The author distinguishes and comments on three different forms of the institutional turn: thematic, methodological, and ontological. He argues that there is a wide range of institutional turns that have been undertaken for quite different theoretical, empirical, and policy-related reasons; and suggests that the returns from any given institutional turn are by no means guaranteed to be positive. The different senses in which `institutions matter' are explored and the need to contextualize the institutional turn, both at more macro and at more microlevels, is also emphasized. One way of undertaking this contextualization is through the `strategic ^ relational approach' with its concern with both the structural and the strategic dimensions of a contextualized institutional analysis. As well as presenting the approach in general terms, the author also illustrates its relevance to the spatiotemporal dimensions of institutional analysis. Eight broad conclusions about the institutional turn are presented.
