The thematic R&D group on Institutional Economics and Political Economy brings together a collaborative community of scholars, driven by a shared passion for understanding how institutions shape the political economy and vice versa how political economy choices shape the institutions in the economy. At the intersection of economics, political science, and sociology, our group is committed to advancing knowledge and understanding of the complex interactions between institutions, politics, and economic systems. More specifically, being interested in Institutional Economics, they explore the impact of institutions, both formal and informal, on economic behavior and outcomes. From the rules and regulations governing markets to the cultural norms shaping societal interactions, our researchers delve into the mechanisms that influence economic decision-making at individual, organizational, and societal levels. Simultaneously, their exploration extends to the realm of Political Economy, where we scrutinize the symbiotic relationship between economic forces and political structures. They seek to unravel the ways in which political institutions, ideologies, and power dynamics shape economic policies, and conversely, how economic conditions influence political processes. This interdisciplinary approach allows the team to grasp the complexities of governance, policy-making, and their profound impact on economic development.
