    Does the buyer's expertise influence the result of a reverse electronic auction?: An expertise theory point of view2016In: CLC 2015: Carpathian Logistics Congress - Conference Proceedings, Tanger Ltd , 2016, p. 116-121Conference paper (Refereed)
    Abstract [en]

    This paper offers a new perspective on factors influencing the results of reverse electronic auctions (eauctions) in purchase. Using the expert-performance approach established by Ericsson and Towne [1], we examine the claim by Smeltzer and Carr [2] that qualified and experienced buyers tend to perform better in eauctions. Financial savings are used as the measure of the performance. Repeated execution of e-auctions, practitioner's conference participation and positive feedback from supervisors are considered to be the factors of 'deliberate practice' described in Ericsson and Towne [1]. ANOVA and correlation is used as a statistical method to examine the data from e-auctions conducted by Czech and Slovak organizations. We conclude that expertise influences the results of e-auctions and mainly the factor of coaching and mentoring can enhance company's performance.

    Factors influencing savings from electronic auctions2014In: Central European Review of Economic Issuer (CEREI), ISSN 1212-3951, Vol. 17, p. 209-216Article in journal (Other academic)
    Abstract [en]

    The ratio of public procurement undertaken through reverse electronic auctions is increasing rapidly. Czech and Slovak municipalities use this tool to save public funds through fostering direct competition between suppliers and to increase transparency. The main aim of this paper is to analyse the savings achieved through e-auctions and the factors influencing these. Five variables are tested to establish whether they influence the savings: num-ber of participants (potential suppliers) in the e-auction, total value of the e-auction, size and country of origin of the municipality, and category of the procured product or service. Several methods are used to test independence. All of these factors except the country of origin influence the savings gained, which is in accordance with the findings of existing research.

    Examining electricity E-auctions by associated households2016In: IDIMT 2016 - Information Technology, Society and Economy Strategic Cross-Influences - 24th Interdisciplinary Information Management Talks / [ed] Petr, D; Gerhard, C; Vaclav, O, TRAUNER Verlag, 2016, Vol. 45, p. 287-294Conference paper (Refereed)
    Abstract [en]

    E-auctions held by associated households seem to be a new trend for purchasing commodity in Czech Republic. Households can achieve significant financial savings on commodities such as electricity and natural gas. In this paper, we set a goal to define and ground the associated eauctions in existing e-auctions literature, to explore their results and to analyze factors influencing their results. Using correlation analysis, we found that while the Average price per MWh after the e-auction is influenced by forward price of Electricity.

    Type of e-auctions as a factor influencing its result2015In: IDIMT-2015: Information Technology and Society - Interaction and Interdependence - 23rd Interdisciplinary Information Management Talks / [ed] Petr, D; Gerhard, C; Vaclav, O, TRAUNER Verlag, 2015, Vol. 44, p. 263-270Conference paper (Refereed)
    Abstract [en]

    The choice of the proper type of an electronic auction has become an important part of the successful result from auction usage. Basic auction types are nowadays often extruded by the others because of their relevance in particular situation and different savings that bring to purchaser. The approach of Kruskal-Wallis ANOVA was used to determine whether the savings mean vary for different e-auction types. Results of this paper can supplement the existing research in the area of e-auction complexity settings.

    Procuring commodities through e-auctions: Results and specifics2017In: IDIMT 2017: Digitalization in Management, Society and Economy - 25th Interdisciplinary Information Management Talks / [ed] Gerhard C., Petr D., Vaclav O., TRAUNER Verlag, 2017, Vol. 46, p. 245-252Conference paper (Refereed)
    Abstract [en]

    E-auctions are commonly used to purchase large variety of items, including commodities. Most of current e-auction literature presumes e-auction should perform better than diversified products, usually based on their easier specification (e.g. Kaufmann & Carter, 2004) or vast supplier base (e.g. Parente et al, 2010) . We empirically test this assumption using large dataset of real e-auction cases and two methods of calculating e-auction results, concluding that there is no statistically significant difference for savings based on estimated price, while savings based on initial price are actually lower for commodities. We provide discussion on this fact, using the agrument of Beall et al (2003), who state that commodities tend to have lower margins.

    What Drives Gamers to Buy Virtual Goods?: A Comparative Study of European Gamers2018In: Proceedings of the 4th International Conference on European Integration 2018 (ICEI 2018), PTS 1-3 / [ed] Stanickova, M; Melecky, L; Kovarova, E; Dvorokova, K, Ostrava: VŠB - Technical University of Ostrava , 2018, p. 729-738Conference paper (Refereed)
    Abstract [en]

    Nowadays, free-to-play revenue model is growing in popularity with both game developers and players. The basic game is provided free of charge, but players are encouraged to purchase virtual goods, varying from cosmetic elements such as new skins for game character to items offering significant advantage over other players. Due to the relative newness of this phenomena, little research has been devoted to this topic, especially in the European region. In this paper, we identify, motivations and antecedents influencing the purchasing behavior of free-to-play Gamers, such as the support of the game developer, gaining advantage in the game or player's relationship to their game character. We conduct a quantitative study of 1 107 European garners (from Czech Republic and Belgium) to compare whether overall attitude, average spend on virtual goods and factors influencing customer's behavior vary accross the nations. This approach also allows us to develop a typology of free-to-play Gamers in Czech Republic and Belgium.

    Assessing the personal traits and skill required for purchasing jobs2018Conference paper (Other academic)
    Abstract [en]

    Based on the thematic analysis of 432 job postings, this paper explores the desired purchasing professional skills and personality traits. We conclude that more complex skills are required with increasing buyer seniority. The desired buyer personality traits mix, on the other hand, remains stable across hierarchical levels and is dominated by the Conscientiousness characterised as independence, responsibility, compliance, and risk aversion. We argue that the observed personality traits mix suggests the prevailing transactional and support procurement role in companies.

    The Verification of Structural Decision-Making Model for Evaluating Education on Facebook2013In: Journal of Competitiveness, ISSN 1804-171X, E-ISSN 1804-1728, Vol. 5, no 3, p. 76-89Article in journal (Refereed)
    Abstract [en]

    The aim of this paper is to present the work of the research team who tried to construct a model that explores general opinions of students about education on Facebook and also opinions of students about education on the social page for course E-marketing by using structural equation model. Facebook has already been present at universities due to the fact that students use it as a primary source of information about news in courses, duties, and so on. The research team carried out an experiment in the course E-marketing at FE of VŠB – TUO, in which Facebook was used as a tool for communication between students and teachers. The research on the attitude of students towards education on Facebook was conducted by questioning using predefined variables. The first form of the model was designed by factor analysis with method Varimax, when six groups of factors that affect respondents´ opinions about education were defined. A structural equation model was used to verify the validity of the model. It appears that four groups of factors mainly affect respondents´ attitudes to this type of education according to the testing performed. These groups of factors are Engagement, Information and Modern Technologies, Lecturers and Scores, and Education on Facebook. The research team also determined statistically the most significant variables in these factors that affect the opinions of students about education the most.
