This book investigates the fundamental social mechanisms that drive human behavior and social phenomena. Hedström, a prominent sociologist, draws upon a range of theoretical frameworks and empirical examples to dissect how micro-level interactions aggregate into macro-level social structures and outcomes. The work aims to provide a rigorous and systematic approach to understanding the causal processes that shape our social world.
