As knowledge producers and transfer agents, the Organisation for Economic Cooperation and Development (OECD) and the World Bank (WB) rely on their own research infrastructures to promote the dissemination public governance reform. To enhance their authority and legitimacy, they frame their economic knowledge through prominent documents that set the agenda for policy advisory activities and practices. This paper suggests that the influence of epistemic communities on the extent of change in these international organisations' agenda-setting depends on their institutional determinants, namely mandate, knowledge production processes and knowledge validation procedures. Both IOs strategically select their preferred sources of expert knowledge. The OECD refers to technical expertise to enhance its new public management agenda through adjustments. The WB is attuned to economic expertise, resulting in transformations of knowledge frames.

This paper sheds light on the role of regulatory agencies in framing public problems. It is well acknowledged that regulatory agencies are becoming key actors in the policy process. To this extent, a common understanding regarding the delegation of regulatory agencies relates to the fact that they solve problems rather than define them. Although the literature on framing and regulatory agencies is abundant, studies questioning the combination of these two phenomena are scarce. In this paper, a specific "framing index" is developed to measure the involvement of 36 regulators in framing issues in two sectors, namely food safety and environmental protection. This measurement is applied to a cross-national and cross-sectorial fuzzy-set qualitative comparative analysis (fsQCA). The main results indicate that when agencies are highly involved in framing, they are old, they have a low number of staff members, and the risk of venue shifting is low. El papel de las agencias reguladoras en la definici on de problemas p ublicos: un an alisis emp ıricoEste documento saca a la luz el papel de las agencias reguladoras en la definici on de problemas p ublicos. Se sabe bien que las agencias reguladoras se est an convirtiendo en actores clave en el proceso de pol ıtico. En este sentido, un entendimiento com un con respecto a la delegaci on de agencias reguladoras se relaciona con el hecho de que estas resuelven problemas en lugar de definirlos. A pesar de que la literatura acerca de la definici on de las agencias regulatorias es abundante, son escasos los estudios que cuestionen la combinaci on de estos dos fen omenos.
