Reams of recent research underscore the critical role women play in business, and the dramatic difference they can make to the bottom line. A study by the Peterson Institute for International Economics and professional services firm EY shows a significant correlation between female leadership and company profitability. In a similar vein, a report published by Nordea—the largest bank in the Nordic region and one of the largest in Europe—suggests investing in women at the C-level pays off. Its 2017 analysis of 11,000 publicly traded companies across the globe concludes “companies run by women perform far better than the market.” The business case for gender diversity is further reinforced by new findings from management consulting firm McKinsey released in January. Delivering Through Diversity reaffirms the global relevance of the link between diversity—defined as a greater proportion of women and a more mixed ethnic and cultural composition in the leadership of large companies—and company financial outperformance.
