Ensuring fair treatment of investors
In the dynamic world of open-ended investment funds, where investors continuously enter and exit, and in funds with multiple classes of investment shares, a critical issue often goes unnoticed: the revaluation of liabilities from unissued and unredeemed shares. These liabilities, typically left unsettled and unrevalued for extended periods, can significantly skew the Net Asset Value per Share (NAVpS), leading to unfair treatment of different grou…

Return Intentions Under Temporary Protection
This study examines return intentions among surveyed Ukrainian households under temporary protection in Poland through neoclassical, NELM, structural and social network lenses. Using cross‐sectional data (purposive sample; N = 1113) and econometric modelling, we identify three overlapping foundations of return intentions: economic factors (labour market difficulties and financial concerns), structural conditions (institutional and resource contex…
Green FinTech —Methodological Controversies in Research
The vast majority of research in the area of green FinTech indicates the positive impact of the use of digital technologies in finance on the environment. However, preliminary literature studies have revealed serious doubts about the way in which these results were obtained. The paper aims to determine the methodological correctness of research on the assessment of the impact of FinTech on the natural environment. The authors identified three res…
Own or public? Later livelihoods of Ukrainian war migrant households in Poland
This paper presents empirical research on the livelihood resources of Ukrainian households that fled to Poland due to the Russian invasion and reside there long term. Using a nationwide sample of these households and an accurate econometric framework, we investigate the factors influencing the role of income from work, other private resources and public assistance in covering their living costs in exile. Our findings confirm the importance of pub…
Business angels and early stage decision making criteria
How do business angels assess a prospective entrepreneurial firm when they make an investment decision? This article examines a central question that informal venture capitalists have been struggling with for decades: What early stage decision making criteria do investors define and apply to reduce the volume of potential deals to a more manageable size? Based on semi-structured interviews with business angels in an emerging market, we show that …
When all we have is not enough
Although inflation expectations are pivotal variables for central banks, they are not directly observable. Therefore, central banks use qualitative survey results to proxy consumer expectations, and their quantification in this manner is often criticized. In this study, we investigate and identify an optimal quantification procedure for survey results based on a set of regression and probabilistic models. Specifically, we seek to identify the met…
Business angels in the Czech Republic
There is a lack of knowledge regarding the profiles of Czech business angels. In this article, we intend to contribute the empirical evidence in regard to identifying a ‘typical’ business angel profile in the Czech Republic. Using a unique dataset containing survey gained data on informal venture capitalists, we show that angel investors share many of the characteristics reported for well-developed markets. They are usually males, middle aged, wi…
Identifying the impact of external environment on business angel activity
We intend to contribute the empirical evidence in regard to identifying the impact of external environment on the activity of business angels in Czechia. Although prior academic studies have argued that e.g. overall economic growth, capital market, legal structures and the protection of property rights, corruption, innovativeness, the tax rate and labour market policy are the main determinants of the decision-making of business angels in the well…

Modifiable Areal Unit Problem
Research background: One of the issues considered by economists such as Tinbergen (1939), Klein (1946), May, (1946), Theil (1965), Pawłowski (1969), Bołt et al. (1985) was to determine the mechanism of transition between the results of microeconomics and the theory of macroeconomics. As part of this research, Pawłowski (1969) raised the problem of establishing the relationship between microparameters and a macroparameter. In the presented article…
Economic analysis of implementing VMI model using game theory
Research background: The article deals with implementing VMI between the supplier and customer. To assess whether the system will be implemented, the evolution game theory is used. The contribution is based on the limitations of the study of the evolutionary game theory approach to modelling VMI policies (Torres et al., 2014) and its later extension, The evolutionary game theory approach to modelling VMI policies (Torres & García-Díaz, 2018). It …
Short-term Shocks and Long-term Relationships of Interdependencies Among Central European Capital Markets
The article focuses on the problem of interdependences among Central European capital markets. The main aim of this research is to identify longterm interdependences among Austrian, Czech, Hungarian and Polish capital markets and the market of Germany. Additionally, the impact of short-term shocks on these markets is under evaluation. In the first step of the research the interdependencies among the capital markets in the years 1997-2015 were ver…
Multiple Criteria Analysis of European Union Agriculture
The main aim of the article is to analyze differences in agriculture performance across the European Union countries in the years 2010-2013. Special attention was devoted to the results achieved by New Member States. The research was conducted with application of multiple criteria analysis tools: the method proposed by Hellwig and Ward's clustering method. The research was based on the analysis of the World Bank development indicators. It confirm…
Quality of Institutions for Knowledge-based Economy within New Institutional Economics Framework. Multiple Criteria Decision Analysis for European Countries in the Years 2000–2013
The article concentrates on the problem of quality of institutions in the European Union countries in the context of their compatibility with the global knowledge-based economy. The main objective of the article is to evaluate the progress obtained in that field by New Member States of the European Union in the years 2000-2013. The empirical research is based on the following hypothesis: the integration process of Central European countries with …
The Delimitation of Bipolar Metropolitan Area Within the Kujawsko-Pomorskie Region
The objective of the article was to re-define the bipolar metropolitan area within the area of the Kujawsko-Pomorskie region (NUTS 2). Concentration of metropolitan features, as well as socio-economic situations of its communes (NUTS 5) in 2011, and also the dynamics of communes’ development in the period 2009-2011 were considered in the procedure of delimitation. Bydgoszcz and Toruń, as the economically strongest cities in the region, were estab…
Spatial and spatiotemporal models of unemployment rate in Poland
The article show interest in modelling of economic processes which are characterized by spatial dependence. An unemployment rate indicating a level of socio-economic development of regions constitutes one of such processes. The correct quantitative description of this process, as one of more important negative socio-economic phenomena, is an important task of econometrics, in particular, of spatial econometrics. The purpose of the article is to p…
Application of economic distance for the purposes of a spatial analysis of the unemployment rate for Poland
The article presents the problem of the application of the spatial weigh matrix based on economic distance in spatial analysis of the unemployment rate. The spatial weight matrix expresses potential spatial interactions between the researched areas and forms a basis for the instruments applied in spatial econometrics. While identifying the neighbourhood, the following criteria are used: a common border, distance, and the k number of the nearest n…
Two-stage procedure of building a spatial weight matrix with the consideration of economic distance
The article discusses an essential problem of spatial econometrics which is the construction of a spatial weight matrix. This matrix expresses potential spatial interactions between the researched areas and forms the basis for spatial analyses. The objective of the paper was to consider various ways of defining the a spatial weight matrix. Consideration was given to the methods of identifying adjacency between areas in the form of neighbourhood i…
