RT Journal Article T1 Do ‘soft law’ board gender quotas work? Evidence from a natural experiment A1 Mateos de Cabo, Ruth A1 Terjesen, Siri A1 Escot Mangas, Lorenzo A1 Gimeno Nogués, Ricardo AB In a new era of “open governance”, in which societal and corporate change is taking place, 15 predominantly European countries, including Spain, enacted board gender quotas to increase the share of women on boards. In this paper, we explore the effectiveness of the European Union’s first “soft” quota the 2007 Spanish Gender Equality Act recommending all large public and private Spanish firms to appoint a target of 40 percent of each gender to serve as board directors by 2015. The Act provides an incentive in that quota compliant firms may receive a preference for the tendering of public contracts. We draw on institutional and resource dependency theories to motivate the first empirical test of a “soft” quota which is distinct from Norway’s “hard law” board gender quota, and more similar to the proposed EU-wide quota. Using a large novel panel of 767 Spanish firms and 2786 firm-year observations from 2005 to 2014, we exploit the Spanish Act as a natural experiment and employ a difference-in-differences model. We find that less than nine percent of targeted firms fully comply with the quota. Firms that depend on public contracts are significantly more likely to increase female representation, although quota compliant firms do not actually benefit from the Act’s potential incentive. The results highlight the Spanish government’s lack of commitment to the quota, and that the quota’s normative obligations did not trigger the adoption of gender-balanced boards.
