Few would dispute that many Western industrial democracies undertook extensive deregulation in the 1970s and 1980s. Yet this narrative, in its most familiar form, depends upon several historiographical assumptions that bely the complexities and pitfalls of studying the recent past. Across thirteen case studies, the contributors to this volume investigate this “deregulatory moment” from a variety of historical perspectives, including transnational, comparative, pan-European, and national approaches. Collectively, they challenge an interpretive framework that treats individual decades in isolation and ignores broader trends that extend to the end of the Second World War.
