This chapter focuses s on the IMF and the UNHCR as two IPAs that display a highly entrepreneurial administrative style. These IPAs share routines that combine strong policy advocacy with institutional consolidation. Taking account of the high differences in formal autonomy between the two IPAs, these similarities in administrative styles are striking. In particular, one might intuitively expect that in view of its limited autonomy the UNHCR should display a servant style. Yet, what these IPAs have in common is the perception of similarly low internal and high external constraints that facilities the emergence of entrepreneurial routines in both.
