors show that the IP box stimulates gaming firms to protect IP via wordmarks, figurative marks, trademarks and software patents that bring effects in five years. Despite the critics against IP box, the authors prove its lagged efficiency, especially in profitable and larger firms.

Purpose – The article investigates the patterns of asset impairment recognition in search of signs of “big bath” earnings management practices across an internationally diversified sample of public companies. It also elucidates the incentives that may underlie such practices and explores possible safeguards embedded in the existing corporate governance mechanisms.
Design/methodology/approach – The article applied static panel and binary logit models to an international firm-level panel dataset of 1045 public companies observed between 2003 and 2018.
Findings – Our empirical results suggest that recognition of asset impairment has no determinate impact on earnings volatility. Investigating the possibility of “big bath” earnings management practices, the authors found no impact of asset impairment recognition on total senior executive compensation in firms, which pay performance-based remuneration. The quality of corporate governance has appeared to impact the firms’ intertemporal proclivity to recognize asset impairment with those having the more entrenched and
management-controlled boards being more likely to time impairment recognition by delaying it during exceptionally good and exceptionally bad years. While generally unlikely, recognition of asset impairment in a period with a recorded negative operating performance is found to be closely associated with key executive departures.
Originality/value – The article corroborates the salient role of corporate governance mechanisms in shaping the intertemporal patterns of asset impairment recognition. The possible remedies to the phenomenon should be derived therefrom.

Purpose: The article considers country-level governance factors (legal/regulatory system and financial development) and ownership concentration that impact the value of non-financial firms in Central European nations, specifically by describing a study done in Austria, Czech Republic, Germany, Hungary, Slovenia, and Switzerland.

Methodology: A fixed effect panel data regression analysis was applied to a strongly balanced panel data using a collection of six diverse Central European countries’ non-financial firms across the sample period of 2010–2020.

Results: According to regression analysis, the legal and regulatory system as well as financial development have a positive relationship with firm value. The firm’s value rises as the legal and regulatory system improves. Furthermore, the growth of financial markets adds to the firm’s value. However, our study reveals a negative relationship between ownership concentration and firm value, which indicates that ownership concentration is too high to allow for effective supervision, implying that more ownership concentration lowers firm value, as the expropriation theory suggests.

Originality: The study examines the value of a firm by incorporating both country- and firm-level factors, which broadens the current literature’s insight.
Implications: Overall, our findings add to the literature on the value of non-financial firms by providing new significant information. Some of the recommendations may be beneficial to the long-term success of non-financial companies.

Purpose: The article evaluates the associative relationship between international supervisory board experts and foreign ownership, along with the experts’ influence on the financial and operating performance of firms. The study was based on data collected for 257 companies listed on the Warsaw Stock Exchange in 2010–2015.

Methodology: The dataset was built as a panel, and then generalized least squares regression models with a fixed or random effect were employed to test hypotheses.

Findings: The findings of the study clearly show that the presence of investigated firms in foreign markets positively affects company performance. Moreover, models with dependent variables ROA and ROS show that supervisory board members with foreign experience positively affect profitability indicators of firms that do not operate on foreign markets. The data analyses reveal that international experts are more effective advisors for companies that conduct no business activities on foreign markets. Furthermore, the results show a positive moderate association between the share of international experts in supervisory boards and the share of foreign ownership in the company.

Originality: The article contributes to the understanding of determinants and consequences of the presence of international experts in supervisory boards and company internationalization.

Purpose: This study aims to investigate female top managers’ choice of working capital management
policies and its effect on firm profitability. The theoretical arguments about the effects of working
capital management policies on firm profitability and empirical evidence are often inconsistent.
Additionally, it is likely that the policy choice is closely related to the gender of top managers.

Methodology: Our research sample was all 136 manufacturing firms listed in Indonesian Stock
Exchange during the 2013–2017 period. Following the hypothesis formulation, this study employed
four estimation models tested using panel data regression.

Findings: Female CFOs tend to choose more conservative working capital investment policies.
Moreover, conservative investment policies have a positive effect on firm profitability and mediate
the impact of top female managers on firm profitability.

Originality: Previous literature tends to overlook the role of top female managers in affecting
working capital management policies and the effect of these policies on firm profitability. In this
respect, this study provides insights on the role of the gender of top managers as a factor that likely
explains the choice of working capital management policies in manufacturing firms which, in turn,
affect firm profitability.

Purpose: The purpose of this paper is to examine the relationship between working capital management and firm performance for firms listed on the Indonesian Stock Exchange. Prior works have employed many indicators of the working capital. The results of previous studies, however, have been inconsistent. This study is an attempt to find out the best proxy of working capital in explaining firm’s performance.

Methodology: This study employs regression panels for five measures of working capital to model the data for fifty-four firm-year observations that meet the sampling criteria, covering the time 2010–2014. This study also uses adjusted R-squared as the criteria to select the strongest relationship between measures of working capital and firm performance.

Findings: The findings indicate that all proxies of working capital management met expected signs and statistical significance. Hence, working capital management significantly improves firms’ performance. The proxy of inventory turnovers is the best measure of working capital in explaining firm performance.

Originality: To the author’s knowledge, this is the first study examining the relationship between five measures of working capital management and firm performance in Indonesia or in any emerging markets; hence, this study contributes to the scarce literature on the management of working capital.

Purpose: The article presents the results of a study conducted for the January effect. This anomaly is best recognized in the capital markets. In this case, we fnd explanation of its appearance based on both fundamental analysis and heuristics used by investors. The research focuses on the markets of the European Union enlargement countries of 2004. There are three hypotheses stated in the article: Hypothesis 1: The January Effect occurs in the analyzed markets. Hypothesis 2: The January Effect weakens over time. Hypothesis 3: The January Effect weakens with the development of a market.

Methodology: Three methods verifed the hypotheses: tests of differences, average and median rate of return, and dynamic models paneled with the estimation of parameters and the generalized method of moments.

Findings: The January Effect exists in the analyzed markets. The anomaly weakens over time but, after accession to the European Union, January return rates increase signifcantly.

Limitation: The defnite verifcation was diffcult due to the available methods and data. Further research in this feld is, therefore, needed.

Originality: The originality of the paper stems from the construction of the sample – new evidence from post-communist countries – which became the European Union members in 2004. The next important issue is the period of twenty years after the economic transformation – ten before and ten after the enlargement of the EU.

Purpose: The purpose of this study was to investigate the influence of market structure and market conduct characteristics (such as market concentration, presence of networks operated by global corporations, presence of vertically integrated companies, presence of hypermarket gasoline stations and consumption level) on price-cost margin levels, based on an example of the European Union retail gasoline market.

Methodology: The research applied regression analysis on a panel data set comprising of average monthly price-cost margins for 2012 to 2015, based on the data published in the European Commission Oil Bulletin, and on a set of variables characterizing market structure and market conduct of 24 European Union member state countries.

Findings: The results showed that in the case of retail gasoline markets, higher industrial concentration yields higher price-cost margins with a statistically significant influence of other market structure and conduct factors.

Purpose: The theory of endogenous growth suggests a number of relations between income inequality and human capital. However, empirical evidence in this field is scarce. Therefore, in this paper we aim to demonstrate the existence of interdependencies between income inequality and human capital across OECD countries.

Methodology: We present findings of the endogenous growth theory on the mechanisms linking inequality with human capital. Subsequently, we attempt to verify these links empirically using the regression function estimated by means of the generalized method of moments (GMM). The empirical analysis is based on panel data from 1995–2010.

Findings: The results of the study reveal the existence of a negative relationship between income inequality and health indicators (infant mortality and maternal mortality). However, we did not reach an authoritative conclusion about the relationship between income inequality and quantitative indicators of educational achievement.

Research limitations: Research is limited to the sample of OECD countries. Interdependencies between income inequality and human capital could be captured more clearly using a broader sample.

Originality: This paper presents one of few studies testing the relation between human capital and income inequality. The use of high-quality empirical data on inequality (SWIID data) and the generalized method of moments made it possible to contribute new arguments to the discussion of empirical analyses of these economic categories.

Purpose: The purpose of this research was to analyze correlates of access to, use of and skills with PC and Internet tools with social characteristics such as occupational category, income and other indicators of status.

Methodology: The research reported here presents trend analysis and multiple regression results
based on nationally representative samples of Poles collected in 2003 and 2008. The data are from
the Polish Panel Study (POLPAN) collected by the Institute of Philosophy and Sociology, Polish
Academy of Sciences.

Findings: The results showed that there are lingering disparities in PC ownership and Internet use
by occupational status (employed vs. unemployed) and occupational category. On the positive side,
all groups are more likely to possess a PC or use the Internet in 2008 relative to 2003. The results
further showed sharp disparities across occupational categories for PC skills. For example, while
100% of professionals claimed the ability to receive an email, only 51.5% of farmers attested to
such skill. A regression analysis showed that only PC ownership had a weak positive effect on later
income. Neither Internet use nor proficiency with PCs and the Internet were revealed to have
positive impacts on income after five years. The results of this study challenged the notion of the
digital divide. The analysis showed that, except in the case of access to a PC in the home, which
had a small impact on income growth, PC/Internet use and skills in Poland in recent years do not
have any statistically significant relationship with income. It was concluded that the finding where
two of the three factors are not correlated with income growth is evidence of digital parity or
a growing digital equality among citizens in modern Poland.

Purpose: This research aimed to identify the prevalence and particular characteristics of export-driven growth as opposed to those of the domestic market. It examined how the relative dynamics of export sales vs. domestic sales were affected by internationalization intensity (FSTS), age of the fi rm, early internationalization, size of the firm and industry technological level. Similarly, it examined the impact of sales growth and its direction
(domestic vs. export-driven) on company performance.

Methodology: The analysis was based on panel data from approximately 300 manufacturing firms in the Mazovia region of Poland that were engaged in sustained export operations during 2003 to 2010. Several hypotheses were tested regarding factors affecting the growth dynamics of regular exporters as well as their performance (productivity).

Findings: This research proved that only a small percentage (less than 10%) of fi rms reached the status of regular exporter. Although regular exporters engaged in international operations shortly after their foundation, they formed a distinct category of early internationalizing fi rms. For the management of young, ambitious ventures, achieving regularity in their initial export operations represented a major challenge.

Implications: Regularity of international sales is crucial for export performance, both at the enterprise and country levels. This implies that export promotion efforts should concentrate on growh-oriented firms, specifically to assist them in reaching regular exporter status shortly after initiating sales outside the domestic market.

Originality: The analysis of the internationalization process was expanded by adding the regularity dimension, which has been rarely addressed in the extant literature.
