Mathematical College Majors and the Gender Gap in Wages

College graduates with mathematical college majors earn more than other college graduates. Women are less likely than men to pursue mathematical college majors. This does not, however, explain the entire gender wage differential. In a representative cross section of recent college graduates, women earn 9 percent less than men with equally mathematical college majors. The gender wage disadvantage faced by women with technical college majors is no larger than that faced by women with nontechnical college majors.     

Berechnung des Xgen unter Verwendung von Regressionsmethoden

The “CPI-X” regulation allows a dynamic adjustment of the revenue cap. The general X factors is a correction term for the consumer price index (CPI), since the CPI does not represent the development of the efficient costs in the network sector. This article shows how the general X factor can be calculated using regression analysis and discusses its applicability in the German regulation context. The results show that the general X factor can be calculated using suitable panel methods, but also shows the practical limits of this approach: panel models often do not converge in short time series. In addition, regression analysis can only provide a prognosis for the future general X factor if stable economic and regulation conditions can be assumed. This is currently not the case in the German regulatory context.     

Old bodies,young hearts: a qualitative exploration of the engagement of older male amateur rugby union players in Taiwan

The world’s population is ageing. Engagement in physical activities that assist people to age in good health while enjoying quality of life are critical considerations for practitioners and policy-makers. In 1913, the sport of Rugby Union was introduced to Taiwan. As a form of recreational activity, the game became popular among- Taiwanese males. In recent years, older players have sought to facilitate their continued involvement in an activity that is normally played as a full-contact sport. Why these individuals continue to play, how they perceive their experience and how the sport has evolved to maintain their interest and active involvement are especially interesting to explore. Study participants were specifically chosen from an established Taiwanese rugby union club. Semi-structured qualitative interviews were conducted in 2013 with 15 amateur rugby players aged from 54 to 83 years. Results indicated that the main motivations for participants to continue playing was that it gave them ‘a sense of nostalgia and pride’, ‘lifelong friendship and belonging’, ‘pure joy and passion’, with considerations of being ‘mentally and physically active’, keeping up an involvement in ‘a real man’s sport’ and maintaining a sense of one’s ‘self-identity’ with ‘responsibility and commitment’ towards this chosen sport. Findings suggest that leisure providers need to be aware of the opportunities for reducing constraints and providing adaptations that allow older adults to immerse themselves in physically active pursuits integral to enjoying a fruitful ageing journey.     

Managers' interpretations of LCA: enlightenment and responsibility or confusion and denial?

Environmental life cycle assessment (LCA) and ‘life cycle thinking’ are popular approaches to evaluate and manage the environmental aspects of products. While LCA has been propagated as a decision‐making tool, the interest here is in LCA as a mental model, which managers may interpret and enact differently. If LCA and ‘life cycle thinking’ manage to infuse organizations with an extended sense of responsibility, this could counteract some of the ‘organized irresponsibility’ of modern markets. However, LCA use may also lead to confusion, doubt and denial. This article explores potential managerial interpretations of LCA with a small illustration from the wholesale trade, and through a conceptualization of the illustration in terms of Hatch's ( 1993 ) dynamic model of organizational culture.

Are There Racial Gaps in High School Leadership Opportunities? Do Academics Matter More?

Participation in high school sports and leadership activities is typically associated with later adult earnings premia. In stark contrast to the large but diminishing racial disadvantage found in other measures of educational opportunity, this analysis of high school leadership development finds few examples of racial disadvantage in historical 1960 data, but an emerging disadvantage to black female students between 1972 and 2004. Earnings regressions reveal positive earnings premia to black women who engaged in sports and leadership activities as adolescents, but not to black men. Particularly large premia to higher math scores (or penalties to lower math scores) among black workers are also observed. These findings call into question any world-view in which U.S. wages are a simple function of observable worker qualifications, and highlight the continued need to monitor equitable access to educational opportunities in U.S. schools.     

Aufsichtsrats- bzw. Diversitätsmerkmale und Profitabilität von deutschen und österreichischen Versicherungsunternehmen

This paper focuses on supervisory boards and investigates various board characteristics for the largest German and Austrian insurance companies. Furthermore, the study examines the link between diversity policies and financial performance.The study reveals some differences between the two aforementioned countries, which are mainly driven by size effects. In addition, the analysis shows that larger and stock listed insurance companies have better diversity management policies and a higher proportion of female directors. There is no significant correlation between gender diversity measures and profitability.     

Distortionary company car taxation: deadweight losses through increased car ownership

We analyse the effects of distortionary company car taxation through increased household car consumption for the Netherlands. We use several identification strategies and demonstrate that for about 20 % of households company car possession increases car ownership. The annual welfare loss of distortionary company taxation through increased car ownership is generally rather small, maximally €120 per company car, and much less than the welfare loss through increased expenditure on the company car. However, for policies that exempt households from paying tax on their company car, the annual deadweight loss is likely higher. Our first-best tax policy recommendation is to increase company car tax rates. However, our current results suggest that a second-best policy, which keeps average company car taxation constant but which reduces the marginal tax on cheaper cars and increases the marginal tax on expensive cars, would be welfare improving as overconsumption of company cars will be reduced.     

A Meta-Analysis of the Effects of Disclosing Sponsored Content

The amount of literature on the effects of disclosing sponsored content has increased greatly in recent years. Although the literature provides valuable insights into the effects of disclosing sponsored content, several research gaps remain, such as inconclusive findings, boundary conditions, and the mechanisms that explain how disclosures work. This article offers a meta-analysis of 61 papers that use 57 distinct data sets to address these research gaps. The results showed that disclosing sponsored content reduced brand attitudes, credibility, and source evaluation but increased recognition, persuasion knowledge, and resistance. Disclosure content, timing, and awareness, as well as product and sample characteristics, provide boundary conditions for the positive and negative effects of disclosures. A path model that tested the mechanism of disclosing sponsored content showed that, as suggested by memory priming effect, recognition of sponsored content increased memory but did not influence evaluation. Moreover, the understanding of sponsored content influenced evaluation, but memory remained unaffected, which corresponds to the flexible correction approach (i.e., consumers try to correct their answer to limit persuasive effects).     

Short‐Term Expectations in Listed Firms: The Effects Of Different Owner Types

We report empirical evidence in line with the disciplining role of different institutional and other owner types in reducing managerial myopia. Using data from a large Nordic survey, we find that companies, to a reasonably high degree, feel that external pressure for a good result in the short‐term generates conflict with the company's long‐term goals. We test for the effect of different ownership types and find that especially in firms with a large and non‐transitory activist or fund as an owner, the perceived pressure for short‐term actions is reduced. In addition, we observe a negative association between firm profitability and short‐term pressure, and we find that younger managers feel significantly more pressure. Firms subject to greater pressure engage in more actions to accommodate that pressure. Again, the impact of a large activist owner is especially beneficial because such firms significantly less often undertake actions that have the potential to destroy value, such as deprioritizing their long‐term investments or R&D.
