From the buying club’s perspective, the transfer of a player can be interpreted as an investment from which the club expects uncertain future benefits. This paper aims to develop a decision-oriented approach for the valuation of football players that could theoretically help clubs determine the subjective value of investing in a player to assess its potential economic advantage.

We build on a semi-investment-theoretical risk-value model and elaborate an approach that can be applied in imperfect markets under uncertainty. Furthermore, we illustrate the valuation process with a numerical example based on fictitious data. Due to this explicitly intended decision support, our approach differs fundamentally from a large part of the literature, which is empirically based and attempts to explain observable figures through various influencing factors.

We propose a semi-investment-theoretical valuation approach that is based on a two-step model, namely, a first valuation at the club level and a final calculation to determine the decision value for an individual player. In contrast to the previous literature, we do not rely on an econometric framework that attempts to explain observable past variables but rather present a general, forward-looking decision model that can support managers in their investment decisions.

This approach is the first to show managers how to make an economically rational investment decision by determining the maximum payable price. Nevertheless, there is no normative requirement for the decision-maker. The club will obviously have to supplement the calculus with nonfinancial objectives. Overall, our paper can constitute a first step toward decision-oriented player valuation and for theoretical comparison with practical investment decisions in football clubs, which obviously take into account other specific sports team decisions.

Management research on serendipity, which is defined as a search that leads to an unintended discovery, has increased considerably over the last three decades. In this article, management research on serendipity (up to the end of 2021) is reviewed and synthesised.

A bibliometric analysis was conducted on 85 peer-reviewed articles extracted from the Scopus database, which was then integrated with a systematic literature review.

The bibliometric analysis revealed that management literature on serendipity is framed around four main thematic areas: conceptual boundaries, conditions favouring serendipity and outcomes, foreign market entry and the relationship between serendipity, networks and assets. A systematic literature review was then conducted on each of the identified clusters.

The present article offers a systematised view of the extant body of research on serendipity in management studies. Based on the findings, the main implications and future research agendas are discussed.

The main purpose of this paper is to test the relationship between leadership competencies and effectiveness, with constraints as a mediating variable, and to introduce the main assumptions of the Bounded Leadership Model (BLM).

The total sample included 242 leaders in a top managerial position. Data were collected directly from leaders via self-reports. In total, five hypotheses were formed which related to the relationship between leadership competencies and effectiveness and the role of constraints. Hypotheses were tested by analysing several regression models and mediation effects. Moreover, internal consistency and construct validity were assessed by calculating Cronbach’s alpha and assessing the intercorrelations between study variables.

The study results demonstrate that leader’s competencies are positively related to leadership effectiveness. The authors also found an indirect effect of leadership competencies on effectiveness via constraints. Overall, it can be concluded that the scales included in the BLM have satisfactory reliability and validity indicators.

The paper examined the relationship between leadership competencies and effectiveness with constraints as a mediator. Moreover, it introduces the BLM which takes a broader view on leadership and includes variables that seem to play an important role in leaders’ adjustment and success. These findings can be applied in different training processes and also in assessment and development centres to serve as a facilitator in the process of enhancing leadership competencies and effectiveness and in overcoming leadership constraints.

The study overcomes previous research limitations because it offers a selection of leadership competencies that play an important role in leadership effectiveness, as well as may serve as a potential facilitator in the process of overcoming individual constraints. This knowledge can be used for future research and practical purposes.
