Abstract
Purpose: The marginalization of women on boards is a heavily discussed topic across the world.
especially in Ghana. Apart from estimating the link between boardroom gender diversity and technical
efficiency of banks, this study aims to test the presence of upper-echelons theory in the Ghanaian
banking sector.
Design/methodology/approach – The study examines data from the 2000–2019 annual reports of 23
banks in Ghana. The stochastic frontier analysis is used to estimate the impact of boardroom gender
diversity in technical efficiency of banks in Ghana.
Findings: This study finds that greater boardroom gender diversity generates technical efficiencies for
banks. The results remain unchanged after accounting for bank types (listed and non-listed). Thus, all
banks benefit in terms of technical efficiency from more boardroom gender diversity. The upper echelons
theory is validated in the Ghanaian banking context. Overall, the study supports pro-gender diversity on
boards.
Practical implications: The results have implications at corporate, social and national levels. It
supports the need for policies that improve greater boardroom gender diversity.
Originality/value: This study adds to the growing number of non-developed countries by investigating
the link between the boardroom gender diversity and technical efficiency of banks in Ghana, a country
which historically has had minimal female participation in the workforce. New insight is, therefore, offered
into this relationship by using data which examines the technical efficiency of banks periods before and
after the Women in Finance Charter in 2016.
