Paper 1 investigates the factors that result in a cultural normalcy for firms to break rules as well as the strategic implications of this normalcy, using the social psychological lens of anomie theory. The analysis is at the firm level with data collected through a firm-level survey of Mexican firms, an appropriate sample given the cultural tendency to undermine rules that is considered characteristic of the country. Paper 2 considers how an act of unethical behaviour by a single firm, in the form of a scandal, can have reputational repercussions to a broader scope of firms due to the cognitive limitations of individuals which causes them to conceptually stratify firms into categories. The paper is purely theoretical and attempts to contribute to the literature by broadening the theoretical understanding of the phenomenon. It's focus is not the effect of scandals on the firm that commits them, but rather the spillover effects to firms that are perceived as related to the firm. The level of analysis of the paper is therefore at the group level , where the boundaries of the spillover determine the scope of firms which constitutes the group. Paper 3 examines how a void of ethics in the institutional environment, in the form of corruption, affects the innovation activities of firms. The context is specifically developing countries where corruption is considered a severe problem. The focus is shifted in this paper to the broader, institutional-level environment of countries and the conditions they create for firms. Hypothesis are tested using quantitative data of a sample of firms across countries in the developing world in which corruption is thought to be a severe obstacle to business. Together, these three papers are able to provide broad coverage on the issue of unethical behaviour of firms by examining the antecedents that cause it to become normalized (paper 1), the broader consequences that unethical behaviour of a firm has on the fate of a broader scope of firms (paper 2), and the strategic implications of unethical behaviour (paper 1 examining the effect that the normalization of unethical behaviour has on strategic behaviour, paper 3 examining specifically how unethical behaviour in the form of corruption affects innovation).
