Until the end of the early 1970s, from a history of economic thought perspective, the mainstream in economics was pluralist, but once neoclassical economics became totally dominant it claimed the mainstream as its own. Since then, alternative views and schools of economics increasingly became minorities in the discipline and were considered ‘heterodox’. This book is in honour of John Edward King who has an impressive publication record in the area of economic theory with specific interest in how economic thought in the past shapes current economic theory and enforces certain paths of economic policy and economic development. This book is divided into five themes based on King’s interests. The first theme looks at the challenge in trying to reclaim pluralism in economics. The second faces head-on the direct collision of mainstream economics with history of economic thought and heterodox economics. The third addresses classical economic ideas, their central influence in the past and how they can still primarily guide modern pluralist economics. The fourth examines Post Keynesian and Kaleckian economics with a view to providing a more coherent and extensive branch of heterodox economics. The final theme critiques the policy of neoliberalism that has entrenched itself in capitalist economies which have led to financial, industrial, labour, and behavioural/consumerist crises. This text aims to provide a clear path for pluralism to serve the economics discipline as its standard bearer, and to no longer be merely a heterodox challenge to the mainstream. This book is of interest to those who study history of economic thought, political economy and heterodox economics.
