Research background: The issue of price flexibility is crucial in the economy both in the aspect of company theory and its macroeconomic consequences. In a number of publications, the sources of variable price flexibility are linked to the market power of enterprises as well as the market structure that has developed in a given branch. It is difficult to indicate empirical studies that would state clearly whether price flexibility depends on the degree of monopoly or the market power of enterprises. This paper concerns that particular field of study. Purpose of the article: The purpose of the paper is to present the statistical dependence of the degree of monopoly and market power vs. price flexibility in the economy. Methods: The analysis has been conducted using aggregated data concerning Polish economy in the period from 2001 to 2013, based on COICOP. The degree of monopoly indicator was the average number of companies in a given branch, following the classical models of market structures; the market power indicator was the average net revenue from sales of products per enterprise representing a given branch; the measure of price flexibility was the probability of price variation estimated using the Calvo pricing model. It is, therefore, a frequency-based approach to price flexibility. Statistical dependence was analyzed using the Spearman's rank and Kendall’s tau correlation coefficient and simple regression models. Findings & Value added: The outcomes indicate that in the case of Poland in the analyzed period there is no statistically significant relation between the degree of monopoly and price flexibility and also between the market power and price flexibility. Thus, the findings of the analysis support the studies which reject the assumption that higher degree of monopoly or higher market power of an enterprise is followed by less flexible prices.

Research background: The analysis of the competitiveness between producers, processors and retailers in food supply chains has always been drawing a high level of attention. It has become even more topical issue for researchers and policymakers after the global food crisis in 2008. Purpose of the article: The goal of this paper is to analyse empirical studies of market power and to investigate if some supply chains are systematically more prone to excessive market power than others. Methods: For this study, we have collected a wide range of recent studies investigating the processors’ market power index in the food supply chains. In total, in our analysis, we used 472 unique market power index estimates and employed various linear regression models to investigate their determinants. Findings & Value added: Our findings suggest that, on average, the reported degree of market power in the USA is almost twice as high as in other countries. At the same time, market power estimates related to the meat, dairy and horticulture industries are systematically higher than the ones related to other supply chains. Finally, we observed that, on average, supply chains related to highly perishable products tend to have lower market power estimates associated with them, than other supply chains. Our results have important implications for future investigation of the structural source of market power and unfair trade practices.

The effectiveness of the tax system can be analysed in various ways. According to the authors one of manifestations of such effectiveness is resistance to tax evasion. This phenomenon is influenced by multiple factors, with few being the level of VAT rates and the number of rates in force in the country concerned. The aim of the considerations is therefore to analyse how the standard VAT rate as well as the number of rates affect the effectiveness of this tax. The research was based on a literature query in the field of value added tax in the European Union. In addition, the problem of tax evasion was indicated and the aggregated data on the size of the tax gap in the Member States were presented. Then, there are the results of the research for 27 European Union countries for 2011–2019. The efficiency of VAT collection was modelled using square function, determining the significance of the parameters of this function, as well as the value of abscissa, which made it possible to group the countries based on how they maintained the efficiency of VAT collection over the analysed period of time. The final part of the study concentrates on the relationship between the efficiency of tax collection and the amount of both the basic rate and the number of rates. The conclusions of the research are as follows: a tax system with a small number of reduced rates, and preferably with one relatively low standard rate, is the system least susceptible to tax fraud. The research also shows a positive correlation between the value of the basic VAT rate along with the number of preferential rates and the scale of the tax gap, i.e., in countries with a higher standard VAT rate and a greater number of preferential rates, the tax gap is greater. The study will enable further investigation into the strategy of determining the optimal VAT rate and the process of its unification. Proposed changes may contribute to increasing the efficiency of VAT administration in EU countries, reducing the shadow economy, tax fraud and positively influencing economic growth.

Purpose The purpose of this study is to examine and understand the experiences of tourists in the Turkish coffee houses in Istanbul, Turkey. Design/methodology/approach In this study, a qualitative case study method was used to analyze tourists’ comments with user-generated content technique by analyzing tourists’ comments. The data used in the study was collected through TripAdvisor, which is considered one of the most famous websites with tourist reviews and comments, between 20 May and 10 June 2020 from tourists’ reviews (n:219). Findings The findings show that Turkish coffee house experiences are heterogeneous based on the dimensions of coffee characteristics, place, satisfaction, recommendation and revisit intention, value/price and value-added experience. Moreover, value-added experience includes some sub-themes such as a memorable experience, authentic experience and culture learning experience. Originality/value There are some studies on Turkish coffee and Turkish coffee culture in the literature, but there have been no empirical studies investigating the Turkish coffee house experiences of tourists. For this reason, this study aims to examine and understand the experiences of tourists in Turkish coffee houses. Therefore, it is believed that this study will fill the current gap in the literature on tourists’ experiences of Turkish coffee houses.

Abstract Objective: This paper reviews the major family business research papers that address factors related to relationship and work-to-family conflicts. Methodology: The procedure this paper applies follows recommendations for literature reviews by Fink (2010) consisting of: (1) selecting a research question (2) selecting bibliographic or article databases, (3) choosing search terms, (4) applying practical screening criteria, (5) applying methodical screening criteria, (6) doing the review and (7) synthesizing the results. Findings: The article summarizes that, although family business research is progressing in terms of theory building, it continues to lack a systematic adoption of longitudinal, cross-national and multi-theoretical approaches. To date, research on conflict in family firms remains underdeveloped in the CEE. Value Added: Outlining the state of the art of theoretical and empirical studies by applying a resource-based view. Recommendations: Application of control variables, such as size of the business, business life cycles, generational status, type of industry and various cultural settings. Furthermore, the role of communication, sibling rivalry and perceived justice of family members could be investigated more thoroughly.

AbstractSince its introduction by Glass in the 1970s, meta-analysis has become a widely accepted and the most preferred approach to conducting research synthesis. Overcoming the weaknesses commonly associated with traditional narrative review and vote counting, meta-analysis is a statistical method of systematically aggregating and analyzing empirical studies by following well-established procedures. The findings of a meta-analysis, when appropriately conducted, are able to inform important policy decisions and provide practical pedagogical suggestions. With the growing number of publications employing meta-analysis across a wide variety of disciplines, it has received criticism due to its inconsistent findings derived from multiple meta-analyses in the same research domain. These inconsistencies have arisen partly due to the alternatives available to meta-analysts in each major meta-analytic procedure. Researchers have therefore recommended transparent reporting on the decision-making for every essential judgment call so that the results across multiple meta-analyses become replicable, consistent, and interpretable. This research explored the degree to which meta-analyses in the computer-assisted language learning (CALL) discipline transparently reported their decisions in every critical step. To achieve this aim, we retrieved 15 eligible meta-analyses in CALL published between 2003 and 2015. Features of these meta-analyses were extracted based on a codebook modified from Cooper (2003) and Aytug, Rothstein, Zhou and Kern (2012). A transparency score of reporting was then calculated to examine the degree to which these meta-analyses are compliant with the norms of reporting as recommended in the literature. We then discuss the strengths and weaknesses of the methodologies and provide suggestions for conducting quality meta-analyses in this domain.

The Impact

This study offers empirical findings on the impact of institutional variables on firm’s stock market price performance. In order to identify the influence of companies financial on NIFTY 50 Index, our sample consists of balanced panel of 30 actively traded companies (that becomes the study’s index representative) over a massive transition period, 1995–2014. Attempts have been made with a wide range of econometric models and estimators, from the relatively straightforward to (static) more complex (dynamic panel analyses) to deal with the relevant econometric issues. Results indicate that increasing debt in capital structure does not establish any significant relation with the stock prices. Earnings per share (EPS) shows a poor explanation of price variation. Economic value added (EVA) indicates a positive relation with current as well as previous year’s stock price performances. However, dividend payout (DIVP) and dividend per share (DPS) achieve negative relationship at moderately significant level. The present study confirms that performance of companies fundamental ratios will be essential and immensely helpful to investors and analysts in assessing the better stocks that belong to different industry groups.

Neutral genetic diversity across the genome is determined by the complex interplay of mutation, demographic history, and natural selection. While the direct action of natural selection is limited to functional loci across the genome, its impact can have effects on nearby neutral loci due to genetic linkage. These effects of selection at linked sites, referred to as genetic hitchhiking and background selection (BGS), are pervasive across natural populations. However, only recently has there been a focus on the joint consequences of demography and selection at linked sites, and some empirical studies have come to apparently contradictory conclusions as to their combined effects. To understand the relationship between demography and selection at linked sites, we conducted an extensive forward simulation study of BGS under a range of demographic models. We found that the relative levels of diversity in BGS and neutral regions vary over time and that the initial dynamics after a population size change are often in the opposite direction of the long-term expected trajectory. Our detailed observations of the temporal dynamics of neutral diversity in the context of selection at linked sites in nonequilibrium populations provide new intuition about why patterns of diversity under BGS vary through time in natural populations and help reconcile previously contradictory observations. Most notably, our results highlight that classical models of BGS are poorly suited for predicting diversity in nonequilibrium populations.

Different Levels

Strategic management has produced an amazing number of theories and models in the last decades. However, so far it has not succeeded in producing a good integrative model that can synthesize all the existing models. In a previous paper I proposed such a model (from now on we will refer to it as the GEMK model, in relation to Growth-EVA-Market Power-Knowledge). It is based on the two drivers of stock value creation, Economic Value Added (EVA) and growth of capital, and proposes two new testable variables, market power and knowledge. This paper is the application of the GEMK model. It shows how most of existing strategic management models impact stock value creation. It produces a valuable simplification of the discipline, eliminates confrontations, shows that several different theories are complementary, provides a new powerful critical thinking, and shows that the different theories are contingent to these four variables. Most importantly, it shows that the different theories have different levels of impact on stock value creation.
