Several definitions for corporate social responsibility (CSR) exist and these vary greatly as to the activities it should cover and their motivators. Among the benefits of CSR are positive marketing/brand building, brand insurance and employee loyalty. Numerous arguments against CSR prevail, e.g. social responsibility is not a problem that belongs in the sphere of activities a corporation should be addressing or even that CSR distracts businesses from addressing the primary need to concentrate on sales. Thus, the strong economic question: is CSR worth it? In 2014, we carried out a representative survey in Hungary, in which the effects of responsible business practices on consumer purchase behaviour were studied. With our research results, we could show that there is a considerable gap between the apparent interest of consumers in CSR and the limited role of CSR in purchase behaviour.
