Graduate overeducation as a sheepskin effect: evidence from Northern Ireland

This article examines the nature of graduate overeducation amongst a group of applicants to a graduate conversion programme. It was found that while a substantial proportion of earnings differentials were associated with a mismatch between individual skill levels and job requirements, wage gaps were still likely to occur should such mismatches be eliminated. The evidence suggests that graduate wage levels are heavily related to sheepskin effects associated with the attainment of jobs with graduate level entry requirements. These sheepskin effects suggest that the process of job categorization is arbitrary in nature, with stated job requirements somewhat independent of actual skill requirements. The analysis suggests that graduate overeduction is better understood within the context of both skill and categorization mismatches as opposed to skill matches alone.     

The productivity impact of R&D investment: are high-tech sectors still ahead?

Our aim is to investigate the relationship between a firm's R&D expenditures and its productivity, looking at sectoral peculiarities. We use a unique longitudinal database consisting of 1809 US and European manufacturing and service firms over the period 1990–2008. Our main findings can be summarised as follows. Consistently with previous literature, the knowledge stock has a significant positive impact on a firm's productivity. More interestingly, the coefficient turns out to be significantly larger in the R&D-user services and high-tech manufacturing sectors than in the non-high-tech manufacturing sectors. Contrary to the ‘latecomer advantage’ approach, these outcomes suggest that firms in high-tech sectors are still ahead in terms of impact on productivity of R&D investments.     

Top pay transparency in Europe: codes,convergence and clichés

Following the waves of corporate scandals and the increasing attention to corporate governance, the transparency of reporting on director-level pay has increased across Europe. This article examines the extent of convergence in laws, codes and corporate reporting practices in regard to director-level pay in France, Germany, Switzerland and the UK. The paper analyses annual reports and the websites of 23 companies, using institutional theory to discuss the coercive, normative and mimetic pressures for convergence that are revealed, not just in the laws and codes in each country, but also in the standardized wording in the relevant sections of reports which have become clichés.     

Ethnic Identity in Advertising: A Review and Meta-Analysis

The corpus of research on ethnic identity in advertising indicates that (1) ethnic identity influences commonly examined attitudinal and purchase-intention outcomes, and (2) attitudes toward both the actor(s)/model(s) and the ad moderate attitudes toward brands depicted in ethnically resonant ads. Individual studies often differ by measurement type (i.e., single-item measure versus multi-item scale), study design (i.e., experiment versus survey), and diversity of respondent sample. Seemingly, ethnic-identity effects are greater for studies that relied on single-item measures, experimental designs, and more diverse samples. Implications and future research directions are suggested.     

An application of co-word analysis and bibliometric maps for detecting the most highlighting themes in the consumer behaviour research from a longitudinal perspective

This article presents an application of a bibliometric and visual study of the research carried out on a social science subfield, concretely the consumer behaviour research (CBR), from a longitudinal perspective (period 1966–2008). The study combines performance analysis and science mapping for detecting and visualizing conceptual subdomains. Quantitative and qualitative measures are used in order to identify the most prominent themes. Quantitative data are used to put together very related concepts (themes or clusters of topics), while qualitative indicators (as those based on citations) are used to measure the quality and/or impact of the detected themes. The study also uses bibliometric maps to show in a visual way the associations between the main concepts treated by the CBR community. The maps provide insight into the structure of the CBR, visualize the division of the field into several subfields, and indicate the relationships between these subfields. Co-word analysis is the bibliometric technique used to identify the main themes. All this allows us to quantify and visualize the thematic evolution of the CBR. It also helps to both experts and novices to understand the current state of the art of the CBR and to predict where future research could lead.
