“…For Moravcsik (1997), the institutional theory, referred to by him as liberal theory, is useful to analyze international regimes, organized and identifiable systems of interstate governance, to know which groups influence more than others and to evaluate preferences according to the internal point of view of states. In this sense, although the focus of Keohane and Nye (1988) is multidimensional, that is, even if it mixes aspects of structural realism in their conception, it is interesting to realize that there are similarities and differences between the focus of both authors and that they lead the understanding of how an international regime related to sustainability can be built not only by states, but also by international actors who can direct their behavior (Pourchot and Stivachtis 2014;Zhang 2020;Schrobback and Meath 2020). For similarities between Moravcsik (1997) and Keohane and Nye (1988) the case of preferences can be mentioned; it is true that the structure and the actors participate in a context that helps in the creation of these preferences, but the authors give preferences the main credit when evaluating the behavior of states, that is, it is the preferences of states that determine their behavior (the internal point of view is quite relevant in relation to the external).…”
