This study aims to identify and explain a possible gender pay gap in the creative industry. By using the salary information of Hollywood actors, this paper restricts the analysis to a relatively homogenous group of workers. In addition, actors' human capital endowments and past performance can be measured precisely. The factors that impact the salaries of movie stars are likely to influence the pay of other high-wage employees, such as athletes and executives.

This paper uses a rich panel data set including 178 female and male actors in 973 movies released between 1980 and 2019. Using a random-effects model and the Blinder–Oaxaca decomposition approach, this paper distinguishes between a fraction of the gender pay gap that can be explained and another fraction that cannot be explained. Hence, only the unexplained residual typically obtained by estimating two standard Mincer-type earnings functions is due to discriminatory pay practices.

This study reveals a pay difference between female and male actors. Gender-specific representation in leading roles and systematic differences in performance measures can explain this pay difference. While female actors' underrepresentation in leading roles reflects consumer tastes and, therefore, reflects discriminatory attitudes, no evidence can be found for direct pay discrimination in Hollywood's movie business.

To the best of the authors’ knowledge, this is the first Hollywood study to relying on a rich panel data set that includes various measures of the human capital characteristics of the different individual actors. This paper's theoretical contribution lies in applying classic labor economics reasoning to explain pay determination in Hollywood's movie business.

Wage disparities and their consequences have long been a topic of economic research. While most papers focus on describing the development of wage differentials over time and seek to identify the reasons for the observed patterns, few attempts have been made to analyze the influence of pay inequality on economic outcomes. A unique and rather large data set from the North American team sports industry is used to address the question how wage disparities affect the performance of professional teams. First, changes in intra‐ and inter‐team wage inequality are documented. Second, the impact of wage inequality on team performance is directly analyzed. Overall, the results differ to a considerable degree between the four major leagues, suggesting that the relative importance of high‐powered incentives and cooperation is different in football and hockey from basketball and baseball.

This paper introduces the Special Issue on competitive versus non‐competitive wage differentials, a collection of papers originally presented at the 79th Conference of the Applied Econometrics Association held in Brussels in May 2002.

Game-based learning or simulation-based learning – especially Serious Games – are notions of the contemporary discourse on digitalisation in the higher education sector in Germany. These methods offer a more vivid and motivating learning context and they help to improve important competencies for reaching work-related higher education goals. This explorative study focuses on experts’ experiences with digital and non-digital serious games and their contribution towards developing self, social and management competencies, in the Bundeswehr Command and Staff College in Hamburg (Germany). Whilst there are numerous opportunities for using serious games in higher education, their use creates barriers for addressing social, as well as leadership/management competencies. In the future, game-based learning – and more specifically, digital game-based learning – could challenge the relation between learning as hard work and learn for fun, and between explicit and goal-oriented learning and implicit, incidental and explorative learning.

This study aims to investigate the effect of the material thickness and build orientation on the mass transfer of low molecular weight substances through polyamide 12 (PA12) structures produced by laser sintering (LS).

Disc-shaped PA12 sheets having a nominal thickness ranging from 700 to 2,000 µm were built in horizontal, vertical and diagonal orientations and their permeation properties to oxygen and water vapor were measured. The structural properties of the sheets were examined by X-ray micro-computed tomography, differential scanning calorimetry and polarized light microscopy.

All the LS sheets that were investigated had water vapor and oxygen permeation coefficients that are in the range of those of PA12 produced by traditional manufacturing technologies. Despite significant differences in the porosity characteristics, the permeation properties of sheets built in different orientations were similar. The pores seem to have no measurable effect on the mass transfer rates in the sheets, and the transport processes seem to predominantly follow the rules of a regular solution-diffusion mechanism. The results showed a non-significant trend toward thickness-dependent permeation coefficients, which agrees with the observed differences in the crystal structures of the sheets.

The results are an important basis for the qualification of LS technology for direct manufacturing in applications requiring special barrier performance.

This study provides new information on mechanisms of mass transport through LS PA12 and the effect of the material thickness and build orientation. Furthermore, the results enhance understanding of the structural properties of thin polymeric sheets produced by LS.
