This overview of Australasian economic thought presents the first analysis of the Australian economic contribution for 25 years, and is the first to offer a panoramic sweeping account of New Zealand economic thought. Those two countries, both at the start of the twentieth century and at its end, excelled at innovative economic practices and harbouring unique economic institutions. A History of Australasian Economic Thought explains how Australian and New Zealand economists exerted influence on economic thought and contributed to the economic life of their respective countries in the twentieth century. Besides surveying theorists and innovators, this book also considers some of the key expositors and builders of the academic economics profession in both countries. The book covers key economic events including the Great Depression, the Second World War, the post-war boom and the great inflation that overtook it and, lastly, the economic reform programmes that both Australia and New Zealand undertook in the 1980s. Through the interplay of economic events and economic thought, this book shows how Australasian economists influenced, to differing degrees, economic policy in their respective countries. This book is of great importance to those who are interested in and study the history of economic thought, economic theory and philosophy, and philosophy of social science, as well as Australasian economics.
