Abstract
We investigate the impact of collaborative research in academic Finance literature to find out whether and to what extent collaboration leads to higher impact articles (6,667 articles across 2001–2007 extracted from the Web of Science). Using the top 5 % as ranked by the 4-year citation counts following publication, we also follow related secondary research questions such as the relationships between article impact and author impact; collaboration and average author impact of an article; and, the nature of geographic collaboration. Key findings indicate: collaboration does lead to articles of higher impact but there is no significant marginal value for collaboration beyond three authors; high impact articles are not monopolized by high impact authors; collaboration and the average author impact of high-impact articles are positively associated, where collaborative articles have a higher mean author impact in comparison to single-author articles; and collaboration among the authors of high impact articles is mostly cross-institutional.

Notes
In some disciplines such as clinical medicine, there may not be significant differences between citation counts on articles published in journals of high, moderate and low impact factors (Falagas et al. 2010).
The sub-samples of different types of article are independent because given that citations are based on an article and not directly attributed to authors per se, the probability of observing a particular citation count, say, for a single-author article, is independent of the probability of observing the citation count for an article with two-authors where one of the authors is the same person as that of the single-author article. In other words, we maintain that we cannot predict the citation count for one type of article based on our knowledge of the citation count for another type of article.
Annual mean citation counts for each of the seven publication years in the study indicate a steady rise over the 4 years following publication (numbers are available from the authors).
A comparison between type 1 and type 5 articles was not attempted because there are only three observations in the latter type in the sub-sample of top 5 %.
Given that Europe comprises the second largest continental affiliation, mathematically we would expect to see its corresponding annual proportions move in the opposite direction to that of North America.
Bordons et al. (1996) report on the relationship between types of collaboration in Biomedicine research emanating from Spain and expected impact factors. Expected impact factors under international collaboration are significantly higher compared to domestic or local collaborations. Bordons et al. also report that international collaboration leads to higher visibility for Spanish scientists because they publish in higher impact journals.
