 While relational models and logical type spaces represent exactly the same information, their main differences is in perspective. Relational models take a third person bird’s eye view on possible worlds. Their starting point is a set of worlds rich enough to contain all states considered possible by the relevant agents, together with accessibility relations modeling players’ information. From there, agents’ first-order beliefs at the various worlds can be read off and, subsequently, also all higher levels of information. Logical type spaces, by contrast, assume a first person perspective. They take a full description of first and higher-order beliefs as primitive and treat indistinguishability as a derived relation.
