Extant research on political corporate social responsibility (PCSR) has not yet addressed how the populist turn impacts PCSR theory and practice. This conceptual article analyzes how populism influences PCSR across a range of political environments. We draw on signaling and screening theories to develop a conceptual model that advances PCSR literature by proposing an information-centric approach. We highlight the necessity of high-quality information as an enabling condition for effective PCSR-related decision-making, and our model explains how the depreciation of information transparency (...) under populism impacts PCSR strategy. We thus contribute to PCSR literature with a new information-based theorization by showing how PCSR depends on the political environment and by enhancing our understanding of the role of the state in the development of PCSR strategies.
