The effects of cognitive ability and high school quality on college entry decisions: nonparametric estimation of parameters of interest

The decisions to attend college are analysed and nonparametric predictions compared to those obtained from the widely used logit model. The impacts of measured cognitive ability and proxies for high school quality on the decisions to attend college are examined for a sample of white and black males and females from the USA. Two different parameters of interest which isolate the effects of ability and high school quality on college entry decisions are described and estimated by ‘integrating out’ the effect of other covariates. It is found that measured cognitive ability is an extremely important determinant of college entry for all race and gender groups. At the same point in the ability distribution, blacks are more likely to select into college than whites, and females more likely than males of the same racial group. Proxies for high school quality such as teacher education, student teacher ratios, school enrolment and library size are shown to have little or no effects on the likelihood of college entry for all race and gender groups. Further, predictions obtained from the flexible nonparametric analysis are found to be quite similar to those obtained from the logit model, suggesting that simpler fully parametric binary choice models perform quite well as modelling college entry decisions.     

The role of shorting,firm size,and time on market anomalies

We examine the role of shorting, firm size, and time on the profitability of size, value, and momentum strategies. We find that long positions make up almost all of size, 60% of value, and half of momentum profits. Shorting becomes less important for momentum and more important for value as firm size decreases. The value premium decreases with firm size and is weak among the largest stocks. Momentum profits, however, exhibit no reliable relation with size. These effects are robust over 86 years of US equity data and almost 40 years of data across four international equity markets and five asset classes. Variation over time and across markets of these effects is consistent with random chance. We find little evidence that size, value, and momentum returns are significantly affected by changes in trading costs or institutional and hedge fund ownership over time.     

Characteristics of a Logistics-Based Business Model

In companies where excellence in logistics is decisive for the outperformance of competitors and logistics has an outspoken role for the strategy of the firm, there is present what we refer to here as a “logistics-based business model.” Based on a multiple case study of three Nordic retail companies, the purpose of this article is to explore the characteristics of such a logistics-based business model. As such, this research helps to provide structure to logistics-based business models and identifies a way forward for companies for whom logistics and distribution are a major concern for the overall strategy of the firm.     

Demographischer Wandel und dessen Auswirkungen auf den Energieverbrauch in Hamburg und Mecklenburg-Vorpommern

This study estimates the impact of demographic change on energy use in two German regions, Hamburg and Mecklenburg-Western Pomerania. Data from the EVS household survey are used to identify demographic characteristics and age-specific consumption patterns in the two regions. They are used in combination with regional household projections to construct consumption expenditure forecasts, which are then entered as demand impulses into regional input-out-put models to calculate sectoral production effects and energy use. The analysis shows that the impact of demographic change on energy use differs considerably between the two regions. Therefore, studies conducted at the national level may miss important effects, making it necessary to conduct more studies at the regional level.     

Markenkommunikation 2.0 — Konsumenten formen Markenbotschaften

Zusammenfassung  Hoch involvierte Konsumenten agieren zunehmend als Sender von Markenbotschaften. Sie m?chten an markenpolitischen Fragestellungen partizipieren. Aus diesem Wunsch resultieren durch die ausgepr?gte soziale Vernetzung und die Entkopplung der Kommunikation neue Herausforderungen für die Kommunikationspolitik. Denn die konsumenteninitiierte Kommunikation birgt durchaus Gefahren, die vom Unternehmen rechtzeitig gemanagt werden sollten. Die Chance, von der Meinung ihrer Konsumenten zu profitieren, nutzen bislang noch zu wenige Unternehmen.

The impact of demographic change on energy use and greenhouse gas emissions in Germany

This paper estimates the impact of demographic change on energy use and greenhouse gas emissions in Germany. Since old people display different consumption patterns than young people, an increase in the proportion of old people affects overall consumption patterns. Micro data from a household survey are used to identify age-specific consumption patterns and to project the impact of demographic change on the structure of total consumption expenditure up to the year 2030. The resulting final demand vectors are entered into an environmental input-output model, which allows the calculation of sectoral production, energy use and greenhouse gas emissions. The model results suggest that until 2030, demographic change raises the share of methane in total greenhouse gas emissions and does not contribute to reducing energy use and greenhouse gas emissions in Germany. The model is also used to explore the effects of redistributing income between age groups and a policy-induced switch from motor vehicle use to public transport.     

Task Conflict,Narcissism and Entrepreneurial Capability in Teams Planning a Business: A Moderated Moderation Approach to Explaining Business Planning Performance

Drawing on the dynamic self‐regulatory processing model of narcissism, we hypothesize that in teams planning a business, task conflict relates positively to business planning performance and that this link is reinforced by the team's narcissism. By integrating aspects of human capital theory, this brighter side of narcissism is amplified where the narcissism is aligned with entrepreneurial capability and the team members' belief in their entrepreneurial capability. The findings of the moderated moderation analysis examining 66 teams of entrepreneurship students support the study's assumptions and provide meaningful implications for social psychology and personality researchers in entrepreneurship.     

The need for services and technologies in physical fast fashion stores: Generation Y’s opinion

ABSTRACT

This study answers the question of in which services and technologies should fast fashion retailers with physical stores invest. Fifteen improvement options were identified through a literature review, corporate practice and expert interviews. Then, a sample of 255 members of Generation Y evaluated and classified these options as attractive, indifferent, must-be, one-dimensional, or reverse according to Kano’s approach using the segmented Kano perspective. Results show that Generation Y generally values service improvements (e.g. with respect to salesperson friendliness and competence) higher than technology improvements. However, this evaluation differs among customer segments: whereas quality-conscious fast fashion shoppers are mainly indifferent to technology improvements, other customer segments rate ‘3D Bodyscan’, ‘Barcode App’, ‘Click&Collect’, ‘iDressroom’, ‘iTerminal’, ‘Loc Aware App’, or ‘Self-Checkout’ as highly attractive.

Fast food,ads, and taste in a Russian child’s mind

Research demonstrates that brands can influence children’s food preferences and potentially contribute to unhealthy consumption patterns. This article extends this line of research by investigating the complex and interacting effects of food brand marketing on experienced taste. The empirical field in a remote Russian town enabled the assessment of branding effects when entering a newly established market. Examining the combination of various advertisement features with emotional brand elicitation, we derive hypotheses about the interplay of brands and advertisement components linked to the perceived taste of a fast food meal. In Novosibirsk, Russia, 778 children and adolescents aged 10–18 years were exposed to fast food advertisements with real and imaginary brand logos and varying advertising claims. The advertisements consisted of a warning, an exaggerated credence claim, or both. A subsequently offered fast food meal—a portion of French fries—was experimentally varied and prepared to be either healthier but less tasty and unsalted, or less healthy but tastier and salted. The findings verify strong and positive brand effects on children’s taste satisfaction. Warnings in advertisements “worked” only for novel fast food brands by negatively affecting taste satisfaction, but increased taste satisfaction when applied in advertisements for established brands. Single credence claims did not improve the taste experience, but counteracted the negative effects of warnings for novel brands. Finally, the established brand influenced taste satisfaction positively when the fries were saltier. The findings reveal various opportunities for fast food marketing to artificially create taste satisfaction for potentially unhealthy food. Public health strategies that focus on advertising claim restrictions should be reconsidered in the context of possible evasion strategies of the food industry and counter‐effects of warnings among strong fast food brands.
