This document provides an overview of research on the impact of populism on multilateral institutions. It defines key terms like globalism, globalization, and populism. It also outlines an approach to understand how ideas have impacted institutions like the Bretton Woods organizations using a model of path dependent, punctuated equilibrium. This model treats ideas as exogenous events that can act as critical junctures shaping the evolution of these institutions over time. The research aims to apply this model and case studies to analyze how populism has affected the nature and role of multilateralism.
