This work investigates how the British government transitioned from laissez-faire policies to active economic management following the onset of the Second World War. J. F. Wright, an academic historian, utilizes macroeconomic data and historical policy analysis to trace the evolution of state intervention. The text argues that the exigencies of wartime planning fundamentally altered the relationship between the British state and the national economy, establishing a framework that persisted into the post-war era.

Experts identify this text as a concise, foundational overview of the shift toward state-led economic planning in Britain. Readers frequently note the academic density of the prose, which is designed for students and researchers of economic history.
