The European research elite: a cross-national study of highly productive academics in 11 countries
Marek Kwiek
TL;DR
Highly productive academics are a rare and consequential segment, yet prior research has offered limited large-scale, cross-national evidence about who enters this group. Using quantitative survey data from 11 European systems, the paper examines individual and institutional predictors and finds that the top 10% account for nearly half of academic knowledge production, with broadly similar characteristics across countries.
Problem
Highly productive academics are a rare scholarly theme, and large-scale cross-national evidence about their characteristics and predictors has been limited.
Method
The study analyzes 17,211 survey responses from 11 European countries, identifying research top performers as the top 10% within each national system and research-field cluster.
Results
The top 10% of academics provide almost half of academic knowledge production across the 11 systems, while top performers consistently show longer working hours and higher research orientation.
Takeaways & Limitations
The findings corroborate systematic inequality in European knowledge production and indicate that research top performers are broadly similar across national contexts, with individual factors prominent among their predictors.
Takeaways & Limitations
Publication data were self-reported and may differ by nation, discipline, and gender, although the authors found no systemic error or bias.
Abstract
from arXiv · showhide
In this paper, we focus on a rare scholarly theme of highly productive academics, statistically confirming their pivotal role in knowledge production across 11 systems studied. The upper 10 % of highly productive academics in 11 European countries studied (N=17,211) provide on average almost half of all academic knowledge production. In contrast to dominating bibliometric studies of research productivity, we focus on academic attitudes, behaviors, and perceptions as predictors of becoming research top performers across European systems. Our paper provides a (large-scale and cross-country) corroboration of the systematic inequality in knowledge production, for the first time argued for by Lotka and de Solla Price. We corroborate the deep academic inequality in science and explore this segment of the academic profession. The European research elite is a highly homogeneous group of academics whose high research performance is driven by structurally similar factors, mostly individual rather than institutional. Highly productive academics are similar from a cross-national perspective, and they substantially differ intra-nationally from their lower-performing colleagues.
Introduction
The paper examines highly productive academics in Europe, asking who belongs to this group and which individual or institutional factors are associated with entering it. It extends rare prior work through a large-scale, cross-national study of 11 countries.
- 10% of academics produce almost half of academic knowledge output across the 11 countries studied.
- The study empirically tests expectations from smaller-scale and single-nation research on highly productive academics.
- It compares highly productive academics with other research-involved academics within countries and examines similarities and differences across national systems.
- The paper reports bivariate findings on research time and teaching/research orientation before presenting further research findings.
Analytical framework
The analytical framework situates extreme productivity within established individual and institutional explanations while distinguishing qualitative and quantitative approaches. This study adopts a quantitative approach combining behavioral and attitudinal data with publication data across broader national and disciplinary coverage.
- Research productivity has been linked to departmental size, disciplinary norms, reward systems, individual motivation, research time, collaboration, training, seniority, and institutional climate.
- The sacred spark theory attributes productivity differences to predetermined differences in scientific ability and motivation.
- Accumulative advantage theory proposes that productive scientists become more productive, while low performers become less productive over time.
- Utility maximizing theory proposes that researchers reduce effort over time when other tasks appear more advantageous.
- Qualitative studies offer productivity practices and examples, whereas quantitative studies combine behavioral and attitudinal survey data with publication data.
- Prior productivity research has focused mainly on single nations and selected fields, while this study uses national samples across five broad academic-field clusters.
Data and methods
The study analyzes 17,211 survey responses from 11 European countries, identifying top performers as the highest-productivity 10% within each national system and field cluster. It combines descriptive and inferential analyses while acknowledging important limits of self-reported and anonymized data.
- Productivity was defined as the self-reported number of journal articles and academic-book chapters published during the three years before the survey.
- Top performers are the highest-productivity 10% of research-involved academics within each national system and each of five major field clusters.
- 45.9% of journal-article production came from about 10% of highly productive academics across the European systems studied.
- The analysis begins with working-time and teaching/research-orientation comparisons and uses t tests, z tests, and logistic regression for multidimensional relationships.
- Self-reported publications may differ across nations, disciplines, and genders, while anonymization prevents comparing top performers by institutional prestige.
Research findings
Across the 11 European systems, research top performers differ from other academics through greater research orientation, longer working hours, and predominantly individual predictors. These associations vary by country, and the authors caution that correlates of productivity do not establish causal relations.
- Working time: 6.2 h is the mean annualized total working-time difference between top performers and the rest, ranging from 2.2 h in Italy to 10.2 h in Germany.German and Norwegian top performers spend substantially more full working days in academia than other research-involved academics.
- Working time: 7 countries show significantly longer research hours among top performers, while total working hours are longer in all 11 countries studied.Top performers also work longer administration hours in seven countries, service hours in three, and other academic activities in four.
- Role orientation: In all systems, top performers are more research-oriented than the rest, while primarily teaching-oriented academics virtually do not belong to this group.The share primarily interested in teaching reaches at most 2% in Ireland and is 0% in most countries.
- Predictors: Individual-level predictors are more important than institutional-level predictors in both frequency and regression-coefficient size.Institutional predictors are statistically significant in only two cases across Switzerland and the United Kingdom.
- Predictors: Age increases the odds of becoming a top performer by about 3.5% per year in Ireland and Switzerland and by 10.5% in Portugal.The model identifies age as a powerful predictor in four countries.
- Predictors: Senior academic rank is the single most important model variable, reaching statistical significance in six countries.In Finland, Germany, Ireland, and Norway, senior faculty rank increases the odds of becoming a top performer more than threefold.
- Interpretation: Associations between productivity and predictors should not be interpreted as causal relations because productivity may also affect outcomes such as professorial status.The authors describe the relationship between productivity and professorial rank as potentially reciprocal.
- Predictors: Research hours and research orientation are powerful characteristics descriptively, but the multidimensional model identifies them as determinative predictors only in selected countries.Research hours are determinative in Germany, Norway, and the United Kingdom; research orientation is determinative in Ireland and Poland.
Discussion
Top performers consistently work longer hours and show stronger research orientation, but regression results reveal that these predictors vary across countries and model specifications. Individual-level factors generally explain more than institutional factors, while research orientation is less robust than expected.
- Longer working hours and higher research orientation characterize top performers across countries.Top performers work significantly longer overall, while teaching exceeds research time among the rest of academics in Ireland, Italy, and Poland.
- Individual-level predictors have greater overall determinative power than institutional-level predictors.Academic seniority and overall research engagement emerge as powerful correlates of high research productivity.
- Regression models support research hours and research orientation as predictors in selected countries only.Although both variables strongly characterize top performers in inferential analyses, annualized research hours and research orientation are powerful predictors in no more than three and two countries, respectively.
- Country-specific and country-fixed-effects models produce different conclusions about demographic and research-orientation predictors.Mean weekly research hours increase the odds in both models, but research role orientation is significant in only two countries and insignificant in the single European model.
- Research time investment is more consistently predictive than research role orientation across the logistic models.Research orientation is significant in only two countries and insignificant in the single model, whereas research time investments are significant in both modeling approaches.
- Institutional predictors are relatively insignificant, while academic seniority is significant in most systems but reciprocally linked to productivity.Age is not a significant predictor in most systems, providing only partial support for accumulative advantage theory.
Conclusions
Across 11 European systems, a small research elite produces a disproportionately large share of knowledge. This elite is highly homogeneous, with performance associated mainly with individual rather than institutional factors and characterized by internationalization, long working hours, and research orientation.
- The study corroborates systematic inequality in knowledge production using large-scale cross-national quantitative evidence.It examines academic attitudes, behaviors, and perceptions rather than relying only on bibliometric productivity measures.
- Individual factors are more important than institutional factors in explaining entry into the European research elite.The elite is described as highly homogeneous and driven by structurally similar factors that are not easily replicated through policy measures.
- Inferential and logistic regression analyses disagree about the strength and consistency of long research hours and research orientation.Both characteristics are critical in inferential analyses but receive support in multidimensional models only in selected countries.
- European research top performers are more cosmopolitan, hardworking, and research-oriented than other European academics.These characteristics are reported despite differentiated national contexts.
