In this research we analyze the demand for performing arts. Since the observed demand is limited by the capacity of house, one needs to account for demand censorship. The presence of consumer segments with different purposes of going to the theatre and willingness-to-pay for performance and ticket characteristics compels to account for heterogeneity in theatre demand. In this paper we propose an estimator for prediction of demand that accounts for both demand censorship and preferences heterogeneity. The estimator is based on the idea of classification and regression trees and bagging prediction aggregation. We extend the algorithm for censored data prediction problem. Our algorithm predicts and combines predictions from both discrete and continuous parts of censored data. We show that the estimator is better in prediction accuracy compared with estimators which account for censorship or heterogeneity of preferences only.
The aim of this paper is to study the influence of chief executive officers' overconfidence on corporate research and development (R&D). We analyze a sample of 766 firms from the United Kingdom, France, Germany, Switzerland, Italy, Spain, and the Netherlands between 2008 and 2013. We use 3 measures of managerial overconfidence: the press coverage of chief executive officers, his/her age, and his/her experience in the industry. Our results show that the firms run by overconfident managers actually invest more in R&D expenditures, even after controlling for country, industry, and time factors. Overconfident managers not only spend more on R&D but also amplify the effect of financial determinants of R&D such as firm liquidity or profitability. Nevertheless, overconfident managers do not invest efficiently in R&D, and these expenditures can negatively affect the value of the firm.
The article examines how identity is represented through space in Anglo-Irish literature of the Troubles in the context of public multimodal public discourse. The paper addresses the structure and the functions of the space in Anglo-Irish novels of the Troubles within the framework of visual and verbal identity. It also focuses on verbal and visual ways of identification of the place in divided society as represented in Anglo-Irish literature. The analysis of the novels demonstrated that place identity is represented in the novels and function there as a recognizable landscape marker creating a historical background of the novels. It also performs several communicative functions. Visual and verbal identity represent community solidarity and unification. In case of identity cognition of the other community representative they are seen as a an indicator of a potential threat. A more detailed view of four Troubles novels gives a picture of how place is conceptualized as an integral part of national identity.
This study is a corpus-based examination of denominal verbs with figurative meanings in the texts of the British business broadsheet The Financial Times. Based on the study of word-formation as the source of metaphoricity (Steen et al., 2010; Janda, 2011, 2014; Brdar & Brdar-Szabó, 2013) and propositional analysis (Pankrats, 1992; Steen, 2002), it presents the classification of such verbs and discusses how and why denominal verbs with metaphorical meanings were used in the journalistic discourse about business. The empirical base of this study was a 621-thousand-word corpus of the Financial Times articles from the years 2014-2015. The authors conclude that the commonness of denominal verbs is due to the conceptual and evaluative functions of metaphor. There is consideration of the implications of these findings for linguists, translators, ESP students and those interested in corpus research into metaphor.
This study provides readers with new information about key drivers of performance in the emerging area of eSports. Competitive computer gaming (eSports) is becoming increasingly popular, and the number of gamers and amount of prize money is growing. We therefore explore some key country-level characteristics that may contribute to players’ success, measured as money won. We use gamers’ prize earnings aggregated by country and a hurdle model to understand the determinants of performance. The results show that a 1% increase in GDP per capita leads to a 2.2% increase in prize money per capita. Country population is not statistically significant in the outcome model. This finding may indicate that eSports talents are not uniformly distributed across the world population. Surprisingly, post-Soviet and planned or post-planned economies are more likely to participate in eSports.
Representing ‘The Irish national self’ in Anglo-Irish literature of the Troubles is one of the key topics, which is inseparable from British national identity since these communities are intermingled in Northern Ireland and compete for space and political dominance. Little attention of critics was paid to the analysis of linguistic means of constructing national identity. This paper examines how national identity is formed in literary discourse within the framework of discourse analysis in the Troubles novels. I suggest that in the novels considered national identity manifests itself through a purposeful choice of discourse strategies (construction, destruction and justification) and language means. Conceptualizing both identities is based on conceptualizing space and religious identity but what makes them distinctive is narrating political history. Irish national identity, as represented in the Troubles novels, is based on the idea of victimization and trauma memorization, while British national identity relies heavily on mythologizing historical victory. Both identities are constructed in binary oppositions to a conflicting community and are mostly negative.
People are intent to make similar choices especially in consumer goods markets. To address both explanations of this persistence,
i.e. state dependence and heterogeneity in preferences, we use random coefficient logit model based on scanner panel data on
juice purchases. The product differentiation of the chosen category allows us to model three dimensions of state dependence on brand, size and flavor characteristics. We provide evidence that the persistence in brand choices is positively correlated with persistence in size and flavor choices, thus the consumer pattern is prone to be inertial or variety seeking in every product characteristics. Simultaneously we show that the more sensitive to price and promotional activities consumers are, the less inertial is their behavior.
It has been shown how static and dynamic characteristics could be used for a comparative assessment
of social, environmental, and economic development, as well as the development balance in social, economic,
and ecological spheres. The proposed methodological toolkit has made it possible to identify problem
areas and stably manifested dynamic disproportions in the investigated regions, which require corrective
actions in order to ensure sustainable development
Purpose - The purpose of this paper is to examine the relationship between export activity and firm performance for a positive impact of foreign direct investments. We also analyse two possible causes of the effect: technology transfer and financial support. The theoretical background is rooted in the resource-based approach taking into account multinational companies’ perspective and the specifics of emerging markets. Design/methodology/approach - We propose testable hypotheses based on a review of the theory. To test the hypotheses, we build a sample of over 500 Russian public manufacturing firms covering the period from 2004 to 2014 and estimate regression models. Given concerns about endogeneity, the instrumental variable approach for panel data, using GMM-estimator, is implemented. Findings - Consistent with the view that foreign direct investments generate spillover effects, our results support the positive impact of foreign ownership on the link between exports and firms’ performance. Our results underline the importance of foreign ownership: shareholders from developed countries can provide benefits to exporting companies through transferring advanced technologies and loosening financial constraints by lowering interest and raising availability of bank loans.
Originality/value - We provide new insights on the relationship between exports and firm performance. Given our focus on Russia, a market with high potential to draw foreign investments, our research sheds some light on how emerging country firms can benefit from having foreign shareholders with paying attention to geographical distribution of such investments. Specifically, through the overcoming of technological barriers and loosening of financial constraints, we show empirically that foreign capital can make up for weak local institutional infrastructure and enhance the company’s’ returns from internationalization.
The use of hedges has been an important topic in academic writing research. Much of this research has focused on L1 academic texts. This study investigates the use of the most frequent hedging devices in the corpus of 58 works written by Russian university students and compares it to the corpus of articles published in peer-reviewed journals in business and management. The analysis of learner corpus data and further comparison provided by the reference corpus have highlighted a number of problems which non-native learners experience when writing academic texts, e.g., phraseological infelicities and stylistic inappropriacies. Some teaching materials presented in the paper aim at helping teachers to deal with the problems identified. This study has important implications for creating EAP courses, research of second language acquisition, and writing pedagogy.
This paper investigates how the recent crisis of 2008 changed relations between innovation and firm performance in Western Europe. We apply a structural framework of CDM modelling, which incorporates different stages of the knowledge creation process and takes into account the complex nature of innovations. The study is based on a balanced panel data of 420 listed manufacturing firms from the U.K., Germany and France. All the information is gathered from common sources, thereby reducing subjectivity, a typical problem in the field. We found, the crisis resulted in appreciable changes in the model. The most important evidence is enhancement of the role of firm resources in the post-recession period. We also reveal larger barriers for innovations, increased uncertainty and lower state dependence in R&D engagement, product creation and economic performance. These results could indicate the ‘cleaning effect’ of the crisis, which has worsened the business environment and enhanced competition.
We use eSports data to construct an empirical model to measure the effect of diversity on team performance. Different kinds of diversities are considered, diversity of culture, diversity of language and diversity of skill. Our main results are that cultural diversity is beneficial for team performance: the absence of diversity reduces performance by 30%. However, language and experience diversity negatively affect results. Taking the difference in the results into account, we conclude that firms should not thoughtlessly maximize team diversity: different kinds of diversity have different integration and communication costs.
This article explores consumers` acceptance and willingness to pay for genetically modified potatoes in Tajikistan. A binary-choice contingent valuation metholdolgy is applied as a primary research tool. Results indicate that more than half of respondents are not aware of this particular product. Yet, majority of consumers expressed their positive or neutral opinion. Findings highlight the relevance and possibility to introduce and market nonconventional potatoes in a Central Asian market of Tajkistan.
According to behavioral economics, coaches may be unconsciously biased, and this could lead to deviations from rational behavior, which in turn affects team performance. We analyze the influence of a particular behavioral bias of coaches, overconfidence, on the performance of soccer teams. We use a sample of 63 coaches managing all the soccer clubs involved in the Russian Football Premier League during the four seasons between 2010 and 2013/2014. To measure overconfidence, we use a press-based metric that is generally accepted in corporate governance studies and complement it with an additional continuous measure. Coaches' overconfidence positively and significantly influences team average scores, both in the baseline regression and robustness checks. Additional testing allows us to draw conclusions regarding the inverse U-shaped relationship between overconfidence and performance. We cannot conclude that overconfidence has any effect on coaches' risk-taking that can be approximated by goals scored or allowed. We apply the well-studied methodology of overconfidence measurement to the new field of sport economics, thereby generating novel results. Although overconfidence is perceived negatively in corporate governance, we show that in sport, it is beneficial to be overconfident. The findings contribute to sport literature, more specifically to the field of performance in soccer, with results that support the importance of a coach's personal traits.
Nowadays, mind mapping is rather popular educational technique. Like any other learning tools, mind maps became a part of modern educational trends like blended learning and computer-supported collaborative learning. Lots of mind mapping software tools are adopted to teaching and learning routines such as educational content delivery or assessment. This paper focuses on the additional automatic evaluation of digital educational mind maps gained from the existing procedures of assessments. The review of automatic graders which support the evaluation process demonstrates that some systematical work is done in automation grading by comparing students’ mind maps with a template. But lots of questions about automatic mind maps’ scoring by retrieving the data from a scored mind map are still open. This paper introduces the automatic grader for educational mind maps (AGEMM) which acts like a teacher’s assistant and calculates several quantitative metrics. The AGEMM is implemented as a web-service and interacted with mind maps prepared in the Coggle web-service through its API. The AGEMM is adopted to a bachelor course. Results demonstrate that scores from the AGEMM may be transformed to scales or criterial levels which are used to evaluation. Moreover, the AGEMM application revealed several problems and shew lines of development which we discuss in the paper.
How do public-private partnerships (PPPs) differ from traditional public procurement and what role should governments play in them? This article views PPPs as collaborative projects with imperfect information between parties. Typical public procurement contracts tackle asymmetric information problems yet limit feasibility of projects: some are not profitable enough to ensure private party participation. Partnership improves feasibility; this justifies PPPs as a form of public good provision and demonstrates how they differ from procurement. Four UK and Russian cases of PPP projects are analyzed within the above framework, focusing on types of contracts, contributions of both partners, and specific partnership elements.
This paper focuses on referential coherence which is seen as a crucial attribute of effective academic writing. I report findings from a corpus study of Russian students' use of anaphoric expressions in their research proposals which is compared to a reference corpus comprising research articles published in peer-reviewed journals. I hypothesise that learners use anaphora less frequently than professional writers. The results of the analysis confirmed the hypothesis and allowed me to identify particular problems connected with the students' use of anaphoric expressions. It is hoped that the reported findings will challenge EAP teachers and textbook writers to consider paying closer attention to the markers of referential coherence in a course of academic writing for L2 students.
Addressing a gap in the literature on GM food preferences, we conducted a survey in Russia, where legislation forbids GM food production and importation. Based on in-person consumer surveys and choice experiments in Perm, Russia, we estimate the willingness to pay for bread containing GMOs. Our results indicate that information-seeking health conscious consumers are more likely to prurchase this particular product. Our findings are consistent with previous studies of Russian consumer preferences, who find that Russian consumerss' food prurchases are often motivated by health concerns and the naturalness of foods.
This research focuses on parents’ participation in their children’s education via self-organizing through non-profit organizations (NPOs). The aim of this article is to uncover the factors which have an impact on Russian parenting organizations participating in collective coproduction in schooling. Quantitative analysis revealed three groups of explanatory variables: a) the “economic” variables, namely GRP per capita and poverty rate; b) a “high status” of a school; and c) variables capturing the “federal district effect” on the probability of collective coproduction. Results of the quantitative analysis highlight the significant discrepancies in regional conditions for emerging NPOs in coproduction in schooling.
