The Business Case for Diversity through 90 Empirical Studies
For the first time, a comprehensive compendium of international studies on the added value of Diversity & Inclusion has been published. The International Business Case Report (IBCR) is now available from ‘European Diversity Research & Consulting’, Cologne (Germany). “Especially in tough times, organisations need this kind of information to design their future strategies effectively”, says Michael Stuber, general manager of the research firm and author of several books on Diversity. The IBCR research reportanswers all questions regarding the value added of Diversity & Inclusion through the analysis of 90 selected studies. Each valid and reliable study has been systematically summarised and presented in an easy-to-use format on a single page. The bottom line of the report confirms that Diversity creates benefits in the workforce, in the market place, on financial markets and in a company’s community.
The IBCR includes 90 studies, four of which show that:
■ The return on equity (ROE) for companies with the highest representation of women in top management
positions is 35.1 % higher than for companies with lower percentages of women.
■ Medium-sized companies can save about €100,000 ($132,026) (depending on company size) through familyfriendly
■ The average sales revenues of companies with a low degree of ethnic diversity were at $ 3.1 million (€2,4
million), with a medium degree $3,9 million (€3,1 million) and with a high degree $5.7 million (€4,5 million).
■ Regions with culturally diverse workforces are more innovative in the development of new products than
regions with more homogenous workforces.
All IBCR results show that diversity in the workforce is economically advantageous if strategically approached.
“The results of this meta-analysis set a new stage for Managing Diversity in organisations,” Diversity expert
Michael Stuber comments, “90 studies explaining the linkage between Diversity, Inclusion and economic success
is more than enough to prove sceptics wrong.”
The report is particularly geared towards profit-orientated executives and HR professionals, and shows the
economic potential of targeted interactions with diverse employees and customers. It can by ordered per email at
The Report: This 135-page report consists of background information, empirical studies and practical advice.
The results illustrate avoidable risks and how value is added through Diversity Management.
Method: In this qualitative and quantitative analysis, the Project Team of European Diversity Research &
Consulting researched and evaluated scientific data bases, archives and additional sources. The studies were
chosen according to transferability, comprehension and sample size, and were each summarised on a single page.
The results were then systematically categorized according to their terrain. Outside of empirical studies, data on
societal frameworks was also researched and evaluated.
