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, Pawłowski's problem was expanded to include spatial economic research, where micro-dependencies and spatial macro-dependencies were analysed. Purpose of the article: The purpose of the article is to establish the relationship between the microparameters set for SGM agricultural macroregions and the macroparameter referring to the whole area of Poland, where the parameters describe the economic dependencies regarding the impact of the size of farms in established region on their technical equipment. In the study, the economic relationships analysed in the case of individual SGM agricultural macroregions were defined as spatial micro-dependencies, and in the case of the entire area of Poland as spatial macro-dependencies. Methods: The methodological part of the article describes the concepts of Modifiable Areal Unit Problem, causal homogeneity of spatial data, homogeneous system of sets of areal units, area and sub-areas of conclusions. The concepts of micro-dependencies and spatial macro-dependencies are presented. Basic equations allowing to determine the evaluation of the spatial macroparameter as a linear combination of spatial microparameters were also presented. Findings & Value added: In the first stage of the study, spatial micro-dependencies were identified for subsequent SGM agricultural macroregions. In the second stage of the study, the relationship between spatial microparameters for single macroregions and the spatial macroparameter for Poland was determined. Establishing the relationship allowed to determine the macroparameter estimate for the whole area of Poland.

Research background: Despite increased attention in the literature to the importance of the CEO?s brand for companies, understanding of the effect of the CEO brand on the corporate brand remains limited. To contribute to this discussion, this paper investigates different facets of the impact of the CEO brand, and particularly its media coverage, on corporate brand equity. Purpose of the article: This study investigates the relationship between the different aspects of the CEO brand?s media coverage and corporate brand equity. Methods: Comprehensive media monitoring in the press and online sourcing of CEOs from the strongest Polish brands were conducted. For three years (2014?2017), media monitoring covered 81 CEOs, resulting in over 44,000 data points for this study. Regression analysis was conducted to determine whether a relationship exists between different facets of the CEO?s personal brand and company brand equity. Findings & value added: This study provides a new perspective on the relationship between the CEO and corporate brands and showcases empirical evidence of the CEO brand?s relationship with corporate brand equity. It introduces two relevant and novel variables (CEO brand reach and CEO brand advertising value equivalent [AVE]) to the literature, which have been limited to the number of mentions and its sentiment. Accordingly, this study contributes to the emerging literature of CEO branding within the branding field. Contrary to expectation, the intensity of media coverage alone was not significant. Results indicate that reach and AVE of CEO media exposure are reflected in the corporate brand equity. The study also finds that negative sentiment toward a CEO?s brand negatively affects corporate brand equity. The study adds to the growing stream of literature on the role of CEO brand.

Research background: In 2020, all the world's economies faced a new, special phenomenon – the coronacrisis caused by the pandemic, and with the fall of most economic indicators. In the current conditions, it is extremely important to build a competent monetary policy in order to soften the "blows" caused by the global recession for national economies. Purpose of the article: The main purpose of the presented article is the analysis of measures to stimulate the economy using monetary policy instruments in the conditions of the coronacrisis. Methods: To conduct the study, we used official statistics data, on the basis of which an econometric model was built, which allowed us to determine the forecast values for inflation, taking into account the impact of monetary and non-monetary factors. Findings & Value added: The econometric analysis show the high importance of non-monetary factors of inflation. This makes it difficult to assess the monetary policy, since Central banks are able to influence non-monetary factors only indirectly. The paper notes the influence of the refinancing rate on loans to the real sector of the economy, since the stabilization monetary policy should be primarily aimed at maintaining economic growth. The correlation field of the relationship between the index of rigidity of restrictions developed by the University of Oxford and loans to small and medium-sized businesses is constructed. It is noted that with the reduction of administrative restrictions, the volume of loans granted to small and medium-sized businesses increases.

Orientation: There is startlingly little economic research on the South African wildlife sector which contributes toward disputes regarding the economic contribution of the sector.Research purpose: The purpose of this article is to put into context the relative economic contribution of the wildlife ranching sector, as opposed to other land-use options in South Africa.Motivation for the study: Growth in the wildlife ranching sector at the cost of other traditional farming practices resulted in disagreements amongst various role players about the impact thereof on the national economy. The controversy can most probably be explained by different beliefs, coupled with the lack of a proper understanding and quantification of the wildlife ranching sector’s contribution toward the economy.Research methodology: The study employed a Social Accounting Matrix-based Leontief multiplier analysis for South Africa.Main findings: Results from the multiplier analysis revealed that developments within the wildlife ranching sector are likely to make a relatively more superior contribution towards the economy, especially when compared to similar land-use options such as extensive livestock production.Practical/managerial implications: It has been acknowledged by both academia and private sector that a major need exists for more research on the South African wildlife ranching industry, specifically looking at issues such as the industries, economic and social contributions, potentials and constraints. The research, therefore, contributes toward the depth of economic information and research regarding the South African wildlife sector.Contribution/value added: The research provides valuable information in dealing with the ‘popular belief’, especially amongst some of South Africa’s decision makers, namely, that growth in the wildlife ranching sector is not or does not have the ability to contribute significantly toward economic and socioeconomic factors.

The research aims to examine the effects of exchange rate changes on the value of bilateral export of differentiated products in the selected CESEE countries, while controlling the impact of traditional gravity variables. Identifying the determinants that affect the export of high value-added products is of particular importance for this group of countries, while analyzing the effects of exchange rate changes is a contribution to the previous researches. In order to comprehensively understand the relationship between the observed variables, a quantile panel regeression was used to estimate the gravity equation. Examining the heterogeneity of the impact of exchange rate changes and other selected trade factors along the export distribution is another contribution of the paper, given that bilateral trade researches are usually based on assessing the average impact. The results indicate that the CESEE countries' export of differentiated products is significantly influenced by exchange rate changes. Exchange rate volatility has a negative impact, which grows at higher levels of export. The heterogeneity of the impact depending on export level was also confirmed for other determinants discussed in the paper.

The way the researcher groups his research data will influence the result of his work. In the literature, this phenomenon is treated as a Problem of the Modifiable Areal Unit. The objective of this article was to analyze the three spatial levels by Municipalities, Regional Centers and Mesoregions using the following data: gross domestic product, effective agricultural production, grain production and gross value of agricultural production for the state of Paraná-Brazil in the period since 2012 until 2015. The methodological procedure studied data from the Paranaense Institute for Economic and Social Development of the above-named variables collected on the website of the Paranaense Institute for Economic and Social Development of the 399 municipalities, 23 regional centers and 10 mesoregions. The results found show the presence of the Modifiable Areal Unit Problem, presenting different results for each level of grouping. The study revealed the problem of the modifiable areal unit is a relevant occurrence and it should be disregarded by researchers who work with clusters of spatial data in their studies. The results found allow a better understanding of the scale effect and demonstrate the efficiency of spatial analysis in socioeconomic data.

Consumers spend more time shopping and expect value-added options like backgroundmelodious songs, ample car parking, good ambience, prayer halls and rest rooms. The mainconcern is whether these facilities prolong consumers stay in the store and increase businesssales. This research article is about the relationship between the background music tempo andthe duration of consumers’ stay in the stores. Data from 177 respondents were received andanalyzed. The results show that the tempo of music is significantly affecting the emotionalstate of the consumers; fast tempo music increasing the pleasure and arousal levels. Slowtempo music has consumers stay longer in restaurants and supermarkets. However, the tempoof music does not play a significant role in manipulating the duration consumers spend in abook store and apparel shop.Keywords: Background Music; Arousal; Consumer Behavior; Shopping Experience; Stimulus-Organism-Response (S-O-R) Model.
