PurposeThis study aims to explore how responsible corporate behaviour, specifically self-imposed financial regulatory control, might subsequently be reflected in the financial performance of companies subject to such regulation.Design/methodology/approachIn this study, the authors aim to explore how financial compliance in the form of the Economic Control Regulation (ECR) has impacted on the financial performance of professional football clubs in Spain. To this purpose, the authors adopted a quasi-experimental before and after study design. This type of design assesses the object of study before and after a specific event in order to determine whether this event has had any effects on the object. In this case, the event was the coming into effect of the ECR in the fiscal year of 2012, and the object hypothetically affected was the clubs’ economic performance.FindingsThe authors can confirm that in general terms and for the whole set of clubs analysed, the ECR has had a strong and positive effect on financial performance.Research limitations/implicationsIn this study, the authors wish to establish a link between the idea of “compliance” and that of “responsible corporate management practice”. It is not just a matter of compliance with the law. The fact of complying with certain laws could, in general terms, or from the point of view of common sense, be qualified as “responsible behaviour”. However, under the contemporary concept of corporate responsibility, compliance with the law is a behaviour that must be taken for granted. Responsibility, therefore, would entail going beyond such expected behaviour to one that exceeds the environment's expectation of the corporate actor.Practical implicationsWhat extent improvements in financial performance have also boosted social performance. Confirming such a positive effect endorses the argument that ethical improvements in corporate culture have a general effect on business sustainability in its different aspects: economic, social, environmental and in governance.Social implicationsThe authors may foresee that the culture of compliance will spread from the finance departments to other management areas. Its connection with ethical business practice is directly linked to the more complex concept of the “citizen company”. There are suggest interesting bases on which professional football clubs might move from a traditional profit-oriented company model towards a more contemporary one oriented towards relationships of integrity with the sport's environment. This study shows that the ECR has been a starting point for the development of Spanish professional football clubs towards this type of “citizen company”.Originality/valueIt was a single-sector study whose principal value lies in the verification of whether responsible economic management (the main consequence of applying the ECR) had any effects on company profits, financial results and other important indicators. In addition to fostering responsibility, this new management model involves a special innovation, as it is based on self-regulation (i.e. on regulations not imposed by national or supranational states), designed and implemented to ensure the sector's viability.
